S62.161 Displaced fracture of pisiform, right wrist

Name of the Condition

• Displaced fracture of pisiform, right wrist

Summary

This condition involves a break in the pisiform bone of the right wrist where the bone fragments are displaced from their normal position. The pisiform is a small, pea-shaped carpal bone located on the palmar (palm) side of the wrist, near the base of the pinky finger. Displacement occurs when the broken bone fragments shift, potentially affecting wrist stability and function. Fractures in this area typically result from trauma and may vary in severity, with displacement indicating a more significant injury.

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 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 or unstable fractures.

Prognosis and Follow-Up

Most displaced fractures of the pisiform heal with proper immobilization and follow-up care. Recovery time varies but typically ranges from 6 to 8 weeks. Regular follow-up appointments are necessary to monitor healing and adjust treatment as needed. Long-term outcomes depend on the severity of the fracture and adherence to rehabilitation.

Complications

• Chronic pain or stiffness in the wrist.
• Nonunion or malunion of the fracture.
• Nerve or tendon damage due to displacement.
• Reduced grip strength or functional impairment.

Lifestyle & Prevention

• Wear protective gear during high-risk activities.
• Maintain bone health through a balanced diet and exercise.
• Avoid falls by using assistive devices if needed.
• Strengthen wrist muscles through targeted exercises.

When to Seek Professional Help

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

Tips for Medical Coders

Document the specific bone (pisiform), laterality (right), and displacement status clearly. Ensure clinical notes support the diagnosis and treatment provided. Use this code only when the pisiform is explicitly identified as fractured and displaced.
