M71.042 Abscess of bursa, left hand

Name of the Condition

• Abscess of bursa, left hand

Summary

An abscess of the bursa, left hand is a localized collection of pus within a bursa in the left hand, a small fluid-filled sac that reduces friction between tissues. This condition typically causes pain, swelling, and warmth at the affected site. The left hand-specific designation indicates the abscess is localized to the bursa in the left hand region.

Causes

Abscesses of the left hand bursa usually result from bacterial infection, often introduced through direct trauma, skin breakdown, or spread from adjacent tissues. Staphylococcus aureus is a common causative organism. Non-infectious causes, such as foreign body reaction or sterile inflammation, are less frequent.

Risk Factors

• Recent injury or surgery near the left hand bursa
• Skin infections or open wounds in the left hand area
• Immunocompromised states (e.g., diabetes, HIV)
• Chronic inflammatory conditions (e.g., rheumatoid arthritis)
• Repetitive motion or pressure on the left hand bursa

Symptoms

• Localized pain, tenderness, or throbbing in the left hand
• Swelling, redness, or warmth over the bursa
• Limited range of motion in the left hand or wrist
• Possible fever or systemic signs if infection spreads
• Pus drainage if the abscess ruptures

Diagnosis

Diagnosis involves a physical examination to assess bursal swelling, warmth, and tenderness. Imaging (e.g., ultrasound) may confirm fluid collection. Aspiration of the bursa may be performed to identify the causative organism and guide treatment.

Treatment Options

Treatment typically includes antibiotic therapy for bacterial infections, often targeting Staphylococcus aureus. Drainage of the abscess may be necessary if it does not resolve with antibiotics alone. Rest, elevation, and pain management are also recommended. Surgical intervention may be required for large or persistent abscesses.

Prognosis and Follow-Up

With appropriate treatment, most abscesses of the left hand bursa resolve without complications. Follow-up care ensures the infection is cleared and functional recovery is monitored. Recurrence is possible if underlying risk factors are not addressed.

Complications

Untreated or inadequately treated abscesses may lead to spread of infection, tissue damage, or chronic bursitis. Rarely, systemic infection (sepsis) can occur if the abscess ruptures or spreads.

Lifestyle & Prevention

• Avoid repetitive hand motions that strain the bursa
• Practice good hand hygiene to prevent infections
• Protect the left hand from trauma or injury
• Manage chronic conditions (e.g., diabetes) to reduce infection risk
• Seek prompt care for hand injuries or infections

When to Seek Professional Help

Consult a healthcare provider if you experience persistent pain, swelling, or warmth in the left hand, especially with fever or pus drainage. Early intervention can prevent complications.

Tips for Medical Coders

Document the specific location (left hand) and confirm the abscess is localized to the bursa. Ensure clinical documentation supports the diagnosis and any associated procedures, such as drainage or imaging.
