We conducted a community survey of the prevalence, health impact and location of chronic pain. We explored the relationship and patterns of chronic pain that commonly occur, with a view to understanding why some treatment approaches may be more appropriate than others for particular patterns of pain.

In 2002, 2504 randomly sampled patients from 16 General Practices in the South East of England responded to a postal questionnaire about chronic pain. Those with chronic pain completed a pain drawing. We calculated descriptive statistics, relative risk and correlations to identify the associations and risks of having linked pain.

The highest prevalences were low back (23%), shoulder (20%) and knee (18%) pain. The number of pain sites experienced was age related in men but less so in women. Lower body pain was more age related than upper body and non musculoskeletal pain. Multi site pain was more common than single site pain. Of those with low back, knee and shoulder pain, 14%, 4.5 % and 1.9% had only low back, knee and shoulder pain respectively. Correlations and minimum spanning trees showed that chronic upper and lower body pain are distinct and axial pain link the two.

Chronic pain is more likely to be multi site, especially at middle age. Research, physical treatments and approaches to managing chronic pain are often site specific, therefore specialising treatment to one area eg low back pain often negates the bigger issue. This may help explain the self perpetuating problem of persistent chronic pain.

A prospective audit was conducted at an associate teaching hospital in the south west to assess the outcome of operative treatment of ankle fractures of all patients over the age of 50 years in the last 2 years.

The aim of the study was to assess whether change in timing of surgery for ankle factures in accordance with the CEPOD guidelines has affected the outcome in terms of early complications. This is a follow up paper to the one published from this institution in 1994 (data 1988 to 1989). Since then the CEPOD rules have led to changes in theatre protocols, so very few ankles are fixed out of hours. Over this period there has been the emergence of MRSA which was not a problem in the 1990s.

We retrospectively reviewed the notes and x-rays for 107 consecutive patients older than 50 years who had their ankles fixed over a period of 2 years spanning 2003 to 2004. Our series had 12.1% incidence of clinical infections, 15.9% delayed wound healing as compared to 1.8% and 5.2% in previous publication from this institution. In our study 17.7% of ankles were fixed within 24 hours as opposed to 84.2 % in the previous paper. All of the infected wounds (100%) occurred in patients who had their operations 48hrs or more post injury. We also came across 2 cases of MRSA infection in our series.

We are concerned that changes in CEPOD rules as well as new hospital practice has resulted in delays in time to fixation. This seems to be the only variable to result in increased infection rates and delays in wound healing leading to increase in hospital stay and reoperations.

Purpose: Methods: Evaluation of the results of arthroscopic ankle arthrodesis, performed in 49 consecutive patients (52 ankles), with disabling ankle arthritis, between 08/1998 and 12/2004. Thirty ankles had no significant deformity (group A), whereas 22 ankles had a varus or valgus deformity greater than 10° (mean 21.7°, max 45°) (group B). Mean age in groups A and B was 49.7 and 57.5 years respectively (p=0.15). The primary diagnosis in groups A and B was post-traumatic arthritis in 66% and 27% and idiopathic osteoarthritis in 17% and 59%, respectively. Average hospital stay was 3.63 and 3.68 days in groups A and B respectively (p=0.96). Postoperative treatment included ankle immobilization for 3 months. Progressive weight-bearing was initiated at two weeks. Mean follow-up was 14.9 months (range 6–60).

Results: No infections or neurovascular problems occurred. Fusion occurred in 29/30 cases in group A at an average time of 11.52±5.2 weeks and in 21/22 patients at 11.67±2.3 weeks in group B (p=0.89). Not planned surgical procedures were required in eight cases (15.4%). Symptomatic arthritis from the adjacent joints developed in three cases during the follow-up period. The arthrodesis position angle measured in the sagittal plane from the lateral post-operative plane film averaged 105°±3° and 103°±6° in groups A and B respectively (p=0.27). The outcome in groups A and B was graded as very good in 73% and 72.7%, fair in 23% and 22.7% and poor in one case in each group, respectively (p=0.26).

Conclusions: The arthroscopic technique offers a high fusion rate, decreased time to fusion, short hospital stay and absence of limb-threatening complications. Deformity correction can be attempted with equally good results.

Introduction We report the experience of a district general hospital foot and ankle service, in performing a modified excision arthroplasty and tendon transfer to the metatarsophalangeal (MTP) joints of the lesser toes in both rheumatoid and non-rheumatoid patients. The procedure was carried out on 114 toes, in 58 feet of 55 patients over a 5-year period.

Background Historically, partial proximal phalangectomy was complicated by recurrence of the extension deformity. Stainsby (1990) described a technique of 7/8ths phalangectomy, repositioning of the plantar plate, extensor to flexor attachment and K-wire stabilisation to treat dislocated MTP joints of the lesser toes. However, it is recognised that the use of K-wires can be complicated by infection or premature removal. Angel reported the re-routing of the extensor tendon through a drill hole in the metatarsal head for MTP joint instability; this technique was attributed to Nigel Cobb. We have utilised the Stainsby technique and combined it with a Cobb tendon transfer to impart immediate stability to the toe, allowing K-wire fixation to be discarded.

Technique Following a percutaneous proximal extensor tenotomy, a radical partial proximal phalangectomy (via a dorsal incision) reduces a dislocated MTP joint and the plantar plate is repositioned beneath a mobilised metatarsal head. A drill hole is then placed in the metatarsal head and the extensor tendon is re-routed from a plantar to dorsal direction. This maintains the reduction of the toe and provides interposition between the cut end of the proximal phalanx and the metatarsal head.

Conclusion We believe that this modified combined technique is a reproducible alternative to the Stainsby procedure but, in addition, provides immediate stability of the MTP joint without the need for K-wire fixation.

Introduction The Buechel-Pappas Total Ankle Replacement (BP TAR) has been used in Cornwall since 1991. The early results were presented to the Foot Society in 1997. The only published long term results of this pros-thesis are from the designer’s unit.

Method We present the clinical and radiological outcome of a prospective series of 22 BP TARs implanted in 19 patients with a mean follow-up of 9 years (range 6–13). The primary diagnosis was rheumatoid arthritis (RA) in 11 and osteoarthritis in eight patients. Twelve patients were female. Mean patient age was 64 years (range 39–81). Patients were reviewed at yearly intervals. None were lost to follow-up.

Results At the time of review, four patients (six ankles) had died between 12 and 69 months post-operatively of unrelated causes with their prostheses in situ. One patient had a below knee amputation for chronic venous ulceration, 11 years after a BP TAR which was functioning well. One patient with severe RA had the implant removed at 8 weeks for deep infection. A second patient with RA had the TAR revised to a tibiotalocalcaneal fusion 59 months post-operatively for talar avascular necrosis. One patient has pain from impingement and another patient with RA has intermittent pain at 8 years following TAR. Every other implant remains asymptomatic. The New Jersey LCS ankle assessment scores increased from a mean of 35 pre-operatively to 82 post-operatively. The increases were largely due to pain relief and improved function with the pre-operative range of motion being preserved. These scores have been maintained in the long term. No surviving implant is radiologically loose.

Conclusion Our results suggest that the BP TAR offers good clinical and radiological long-term results to patients with often disabling ankle arthritis.

Background – Chronic musculoskeletal pain (CMP) is a major health problem, for which patients consult a wide range of practitioners often with little success. This may be due to the sometimes different explanatory models for pain held by patients and practitioners. Gaining an understanding of these models may improve care. An area of conflict may be the identification and management of the psychological aspects of pain.

Purpose – To explore patients’ and practitioners’ beliefs and expectations of treatment for CMP, in relation to the identification and management of the psychological aspects to pain.

Method – In-depth qualitative interview study of 24 practitioners (osteopaths, chiropractors, physiotherapists and GPs) and 24 patients with CMP which explored their beliefs about causation and treatment of CMP. Maximum variety purposive samples of both groups were selected. All interviews were audio-taped and transcribed for analysis. Data was analysed using FRAMEWORK.

Results – Patients and practitioners believed that stress influenced pain perception, however some patients believed that stress could also cause pain. In terms of the consultation, practitioners felt pressure from patients to provide them with emotional / psychological support which on the whole they felt ill-equipped to provide. Patients operated with a physical model of illness and felt dismissed if practitioners focused too much attention on the psychological aspects of their pain.

Conclusion– Practitioners expressed confusion over what they were expected to provide patients in terms of psychological support. They also expressed a need for training in the management of behavioural / psychological aspects to pain. Patients may also require education to increase their awareness of the psychological aspects to their pain.

Background – Patients with unexplained chronic musculoskeletal pain (CMP) can be difficult to help, consulting a range of services before consulting specialist pain services. Conflicts between the explanatory models for illness used by patients and health professionals might contribute to this complex ‘career path’, increasing the likelihood of unsatisfactory outcomes for both practitioners and patients.

Purpose – To explore the understanding of the experiences of diagnosis and management amongst patients who attended a specialist musculoskeletal pain clinic.

Method – Potential participants were sent a postal questionnaire 6–20 months after their first clinic attendance. Data was collected on pain presence, severity and location, health related quality of life and care seeking behaviour. Questionnaire data was used to inform combined purposive and theoretical sampling. In-depth interviews were conducted which probed participants’ understanding of their CMP and its management. Data was analysed using FRAMEWORK.

Results – 15 patients were interviewed. Four main themes were identified; a) spoiled identity – were pain limited patients activities so much that this affected their sense of self; b)Diminishing faith in medicine – Patients were disappointed with aspects of their care seeking experience; c) Making sense of pain – Patients made sense of their pain by locating their pain within the context of their lives; d) Learning to live with the pain – An issue for all patients was whether or not their pain would go.

Conclusion – Developing, implementing and evaluating approaches to address patients’ spoiled identity might allow us to improve patient centred outcomes in CMP.

Background – Chronic musculoskeletal pain (CMP) is a major health problem treated by a wide range of health professionals. Complementary therapies are likely to become more readily available on the NHS. Therefore a greater understanding of current service use may be helpful in ensuring appropriate targeting of services in the future.

Purpose – To describe current service use for CMP in a UK representative population. To examine predictors of CMP use.

Methods – Population questionnaire survey to 4100 patients registered with 17 Medical Research Council General Practice Research Framework general practices. The questionnaire collected data on demographics, presence of pain, pain location and severity, health related quality of life (HRQOL), care seeking and beliefs about pain. Univariate and multivariate analyses was undertaken to examine predictors of care seeking.

Results – Response rate of 61% of whom 47% reported CMP use. 77% consulted for their CMP; 60% mainstream medicine only, 17% mainstream and / or complementary and 22% no-one.

Patients who consulted complementary practitioners were more likely to be female, to be psychologically distressed, to work, to have left school aged over 16 and to have severe pain (p< 0.05 in all cases). Working was independently associated with consulting a complementary practitioner (Exp (B) = 2.0, p=0.00)

Conclusion – Complementary therapies are currently only available to those patients who can afford them. If such therapies become available on the NHS it may be important to provide patients and health professionals with appropriate information to inform their choices about these care options.

Background: Chronic musculoskeletal pain (CMP) is a major health problem for the individual and the NHS. It is important to examine the prevalence of and factors associated with it, to identify unmet need and inform the development of interventions.

Purpose: To describe the prevalence of CMP in a community based sample, overall and by location; To describe the factors associated with presence of CMP.

Methods: Population questionnaire survey to 4100 patients registered with 17 Medical Research Council General Practice Research Framework practices. We collected questionnaire data on demographics, presence and location of pain, pain severity, health related quality of life, care seeking and beliefs about pain. We then did univariate and multivariate analyses to identify factors associated with CMP.

Results: Survey response rate was 61% (2509/4100); mean age 52 years (range 18–101); 56% female. CMP prevalence was 47%. One month period prevalence by area was; Lower back 23%; Knee 19%%; Shoulder 16%; Hip/thigh 14% and Upper back 6%. The majority of sufferers consulted their GP (61%), but a large minority (21%) consulted no-one. Factors associated with presence of CMP were being older, leaving school aged 16 or less, not working, having poorer quality of life and experiencing psychological distress (P< 0.05). In a multivariate analysis no factors were independently associated with presence of CMP.

Conclusion: Results demonstrate the significant burden CMP presents in the community and the need to focus interventions on those individuals who may be more likely to suffer. It may be particularly important to consider the needs of those who have not consulted anyone.

Background: A wide variety of practitioners with different belief systems and approaches treat chronic musculoskeletal pain. In trials of treatments for musculoskeletal pain the focus has tended to be on outcome rather than on understanding the process of care of these treatments. Gaining greater understanding of the process of care in consultations for chronic musculoskeletal pain may shed light on ways to improve patient care, as despite the range of options available many patients are still dissatisfied with their treatment.

Aim: To undertake a systematic review to explore how the beliefs and expectations of patients with chronic musculoskeletal pain and their treating primary and community care practitioners / therapists influence the process of care

Method: A comprehensive search strategy was developed. Databases including MEDLINE, PSYCHINFO, AMED, and MANTIS were searched by two members of the review group working independently. Two members of the group again working independently screened the title and abstract of each reference retrieved for inclusion. Studies were included if they Reported original research

Explored patient’s or practitioners; beliefs and expectations, or both.

Studied patients with chronic musculoskeletal pain, which does not have a known systemic, inflammatory or malignant origin treated in primary or community care.

The full review group resolved disagreements. Full text articles meeting the inclusion criteria will be obtained and coded further into non-randomised studies, randomised studies and qualitative studies. Data abstraction forms will be developed for each type of study. Data abstraction will be undertaken by two members of the group working independently.

Results: 12, 667 articles were identified from the searches of bibliographic databases. At the present time 10 papers have been identified for potential inclusion in the review. The number of full papers to be considered for the review will be reported in this presentation along with the methods for data abstraction and synthesis. This study is ongoing.

Background: Chronic low back pain (CLBP) is a complex health problem often resulting in difficult consultations for both patients and practitioners. Triggers for consultation may include pain severity, impact of pain on health-related quality of life and troublesomeness of pain. Troublesomeness of CLBP may be influenced by patients’ beliefs about their health, such as beliefs about what is acceptable for their age or lifestyle and their perceptions of risk. Therefore, troublesomeness may be a powerful trigger for consultation for CLBP.

Aim: To explore whether troublesomeness of CLBP is associated with consultation.

To determine the most powerful predictors of consultation for CLBP from pain severity, troublesomeness, health related quality of life and psychological distress

Method: Postal questionnaire survey to randomly sampled patients registered with 18 MRC General Practice Research Framework general practices (5400 patients) with two reminders. Questionnaire measures persistent pain (presence and location), pain severity (using the Chronic Pain Grade questionnaire), health related quality of life (EQ5D), psychological distress (GHQ12), troublesomeness of pain on a simple five point Likert scale and patient demographics.

Chi square tests will be undertaken to explore the relationship between troublesomeness of CLBP and consultations for pain in general and with whether consulted mainstream or complementary practitioners. Multiple logistic regression will be undertaken to explore the most powerful predictors of consultation for CLBP.

Results: The survey is ongoing. A full data-set will be available for the presentation. So far 354 questionnaires have been returned, 48% (167/347) of participants report persistent pain of these 62% (104/167) reported at least moderately troublesome CLBP. Of those reporting troublesome CLBP, 74% (76/103) had consulted their GP, 87% (90/103) had consulted other practitioners including physiotherapists, osteopaths and chiropractors, 27% (28/103) had seen a hospital consultant and 17% (18/103) had consulted no one.

Conclusions: These data suggest that troublesomeness is a simple way to improve the ability of epidemiological studies of back pain to contribute to health needs assessment.

Background: Chronic back pain is a complex and costly health problem, treated by a wide range of practitioners, with different belief systems and approaches. Despite the range of options available, many patients appear to be dissatisfied with the treatment that they receive. This may be due to a mismatch between patients’ and practitioners’ beliefs about the cause of the pain and their expectations for treatment.

Objectives: To explore patients’ beliefs about the causes of their chronic back pain and their expectations regarding treatment.

Methods: Group interviews were held with two sample groups of individuals (experiencing moderate and severe chronic pain) to inform a series of qualitative individual interviews with patients and practitioners, exploring beliefs about the causation of chronic pain and expectations for treatment.

Participants were identified from respondents reporting chronic pain in a postal questionnaire survey administered through a local general practice. Participants were allocated to groups according to the severity of their pain, as measured by the Chronic Pain Grade. Those with grades II and I were allocated to group one and those with grades III and IV to group two.

Results: Participants presented sophisticated accounts of their pain and their care seeking. General practitioners were seen as the most appropriate first ‘port of call’, as chronic back pain was viewed as a medical problem requiring a medical solution such as X-rays, referral to hospital specialist and eventually operations. Participants presented to their GP in hope of a medical solution, which was seldom realised. Participants appeared to be resolved to this situation, yet sustained the belief that a different way of communicating their problem to their GP may lead to appropriate action.

Conclusion: There was a marked contrast between the groups on some issues, which will be explored further within this presentation.

We wish to report a technique for the reconstruction of the late presenting Tendo Achilles rupture.

A proximal intra muscular Z lengthening through a separate incision facilitates distal translation of the proximal tendon stump, allowing direct repair distally with minimum tension.

Post operatively, a below knee cast is applied for six weeks, with progressive dorsiflexion at two weekly intervals.

A dorsiflexion restriction splint accompanies early physiotherapy for a further six weeks, with unprotected weight bearing commencing at three months.

There were eleven patients in the study group with an average follow up of 24 months. All tendons united. There were no re-ruptures. Two distal wound breakdowns occurred and one of these healed by secondary intention.

Good single stance power returned in patients with smaller separations but greater calf wasting and weakness was observed in those patients with large separations.

We conclude that this technique can be employed for the reconstruction of late presenting Achilles tendon ruptures, but great care is required with soft tissue dissection distally.

The operative and non-operative treatment options for acute tendo achilles rupture are well documented in the literature. The management of late presenting tendon rupture is usually operative, and can be complicated by acute shortening of the muscle-tendon unit and leave repairs under tension, which may lead to re-rupture. We report the use of the sliding graft technique for reconstruction of late presenting rupture.

A proximal intra muscular Z lengthening through a separate incision facilitates distal translation of the proximal tendon stump, allowing direct repair distally with minimum tension.

Post operatively a below knee cast is applied for six weeks with progressive dorsiflexion at two weekly intervals.

A dorsiflexion restriction splint accompanies early physiotherapy for a further six weeks with unprotected weight bearing commencing at three months.

There were eleven patients in the study group with an average follow up of 13 months. All tendons united. There were no re-ruptures. Two distal wound breakdowns occurred and one of these healed by secondary intention.

Good single stance power returned in patients with smaller separations but greater calf wasting and weakness was observed in those patients with large separations.

We conclude that this technique can be employed for the reconstruction of late presenting tendo achilles ruptures but great care is required with soft tissue dissection distally.

Consideration could be given to deep flexor transfers in the widely separated case.

The aim of our study was to demonstrate the safety of the use of a maximal allowable blood loss formula to reduce the transfusion requirements of elective primary arthroplasty patients.

In the UK, many arthroplasties are performed each year. Many patients will receive blood transfusion post operatively. Often these patients don’t predonate blood, and most units don’t use re-infusion drains. Blood is both costly, and potentially hazardous product to use; we felt it may be beneficial to patients to reduce the unnecessary use of allogenic blood.

We began with a prospective six-month audit, of transfusion requirements of our elective primary arthroplasty patients, establishing our blood use. Our results showed that 66% (58% knees, 73% hips) had at least one unit of blood post operatively, averaging 1.3 units per patient (1.1 knees, 1.5 hips).

Following this, we instituted a new protocol for postoperative blood transfusion. The protocol involved calculation of a maximum allowable blood loss (MABL) the patient could safely lose prior to the need for blood transfusion. This value is based on the patients weight and preoperative haematocrit. Blood loses up to this value would be made up with colloid replacement. When this MABL value is reached the patient has a bedside measurement of their haematocrit. If it has fallen below 0.3 for males and 0.27 for female patients then they are transfused blood, one unit at a time until it is at or above these reference values. As a ‘safety net’ all patients have a formal full blood count on days 1,2, and 3, and are transfused if their Hb is less than 8.5 g/dl.

This protocol was in place for one year (Feb. 2001-Feb. 2002). Our results show, on average a reduction of blood use from 1.3 units to 0.56 units per patient. The percentage transfused was reduced from 66% to 24% (11% knees, 34% hips).

Overall we had a significant reduction of 59% in units of blood transfused to patients following the new protocol. And feel that this method demonstrates a safe system to reduce transfusion requirements.

We describe the histology of a specimen taken from an amputated leg seven months after a 15 cm bone gap in the tibia had been closed by bone transport. Lengthening appeared to have occurred by repeated minor trauma to the bone, with the fractured trabeculae in sufficiently close contact for the repair process to proceed. Osteogenesis did not occur through a cartilage phase, but the fracture gaps were bridged by collagen fibres, around which new bone formed. Microfractures had repaired by primary healing with woven bone and with no microcallus. Small regions of bone were necrotic. Resorption of the necrotic bone and remodelling of the immature bundle and woven bone were still at an early stage, suggesting that complete remodelling in man may take years rather than months.
