Report of Break-out Session: Management of Sequelae of Legg-Calvé-Perthes Disease

Excerpt

Sequelae of Legg-Calvé-Perthes disease (LCPD) are an important cause of hip pain in the young adult population and are associated with the development of premature osteoarthritis in approximately 50% of those affected [5, 11]. The extent of epiphyseal involvement, age at disease onset, and modes of childhood treatment affect the shape of the hip at skeletal maturity [12]. The resultant deformity varies substantially and is impossible to characterize uniformly. The spectrum of hip deformity includes a high trochanter, short femoral neck, misshapen femoral head, hypertrophied labrum, femoral and acetabular chondral lesions, torsional deformity of the femur and acetabulum, and secondary acetabular deformity [6, 9]. These anatomic abnormalities can lead to varying coexisting combinations of intra- and extraarticular femoroacetabular impingement, joint incongruity, hip instability, articular and labral damage, and secondary osteoarthritis. As such, assessment of pathoanatomy and mechanical dysfunction in symptomatic patients is individualized. …
