M91.11

Clinical Causes: Unknown exact cause, but thought to involve temporary interruption of blood flow to the femoral head Genetic factors may play a role in susceptibility Environmental factors such as trauma or injury to the hip region Hormonal or metabolic abnormalities might contribute, although they are not well defined

Key Symptoms: Limping or gait abnormalities Pain or discomfort in the hip, groin, thigh, or knee Limited range of motion in the affected hip Muscle weakness around the hip Stiffness, especially after periods of rest or sleep Affected leg may appear shorter over time as the disease progresses

Diagnosis Path: Diagnosis involves a combination of clinical examination and imaging studies. Healthcare providers typically perform a physical assessment to evaluate hip mobility, pain, and muscle strength. Imaging tests such as X-rays are essential to visualize changes in the femoral head, including deformities, fragmentation, or signs of necrosis. In some cases, MRI may be used for a more detailed assessment of blood supply and early disease detection.

Treatment Protocols: Management of juvenile osteochondrosis aims to relieve symptoms, ensure proper hip joint development, and prevent long-term deformities. Treatment options include: - **Rest and activity modification**, to reduce stress on the hip - **Physical therapy**, to maintain joint mobility and muscle strength - **Pain management** with medications as prescribed by a healthcare professional - **Use of braces or orthotic devices**, to support hip alignment - **Surgical interventions**, in cases where deformities are significant or there is persistent pain, including procedures to reshape or stabilize the hip joint - **Regular monitoring** with follow-up imaging to assess disease progression and treatment effectiveness
