Coxa plana
Clinical Classification Guidelines
Inclusion Terms
- Hip deformity due to previous juvenile osteochondrosis
Medical Intelligence & Overview
Coxa plana, also known as avascular necrosis of the femoral head, is a condition that affects the hip joint, primarily seen in children and adolescents. It is characterized by the damage or death of bone tissue in the femoral head due to decreased blood flow, leading to deformity and impaired hip function. This condition often results from juvenile osteochondrosis, a disorder involving the disruption of blood supply to the growing bones. Recognized under ICD-10 code M91.2, coxa plana can cause significant discomfort and mobility issues if not diagnosed and managed appropriately.
Causes & Symptoms
Clinical Causes: Juvenile osteochondrosis leading to compromised blood supply to the femoral head Previous trauma or injury to the hip region Genetic predisposition affecting bone development Overuse or repetitive stress on the hip joint during growth spurts Underlying vascular abnormalities impairing blood flow
Key Symptoms: Hip pain, especially during activity or bearing weight Limping or an abnormal gait Reduced range of motion in the hip joint Tenderness around the hip area Muscle weakness or atrophy in the thigh Stiffness in the hip, particularly after periods of inactivity
Diagnostic & Treatment
Diagnosis Path: Diagnosing coxa plana involves a combination of physical examinations and imaging studies. The physician will evaluate hip movement, pain levels, and the overall gait. Imaging tests typically include:
Treatment Protocols: Management of coxa plana aims to relieve symptoms, restore hip function, and prevent progression. Treatment strategies include:
