M61.38

Clinical Causes: Severe burn injuries leading to tissue damage and abnormal healing processes Prolonged immobilization or inactivity of the affected region post-burn Repeated or unresolved inflammatory responses in the burned tissue Presence of heterotopic ossification, where bone forms outside the normal skeletal system, often in muscles near burned areas Previous surgeries or interventions that may disturb normal tissue repair mechanisms Underlying conditions that predispose to abnormal calcium or bone deposits, such as metabolic disorders

Key Symptoms: Muscle stiffness around the affected area Pain, often persistent or worsening over time Swelling or limited range of motion in the limb or area affected Visible or palpable hard lumps within the muscle tissue Decreased mobility in joints near the burned region In some cases, skin over the area may feel tense or firm

Diagnosis Path: X-ray imaging to identify abnormal calcium deposits or bone formation in muscles Computed tomography (CT) scans for detailed visualization of the extent and location of ossification Magnetic resonance imaging (MRI) to evaluate soft tissue involvement and rule out other causes of muscle stiffness Bone scans, in some cases, to assess active ossification processes Biopsy, if necessary, to confirm the nature of the calcifications or ossified tissue

Treatment Protocols: Physical therapy exercises designed to maintain range of motion and prevent stiffness Pain management strategies, including medications or other modalities Surgical intervention to remove heterotopic ossification or calcified tissue in severe cases Preventive measures such as early rehabilitation and mobilization post-burn Monitoring and controlling inflammation to reduce ongoing tissue damage Consideration of medications that inhibit abnormal bone growth, though evidence varies
