Abstract

Displaced intraarticular fractures of the calaneus require operative intervention to restore the anatomy of the bone, which in turn is the requirement for recovery of subtalar joint mobility. To evaluate the complex contour of calcaneal anatomy, a classification for intraarticular calcaneal fractures was used, based on standardized coronal and transverse computed tomography scans of os calsis. From January 1993 to December 1994, intraarticular calcaneal fractures of 47 cases treated in Korea Veterans Hospital were analysed preoperatively with C.T. scan and classified by Sandersclassification system. And clinical evaluation of the patients was done by Maryland Foot Score postoperatively. The result were as follows:Type I fractures were found in 10 cases. 25 cases of 47 cases were classified as type II and subdivided as II A in 13 cases, II B in 6 cases, II C in 6 cases. Type III fractures were found in 8 cases and subdivied as III AB in 4 cases, III BC in 3 cases, III AC in 1 case. Type IV fractures were found in 4 cases. This classification aids a surgeon to make perioperative decision, because it has prognostic significance.
