TMTJ fusion is performed for arthritis or painful deformity. K-wire and trans-articular screws are usually used to stabilize the joints. We present our experience with LP for TMTJ fusion in first 100 joints. 100 TMTJ in 74 patients were fused and stabilised with LP between January 2007 and December 2010. The indication was Lisfranc arthritis and hallux valgus. Iliac crest bone autograft was used in 64 joints. Auto graft was used in 22/53 first TMT fusions. All patients post-operatively had below knee plaster immobilization and protected weight bearing walking for first 6 weeks. Clinical and radiological surveillance continued until bone. AOFAS midfoot scale was used as outcome measure. There were 18 male and 56 female patients with average age of 51 (14 -68). AOFAS midfoot scale improved 42% for pain, 30% for function and 53% for alignment. Average AOFAS overall score improved from 30 pre-op to 67 post op. 95 joints had clinical and radiological fusion. 1 patient needed removal of metalwork and 3 had delayed wound healing and 4 had radiological non- . All non- s were in 1st TMTJ where bone graft failed and were revised. None of the lesser ray TMTJ had non- . Average satisfaction score was 7 out of 10. 86% said they would recommend it to a friend and 91% would have it again.Patients and methods
Results
When a total ankle arthroplasty (TAA) fails, it can be converted to a fusion or a revision arthroplasty. Despite the increasing numbers of TAAs being undertaken, there is little information in the literature about the management of patients undergoing fusion following a failed TAA. The primary aim of this study was to analyze the survival of fusions following a failed TAA using a large dataset from the National Joint Registry (NJR). A data linkage study combined NJR and NHS Digital data. Failure of a TAA was defined as a fusion, revision to a further TAA, or amputation. Life tables and Kaplan-Meier graphs were used to record survival. Cox proportional hazards regression models were fitted to compare the rates of failure.Aims

We report the medium-term outcomes of a consecutive series of 118 Zenith total ankle arthroplasties (TAAs) from a single, non-designer centre. Between December 2010 and May 2016, 118 consecutive Zenith prostheses were implanted in 114 patients. Demographic, clinical, and patient-reported outcome measures (PROMs) data were collected. The endpoint of the study was failure of the implant requiring revision of one or all of the components. Kaplan-Meier survival curves were generated with 95% confidence intervals (CIs) and the rate of failure calculated for each year.Aims
Methods
As it remains unproven that hypermobility of
the first tarsometatarsal joint (TMTJ-1) is a significant factor
in hallux valgus deformity, the necessity for including arthrodesis
of TMTJ-1 as part of a surgical correction of a hallux valgus is
questionable. In order to evaluate the role of this arthrodesis
on the long-term outcome of hallux valgus surgery, a prospective,
blinded, randomised study with long-term follow-up was performed,
comparing the Lapidus procedure (which includes such an arthrodesis)
with a simple Hohmann distal closing wedge metatarsal osteotomy. The
study cohort comprised 101 feet in 87 patients: 50 feet were treated
with a Hohmann procedure and 51 with a Lapidus procedure. Hypermobility
of TMTJ-1 was assessed pre-operatively by clinical examination.
After a mean of 9.25 years (7.25 to 11.42), 91 feet in 77 patients
were available for follow-up. There was no difference in clinical
or radiological outcome between the two procedures. Also, there
was no difference in outcome between the two procedures in the subgroup
clinically assessed as hypermobile. This study does not support
the theory that a hallux valgus deformity in a patient with a clinically
assessed hypermobile TMTJ-1
Background. Lisfranc/midfoot injuries are complex injuries with a reported incidence of 1 in 55000 in literature and frequently overlooked. But, recently they are becoming more commonly diagnosed with advent of CT scan and examination under anaesthesias (EUA) for suspicion fractures. Here we present a case series results of a single surgeons experience over the last 6 years. Methods. Retrospective review of 68 patients treated by a single surgeon over the last 6 years. Injuries were diagnosed on plain Xrays, clinic examination. Any suspicious injury were further assessed by a CT scan, all injuries were confirmed by EUA and treated with open reduction and internal fixation within 4 weeks of injury. Post-operative immobilisation in full cast for 6 weeks then a removal boot with non-weight bearing for a total of 3months. They were followed up regularly initially at 3, 6 and 12months. At final review the following data was collected: clinical examination, plain x-ray looking for: late deformity, signs of OA in Lisfranc

Hindfoot arthrodesis with retrograde intramedullary nailing has
been described as a surgical strategy to reconstruct deformities
of the ankle and hindfoot in patients with Charcot arthropathy.
This study presents case series of Charcot arthropathy patients
treated with two different retrograde intramedullary straight compression
nails in order to reconstruct the hindfoot and assess the results
over a mid-term follow-up. We performed a retrospective analysis of 18 consecutive patients
and 19 operated feet with Charcot arthropathy who underwent a hindfoot
arthrodesis using a retrograde intramedullary compression nail.
Patients were ten men and eight women with a mean age of 63.43 years
(38.5 to 79.8). We report the rate of limb salvage, complications requiring
additional surgery, and fusion rate in both groups. The mean duration
of follow-up was 46.36 months (37 to 70).Aims
Patients and Methods
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.
