M61.11
Myositis ossificans progressiva, shoulder
Clinical Classification Guidelines
Medical Intelligence & Overview
Myositis ossificans progressiva of the shoulder, classified under ICD-10 code M61.11, is a rare and complex condition characterized by abnormal bone formation within muscle tissues surrounding the shoulder joint. This condition can lead to progressive stiffness, limited movement, and discomfort in the affected shoulder, significantly impacting daily activities and quality of life. It is distinguished from other forms of myositis and ossification by its progressive nature and specific localization.
Causes & Symptoms
Clinical Causes: Previous trauma or injury to the shoulder muscles or tissues Repeated or severe muscle injuries Genetic predisposition to abnormal bone growth In rare cases, it may be associated with certain genetic syndromes Surgical procedures involving the shoulder area Prolonged immobilization or lack of movement post-injury
Key Symptoms: Gradual development of hard, lump-like masses within the shoulder muscles Progressive pain and tenderness in the affected area Restricted range of motion, particularly with shoulder movements like lifting or rotating Swelling and inflammation around the shoulder Visible or palpable calcified deposits in the muscle tissues Possible skin changes over time, such as firmness or tightness
Diagnostic & Treatment
Diagnosis Path: Physical examination to assess swelling, masses, and range of motion limitations X-ray imaging to identify calcified or ossified areas within the muscle tissues Ultrasound to evaluate soft tissue involvement Computed tomography (CT) scans for detailed visualization of bone formation Magnetic resonance imaging (MRI) to assess soft tissue details and rule out other conditions Biopsy in some cases to confirm the presence of heterotopic bone tissue
Treatment Protocols: Rest and activity modification to prevent exacerbation Physical therapy tailored to maintain as much shoulder flexibility as possible Medications such as non-steroidal anti-inflammatory drugs (NSAIDs) to reduce inflammation and pain In some cases, corticosteroid injections may be used for symptom relief Surgical removal of ossified tissue may be considered if the mass causes significant restriction or discomfort, although recurrence is possible Emerging therapies exploring the management of abnormal bone growth are under investigation
