S62.317A Displaced fracture of base of fifth metacarpal bone, left hand, initial encounter for closed fracture

Name of the Condition

• Displaced fracture of base of fifth metacarpal bone, left hand, initial encounter for closed fracture

Summary

A displaced fracture of the base of the fifth metacarpal bone in the left hand is a break in the proximal (base) portion of the fifth metacarpal, where the bone fragments are misaligned. This injury typically results from trauma or direct impact to the hand, leading to pain, swelling, and potential functional impairment. The fracture is closed, meaning the skin is intact, and this is the initial encounter for treatment.

Causes

Direct trauma, such as a fall or blow to the hand. Sports-related injuries or accidents involving the hand. Repetitive stress or overuse in certain activities.

Risk Factors

• Participation in contact sports or high-impact activities.
• Reduced bone density or osteoporosis.
• Occupational hazards involving manual labor or repetitive hand movements.

Symptoms

• Pain and swelling in the left hand.
• Tenderness or bruising around the affected area.
• Difficulty moving the fingers or gripping objects.
• Possible visible deformity or misalignment.

Diagnosis

Physical examination by a healthcare provider to assess tenderness, swelling, or deformity. Imaging tests, such as X-rays, to confirm the fracture and evaluate its extent and displacement.

Treatment Options

• Immobilization with a cast or splint to promote healing.
• Pain management using over-the-counter or prescription medications.
• Physical therapy to restore mobility and strength.
• Surgery may be required for severe or displaced fractures to realign the bone.

Prognosis and Follow-Up

Most displaced fractures of the metacarpal base heal well with appropriate treatment, though recovery time varies. Follow-up care typically includes monitoring for proper healing and assessing functional recovery. Physical therapy may be recommended to restore full range of motion and strength.

Complications

• Nonunion or delayed healing of the fracture.
• Malunion, where the bone heals in a misaligned position.
• Stiffness or reduced mobility in the hand or fingers.
• Chronic pain or discomfort.

Lifestyle & Prevention

• Use protective gear during sports or high-risk activities.
• Maintain bone health through adequate calcium and vitamin D intake.
• Avoid repetitive stress on the hand when possible.
• Practice proper ergonomics during manual tasks.

When to Seek Professional Help

Seek immediate medical attention if there is severe pain, visible deformity, inability to move the hand or fingers, or signs of infection (e.g., redness, warmth, or pus).

Tips for Medical Coders

Document the specific location (base of fifth metacarpal, left hand), displacement status, and encounter type (initial for closed fracture) to ensure accurate coding. Include details of the injury mechanism, clinical findings, and treatment provided to support the diagnosis.
