髋臼盂唇撕裂是髋部疼痛的一个有据可查的来源，但由于对骨形态和盂唇撕裂之间的关系知之甚少，因此损伤机制存在争议。我们比较了有和没有盂唇异常的髋关节，以确定形态异常的相对发生率。研究组由在开放清创术或髋臼周围截骨术时经关节镜检查或关节切开术证实盂唇撕裂的患者组成。我们将受影响的髋关节与对侧未受影响的髋关节进行比较，以确定髋关节发育不良和撞击的迹象。我们观察到中心边缘角、髋臼深度宽度指数、髋臼抬高指数、股骨头突出、外侧和上半脱位、夏普角、峰至边缘距离和髋臼后倾角的差异。亚组分析中也出现了类似的差异。有症状的盂唇撕裂与髋部形态异常相关，如X线发育不良和撞击的测量结果所反映的。这种关系发生在髋关节发育不良患者和股骨头未明显裸露的患者中。我们的研究结果表明异常的髋部形态可能是盂唇撕裂的危险因素。
A torn acetabular labrum is a well-documented source of hip pain, but the mechanism of injury is debated because the relationship between the bone morphology and labral tears is poorly understood. We compared hips with and without labral abnormalities to determine the relative incidence of morphologic abnormalities. The study group consisted of patients with a labral tear confirmed by arthroscopy or arthrotomy at the time of open debridement or periacetabular osteotomy. We compared the affected hip with the contralateral, unaffected hip to ascertain signs of hip dysplasia and impingement. We observed differences in the center edge angle, acetabular depth to width index, acetabular index of elevation, femoral head extrusion, lateral and superior subluxation, Sharp's angle, peak to edge distance, and acetabular retroversion. Similar differences occurred in the subgroup analyses. Symptomatic labral tears correlated with abnormal hip morphology as reflected by radiographic measurements of dysplasia and impingement. This relationship occurred in patients with hip dysplasia and patients without obvious femoral head uncovering. Our findings suggest abnormal hip morphology may be a risk factor for labral tears.
