Abstract

• PURPOSE: To evaluate the clinical results of minimal incision and modified tension band wiring using 3.5mm cortical screw in the treatment of ankle fracture including displaced medial malleolar fractures MATERIALS AND METHODS: From March 1997 to May 2001, 77 patients were treated by modified tension band wiring using minimal incision about 4cm for medial malleolar fracture. RESULTS: According to Lauge-Hansen classification, there were 47 supination-external rotation type fractures (61%), 14 supination -adduction type fractures (18.2%), 10 pronation-external rotation type(12.9%), 6 pronation-abduction type fracture(7.8%). The average time to union was 12.5weeks. In the functional outcome (according to Meyer and Kumler), 71 patients(92%) showed excellent results. CONCLUSION: We concluded that modified tension band wiring using cortical screw proved effective fixation method in the treatment of the displaced medial malleolar fracture. The merits of this procedure are minimal incision about 4cm and preservation of blood supply on suprafracture area due to not injuried periosteum, stable fixation and early range of motion of joint, simple procedure and reduced surgical time.
• Key words: medial malleolar fracture, modified tension band wiring, cortical screw
