The aim of this study was to investigate the use of large diameter head THR to treat fractured neck of femur, and to demonstrate if this conferred greater stability.

Forty-six (46) independent, mentally alert patients with displaced intracapsular fractures underwent THR. Mean age was 72.1 years. Outcome measures were dislocation, reoperation/ revision rate, Oxford hip score (OHS), Euroqol (EQ-5D) and residential status. Data was collected prospectively, with review being carried out at 3 months and 1 year.

At mean follow-up (12.5 months) there were no dislocations. Reoperation, revision and infection rate were all 0%. Two patients died (4.3%). Mean pre-injury and postoperative OHS were 12.1 and 17.9 respectively. Mean pre-injury and postoperative EQ-5D index scores were 0.97 and 0.83 respectively. Mean postoperative walking distance was 2.5 miles. There were no changes in residential status.

This is the first published series utilizing 36-mm diameter metal-on-metal THR for the treatment of fractured neck of femur. We have demonstrated that it affords patients excellent stability with no recorded dislocations.

It has been suggested that recent reduction in hours worked by orthopaedic trainees in the UK may result in less exposure to operative procedures.

To examine this possible change, operative data showing the participation of specialist registrars in orthopaedic trauma cases were examined over 6-month periods in 2002 and 2007. Operations specifically examined included dynamic hip screw, hip hemiarthroplasty, manipulation under anaesthetic, ankle fracture fixation, and tension band wiring. A traditional on-call system was used throughout but the number of working hours was reduced.

Analysing individual operations, the results demonstrated a general trend for trainees to perform fewer procedures in the 2007 group, but this difference was not statistically significant. Level of consultant supervision was not significantly different except for hip hemiarthroplasty, which was higher in 2007. When considering all operations together, there was a significant decrease in the number of procedures performed by trainees in 2007, and although there was a trend for more supervision, this was not significant. Trainees were present for a significantly lower proportion of procedures in 2007 than 2002.

We conclude that it appears operative experience in orthopaedic trainees may be less than 5 years ago and this may be associated decreased attendance in theatre.

Immobilisation is known to be a risk factor for thromboembolic events and the management of ankle fractures often involves immobilisation of the fracture in a below knee cast. Recent literature has found a 5% rate of subclinical deep vein thrombosis (DVT) and suggested thromboembolic prophylaxis is not required.

This study involved all adult patients with isolated ankle fractures presenting to a district general hospital orthopaedic department over a 6 month period. This included patients undergoing internal fixation as well as non-operative management. A 3 to 7 month follow-up was performed to assess the incidence of clinical DVT or pulmonary embolism (PE) proven using Doppler imaging, venogram, and computed tomography pulmonary angiography. 119 patients met the entry criteria and, of these, 3 patients developed DVT and 2 patients presented with pulmonary embolus. 15 patients in the study were taking aspirin (75–300 mg daily) during their cast immobilisation and 1 patient was taking warfarin. None of these patients developed a thromboembolic complication. 4.8% of patients not taking aspirin or warfarin experienced a thromboembolic complication.

This study demonstrates a relatively high incidence of symptomatic thromboembolism following ankle fractures in the absence of prophylaxis. Previous studies have found aspirin to be an effective method of prophylaxis following hip fractures and total hip arthroplasty. We recommend that thromboembolism prophylaxis is necessary following ankle fractures and suggest that aspirin may be an economical option. Larger studies are needed to evaluate the role of aspirin in this setting.

Dislocation is a major concern following total hip replacement (THR) for fractured neck of femur. The aim of this prospective study was to investigate the use of large diameter femoral head uncemented THR to treat fractured neck of femur, and to demonstrate if the improved stability seen in previous clinical situations with these designs, can be used to benefit this difficult subgroup of patients that are particularly prone to dislocation.

Forty-six consecutive independent, active and mentally alert patients with displaced intracapsular fractured neck of femur underwent large diameter head uncemented THR. The mean age of patients was 72.1 years. The outcome measures used were the dislocation rate, reoperation and revision rate, Oxford hip score (OHS), Euroqol (EQ-5D) and residential status.

Clinical and radiological data were available on all 46 patients. At a mean follow-up of 12.5 months there were no dislocations. The reoperation, revision and infection rate were all 0%. Two patients died (4.3%) from unrelated causes. Mean pre- and postoperative OHS were 12.1 and 17.9 respectively. The mean pre- and postoperative EQ-5D index scores were 0.97 and 0.83 respectively. The mean postoperative walking distance was 2.5 miles and there were no changes in residential status.

This is the first published series utilising a 36-mm diameter metal-on-metal THR for the treatment of fractured neck of femur in mobile, independent patients. We have demonstrated that it affords patients excellent stability with no recorded dislocations.

Aim: To compare the outcomes of autologous versus no drainage in patients undergoing primary hip and knee arthroplasty.

Methods: Retrospective review of patients undergoing primary total hip or knee arthroplasty within our unit was carried out. There were 4 groups, each consisting of 20 patients. These were; total hip arthroplasty with and without the use of autologous drains, and total knee arthroplasty with and without the use of autologous drains. Outcome measures were- requirement for homologous (banked) blood, post-operative drop in haemoglobin and length of stay in hospital.

Results: For the knee arthroplasty groups, the homologous transfusion rate was 25% in non-drain patients compared with 5% in patients with drains. The average drop in Hb was 3.3 g/dl in the no-drain group compared with 2.7 in the drain group. The average length of stay was 6.35 days in the no-drain group compared with 6.75 days in the drain group. For the hip arthroplasty groups, the homologous transfusion rate was 10% in the non-drain group compared with 15% in the drain group. The average drop in Hb was 3.9 in the no drain group compared with 3.3 in the drain group. The average length of stay was 6.8 days in the no-drain group compared with 6.9 days in the drain group.

Conclusion: These results demonstrate improvements in the transfusion requirements as well as post-operative Hb drop in knee arthroplasty, but not hip arthroplasty when autologous re-transfusion drains were used. The length of stay was not significantly altered by the usage of drains. Based on these results, we would therefore recommend the use of autologous drains in primary total knee arthroplasty but not in primary total hip arthroplasty.

Aim: To determine the effects of the different types of headgear on bacterial shedding in laminar flow theatres.

Material and Methods: Sham experiments were carried out using standard theatre clothing, sterile gowns and face masks with visors. Three experimental groups were utilised; no headgear (control), surgeons hoods or fabric balaclavas (known colloquially as “chicken hats”). The sham experiments consisted of two surgeons, scrubbed and gowned, both wearing the same headgear, talking and moving hands for 30 minutes over a sterile mock operating field. 5 bacterial plates were placed on the sterile sheets to capture shed bacteria. An additional 5 plates were placed above head height in the laminar flow enclosure. An air sampler was positioned within the laminar flow and set off for the middle 5 mins of the experiment. Plates were then incubated for 48hrs at 37oC and the number of colony forming units at head and waist height as well as in the air sampler were counted. Each experiment was repeated 5 times.

Results: The bacterial shedding rate at waist height was 0.2 CFUs/plate (314 CFUs/m2/hr) for the control experiment, 0 CFUs/plate (0 CFUs/m2/hr) for the surgeons hoods and 0.08 CFUs/plate (126 CFUs/m2/hr) for the fabric balaclavas.

Conclusion: These experiments show very low bacterial shedding rates with standard clothing and headgear in laminar flow theatres. Although these results demonstrate worse bacterial shedding with fabric balaclavas (which contradicts conventional thinking), the low rate of shedding rates means the results are not statistically significant. It therefore raises the question as to whether we should be using the more expensive fabric balaclavas without proven benefit, and the possibility of increased bacterial shedding.

The use of arthroplasty registers was initiated by Sweden in 1979. The practice has been adopted globally as best practice for recording the outcome of joint replacement surgery and for identifying early problems. The Trent and Wales Arthroplasty Audit Group began in 1990 and have recently produced outcome results. We have analysed the short-term outcomes of arthroplasty procedures at a DGH in order to assess comparability to this “gold-standard”.

In 2004, 231 primary arthroplasties were performed, by the two senior authors, at Musgrove Park Hospital (149 THR, 82 TKR). There was an overall complication rate of 8.7%. There was 1 periprosthetic infection in a THR that required revision (0.043%). 9 patients developed wound complications, principally superficial infections and haematoma formation. 2 patients, both THR developed, thromboembolic complications, one DVT and one pulmonary embolus. There was one periprosthetic fracture around a THR. The dislocation rate for THR was 3.35% (5/149). 3 of these were performed through a posterior approach and 2 through an anterolateral. 3 have required revision surgery.

We have demonstrated comparable results following joint arthroplasty to published teaching hospital series. We have shown that adequate infrastructure can exist in smaller units to accurately record outcome data following arthroplasty surgery.
