【摘要】 目的　探讨HanssonPin治疗股骨颈骨折的疗效。方法　临床治疗 39例 ,并作生物力学测试。结果　全部病例得到随访 ,时间 4～ 36个月 ,平均 2 3个月。骨性愈合 31例 ,其中 12例有滑针、股骨颈缩短表现 ,半年内出现滑针、塌陷移位 3例 ;股骨头缺血性坏死 5例。生物力学性能显示HanssonPin的承力效果优于骨圆针。结论　HanssonPin作为股骨颈内固定操作简单 ,但术后早期负重行走滑针率较高更多还原

【Abstract】 Objective To investigate the clinical therapeatic effectiveness of the femoral neck fracture treated by Hansson pin and biomechanical test was carried out in cadaveri femoral specimens Methods Thirty nine cases of femoral neck fracture were treated by Hansson Pin and biomechanical test was carried out in cadaveri femoral specimens.Results All patients were followed up for an average duration of 23 months The results show that 31 cases healed up, as a result of pins sliding, so that femoral neck was shortening in 12 cases; femoral head collapsed was found in 3 cases and ischemic necrosis of femoral head appeared in 5 cases The biomechanical character of Hansson pin is only better than round pin Conclusion Hansson pin is easy to be used , but the rate of sliding pin is 38 46%,which is resulted from allowing the patient to wear early更多还原
