M71.01

Clinical Causes: Bacterial infections introduced through a cut, scrape, or puncture wound near the shoulder Spread of infection from nearby tissues or skin Repeated shoulder trauma or overuse, leading to inflammation and increased susceptibility to infection Complication of underlying bursitis with bacterial invasion Infections resulting from invasive medical procedures involving the shoulder

Key Symptoms: Severe pain in the shoulder region, often worsening with movement Swelling and tenderness over the affected bursa Warmth and redness around the shoulder area Limited range of motion in the shoulder joint Fever and chills in some cases, indicating systemic infection Possible palpable fluctuant mass (a soft, fluid-filled swelling)

Diagnosis Path: Diagnosis typically involves a combination of clinical examination and imaging studies. The healthcare provider will assess symptoms and look for signs of inflammation or swelling. Imaging techniques such as ultrasound or MRI can visualize the abscess within the bursa. In some cases, a needle aspiration of the bursa may be performed to obtain a sample of the pus for microbiological analysis, which helps identify the causative bacteria and guide antibiotic therapy.

Treatment Protocols: {'antibiotics': 'Targeted antibiotic therapy based on microbiological findings to eliminate the bacterial infection', 'drainage': 'Procedural drainage of the abscess to remove pus and reduce pressure, often performed via needle aspiration or surgical incision', 'rest and immobilization': 'Limiting shoulder movement to promote healing and prevent further injury', 'pain management': 'Use of analgesics to control pain', 'follow-up care': 'Monitoring for signs of recurrence or complications and physical therapy to restore shoulder function after infection resolution'}
