M91: Juvenile osteochondrosis of hip and pelvis

Juvenile osteochondrosis of the hip and pelvis refers to a group of conditions that mainly affect growing children, particularly during periods of rapid growth. Common amongst active children or adolescents, these conditions are characterized by the temporary disruption of blood supply to specific areas of the hip and pelvis, leading to the death of bone cells. The ensuing process of regeneration or repair can result in localized areas of bone weakness, causing pain and potentially leading to deformity. Symptoms often include limping, pain in the hip, thigh or knee, and restricted movement. If the condition is in the hip, it may also lead to a condition known as a 'slipped capital femoral epiphysis'. Overall, juvenile osteochondrosis is associated with significant consequences for the musculoskeletal system, potentially resulting in long-term mobility problems if not managed precisely.
