S62.133 Displaced fracture of capitate [os magnum] bone, unspecified wrist

Name of the Condition

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

Summary

This condition involves a break in the capitate bone, one of the central carpal bones in the 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.
• Closed reduction: Manual realignment of displaced bone fragments without surgery.
• Surgical intervention: Internal fixation with pins, screws, or plates for severe displacement or instability.
• Rehabilitation: Physical therapy to restore strength and range of motion after healing.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, alignment after treatment, and adherence to rehabilitation. Most patients recover full function with proper care, but some may experience residual stiffness or weakness. Follow-up appointments monitor healing and adjust treatment as needed.

Complications

• Nonunion or malunion of the fracture.
• Chronic pain or arthritis in the wrist.
• Nerve or tendon damage from the injury or surgery.
• Reduced grip strength or mobility.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Maintain bone health through diet and exercise.
• Avoid falls by improving balance and home safety.
• Seek prompt treatment for wrist injuries to prevent complications.

When to Seek Professional Help

Consult a healthcare provider if you experience severe wrist pain, swelling, or deformity after an injury. Immediate care is needed for open fractures, loss of sensation, or inability to move the hand.

Tips for Medical Coders

Document the displacement and unspecified wrist location clearly. Ensure clinical notes specify the fracture type and absence of laterality to support accurate coding. Verify that trauma history and imaging results align with the diagnosis for proper code assignment.
