单纯后入路内固定治疗累及四边体和前柱的髋臼骨折

目的回顾分析我院治疗的累及四边体和前柱的髋臼骨折病例,探讨采用单一改良K-L入路同时治疗累及四边体和前柱的髋臼骨折方法。方法在20例髋骨标本上测量髋臼后壁的宽度,并通过测量前倾的角度探索最佳向前置钉角度。对2000年1月～2008年5月以来共15例累及四边体和前柱的髋臼骨折患者采用单一改良K-L后入路同时固定髋臼前后柱骨折,术后功能锻炼。结果髋臼后壁宽度在47～52mm之间。在髋臼后壁的外2/5区域,向前植入螺钉均进入髋臼内;在髋臼后壁的中间1/5区域,向外倾斜15°置钉,有6例部分进入髋臼内;在髋臼后壁的内2/5区域,向前倾斜10°置钉,螺钉无一进入关节内,其远端可以从前柱穿出。随访9～27月,按Matta标准评价髋臼复位质量:解剖复位11例,满意复位3例,不满意复位1例,优良率93.3%。髋关节功能参照改良的Merled,Aubigne标准:优8例,良4例,可2例,差1例,优良率80.0%。结论充分的术前计划、恰当的手术时机、充分的术野暴露以及良好的术后锻炼是治疗髋臼骨折的有效方法。

Surgical treatment of acetabular fractures involved anterior column and quadrilateral area with single modified Kocher-Langenbeck (K-L) approach

Objective To summarize retrospectively the clinical therapeutic and to investigate the treatment method of acetabular fractures involved anterior column and quadrilateral area with single modified Kocher-Langenbeck(K-L)approach.Methods 20 acetabular posterior wall of hip bone sample were measured and best anteverted angles of nail insertion were designed.From Jan.2000 to May.2008,15 patients with acetabular fractures involved anterior column and quadrilateral area were treated by single modified Kocher-Lang...
