Abstract

• Malunion of calcaneal fracture results in most of long-term complications such as pain and limitation of motion at hindfoot. Though it is reported that patients symptoms continue to improve during following years, some patients are disabled espicially due to pain. Among the source of pain following malunited calcaneal fracture, traumatic arthritis of subtalar joint, peroneal tendinitis with or without dislocation of tendons, compression neuropathy, and other sequelae were believed to be responsible. The authors report the result of surgical treatment of 9 patients with malunited calcaneal fracture, who had stenosing tenosynovitis(3 cases), and recurrent dislocation of peroneal tendon(6cases). key words; peroneal tendon, stenosing tendinitis, dislocation, malunion, calcaneus Excision of bone mass from the lateral wall of calcaneus and adhesiolysis relieved symptoms of stenosing synovitis. Zoellner and Clancy technique of deepening peroneal tendon groove and reconstruction of peroneal retinaculum using periosteal flap were supplemented for dislocation of peroneal tendon. Among nine patients, four needed subtalar arthrodesis. The results were favorable.
