This cadaveric study aimed to determine if acetabular retroversion demonstrates predictable changes with age that could inform understanding of factors that may contribute to the pathophysiology of femoroacetabular impingement. Two-hundred forty pelves were divided into young and old groups. Version was measured at the cranial (5mm below superior rim), central (transverse of acetabulum), and caudal (5mm above inferior rim) locations. The data showed a significant difference between young (10±10°) and old (13±9°) cranial version (P=.02). Cranial retroversion increases with age and may reflect a developmental component in the etiology of the focal rim impingement lesion or ossification of the damaged labrum. Global acetabular retroversion does not appear to change with age and may reflect a congenital etiology.
这项尸体研究旨在确定髋臼后倾是否随年龄呈现可预测的变化，这有助于理解可能导致股骨髋臼撞击症病理生理学的因素。240例骨盆被分为年轻组和老年组。在髋臼上缘下方5毫米处的颅侧、髋臼中部（髋臼横断处）和髋臼下缘上方5毫米处的尾侧测量髋臼后倾角度。数据显示，年轻组（10±10°）和老年组（13±9°）的颅侧髋臼后倾角度存在显著差异（P = 0.02）。颅侧髋臼后倾随年龄增加，可能反映了局灶性髋臼边缘撞击病变病因中的发育因素或受损盂唇的骨化。整体髋臼后倾似乎不随年龄变化，可能反映先天性病因。
