股骨近端髓内钉和动力髋螺钉治疗股骨粗隆间骨折的临床疗效观察

Clinical observation of PFN-A and DHS on the treatment of intertrochanteric fracture

目的通过比较目前治疗股骨粗隆间骨折常用的两种内固定系统：股骨近端髓内钉（PFN-A）和动力髋螺钉（DHS）的临床疗效，评价两者治疗股骨粗隆间骨折的优劣。方法临床上均采用闭合牵引复位，分别用PFN-A和DHS治疗股骨粗隆间骨折患者53例和67例，比较其手术难易程度、疗效及术中、术后并发症。结果PFN-A治疗股骨粗隆间骨折的术中、术后并发症少于DHS。结论PFN—A设计合理，具有操作简单、抗旋转确实、手术创伤小、出血量少、并发症少等优点，是治疗股骨粗隆间骨折的理想内固定物之一。

Objective To compare the current treatment of intertrochanteric fracture fixation commonly used in the two systems：proximal femoral nail （PFN-A） and the dynamic hip screw （DHS） of clinical efficacy and evaluate the treatment of the two intertrochanteric fracture of the gifted bad. Methods The clinical use on closed reduction and traction,respectively PFN-A with DHS and the treatment of intertroehanteric fracture patients with 106 cases and 115 eases ,compared with its ease of operation, and the effect of surgery, postoperative complications. Results The clinical material demonstrated that in after PFN-A treatment thighbone thick prosperous bone fracture technique,technique,the complication is short in DHS. Conclusion PFN-A well-designed,with simple anti-rotation indeed,surgical trauma,less bleeding,fewer complications ,etc. ,is the treatment of intertrochanteric fracture fixation one of the ideal.
