S62.144 Nondisplaced fracture of body of hamate [unciform] bone, right wrist

Name of the Condition

• Nondisplaced fracture of body of hamate [unciform] bone, right wrist

Summary

This condition refers to a break or crack in the body of the hamate bone, one of the small carpal bones in the right wrist, without 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 nondisplaced fractures generally involving less structural disruption compared to displaced variants.

Causes

Typically 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 in the ulnar side of the right 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 promote healing.
• Pain management: Medications or therapies to reduce discomfort and inflammation.
• Rehabilitation: Physical therapy to restore strength and range of motion once healing progresses.

Prognosis and Follow-Up

Most nondisplaced fractures heal well with proper immobilization and follow-up care. Recovery time varies but typically ranges from 6 to 8 weeks. Regular follow-up appointments may be needed to monitor healing and adjust treatment as necessary.

Complications

• Delayed union or nonunion of the fracture.
• Chronic pain or stiffness in the wrist.
• Nerve or tendon irritation due to swelling or bone fragments (rare in nondisplaced cases).

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Maintain bone health through proper nutrition and exercise.
• Avoid falls by using assistive devices if balance is a concern.

When to Seek Professional Help

Seek immediate medical attention if pain worsens, swelling increases, or there is loss of function. Persistent symptoms after initial treatment may also require further evaluation.

Tips for Medical Coders

Document the specific location (right wrist) and nondisplaced nature of the fracture. Ensure clinical notes support the absence of fragment displacement to justify this code. Verify that the injury is isolated to the body of the hamate bone and not associated with other carpal fractures or complications.
