摘　　要：目的 :通过对髋臼后壁厚度的解剖学测量及定量分析,探讨髋臼后上壁的形态特点及临床意义,为髋臼骨折的临床治疗提供理论参考。方法:选取15具经甲醛浸泡处理的成年防腐尸体骨盆标本(男8具,女7具),清除多余软组织后对髋臼整个后壁采用角度分区法,分别测量不同层面不同分割点的后壁厚度,对测量结果进行统计学分析。结果:距臼缘5 mm处测量的髋臼后上壁平均厚度波动于(6.47±0.61)mm至(7.43±0.71)mm之间,髋臼后下壁平均厚度波动于(5.62±0.51)mm至(6.33±0.61)mm之间,臼顶平均厚度波动于(7.71±0.74)mm至(8.27±0.99)mm之间,距臼缘5 mm处髋臼后上壁厚度与髋臼后下壁厚度比较差异无统计学意义(P>0.05),但臼顶厚度较髋臼后上壁增厚较显著(P<0.05);距臼缘10 mm处测量的髋臼后上壁厚度波动于(8.81±0.67)mm到(13.35±0.89)mm之间,髋臼后下壁厚度波动于(7.02±0.63)mm至(7.66±0.69)mm之间,臼顶平均厚度波动于(14.46±0.97)mm至(17.05±1.35)mm之间,距臼缘10 mm处髋臼后上壁厚度较髋臼后下壁增厚较显著(P<0.05),臼顶厚度较髋臼后上壁增厚显著(P<0.01);距臼缘15 mm处测量的髋臼后上壁厚度波动于(12.08±0.78)mm至(19.84±1.03)mm之间,髋臼后下壁厚度波动于(10.17±0.76)mm至(11.12±0.77)mm之间,臼顶平均厚度波动于(23.23±1.12)mm至(26.01±1.53)mm之间,距臼缘15 mm处髋臼后上壁厚度较髋臼后下壁增厚显著(P<0.01),臼顶厚度较髋臼后上壁增厚显著(P<0.01)。结论:整个髋臼后缘厚度从髋臼后下壁→髋臼后上壁→臼顶部呈现逐渐增厚趋势,这种趋势随着测量点距臼缘距离的不断增加而愈加明显。髋臼后上壁除了传统意义上维持"头臼对应"稳定性功能外,还可能参与髋臼部分负重。Objective：To explore morphological character and clinical significance of superior-posterior acetabular wall by anatomically measuring and quantitatively analyzing thickness of posterior acetabular wall,then provide a theoretical reference for clinical treatment of acetabular fracture.Methods：Fifteen adult formalin-preserved cadaveric pelvises （8 males and 7 females） were used for this investigation.Excess soft tissue was removed and the whole acetabular posterior walls were marked with ＂angle＂ sector method and the thickness was measured with caliper in different levels of the different split points.The measurement results were validated and analyzed statistically.Results：At 5 mm away from acetabular rim,the average thickness of superior-posterior acetablar wall fluctuated between （6.47±0.61） mm and （7.43±0.71） mm; the average thickness of inferior-posterior acetabuluar wall fluctuated between （5.62±0.51） mm and （6.33±0.61） mm ;the average thickness of acetabular roof fluctuated between （7.71±0.74） mm and （8.27±0.99） mm.There was no statistical difference between average thickness of superior-posterior wall of acetabulum and inferior-posterior wall of acetabulum （P＞0.05）,but the average thickness of acetabular roof was significantly larger than superior-posterior acetabular wall （P＜0.05）.At 10 mm away from the acetabular rim,the average thickness of superior-posterior acetabular wall fluctuated between （8.81±0.67） mm and （13.35±0.89）mm;the average thickness of inferior-posterior acetabular wall fluctuated between （7.02±0.63） mm and （7.66±0.69） mm; the average thickness of acetabular roof fluctuated between （14.46t0.97） mm and （17.05± 1.35） mm.Comparatively,the average thickness of superior-posterior acetabular wall was significantly larger than inferior-posterior wall of acetabulum （P＜0.05）,and the average thickness of acetabular roof was significantly larger than superior-posterior acetabular wall （P＜0.01）.At 15 mm
