Total ankle replacement in patients with end-stage ankle osteoarthritis: clinical results and kinetic gait analysis.

Background: Total ankle arthroplasty is being used more frequently as an alternative for arthrodesis in final stages of ankle osteoarthritis. However, there are few studies which describe the biomechanics of gait of these patients.

Methods: Between March 2006 and May 2011, 17 patients (n=18 ankles) suffering end-stage osteoarthritis of the ankle who underwent an ankle replacement (HINTEGRA) were evaluated retrospectively.

Osteochondritis of the hallux sesamoid bones.

Osteochondritis of the sesamoid bones is an infrequent condition which may affect both the medial and lateral hallux sesamoids. Those cases refractory to conservative treatment can be satisfactorily solved by carrying out its surgical excision. We present a literature review about its causes, pathophysiology, the diagnostic methods and the treatments options.
