S62.344 Nondisplaced fracture of base of fourth metacarpal bone, right hand

Name of the Condition

• Nondisplaced fracture of base of fourth metacarpal bone, right hand

Summary

A nondisplaced fracture of the base of the fourth metacarpal bone in the right hand involves a small break or crack in the bone that connects to the ring finger, where the bone fragments remain in proper alignment. This type of injury typically results from trauma or direct impact to the hand.

Causes

Direct trauma, such as a fall onto the hand or a blow to the area, is the primary cause. Sports-related injuries, accidents, or repetitive stress may also lead to this fracture.

Risk Factors

• Participation in activities with a risk of hand trauma, such as contact sports or manual labor.
• Reduced bone density, which can increase susceptibility to fractures.
• Inadequate hand protection during high-risk activities.

Symptoms

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

Diagnosis

Physical examination by a healthcare provider to assess tenderness, swelling, or deformity. Imaging tests, such as X-rays, are used to confirm the fracture and verify that the bone fragments are properly aligned.

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, typically within 4–6 weeks. Follow-up appointments monitor healing progress and may include repeat imaging. Full recovery of strength and function is common, but some residual stiffness or mild discomfort may persist.

Complications

• Delayed healing or nonunion if the fracture is not properly immobilized.
• Stiffness or reduced range of motion in the affected finger.
• Chronic pain in rare cases.

Lifestyle & Prevention

• Use protective gear during high-risk activities, such as sports or manual labor.
• Maintain bone health through adequate calcium and vitamin D intake.
• Avoid repetitive hand stress or overuse to reduce fracture risk.

When to Seek Professional Help

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

Tips for Medical Coders

Document the specific location (base of the fourth metacarpal bone) and laterality (right hand) to ensure accurate coding. Include details about the fracture type (nondisplaced) and any associated injuries or treatments for complete coding specificity.
