Transmalleolar Approach for Arthroscopy-Assisted Headless Screw Fixation of an Osteochondral Talar Dome Fracture.

Displaced osteochondral fractures of the body of talus quite often require a malleolar osteotomy to gain access to the fracture fragment during internal fixation. We describe a case report in which access to a displaced osteochondral fracture of the lateral talar dome was achieved using an arthroscopy-assisted fibular tunnel approach. This technique resulted in satisfactory fracture healing and a satisfactory clinical outcome.

Poncet's disease (tubercular rheumatism) with primary involvement of the foot - A case report.

We present a rare case with primary tubercular involvement of the foot, accomapanied by a reactionary (aseptic) effusion in the knee. The diagnosis was delayed due to unusual presentation and also because of failure to elicit a detailed history. Incision and drainage of the foot abscess and antitubercular drug therapy resulted in satisfactory control of tubercular infection. Polyarticular presentation may not always signify active tubercular focus in every joint; it may reflect reactive synovitis known as Poncet's disease, which resolves with multidrug antitubercular therapy.A multidispilinary approach should be adopted and chest physicians, rheumatologists and orthopaedic surgeons should work in close association to correctly diagnose and treatthis condition.

Early clinical and radiological results of total knee arthroplasty using patient-specific guides in obese patients.

PURPOSE: Total knee arthroplasty (TKA) is a challenging procedure in patients with a high body mass index (BMI). The aim of our study was to assess the outcome and accuracy of restoration of mechanical alignment in TKA using patient-specific guides (PSG) involving patients with high BMI. MATERIALS AND METHODS: Patients with BMI of 30 or above were enrolled in the study. The mean age of the patients was 65.15 years. The study comprised of 46 males and 54 females. Total knee arthroplasty was planned after a pre-operative MRI and long leg x-ray films using customized PSG. RESULTS: Of the 105 knees (100 patients) in the study, average BMI was 35.42 kg/m(2) (30-56). Twenty patients (20 %) had class III obesity (≥40 kg/m(2)). The average blood loss and operative time were 236.1 ml (range 50-700 ml) and 92.2 min (65-130 min), respectively. The average post-operative mechanical axis was noted to be 1.85° varus (range 4° valgus to 6° varus). Eighty-eight patients (86.27 %) had mechanical alignment within 3° of neutral. There were no adverse intraoperative events. One patient had deep infection that required a two-stage revision. The average post-operative range of motion at 1-year follow-up was 105.8° (range 80°-130°). CONCLUSION: Patient-specific guides technology restores the coronal mechanical axis reliably in obese patients without adversely affecting outcomes. Our short-term follow-up has shown favorable outcomes. Surgeons should use these customized jigs as a guide and adjust the size of components, alignment and rotation according to normal surgical principles.

Anterior dislocation of the tibio-talar joint without diastasis or fracture--a case report.

We present a 27-year-old man with pure anterior dislocation of the ankle joint following a fall from height. There were no accompanying fractures in and around the ankle joint. The injury was initially missed on clinical examination in view of minimal ankle deformity. The patient was managed conservatively with closed reduction and plaster immobilisation. The case report highlights the importance of early diagnosis and management of anterior ankle dislocation to obtain good functional outcome. A review of the literature on this rare injury is also presented.
