PURPOSE: To present the result of retrograde Ender pinning technique for treatment of comminuted segmental fracture of the proximal tibial shaft. MATERIALS and METHODS: From 1994 to 1998, we treated twenty-one cases of the comminuted segmental proximal tibial shaft fracture with the retrograde Ender pinning technique. We have followed up the clinical results. RESULTS: The clinical bone union time was average eleven weeks, and the radiologic bone union time was average nineteen weeks. CONCLUSIONS: In the treatment of comminuted segmental proximal tibial shaft fracture, the retrograde Ender pinning technique is useful. The method improves fixation of the proximal fragment, is simple and effective, provides good fixation of the tibia in patients in whom stabilization of several fractures is required, and can be used for fixation of tibial shaft fracture with soft tissue damage.
