S62.135 Nondisplaced fracture of capitate [os magnum] bone, left wrist

Name of the Condition

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

Summary

This condition refers to a break or crack in the capitate bone, one of the central carpal bones in the left wrist, without displacement of 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 nondisplaced fractures generally requiring less invasive management to promote healing.

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 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 its extent and alignment.

Treatment Options

• Immobilization: Using a cast, splint, or brace to stabilize the area and promote healing.
• Pain management: Medications to reduce discomfort and inflammation.
• Physical therapy: Exercises to restore strength and mobility once healing progresses.
• Surgical intervention: Rarely required for nondisplaced fractures, but may be considered if instability or other complications arise.

Prognosis and Follow-Up

Most nondisplaced fractures of the capitate bone heal well with proper immobilization and follow-up care. Recovery time varies but typically ranges from 6 to 12 weeks. Regular follow-up appointments with a healthcare provider are important to monitor healing and adjust treatment as needed.

Complications

• Delayed union or nonunion of the fracture.
• Arthritis in the wrist joint over time.
• Nerve or tendon damage in severe cases.
• Reduced wrist function if not properly managed.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Maintain bone health through a balanced diet and regular exercise.
• Avoid falls by using assistive devices if needed, especially in older adults.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, swelling, or deformity after a wrist injury. Contact a healthcare provider if symptoms worsen or do not improve with initial treatment.

Tips for Medical Coders

Document the specific location (left wrist) and the nondisplaced nature of the fracture. Ensure clinical notes support the absence of fragment displacement to justify the use of this code. Verify that the injury is isolated to the capitate bone and not associated with other carpal fractures or complications.
