Introduction. Scar sensitivity is a recognised complication of foot surgery. However there is very little published about it. This study looks at the incidence and natural history of scar sensitivity following hallux valgus surgery. Materials and Methods. Patients who had open hallux valgus surgery from December 2008 to December 2009, with a minimum follow up of 12 months, were contacted. Data regarding scar symptoms, their duration, severity at their worst and interventions undertaken were collected. Patients also completed a Roles and Maudsley patient satisfaction score. Results. 125 patients were contacted with response rate of 84%. 30% of patients had experienced scar symptoms following surgery. Of these, 20% had undertaken some form of nonsurgical intervention. The mean duration of symptoms was 16 weeks, and 95% of patients experienced resolution of symptoms. 99% of patients would opt to have the surgery again. Roles and Maudsley score ranged from 1 to 2. Discussion. Nearly one third of patients experienced scar symptoms, however nearly all resolved completely with or without simple treatments. Symptoms were not severe and did not affect satisfaction, function or the decision to have the surgery again. Educating patients preoperatively about scar sensitivity can relieve anxiety and improve the patient experience and they can be advised on simple and effective strategies should this common side effect occur. The results of this study provide the surgeon with valuable information in the consent and education of patients. Also, the fact that nearly all symptom settled within 16 weeks brings into question one of the purported advantages of minimally invasive surgery. Conclusion. Scar symptoms following hallux valgus surgery are common, but mild and almost all resolve in time

Background. Lisfranc fracture dislocations are uncommon injuries, which frequently require surgical intervention. Currently, there is varying evidence on the diagnostic utility of plain radiographs (XR) and CT in identifying Lisfranc injuries and concomitant fractures. Our aim was to identify the utility of XR as compared to CT, with the nul hypothesis that there was no difference in fracture identification. Methods. A retrospective assessment of patients who had sustained a Lisfranc injury between 2013 and 2022 across two trauma centres within the United Kingdom who underwent surgery. Pre-operative XR and CT images were reviewed independently by 2 reviewers to identify the presence of associated fractures. Results. A total of 175 patients were included. Our assessment identified that XR images significantly under-diagnosed all metatarsal and midfoot fractures. The largest discrepancies between XR and CT in their rates of detection were in fractures of the cuboid (5.7% vs 28%, p<0.001), medial cuneiform (20% vs 51%, p=0.008), lateral cuneiform (4% vs 36%, p=0.113), second metatarsal (57% vs 82%, p<0.001), third metatarsal (37% vs 61%, p<0.001) and fourth metatarsal (26% vs 43%, p<0.001). As compared to CT, the sensitivity of XR was low. The lowest sensitivity for identification however was lateral foot injuries, specifically fractures of the lateral cuneiform (sensitivity 7.94%, specificity 97.3%), cuboid (sensitivity 18.37%, specificity 99.21%), fourth (sensitivity 46.7%, specificity 89.80%) and fifth metatarsal (sensitivity 45.00%, specificity 96.10%). Conclusion. From our analysis, we can determine that XR significantly under-diagnoses associated injuries in patient sustaining an unstable Lisfranc injury, with lateral foot injuries being the worst identified. We advised the use of CT imaging in all cases for appropriate surgical planning

Aims. To compare the cost-utility of removable brace compared with cast in the management of adult patients with ankle fracture. Methods. A within-trial economic evaluation conducted from the UK NHS and personnel social services (PSS) perspective. Health resources and quality-of-life data were collected as part of the Ankle Injury Rehabilitation (AIR) multicentre, randomized controlled trial over a 12-month period using trial case report forms and patient-completed questionnaires. Cost-utility analysis was estimated in terms of the incremental cost per quality adjusted life year (QALY) gained. Estimate uncertainty was explored by bootstrapping, visualized on the incremental cost-effectiveness ratio plane. Net monetary benefit and probability of cost-effectiveness were evaluated at a range of willingness-to-pay thresholds and visualized graphically. Results. The incremental cost and QALYs of using brace over a 12-month period were £46.73 (95% confidence interval (CI) £-9 to £147) and 0.0141 (95% CI -0.005 to 0.033), respectively. The cost per QALY gained was £3,318. The probability of brace being cost-effective at a £30,000 per QALY willingness-to-pay threshold was 88%. The results remained robust to a range of sensitivity analyses. Conclusion. This within-trial economic evaluation found that it is probable that using a removable brace provides good value to the NHS when compared to cast, in the management of adults with ankle fracture.

Background. Masses are not uncommon in the foot and ankle. Most of these masses are benign, often leading clinicians to underestimate their potential for malignancy. Methods. We conducted a retrospective review of our clinical records, on patients with histologically confirmed musculoskeletal tumours of the foot and ankle, treated in a single nstitution between 2010 and 2019. The maximum diameter of each lesion was determined through MRI or Ultrasound analysis in centimeters. To develop a scoring system we compared the risk of malignancy with five criteria: site (proximal or distal to the first TMTJ), gender, age, composition and the diameter as observed. Results. Our study included 496 patients, of whom 39 (7.9%) were identified as having malignancies. The incidence of malignancy demonstrated an increased propensity among male patients, patients over 50 years of age and lesions located proximal to the TMTJ. A ROC Analysis determined that lesions measuring over 2.85 cm had an increased risk of malignancy, with a PPV of 31.1%, a NPV of 94.2%, a Sensitivity of 0.82, and a Specificity of 0.62. These identified patterns of risk were employed to formulate a scoring system, aimed at facilitating informed clinical judgment in the referral of patients to regional tumor services. Conclusion. The new OxFAT scoring system highlights the importance of lesion size, site, age and gender of the patient in determining the risk of malignancy in lump in the foot and ankle. We propose this new scoring system to aid health care professionals in managing these patients. Based on our results any patient with a foot or ankle mass of less than 2.85cm, an OxFAT score < 4/7 and no malignant or sinister features on MRI or USS can be managed locally with excision biopsy. All other patients should be referred urgently to a Regional Tumour Service

Lisfranc injuries were previously described as fracture-dislocations of the tarsometatarsal joints. With advancements in modern imaging, subtle Lisfranc injuries are now more frequently recognized, revealing that their true incidence is much higher than previously thought. Injury patterns can vary widely in severity and anatomy. Early diagnosis and treatment are essential to achieve good outcomes. The original classification systems were anatomy-based, and limited as tools for guiding treatment. The current review, using the best available evidence, instead introduces a stability-based classification system, with weightbearing radiographs and CT serving as key diagnostic tools. Stable injuries generally have good outcomes with nonoperative management, most reliably treated with immobilization and non-weightbearing for six weeks. Displaced or comminuted injuries require surgical intervention, with open reduction and internal fixation (ORIF) being the most common approach, with a consensus towards bridge plating. While ORIF generally achieves satisfactory results, its effectiveness can vary, particularly in high-energy injuries. Primary arthrodesis remains niche for the treatment of acute injuries, but may offer benefits such as lower rates of post-traumatic arthritis and hardware removal. Novel fixation techniques, including suture button fixation, aim to provide flexible stabilization, which theoretically could improve midfoot biomechanics and reduce complications. Early findings suggest promising functional outcomes, but further studies are required to validate this method compared with established techniques. Future research should focus on refining stability-based classification systems, validation of weightbearing CT, improving rehabilitation protocols, and optimizing surgical techniques for various injury patterns to ultimately enhance patient outcomes.

Aims

The aim of this study was to compare the longer-term outcomes of operatively and nonoperatively managed patients treated with a removable brace (fixed-angle removable orthosis) or a plaster cast immobilization for an acute ankle fracture.

Aims

The optimal management of posterior malleolar ankle fractures, a prevalent type of ankle trauma, is essential for improved prognosis. However, there remains a debate over the most effective surgical approach, particularly between screw and plate fixation methods. This study aims to investigate the differences in outcomes associated with these fixation techniques.

Aims

The Vantage Total Ankle System is a fourth-generation low-profile fixed-bearing implant that has been available since 2016. We aimed to describe our early experience with this implant.

Aims

Calcaneal osteomyelitis remains a difficult condition to treat with high rates of recurrence and below-knee amputation, particularly in the presence of severe soft-tissue destruction. This study assesses the outcomes of single-stage orthoplastic surgical treatment of calcaneal osteomyelitis with large soft-tissue defects.

Aims

This study aimed to compare the outcomes of two different postoperative management approaches following surgical fixation of ankle fractures: traditional cast immobilization versus the Early Motion and Directed Exercise (EMADE) programme.

Introduction:. Instability and synovitis of the lesser metatarsalphalangeal (MTP) joints is a significant cause of forefoot pain. Plantar plate imaging traditionally has been through MRI and fluoroscopic arthrography. We have described ultrasound arthrography as a less resource-intensive technique without radiation exposure. We report the correlation between ultrasound arthographic and surgical findings. Methods:. Patients with lesser MTP joint instability and pain underwent ultrasound arthrography by a consultant musculoskeletal radiologist. The main finding was the presence of a full or partial tear of the plantar plate. In some patients the location of the tear along with its size in the long and short axis was also reported. Authors who were not involved in the imaging or surgery reviewed the operation notes of patients who underwent surgery to identify. Whether a partial or full thickness tear was identified. Size and location of the tear. The accuracy of ultrasound arthrography was calculated using surgical findings as the standard. Results:. 53 patients with 55 joints underwent ultrasound arthrography, and of these 34 went on to have surgery. 23 patients had adequate documentation of surgical and ultrasound findings. Surgery confirmed plantar plate tears in 21 patients (91.3%) with 9 full thickness tears and 7 partial thickness tears confirmed both operatively and with ultrasound (in 5 patients the operation note did not specify completeness of tear). In 2 patients, in whom ultrasound demonstrated a partial thickness tear, no tear was found at surgery. The sensitivity of ultrasound arthrography for plantar plate tears is 100%, specificity is 0% (although based on few patients), and positive predictive value of 91.3%. Conclusion:. Ultrasound arthrography has a high sensitivity, but low specificity for plantar plate tears, comparable with ultrasound in previous studies. It allows differentiation of partial and full thickness tears which may be important for treatment

Aims

In our unit, we adopt a two-stage surgical reconstruction approach using internal fixation for the management of infected Charcot foot deformity. We evaluate our experience with this functional limb salvage method.

Aims

A pilon fracture is a severe ankle joint injury caused by high-energy trauma, typically affecting men of working age. Although relatively uncommon (5% to 7% of all tibial fractures), this injury causes among the worst functional and health outcomes of any skeletal injury, with a high risk of serious complications and long-term disability, and with devastating consequences on patients’ quality of life and financial prospects. Robust evidence to guide treatment is currently lacking. This study aims to evaluate the clinical and cost-effectiveness of two surgical interventions that are most commonly used to treat pilon fractures.

Aim. We describe a case series using adjuvant calcium sulphate bio composites with antibiotics in treating infected metalwork in the foot and ankle. Method. 11 patients aged 22–81 (9 males, 2 females) were treated with clinical evidence of infected limb metal work from previous orthopaedic surgery. Metal work removal with intra osseous application of either cerement in 8 cases (10–20ml including 175mg–350mg gentamycin) or stimulan in 3 cases (5–12ml including 1g vancomycin) into the site was performed. Supplemental systemic antibiotic therapy (oral/intravenous) was instituted based on intraoperative tissue culture and sensitivity. Results. 7 patients had infected ankle metalwork, 2 had infected foot metalwork and 2 had infected external fixators. Metal work was removed in all cases. Mean pre operative CRP was 25.4 mg/l (range 1–137mg/l). Mean postoperative CRP at 1 week was 15.4mg/l (range 2–36mg/l) and at 1 month was 16.1mg/l (range 2–63mg/l). Mean pre op WCC was 8.5×10. 9. (range 6.2–10.6×10. 9. ). Mean post op WCC at 1 week was 8.8×10. 9. (range 5.1–12.7×10. 9. ) and 1 month was 7.1×10. 9. (range 3.7–10.4×10. 9. ). Organisms cultured included enterobacter, staphylococcus species, stenotrophomonas, acinetobacter, group B streptococcus, enterococcus, escherichia coli, pseudomonas, morganella morganii and finegoldia magna. Infection eradication as a single stage procedure with primary would closure and healing was achieved in 10 out of 11 cases (90.9%). No additional procedures were required in these cases. Conclusions. Our results support the use of a calcium sulphate bio composite with antibiotic as an adjuvant for effective local infection control in cases with implant related bone sepsis. The technique is well tolerated with no systemic or local side effects. Our results show that a single stage implant removal, debridement and local antibiotic delivery can achieve over 90% success rates. We theorise that it could minimise the need for prolonged systemic antibiotic therapy in such cases

Introduction:. Failure to adequately treat an injury of the syndesmosis leads to poor functional outcomes and posttraumatic arthritis. Many techniques have been proposed to salvage chronic instability. We report on the largest series of chronic syndesmotic injuries to be managed by syndesmotic arthrodesis from Europe to date. Aim:. To determine the radiographic and clinical outcomes for this technique at our institute. Methods:. Patients were followed-up prospectively. Relevant radiological and clinical data were obtained from electronic and case note review. The AOFAS score was utilised. Results:. A total of 6 patients were found. The average age was 33 years and the mean length of follow-up was 20 months. Arthrodesis was radiologically successful in all cases. Mean pre-operative and post-operative AOFAS scores were 70 and 82 respectively. All patients had some persistent ankle pain. One third had radiological progression of ankle osteoarthritis. Complications consisted of one patient with scar sensitivity. Conclusions:. This technique has a role in the salvage of chronic ankle syndesmotic instability. However patients must be counselled to the likelihood of ongoing symptoms

We undertook a retrospective review of 24 arthroscopic procedures in patients with symptomatic ossicles around the malleoli of the ankle. Most of the patients had a history of injury and localised tenderness in the area coinciding with the radiological findings. Contrast-enhanced three-dimensional fast-spoiled gradient-echo MRI was performed and the results compared with the arthroscopic findings. An enhanced signal surrounding soft tissue corresponding to synovial inflammation and impingement was found in 20 patients (83%). The arthroscopic findings correlated well with those of our MRI technique and the sensitivity was estimated to be 91%. At a mean follow-up of 30.5 months (20 to 86) the mean American Orthopaedic Foot and Ankle Society score improved from 74.5 to 93 points (p < 0.001). Overall, the rate of patient satisfaction was 88%. Our results indicate that symptomatic ossicles of the malleoli respond well to arthroscopic treatment

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

Background. Cartilage lesions in chronic lateral ligament deficiency are common with the incidence rates mentioned in the previous literature up to 30%. However, other intra-articular pathologies in the unstable ankle have received little attention. Anterolateral impingement associated with synovitis and scarring is a less recognised feature in the treatment of chronic instability. The aim of our study was to ascertain the incidence of chondral and anterolateral impingement lesions in the symptomatic lateral ligament complex deficiency. Methods. We performed a retrospective study of all consecutive patients who underwent modified Brostrom repair for symptomatic recurrent instability of the ankle. All patients underwent a MRI scan prior to surgery. Arthroscopy was performed in all the patients before lateral ligament reconstruction. Seventy seven patients with 78 ankles were included in the study. Patients who had previous ankle surgery or inflammatory arthropathy were excluded. Data was obtained from clinical and radiological records. Arthroscopic findings were recorded in detail during the surgery. Results. The mean age was 29.8 years (Range 18.2 – 58 yrs). There were 44 females and 34 males in the study. The incidence of chondral lesions were 11.5% (9 out of 78 ankles). The commonest site for chondral defect was the anteromedial talar dome. The incidence of anterolateral impingement which required arthroscopic debridement was 48.7% (38 ankles). A further 10 ankles revealed non-specific synovitis and scarring which was debrided. The sensitivity and specificity of the MRI scans in the assessment of chondral lesions is 91% and 100%. Conclusion. The incidence of chondral lesions in chronic ankle instability is lower than previously published literature. However, soft tissue impingement lesions have a much higher incidence and require debridement. Arthroscopic examination and debridement of impingement prior to lateral ligament reconstruction of the ankle is quintessential in the management of chronic anterolateral instability

Aims

Tibiotalocalcaneal (TTC) fusion is used to treat a variety of conditions affecting the ankle and subtalar joint, including osteoarthritis (OA), Charcot arthropathy, avascular necrosis (AVN) of the talus, failed total ankle arthroplasty, and severe deformity. The prevalence of postoperative complications remains high due to the complexity of hindfoot disease seen in these patients. The aim of this study was to analyze the relationship between preoperative conditions and postoperative complications in order to predict the outcome following primary TTC fusion.

Aims

The aim of this study was to describe the technique of distraction osteogenesis followed by arthrodesis using internal fixation to manage complex conditions of the ankle, and to present the results of this technique.
