Abstract The operative treatment of intraarticular calcaneal fractures has three principal aims: restoration of height, length, and width of the calcaneus, reconstruction of the subtalar and calcaneocuboid joint surfaces, and stable osteosynthesis using an H-plate or screws. In 68\% of the cases, the sustentacular fragment was the key to open reduction, making the medial approach mandatory. In complex fractures, a lateral approach is added. In "blow-out" fractures or cases with comminution of the sustentacular fragment, an extended lateral approach only is used. For precise preoperative planning of roentgenograms in three planes, four Brodén's views and axial plus coroneal or three-dimensional computed tomography scans are required. From July 1983 to July 1990, 157 intraarticular calcaneal fractures were treated by open reduction. The results in 123 cases are 61\% good or excellent, 32.5\% satisfactory, and 6.5\% poor. The following early complications occurred: superficial wound edge necrosis (8.3\%), hematoma (2.5\%), nonunion (1.3\%), and infection (1.9\%). Four patients (3.3\%) in the follow-up group have developed degenerative changes severe enough to require subtalar fusion. To facilitate the comparison of results, new fracture classification and follow-up scoring systems have been devised.
