M21.151
Varus deformity, not elsewhere classified, right hip
Clinical Classification Guidelines
Medical Intelligence & Overview
Varus deformity of the right hip, classified under ICD-10 code M21.151, is a condition where the thigh bone (femur) angles inward at the hip joint. This abnormal positioning results in the knee pointing outward when the legs are straightened, causing a bow-legged appearance. The deformity is not classified elsewhere, meaning it is a specific type of hip misalignment that can affect mobility and overall well-being if left unmanaged. Recognizing this condition is important to explore appropriate management options that can improve function and reduce discomfort.
Causes & Symptoms
Clinical Causes: Congenital conditions present at birth, such as developmental dysplasia of the hip, which can cause abnormal growth and angulation. Trauma or injuries to the hip or femur that disrupt normal bone development or alignment. Infections that damage the growth plates or the bone structure during childhood. Nutritional deficiencies affecting bone growth, such as rickets caused by vitamin D deficiency. Degenerative joint diseases or osteoarthritis that alter joint structure over time. Genetic factors influencing bone development and strength.
Key Symptoms: Visible bow-legged appearance, especially when standing or walking. Discomfort or pain in the hip, thigh, or knee regions. Altered gait or walking pattern, often with difficulty maintaining balance. Reduced range of motion in the affected hip. Muscle fatigue or weakness around the hip joint. Potential development of joint unevenness leading to early joint wear.
Diagnostic & Treatment
Diagnosis Path: Diagnosis of varus deformity involves a comprehensive clinical assessment, including history taking and physical examination. The healthcare provider will observe the alignment of the legs and hips, assess mobility, and check for pain or deformity. Imaging studies are crucial for confirmation and include:
Treatment Protocols: Management strategies depend on the severity of the deformity and the underlying cause. Approaches may include:
