Avulsion fractures of the calcaneal tuberosity are rare injuries in extraarticular fractures of thecalcaneus and were resulted from a separation of a shell of the posterior portion of the os calcisdue to the pull of the Achilles tendon. Importance of anatomic reduction for the restoration offunctional length of Achilles tendon were emphasized by many authors in the treatment of thefractures. The purpose of this study is to evaluate the results of operative treatment in avulsion fracturesof the calcaneal tuberosity and to analyse the results in accordance with various prognosticfactors. This article has reviewed a series of 6 avulsion fractures of calcaneal tuberosity, treatedfrom March 1991 to November 1996. The results were as follows ; 1. In case of avulsion fracture of os calcaneus, open reduction and internal fixation wasneeded for the accurate anatomical reduction and maintenance of firm internal fixation. 2. The method of operative treatment was not significant influencing factor on the treatmentresult, however, it is more convenient to fix when cannulated screws were used because of thecompressive effect on the fracture site. 3. Complications included superficial skin necrosis in one case, which resulted from thecompression of bony fragment in case of avulsion fracture and another, wire fixation failurebecause of bone resorption resulted from wide soft tissue dissection.
