S62.343 Nondisplaced fracture of base of third metacarpal bone, left hand

Name of the Condition

• Nondisplaced fracture of base of third metacarpal bone, left hand

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.

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 of the metacarpal base heal well with proper immobilization and follow-up care. Recovery time typically ranges from 4 to 6 weeks, depending on the individual's healing rate. Regular follow-up appointments are recommended to monitor progress and adjust treatment as needed.

Complications

• Delayed healing or nonunion if the fracture is not properly immobilized.
• Stiffness or reduced range of motion in the affected finger.
• Chronic pain or arthritis in the joint if the fracture affects cartilage or ligaments.

Lifestyle & Prevention

• Use protective gear, such as gloves, during high-risk activities.
• Maintain bone health through a balanced diet rich in calcium and vitamin D.
• Avoid repetitive motions that strain the hand and wrist.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, swelling, or deformity after a hand injury. Contact a healthcare provider if symptoms worsen or do not improve with initial treatment.

Tips for Medical Coders

Document the specific location (base of the third metacarpal bone) and laterality (left hand) to ensure accurate coding. Include details about the fracture's alignment (nondisplaced) and any associated trauma or mechanism of injury to support the diagnosis.
