S62.511 Displaced fracture of proximal phalanx of right thumb

Name of the Condition

• Displaced fracture of proximal phalanx of right thumb

Summary

This injury involves a fracture in the proximal phalanx, the bone segment closest to the hand, of the right 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: Using a splint, cast, or brace to stabilize the bone and allow healing.
• Closed reduction: A procedure performed by a healthcare professional to realign bones without surgery.
• Surgery: May be necessary if the fracture is significantly displaced or unstable, involving internal fixation with pins, screws, or plates.

Prognosis and Follow-Up

Most fractures heal within 6–8 weeks with proper immobilization and care. Follow-up appointments monitor healing progress and may include range-of-motion exercises to restore function. Full recovery depends on the severity of the fracture and adherence to treatment.

Complications

• Malunion or nonunion of the bone.
• Stiffness or reduced range of motion in the thumb.
• Chronic pain or arthritis in the affected joint.
• Nerve or tendon damage in severe cases.

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.

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, pus, fever) after an injury.

Tips for Medical Coders

Document the specific location (proximal phalanx of right thumb), displacement status, and any associated injuries. Ensure clinical notes support the diagnosis and treatment provided to justify code assignment.
