S62.241A Displaced fracture of shaft of first metacarpal bone, right hand, initial encounter for closed fracture

Name of the Condition

• Displaced fracture of shaft of first metacarpal bone, right hand, initial encounter for closed fracture

Summary

This condition involves a break in the shaft (middle portion) of the first metacarpal bone, which connects the thumb to the wrist, with displacement of the bone fragments. The fracture is closed (skin intact) and occurs during the initial encounter for treatment. Displacement means the bone fragments are not aligned properly, 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 whether the fracture is closed.

Treatment Options

• Immobilization: Using a cast, splint, or brace to stabilize the area and promote healing.
• Pain management: Medications to reduce discomfort and inflammation.
• Reduction: Manual or surgical realignment of displaced bone fragments to restore proper alignment.
• Surgery: Internal fixation (e.g., pins, plates) if the fracture is unstable or fails to heal with non-surgical methods.

Prognosis and Follow-Up

Most fractures heal within 6–8 weeks with proper immobilization and care. Follow-up imaging may be needed to confirm healing. Physical therapy may be recommended to restore strength and range of motion. Long-term outcomes depend on the severity of the fracture and adherence to treatment.

Complications

• Nonunion or malunion (fracture fails to heal or heals incorrectly).
• Arthritis or stiffness in the thumb joint.
• Nerve or tendon damage from the injury or treatment.
• Chronic pain or reduced function.

Lifestyle & Prevention

• Use protective gear during high-risk activities (e.g., sports, manual labor).
• 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 you experience severe pain, visible deformity, inability to move the thumb, or signs of infection (e.g., redness, fever). Follow up with a healthcare provider if symptoms worsen or do not improve with initial treatment.

Tips for Medical Coders

Document the fracture location (shaft of first metacarpal), laterality (right hand), displacement status, and encounter type (initial for closed fracture). Ensure clinical notes specify the fracture is closed and displaced to support accurate coding. Include details on treatment provided (e.g., reduction, immobilization) to align with coding guidelines.
