目的：探讨加长Ⅱ代亚洲型股骨近端防旋髓内钉(简称加长 PFNA-Ⅱ)治疗股骨中上段复杂多段骨折的近期疗效。方法应用加长 PFNA-Ⅱ治疗26例股骨中上段复杂多段骨折患者,对术后及随访后的疗效、安全性及功能恢复进行评估。结果患者均获随访,时间6~18个月。手术时间40~90(58±13．6)min,术中失血量50~160(77．8±25．6)ml。围手术期无严重并发症或原有合并症加重。末次随访时均达到临床愈合标准,按 Harris 髋关节功能评分标准：优17例,良 6例,中3例。无髋内翻、内置物切出、断裂、周围骨折及深静脉血栓形成等并发症发生。结论加长 PFNA-Ⅱ的设计符合亚洲人股骨近端的解剖特点,治疗股骨中上段复杂多段骨折中创伤小,生物力学特性好,功能恢复快,并发症少。

Objective To investigate the clinical effect of long proximal Asia femoral nail antrotation(Ⅱ) (PFNA-Ⅱ) in proximal-middle long-segment complicated femoral fractures. Methods 26 cases were treated with PFNA-Ⅱ, the clinical effects were evaluated according to Harris criteria and radiological examinations. Results All patients were followed up for 6 ~ 18 months. The operating time of all cases was 40 ~ 90 (58 ± 13. 6) minutes,and the mean blood loss during surgery was 50 ~ 160 (77. 8 ± 25. 6) ml. No serious complications and aggravation occurred during perioprative period. According to Harris criteria, the clinical results were excellent in 17 cases, good in 6 and fair in 3. No caxa vara,infection, cut out or breakage of the implants,secondary fractures or DVT occurred. Conclusions Long PFNA-Ⅱ is better suited for the proximal femur of Asian patients. Long PFNA-Ⅱ is an effective and minimally invasive method for proximal-middle long-segment complicated femoral fractures,which is better method with high fix-ation strength, early functional recovery, a high rate of bone union, compatible biomechanics characteristics and less complications.
