S62.14 Fracture of body of hamate [unciform] bone

Name of the Condition

• Fracture of body of hamate [unciform] bone

Summary

This condition refers to a break or crack in the body of the hamate bone, one of the small carpal bones in the wrist. 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 or without displacement of bone fragments.

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 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 area and promote healing.
• Pain management: Medications like NSAIDs to reduce pain and inflammation.
• Physical therapy: To restore strength and range of motion after immobilization.
• Surgical intervention: May be required for displaced fractures or those involving joint surfaces.

Prognosis and Follow-Up

Most fractures of the hamate bone heal with proper immobilization and care, though recovery time varies based on severity. Follow-up imaging may be needed to confirm healing. Complications like nonunion or arthritis are possible but not common with appropriate treatment.

Complications

• Nonunion or delayed healing of the fracture.
• Post-traumatic arthritis in the wrist joint.
• Nerve or tendon irritation due to bone fragment displacement.
• Reduced grip strength or persistent pain.

Lifestyle & Prevention

• Use protective gear during high-risk activities (e.g., sports).
• Maintain bone health through adequate calcium and vitamin D intake.
• Avoid falls by using assistive devices if balance is impaired.

When to Seek Professional Help

Seek immediate medical attention if you experience severe wrist pain, swelling, or deformity after an injury, or if symptoms worsen despite rest.

Tips for Medical Coders

Document the specific location (body of hamate) and any associated details, such as displacement or open fracture, to support accurate coding. Ensure clinical documentation aligns with the fracture's characteristics for proper code assignment.
