摘要
从１９８８年１月～１９９３年１月应用经皮空心加压螺纹子母钉治疗股骨颈骨折１４２例，随访平均３４个月，治疗结果优良率９２．９％（１３２／１４２），６例不连接（４．２％），４例缺血性坏死（２．９％），效果满意。这种螺纹钉中央有孔道，引道直径为１．５～２．５ｍｍ，螺纹分为１０ｍｍ、２０ｍｍ及２５ｍｍ三种，钉长度有８０～１２０ｍｍ规格，共九个品种，供选择应用。经生物力学测试，母钉弹簧具有０．６～１．２Ｋｇ的压力，子钉具有０．５Ｋｇ的压力，符台临床应用标准，这种手术方法安全、简单，骨不连发生率低。
AbstractFrom Jan 1 988 to 1 993. 142 cases of femoral neckfractrure were managed with percutaneous compres-sion screw complex technique. Follow-up averaged 34months. the results were quite satisfactory:92. 9 per-cent (1 32/142) of the cases ranked as good or excel-lent. while non-union and avascular necrosis of thefemoral head occured in the remaiming 6(4.2%) and 4(2.9%) cases respectively.There was a tunnel inside the screw. with an in-ner diameter of 1.5～2. 5 mm.The screwthread were10.20 or 25 mm in length. The length of the screwvaried from 80 to 120 mm. there were 9 types of screwin different sizes for selection. The biomechanics testshowed us that the spring of the main-screw couldstand 0.6～1. 2kg of pressure. while that of the sub-screw could stand 0. 5kg. All met the clinical applica-tion standards, The method was found to be safe andsimple with a low incidence of non-union.
