目的：探讨镍钛形状记忆合金聚髌器在髌骨骨折治疗中的疗效。方法36例髌骨骨折应用镍钛形状记忆合金聚髌器内固定治疗。结果经平均13.3月（12～24个月）的随访，所有病例骨折均完全愈合，未发现聚髌器断爪、松动、戳破皮肤、骨折移位、骨不连及关节面阶梯等现象，且关节功能恢复良好。结论镍钛形状记忆合金聚髌器治疗髌骨骨折，固定可靠，疗效确切，符合髌骨骨折内固定及术后功能锻炼的生物力学要求，使髌骨骨折的治疗有了新的可供选择的方法。“,”Objective To study the treatments and effects of fractures of patel a with Ni-Ti-shaped memory al oy.Method 36 patients of fractures of patel a were treated with Ni-Ti-shaped memory al oy.Result The average fol ow-up time was 13.3 months(12~24 months).Al cases were cured with bone unions. No breakage or loosening of the holder,displacement of fractured bone or articular surface ladder were found.ConclusionThe method is safe and reliable,consistent with biomechanical,requirements of the internal fixation of patel ar fracture.The internal fixation of patel ar fracture has a new and alternative method.
