摘要： An intramedullary nail for use in combination with a proximal bone screw. The nail includes an elongated body having a proximal end and a distal end with a central axis extending between the proximal end and the distal end. The proximal end of the body has a transverse slot therethrough, the transverse slot therethrough with contour for allowing the proximal bone screw to be inserted through the transverse slot and through the proximal end of the body with the longitudinal axis of the proximal bone screw located at an angle to the central axis of the body of the nail within a range between an acute angle on either side of a plane extending transverse to the central axis of the body of the nail.

摘要： A moldable bone-implant material containing between about 65%-95% hard filler particles and a binder composed of between about 35%-5% of a biocompatible, biodegradable, thermoplastic polymer which has fluidic flow properties at or below about 60.degree. C. One preferred binder is polylactic acid having a molecular weight between about 400 and 5,000 daltons, and a preferred hard filler is hydroxylapatite. In use, the material is warmed to a temperature which allows molding, and the bone site is filled with the moldable material, which then forms a contour-fitting, semi-rigid implant. The implant retains its contour fit and acquires a rigid final state as the binder in the implant is gradually biodegraded and replaced through tissue ingrowth from the surrounding bone site.
摘要翻译：包含约65％-95％硬填料颗粒和由约35％-5％的生物相容性，可生物降解的热塑性聚合物组成的粘合剂，其具有在约60℃或低于约60℃的流动性。一种优选的粘合剂是分子量在约400和5,000道尔顿之间的聚乳酸，优选的硬填料是羟基磷灰石。在使用中，材料被加热到允许模制的温度，并且骨部位填充有可模制材料，然后形成轮廓拟合的半刚性植入物。植入物保持其轮廓拟合并获得刚性最终状态，因为植入物中的粘合剂通过从周围骨部位的组织向内生长逐渐生物降解和替代。
