S62.513 Displaced fracture of proximal phalanx of unspecified thumb

Name of the Condition

• Displaced fracture of proximal phalanx of unspecified thumb

Summary

This condition involves a fracture in the proximal phalanx, the bone segment closest to the hand, of the thumb. The fracture is displaced, meaning the bone segments have shifted out of their normal alignment. The severity and treatment depend on the degree of displacement and associated soft tissue damage.

Causes

Typically caused by direct trauma or impact to the thumb, such as a fall onto an outstretched hand, blunt force trauma, or a crush injury. Common scenarios include accidents, sports injuries, or workplace incidents involving the hand.

Risk Factors

• Participation in contact sports or activities with a high risk of hand injuries.
• Osteoporosis or other conditions that weaken bone density.
• Previous thumb or hand injuries.
• Age-related bone fragility, particularly in older adults.

Symptoms

• Pain, swelling, and bruising localized to the thumb.
• Limited range of motion or difficulty moving the thumb.
• Visible deformity or abnormal thumb alignment.
• Tenderness to touch at the injury site.

Diagnosis

Physical examination to assess pain, swelling, and mobility. Imaging tests, such as X-rays, to confirm the fracture and evaluate displacement or fragmentation. Additional imaging (e.g., CT or MRI) may be used for complex cases.

Treatment Options

• Immobilization: Use of a splint or cast to stabilize the thumb and allow healing.
• Reduction: Manual or surgical realignment of displaced bone fragments.
• Surgery: Internal fixation with pins, screws, or plates for severe displacement or unstable fractures.
• 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 appointments monitor healing progress and adjust treatment as needed. Full recovery depends on fracture severity, treatment adherence, and rehabilitation.

Complications

• Stiffness or reduced range of motion in the thumb.
• Chronic pain or arthritis in the affected joint.
• Nonunion or malunion of the fracture.
• Nerve or tendon damage from the injury or treatment.

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 repetitive or forceful thumb movements that may increase injury risk.
• Practice fall prevention strategies to reduce trauma from falls.

When to Seek Professional Help

Seek immediate medical attention for severe pain, visible deformity, inability to move the thumb, or signs of infection (e.g., redness, pus). Prompt evaluation is critical for proper diagnosis and treatment.

Tips for Medical Coders

Document the fracture as displaced and specify the thumb as unspecified. Include details on trauma mechanism, imaging results, and treatment provided. Ensure alignment with clinical findings to support code accuracy.
