S62.143 Displaced fracture of body of hamate [unciform] bone, unspecified wrist

Name of the Condition

• Displaced fracture of body of hamate [unciform] bone, unspecified wrist

Summary

This condition refers to a break in the body of the hamate bone, one of the small carpal bones in the wrist, with displacement of bone fragments. The hamate is located on the ulnar (pinky) side of the wrist and contributes to wrist stability and grip function. Fractures in this area typically result from trauma and may vary in severity, with displaced fragments potentially affecting surrounding structures.

Causes

Usually caused by direct trauma to the wrist, such as a fall onto an outstretched hand, a blow to the wrist, or a crushing injury. High-impact activities or accidents may also lead to fractures in this specific bone.

Risk Factors

• Participation in contact sports or activities with a high risk of falls.
• Osteoporosis or weakened bone structure, especially in older adults.
• Previous wrist injuries or fractures.

Symptoms

• Pain, swelling, and tenderness on the ulnar side of the wrist.
• Bruising or discoloration around the injury site.
• Limited range of motion or difficulty moving the hand or fingers.
• Visible deformity in severe cases.

Diagnosis

Physical examination to assess pain, swelling, and wrist mobility. Imaging tests, such as X-rays, CT scans, or MRIs, to confirm the fracture and evaluate its extent and alignment.

Treatment Options

• Immobilization: Using a cast, splint, or brace to stabilize the wrist and allow healing.
• Surgical intervention: May be required for severe displacement or if fragments affect surrounding structures.
• Pain management: Medications or therapies to reduce discomfort during recovery.
• Rehabilitation: Physical therapy to restore strength and mobility after healing.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture and treatment. Most fractures heal with proper care, but recovery may take several weeks to months. Follow-up appointments monitor healing and adjust treatment as needed. Complications like arthritis or nerve damage are possible but not always present.

Complications

• Delayed healing or nonunion of the fracture.
• Arthritis in the wrist due to joint damage.
• Nerve or tendon injury from displaced bone fragments.
• Chronic pain or reduced wrist function.

Lifestyle & Prevention

• Use protective gear during high-risk activities like sports.
• Maintain bone health through proper nutrition and exercise.
• Avoid falls by using assistive devices if balance is impaired.
• Seek prompt treatment for wrist injuries to prevent complications.

When to Seek Professional Help

Consult a healthcare provider if you experience severe wrist pain, swelling, or inability to move the hand after an injury. Immediate care is needed for visible deformity, numbness, or signs of infection.

Tips for Medical Coders

Document the specific wrist side (right/left) if known, as this affects code assignment. For unspecified wrist, use the provided code. Ensure clinical documentation supports displacement and fracture location to justify the code.
