S62.31 Displaced fracture of base of other metacarpal bone

Name of the Condition

• Displaced fracture of base of other metacarpal bone

Summary

A displaced fracture of the base of another metacarpal bone involves a break in the proximal (base) portion of one of the hand bones, excluding the thumb, where the bone fragments are misaligned. This injury typically results from trauma or impact to the hand, leading to a fracture that disrupts the normal alignment of the bone.

Causes

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

Risk Factors

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

Symptoms

• Pain and swelling in the hand.
• Tenderness or bruising around the affected area.
• Difficulty moving the fingers or hand.
• Possible 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.

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 fractures heal well with appropriate treatment, though recovery time depends on the severity of the injury and adherence to rehabilitation. Follow-up appointments are typically scheduled to monitor healing and adjust treatment as needed.

Complications

• Nonunion or delayed healing of the fracture.
• Malunion, where the bone heals in an abnormal position.
• Stiffness or reduced range of motion in the hand.
• Nerve or tendon damage in severe cases.

Lifestyle & Prevention

• Use protective gear during sports or high-risk activities.
• Maintain bone health through a balanced diet and regular exercise.
• Avoid repetitive hand movements that may increase stress on the metacarpals.

When to Seek Professional Help

Seek medical attention if you experience severe pain, swelling, or deformity after a hand injury, or if symptoms worsen despite initial care.

Tips for Medical Coders

Document the specific metacarpal bone involved (excluding the thumb) and confirm displacement to support accurate coding. Include details about the fracture's location (base) and alignment to ensure compliance with ICD-10-CM guidelines.
