Intramedullary rigid nailing has been used to treat diaphyseal fracture of tibia, but with improvement of practical technical ideas, especially development of interlocking transverse screw, the indication of intramedullary nailing for tibial fracture became expanded to the fractures occurred 3cm proximal to the ankle joint. We treated 34 distal tibial fractures from Mar. 1992 to Feb. 1995 and followed up at least more than one year. The results of treatment were as follows ; 1. Time for union was 11.3 weeks in closed fracture group and 19 weeks in open group. 2. According to the functional classification of Klemm and Borner, excellent and good results were obtained in 30 cases(94.1%). 3. Complications developed in 7 cases which include ankle motion limitation, angular deformity, delayed union.
