Five-year followup of ankle joint distraction for post-traumatic chondrolysis in an adolescent: A case report

摘要: Chondrolysis is a process of progressive destruction the articular cartilage accompanied by pain and fibrous ankylosis, which may result in premature degenerative arthritis affected joint.6 The mechanism chondrolysis remains uncertain, although variety etiologies including mechanical injury, ischemia, increased intracapsular pressure, abnormal autoimmune response, abnormalities chondrocyte metabolism have been proposed.21 This disease entity most frequently observed hip joint, but has reported other joints knee, shoulder, ankle.2,11,21 mainstay treatment includes use nonsteroidal anti-inflammatory medications, protected weightbearing maintenance range motion joint.21 Recently, application joint distraction with hinged external fixator, termed “arthrodiatasis” used for hip.1,9,16 method provides controlled separation surfaces while allowing uniplanar across joint. Healing possibly related to decreasing load stimulation nourishment through constant flow synovial fluid.18,21 Articlulated appears be viable operative alternative young patients who would otherwise high likelihood poor radiographic functional outcome. Despite several recent reports ankle arthritis,18 we were unable find single report using this technique treating In report, an adolescent boy symptomatic posttraumatic was treated
