S62.131 Displaced fracture of capitate [os magnum] bone, right wrist

Name of the Condition

• Displaced fracture of capitate [os magnum] bone, right wrist

Summary

This condition involves a break in the capitate bone, one of the central carpal bones in the right wrist, with displacement of the bone fragments. The capitate is the largest carpal bone and plays a key role in wrist stability and movement. Fractures in this area typically result from trauma and may vary in severity, with displaced fragments requiring specific management to restore alignment and function.

Causes

Usually caused by direct trauma to the wrist, such as a fall onto an outstretched hand, a blow to the wrist, or a high-impact injury. Crushing or twisting forces 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 central wrist area.
• 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 the extent of displacement 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 to realign and fix the bone fragments.

Prognosis and Follow-Up

Recovery depends on the severity of the fracture and treatment. Immobilization and proper care typically allow for healing within 6–8 weeks. Follow-up imaging may be needed to ensure proper alignment. Long-term outcomes are generally good with appropriate treatment, though some stiffness or reduced mobility may persist.

Complications

• Nonunion or malunion of the fracture.
• Chronic pain or arthritis in the wrist.
• Nerve or tendon damage from displaced fragments.
• Reduced grip strength or range of motion.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Maintain bone health through adequate calcium and vitamin D intake.
• Avoid falls by using assistive devices if balance is impaired.
• Perform wrist-strengthening exercises to support joint stability.

When to Seek Professional Help

Seek immediate medical attention if you experience severe wrist pain, swelling, deformity, or inability to move the hand after an injury. Persistent pain, numbness, or tingling may indicate nerve involvement and require evaluation.

Tips for Medical Coders

Document the specific bone (capitate) and side (right wrist) affected, as well as the displacement status. Ensure clinical notes confirm the fracture type and any associated injuries to support accurate coding.
