تعريف
Legg-Calve-Perthes disease (LCPD) is a rare hip disease. It affects children 2-12 years old. LCPD is a disorder of the top of the leg bone. The disorder interrupts blood flow to the hip. The loss of flow impairs bone growth and causes deformity. Over time, the bone breaks and reforms causing the child to limp. LCPD most often occurs in just one hip, with only about 10% of cases involving both sides.
أسباب
The cause of LCPD is unknown. Infection, trauma, and inflammatory processes are possible causes.
