S62.348 Nondisplaced fracture of base of other metacarpal bone

Name of the Condition

• Nondisplaced fracture of base of other metacarpal bone

Summary

A nondisplaced fracture of the base of another metacarpal bone involves a small break or crack in the base of one of the hand bones (excluding the thumb), where the bone fragments remain in their normal alignment. This type of injury typically results from trauma or impact to the hand.

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 tenderness at the base of the affected metacarpal bone.
• Swelling and bruising around the injured area.
• Difficulty or pain when moving the corresponding finger.

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 splint or cast: To keep the bones in place while 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 nondisplaced fractures heal well with proper immobilization and care, often within 4–6 weeks. Follow-up appointments monitor healing progress and may include repeat imaging. Full recovery of strength and function is typical, but activity restrictions may be necessary during healing.

Complications

• Delayed healing or nonunion if immobilization is inadequate.
• Stiffness or reduced range of motion in the affected finger.
• Chronic pain in rare cases.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Maintain bone health through adequate calcium and vitamin D intake.
• Avoid repetitive hand stress or improper technique in manual tasks.

When to Seek Professional Help

Seek care if pain worsens, swelling increases, or movement becomes impossible. Immediate evaluation is needed for signs of infection, severe deformity, or loss of sensation.

Tips for Medical Coders

Document the specific metacarpal bone (e.g., third, fourth, or fifth) and confirm the fracture is nondisplaced. Include details on trauma mechanism, imaging results, and treatment to support code specificity. Ensure alignment with clinical findings and avoid assumptions about bone involvement.
