S62.253 Displaced fracture of neck of first metacarpal bone, unspecified hand

Name of the Condition

• Displaced fracture of neck of first metacarpal bone, unspecified 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.
• Reduction: Manual or surgical realignment of displaced bone fragments if necessary.
• Pain management: Medications to reduce discomfort and inflammation.
• Rehabilitation: Physical therapy to restore strength and mobility after healing.

Prognosis and Follow-Up

Most fractures heal within 6–8 weeks with proper immobilization and care. Follow-up appointments monitor healing progress and adjust treatment as needed. Full recovery of function depends on the severity of the fracture and adherence to rehabilitation.

Complications

• Nonunion or malunion 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.
• Maintain bone health through adequate calcium and vitamin D intake.
• Avoid falls by using assistive devices if balance is impaired.

When to Seek Professional Help

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

Tips for Medical Coders

Document the specific hand (right/left) if known; use "unspecified" only when the hand is not documented. Include details on displacement and fracture type to support code assignment. Ensure clinical documentation aligns with the ICD-10-CM guidelines for fractures.
