M61.111
Myositis ossificans progressiva, right shoulder
Clinical Classification Guidelines
Medical Intelligence & Overview
Myositis ossificans progressiva (MOP) affecting the right shoulder is a rare condition characterized by abnormal bone formation within the soft tissues, such as muscles, around the shoulder. The condition often results in pain, swelling, and restricted movement, significantly impacting daily activities. While myositis ossificans typically develops after trauma or injury, this progressive form involves ongoing ossification, leading to increasingly limited shoulder mobility over time.
Causes & Symptoms
Clinical Causes: Prior trauma or injury to the shoulder, such as fractures, sprains, or surgeries Repeated trauma or stress to the shoulder area Genetic factors, although rare, can predispose individuals to abnormal ossification Underlying inflammatory conditions that may promote abnormal bone growth Certain medical treatments or procedures that involve the shoulder region
Key Symptoms: Gradual stiffness and decreased range of motion in the right shoulder Swelling or palpable firm mass around the shoulder muscles Persistent or increasing pain, especially during shoulder movement Development of hard, bony lumps within the soft tissues Muscle weakness due to restricted movement In some cases, skin may appear taut or stretched over the ossified tissue
Diagnostic & Treatment
Diagnosis Path: X-rays to visualize abnormal bone formation in soft tissues Magnetic Resonance Imaging (MRI) for detailed views of soft tissues and to assess the extent of ossification Bone scans to detect active bone growth areas Review of patient history, including any prior trauma or surgeries to the shoulder Biopsy may be performed in uncertain cases to confirm diagnosis
Treatment Protocols: Rest and activity modification to prevent worsening of ossification Physical therapy aimed at maintaining as much shoulder flexibility as possible without exacerbating the condition Medications such as non-steroidal anti-inflammatory drugs (NSAIDs) to reduce pain and inflammation Surgical intervention to remove ossified tissue may be considered if there is significant functional impairment or persistent pain, though recurrence risk exists In some cases, preventive strategies or medications that inhibit abnormal bone growth are explored
