The purpose of this article is to determine normative values for the length of the acetabular rim and detect differences between gender, age, ethnicity, height and leg length. Six measurements were taken on the acetabular rim of 143 cadaveric skeleton specimens (286 acetabula) using a coordinate-measuring device: circumferential (excluding acetabular notch), anterior inferior iliac spine (AIIS)-anterior, AIIS-posterior, 12-3 o'clock, 12-9 o'clock and 11-5 o'clock. Museum specimen height data and leg length data from a previous study were recorded for 109 of 143 specimens. Intraclass correlation coefficients were calculated. Student -tests compared mean values. Multiple regression analysis was used to determine the relationship between acetabular rim length and gender, age, ethnicity, height and leg length. The average acetabular rim length in males for circumferential, AIIS-anterior, AIIS-posterior, 12-3, 12-9 and 11-5 o'clock were 15.8, 4.2, 11.7, 4.9, 4.7 and 9.5 cm, respectively; and for females: 13.7, 3.7, 10.0, 4.3, 4.1 and 8.3 cm, respectively. Intraclass correlation coefficients were 0.953, 0.930, 0.958, 0.857, 0.913 and 0.951, respectively, for each measurement. All six measurements were significantly larger for males ( < 0.001). Multiple regression analysis demonstrated a significant relationship between gender and rim length for all six measurements ( < 0.001) and between height and leg length and acetabular rim length for five of the six measurements exclusive of AIIS-anterior ( < 0.001). No significant trends between age or ethnicity and rim length were found. Average acetabular rim lengths were established. The acetabular rim is significantly longer in males and correlates with height and leg length. Age and ethnicity do not appear to be significant predictors of acetabular rim length. Normative values for acetabular rim lengths may assist in hip preservation surgery.
本文旨在确定髋臼缘长度的标准值，并检测性别、年龄、种族、身高和腿长之间的差异。使用坐标测量设备对143个尸体骨骼标本（286个髋臼）的髋臼缘进行了六项测量：圆周（不包括髋臼切迹）、髂前下棘（AIIS）-前方、AIIS-后方、12点-3点、12点-9点和11点-5点。记录了143个标本中109个标本来自先前研究的博物馆标本身高数据和腿长数据。计算了组内相关系数。采用学生t检验比较均值。多元回归分析用于确定髋臼缘长度与性别、年龄、种族、身高和腿长之间的关系。男性圆周、AIIS-前方、AIIS-后方、12点-3点、12点-9点和11点-5点的髋臼缘平均长度分别为15.8、4.2、11.7、4.9、4.7和9.5厘米；女性分别为13.7、3.7、10.0、4.3、4.1和8.3厘米。每项测量的组内相关系数分别为0.953、0.930、0.958、0.857、0.913和0.951。所有六项测量男性均显著更大（<0.001）。多元回归分析表明，所有六项测量中性别与髋臼缘长度之间存在显著关系（<0.001），六项测量中的五项（不包括AIIS-前方）身高和腿长与髋臼缘长度之间存在显著关系（<0.001）。未发现年龄或种族与髋臼缘长度之间的显著趋势。确定了髋臼缘平均长度。髋臼缘在男性中明显更长，且与身高和腿长相关。年龄和种族似乎不是髋臼缘长度的重要预测因素。髋臼缘长度的标准值可能有助于保髋手术。
