S62.231 Other displaced fracture of base of first metacarpal bone, right hand

Name of the Condition

• Other displaced fracture of base of first metacarpal bone, right hand

Summary

This condition involves a displaced fracture at the base of the first metacarpal bone, which connects the thumb to the wrist. The fracture results in misalignment of the bone fragments, potentially affecting joint stability and function. 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 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 and evaluate the degree of displacement and 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, involving realignment and fixation of the bone fragments.

Prognosis and Follow-Up

Recovery depends on the severity of the fracture and treatment. Immobilization and rehabilitation typically restore function, but some cases may result in long-term stiffness or reduced mobility. Follow-up imaging and physical therapy are often recommended to monitor healing and regain strength.

Complications

• Persistent pain or stiffness.
• Reduced range of motion in the thumb.
• Arthritis or joint instability if the fracture affects the joint surface.
• Nerve or tendon damage in severe cases.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Maintain bone health through proper nutrition and exercise.
• Avoid repetitive stress on the thumb and hand.

When to Seek Professional Help

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

Tips for Medical Coders

Document the specific location (base of the first metacarpal bone) and laterality (right hand) to ensure accurate coding. Note the displacement status and any associated injuries, as these details impact code assignment.
