S62.252 Displaced fracture of neck of first metacarpal bone, left hand

Name of the Condition

• Displaced fracture of neck of first metacarpal bone, left hand

Summary

This condition involves a break in the neck of the first metacarpal bone (the bone connecting the thumb to the wrist) with displacement of the bone fragments. Displacement means the broken pieces are no longer aligned properly. The severity and treatment depend on the extent of displacement and associated joint involvement.

Causes

Typically caused by direct trauma, such as a fall onto an outstretched hand, a forceful blow to the thumb, or a crushing injury. High-impact activities or accidents may also lead to this type of fracture.

Risk Factors

• Participation in contact sports or activities with a high risk of falls.
• Osteoporosis or weakened bone structure, especially in older adults.
• Previous hand or thumb injuries that may have compromised bone integrity.

Symptoms

• Pain, swelling, and tenderness at the base of the thumb or hand.
• Bruising or discoloration around the injury site.
• Limited range of motion or difficulty moving the thumb.
• Visible deformity in severe cases.

Diagnosis

Physical examination to assess pain, swelling, and mobility. Imaging tests, such as X-rays, CT scans, or MRIs, to confirm the fracture, evaluate displacement, and check for joint involvement.

Treatment Options

• Immobilization: Using a cast, splint, or brace to stabilize the fracture and allow healing.
• Closed reduction: Manual realignment of the bone fragments without surgery, if appropriate.
• Surgical intervention: Internal fixation (e.g., pins, screws) for severe displacement or unstable fractures.
• Pain management: Medications to reduce discomfort during recovery.
• Rehabilitation: Physical therapy to restore strength and mobility once healing progresses.

Prognosis and Follow-Up

Most fractures heal within 6–8 weeks with proper immobilization and care. Follow-up imaging may be used to monitor alignment and healing. Full recovery of function depends on the severity of the fracture and adherence to treatment. Long-term outcomes are generally favorable with appropriate management.

Complications

• Malunion or nonunion of the fracture.
• Stiffness or reduced range of motion in the thumb.
• Arthritis in the thumb joint over time.
• Nerve or tendon damage in severe cases.

Lifestyle & Prevention

• Use protective gear during high-risk activities (e.g., sports).
• Maintain bone health through adequate calcium and vitamin D intake.
• Avoid falls by using assistive devices if balance is impaired.
• Practice proper hand positioning during activities to reduce injury risk.

When to Seek Professional Help

Seek immediate medical attention if there is severe pain, visible deformity, inability to move the thumb, or signs of infection (e.g., redness, fever). Prompt evaluation is important to prevent complications and ensure proper healing.

Tips for Medical Coders

Document the specific location (left hand), displacement status, and any associated details (e.g., open/closed, initial encounter) to accurately reflect the condition. Ensure clinical documentation supports the diagnosis and aligns with ICD-10-CM coding guidelines for fractures.
