Twelve interarticular fractures of the calcaneus were treated by the modifications of Kashiwagi's method. The terms of the follow-up were average three years and two months. The results are satisfactory. The fractures involving the thalamic portion of calcaneus is rarely due to direct vertical compression and usually due to a shearing stress combined with compression in a rotatary direction. By the rotation of the fragment in normal position the fundamental deformity is corrected and the tuberjoint angle is restored. We think that the anatomical reduction of the fractures produces good result.
