S62.165 Nondisplaced fracture of pisiform, left wrist

Name of the Condition

• Nondisplaced fracture of pisiform, left wrist

Summary

This condition refers to a break in the pisiform bone of the left 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 are characterized by the absence of bone fragment displacement, which may help preserve wrist stability and function.

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 left 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 promote healing.
• Pain management: Over-the-counter or prescription medications to reduce pain and inflammation.
• Physical therapy: Exercises to restore wrist strength and range of motion after immobilization.
• Surgical intervention: Rarely required for nondisplaced fractures, but may be considered if conservative treatment fails.

Prognosis and Follow-Up

Most nondisplaced fractures of the pisiform heal well with proper immobilization and follow-up care. Recovery time typically ranges from 4 to 6 weeks, depending on the severity of the injury. Regular follow-up appointments with a healthcare provider are recommended to monitor healing and adjust treatment as needed.

Complications

• Delayed union or nonunion of the fracture.
• Chronic pain or stiffness in the wrist.
• Nerve or tendon damage in severe cases.
• Post-traumatic arthritis.

Lifestyle & Prevention

• Use protective gear during high-risk activities, such as wrist guards in sports.
• Maintain bone health through a balanced diet rich in calcium and vitamin D.
• Avoid falls by using assistive devices if balance is impaired.
• Practice proper wrist mechanics during repetitive tasks.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, swelling, or deformity in the left wrist, or if you cannot move your hand or fingers. Contact a healthcare provider if symptoms worsen or do not improve with home care.

Tips for Medical Coders

Document the specific location (left wrist) and fracture type (nondisplaced) to ensure accurate coding. Include details about the mechanism of injury, diagnostic imaging results, and treatment plan to support medical necessity. Verify that the fracture is not associated with other wrist injuries or complications that may require additional coding.
