S62.343A Nondisplaced fracture of base of third metacarpal bone, left hand, initial encounter for closed fracture

Name of the Condition

• Nondisplaced fracture of base of third metacarpal bone, left hand, initial encounter for closed fracture

Summary

A nondisplaced fracture of the base of the third metacarpal bone in the left hand involves a small break or crack in the bone that connects to the middle finger, where the bone fragments remain in proper alignment. This type of injury typically results from trauma or direct impact to the hand and is classified as a closed fracture (no open wound) during the initial encounter.

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 third metacarpal bone.
• Swelling and bruising around the affected area.
• Difficulty or pain when moving the middle 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 rest. Follow-up appointments are typically scheduled to monitor healing and adjust treatment as needed. Full recovery may take several weeks, depending on the individual's age and overall health.

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-impact activities.
• Maintain bone health through a balanced diet and regular exercise.
• Avoid repetitive hand motions that may increase stress on the metacarpal bones.

When to Seek Professional Help

Seek immediate medical attention if there is severe pain, swelling, or inability to move the finger, or if the hand appears deformed.

Tips for Medical Coders

Document the specific location (base of third metacarpal bone, left hand), fracture type (nondisplaced), encounter type (initial), and whether the fracture is closed. Ensure clinical notes support the diagnosis and treatment provided.
