Slipped capital femoral epiphysis Early mechanical damage to the acetabular cartilage by a prominent femoral metaphysis
On the basis of intraoperative observa-tions 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 dam-age.As a result of an impingement between the metaphy-sis and the superomedial acetabular rim,the labrum re-vealed erosions,scars or tears.Further jamming of the metaphysis into the joint damaged the adjacent acetabu-lar 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 find-ings suggest that arthrosis in SCFE can be triggered by early mechanical damage of the acetabular cartilage.
