通过对13例（14髋）青少年股骨头骨骺滑脱（SCFE）患者的术中观察，我们发现当股骨干骺端与骨骺齐平或超过骨骺时，会造成盂唇和软骨损伤。由于干骺端和髋臼内侧上缘之间的撞击，盂唇出现糜烂、疤痕或撕裂。干骺端进一步卡在关节内损伤了邻近的髋臼软骨，从部分到全层软骨损失不等。所有患者的股骨头软骨完整，无缺血性坏死。我们的研究结果表明，关节病在SCFE可以引发早期机械损伤的髋臼软骨。
On the basis of intraoperative observations in 13 consecutive adolescents (14 hips) with slipped capital femoral epiphysis (SCFE), we found that when the anterior femoral metaphysis was level with or extended past the epiphysis, it caused labrum and cartilage damage. As a result of an impingement between the metaphysis and the superomedial acetabular rim, the labrum revealed erosions, scars or tears. Further jamming of the metaphysis into the joint damaged the adjacent acetabular cartilage, varying from a partial- to a full-thickness cartilage loss. In all patients, the femoral head cartilage was intact; no avascular necrosis was present. Our findings suggest that arthrosis in SCFE can be triggered by early mechanical damage of the acetabular cartilage.
