M71.842

Clinical Causes: Repeated or sustained pressure on the left hand during various activities, causing bursae irritation. Trauma or injury to the left hand that impacts bursae integrity. Overuse or repetitive motions involving the left hand, such as gripping or gripping devices. Infections that may spread to bursae, leading to bursitis. Increased anatomic pressure due to swelling or other underlying conditions. Degenerative changes associated with aging or osteoarthritis affecting hand joints. Certain systemic inflammatory conditions, such as rheumatoid arthritis, influencing bursae health.

Key Symptoms: Localized swelling or lump on the back or palm of the left hand Tenderness or discomfort in specific areas of the left hand Pain that worsens with movement or pressure Limited range of motion or stiffness in the fingers or wrist Redness or warmth over the affected area A feeling of heaviness or weakness in the hand Possible signs of infection, such as fever or pus (if bursitis is infectious)

Diagnosis Path: Imaging tests such as ultrasound or MRI to visualize bursae and assess inflammation or fluid accumulation Aspiration of joint fluid or bursal fluid for laboratory analysis, especially when infection is suspected Blood tests to identify systemic inflammatory or infectious causes X-rays to rule out other underlying joint or bone pathology

Treatment Protocols: Rest and immobilization of the affected hand to prevent further irritation Application of ice packs to decrease swelling and pain Nonsteroidal anti-inflammatory drugs (NSAIDs) to reduce inflammation and discomfort Physical therapy exercises to maintain mobility and strengthen the hand muscles Aspiration of excess fluid from the bursae if swelling is significant or causes discomfort Corticosteroid injections to moderate inflammation in persistent cases Treating any underlying systemic or local infection with appropriate antibiotics Surgical intervention, such as bursectomy (removal of inflamed bursae), in severe or refractory cases
