S62.252A Displaced fracture of neck of first metacarpal bone, left hand, initial encounter for closed fracture

Name of the Condition

• Displaced fracture of neck of first metacarpal bone, left hand, initial encounter for closed fracture

Summary

This condition involves a displaced fracture of the neck of the first metacarpal bone, which connects the thumb to the wrist. The fracture is closed, meaning the skin is intact, and it is the initial encounter for treatment. Displacement indicates that the bone fragments are misaligned, which may affect healing and function.

Causes

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

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 in the thumb or base of the 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 and evaluate its extent, including displacement and 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 displacement and adherence to rehabilitation.

Complications

• Malunion or nonunion of the fracture.
• Chronic pain or stiffness in the thumb or hand.
• Nerve or tendon damage in severe cases.
• Arthritis in the thumb joint over time.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Maintain bone health through diet and exercise.
• Avoid falls by modifying home environments (e.g., removing tripping hazards).

When to Seek Professional Help

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

Tips for Medical Coders

Document the fracture as displaced, specify the left hand, and confirm it is a closed fracture with no skin penetration. Note the initial encounter for treatment to ensure accurate coding. Include details on imaging or reduction procedures if performed.
