Nice guidelines recommend VTE prophylaxis to patients in below knee casts following foot and ankle surgery following risk assessment. The guidelines are controversial and BOFAS recommendations reiterate the risk factors but highlight poor evidence to support these guidelines. Implementation has been variable dependent on interpretation. 58 patients who underwent hindfoot procedures and were immobilised in a cast were identified. These patients were under the care of two consultants, one of whom anticoagulates with daily enoxaparin and one who does not, providing a de facto case-control design. The patients were followed up to identify those who subsequently suffered a DVT or PE, and the clinical circumstances. 2 cases of VTE events were noted in 58 patients undergoing foot and ankle surgery. Both were elective cases managed postoperatively in cast and treated with prophylaxic enoxaparin. Both of these presented to hospital with signs of VTE greater than 6 weeks following surgery after cast removal and discontinuation of enoxaparin. No patients were considered high risk according to NICE guidelines. None of the patients who received no thromboprophylaxis had a clinical DVT. Within our study group we found that VTE thromboprophylaxis does not influence clinically evident VTE rates. Patients who developed VTE were not considered high risk by definition of NICE guidelines but only at increased risk due to their immobility. The VTE events were initiated while the patients were receiving thromboprophylaxis. The effectiveness of the guidelines in predicting patients who would benefit from chemoprophylaxis is questionable from this study. NICE guidelines on VTE thromboprophylaxis have been received with some concerns. Although this investigation studied only a relatively small number of patients, it raises issues about the clinical effectiveness of the guidelines in foot and ankle patients

Introduction. Total contact casting (TCC) is one of the most commonly utilized modalities in the management of diabetic feet. We undertook a retrospective review to determine the prevalence of symptomatic VTE events in patients treated in a weight bearing TCC in our diabetic foot unit, and to formulate guidelines for VTE prophylaxis. Methods. Electronic records were reviewed to identify all patients treated in a TCC between 2014 and 2021. Data collection included patient demographics, comorbidities, period of immobilization in TCC, the incidence of VTE events, and any VTE prophylaxis prescribed during their period in TCC. Results. 549 patients were identified who had at least one episode of TCC. Mean age was 67 years (range 28 to 94 years) and the mean duration in cast was 10.2 weeks (range 0.3–46 weeks). Only 6 patients (1.1%) were prescribed chemical thrombo-prophylaxis during their period in TCC. Mean body mass index (BMI) for these patients was 32.3 (Range 18.4–58.9). Other significant comorbidities: 81% (n-444) of patients had associated cardio-vascular comorbidities; 54 % (n-296) had renal comorbidities including 22% (n-121) having had dialysis and 4.2% (n-23) with renal transplants. Eight of the 549 patients (1.5%) had suffered a VTE event of which only 2 (0.36%) were during the period of immobilization in TCC. One was a symptomatic DVT (0.18%) and the another was an asymptomatic (incidental) finding of pulmonary embolism (PE). There was no mortality related to the VTE episodes. Conclusion. NICE guidelines state that one should “Consider pharmacological VTE prophylaxis for patients with lower limb immobilization”. Our study finds that patients treated in a weight bearing TCC do not require routine pharmacological VTE prophylaxis, in spite of an extended period of lower limb immobilization and significant medical comorbidities

Introduction:. NICE guidelines state that every patient should be assessed for their VTE risk on admission to hospital. The aim of this study was to determine whether currently recommended risk assessment tools (Nygaard, Caprini, NICE and Plymouth) can correctly identify the patients at risk. Methods:. In a consecutive series of over 750 trauma patients treated with cast immobilisation 23 were found to have suffered a VTE. Their notes were retrospectively reviewed to discover how many had been assessed for their VTE risk on admission. Additionally, the 4 most current Risk Assessment Tools were used to retrospectively score the patients for their VTE risk to determine whether they would have been identified as at risk of sVTE, had the RAMs been used at the time. We also identified a matched group of patients in the same cohort who had not suffered a VTE and they were also retrospectively risk assessed. Results:. NICE (2010), Caprini (2001) and Nygaard (2009) identified 100% of the 750 patients as at risk of sVTE but had a specificity of 0% as only 23 went on to develop VTE. The Plymouth Score (2010) was more specific and identified 56.3% patients of the 23 confirmed VTEs as ‘at risk’. However it would not have recommended prophylaxis in the remaining 46.7 & that did in fact go on to developed VTE. Conclusion:. The tools used in this study have no clinical utility in this patient group. Detailed evaluation of the different RAMs is required in order to improve their discriminatory power. A reliance on NICE, Caprini and Nygaard tools would have required all 750 patients in this group to have been treated with thromboprophylaxis and therefore lacked sensitivity. However the Plymouth Score would have failed to recommend thromboprophylaxis in half of the patients who eventually developed VTE

Aims. Malignant tumours of the foot and ankle are rare, but easily missed. NICE guidelines for bone and soft tissue tumours may be less appropriate for the foot and ankle than elsewhere. The purpose of this study was to identify the clinical features and treatment of malignant tumours arising in the foot and ankle to see if guidelines should be modified. Patient and Methods. This was a retrospective review of patients presenting to the Bone and Soft Tissue Tumour Service with a suspected tumour of the foot or ankle. Between March 1998 and July 2009, 132 patients were identified from a prospectively collected database of patients reviewed at a weekly multidisciplinary meeting. Results. Of 132 patients, 43 had benign tumours, 26 malignant tumours and 65 tumour like conditions (eg. ganglions, epidermal cysts, osteophytosis). In the malignant tumour group, the median duration of symptoms prior to presentation was 24 months, with a painful, small but enlarging mass being the most common clinical presentation. In 4 of the 26 cases (12%) unplanned excision had been undertaken prior to referral. Of the 26 malignant tumours, 4 were primary bone tumours (1 Ewing's sarcoma, 1 osteosarcoma and 2 chondrosarcomas) and 22 were soft tissue tumours of which 9 (41%) were synovial sarcomas. In 15 of 26 (58%) of cases the malignant tumour was high grade. In 10 of 26 (39%), amputation was required in order to achieve curative margins and 7 (25%) cases required soft tissue reconstructive surgery following tumour resection. Conclusions. The majority of malignant tumours in the foot and ankle are soft tissue in origin and high grade. Their clinical presentation can make early detection challenging and a high index of suspicion is required. In this review most malignant tumours presented as longstanding, small but enlarging, painful masses. Specific guidelines for investigation and referral may be warranted in addition to the current NICE recommendations

Aims

The Cartiva synthetic cartilage implant (SCI) entered mainstream use in the management of first metatarsophalangeal joint (MTPJ) arthritis following the positive results of large trials in 2016. Limited information is available on the longer-term outcomes of this implant within the literature, particularly when independent from the originator. This single-centre cohort study investigates the efficacy of the Cartiva SCI at up to five years.

Aims

Venous thromboembolism (VTE) is a potential complication of foot and ankle surgery. There is a lack of agreement on contributing risk factors and chemical prophylaxis requirements. The primary outcome of this study was to analyze the 90-day incidence of symptomatic VTE and VTE-related mortality in patients undergoing foot and ankle surgery and Achilles tendon (TA) rupture. Secondary aims were to assess the variation in the provision of chemical prophylaxis and risk factors for VTE.

Aims

To compare the cost-utility of removable brace compared with cast in the management of adult patients with ankle fracture.

Aims

Diabetic foot care is a significant burden on the NHS in England. We have conducted a nationwide survey to determine the current participation of orthopaedic surgeons in diabetic foot care in England.

Diagnostic and operative codes are routinely collected for every patient admitted to hospital in the English NHS. Data on post-operative complications following foot and ankle surgery have not previously been available in large numbers. Data on symptomatic venous thromboembolism events and mortality within 90 days were extracted for patients undergoing fixation of an ankle fracture, first metatarsal osteotomy, hindfoot fusions and total ankle replacement over a period of 42 months. For ankle fracture surgery (45 949 patients), the rates of deep-vein thrombosis (DVT), pulmonary embolism and mortality were 0.12%, 0.17% and 0.37%, respectively. For first metatarsal osteotomy (33 626 patients), DVT, pulmonary embolism and mortality rates were 0.01%, 0.02% and 0.04%, and for hindfoot fusions (7033 patients) the rates were 0.03%, 0.11% and 0.11%, respectively. The rate of pulmonary embolism in 1633 total ankle replacement patients was 0.06%, and there were no recorded DVTs and no deaths. Statistical analysis could only identify risk factors for venous thromboembolic events of increasing age and multiple comorbidities following fracture surgery.

Venous thromboembolism following foot and ankle surgery is extremely rare, but this subset of fracture patients is at a higher risk. However, there is no evidence that thromboprophylaxis reduces this risk, and these national data suggest that prophylaxis is not required in most of these patients.
