S62.163 Displaced fracture of pisiform, unspecified wrist

Name of the Condition

• Displaced fracture of pisiform, unspecified wrist

Summary

This condition involves a break in the pisiform bone of the 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 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: Medications to reduce pain and inflammation.
• Surgical intervention: Required in cases of severe displacement or instability, involving realignment and fixation of the bone fragments.
• Rehabilitation: Physical therapy to restore strength and range of motion after healing.

Prognosis and Follow-Up

Most fractures heal with proper treatment, but recovery time depends on the severity of the injury and treatment approach. Follow-up appointments monitor healing progress, and rehabilitation may be necessary to regain full function. Complications, such as chronic pain or reduced mobility, can occur if the fracture is not properly managed.

Complications

• Chronic pain or discomfort in the wrist.
• Reduced range of motion or stiffness.
• Nerve or tendon damage due to displacement.
• Nonunion or malunion of the fracture if untreated or improperly aligned.

Lifestyle & Prevention

• Use 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.
• Seek prompt medical attention for wrist injuries to prevent complications.

When to Seek Professional Help

Consult a healthcare provider if you experience severe wrist pain, swelling, or deformity after an injury. Immediate care is needed if you cannot move your wrist, experience numbness, or have signs of infection (e.g., redness, fever).

Tips for Medical Coders

Document the specific wrist side (right/left) if known, as this may impact coding specificity. For unspecified wrist, use this code when the side is not documented. Ensure trauma details and displacement are clearly recorded to support the diagnosis.
