Of those foot and ankle injuries requiring radiographs based on the Ottawa Foot and Ankle Rules only approximately 22% will have a fracture.

This diagnostic cohort study examined if ultrasound could detect acute non-bony foot and ankle injuries. Ottawa Rules positive patients over 16 years were eligible. An ED member performed scans for injury of tendons and ligaments blind to radiograph findings. Patients without fracture were re-scanned at 2 weeks. The Foot and Ankle Outcome Score (FAOS), a validated, patient-reported outcome measure, was completed at baseline (based on pre-injury status), 2 and 6 weeks.

110 subjects participated. 99 did not have significant radiological fractures. FAOS scores were significantly different at 2 weeks compared with baseline across all subscales (p< 0.000). At 6 weeks a significant difference persisted between scores for the ‘Pain’, ‘Sport’ and ‘QOL’ subscales (p<0.043, p<0.000, p<0.000 respectively) compared with baseline. Initial post-injury USS Anterior Talofibular Ligament (ATFL) findings were significantly predictive of FAOS Subscale results for ‘Symptoms’, ‘Sport’ and ‘QOL’ - respective p values being p<0.004 95% CI (−20.184, −4.402), p<0.029 95% CI (−31.857, −1.896) and p<0.008 95% CI (−32.118, −5.561).

ATFL ultrasound status at the time of injury predicts patient perceived sporting function at 6 weeks.

In 2011 health policy dictated a reduction in iatrogenic infections, such as Clostridium difficile (C. diff), this resulted in local change to antimicrobial policy in orthopaedic surgery. Previous antimicrobial policy was Cefuroxime, this was changed to Flucloxacillin and Gentimicin. Following this change an increased number of patients appeared to suffer from acute kidney injury (AKI). We initially evaluated the incidence of AKI pre and post antibiotic change and found a correlation between the Flucloxacillin and AKI. We then made changes to antibiotic policy to mitigate the increased rates of AKI and proceeded to evaluate the outcomes.

In this prospective study all patients admitted with fracture neck of femurs were identified from the National Hip Fracture database and data obtained. The degree of AKI was classified according to the validated RIFILE criteria.

Evaluation showed a 4 fold decrease, from 13% to only 3%, in AKI after introduction of the modified antibiotic policy. C.difficile continues to be non-existent since this change.

Flucloxacillin obviously had a significant impact on this patient group. However, we have shown that with appropriate changes to antibiotic policy AKI associated morbidity can be significantly reduced. Dose dependent antibiotics will now be given based on weight and eGFR.

This study reviewed all patients who received an EXOGEN Express bone stimulating device (BSD) to treat delayed union / non-union following operative treatment for a long bone fracture & evaluate if our results are comparable with the NICE guideline expectations.

A retrospective review of records between December 2004 & January 2013 revealed 113 patients treated with a BSD. A total of 59 patients were eligible for analysis, (operative treatment for a long bone fracture with adjuvant EXOGEN BSD for non-union or delayed union). Twenty-one were open fractures.

The BSD was applied at a mean of 264 days post-operatively. Thirty-five patients went on to have a 2nd operation before union was achieved. Forty-two patients went on to union following application of the BSD. Mean time to union was 293 days. Seventeen patients failed to unite by the end of the study. There were no adverse reactions to the EXOGEN BSD in this cohort.

This study has shown that the use of an EXOGEN BSD is a safe, non-invasive method to successfully treat long bone non-unions following initial operative surgery, with potential cost savings (a potential saving of £48,888 to the hospital according to NICE estimations) compared to the standard re-operative management.

There is strong evidence to support the use of bisphosphonates in the prevention of osteoporotic fractures. There has, however, been growing concern that prolonged use of bisphosphonates can lead to the development of atypical femoral fractures and can protract healing time.

We conducted a retrospective study looking at all femoral fractures between 2011–2013. Of 109 patients, 12 were diagnosed with atypical femoral fractures. The mean age of presentation was 69 (52–92). Five patients held no history of falls and presented with hip pain. The remaining seven sustained minor falls. Seven patients were on bisphosphonates on presentation. Bisphosphonates were discontinued in five cases and continued in two. Bisphosphonates commenced in one patient who subsequently developed second fracture. All fractures were managed with intramedullary nailing. Healing time was prolonged in all cases (mean healing time 7.3 months). Three patients needed further surgeries to achieve union.

Overall, we observed that patients with prolonged bisphosphonate intake were more susceptible to atypical fractures with a delayed recovery time.

Increasing awareness amongst medical professionals may aid timely diagnoses and subsequent referrals to orthopaedics. Recognition of these fractures may also permit early discontinuation of bisphosphonates, which may prevent future fractures and reduced healing times.

Patients offered fluid two-hours preoperatively have improved satisfaction, fewer complications and no increased intra-operative risk. Our hospital has prolonged pre-operative starvation times for trauma patients. Failure-Modes-and-Effects-Analysis (FMEA) was used to identify points of inefficiency in the preoperative starvation system.

Data was collected from patients, ward-staff and computer-systems, on pre-operative starvation times and food provision following cancellation. A process map of the system was created. Failure-modes-and-effects were identified at interview and stakeholders were asked to risk-evaluate each failure-mode by providing consequence scores, probability of failure and of detection.

Over 7-days, 27 patients were reviewed. Average fasting times were 6.84 (2–22.25) hours for fluid, and 12.03 (3–28.75) hours for food. Five patients were cancelled with a mean NMB time of 17.25 (3–28.75) hours. The highest risk scores identified were regarding the decision to place a patient on the list (10), keeping patients NBM (10.16) and being cancelled and fed (10.11).

Process-mapping and FMEA can be applied to the pre-operative starvation of trauma patients to identify parts of the system that will have the biggest impact if improved. Engaging the multidisciplinary-team allowed all members to feel involved in risk assessment and quality improvement. Using FMEA should facilitate change and improve the system of pre-operative starvation.

We report the medium term outcome of a 15 degrees face-changing acetabular cup in THA due to secondary OA in DDH.

We analysed 28 Hips in 26 patients who underwent THA between May 2007and September 2009. There were 20 females and 6 males with a mean age of 52 yrs (range 33–68yrs).

All patients received a cementless Exceed Advanced Bearing Technology 15° Face-changing cup (Biomet) with a ceramic liner through a posterior approach. A cementless or a cemented femoral stem, with 28 or 32mm Biolox Delta ceramic head, was used in all cases. All patients started full weight-bearing the next day. The average clinical and radiological follow-up was for 50 months (range 36–76 months). The mean Harris Hip Score improved to 94 and the Oxford Hip Score improved to 44. There was 100% survivorship of the hip joint for both components.

Post-operative radiographs revealed integration of the cup with no signs of loosening or osteolysis. The mean covered acetabular lip inclination angle was 51 degrees (range 43–61)and the true inclination angle of the bearing was 36 degrees (range 28–46).

The clinical results support the use of the cementless 15 degrees face-changing acetabular cup in the dysplastic acetabulum.

Infection in arthroplasty surgery is a major complication leading long antibiotic courses and frequently requiring repeated operations to eradicate or suppress. Therefore in the situation of revision surgery on prosthesis that are possibly already infected a clear identification of possible infection is required. Previously frozen section samples have been used in Derriford Hospital in conjunction with clinical presentation and other investigations to aid in diagnosis and tailor management, however recent studies have suggested that this may not be as effective as previously thought. Kanner et al. (2008) suggested a sensitivity of 29% and positive predictive value of 40%.

This retrospective audit reviewed the cases between March 2007 and May 2012, identifying 220 cases of revision surgery where infection was suspected and frozen sections analysis was performed. Results where then compared to paraffin and cultured samples if taken. A notes review was performed to demonstrate if the operative technique (single or two stage) was in line with local guidelines for the results of the frozen section. Long term survival (longest follow up of 7 years) was assessed by need for revision surgery.

All patients with a MOM THR implanted at our unit were recalled for clinical examination, Oxford hip score, radiographs, MARS MRI and cobalt/chromium ion levels. Patients were sub-classified, determining further follow up: a regular screening programme or referral to a revision arthroplasty surgeon.

We identified 299 MOM THR's. 59 patients reported a recent deterioration in symptoms. 67 had an abnormal x-ray. 232 hips underwent MARS MRI: 66 showed mild MOM disease, 31 moderate MOM disease, 17 severe MOM disease. 117 had a substantial fluid collection around the hip. Serum cobalt/chromium ions were raised in 135 patients. 46 had one or both above 7 ppb. 148 THR's were referred to a revision surgeon. 21 have been revised and 14 are awaiting revision.

In total 64 hips have been revised. 13 were histologically proven ALVAL, 19 had clinical findings of ALVAL (not histologically confirmed), and 1 non-specific reaction to metal wear. 53 asymptomatic patients had evidence of soft tissue reaction on MRI and/or rising metal ions.

Our screening programme identified asymptomatic patients with evidence of a suspicious reaction to their MOM THR. We recommend all patients with a MOM THR are fully screened for ARMD regardless of symptoms and metal ion levels.

We retrospectively reviewed the mid term outcome of 88 MoM THA in 84 patients and 21Hip Resurfacing using Recap Magnum bearing surface performed during 2006 – 2009.

There were 41 males and 47 females in the THA group and 17 males and 4 females in the Hip Resurfacing group.

All procedures were performed through a posterior approach. The average head size for the THR group was 46mm and the cup size was 52mm and the average head size for the resurfacing was 50mm and cup size was 56mm respectively.

Median age for the THA group was 60 yrs. (28–73) and for the Resurfacing it was 51.5 yrs. (32–62). Average follow up was 76 months for the THA group and 78 months for the Resurfacing group.

Average serum cobalt for the THA and the Resurfacing groups were 53.2nmol/l (119) and 30.85 and the Chromium levels were 82.44nmol/l(134.5) and 67.49 respectively. Eight MRI scans showed abnormal fluid collections suspicious of ARMD in the THA group and 2 showed fluid collection in the Resurfacing group. There were five revisions in the THA group with the tissue diagnosis of ALVAL. In all except one case a well fixed uncemented stem (Taperloc) was retained.

In our series Recap Magnum on a Taperloc stem showed 94% survival at five years and therefore we continue to review the cases annually with serum cobalt chromium levels and MRI scans.

We present (with intra-operative imaging) 4 patients who sustained Pectoralis major ruptures on the same piece of equipment of the “Tarzan” assault course at the Commando Training Centre, Royal Marines (CTCRM). Recruits jump at running pace, carrying 21 pounds of equipment and a weapon (8 pounds) across a 6ft gap onto a vertical cargo-net. The recruits punch horizontally through the net, before adducting their arm to catch themselves, and all weight, on their axilla.

All patients presented with immediate pain and reduced function. 2 had ruptures demonstrated on MRI, 1 on USS and one via clinical examination. All 4 patients were found, at operation, to have sustained type IIIE injuries.

All patients underwent Pectoralis major repair using a uni-cortical button fixation and had an uneventful immediate post operative course. Patient 1 left Royal Marines training after the injury (out of choice, not because of failure to rehabilitate). All other patients are under active rehabilitation hoping to return to training.

Review of 10 years of records at CTCRM reveal no documented Pectoralis major rupture prior to our first case in October 2013. There has been no change to the obstacle or technique used and all patients deny the use of steroids.

In December 2012 the orthopaedic Hand and wrist unit at Derriford hospital introduced the use of collagenase injections for the treatment of Dupuytrens' contracture, and currently remains the only centre to use it in the southwest peninsula.

We present the short term results of our first year of use of the therapy. There was a statistically significant improvement in PEM scores by 1 and 3 months post-treatment (P: 0.0001 and 0.0016 with 95% confidence).

Full correction was obtained in 81% of all MCPJ contractures included in the analysis. Success with PIPJ contractures was more limited, however there was still an average correction of 30 degrees achieved.

Complications were limited to skin tears, all of which healed at subsequent follow-up, and 2 failures of therapy. We will continue to use this therapy and as experience and expertise build we hope we can improve our outcomes further.

Pain is a common presenting symptom of patients with shoulder conditions, yet there has been little work done to accurately describe its distribution and nature.

We studied all patients attending the Royal Devon and Exeter Hospital shoulder clinic from August 2012 – 2013. Patients completed a questionnaire detailing their Oxford Shoulder Score and a validated neuropathic pain questionnaire. Patients were given diagrams to draw on their perceived location of pain or abnormal sensation.

We analysed all patients with frozen shoulder (48), osteoarthritis (37) and rotator cuff arthropathy (17).

We found that neuropathic pain is common in patients with shoulder conditions identified in 39% of OA patients, 42% with rotator cuff arthropathy and 57% with frozen shoulder. Pain outside the shoulder was reported in over 50% of patients, commonly the forearm, hand, neck and chest. Frozen shoulder was especially associated with pain outside of the shoulder with 39% describing symptoms in the neck or chest, 21% into the forearm and 18% into the hand. Interestingly, neuropathic pain radiating down the arm was not described in the rotator cuff arthropathy group.

The high prevalence of neuropathic symptoms and pain felt outside the shoulder aids diagnosis and more accurately identifies these conditions.

The incidence of frozen shoulder (FS) as a complication of simple arthroscopic shoulder surgery has yet to be defined. A single-surgeon case series of patients undergoing arthroscopic subacromial decompression (ASD) or ASD with arthroscopic acromioclavicular joint (ACJ) excision was analysed to establish FS rate, this cohort was then compared to a matched group of primary FS patients.

Retrospective analysis of 200 consecutive cases was undertaken. All procedures listed, performed and reviewed by the senior author. 96 underwent ASD and 104 underwent ASD and ACJ excision. 6-months follow-up minimum.

Incidence of frozen shoulder was 5.21% (ASD) and 5.71% (ASD+ACJ excision). Mean age was 52.3 years (95% CI: 47.4 to 57.2) of the patients that developed FS, compared to 57.2 years (95% CI: 55.2 to 59.2) in the patients who did not and 52 years (95% CI: 50.7 to 53.3) in the primary FS cohort (n=136). 9.1% of post-operative FS were diabetic compared to 17.1% of primary FS. 63.6% were female in the post-operative FS group, 47.1% in the primary FS group.

Our results suggest that the risk of FS following simple arthroscopic procedures is 5%, with no increased risk if the ACJ is also excised.

This cohort has the same average age as a primary FS. There is a trend toward female sex and diabetes does not increase the risk.

There are many types of arthroplasties for the 1st MTPJ, but still the treatment of advance Hallux rigidus remains controversial. In this study we are reporting the outcome of the North Star hemicap at 6 months.

A series of patients under the care of a single surgeon were followed using the Manchester - Oxford Foot Questionnaire (MOXFQ) at 6months post operation, and a satisfaction question was asked. The operations were between August 2011 and August 2013. A total of forty five arthroplasties were implanted in 44 patients. Thirty four of them were female and 9 were male. The average age was 56 years (range 37–77 years).

Twenty six out of them (59%) needed an MUA + a local anaesthetic and steroid injection of the prosthetic joint at 2 to 14 months (average 6 months) post implantation. In these patients the MOXFQ was filled at 6months post the MUA and injection. Four of them were left out of the study because they were less than 6months post MUA. One patient had his implant removed and changed to fusion at his request at 14 months post implantation.

Forty one patients were satisfied and would recommend the operation, 2 were disappointed with the degree of movement but would still recommend the operation and one had it revised to fusion. The average MOXFQ was 12/64. In conclusion, high percentage of patients needed a second operation, but the scores are reasonably low and almost all patients would recommend it. Further follow up of these patients is needed for at least 5years but the early results are showing it to be a good alternative for fusion.

The aim of this study is to use a defined population of patients with meningococcal septicaemia to calculate the incidence of orthopaedic complications.

Medical records and radiographs were analyzed retrospectively for all patients admitted to the Paediatric Intensive Care Unit (PICU) of the Bristol Royal Hospital for Children from 01/01/2001 to 31/12/2012 with meningococcal septicaemia.

Of the 130 patients with meningococcal septicaemia alive at discharge, 10 developed orthopaedic sequelae, representing an overall incidence in this patient population of 7.7%.

9 patients required an amputation, mostly in the lower limb, 16/22 (72.7%). 48 growth plate abnormalities were identified in 8 patients. 39 (81.3%) The most commonly affected was the distal tibia (38.5%). 10 ankles were identified as having a varus malalignment. 6 patients had documented leg length discrepancy

Using a clearly defined denominator this study has identified an incidence of orthopaedic sequelae following meningococcal septicaemia of 7.7%.

The National Institute for Clinical Excellence (NICE) suggested that the incidence of growth disturbance is approximately 3%.

This study highlights the underestimation of orthopaedic complications following meningococcal septicaemia. Close follow up of at risk patients should be considered to reduce the potential impact of these debilitating injuries.

Paley et al developed a mathematical model to predict height, using age, sex and current height. His predictions were based on growth charts from epidemiological databases, and then validated using 52 children. We looked at a recent large, local database, to assess whether the height multiplier is a reliable tool that can be used in clinical practice.

The Avon Longitudinal Study of Parents and Children of the 90s (ALSPAC) is a population based cohort study of 14, 000 contemporary British families. 5363 children had final height measured with an average of 10.5 additional height measurements. The height multiplier equation was defined as height at specific age divided by height at skeletal maturity.

No significant difference was observed between the mean results from Paley et al and the ALSPAC data. There was a significant range of results in the ALSPAC data, with a standard deviation of the multiplier of 0.08 for ages 7–15.

This large population study shows no significant difference between the historical databases Paley used and the more current European databases. The large range of results shown by the ALSPAC cast doubt on the clinical usefulness of individual results.

Predictions of lower limb growth are based upon historical data, collected from patients who had coexistent poliomyelitis. By utilising standardised longitudinal prospective European data, our objective was to generate superior estimates for the age and rate at which lower limb skeletal maturity is reached; thus improving the timing of epiphysiodesis, for the management of leg length discrepancy.

The Avon Longitudinal Study of Parents and Children of the 90s (ALSPAC) is a longitudinal cohort study of children recruited antenatally 2. Using a previously validated Multiplier Method, a sequence of leg length multipliers were calculated for each child.

15,458 individuals were recruited to the ALSPAC study; and of those whose growth was measured, 52% were boys and 48% girls, each with an average of eight recording episodes. 25,828 leg length multiplier (LLM) values were calculated with final recordings taken at a mean age of 15.5 years.

From this data, the age at which girls reach skeletal maturity (LLM=1) is 11 months later than previously calculated and for boys nearly 9 months earlier. With nearly 4000 more children recruited in this cohort than preceding studies, this study brings increased power to future leg length calculations.

Opening wedge high tibial osteotomy (OWHTO) is a treatment option for medial compartment osteoarthritis of the knee in the young active adult. Limited evidence exists in the literature regarding return to activities following OWHTO.

We performed a retrospective study of local patients who underwent OWHTO from 2005 – 2012 assessing post-operative return to sporting function. Patients with additional knee pathology, surgery or alternative issues affecting activity were excluded.

110 patients met inclusion criteria, 75 were successfully contacted.

Mean improvement in pain score = 4.8/10 (95%CI 4.2 to 5.4, p<0.01). Mean pre-operative KOS-SAS score = 0.5/2, mean post-operative KOS-SAS score = 1.1/2, mean change in KOS-SAS score following OWHTO = 0.6 (95% CI 0.5 to 0.7, p<0.01). Mean pre-morbid Tegner score = 5.9/10, pre-operative = 2.7/10, post-operative = 4.2/10. Mean change in Tegner score following OWHTO = 1.5 (95% CI 1 to 1.9, p<0.01). Following OWHTO 25% of patients achieved pre-morbid Tegner scores. Patient BMI, age, type of implant or graft used had no significant effect on outcome.

OWHTO can temporarily improve pain, activity and sporting levels in young patients with isolated medial compartment knee OA. Return to pre-morbid activity levels and even high level sports function is possible although not the norm.

Limited literature exists providing comprehensive assessment of complications following opening wedge high tibial osteotomy (OWHTO). We performed a retrospective study of local patients who underwent OWHTO for isolated medial compartment knee osteoarthritis from 1997–2013.

One hundred and fifteen patients met inclusion criteria. Mean follow-up = 8.4years. Mean age = 47 (range 32–62). Mean BMI = 29.1 (range 20.3–40.2). Implants used included Tomofix (72%), Puddu plate (21%) and Orthofix (7%) (no significant differences in age/ sex/ BMI). Wedge defects were filled with autologous graft (30%), Chronos (35%) or left empty (35%).

Five year survival rate (conversion to arthroplasty) = 80%. Overall complication rate = 31%. 25% of patients suffered 36 complications including minor wound infections (9.6%), major wound infections (3.5%), metalwork irritation necessitating plate removal (7%), non-union requiring revision (4.3%), vascular injury (1.7%), compartment syndrome (0.9%), and other minor complications (4%). No thromboembolic complications were observed.

A higher BMI (mean 34.2) was apparent in those patients suffering complications than those not (mean 26.9). No significant differences existed in complication rates relative to implant type, type of bone graft used or patient age at surgery.

Complications following OWHTO appear higher than previously reported in the literature; serious complications appear rare.

Derriford Hospital gained Major Trauma Centre (MTC) status in April 2012, this led to a significant increase in the trauma case load. Our aim was to review registrar exposure to theatre and clinic in the elective and trauma setting. This was then compared to audits performed pre-MTC status and shortly following MTC changes to see if training standards were being maintained. Improvements in registrar rota planning were made following the previous assessment of training. Training was assessed with respect to national recommendations for registrar training.

Data was collected for 8 weeks in February and March 2014 for all 12 registrars, and cross-referenced with the on-call and daily rota. The data was divided into training and non -training registrars

Elective exposure had improved in both theatres and clinic along with trauma theatre exposure whilst fracture clinic exposure had reduced since the previous audit. The reduction may be a result of the on-call registrar no longer being present in fracture clinic when on-call in compliance with MTC guidance.

Rota management requires a fine balance between service and training commitments. Recent improvements to the management of the registrar rota appear to provide satisfactory training despite the pressures of MTC changes at Derriford Hospital.

Quality Improvement (QI) is of increasing importance with its inclusion on training curricula and requirement for it in revalidation. Junior Doctors are a valuable, yet under utilised resource for NHS Trusts in patient safety/Quality Improvement activity.

A Trainee led QI Academy, supported and administered by Medical Education was launched in our Trust. It offered education on Leadership and Management and support for projects from the Trust Service and Development teams. The QI Academy launch evening attracted over 60 Trainees and 17 QI projects were adopted. Subsequently a further 9 projects have been started and a number published in peer reviewed journals and presented internationally.

The Academy was an attractive and supportive method of engaging new groups of doctors. QI is not as constrained as simple audit, and as such, engaging trainees has proven to be easier. Collaboration between a Core Faculty, Trainees and Trust Management ensured adequate and sustainable support for all projects, avoided duplication and fostered a closer relationship. We highly recommend Trust support of QI in junior doctors through Medical Education. Trusts benefit from improvements in patient care and quality whilst trainees learn valuable skills and benefit from presentations and publications.

Time at the surgical ‘coal-face’ has been reduced by introduction of the European Working Time Directive (EWTD) significantly impacting training opportunity. Our null hypothesis was that duration of surgery is significantly longer if a trainee were performing the operation despite supervision or level of trainee experience.

Cemented hip hemiarthroplasty was chosen as our index procedure as complexity is largely comparable between cases. 461 patients were identified on the hospital trauma database. Data were augmented by information regarding level of surgeon, assistant and time of surgery from the hospital theatre database.

There was no significant difference in registrar and consultant operative times, mean time 69 and 72 minutes respectively. SHOs were significantly slower (mean 80 minutes, p=0.0006). Junior (ST5 or less) registrars were significantly slower (mean 81minutes, p=0.0002) whereas senior registrars were not. Supervision level had no effect on duration of senior registrar operations but when junior registrars were consultant supervised they were not significantly slower (mean 75 minutes, p=0.09).

Supervised operating therefore reduces time variability and should be promoted within a climate of training. Increase in mean operative time in registrars and SHOs is insignificant within a day's operating and is unlikely to lead to cancellations of cases.

The correct prescription of antibiotics for in-patients is paramount to patient safety. Trust policy states that all in-patients on antibiotics must have a start date, duration, and indication for antibiotics documented on the drug-card. On a single day all drug-cards were reviewed assessing whether documentation was in line with policy. In the initial audit, 28 antibiotic courses were prescribed; of these courses only 15 (53.5%) had an indication documented and 15 (53.5%) had a review/stop date documented.

A monthly league table, coined ‘The Champions League’, was created. This named individuals who had correctly or incorrectly prescribed antibiotics, following identification in the monthly audit. It was published monthly and displayed in the doctors' office, on wards and circulated to all Consultants. After two published league tables, 19 antibiotic courses were prescribed. Indication was documented in 18 (94.7%) and 16 (84.2%) had the review date documented. This improvement has continued to the present day.

Prescribing standards appear to have improved with the use of this novel motivational tool. The competitive nature of surgical trainees has led to the Champions League becoming a talking point. Top placed doctors are rewarded with Premiership rugby tickets and those who consistently underperform are sensitively offered remedial instruction.

Diagnosis of complex regional pain syndrome (CRPS) can be challenging. We explore the role of fracture clinic in diagnosis and management with a closed-loop audit of new guidelines.

We retrospectively reviewed patients with CRPS over 3.5 years. We determined the delay from injury to commencement of treatment and monitored symptoms. New guidelines were introduced to fracture clinic in January 2013. The Budapest Criteria aids diagnosis. GAD-7 and PHQ-9 patient questionnaires grade symptoms. Orthopaedic surgeons prescribe nortriptylline or pregabalin, refer to physiotherapy and review patients after six weeks. We re-audited prospectively after implementing these guidelines.

The first audit cycle found 11 patients in 3.5 years. The mean delay to anti-neuropathic medication from injury was 4.7 months. Two patients required psychotherapy, one intravenous pamidronate, three inpatient physiotherapy under nerve blocks and two spinal cord stimulators. After implementing guidelines, there were 14 patients with CRPS in 9 months. All but two patients received anti-neuropathic medication on the day of diagnosis. All patients treated appropriately improved markedly within 4–12 weeks. No patients required escalation of treatment.

Our guidelines increased pick-up rates of CRPS, diagnoses were made earlier and treatment started sooner. Physiotherapy modalities remained varied, however, early anti-neuropathic treatment led to a rapid improvement in all cases.

Surfing is a popular UK water-sport. Recommendations for protective gear are based on studies abroad from trauma from large waves and reef breaks which may not be relevant in the UK. This study assesses the aetiology of UK surfing injuries in order to assist treatment and provide formative recommendations on protective equipment.

Data was collected from UK surf clubs via an online survey. 130 individuals reported 335 injuries. M:F ratio 85:45, median age 28 (range 17–65). Head injuries were the most common (24%) followed by foot and ankle (19%). Surfers collided most often with their own boards (31%) followed by rocks/coral (15%), the sea (11%) and other surf boards (10%). Lacerations were the commonest injury (31%); followed by bruises/ black-eyes (24%) and joint/ligament sprains (15%). Concussions (5%), fractures (3%) and teeth injuries (1%) were rare. Less than 1/3 of all injuries required professional medical attention, 2 required operative intervention.

Surfing injuries in the UK are common but usually minor. Serious head injuries (fractures and concussions) are rare. There is insufficient evidence to warrant the routine use of protective helmets whilst surfing in the UK, although protective head and foot gear may be considered when surfing the rarer reef/ rock breaks.

Stand-up paddle-boarding (SUP) is an increasingly popular water sport. To our knowledge no published data exists regarding injuries sustained whilst participating in this new sport. This study investigates the frequency, pattern, and mechanism of SUP injuries.

Data was collected from UK SUP and surfing clubs via an online survey. Completed surveys were obtained from 31 paddle-boarders (M:F 25:6, median age 27, range 21–65) reporting 18 injuries and 130 surfers reporting 4 SUP-related injuries.

50% of paddle-boarders reported an injury. All SUP injuries were sustained when surfing waves, rather than paddling on calm water. Sprains accounted for 50%, lacerations 22%, contusions 17% and fractures 5%. 78% of injuries were to the lower extremity, and 17% to the head and neck. 17% sustained recurrent twisting injuries, two suffering recurrent knee injuries and one suffering recurrent ankle injuries, resulting in sprains. 17% of injuries resulted from contact with one's own paddle-board, 17% from another paddle-board, and 5% from the sea floor. Despite surfer concerns regarding paddle-board mass and control, paddle-board related injuries only accounted for 1% of the 335 injuries reported by surfers.

SUP is relatively safe in calm water conditions, with a similar injury pattern to surfers when used in waves.
