Methods 68 cases with femoral peritrochanteric fracture from January, 2002 to December, 2007. 25 were treated by Gamma nail, 25 of them were treated by DHS, DCS and 18 of them were treated by HCS.

2002年1月～2007年12月收治的股骨转子间骨折并通过手术治疗的68例，采用Gamma钉固定25例、滑动加压鹅头钉固定25例与空心加压螺钉固定18例。

These three internal fixations of femoral peritrochanteric fracture were differ. For example, Gamma nail is less harmful, better clinical treatment, shorter in shape and stronger in anti-hip inversion. DHS, DCS have a better treatment and are stronger in anti-hip inversion but more harmful and excessive bleeding, and HCS, which is named Minimally Invasive Surgery, is the least harmful, less bleeding, suitable for old patients and the patients of tolerance of poor operation, but poor in anti-hip inversion.

3种不同方法内固定治疗转子间骨折具有各自的特点，Gamma钉具有手术损伤小及良好的临床疗效力臂短对抗髋内翻的能力强；滑动加压鹅头钉具有良好的临床疗效及相对坚强的抗内翻能力，但手术损伤相对较大，失血量较大；空心加压螺钉固定的手术损伤最小，属于微创手术方法，可经皮完成，手术出血少，适用于高龄及手术耐受性差的患者，但抗髋内翻的能力最差。
