S62.162S Displaced fracture of pisiform, left wrist, sequela

Name of the Condition

• Displaced fracture of pisiform, left wrist, sequela

Summary

This condition represents a displaced fracture of the pisiform bone in the left wrist that has reached the sequela stage, meaning it is a residual effect or chronic condition following the initial injury. The pisiform is a small, pea-shaped carpal bone on the palmar (palm) side of the wrist, embedded within the flexor carpi ulnaris tendon. At the sequela stage, the fracture has healed, but residual effects such as persistent pain, limited mobility, or deformity may remain. This stage indicates the injury is no longer acute and has transitioned to a chronic state.

Causes

The sequela arises from a prior displaced fracture of the pisiform bone in the left wrist, 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 initial injury may have been open or closed, but the sequela reflects the long-term consequences of that fracture.

Risk Factors

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

Symptoms

• Chronic pain or discomfort in the palmar side of the left wrist.
• Persistent swelling or tenderness at the injury site.
• Limited range of motion or stiffness in the wrist or hand.
• Possible deformity or altered alignment of the pisiform bone.
• Reduced grip strength or functional impairment.

Diagnosis

Diagnosis involves a detailed patient history to confirm prior wrist injury and a physical examination to assess residual symptoms, such as pain, swelling, or mobility limitations. Imaging studies, including X-rays or MRI, may be used to evaluate the healed fracture and identify any persistent displacement or associated complications. The sequela stage is confirmed by the absence of acute injury signs and the presence of chronic effects.

Treatment Options

Treatment focuses on managing residual symptoms and improving function. Options may include physical therapy to restore mobility and strength, pain management with medications or injections, and adaptive devices to assist with daily activities. In severe cases, surgical intervention to address persistent deformity or instability may be considered, though this is less common at the sequela stage.

Prognosis and Follow-Up

Prognosis depends on the severity of the initial injury and the effectiveness of healing. Most patients experience improvement in symptoms with conservative management, though some may have permanent limitations. Regular follow-up is recommended to monitor for complications and adjust treatment as needed. Long-term outcomes are generally favorable with appropriate care.

Complications

• Chronic pain or persistent discomfort.
• Reduced wrist mobility or stiffness.
• Grip weakness or functional impairment.
• Arthritis or degenerative changes in the wrist over time.
• Nerve or tendon irritation due to altered bone alignment.

Lifestyle & Prevention

• Avoid activities that stress the wrist, such as heavy lifting or repetitive motions.
• Use wrist supports or braces during activities to reduce strain.
• Maintain overall bone health with a balanced diet and regular exercise.
• Seek prompt treatment for new wrist injuries to prevent long-term sequelae.

When to Seek Professional Help

Consult a healthcare provider if you experience worsening pain, new swelling, or a decrease in wrist function. Seek immediate care for signs of infection, such as redness, warmth, or fever, or if you notice sudden changes in sensation or movement.

Tips for Medical Coders

This code is used for a displaced fracture of the pisiform, left wrist, at the sequela stage. Document the residual effects of the prior injury, including chronic symptoms and functional limitations. Ensure the diagnosis clearly indicates the sequela stage and specify the left wrist and pisiform bone. Coding should reflect the chronic nature of the condition and any associated complications.
