摘要 目的探讨全髋关节置换术后髋臼外展角与后脱位的相关性。方法收集2017年1月至2018年12月湖北省宜昌市第一人民医院行初次人工全髋关节置换术患者377例(419髋),术后发生脱位20例。根据术后X线片检查髋臼唇外展角分为四组:髋臼唇外展角<40°组、髋臼唇外展角≥40°~50°组、髋臼唇外展角>50°~60°组、髋臼唇外展角>60°组。结果髋臼唇外展角<40°131例,发生脱位7例,脱位率5.3%;髋臼唇外展角≥40°~50°174例,发生脱位3例,脱位率1.7%;髋臼唇外展角>50°~60°75例,发生脱位8例,脱位率10.7%;髋臼唇外展角>60°19例,发生脱位2例,脱位率10.5%,脱位率组间差异有显著性(χ~2=9.082,P=0.028,R=-0.074)。结论为了减少髋关节置换术后的脱位率,髋臼外展角的角度多应该选择在≥40°~50°,尽可能避免在其他角度。
