M70.10

Clinical Causes: Repeated or prolonged mechanical pressure or friction on the hand, such as frequent gripping or gripping tools Injury or trauma to the hand, including falls or blows Overuse from repetitive activities like typing, manual labor, or sports Infection, especially if bacteria enter the bursae through a wound or puncture Underlying inflammatory conditions, such as rheumatoid arthritis or gout Age-related degeneration leading to increased susceptibility Certain occupations that involve repetitive hand movements

Key Symptoms: Localized swelling around the affected bursae in the hand Tenderness or sensitivity to touch Pain, especially when moving or applying pressure to the hand Limited range of motion or stiffness in the fingers or wrist Warmth and redness over the inflamed area Possible fluid accumulation, visible as a bump or lump

Diagnosis Path: Diagnosis typically involves a clinical examination where a healthcare provider assesses the hand's appearance, tenderness, and range of motion. Imaging tests, such as X-rays, can help rule out other issues like fractures, while ultrasound or MRI imaging can confirm inflammation of the bursae. In some cases, fluid from the bursae may be sampled for laboratory analysis to detect infection or other causes. Medical history detailing recent injuries or repetitive activities is also considered in diagnosis.

Treatment Protocols: Management of bursitis of the hand aims to alleviate pain, reduce inflammation, and restore movement. Typical treatment options include: - Rest and activity modification to avoid aggravating movements - Application of ice packs to reduce swelling and pain - Use of nonsteroidal anti-inflammatory drugs (NSAIDs) to reduce inflammation and discomfort - Physical therapy exercises to improve mobility and strengthen surrounding muscles - Aspiration of excess fluid from the bursae if swelling is significant - Corticosteroid injections to decrease inflammation in persistent cases - Addressing underlying causes, such as treating infections or managing chronic inflammatory conditions In cases where conservative treatments do not lead to improvement, or if the bursitis is caused by infection, surgical intervention may be considered. Prevention strategies include ergonomic adjustments, proper techniques during repetitive tasks, and protective gear during activities that pose injury risks.
