In unstable pertrochanteric fractures of the femur a high bending strain and much load lies on the medial part of the bone. The connecting osteosynthesis takes off this load and immediately guarantees a high stability. Clinical experiences with 44 cases of connecting osteosynthesis - among them 35 per-and subtrochanteric fractures of the femur-show, that in 11 cases complications due to the fractures occurred (breaking of the implant, pseudarthrosis etc.) These complications are probably due to a delayed healing caused by bone cement penetrating into the area of the fracture. It is recommended to use an autologous cancellous bone graft. Indications for the compound osteosynthesis are only unstable pertrochanteric fractures in old patients in poor general condition and a short life-expectancy, and fractures in patients with diffuse metastases.
在不稳定型股骨转子间骨折中，高弯曲应变和大量负荷集中在股骨内侧部分。连接性骨合成可减轻此负荷并立即确保高度稳定性。44例连接性骨合成的临床经验——其中35例为股骨转子周围和转子下骨折——显示，有11例发生了骨折相关并发症（植入物断裂、假关节形成等）。这些并发症可能是由于骨水泥渗入骨折区域导致愈合延迟所致。建议使用自体松质骨移植。复合骨合成的适应证仅为一般状况较差、预期寿命较短的老年患者的不稳定型股骨转子间骨折，以及伴有弥漫性转移的患者的骨折。
