We describe a retrospective review of the clinical and radiological parameters of 32 feet in 30 patients (10 men and 20 women) who underwent correction for malalignment of the hindfoot with a modified double arthrodesis through a medial approach. The mean follow-up was 21 months (13 to 37). Fusion was achieved in all feet at a mean of 13 weeks (6 to 30). Apart from the calcaneal pitch angle, all angular measurements improved significantly after surgery. Primary wound healing occurred without complications. The isolated medial approach to the subtalar and talonavicular joints allows good visualisation which facilitated the reduction and positioning of the joints. It was also associated with fewer problems with wound healing than the standard lateral approach.
Introduction. Severe, multiplanar, fixed, pantalar deformities present a challenge to orthopaedic surgeons. Surgical options include limb salvage or amputation. This study compares outcomes of patients with such deformities undergoing limb preservation with either pantalar fusion (PTF) or talectomy and tibiocalcaneal fusion (TCF), versus below knee amputation (BKA). Methods. Fifty-one patients undergoing either PTF, TCF and BKA for failed management of
Background. The complex deformities in cavovarus feet may be difficult to assess and understand. Weight-bearing CT (WBCT) is increasingly used to evaluate complex deformities. However, the bone axes may be difficult to calculate in the setting of
We reviewed 91 patients (103 feet) who underwent
a Ludloff osteotomy combined with additional procedures. According
to the combined procedures performed, patients were divided into
Group I (31 feet; first web space release), Group II (35 feet; Akin
osteotomy and trans-articular release), or Group III (37 feet; Akin
osteotomy, supplementary axial Kirschner (K-) wire fixation, and
trans-articular release). Each group was then further subdivided
into severe and moderate deformities. The mean hallux valgus angle correction of Group II was significantly
greater than that of Group I (p = 0.001). The mean intermetatarsal
angle correction of Group III was significantly greater than that
of Group II (p <
0.001). In
Aims. Tibiotalocalcaneal (TTC) fusion is used to treat a variety of conditions affecting the ankle and subtalar joint, including osteoarthritis (OA), Charcot arthropathy, avascular necrosis (AVN) of the talus, failed total ankle arthroplasty, and
The Vantage Total Ankle System is a fourth-generation low-profile fixed-bearing implant that has been available since 2016. We aimed to describe our early experience with this implant. This is a single-centre retrospective review of patients who underwent primary total ankle arthroplasty (TAA) with a Vantage implant between November 2017 and February 2020, with a minimum of two years’ follow-up. Four surgeons contributed patients. The primary outcome was reoperation and revision rate of the Vantage implant at two years. Secondary outcomes included radiological alignment, peri-implant complications, and pre- and postoperative patient-reported outcomes.Aims

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

Background:. Various angles have been used to grade the severity of hallux valgus deformity. They are useful in surgical planning but do not correlate with symptom severity or improvement. We feel that there is a fundamental mismatch between the width of the forefoot and the width of the hindfoot and that this is more clinically relevant, we describe two techniques for measuring this. We aim to measure the degree of foot narrowing after surgery and moreover how this correlates to the severity of pre- and post operative outcomes. Methods:. 200 consecutive bunion operations were assessed with weight bearing radiographs. The HVA and IMA were measured according to standard practice. We also assessed forefoot width using two methods we have described. The first is the ‘Forefoot Width’ measured as a perpendicular to the midfoot (a technique we have previously validated). The ‘Foot Ratio’ is calculated as a function of the calcaneal width. Clinical outcomes were assessed using the MOXFQ and AOFAS. Results:. Bunion surgery narrows the osseous width of the forefoot. This narrowing can be by as much as 23 mm in cases with
Background:. The Chevron osteotomy is straightforward, requires less dissection and allows earlier rehabilitation than some other osteotomies. However it is generally perceived as unsuitable for
Introduction:. In a consecutive series of 71 arthroscopic subtalar arthrodeses performed between 2004 and 2011, 14 also involved arthroscopic decortication of the talonavicular joint (double arthrodesis) and 4 the subtalar, talonavicular and calcaneocuboid joints (triple arthrodeses). Methods:. We examined complications, union rates in all 18 patients and clinical outcomes in 16 for whom this was the sole procedure. Results:. Mean age was 62 (45–78). Two talonavicular joints failed to unite and a third patient suffered a diabetic Charcot midfoot neuro-arthropathy. These patients' outcomes were classified as poor. Two patients underwent planned major ankle or midfoot surgery in addition to arthroscopic double arthrodeses. These joints united but these patients were not included in the clinical review to avoid confounding outcomes. Mean follow-up for the remaining 13 patients was 4.4 (1.75–7.5) years. There were no immediate perioperative complications. All 4 patients with triple fusions united with good or excellent outcomes. The nine patients receiving double arthrodesis united with 8 good or excellent outcomes. The remaining patient reported good deformity correction and stability but disappointing pain relief, (classification poor). Conclusions:. Double and triple arthrodeses remain valid salvage options for painful arthrosis and
Introduction. Excision of prominent metatarsal heads for severe rheumatoid forefoot deformity is well established in clinical practice but results may deteriorate with time. The Stainsby forefoot arthroplasty however, recognises the pathological anatomy of the deformity and is designed to preserve the metatarsal heads by repositioning the plantar plates and forefoot fat pad underneath them. Design. A prospective case series observing the clinical outcomes and changes in pedobarograph patterns in rheumatoid arthritis patients with
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 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

Infected and deformed neuropathic feet and ankles are serious challenges for surgical management. In this study we present our experience in performing ankle arthrodesis in a closed manner, without surgical preparation of the joint surfaces by cartilaginous debridement, but instead using an Ilizarov ring fixator (IRF) for deformity correction and facilitating fusion, in arthritic neuropathic ankles with associated osteomyelitis. We retrospectively reviewed all the patients who underwent closed ankle arthrodesis (CAA) in Ilizarov Scientific Centre from 2013 to 2018 (Group A) and compared them with a similar group of patients (Group B) who underwent open ankle arthrodesis (OAA). We then divided the neuropathic patients into three arthritic subgroups: Charcot joint, Charcot-Maire-Tooth disease, and post-traumatic arthritis. All arthrodeses were performed by using an Ilizarov ring fixator. All patients were followed up clinically and radiologically for a minimum of 12 months to assess union and function.Aims

The relationship between hindfoot and forefoot kinematics is an important factor in the planning of ankle arthrodesis and ankle arthroplasty surgery. As more
Total ankle arthroplasty (TAA) has become the most reliable surgical solution for patients with end-stage arthritis of the ankle. Aseptic loosening of the talar component is the most common complication. A custom-made artificial talus can be used as the talar component in a combined TAA for patients with poor bone stock of the talus. The purpose of this study was to investigate the functional and clinical outcomes of combined TAA. Ten patients (two men, eight women; ten ankles) treated using a combined TAA between 2009 and 2013 were matched for age, gender, and length of follow-up with 12 patients (one man, 11 women; 12 ankles) who underwent a standard TAA. All had end-stage arthritis of the ankle. The combined TAA features a tibial component of the TNK ankle (Kyocera, Kyoto, Japan) and an alumina ceramic artificial talus (Kyocera), designed using individualized CT data. The mean age at the time of surgery in the combined TAA and standard TAA groups was 71 years (Aims
Patients and Methods
We hypothesized that there is no difference in the clinical and radiological outcomes using local bone graft We prospectively studied 28 calcaneal malunion patients (the study group) who were managed by subtalar distraction arthrodesis using local calcaneal bone graft. The study group included 16 male and 12 female patients. The median age was 37.5 years (interquartile range (IQR) 29 to 43). The outcome of the study group was compared with a control group of ten patients previously managed by subtalar distraction arthrodesis using iliac bone graft. The control group included six male and four female patients. The median age was 41.5 years (IQR 36 to 44).Aims
Patients and Methods
Congenital hallux varus had been a well-described condition for many years before acquired hallux varus as a condition arising from bunion correction was not described until 1935. In that year, McBride discussed this potential problem when describing this as a potential problem from his described technique, identifying possible mechanisms to prevent the disorder from occurring. Authors such as Joplin and Kelikian echoed the concept in the early 1960's, spawning a series of corrective procedures. Miller brought this to common practice in 1975, describing the tendon imbalance seen across the precarious 1. st. MTP joint. The first metatarsophalangeal joint moves in the sagittal plane, dorsiflexion and plantarflexion only. Four intrinsic muscles stabilize the digit, with the abductor and adductor hallucis taking the lion share of this function. The abductor tendon actually functions primarily as a plantarflexor of the first metatarsophalangeal joint 83% of the time (Thompson) due to its primary plantar location. This fact, in combination with the pronation generally seen in
