S62.251 Displaced fracture of neck of first metacarpal bone, right hand

Name of the Condition

• Displaced fracture of neck of first metacarpal bone, right 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 area and promote healing.
• Pain management: Medications to reduce discomfort and inflammation.
• Surgical intervention: May be required for severe displacement or instability to realign and fix the bone fragments.

Prognosis and Follow-Up

Most fractures heal with proper treatment, but recovery time depends on the severity and treatment approach. Follow-up appointments monitor healing and may include physical therapy to restore strength and mobility. Full recovery can take several weeks to months.

Complications

• Stiffness or reduced range of motion in the thumb.
• Chronic pain or arthritis in the affected joint.
• Nerve or tendon damage in severe cases.
• Nonunion or malunion of the fracture if not properly treated.

Lifestyle & Prevention

• Use protective gear during high-risk activities (e.g., sports).
• Maintain bone health through a balanced diet and regular exercise.
• Avoid repetitive or forceful thumb movements that may increase injury risk.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, visible deformity, inability to move the thumb, or signs of infection (e.g., redness, fever) after an injury.

Tips for Medical Coders

Document the specific location (neck of first metacarpal bone) and laterality (right hand) to ensure accurate coding. Note any displacement, as this affects code assignment. Include details about trauma mechanism, imaging results, and treatment provided for comprehensive coding.
