M61.151
Myositis ossificans progressiva, right thigh
Clinical Classification Guidelines
Medical Intelligence & Overview
Myositis ossificans progressiva (MOP) is a rare, chronic condition characterized by abnormal bone formation within soft tissues, specifically muscles, tendons, and other connective structures. When this condition affects the right thigh, it can lead to significant limitations in movement and muscle function. MOP should not be confused with more common muscle injuries; it involves true bone growth in soft tissues that can impair mobility and cause discomfort over time.
Causes & Symptoms
Clinical Causes: Trauma or injury to the thigh muscles, such as fractures, bruises, or surgical procedures Genetic predisposition, although rare, can lead to progressive ossification Repeated injuries or persistent inflammation in the thigh muscles
Key Symptoms: Hard, lump-like masses within the thigh muscles that grow over time Pain and tenderness, especially during activity or movement Reduced range of motion in the hip and knee joints Swelling or inflammation in the affected area Muscle weakness or stiffness that worsens with time Difficulty walking or performing daily activities due to decreased mobility
Diagnostic & Treatment
Diagnosis Path: Medical history focusing on recent or past thigh injuries Physical examination to assess muscle tightness and masses Imaging tests such as X-rays, which typically reveal abnormal bone formation within soft tissue MRI scans to evaluate the extent of soft tissue involvement and differentiate from other conditions Biopsy may be performed in atypical cases to confirm diagnosis and exclude malignancy
Treatment Protocols: Rest and activity modification to prevent aggravation of bone growth Physical therapy to maintain joint flexibility and muscle strength Medications such as non-steroidal anti-inflammatory drugs (NSAIDs) to reduce inflammation Surgical intervention may be considered in severe cases to remove ossified tissue, especially if it impairs function Monitoring for progression through regular imaging studies
