The implantation of an intramedullary transcutaneously conducted femur prosthesis presents a rather new procedure for the rehabilitation of above-knee amputated patients. The aim of the so-called endo-exo prosthesis is to avoid the well-known problems at the interface between the sleeve of the prosthesis and the soft tissue coat of the femur stump which often impedes an inconspicuous and harmonic gait.
The company ERSKA Implants in Lübeck/Germany has developed an intramedullary femur prosthesis with a spongiosa metal-configurated relief surface which, when implanted cementless, enables a secure osseointegration and allows a more direct transmission of muscle power to the lower leg prosthesis. A minimum length of 16-18 cm and a sufficient soft tissue coverage of the femur stump is needed. The problems at the perforation point of the implant through the soft tissue coat can be handled or even be avoided and they do not necessarily provoke an intramedullary infection.
We report on 30 cases that were operated between 1999 and 2008. The design of the prosthesis, aspects of the operative procedure and latest results are presented.
植入经皮传导的股骨骨髓腔内假体是一种用于膝上截肢患者康复的全新手术方法。所谓的内外侧假体的目的是避免在假体套筒与股骨残端软组织包膜之间的界面出现众所周知的问题，这些问题常常妨碍步态自然和谐。
德国吕贝克的ERSKA植入物公司研发了一种具有松质金属构型减压面的股骨骨髓腔内假体，该假体在非骨水泥植入时能够实现牢固的骨整合，并能使肌肉力量更直接地传递至小腿假体。需要股骨残端的最小长度为16 - 18厘米，且要有足够的软组织覆盖。植入物穿过软组织包膜的穿孔点处的问题可以得到处理甚至避免，而且不一定会引发骨髓腔内感染。
我们报告了1999年至2008年间接受手术的30例病例。介绍了假体的设计、手术操作要点及最新结果。
