S62.132 Displaced fracture of capitate [os magnum] bone, left wrist

Name of the Condition

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

Summary

This condition involves a break in the capitate bone, one of the central carpal bones in the left 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 unstable or severely displaced fractures.
• 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 with proper care, but some may experience long-term stiffness or reduced function. Follow-up appointments monitor healing and adjust treatment as needed.

Complications

• Nonunion or delayed healing of the fracture.
• Arthritis in the wrist joint due to misalignment.
• Nerve or tendon damage from the injury or surgery.
• Chronic pain or reduced mobility.

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.
• Strengthen wrist muscles through regular exercise.

When to Seek Professional Help

Seek immediate medical attention for severe pain, visible deformity, inability to move the wrist, or signs of infection (e.g., redness, fever). Follow up with a healthcare provider if symptoms worsen or do not improve with initial treatment.

Tips for Medical Coders

Document the specific location (left wrist) and displacement status clearly. Include details on fracture type (e.g., closed, open) and treatment provided to support accurate coding. Ensure alignment with clinical notes and imaging reports for specificity.
