Distraction arthroplasty for post traumatic osteoarthritis of the ankle joint: A case report

Abstract

Treatment modalities for post traumatic osteoarthritis of the ankle joint are a challenge for orthopaedic surgeons worldwide. Ankle distraction arthroplasty is a useful alternative to arthrodesis or total ankle arthroplasty and is especially useful in younger individuals who are reluctant towards an ankle fusion. It involves the use an external fixator to distract and thereby mechanically offload the ankle joint and simultaneously permit a stable range of motion. The purpose is to allow intermittent intra-articular flow of synovial fluid and to relieve the mechanical stresses on the cartilage. The procedure is extremely rewarding for individuals seeking an alternative to ankle arthroplasty or fusion.
