S62.141 Displaced fracture of body of hamate [unciform] bone, right wrist

Name of the Condition

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

Summary

This condition involves 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. 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 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 area and promote healing.
• Pain management: Medications like NSAIDs to reduce pain and inflammation.
• Physical therapy: To restore strength and range of motion after healing.
• Surgical intervention: May be required for severe displacement or associated nerve/ligament damage.

Prognosis and Follow-Up

Most fractures heal with proper immobilization and care, but recovery time depends on fracture severity and treatment. Follow-up imaging may be needed to assess healing. Complications like arthritis or nerve compression can occur if fragments are not properly aligned.

Complications

• Chronic pain or stiffness in the wrist.
• Arthritis due to joint damage.
• Nerve compression (e.g., ulnar nerve) from displaced fragments.
• Reduced grip strength or range of motion.

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

Tips for Medical Coders

Document the specific bone (hamate), displacement status, and laterality (right wrist) to support accurate coding. Include details on trauma mechanism, imaging findings, and treatment to clarify clinical context. Ensure documentation aligns with the ICD-10-CM guidelines for fracture coding.
