S62.142 Displaced fracture of body of hamate [unciform] bone, left wrist

Name of the Condition

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

Summary

This condition involves a break in the body of the hamate bone, one of the small carpal bones in the left 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. 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 left 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 to reduce pain and inflammation.
• Surgical intervention: May be required for severe displacement or if fragments affect surrounding nerves or tendons.
• Rehabilitation: Physical therapy to restore strength and range of motion after healing.

Prognosis and Follow-Up

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

Complications

• Delayed union or nonunion of the fracture.
• Nerve or tendon damage due to displaced fragments.
• Chronic pain or arthritis in the wrist.
• Reduced grip strength or range of motion.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Maintain bone health through diet and exercise.
• Avoid falls by using assistive devices if needed.
• Warm up and stretch before physical activities.

When to Seek Professional Help

Seek immediate care for severe pain, visible deformity, numbness, or inability to move the wrist or fingers. Persistent pain or swelling after initial treatment also warrants evaluation.

Tips for Medical Coders

Document the side (left wrist) and displacement status clearly. Include details on fracture type (e.g., closed) and encounter stage (e.g., initial, subsequent) if applicable. Ensure clinical notes support the diagnosis and any associated complications.
