S62.161S Displaced fracture of pisiform, right wrist, sequela

Name of the Condition

• Displaced fracture of pisiform, right wrist, sequela

Summary

This condition represents a displaced fracture of the pisiform bone in the right wrist, classified as a sequela. The pisiform is a small, pea-shaped carpal bone on the palmar (palm) side of the wrist, embedded in the flexor carpi ulnaris tendon. A sequela indicates this is a residual effect or complication following the initial injury, where the fracture has healed but may result in persistent symptoms or functional impairment. Displacement of the bone fragments during the original injury can lead to long-term issues such as altered wrist mechanics or chronic pain.

Causes

The sequela arises from a prior displaced fracture of the pisiform bone in the right wrist. The initial injury was typically caused by direct trauma, such as a fall onto an outstretched hand, a blow to the palmar side of the wrist, or a crushing injury. The sequela develops as a result of the healing process or incomplete resolution of the original fracture.

Risk Factors

• History of wrist trauma or fracture, particularly involving the pisiform bone.
• Inadequate initial treatment or nonunion of the original fracture.
• Underlying conditions affecting bone healing, such as osteoporosis or poor circulation.

Symptoms

• Chronic pain or discomfort in the palmar side of the right wrist.
• Reduced range of motion or stiffness in the wrist or hand.
• Persistent swelling or tenderness at the injury site.
• Possible weakness or instability during wrist movement.

Diagnosis

Diagnosis involves a review of the patient's medical history, focusing on the original injury and its treatment. Physical examination assesses wrist function, pain, and any residual deformity. Imaging studies, such as X-rays or CT scans, may be used to evaluate the healed fracture and identify any malalignment or degenerative changes. The presence of a sequela is confirmed by correlating current symptoms with the history of the prior fracture.

Treatment Options

Treatment focuses on managing symptoms and improving function. This may include physical therapy to restore mobility and strength, pain management with medications or injections, and adaptive devices to support wrist use. In some cases, surgical intervention may be considered to address persistent instability or deformity.

Prognosis and Follow-Up

Prognosis depends on the severity of the original injury and the effectiveness of treatment. Many patients experience improved function with conservative management, though some may have long-term limitations. Regular follow-up is important to monitor healing and address any new symptoms or complications.

Complications

• Chronic pain or arthritis in the wrist joint.
• Persistent instability or reduced grip strength.
• Nerve compression or tendon irritation due to malalignment.
• Limited mobility affecting daily activities.

Lifestyle & Prevention

• Avoid repetitive or high-impact activities that stress the wrist.
• Use protective gear during sports or activities with fall risks.
• Maintain bone health through proper nutrition and exercise to support overall skeletal strength.

When to Seek Professional Help

Seek medical attention if symptoms worsen, new pain or swelling develops, or there is a noticeable decrease in wrist function. Prompt evaluation is important to rule out new injuries or complications.

Tips for Medical Coders

This code is used for a displaced fracture of the pisiform, right wrist, sequela. Document the history of the original injury, the nature of the sequela (e.g., chronic pain, functional impairment), and any relevant treatment or follow-up. Ensure the sequela is clearly linked to the prior fracture to support accurate coding.
