S62.241 Displaced fracture of shaft of first metacarpal bone, right hand

Name of the Condition

• Displaced fracture of shaft of first metacarpal bone, right hand

Summary

This condition involves a break in the shaft (midportion) of the first metacarpal bone, which connects 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 injuries.

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 alignment of bone fragments.

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 to realign and fix the bone fragments, often with pins, screws, or plates.
• Rehabilitation: Physical therapy to restore strength and range of motion after healing.

Prognosis and Follow-Up

Most fractures heal within 6–8 weeks with proper treatment. Follow-up imaging may be needed to ensure proper healing. Full recovery of function depends on the severity of the fracture and adherence to treatment plans. Regular monitoring by a healthcare provider is recommended during the healing process.

Complications

• Malunion (improper healing of the bone).
• Nonunion (failure of the bone to heal).
• Arthritis or stiffness in the thumb joint.
• Nerve or tendon damage in severe cases.
• Chronic pain or reduced grip strength.

Lifestyle & Prevention

• Use protective gear during high-risk activities (e.g., sports).
• Maintain bone health through a balanced diet and regular exercise.
• Avoid falls by using assistive devices if needed, especially in older adults.
• Practice proper hand positioning during activities to reduce 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). Prompt evaluation is important to prevent complications and ensure proper treatment.

Tips for Medical Coders

Document the specific location (shaft of first metacarpal), displacement, and laterality (right hand) to accurately assign this code. Ensure clinical notes support the diagnosis and any associated treatments, as these details may impact coding and reimbursement.
