M62.11

Clinical Causes: Degenerative muscle changes due to age or chronic wear and tear Overuse or repetitive strain from activities involving shoulder movements Muscle weakness or atrophy from conditions such as neurological disorders Poor blood supply to the muscle tissue, leading to weakened muscle fibers Underlying systemic illnesses affecting muscle health, such as autoimmune diseases Use of corticosteroid medications that can weaken muscle tissue Sudden muscle contractions during activity, even without external trauma

Key Symptoms: Sudden pain in the shoulder region, often described as sharp or burning Swelling or bruising around the shoulder Weakness in shoulder movements or difficulty lifting the arm A feeling of muscle rupture or tearing within the shoulder Limited range of motion due to pain or muscle integrity loss Tenderness upon touching the affected area

Diagnosis Path: Review of the patient's symptoms and any relevant medical history Physical assessment to evaluate the strength, tenderness, and range of motion of the shoulder Ultrasound imaging to visualize muscle tissues and detect tears or ruptures Magnetic resonance imaging (MRI) for detailed imaging of soft tissue injuries and confirming muscle rupture Additional tests to rule out other causes of shoulder pain, such as rotator cuff injuries or joint issues

Treatment Protocols: Rest and activity modification to prevent further injury Application of ice packs to reduce inflammation and swelling Use of pain relievers or anti-inflammatory medications as recommended by a healthcare provider Physical therapy focusing on gentle stretching and strengthening exercises In some cases, immobilization with a shoulder brace or sling to support healing In severe cases or if conservative treatments fail, surgical intervention may be necessary to repair the damaged muscle
