The Chopart joint complex is a joint between the midfoot and hindfoot. The static and dynamic support system of the joint is critical for maintaining the medial longitudinal arch of the foot. Any dysfunction leads to progressive collapsing flatfoot deformity (PCFD). Often, the tibialis posterior is the primary cause; however, contrary views have also been expressed. The present investigation intends to explore the comprehensive anatomy of the support system of the Chopart joint complex to gain insight into the cause of PCFD. The study was conducted on 40 adult embalmed cadaveric lower limbs. Chopart joint complexes were dissected, and the structures supporting the joint inferiorly were observed and noted.Aims
Methods
To describe outcome reporting variation and trends in non-pharmacological randomized clinical trials (RCTs) of distal tibia and/or ankle fractures. Five electronic databases and three clinical trial registries were searched (January 2000 to February 2022). Trials including patients with distal tibia and/or ankle fractures without concomitant injuries were included. One reviewer conducted all searches, screened titles and abstracts, assessed eligibility, and completed data extraction; a random 10% subset were independently assessed and extracted by a second reviewer at each stage. All extracted outcomes were mapped to a modified version of the International Classification of Functioning, Disability and Health framework. The quality of outcome reporting (reproducibility) was assessed.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. A questionnaire was sent to all 136 NHS trusts audited in the 2018 National Diabetic Foot Audit (NDFA). The questionnaire asked about the structure of diabetic foot care services.Aims

Surgical options for management of a failed ankle arthroplasty are currently limited; typically conversion to fusion is recommended with only a few patients being considered for revision replacement surgery. This paper presents our experience of revision ankle replacements in a cohort of patients with failed primary replacements. A total of 18 revision TAR in 17 patients were performed in patients with aseptic loosening. The technique was performed by a single surgeon (CSK) over a 4 year period between July 2014 and August 2018 using the Inbone total ankle replacement system. Patient demographics and clinical outcomes were collected retrospectively using - MOXFQ, EQ5D, VAS pain score and patient satisfaction questionnaires.Aim
Method
Venous Thrombo-Embolism is a recognized complication of lower limb immobilization. In the neuropathic patient total contact casting (TCC) is used in the management of acute charcot neuroathropathy and/or to off-load neuropathic ulcers, frequently for long time periods. To our knowledge there is no literature stating the prevalence of VTE in patients undergoing TCC. We perceive that neuropathic patients with active charcot have other risk factors for VTE which would predispose them to this condition and would mandate the use of prophylaxis. We report a retrospective case series assessing the prevalence of VTE in the patients being treated with TCCs. Patients undergoing TCC between 2006 and 2018 were identified using plaster room records. These patients subsequently had clinical letters and radiological reports assessed for details around the TCC episode, past medical history and any VTE events.Background
Methods
Revision options for a failed Total ankle arthroplasty (TAA) have historically been limited to complex hindfoot fusions, bespoke ankle arthroplasty revision or amputation. The patient outcomes of these procedures has been felt to be poor. The introduction of the INBONE-II and INVISION ankle arthroplasty revision systems has created a range of revision arthroplasty options, with the possibility of improved patient outcomes. We aim to report on the early results of 20 sequential revision TAA. All patients undergoing revision TAA with INBONE-II or INVISION had prospective collection of pre-operative and post-operative MOx-FQ and EQ-5D scores. Between September 2013 and June 2019 23 patients underwent revision TAA with mean time from implantation of 35 months (6 to 74). Those with greater than 1 year follow-up had scores included. Other outcomes included radiographic assessment for loosening and revision. 13 patients had INBONE-II and 10 INVISION. None required revision at the time of review. Pre-operative MOx-FQ averaged 40.6 (13.4 pain, 21 walking, 6.2 social). Post-operative MOx-FQ averaged 17.4 (6.2 pain, 8.1 walking, 3.1 social). Average EQ-5D improved from 8 to 6.6 and average EQ-VAS from 60 to 80. On radiograph review one patient had radiolucent lines around their INBONE-II stem evident at 1 year. This had not progressed by 4 years total follow-up. Another patient had uncoupling of part of the stem of her INBONE-II but had not required revision. This was attributed to surgeon error. Revision TAA using the INBONE-II and INVISION systems shows promising early results relating to loosening and revision and good maintained improvement in MOx-FQ and EQ-5D scores. This provides further evidence that patients with a failed TAA can safely have revision rather than having to commit to complex ankle/hindfoot fusion. This provides surgeons with flexibility particularly in those patients with other hindfoot arthritis or arthrodesis.
Total ankle replacement (TAR) is performed for post-traumatic arthritis, inflammatory arthropathy, osteoarthritis and other indications. The Scottish Arthroplasty Project (SAP) began collection of data on TAR in 1997. In this study, using data from the SAP, we look at trends in the use and outcomes of TAR in Scotland. We identified 499 patients from the SAP who underwent TAR between 1997 and 2015 with imaging available on the National Picture Archiving and Communication System (PACS). We identified, and looked at trends in, implant type over the following time periods: 1998–2005; 2006–2010 and 2011–2015. Age, gender, indication and outcomes for each time period were examined and also trends with implant type over time.Introduction
Methods
The importance of total ankle replacement (TAR) implant orientation in the axial plane is poorly understood with major variation in surgical technique of implants on the market. Our aims were to better understand the axial rotational profile of patients undergoing TAR. In 157 standardised CT Scans of end-stage ankle arthritis patients planning to undergo primary TAR surgery, we measured the relationship between the knee posterior condylar axis, the tibial tuberosity, the transmalleolar axis(TMA) and the tibiotalar angle. The foot position was measured in relation to the TMA with the foot plantigrade. The variation between medial gutter line and the line bisecting both gutters was assessed.Background
Methods
The use of a knotless TightRope for the stabilisation of a syndesmotic injury is a well-recognised mode of fixation. It has been described that the device can be inserted using a “closed” technique. This presents a risk of saphenous nerve entrapment and post-operative pain. We aimed to establish the actual risk of injury to the Saphenous Nerve using a “closed” technique for the insertion of a TightRope.Background
Aim
Iatrogenic hallux varus is a rare complication after hallux valgus surgery. Operative treatment comprises a wide variety of techniques, of which the reversed transfer of the abductor hallucis tendon is the most recent described technique. This paper will present the long-term clinical results of the reversed transfer of the abductor hallucis longus. Therefore, we performed a prospective clinical observational study on 16 female patients. Our hypothesis is that the tendon transfer will persist in a good alignment and patient satisfaction on long term. There is a 100% follow-up rate with a range from 10 to 101 months. Patients were subjected to a clinical examination, three questionnaires and their general satisfaction.Background
Methods
Tendinopathy can commonly occur around the foot and ankle resulting in isolated rupture, debilitating pain and degenerative foot deformity. The pathophysiology and key cells involved are not fully understood. This is partly because the dense collagen matrix that surrounds relatively few resident cells limits the ability of previous techniques to identify and target those cells of interest. In this study, we apply novel single cell RNA sequencing (CITE-Seq) techniques to healthy and tendinopathic foot/ankle tendons. For the first time we have identified multiple sub-populations of cells in human tendons. These findings challenge the view that there is a single principal tendon cell type and open new avenues for further study. Healthy tendon samples were obtained from patients undergoing tendon transfer procedures; including tibialis posterior and FHL. Diseased tendon samples were obtained during debridement of intractable Achilles and peroneal tendinopathy, and during fusion of degenerative joints. Single cell RNA sequencing with surface proteomic analysis identified 10 sub-populations of human tendon derived cells. These included groups expressing genes associated with fibro-adipogenic progenitors (FAPs) as well as ITGA7+VCAM1- recently described in mouse muscle but, as yet, not human tendon. In addition we have identified previously unrecognised sub-classes of collagen type 1 associated tendon cells. Each sub-class expresses a different set of extra-cellular matrix genes suggesting they each play a unique role in maintaining the structural integrity of normal tendon. Diseased tendon harboured a greater proportion of macrophages and cytotoxic lymphocytes than healthy tendon. This inflammatory response is potentially driven by resident tendon fibroblasts which show increased expression of pro-inflammatory cytokines. Finally, identification of a previously unknown sub-population of cells found predominantly in tendinopathic tissue offers new insight into the underlying pathophysiology. Further work aims to identify novel proteins targets for possible therapeutic pathways.
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 primary aim of this study was to present the mid-term follow-up of a multicentre randomized controlled trial (RCT) which compared the functional outcome following routine removal (RR) to the outcome following on-demand removal (ODR) of the syndesmotic screw (SS). All patients included in the ‘ROutine vs on DEmand removal Of the syndesmotic screw’ (RODEO) trial received the Olerud-Molander Ankle Score (OMAS), American Orthopaedic Foot and Ankle Hindfoot Score (AOFAS), Foot and Ankle Outcome Score (FAOS), and EuroQol five-dimension questionnaire (EQ-5D). Out of the 152 patients, 109 (71.7%) completed the mid-term follow-up questionnaire and were included in this study (53 treated with RR and 56 with ODR). Median follow-up was 50 months (interquartile range 43.0 to 56.0) since the initial surgical treatment of the acute syndesmotic injury. The primary outcome of this study consisted of the OMAS scores of the two groups.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
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
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
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
To identify a core outcome set of postoperative radiographic measurements to assess technical skill in ankle fracture open reduction internal fixation (ORIF), and to validate these against Van der Vleuten’s criteria for effective assessment. An e-Delphi exercise was undertaken at a major trauma centre (n = 39) to identify relevant parameters. Feasibility was tested by two authors. Reliability and validity was tested using postoperative radiographs of ankle fracture operations performed by trainees enrolled in an educational trial (IRCTN 20431944). To determine construct validity, trainees were divided into novice (performed < ten cases at baseline) and intermediate groups (performed ≥ ten cases at baseline). To assess concurrent validity, the procedure-based assessment (PBA) was considered the gold standard. The inter-rater and intrarater reliability was tested using a randomly selected subset of 25 cases.Aims
Methods
To compare the cost-utility of removable brace compared with cast in the management of adult patients with ankle fracture. 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.Aims
Methods
Treatment for delayed wound healing resulting from peripheral vascular diseases and diabetic foot ulcers remains a challenge. A novel surgical technique named ‘tibial cortex transverse transport’ (TTT) has been developed for treating peripheral ischaemia, with encouraging clinical effects. However, its underlying mechanisms remain unclear. In the present study, we explored the potential biological mechanisms of TTT surgery using various techniques in a rat TTT animal model. A novel rat model of TTT was established with a designed external fixator, and effects on wound healing were investigated. Laser speckle perfusion imaging, vessel perfusion, histology, and immunohistochemistry were used to evaluate the wound healing processes.Aims
Methods
The aim of this study was to investigate whether on-demand removal (ODR) is noninferior to routine removal (RR) of syndesmotic screws regarding functional outcome. Adult patients (aged above 17 years) with traumatic syndesmotic injury, surgically treated within 14 days of trauma using one or two syndesmotic screws, were eligible (n = 490) for inclusion in this randomized controlled noninferiority trial. A total of 197 patients were randomized for either ODR (retaining the syndesmotic screw unless there were complaints warranting removal) or RR (screw removed at eight to 12 weeks after syndesmotic fixation), of whom 152 completed the study. The primary outcome was functional outcome at 12 months after screw placement, measured by the Olerud-Molander Ankle Score (OMAS).Aims
Methods
A multicentre, randomized, clinician-led, pragmatic, parallel-group orthopaedic trial of two surgical procedures was set up to obtain high-quality evidence of effectiveness. However, the trial faced recruitment challenges and struggled to maintain recruitment rates over 30%, although this is not unusual for surgical trials. We conducted a qualitative study with the aim of gathering information about recruitment practices to identify barriers to patient consent and participation to an orthopaedic trial. We collected 11 audio recordings of recruitment appointments and interviews of research team members (principal investigators and research nurses) from five hospitals involved in recruitment to an orthopaedic trial. We analyzed the qualitative data sets thematically with the aim of identifying aspects of informed consent and information provision that was either unclear, disrupted, or hindered trial recruitment.Aims
Methods
Arthroplasty has become increasingly popular to treat end-stage ankle arthritis. Iatrogenic posterior neurovascular and tendinous injury have been described from saw cuts. However, it is hypothesized that posterior ankle structures could be damaged by inserting tibial guide pins too deeply and be a potential cause of residual hindfoot pain. The preparation steps for ankle arthroplasty were performed using the Infinity total ankle system in five right-sided cadaveric ankles. All tibial guide pins were intentionally inserted past the posterior tibial cortex for assessment. All posterior ankles were subsequently dissected, with the primary endpoint being the presence of direct contact between the structure and pin.Aims
Methods
This is a multicentre, non-inventor, prospective observational study of 503 INFINITY fixed bearing total ankle arthroplasties (TAAs). We report our early experience, complications, and radiological and functional outcomes. Patients were recruited from 11 specialist centres between June 2016 and November 2019. Demographic, radiological, and functional outcome data (Ankle Osteoarthritis Scale, Manchester Oxford Questionnaire, and EuroQol five-dimension five-level score) were collected preoperatively, at six months, one year, and two years. The Canadian Orthopaedic Foot and Ankle Society (COFAS) grading system was used to stratify deformity. Early and late complications and reoperations were recorded as adverse events. Radiographs were assessed for lucencies, cysts, and/or subsidence.Aims

The primary objective was to determine the incidence of COVID-19 infection and 30-day mortality in patients undergoing foot and ankle surgery during the global pandemic. Secondary objectives were to determine if there was a change in infection and complication profile with changes introduced in practice. This UK-based multicentre retrospective national audit studied foot and ankle patients who underwent surgery between 13 January and 31 July 2020, examining time periods pre-UK national lockdown, during lockdown (23 March to 11 May 2020), and post-lockdown. All adult patients undergoing foot and ankle surgery in an operating theatre during the study period were included. A total of 43 centres in England, Scotland, Wales, and Northern Ireland participated. Variables recorded included demographic data, surgical data, comorbidity data, COVID-19 and mortality rates, complications, and infection rates.Aims
Methods
The purpose of this study is to examine the adductus impact on the second metatarsal by the nonosteotomy nonarthrodesis syndesmosis procedure for the hallux valgus deformity correction, and how it would affect the mechanical function of the forefoot in walking. For correcting the metatarsus primus varus deformity of hallux valgus feet, the syndesmosis procedure binds first metatarsal to the second metatarsal with intermetatarsal cerclage sutures. We reviewed clinical records of a single surgical practice from its entire 2014 calendar year. In total, 71 patients (121 surgical feet) qualified for the study with a mean follow-up of 20.3 months (SD 6.2). We measured their metatarsus adductus angle with the Sgarlato’s method (SMAA), and the intermetatarsal angle (IMA) and metatarsophalangeal angle (MPA) with Hardy’s mid axial method. We also assessed their American Orthopaedic Foot & Ankle Society (AOFAS) clinical scale score, and photographic and pedobarographic images for clinical function results.Aims
Methods
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. A randomized controlled trial (RCT) of 334 adult patients diagnosed with a closed type C pilon fracture will be conducted. Internal locking plate fixation will be compared with external frame fixation. The primary outcome and endpoint will be the Disability Rating Index (a patient self-reported assessment of physical disability) at 12 months. This will also be measured at baseline, three, six, and 24 months after randomization. Secondary outcomes include the Olerud and Molander Ankle Score (OMAS), the five-level EuroQol five-dimenison score (EQ-5D-5L), complications (including bone healing), resource use, work impact, and patient treatment preference. The acceptability of the treatments and study design to patients and health care professionals will be explored through qualitative methods.Aims
Methods
In the context of tendon degenerative disorders, the need for innovative conservative treatments that can improve the intrinsic healing potential of tendon tissue is progressively increasing. In this study, the role of pulsed electromagnetic fields (PEMFs) in improving the tendon healing process was evaluated in a rat model of collagenase-induced Achilles tendinopathy. A total of 68 Sprague Dawley rats received a single injection of type I collagenase in Achilles tendons to induce the tendinopathy and then were daily exposed to PEMFs (1.5 mT and 75 Hz) for up to 14 days - starting 1, 7, or 15 days after the injection - to identify the best treatment option with respect to the phase of the disease. Then, 7 and 14 days of PEMF exposure were compared to identify the most effective protocol.Aims
Methods
The incidence of acute Achilles tendon rupture appears to be increasing. The aim of this study was to summarize various therapies for acute Achilles tendon rupture and discuss their relative merits. A PubMed search about the management of acute Achilles tendon rupture was performed. The search was open for original manuscripts and review papers limited to publication from January 2006 to July 2017. A total of 489 papers were identified initially and finally 323 articles were suitable for this review.Objectives

Charcot neuroarthropathy is a rare but serious complication of diabetes, causing progressive destruction of the bones and joints of the foot leading to deformity, altered biomechanics and an increased risk of ulceration. Management is complicated by a lack of consensus on diagnostic criteria and an incomplete understanding of the pathogenesis. In this review, we consider recent insights into the development of Charcot neuroarthropathy. It is likely to be dependent on several interrelated factors which may include a genetic pre-disposition in combination with diabetic neuropathy. This leads to decreased neuropeptides (nitric oxide and calcitonin gene-related peptide), which may affect the normal coupling of bone formation and resorption, and increased levels of Receptor activator of nuclear factor kappa-B ligand, potentiating osteoclastogenesis. Repetitive unrecognized trauma due to neuropathy increases levels of pro-inflammatory cytokines (interleukin-1β, interleukin-6, tumour necrosis factor α) which could also contribute to increased bone resorption, in combination with a pre-inflammatory state, with increased autoimmune reactivity and a profile of monocytes primed to transform into osteoclasts - cluster of differentiation 14 (CD14). Increased blood glucose and loss of circulating Receptor for Advanced Glycation End-Products (AGLEPs), leading to increased non-enzymatic glycation of collagen and accumulation of AGLEPs in the tissues of the foot, may also contribute to the pathological process. An understanding of the relative contributions of each of these mechanisms and a final common pathway for the development of Charcot neuroarthropathy are still lacking.
The aim of this retrospective study was to compare the functional
and radiological outcomes of bridge plating, screw fixation, and
a combination of both methods for the treatment of Lisfranc fracture
dislocations. A total of 108 patients were treated for a Lisfranc fracture
dislocation over a period of nine years. Of these, 38 underwent
transarticular screw fixation, 45 dorsal bridge plating, and 25
a combination technique. Injuries were assessed preoperatively according
to the Myerson classification system. The outcome measures included
the American Orthopaedic Foot and Ankle Society (AOFAS) score, the
validated Manchester Oxford Foot Questionnaire (MOXFQ) functional
tool, and the radiological Wilppula classification of anatomical
reduction.Aims
Patients and Methods
The surgical challenge with severe hindfoot injuries is one of technical feasibility, and whether the limb can be salvaged. There is an additional question of whether these injuries should be managed with limb salvage, or whether patients would achieve a greater quality of life with a transtibial amputation. This study aims to measure functional outcomes in military patients sustaining hindfoot fractures, and identify injury features associated with poor function. Follow-up was attempted in all United Kingdom military casualties sustaining hindfoot fractures. All respondents underwent short-form (SF)-12 scoring; those retaining their limb also completed the American Academy of Orthopaedic Surgeons Foot and Ankle (AAOS F&A) outcomes questionnaire. A multivariate regression analysis identified injury features associated with poor functional recovery.Objectives
Methods
Talus fractures have traditionally been reported as having poor outcomes with rates of avascular necrosis in excess of 80% in some studies. It was noted by the senior author that this was not his experience in a tertiary institution with many patients having good to excellent outcomes and lower rates of avascular necrosis than anticipated despite high-energy trauma. The aim of this paper is to review all talus fractures that have been fixed internally at our institution to determine whether current surgical techniques have improved traditionally poor outcomes. This could result in improved outlook for patients on initial presentation and improved ability to manage the long-term consequences of the multiply-injured patient. A review of all lower limb trauma cases from 2012–2015 was made. This yielded 28 talus fractures that had been internally fixed at Southmead hospital. Patients were contacted using telephone and letters. The AAOS Foot and Ankle Outcome Questionnaire, patient satisfaction surveys and analysis of radiographs were made.Introduction
Method
Traditional treatment for end-stage ankle arthritis has been ankle arthrodesis, however ankle arthroplasty is becoming an accepted alternative. The Zenith Ankle (Corin, UK) is 3rd generation implant with a mobile bearing design. In the NJR 2016 report, the Zenith was the commonest ankle prosthesis implanted in the UK. However, compared to other ankle implants, there's little published data on its performance and survival. The aim of this study was to analyse outcome in a consecutive series from a non-designer centre. We conducted a retrospective review of a consecutive series of 118 Zenith Ankle replacements implanted in our Unit (December 2010 to May 2016). Data was collected from our National Joint Registry entries, research databases, patient notes, PACS and PROMS.Introduction
Method
Anatomical reduction and Stable fixation of Lisfranc injuries is considered the gold standard. There is controversy about how it is best achieved. Some surgeons would advocate routine open anatomical reduction, which as a concept was popular in 1980s but the same anatomical reduction and fixation can be achieved percutaneously. We describe our method of close reduction and percutaneous fixation and present our results. 22 patients with a minimum follow up of 12 months were included. We achieved satisfactory anatomical reduction percutaneously in all patients and internal fixation was performed using cannulated screws for medial and middle columns. Functional outcome was evaluated using Foot and Ankle Disability Index (FADI) and components of this score were analysed individually to assess which domain was most affected. Vertical ground reaction forces were measured using a force plate in a walking platform.Aim

The conservative management of stable Weber B fibula fractures remains variable. We thought that the current trend in our institution poses an unnecessary burden on fracture clinics. We reviewed patients referred with Weber B ankle fractures over an 18 month period. Our inclusion criteria were non-diabetic adults, with isolated stable Weber B fractures. Fractures were deemed stable if they had no evidence of talar shift on initial radiographs (< 5mm medial clear space and < 1mm variation between superior and medial clear spaces). Exclusion criteria were unstable fractures on radiographs, or no local follow-up. Management was reviewed from case notes and radiographs. Primary outcome was the stability of the fracture by the end of treatment. Secondary measures were duration of treatment, number of follow up appointments and radiographs, and complications.Introduction
Methods
There is an increasing acceptance that the clinical outcomes following posterior malleolar fractures are less than satisfactory. In our previous multicenter study (Powell, BOFAS 2016) we showed that the Olerud-Molander Ankle Score (OMAS) was 79 for unimalleolar fractures and 65 for bi malleolar fractures, however it dropped significantly to 54 in trimalleolar fractures. In creating a treatment guiding classification, we report our results in a system change in management of posterior malleolar fractures in our unit. All fractures were classified according to Mason and Molloy classification (BOFAS 2015, FAI 2017) based on CT scans obtained pre-operatively. This dictated the treatment algorithm. Type 1 fractures underwent syndesmotic fixation. Type 2A fractures underwent ORIF through a posterolateral incision, and type 2B and 3 fractures underwent ORIF through a posteromedial incision. The patient remained NWB for 6 weeks postoperative. Data was collected from December 2014 to July 2017.Background
Method
Orthopaedic and trauma surgeons not infrequently encounter the hallucal interphalangeal joint sesamoid (HIPJS) in irreducible traumatic dislocations. However, patients with the classic triad of plantar keratoma beneath a hyperextended interphalangeal (IP) joint associated with stiffness of the first metatarsophalangeal joint tend to present to podiatrists rather than orthopaedic surgeons. We present our experience with the HIPJS following first metatarsophalangeal joint (MTP1) arthrodesis in 18 feet of 16 women, aged 42 to 70 years old. Where CT scan was available, volume of the HIPJS was determined using Vitrea Software.Introduction
Methods
Freiberg's Infraction; osteonecrosis of the metatarsal head, is the fourth most common intra-articular osteonecrosis in the body. Surgical intervention is usually reserved for late stage of the disease process (III-V) or failure of conservative management. We evaluated the outcomes of patients treated with primary Interpositional Arthroplasty technique using periosteum and fat for adequate surfacing and as a spacer for Freiberg's Disease. Twenty-three cases (21 patients) were performed from February 2009 – March 2016 (18 women, 5 men). Mean age at surgery was 51.1 years (range 19 – 70.5 years) with 91% affecting the second metatarsal. Twenty-one cases were primary and two cases were revision. Five cases were stage III, 10 were in stage IV and 8 were stage V. All patients underwent Interpositional Arthroplasty using periosteum and fat graft from affected metatarsal inserted as joint spacer and secured with sutures. Patients were followed up by postal questionnaires using two validated questionnaires; MOXFQ and AOFAS. Mean follow-up was 3.7 years (0.6 – 7.6 years). Paired two-tailed student t tests were used to assess clinical significance. The left and right foot was affected in 12 and 11 cases respectively. There were no postoperative infections, non-unions or transfer metatarsalgia. Surgery allowed 8 patients to wear normal footwear, 9 wearing fashion shoes, 5 wearing dress shoes and 5 patients returned to sporting activities. Mean pre-operative and post-operative VAS pain scores were 6.7 (range 4–10) and 3.2 (range 0–0) (p< 0.05). Mean peri-operative AOFAS scores were 43.8 (range 14–14) and 71.3 (range 10–10) (p< 0.05). Mean peri-operative MOXFQ scores were 62.9 (range 23–23) and 31.8 (range 0–0) (p< 0.05). We recommend our novel Interpositional Arthroplasty using periosteum and fat spacer for late stage Freiberg's disease as it can result in significant improvement in pain, prevents donor site morbidity and produces significant functional improvement and patient satisfaction.
This paper tests the null hypothesis that there is no difference in recurrence for mild and moderate hallux valgus treated with Scarf osteotomy in the presence of a disrupted Meary's line compared to an intact line. At a minimum of 3 months follow up we retrospectively analysed radiographs, theatre and clinic notes of 74 consecutive patients treated with Scarf osteotomy for mild and moderate hallux valgus at a single centre. The patients were divided into Group A (n=30) – patients who on pre-operative weight bearing radiographs had a disrupted Meary's line, and Group B (n=44) – those with a normal Meary's line on pre-operative weight bearing radiographs. Our results demonstrate a statistically significant higher recurrence in group A compared to Group B with an odds ratio of 5.2 In group A two out of 30 patients required revision surgery whilst none of the 44 patients in group B needed revision. In Group A the degree of IMA correction achieved equalled 8.1 degrees with a pre and post IMA of 16.0 and 7.9 degrees respectively. For Group B the degree of correction was 8.0 degrees with a pre and post IMA of 14.3 and 6.3 degrees respectively. Eight complications were reported in Group A and 9 in Group B. Our results demonstrate a statistically significant increased risk of recurrence when scarf osteotomy is performed for mild and moderate hallux valgus in the presence of a disrupted Meary's line.
To evaluate the clinical outcome of a new absorbable, gentamycin loaded calcium sulfate/hydroxyapatite biocomposite (CERAMENT™/G) as cavity filler after debridement and removal of infected metalwork in chronic osteomyelitis. We report the retrospective study of prospectively collected data from 36 patients with chronic osteomyelitis from implant infection. Treatment included a single stage protocol with removal of the metalwork, debridement augmented with application of CERAMENT™/G, stabilization, culture-specific antibiotics and primary skin closure or flap. The biocomposite was used for dead space filling after resection of Cierny-Mader (C-M) stage III and IV chronic osteomyelitis. Data were collected on patient age, comorbidities, operation details, microbiology, postoperative complications and type of fixation or plastic surgery. Primary measure of outcome was recurrence rate.Aim

Flexor Hallucis Longus (FHL) tendon transfer is a well-recognised salvage operation for irreparable tendon Achilles (TA) ruptures and intractable Achilles tenonopathy. Several case series describes the technique and results of arthroscopic FHL tendon transfers. We present a comparative case series of open and arthroscopic FHL tendon transfers from Southmead Hospital, Bristol, UK. For the arthroscopic FHL transfers in most cases the patients were positioned semi prone with a tourniquet. A 2 or 3 posterior portal technique was used and the tendon was secured using an RCI screw. The rehabilitation was similar in both groups with 2 weeks in an equinus backslab followed by gradual dorsiflexion in a boot over the following 6 weeks. Anticoagulation with oral aspirin for 6 weeks was used. A retrospective case note review was performed.Introduction
Methods
Isolated Weber B fractures usually heal uneventfully but traditionally require regular review due to the possibility of medial ligament injury allowing displacement. Following recent studies suggesting delayed talar shift is uncommon we introduced a functional treatment protocol and present the early results. 141 consecutive patients presenting acutely with Weber B fractures without talar shift between January and December 2015 were included. Patients were splinted in a removable boot and allowed to weight bear. ED notes and radiographs were reviewed by an Orthopaedic consultant. Patients without signs of medial injury were discharged with an information leaflet and advice. If signs of medial ligament injury were noted or the medial findings were not documented the patient was reviewed in fracture clinic at 4 weeks post-injury. If talar shift developed the patient was to be converted to operative treatment. Olerud and Molander scores were collected between 6 and 12 months post-injury..Introduction
Methods
Injury to the syndesmosis is not always clearly demonstrated on radiographs and different tests have been described to assess for injury. In the presence of a significant injury to the syndesmosis, surgical fixation is often indicated and various fixation methods have been described. If the result of surgery is any mal-reduction of the fibula, this may result in ongoing ankle pain. Assessing how well the fibula has been reduced intra-operatively is currently limited to image intensifier views. We have previously developed a simple assessment, which has been shown to give accurate intra-operative demonstration of an injury to the syndesmosis. Our objective was to ascertain if the same test could demonstrate any malreduction of the fibular after repair of a syndesmosis injury. Seven fresh frozen cadavers had complete sydesmosis disruption performed before fixation using a well-recognised technique with a single 3.5 mm small fragment screw. Purposeful malreduction was performed in three ankles and standard reduction in the remaining four. 2–5mls of contrast medium was then injected into the ankle joint.Introduction

This study analyzes position of the peroneal tendons and status of the superior peroneal retinaculum (SPR) whenever a lateral malleolar bony flake fracture occurs. Twenty-four patients had a lateral malleolar bony fleck on anteroposterior ankle radiographs, either in isolation or associated with other hindfoot injuries. We studied size of the bony flecks, presence or absence of peroneal tendon dislocation and pathoanatomy on CT scans.Background
Methods
MTPJ instability is very common yet there is no consensus of best surgical technique to repair it. The current techniques range from extensive release, K-wire fixation or plantar plate repair, which requires release of remaining intact plantar plate and all collaterals. Such varieties reflect a controversy regarding its aetiology. The aim of this study was to assess how much each structure contributes towards the stability of MTPJ and describing a simple technique designed by the senior author that can anatomically reconstruct all contributing structures to the pathology. Eleven cadaveric toes in two groups (five in group 1 and six in group 2) were included. Dorsal displacement (drawer test) was used to measure instability in an intact MTPJ followed by two different series of sequential sectioning of each part of collateral ligament (PCL and ACL) and part or complete plantar plate. Group 1 result showed that after incising PCL dorsal displacement was 0.51mm, PCL+ACL was 0.8mm and PCL+ACL+50% plantar plate was 2.39mm. Group 2 results showed that after incising 50% plantar plate dorsal displacement was 0.48mm, after full plantar plate 0.62mm, plantar plate +PCL was 0.74mm and plantar plate +PCL+ACL was 1.06mm. To produce significant instability, both collaterals on one side with combination of 50% plantar plate tear was needed. An isolated 50% tear of plantar plate caused less displacement of MTPJ compared to isolated collaterals. PCL contributed more towards the stability of MTPJ when the plantar plate was intact. Whereas, ACL contributed more stability when plantar plate was sectioned. The current practice of releasing the collaterals to gain access for repairing plantar plate by indirect method should be re-evaluated. A new technique of proximal tenotomy of extensor digitorum brevis tendon looped around the transverse ligament and attached to the neck of metatarsal reconstructs both structures (plantar plate and collaterals).
Studies have compared outcomes of first metatarsophalangeal joint (MTPJ1) implant hemiarthroplasty and arthrodesis, but there is a paucity of data on the influence of patient factors on outcomes. We evaluated data from a prospective, RCT of MTPJ1 implant hemiarthroplasty (Cartiva) and arthrodesis to determine the association between patient factors and clinical outcomes. Patients ≥18 years with Coughlin hallux rigidus grade 2, 3, or 4 were treated with implant MTPJ1 hemiarthroplasty or arthrodesis. Pain VAS, Foot and Ankle Ability Measure (FAAM) Sports and ADL, and SF-36 PF scores were obtained preoperatively, and at 2, 6, 12, 24, 52 and 104 weeks postoperatively. Final outcomes, MTPJ1 active peak dorsiflexion, secondary procedures, radiographs and safety parameters were evaluated for 129 implant hemiarthroplasties and 47 arthrodeses. Composite primary endpoint criteria for clinical success included pain reduction ≥30%, maintenance/improvement in function, and no radiographic complications or secondary surgical intervention at 24 months. Predictor variables included: grade; gender; age; BMI; symptom duration; prior MTPJ1 surgery; preoperative hallux valgus angle, ROM, and pain. Two-sided Fisher's Exact test was used (Introduction
Methods
The effect of BMI on patient-reported outcomes following total ankle replacement (TAR) is uncertain and the change in BMI experienced by these patients in the 5 years following surgery has not been studied. We report a series of 106 patients with complete 5-year data on BMI and patient-reported outcome scores. Patients undergoing TAR between 2006 and 2009, took part in the hospital joint registry, which provides routine clinical audit of patient progress following total joint arthroplasty; therefore, ethics committee approval was not required for this study. Data on BMI, Foot and Ankle Score (FAOS) and SF-36 score were collected preoperatively and annually postoperatively. Patients who were obese (BMI >30) had lower FAOS scores pre-operatively and at 5 years, however this did not reach significance. Both obese (p = 0.0004) and non-obese (p < 0.0001) patients demonstrated a significant improvement in FAOS score from baseline to 5 years. This improvement was more marked for the non-obese patients. No significant differences were seen for SF36 scores between obese and non-obese patients either at baseline or 5 years. There was a trend for improved score in both groups. Mean pre-operative BMI was 28.49. Mean post-operative BMI was 28.33. The mean difference between pre- and post-operative BMI was −0.15, which was not statistically significant (p=0.55). There were no significant differences in revisions in the obese (2) and non-obese (1 and one awaited) groups at 5 years. This data supports use of TAR in the obese population, as significant increases in mean FAOS score were seen in this group at 5 years. Obesity did not have a significant influence on patients' overall health perceptions, measured by the SF36 and a trend for improvement was seen in both obese and non-obese patients. TAR cannot be relied upon to result in significant post-operative weight-loss without further interventions.
We describe a novel single incision approach and its safety in the largest reported series of Lisfranc injuries to date. Via separate subcutaneous windows it is possible to access the medial three rays of the foot for bridge plating, without the concern of narrow skin bridges between multiple incisions. A retrospective review identified all 150 patients who underwent a Lisfranc ORIF via the modified dorsal approach at the Royal Melbourne Hospital between January 2011 and June 2016. All patients were operated by a single surgeon. Removal of metalwork (ROM) was routinely undertaken at six months post-operatively via the same incision. Medical recored were reviewed to record patient demographics, mechanism of injury and surgical details. Outpatient notes were reviewed to identify wound-related complications including; delayed wound healing, superficial infection, wound dehiscence, deep infection, complex regional pain syndrome (CRPS), neuroma and impaired sensation. Median follow-up was 1012 days (range 188–2141).Introduction
Methods
MRI is the preferred modality for the diagnosis of ankle joint pathology. Musculoskeletal radiologists aim to determine and report both chondral and/or osseous stability/instability of each lesion. The aim of this study was to specifically analyse the reliability of MRI reported findings in predicting the stability of OCL's in symptomatic patients. A single centre, single surgeon consecutive series of patients who had undergone an ankle arthroscopy procedure preceded by an MRI scan for symptomatic ankle pathology were included in this retrospective clinical study. All MRI scans were reported by a musculoskeletal radiologist. MRI reports and arthroscopic findings were extracted and analysed. Arthroscopy findings were taken as the gold standard.Background

Diabetes is a poor prognostic indicator after an ankle fracture. Many surgeons avoid operating due to concerns regarding complications. We performed a retrospective analysis of complication rates for acute ankle fractures in diabetics with a control non-diabetic patient treated by all surgeons in our unit and assessed factors for success including long-segment fixation. Patient records were cross-referenced with departmental databases and a review of all ankle fractures managed in our department was conducted from 2012. All patients subjected to a retrospective-review of their follow-up for at least 6-months. Radiographs were assessed of the ankle before and at completion of treatment being reviewed independently (RA & FR). We identified the HB1Ac (diabetic-control) and systematic co-morbidities. Fractures were classified into unimalleolar, bi malleolar and trimalleolar and surgery grouped into standard or long-segment-rigid fixation. Statistical analysis was conducted using absolute/relative risk (RR); numbers needed to treat (NNT) were calculated. We compared a control-group, a diabetic group managed conservatively, and undergoing surgery; comparing the concept of rigid fixation and prolonged imobilisation in isolation or combined. Further sub-analysis conducted assessing diabetic neuropathy, retinopathy and nephropathy. Ethics approval was granted as per our institutional policy by our governance lead. We identified 154 diabetic ankle fractures, seventy-six had conservative-treatment; 78 had operative fixation of which 23 had rigid-long-segment-fixation. The diabetic-groups had a higher risk-relative-risk of complication − 3.2 (P< 0.03) being linked to systematic complications of diabetes e.g. neuropathy 5.8 (P< 0.003); HBA1c 4.6 P< 0.004); and neuropathy or retinopathy 6.2 (P< 0.0003). Relative-risk reduction of complications occurred following surgery with prolonged immobilization (0.86) and rigid-fixation (0.65). The Number-Needed-to-Treat required to see a benefit from rigid fixation was 7. Diabetics have a higher risk for complications, however the risk is not as great as previously reported. We provide evidence of rigid-long-segment-fixation with prolonged-immobilization improving-outcomes.
A randomized clinical trial of first metatarsophalangeal (MTP) joint hemiarthroplasty with a synthetic cartilage implant demonstrated equivalent pain, function and safety outcomes to first MTP joint arthrodesis at 2 years. The implant cohort continues to be followed under an extension of the original study and we report on prospectively determined 5+ year outcomes for subjects assessed to date. Patients treated with hemiarthroplasty implant as part of the previously mentioned trial are eligible for enrollment in the extended study (n=135). At the time of this report, 57 patients had reached the 5+ years postoperative time point, of which 5 were lost to follow-up. The remaining 52 patients with mean age of 58.5 (range, 38.0–0.0) underwent physical examination, radiographic evaluation, assessment of implant survivorship and collection of patient completed VAS pain, and Foot and Ankle Ability Measure (FAAM) sports subscale and activities of daily living (ADL) subscale scores. Mean follow-up is 5.8 (range, 4.8–8.4) years.Introduction
Methods
Arthroplasty for treatment of end stage hallux rigidus is controversial. Arthrodesis remains the gold-standard, but this procedure is not without complications, with up to 10% non-union, 14% re-operation and 10% transfer metatarsalgia rates reported. The aim of this study was to analyse the outcome of the double-stemmed silastic implant (Wright-Medical) for end stage hallux rigidus. We conducted a retrospective review of a consecutive series of 108 silastic 1st MTPJ implanted in our Unit (January 2005 – December 2016). Data was collected from our research databases, patient notes, PACS and PROMS. No patient was lost to follow-up.Introduction
Method
The prevalence of symptomatic osteoarthritis (OA) in the knee is 11–11% compared to 3.4–4.4% in the ankle. In addition to this, 70% of ankle arthritis is post-traumatic while the vast majority of knee arthritis is primary OA. Several reports have previously implicated biochemical differences in extracellular matrix composition between these joint cartilages; however, it is unknown whether there is an inherent difference in their transcriptome and how this might affect their respective functionality under load, inflammatory environment etc. Therefore, we have analysed the transcriptome of ankle and knee cartilage chondrocytes to determine whether this could account for the lower prevalence and altered aetiology of ankle OA. Human full-depth articular cartilage was taken from the talar domes (n=5) and the femoral condyles (n=5) following surgical amputation. RNA was extracted and next generation sequencing (NGS) performed using the NextSeq®500 system. Statistical analysis was performed to identify differentially regulated genes (p adj < 0.05). Data was analysed using Integrated Pathway Analysis software and genes of interest validated by quantitative PCR.Introduction
Methods
Total ankle replacement (TAR) is performed for post-traumatic arthritis, inflammatory arthropathy, osteoarthritis and a range of other indications. The Scottish Arthroplasty Project (SAP) began collection of data on TAR in 1997. In this study, using data from the SAP, we examined the annual incidence of TAR between 1997 and 2015. Implant survivorship and the rate of general and joint-specific complications were also analysed. We identified 601 patients from a national arthroplasty database who had undergone total ankle replacement between 1997 and 2015 and followed up these patients to a maximum of 20 years. We used established methods of linkage with national hospital episode statistics, population and mortality data to examine the incidence of complications and implant survivorship.Introduction
Methods
Standard teaching of dislocated ankles was always reduce then x-ray. However the 2016 BOAST guidelines stated “Reduction and splinting should be performed urgently for clinically deformed ankles. Radiographs should be obtained before reduction unless this will cause an unacceptable delay”. We aimed to audit our practice against the BOAST guidelines and look at time from attendance to reduction. We retrospectively reviewed all case notes of patients admitted via A&E at the Northern General Hospital with a fractured ankle between August 2016 and January 2017. Time of arrival, time to x-ray and time to reduction were recorded in a database for analysis.Introduction
Methods
Crossover and claw toe deformity has traditionally been a very difficult condition to manage surgically, with high recurrence rates. Multiple methods have been used to treat this condition. Plantar plate “repair” has recently been advocated, with sutures used to repair an assumed tear. Based on clinical experience and anatomical studies (Deland et al. 1995), we believe the main pathology is a distal migration of the plantar plate complex resulting in exposure of the metatarsal to the thin posterior synovial attachment of the plate. The downward forces on the metatarsal head results in herniation of the head inferiorly. Accordingly we have developed a technique using full cuff release of the plantar plate complex that includes complete release of the collateral ligaments, repositioning the plantar plate anatomically and reinforcing the hernial defect with a synthetic mesh graft. 12 cases of severe crossover toe deformity have undergone plantar plate reconstruction using synthetic mesh graft in addition to other bony procedures (e.g. Weil's osteotomy, PIPJ fusion) since 2015 operated upon by the lead author. We collated data regarding patient satisfaction using Coughlin's Score (Coughlin 1991). We have also evaluated the sustainability of correction and any complications.Introduction
Methods
The purpose of this study was to compare the clinical and radiographic
outcomes of total ankle arthroplasty (TAA) in patients with pre-operatively
moderate and severe arthritic varus ankles to those achieved for
patients with neutral ankles. A total of 105 patients (105 ankles), matched for age, gender,
body mass index, and follow-up duration, were divided into three
groups by pre-operative coronal plane tibiotalar angle; neutral
(<
5°), moderate (5° to 15°) and severe (>
15°) varus deformity.
American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot
score, a visual analogue scale (VAS), and Short Form (SF)-36 score
were used to compare the clinical outcomes after a mean follow-up period
of 51 months (24 to 147).Aims

Inflammation of the retrocalcaneal bursa (RB) is a common clinical problem, particularly in professional athletes. RB inflammation is often treated with corticosteroid injections however a number of reports suggest an increased risk of Achilles tendon (AT) rupture. The aim of this cadaveric study was to describe the anatomical connections of the RB and to investigate whether it is possible for fluid to move from the RB into AT tissue. A total of 20 fresh-frozen AT specimens were used. In ten specimens, ink was injected into the RB. The remaining ten specimens were split into two groups to be injected with radiological contrast medium into the RB either with or without ultrasonography guidance (USG).Objectives
Methods
The aim of this study was to compare the biomechanical stability and clinical outcome of external fixator combined with limited internal fixation (EFLIF) and open reduction and internal fixation (ORIF) in treating Sanders type 2 calcaneal fractures. Two types of fixation systems were selected for finite element analysis and a dual cohort study. Two fixation systems were simulated to fix the fracture in a finite element model. The relative displacement and stress distribution were analysed and compared. A total of 71 consecutive patients with closed Sanders type 2 calcaneal fractures were enrolled and divided into two groups according to the treatment to which they chose: the EFLIF group and the ORIF group. The radiological and clinical outcomes were evaluated and compared.Objectives
Methods
Revision total ankle arthroplasty (TAA) can be extremely challenging due to bone loss and deformity. We present the results examining the preliminary indications and short term outcomes for the use of the Salto XT revision prosthesis. We conducted an IRB approved prospective review revision TAA performed in two institutions using the Salto XT. There were 40 patients (24 females and 16 males with an average age of 65 years (45–83), who had undergone previous TAA (Agility 27, Salto 4, STAR 4, Buechal Pappas 1), and 4 patients who underwent staged procedures for infection. The primary indications for the revision were loosening and subsidence (34), malalignment (17), cyst formation (8), infection (4).Background

Subtalar nonunion has a detrimental effect on patients' function, and pose a significant challenge for surgeons particularly in the setting of higher risk factors. We retrospectively analyzed a consecutive series of 49 subtalar nonunions between October 2001 and July 2013. Patient records and radiographs were reviewed for specific patient demographics and comorbidities, subsequent treatments, revision fusion rate, use of bone graft, complications, and clinical outcome.Background
Methods
Cheilectomy and arthrodesis are accepted procedures for symptomatic hallux rigidus. Although good functional outcomes have been reported, there is little data available on post-operative sporting ability for these patients. We investigated sporting ability and functional outcomes of two cohorts of patients, the first underwent dorsal cheilectomy and the second arthrodesis.Background
Aims
The mid foot joints are usually the first to be affected in Charcot neuroarthropathy (CN). Reconstruction is technically demanding and fraught with complications. We present our experience of mid foot fusion in CN from a tertiary diabetic foot centre. We undertook mid foot corrective fusion in 27 feet (25 patients). Twelve of these had concurrent hind foot fusion. Eleven patients had type 1 diabetes, 12 had type 2 and 2 were non-diabetics. 23 patients were ASA grade 3 and 2 were ASA 2. 21 feet had ulcers preoperatively and mean HbA1c was 8.2. 13 patients had diabetic retinopathy and 6 had nephropathy.Introduction
Patients and methods
Patients with neglected rupture of the Achilles tendon typically present with weakness and reduced function rather than pain. Shortening of the musculotendinous unit and atrophy of the muscle belly in chronic rupture potentially leads to poorer recovery following tendon transfer. Few papers have looked at the outcomes of FHL reconstruction specifically in neglected TA rupture. Of those that have none report functional outcomes following a transtendinous repair. Twenty patients with irreparable unilateral tendoachilles ruptures treated with transtendinous FHL reconstruction between 2003 and 2011 were reviewed. Achilles Tendon Rupture Score (ATRS), AOFAS hindfoot score, Tegner score and SF12 were recorded. Standard isokinetic assessment of ankle plantarflexion was performed with a Cybex dynamometer. Great toe flexion strength was tested clinically.Introduction
Methods
The dichotomy between surgical repair and conservative management of acute Achilles tendon ruptures has been eliminated through appropriate functional management. The orthoses used within functional management however, remains variable. Functional treatment works on the premise that the ankle/hindfoot is positioned in sufficient equinus to allow for early weight-bearing on a ‘shortened’ Achilles tendon. Our aim in this study was to test if 2 common walking orthoses achieved a satisfactory equinus position of the hindfoot. 10 sequentially treated patients with 11 Achilles tendon injuries were assigned either a fixed angle walking boot with wedges (FAWW) or an adjustable external equinus corrected vacuum brace system (EEB). Weight bearing lateral radiographs were obtained in plaster and the orthosis, which were subsequently analysed using a Carestream PACS system. The Mann-Whitney test was used to compare means.Introduction
Methods
To determine the influence of tendo achilles (TA) rupture gap distance and location on clinical outcome managed with accelerated functional rehabilitation. Twenty six patients with acute complete TA ruptures underwent ultrasound (US) within a week of injury. Measurements included the distance of the rupture from the enthesis and the gap distance between the tendon edges in three positions – foot plantigrade, maximum equinus and maximum equinus with 90o knee flexion. All patients were managed non-operatively in functional weightbearing orthoses. Nineteen patients were followed up at a mean of 6.1 years (range 5.8–6.5). Outcomes included ultrasound confirmation of healing, Achilles Tendon Rupture Score (ATRS) and Modified Lepilahti score (MLS).Aim

Injections are used to treat a wide variety of pathologies. Our aim was to evaluate the efficacy and safety of foot and ankle injections in our clinic. We performed a retrospective review of notes and a telephone questionnaire audit into the clinical outcome of all patients who underwent an injection of the foot or ankle in a year. All procedures were performed in an out-patient setting by a consultant musculoskeletal radiologist using either ultrasound or X-ray guidance, with a minimum of two year follow-up. According to the pathology treated, the type of injection included depomedrone, hyaluronic acid and high volume saline injections.Introduction

Müller Weiss disease (MWD) is characterized by lateral navicular necrosis which is associated with a varus alignment of the subtalar joint, varying degrees of arthritis of the talonavicular-cuneiform joints and a paradoxical flatfoot deformity in advanced cases. Although arthrodesis of the hindfoot is commonly used, we present the results of a previously unreported method of treatment using a calcaneus osteotomy incorporating a wedge and lateral translation. Fourteen patients with MWD who were treated with a calcaneus osteotomy were retrospectively reviewed. There were seven females and seven males with an average age of 56 years (range 33–79), and included one grade 5, five grade 4, four grade 3 and four grade 2 patients. Patients had been symptomatic for an average of eleven years (range 1–14), and all underwent initial conservative treatment with an orthotic support that posted the heel into valgus. The primary indication for surgery was a limited but positive response to the use of the orthotic support, and a desire to avoid an arthrodesis of the hindfoot. Patients were followed for an average of three years following the procedure (range 1 – 7 years). Patients rated their pain on a visual analogue pain scale as an average of 8 (range 6–9) prior to surgery and an average of 2 postoperatively (range 0–4). The AOFAS scores improved from a mean of 29 (range 25 – 35) preoperatively to a mean of 79 (range 75–88) postoperatively. Hindfoot range of motion remained and the extent of arthritis of the navicular complex was unchanged. No patient has since required an arthrodesis. Since the majority of MWD patients respond to an orthotic support which changes the load of the hindfoot and forefoot, we believed that patients would respond positively to a calcaneal osteotomy as an alternative treatment.Results
To examine the mid-term survival, clinical and patient reported outcomes of the silastic 1st metatarsophalangeal joint replacement for the treatment of end stage hallux rigidus. We reviewed 83 consecutive silastic arthroplasties performed in 79 patients for end stage hallux rigidus. There were 3 men and 76 women; mean age 63 years (range 45–78 years). No patient was lost to follow up. Average follow-up was 5.3 years (1.1–11.3 years). The EQ 5D–5L Health index, Manchester-Oxford Foot Questionnaire (MOXFQ), visual analogue scale (VAS) of pain and overall satisfaction rate (Likert scale) were collected for patient reported outcomes.Aim
Methods
Patients presenting with an acute tendoachilles (TA) rupture are managed in a dedicated clinic led by a Foot & Ankle Consultant and specialist physiotherapist. The diagnosis is made clinically and no ultrasound scan is performed. All management, rehabilitation and follow-up is undertaken within this clinic by the specialist physiotherapist, with Consultant support as required. Patients are offered a choice of conservative or surgical management (percutaneous TA repair). Both groups undergo a standardised functional rehabilitation regimen. All patients treated through our dedicated clinic between May 2010 and April 2016 were identified. Patient outcomes were reported using the validated Achilles Tendon Repair Score (ATRS). ATRS scores were collected at 3, 6 and 12 months post-injury. Re-rupture and complication rates were also documented.Background
Methods
Treatment for Freiberg's disease is largely conservative. For severe disease and refractory cases, there are various surgical options. Most studies are from the Far-Eastern population and have short follow-up. The purpose of this study was to report the 5 year clinical outcomes of a dorsal closing wedge osteotomy in the treatment of advanced Freiberg´s disease in a Caucasian population. Twelve patients (12 feet), with a mean age of 30.7 years (range 17–55), were treated with a synovectomy and a dorsal closing wedge osteotomy of the affected distal metatarsal. There were 10 females and 2 males. All patients were born in the United Kingdom. Clinical outcomes were independently evaluated pre and postoperatively using the American Orthopaedic Foot and Ankle Society (AOFAS) scoring system and a subjective satisfaction score. Nine (75%) feet involved the 2nd metatarsal and 3 feet (25%) involved the 3rd metatarsal. According to the Smillie classification, 6 feet were Grade IV and 6 feet were grade V. Radiological union was evaluated postoperatively. No patients were lost to follow up and the mean follow-up time was 5.2 years (4–7). AOFAS scores improved from 48.1 +/− 7.4 to 88.9 +/− 10.1 postoperatively (p< 0.001) giving a mean improvement of 40.8. 92% of patients were satisfied with their operation at latest follow-up, reporting excellent or good results. All patients had postoperative radiological union. One patient had a superficial postoperative infection that was successfully treated with oral antibiotics. A dorsal closing wedge osteotomy is an effective treatment of advanced Freiberg´s disease in a Caucasian population, with good outcomes and few complications.
Active patients may benefit from surgical repair of the achilles tendon with the aim of preserving functional length and optimising push-off power. A mini-open device assisted technique has the potential to reduce wound complications, but risks nerve injury. We present the largest published series of midsubstance achilles tendon repairs using the Achillon® device. A prospective cohort study was run at the Princess Royal Devon & Exeter Hospital between 2008 and 2015. We included all patients who presented with a midsubstance Achilles tendon rupture within 2 weeks of injury, and device assisted mini-open repair was offered to a young active adult population. All patients in the conservative and surgical treatment pathway had the same functional rehabilitation protocol with a plaster for 2 weeks, and a VACOped boot in reducing equinus for a further 8 weeks.Introduction
Methods
We performed a longitudinal outcome study involving the operative management of ankle fractures at two university teaching hospitals. This was a retrospective review of the quality of reduction and a prospective study into the functional outcome. All patients undergoing open reduction internal fixation of the ankle between November 2006 and November 2007 at one centre, and January to December 2009 at the other were included. Adequacy of reduction was assessed on the initial post-operative radiographs using Pettrone's criterion. The post-operative functional outcome was recorded using the Lower Extremity Functional Scale (LEFS), completed by postal or telephone follow-up at 64 months post injury (60–74 months).Introduction
Methods
Fixation of posterior malleolar fragments associated with ankle fractures aims to stabilise the syndesmosis and prevent posterior subluxation. Haraguchi described 3 types of posterior malleolar fractures, with type 2 being a medial extension injury, these fractures often involve medial and posterior fragments. We describe the techniques and outcomes for a double window posteromedial approach allowing optimal reduction and stabilisation. A retrospective review was performed at 2 units, Bristol Royal Infirmary and QE Hospitals Birmingham, between August 2014 and April 2016. Inclusion criteria were all patients having this posteromedial approach for closed ankle fracture fixation. Patients were assessed for complications and postoperative ankle function with the Olerud and Molander scoring system.Introduction
Methods
There have been multiple techniques described to determine hindfoot alignment radiographically. The 2-dimensional nature of radiographs fails to take into account the contribution of the remainder of the foot to overall alignment. A new radiographic technique has been published in which the hindfoot alignment is calculated using the Ground Reaction Force Calcanea Offset. This technique accounts for the individual forefoot contribution to alignment, but is still limited by it´s 2-dimensional nature. The purpose of this study was to compare the hindfoot moment arm (HMA) described by Saltzman and the hindfoot alignment angle (HAA) described by Williamson, with a technique determining the ground reaction force calcaneal offset (GRF-CT) using 3-dimensional weight bearing CT Scans. The HMA, HAA, and GRF-CT 3-D weight bearing CT scans were measured by three different investigators. Each of these measurements were calculated twice on separate occasions by each investigator to determine the intra- and inter-observer reliability.Background
Methods
Platelet rich plasma has been advocated for the treatment of plantar fasciitis but there are few good quality clinical trials to support its use. We report a pilot double blind randomised controlled trial of platelet rich plasma versus normal saline. Patients with more than 6 months of MRI proven plantar fasciitis who had failed conservative management were invited to participate in this study. Patients were block randomised to either platelet rich plasma injection (intervention) or equivalent volume of normal saline (control). The techniques used for the injection and rehabilitation were standardised for both groups. The patient and independent assessor were blinded. Visual analogue scale for pain (VAS) and painDETECT were recorded pre-op and at 6 months. Twenty-eight patients (19 females, mean age 50 years) were recruited, with 14 randomised to each arm. At 6 month follow-up, 8 patients (28.6%) were lost to follow-up. There was a significant change in VAS score from baseline to follow-up in both intervention (mean change 37.2, p = 0.008) and control (mean change 42.2, p = 0.003) groups. However there was no difference between the arms in terms of the change in VAS score from baseline to follow-up (p = 0.183). There was no correlation between pre-op PainDETECT score and change in VAS.Methods
Results
We describe a case series using adjuvant calcium sulphate bio composites with antibiotics in treating infected metalwork in the foot and ankle. 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.Aim
Method
This prospective cohort study aimed to determine if the size of the tendon gap following acute tendo Achillis rupture influences the functional outcome following non-operative treatment. All patients presenting with acute unilateral tendo Achillis rupture were considered for the study. Dynamic ultrasound examination was performed to confirm the diagnosis and measure the gap between ruptured tendon ends. Outcome was assessed using dynamometric testing of plantarflexion and the Achilles tendon rupture score (ATRS) six months after the completion of a rehabilitation programme.Aims
Patients and methods
Traditional treatment of idiopathic flatfoot in the adult population include calcaneal neck lengthening or fusions. These surgical methods result in abnormal function with significant complication rates. Our prospective study aimed to quantify the functional and radiological outcome of a new technique for spring ligament reconstruction using a hamstring graft, calcaneal osteotomy and medial head of gastrocnemius recession if appropriate. 22 feet were identified from the senior authors flatfoot reconstructions over a 3 year period (Jan 2013 to Dec 2015). 9 feet underwent a spring ligament reconstruction. The control group were 13 feet treated with standard tibialis posterior reconstruction surgery. Follow up ranged from 8 to 49 months. Functional assessment comprised VAS heath and pain scales, EQ-5D and MOXFQ scores. Radiographic analysis was performed for standardised parameters.Introduction
Methods
We aimed to retrospectively identify risk factors for delayed / non-union for first metatarsophalangeal joint fusion. Case notes and radiograph analysis was performed for operations between April 2014 and April 2016 with at least 3 months post-operative follow up. Union was defined as bridging bone across the fusion site on AP and lateral radiographic views with no movement or pain at the MTPJ on examination. If union was not certain, CT scans were performed. All patients operations were performed/supervised by one of three consultant foot surgeons. Surgery was performed through a dorsal approach using the Anchorage compression plate. Blinded pre-operative AP radiographs were analysed for the presence of a severe hallux valgus angle equal or above 40 degrees. Measurement intra-observer reliability was acceptable (95%CI:1.6–2.3 degrees). Smoking and medical conditions associated with non-union underwent univariate analysis for significance.Introduction
Methods
Metatarsus adductus (MA) increases the risk of recurrence following surgery for hallux valgus (HV). The goal of this study was to analyze patients with severe MA and identify clinical/surgical factors that are associated with a lower rate of recurrent deformity. 587 patients underwent correction of HV deformity. The rate of recurrence of HV was 15% (63 out of 414 patients) in patients without MA (MA angle < 20°) and 29.6% (50 out of 173 patients) in patients with MA. 19 patients with severe MA (>31°) were identified; 8 of 19 had associated tarsometatarsal arthritis, and two patients had a skew foot deformity. Ten patients had severe valgus lesser toe deformities. Clinical information collected included associated diagnoses, the presence of arthritis of the tarsometatarsal joints, the presence and degree of lesser toe valgus deformities and surgical procedures performed. Radiographic recurrence was defined as a postoperative HVA > 20°.Introduction
Methods
Previous studies have individually shown extracorporeal shockwave therapy (ESWT) to be beneficial for mid-substance Achilles tendinopathy, insertional Achilles tendinopathy or plantar fasciitis. The purpose of this pragmatic study was to determine the efficacy of ESWT in managing the three main causes of refractory heel pain in our routine clinical practice. 236 patients (261 feet) aged between 25 – 81 years (mean age 50.4) were treated in our NHS institute with ESWT between April 2014 and May 2016. They all underwent a clinical and radiological assessment (ultrasonography +/− magnetic resonance imaging) to determine the primary cause of heel pain. Patients were subsequently categorized into three groups, mid-substance Achilles tendinopathy (55 cases), insertional Achilles tendinopathy (55 cases) or plantar fasciitis (151 cases). If their symptoms were recalcitrant to compliant first line management for 6 months, they were prescribed three consecutive ESWT sessions at weekly intervals. All outcome measures (foot & ankle pain score, EQ-5D) were recorded at baseline and 3-month follow-up (mean 18.3 weeks, range 11.4 to 41).Background
Methods
Ankle fractures are common injuries presenting to trauma departments and ankle open reduction and internal fixation (ORIF) is one of the first procedures targeted in early orthopaedic training. Failure to address the fracture pattern with the appropriate surgical technique and hardware may lead to early failure resulting in revision procedures or premature degenerative change. Patients undergoing revision ORIF are known to be at much greater risk of complications, and many of these secondary procedures may be preventable. A retrospective analysis of all patients attending our unit for ankle ORIF over a two year period was undertaken. Patients were identified from our Bluespier database and a review of X rays was undertaken. All patients undergoing re-operation within eight weeks of the primary procedure were studied. The cause of primary failure was established and potential contributing patient and surgical factors were recorded.Introduction
Method
Arthroscopic ankle fusion is an effective treatment for end stage ankle arthritis. It reliably improves pain but at the expense of ankle motion. Development of adjacent degenerative joint disease in the foot is thought to be a consequence of ankle fusion due to altered biomechanics. However, it has been reported to be present on pre-operative radiographs in many patients. There is very little evidence reporting the long-term outcomes of patients undergoing arthroscopic ankle fusion and particularly those requiring secondary procedures for adjacent joint disease. We reviewed the operative records of 149 patients who had undergone arthroscopic ankle fusion under the care of two consultant foot and ankle surgeons between 2002 and 2006. We contacted patients by telephone to determine whether they had required further investigation or surgery on the same foot after their index procedure. Secondary outcome measures included a Manchester Oxford Foot Questionnaire (MOQFQ) score and a patient satisfaction score.Introduction

Corrective fusion for the unstable deformed hind foot in Charcot Neuroarthropathy (CN) is quite challenging and is best done in tertiary centres under the supervision of multidisciplinary teams. We present our results with a series of 42 hind foot deformity corrections in 40 patients from a tertiary level teaching hospital in the United Kingdom. The mean patient age was 59 (33–82). 16 patients had type1 diabetes mellitus, 20 had type 2 diabetes and 4 were non-diabetic. 18 patients had chronic ulceration. 17 patients were ASA 2 and 23 were ASA grade 3. All patients had acute single stage correction and Trigen hind foot nail fusion performed through a standard technique by the senior author and managed peri-operatively by the multidisciplinary team. Our outcome measures were limb salvage, deformity correction, ulcer healing, weight bearing in surgical shoes and return to activities of daily living (ADL).Introduction
