S62.164 Nondisplaced fracture of pisiform, right wrist

Name of the Condition

• Nondisplaced fracture of pisiform, right wrist

Summary

This condition refers to a break in the pisiform bone of the right wrist where the bone fragments remain in their normal anatomical position. The pisiform is a small, pea-shaped carpal bone located on the palmar (palm) side of the wrist, embedded within the flexor carpi ulnaris tendon. Nondisplaced fractures typically result from trauma and may vary in severity, with the bone maintaining its structural alignment.

Causes

Typically caused by direct trauma to the wrist, such as a fall onto an outstretched hand, a blow to the palmar side of 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 palmar 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 wrist and allow healing.
• Pain management: Over-the-counter or prescription medications to reduce discomfort.
• Physical therapy: Exercises to restore strength and range of motion once healing progresses.
• Surgical intervention: Rarely required for nondisplaced fractures, but may be considered if conservative treatment fails.

Prognosis and Follow-Up

Most nondisplaced fractures heal well with proper immobilization and rest. Recovery typically takes 4–6 weeks, with follow-up appointments to monitor healing and adjust treatment as needed. Full function often returns, though some residual stiffness or weakness may persist.

Complications

• Delayed healing or nonunion if the fracture is not properly immobilized.
• Chronic pain or stiffness in the wrist.
• Nerve or tendon irritation due to swelling or fracture fragments.
• Post-traumatic arthritis in severe cases.

Lifestyle & Prevention

• Wear protective gear during high-risk activities (e.g., sports, manual labor).
• Maintain bone health through a balanced diet and regular exercise.
• Avoid falls by using assistive devices if balance is impaired.
• Warm up and stretch before physical activities to reduce injury risk.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, inability to move the wrist, visible deformity, 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 (right wrist) and fracture type (nondisplaced) to ensure accurate coding. Include details about the mechanism of injury, imaging results, and treatment plan to support medical necessity. Verify that the fracture is confirmed by imaging and that no displacement is noted in clinical records.
