Raymond P Lee, Sally H S Cheng
Late stage ankle osteoarthritis often presents with debilitating pain. It is common to find osteophytes and loose body formation around the joint. Total ankle arthroplasty can preserve joint mobility and pain relieve for such patient. However, when trying to remove the osteophytes and loose bodies at the posterior ankle joint, there is risk of damaging posterior structures such as the neurovascular bundle during the procedure. We are presenting a case where the posterior loose bodies remained untouched during the operation, and patient showed spontaneous resolution of the lesions with time...

BACKGROUND: Sagittal implant malalignment after total ankle replacement (TAR) has been considered to be a possible cause for premature implant failure. In a prior study, the change over time of the tibiotalar ratio (T-T ratio), which is the ratio between the posterior longitudinal talar length and the full longitudinal talar length, was assessed in 66 TARs where an unconstrained, mobile-bearing implant was implanted. The analysis documented an increase in the T-T ratio between 2 and 6 months post-surgery (on average from 34...

BACKGROUND: Trauma to the talus can result in fracture, avascular necrosis and structural collapse. Treatment has been limited to surgical fusion and total ankle arthroplasty. Total ankle arthroplasty may not be an appropriate treatment for avascular necrosis while surgical fusion of the joint limits mobility. Custom-made implants have recently been used to address these limitations but have lengthy delays between injury and surgery and higher associated costs. A generic talar prosthesis available in various sizes may serve as a suitable alternative...

BACKGROUND: A new total ankle arthroplasty (TAA) system performed through a lateral approach provides direct visualization of the centre of rotation, allowing for accurate reconstruction of the joint alignment and less bone resection. Radiographic references are needed to describe deformities and plan the surgical procedures. The tibial slope is an important factor when treating malalignment. The aim of this study is to show if there is any difference regarding the post-operative tibial slope (β angle) measurement comparing a fixed-bearing TAA through a lateral approach and a mobile-bearing TAA through an anterior approach...

BACKGROUND: Total ankle arthroplasty remains a technically demanding surgery highly influenced by the operator experience. However, no consensus exists regarding the ideal number of cases that need to be performed before a surgeon is considered proficient. The aim of this study was to identify the learning curve of a specific replacement system with regards to intraoperative and postoperative outcomes. METHODS: The first 31 patients undergoing total ankle arthroplasty were examined...

BACKGROUND: We retrospectively evaluated the medium-term follow-up of bone grafting due to periprosthetic osteolytic lesions in ankles. METHODS: 34 ankles (32 patients) with total ankle arthroplasty (TAA) underwent re operation. Indications were large periprosthetic osteolytic lesions or continuous growing of the lesions. The osteolytic lesions were imaged by CT before reoperation and once a year after that. The mean CT follow-up after re operation was 3.8 years (range, 2-6...

BACKGROUND: The aetiology of heterotopic ossifications (HO) after total ankle arthroplasty (TAR) remains controversial. The aim of the study was to evaluate the prevalence and localisation of HO and the effect of alignment. METHODS: 88 TARs with a series of radiological controls and follow-up of 36 months were evaluated. Frontal and sagittal alignment parameters (alfa and beta angle defined by Hintermann) and tibial coverage were evaluated. RESULTS: The prevalence and grading of HO increased over time, mostly in the posterior gutter...

BACKGROUND: A new design of 3-part ankle replacement was developed to achieve compatibility with the natural ligaments by allowing certain fibers to remain isometric during passive motion. METHODS: We evaluate 75 ankle prostheses implanted from July 2003 to December 2008, at a mean follow-up 6.5±1.1years (range 5-9 years). The mean age at surgery was 62±13years (range 29-82). RESULTS: The mean AOFAS scores achieved at pre-op and at last follow-up were respectively 37±5 (23-45) and 78±8 (64-98)...

BACKGROUND: Total ankle arthroplasty (TAA) is becoming an increasingly utilized procedure for the management of end-stage ankle arthritis. Elderly patients are the fastest growing segment of the population in the western world, creating a unique challenge to the health economics of our era. Determining if elderly patients with end-stage ankle arthritis demonstrate the same improvements in clinical outcomes and functional measures of gait following TAA would be valuable. This can aid to evaluate the utilization of TAA in this enlarging cohort of our population...

BACKGROUND: Failed hallux valgus surgery may result in residual or recurrent hallux valgus, and as well transfer metatarsalgia. The present technical tip concerns the combination of fusion of the first metatarsophalangeal (MTP) joint and lengthening of the first metatarsal (MT) through a scarf osteotomy. MATERIALS AND METHODS: Six patients underwent the presented technique, all for the indication of failed hallux valgus surgery with shortening of the first MT and degenerative changes in the 1st MTP joint...

We report a case of a complex limb salvage ankle arthrodesis in a patient with Charcot arthropathy. A step-cut osteotomy was performed in order to tackle the issues of anterior tibial bone loss; worsening leg length discrepancy; soft tissue contraction; joint instability and high risk of non-union. The construct formed by the step-cut allowed for the preservation of good bone stock; avoidance of further limb shortening; increased torsional stability and increased surface area for bony union. This resulted in a patient with a stable, plantigrade foot appropriate for footwear...

An irreducible ankle-fracture dislocation characterized by the dislocation of the proximal fragment of the fibula posteriorly to the tibial tubercle is defined as "Bosworth injury". In the present report it is described, for the first time in literature, a complex case where the Bosworth injury was associated to a tibial plafond fracture: the proximal fibular fragment was entrapped between the tibial pilon and the fractured posterior tibial tubercle, which acted as a clamp, thus avoiding ankle reduction. Due to the presence of the tibial fracture, it was not possible to observe the typical radiological signs of Bosworth injury and therefore two unsuccessful reductions were attempted before performing a CT scan that revealed the complexity of the case, that required an immediate ORIF procedure to prevent the onset of complications...

T H Lui, L L LiYeung
BACKGROUND: Metatarsophalangeal joint instability of the lesser toe can cause acquired toe deformity. Plantar plate deficiency is the major pathology. Plantar plate repair can stabilize the joint but may result in iatrogenic transverse plane toe deformity in correction of claw toe deformity. Limited toe extension can be resulted after correction of crossover toe deformity by plantar plate tenodesis and extensor digitorum brevis transfer. A modification of the technique is proposed. MATERIALS AND METHODS: The clinical outcomes of 10 patients with the modified procedure performed were assessed...

Ziyaad Mayet, Hooman Eshraghi, Paulo N F Ferrao, Nikiforos P Saragas
BACKGROUND: Barbed sutures represent a novel technique for wound closure. By distributing tension forces across the length of a wound, it results in better wound healing. A recent article from Chowdhry et al. cautioned against the use of barbed sutures in foot and ankle surgery. Our experience with the Quill(®) (Angiotech, Vancouver, BC) barbed suture, showed a more positive outcome. MATERIALS AND METHODS: 123 surgical wounds were prospectively followed up after closure with a bidirectional barbed suture...
