S62.142S Displaced fracture of body of hamate [unciform] bone, left wrist, sequela

Name of the Condition

• Displaced fracture of body of hamate [unciform] bone, left wrist, sequela

Summary

This condition represents a displaced fracture of the body of the hamate bone in the left wrist, classified as a sequela. The hamate is a small carpal bone on the ulnar (pinky) side of the wrist, contributing to stability and grip. A sequela indicates this is a residual effect or complication following the initial injury, where displaced bone fragments may have healed in an abnormal position, potentially affecting wrist function. Management focuses on addressing long-term consequences of the fracture.

Causes

The sequela arises from a prior displaced fracture of the hamate bone, typically caused by direct trauma such as a fall onto an outstretched hand, a blow to the wrist, or a crushing injury. The initial fracture may have occurred during high-impact activities, accidents, or sports-related incidents, leading to displacement and subsequent healing complications.

Risk Factors

• Participation in contact sports or activities with a high risk of wrist trauma.
• Osteoporosis or weakened bone structure, increasing fracture risk and healing challenges.
• Previous wrist injuries or fractures, which may predispose to long-term complications.
• Inadequate initial treatment or nonunion of the original fracture.

Symptoms

• Chronic pain, swelling, or tenderness on the ulnar side of the left wrist.
• Reduced range of motion or difficulty gripping objects.
• Persistent instability or weakness in the wrist.
• Possible nerve compression symptoms, such as numbness or tingling in the hand.

Diagnosis

Physical examination to assess chronic pain, swelling, and wrist mobility. Imaging tests, such as X-rays, CT scans, or MRIs, to evaluate the healed fracture, alignment, and any residual displacement. Clinical correlation with the patient’s history of the initial injury is essential to confirm the sequela.

Treatment Options

Treatment depends on symptom severity and functional impact. Options may include physical therapy to improve strength and mobility, pain management, or surgical intervention for persistent instability or nerve compression. Orthotic devices or activity modification may also be recommended to support wrist function.

Prognosis and Follow-Up

Prognosis varies based on the extent of residual displacement and functional impairment. Regular follow-up with a healthcare provider is important to monitor healing, address complications, and adjust treatment as needed. Long-term outcomes may include improved function with therapy or persistent limitations requiring ongoing management.

Complications

• Chronic pain or arthritis in the wrist joint.
• Nerve damage or compression, leading to sensory or motor deficits.
• Reduced grip strength or wrist instability.
• Delayed union or malunion of the fracture.

Lifestyle & Prevention

• Avoid high-impact activities that stress the wrist.
• Use protective gear during sports or manual labor.
• Maintain bone health through proper nutrition and exercise.
• Follow post-injury rehabilitation protocols to minimize long-term effects.

When to Seek Professional Help

Seek medical attention if experiencing worsening pain, new numbness or tingling, or difficulty moving the wrist. Persistent symptoms or functional limitations after initial treatment warrant evaluation to address potential complications.

Tips for Medical Coders

This code (S62.142S) is used for a displaced fracture of the hamate bone in the left wrist, classified as a sequela. Documentation should clearly indicate the residual effects of a prior fracture, including details of the initial injury, healing status, and current symptoms. Ensure the sequela is linked to the original fracture and that the left wrist and displacement are specified. Avoid using this code for acute fractures or initial encounters.
