S62.232 Other displaced fracture of base of first metacarpal bone, left hand

Name of the Condition

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

Summary

This condition involves a displaced fracture at the base of the first metacarpal bone, which connects the thumb to the wrist in the left hand. 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 left 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.
• Reduction: Manual or surgical realignment of displaced bone fragments if necessary.
• Pain management: Medications to alleviate discomfort.
• Rehabilitation: Physical therapy to restore strength and mobility after healing.

Prognosis and Follow-Up

Most fractures heal with proper treatment, but recovery time depends on the severity of displacement and adherence to immobilization or rehabilitation. Follow-up imaging may be needed to ensure proper healing. Long-term outcomes are generally good, though some residual stiffness or weakness may occur.

Complications

• Nonunion or delayed healing of the fracture.
• Arthritis or joint stiffness due to misalignment or trauma.
• Nerve or tendon damage in severe cases.
• Chronic pain or reduced function if treatment is inadequate.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Maintain bone health through proper nutrition and exercise.
• Avoid falls by modifying environments (e.g., removing tripping hazards).
• Strengthen hand and wrist muscles to improve resilience.

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). Persistent symptoms after initial treatment also warrant evaluation.

Tips for Medical Coders

Document the specific location (left hand), displacement status, and any associated injuries. Ensure the fracture is confirmed via imaging and note the encounter type (e.g., initial, subsequent) for accurate coding.
