M92.51
Juvenile osteochondrosis of proximal tibia
Clinical Classification Guidelines
Inclusion Terms
- Blount disease
- Tibia vara
Medical Intelligence & Overview
Juvenile osteochondrosis of the proximal tibia, commonly known as Blount disease, is a growth disorder that affects the areas of bone just below the knee. It leads to abnormal development and angulation of the tibia (shinbone), often resulting in bowing of the leg. This condition typically occurs in children and adolescents and can impact mobility and leg alignment if not diagnosed and managed appropriately.
Causes & Symptoms
Clinical Causes: Excessive mechanical stress on the tibia during growth periods Obesity, which increases pressure and strain on the growth plate Genetic predisposition or family history of the condition Early walking or weight-bearing activities in predisposed children Nutritional factors affecting bone growth
Key Symptoms: Progressive bowing or angulation of the lower leg, especially below the knee Visible deformity where the leg appears bowed outward Pain or tenderness around the affected area Unequal leg length or gait abnormalities Reduced ability to walk or perform physical activities comfortably
Diagnostic & Treatment
Diagnosis Path: Diagnosis typically involves a physical examination and imaging studies. The physician will assess leg alignment and measure deformity angles. X-rays are essential for visualizing growth plate abnormalities, bone development, and the degree of bowing. In some cases, MRI or other imaging techniques may be used to evaluate soft tissues and cartilage. Early diagnosis is important to determine the severity and guide treatment planning.
Treatment Protocols: Observation for mild cases to monitor progression Bracing or orthotic devices to guide bone growth and reduce deformity Surgical intervention such as guided growth surgery (epiphysiodesis) or osteotomy to correct deformity Physical therapy to strengthen muscles and improve gait Addressing contributing factors such as obesity through nutritional and lifestyle counseling
