M12.252

Villonodular synovitis (pigmented), left hip

Clinical Classification Guidelines

Medical Intelligence & Overview

Villonodular synovitis is a joint condition characterized by the abnormal growth of the synovial membrane, the soft tissue that lines joints. When this condition occurs specifically in the left hip, it can lead to pain, swelling, and limited mobility. This form can be pigmented, meaning it involves pigmented, villous, or nodular tissue growths. Recognized under ICD-10 code M12.252, it is a relatively rare condition that primarily affects young and middle-aged adults. Proper understanding of its causes, symptoms, and treatment options is vital for managing its impact on daily life.

Causes & Symptoms

Clinical Causes: The exact cause of villonodular synovitis remains unclear, though it is believed to stem from abnormal cell growth within the synovial membrane. Potential factors include inflammation responses, previous joint injuries, or genetic predispositions. Some studies suggest it might have a neoplastic component, meaning it could behave somewhat like a benign tumor. Environmental factors, such as repetitive joint stress or trauma, may also contribute to its development.

Key Symptoms: Persistent joint pain, especially during movement or activity. Swelling and tenderness around the affected hip joint. Reduced range of motion, resulting in stiffness or difficulty moving the hip. A sense of catching or locking in the joint, particularly with certain movements. Occasional warmth or redness over the joint area due to inflammation. In advanced cases, swelling may be visible and palpable.

Diagnostic & Treatment

Diagnosis Path: Diagnosis typically involves a combination of clinical examination and imaging studies. Medical professionals may recommend the following:

Treatment Protocols: Treating villonodular synovitis aims to remove abnormal tissue, alleviate symptoms, and prevent recurrence. Common approaches include:
