[Fracture-dislocation of the calcaneus. Apropos of 4 cases]

The authors have observed four cases of a rare condition of fracture-dislocation of the calcaneus. The fracture line was in the sagittal plane and there were only two fragments. An anterior and medial fragment maintained its normal relationship with the talus whilst the posterior and lateral fragment became dislocated laterally underneath the fibular malleolus. Treatment should always be surgical by open reduction and screw fixation. Two cases out of four were not operated upon and these have poor results.
