改良Allis法治疗合并PipkinⅠ、Ⅱ型骨折的髋关节后脱位

Value of modified Allis technique in closed reduction of posteriorly dislocated hip with Pipkin I / IIfracture

目的探讨改良Allis法治疗合并PipkinⅠ、Ⅱ型骨折的髋关节后脱位中的应用价值。方法2005年1月1日至2010年12月31日河北医科大学第三医院创伤急救中心98例合并PipkinⅠ、Ⅱ型骨折的髋关节后脱位病例，统计Allis法闭合复位成功率作为对照组。前瞻性研究36例确诊为合并PipkinⅠ、Ⅱ型骨折的髋关节后脱位病例，作为研究组。研究组应用Allis法和改良Allis法闭合复位，统计复位成功率，比较研究组和对照组两种复位方法成功率。通过影像学分析部分病例Allis法复位困难的原因。结果对照组98例，其中32例未能成功闭合复位，手法复位成功率67．3％。研究组36例，传统Allis法复位成功率69．4％，加用改良A11is法复位，成功率97．2％。影像学分析显示，Allis法复位成功组股骨头骨缺失小于Allis法复位失败组。结论对于复位困难的合并PipkinⅠ、Ⅱ型骨折的髋关节后脱位，改良Allis法可以满意复位。

Objective To explore the value of modified Allis technique in closed reduction of posteriorly dislocated hip. Methods For the control group, 98 cases of dislocated hips with Pipkin I / II fracture were studied retrospectively and their success reduction rates analyzed. For the experimental group, 36 cases with similar injury were studied prospectively. And the modified Allis technique was used and the success reduction rates were analyzed. Results Among the control group, 32 cases were reduced with a success rate of 67.3%. The success rate was 69.4% for the experimental group. And 97.2% of those unresponsive to the Allis technique were all successfully reduced by the modified Allis technique. Conclusion The modified Allis technique is efficacious for posteriorly dislocated hips with Pipkin I/II fracture.
