S62.16 Fracture of pisiform

Name of the Condition

• Fracture of pisiform

Summary

This condition refers to a break or crack in the pisiform bone, a small, pea-shaped carpal bone located on the palmar (palm) side of the wrist. The pisiform is embedded within the flexor carpi ulnaris tendon and plays a role in wrist stability and movement. Fractures in this area typically result from trauma and may vary in severity, with or without displacement of bone fragments.

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 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.

Prognosis and Follow-Up

Most fractures of the pisiform heal well with appropriate immobilization and care. Follow-up imaging may be recommended to ensure proper healing. Recovery time varies depending on fracture severity and treatment, but most patients regain full function with minimal long-term effects.

Complications

• Nonunion or delayed healing of the fracture.
• Persistent pain or stiffness in the wrist.
• Nerve or tendon irritation due to fracture fragments or swelling.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Maintain bone health through adequate calcium and vitamin D intake.
• Avoid repetitive wrist stress or trauma when possible.

When to Seek Professional Help

Seek medical attention if you experience severe wrist pain, swelling, or deformity after an injury, or if symptoms worsen despite initial care.

Tips for Medical Coders

Document the specific location (pisiform bone) and any associated details, such as displacement or open fracture, to support accurate coding. Ensure clinical documentation aligns with the fracture type and severity for proper code assignment.
