Anatomic reduction of talar body fractures is critical in restoring congruency to the talocrural joint. Previous studies have indicated a maximum of 25% talar body exposure without malleolar osteotomy. The aim of this study was to investigate the percentage talar body exposure when using the lateral transligamentous approach. The lateral transligamentous approach to the talus was undertaken in 10 fresh frozen cadaveric specimens by surgeons inexperienced in the approach, following demonstration of the technique. An incision was made on the anterolateral aspect of the ankle augmented by the removal of the anterior talofibular ligament (ATFL) and the calcaneofibular ligament (CFL) from their fibular insertions. A bone lever was then placed behind the lateral aspect of the talus and levered forward with the foot in equinus and inversion. The talus was disarticulated and high resolution images were taken of the talar dome surface. The images were overlain with a reproducible nine-grid division. Accessibility to each zone within the grid with a perpendicular surgical blade was documented. ImageJ software was used to calculate the surface area exposed with each approach.Introduction
Methods
There are many different procedures described for the correction of hallux valgus deformity. Minimally invasive surgery has become increasingly popular, with clinical and radiological outcomes comparable to traditional open osteotomy approaches. There is increasing interest in hallux valgus deformity correction using third-generation minimally invasive chevron akin osteotomy (MICA) technique. To assess the radiographic correction and 2 year clinical outcomes of third-generation MICA using validated outcome measures.Background
Objective
Charcot neuroarthropathy (CN) of foot and ankle presents significant challenges to the orthopaedic foot and ankle surgeon. Current treatment focuses on conservative management during the acute CN phase with offloading followed by deformity correction during the chronic phase. However, the deformity can progress in some feet despite optimal offloading resulting ulceration, infection, and limb loss. Our aim was to assess outcomes of primary surgical management with early reconstruction. Between December 2011 and December 2019, 25 patients underwent operative intervention at our specialist diabetic foot unit for CN with progressive deformity and or instability despite advanced offloading. All had peripheral neuropathy, and the majority due to diabetes. Twenty-six feet were operated on in total - 14 during Eichenholtz stage 1 and 12 during stage 2. Fourteen of these were performed as single stage procedures, whereas 12 as two-stage reconstructions. These included isolated hindfoot reconstructions in seven, midfoot in four and combined in 14 feet. Mean age at the time of operation was 54. Preoperative ulceration was evident in 14 patients.Introduction
Methods
Surgical intervention for hallux valgus and hallux rigidus is an option for patients presenting with severe pain and deformity. Literature suggest that patients with high Pain Catastrophisation Scores (PCS) have poorer outcomes in spinal and to a lesser extent in arthroplasty surgery. There is however very little evidence pertaining to foot and ankle surgery. We aimed to study whether catastrophisation as measured by PCS influenced the outcomes following surgery for Hallux valgus and rigidus.Background
Aim
RHF nail is an important tool for simultaneous ankle and subtalar joint stabilisation +/− fusion. Straight and curved RHF nails are available to use, but both seem to endanger plantar structures, especially the lateral plantar artery and nerve and Baxter's nerve. There is a paucity of literature on the structures at risk with a straight RHF nail inserted along a line bisecting the heel pad and the second toe (after Stephenson et al). In this study, plantar structures ‘at risk’ were studied in relation to a straight nail inserted as above. Re-creating real-life conditions and strictly following the recommended surgical technique with regards to the incision and guide-wire placement, we inserted an Orthosolutions Oxbridge nail into the tibia across the ankle and subtalar joints in 6 cadaveric specimens. Tissue flaps were then raised to expose the heel plantar structures and studied their relation to the inserted nail.Background
Methods
Recent large studies of third-generation minimally invasive hallux valgus surgery (MIS) have demonstrated significant improvement in clinical and radiological outcomes. It remains unknown whether these clinical and radiological outcomes are maintained in the medium to long-term. The aim of this study was to investigate the five-year clinical and radiological outcomes following third-generation MIS hallux valgus surgery. A retrospective observational single surgeon case series of consecutive patients undergoing primary isolated third-generation percutaneous Chevron and Akin osteotomies (PECA) for hallux valgus with a minimum 60 month clinical and radiographic follow up. Primary outcome was radiographic assessment of the hallux valgus angle (HVA) and intermetatarsal angle (IMA) pre-operatively, 6 months and ≥60 months following PECA. Secondary outcomes included the Manchester-Oxford Foot Questionnaire, patient satisfaction, Euroqol-5D Visual Analogue Scale and Visual Analogue Scale for Pain.Background
Methods
Procedural sedation (PS) requires two suitably qualified clinicians and a dedicated monitored bed space. We present the results of intra-articular haematoma blocks (IAHB), using local anaesthetic, for the manipulation of closed ankle fracture dislocations and compared resource use with PS. Patients received intra-articular ankle haematoma blocks for displaced ankle fractures requiring manipulation between October 2020 to April 2021. The technique used 10ml of 1% lignocaine injected anteromedially into the tibiotalar joint. Pain scores (VAS), time from first x-ray to reduction, and acceptability of reduction were recorded. A comparison was made by retrospective analysis of patients who had undergone PS for manipulation of an ankle fracture over the six month period March – August 2020.Background
Methods
Open or arthroscopic ankle fusion (AAF) is a successful operative treatment for end-stage ankle arthritis. Evidence suggest that AAFs have better outcomes. In addition to the operative technique other patient-factors can influence outcomes. The most significant complication of ankle fusion is a non-union. To better understand the risk factors related to this we undertook a retrospective investigation of primary AAFs. We reviewed all AAFs conducted at our institution over a 10-year period. Patients excluded if they had simultaneous fusion of neighbouring joints or were lost to follow-up. The primary outcome variable was radiographic union. Other operative complications were analysed as secondary outcomes. Two hundred and eighty-four eligible AAFs in 271 patients were performed over the study period.Background
Methods
Recurrence after surgical correction of hallux valgus may be related to coronal rotation of the first metatarsal. The scarf osteotomy is a commonly used procedure for correcting hallux valgus but has limited ability to correct rotation. Using weightbearing computed tomography (WBCT), we aimed to measure the coronal rotation of the first metatarsal before and after a scarf osteotomy, and correlate these to clinical outcome scores. We retrospectively analyzed 16 feet (15 patients) who had a WBCT before and after scarf osteotomy for hallux valgus correction. On both scans, hallux valgus angle (HVA), intermetatarsal angle, and anteroposterior/lateral talus-first metatarsal angle were measured using digitally reconstructed radiographs. Metatarsal pronation (MPA), alpha angle, sesamoid rotation angle and sesamoid position was measured on standardized coronal CT slices. Preoperative and postoperative(12 months) clinical outcome scores(MOxFQ and VAS) were captured.Introduction
Methods
Hindfoot intramedullary nail fixation (HFN) or fibula pro-tibial screw fixation (PTS) are surgical options for ankle fractures in patients with multiple co-morbidities; we compared their outcomes. A retrospective review of 135 patients who underwent HFN fixation (87 patients) or PTS fixation (48 patients) for ankle fractures (AO/OTA A/B/C) from 5 major trauma centres. Patient demographic data, co-morbidities, Charlson Co-morbidity Index Score (CCIS), weight-bearing, and post-operative complications were recorded. Radiographs were assessed for non-union and anatomical reduction.Introduction
Methods
Charcot neuroarthropathy is a debilitating condition that frequently leads to skeletal instability, and has an increased risk of ulceration leading to infection and amputation. However, surgical reconstruction may offer limb salvage and restauration of an ulcer-free, plantigrade stable foot for functional weight-bearing. We report on our case series according to a prospective protocol and analyse factors leading to a favourable outcome. We report a prospective follow-up of 62 patients undergoing Charcot reconstruction, May 2014- Jan 2022, by two surgeons. Peripheral vascular disease was routinely assessed using Duplex scan and major arterial disease was treated before reconstruction. Utilising 3D modelling, pre-operative planning and standardised osteotomies, we performed anatomical correction with radiological evidence. Definitive fixation was undertaken with internal fixation to stabilise the hindfoot. Multivariant analysis was performed to assess risk factors for failure (P>0.05 statistical significance).Introduction
Methods
Neglected clubfoot in this series is defined as untreated equino-cavo-adducto-varus in older children, or adults. Relapsed clubfoot is the residual deformity that remains after single or multiple surgical interventions. Severe neglected clubfoot rarely exists today in developed countries, except in some emigrants from low- and middle-income countries. Acute surgical management with corrective mid-foot osteotomy and elongation of the Achilles tendon has excellent functional outcome. To assess the functional outcome of acute correction of neglected Talipes-quino-varus deformity in adults.Background
Objective
Ankle and hindfoot fusion in the presence of large bony defects represents a challenging problem. Treatment options include acute shortening and fusion or void filling with metal cages or structural allograft, which both have historically low union rates. Impaction grafting is an alternative option. A 2 centre retrospective review of consecutive series of 32 patients undergoing hindfoot fusions with impaction bone grafting of morselised femoral head allograft to fill large bony void defects was performed. Union was assessed clinically and with either plain radiography or weightbearing CT scanning. Indications included failed total ankle replacement (24 patients), talar osteonecrosis (6 patients) and fracture non-union (2 patients). Mean depth of the defect was 29 ±10.7 mm and mean maximal cross-sectional area was 15.9 ±5.8 cm2. Tibiotalocalcaneal (TTC) arthrodesis was performed in 24 patients, ankle arthrodesis in 7 patients and triple arthrodesis in 1 patient.Background
Methods
Studies have compared open reduction internal fixation (ORIF) with fibular nail fixation (FNF) and shown reduced wound complications with minimal difference to PROMS in the short term. Our aim is to compare long-term outcomes for unstable ankle fractures at 10 year follow up. Patients from a previously conducted RCT were contacted at a minimum of 10 years post intervention at a single study centre. Case notes were reviewed, and patient reported outcome measures acquired at 10 years.Background
Methods
Masses are not uncommon in the foot and ankle. Most of these masses are benign, often leading clinicians to underestimate their potential for malignancy. 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.Background
Methods
The rationale for exacting restoration of skeletal anatomy after unstable ankle fracture is to improve outcomes by reducing complications from malunion; however, current definitions of malunion lack confirmatory clinical evidence. Radiological (absolute radiological measurements aided by computer software) and clinical (clinical interpretation of radiographs) definitions of malunion were compared within the Ankle Injury Management (AIM) trial cohort, including people aged ≥ 60 years with an unstable ankle fracture. Linear regressions were used to explore the relationship between radiological malunion (RM) at six months and changes in function at three years. Function was assessed with the Olerud-Molander Ankle Score (OMAS), with a minimal clinically important difference set as six points, as per the AIM trial. Piecewise linear models were used to investigate new radiological thresholds which better explain symptom impact on ankle function.Aims
Methods
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. We conducted a comprehensive review of clinical trials comparing anteroposterior (A-P) screws, posteroanterior (P-A) screws, and plate fixation. Two investigators validated the data sourced from multiple databases (MEDLINE, EMBASE, and Web of Science). Following PRISMA guidelines, we carried out a network meta-analysis (NMA) using visual analogue scale and American Orthopaedic Foot and Ankle Score (AOFAS) as primary outcomes. Secondary outcomes included range of motion limitations, radiological outcomes, and complication rates.Aims
Methods
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. This is a secondary analysis of a multicentre randomized controlled trial comparing adults with an acute ankle fracture, initially managed either by operative or nonoperative care. Patients were randomly allocated to receive either a cast immobilization or a fixed-angle removable orthosis (removable brace). Data were collected on baseline characteristics, ankle function, quality of life, and complications. The Olerud-Molander Ankle Score (OMAS) was the primary outcome which was used to measure the participant’s ankle function. The primary endpoint was at 16 weeks, with longer-term follow-up at 24 weeks and two years.Aims
Methods
Despite the increasing numbers of ankle arthroplasties, there are limited studies on their survival and comparisons between different implants. The primary aim of this study was to determine the failure rates of primary ankle arthroplasties commonly used in the UK. A data linkage study combined National Joint Registry (NJR) data and NHS Digital data. The primary outcome of failure was defined as the removal or exchange of any components of the implanted device. Life tables and Kaplan-Meier survival charts were used to illustrate survivorship. Cox proportional hazards regression models were fitted to compare failure rates between 1 April 2010 and 31 December 2018.Aims
Methods
To systematically review qualitative studies of patients with distal tibia or ankle fracture, and explore their experience of injury and recovery. We undertook a systematic review of qualitative studies. Five databases were searched from inception to 1 February 2022. All titles and abstracts were screened, and a subset were independently assessed. Methodological quality was appraised using the Critical Appraisal Skills Programme (CASP) checklist. The GRADE-CERQual checklist was used to assign confidence ratings. Thematic synthesis was used to analyze data with the identification of codes which were drawn together to form subthemes and then themes.Aims
