S62.152S Displaced fracture of hook process of hamate [unciform] bone, left wrist, sequela

Name of the Condition

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

Summary

This condition represents a displaced fracture of the hook process of the hamate bone in the left wrist, classified as a sequela (a residual effect of a previous injury or condition). The hamate bone is a small carpal bone on the ulnar (pinky) side of the wrist, and its hook process contributes to wrist stability and grip. Displacement means the bone fragments are misaligned, which may persist and affect function. Sequela indicates this is a chronic or long-term outcome of an earlier fracture, requiring evaluation to assess residual impairment and guide management.

Causes

Typically results from prior trauma to the wrist, such as a fall, blow, or twisting injury that caused the initial fracture. The sequela classification implies the current condition is a consequence of that original event, with displacement remaining unresolved or leading to persistent symptoms.

Risk Factors

• History of wrist trauma or fracture, particularly involving the hamate bone.
• Inadequate initial treatment or healing of the original fracture.
• Activities or occupations involving repetitive wrist stress or forceful gripping.
• Underlying conditions affecting bone healing, such as poor circulation or metabolic disorders.

Symptoms

• Chronic pain, swelling, or tenderness on the ulnar side of the left wrist.
• Reduced range of motion or grip strength in the wrist or hand.
• Possible clicking, catching, or instability during wrist movement.
• Visible or palpable deformity in severe cases.

Diagnosis

Clinical evaluation focuses on assessing residual symptoms, functional impairment, and prior injury history. Imaging, such as X-rays or CT scans, may be used to confirm displacement and evaluate bone healing. The sequela designation is based on the chronic nature of the condition and its link to a previous fracture.

Treatment Options

Management depends on symptom severity and functional impact. Options may include:

• Immobilization with a splint or cast to stabilize the wrist.
• Physical therapy to improve strength and range of motion.
• Pain management with medications or injections.
• Surgical intervention, such as osteotomy or fixation, for persistent displacement or functional impairment.

Prognosis and Follow-Up

Prognosis varies based on the extent of residual displacement and functional limitations. Regular follow-up is important to monitor healing, address ongoing symptoms, and adjust treatment. Long-term outcomes may include reduced wrist function or chronic pain, depending on the severity of the sequela.

Complications

• Chronic pain or stiffness in the wrist.
• Persistent instability or weakness affecting grip or dexterity.
• Post-traumatic arthritis due to misalignment or joint stress.
• Nerve compression or irritation from displaced bone fragments.

Lifestyle & Prevention

• Avoid activities that stress the wrist, especially forceful gripping or repetitive motions.
• Use protective gear during sports or high-risk activities.
• Maintain bone health through proper nutrition and exercise to support healing.
• Follow rehabilitation guidelines to optimize recovery and minimize long-term effects.

When to Seek Professional Help

Seek care if you experience worsening pain, swelling, or reduced function in the left wrist, or if you notice new deformity or instability. Prompt evaluation is important for managing sequela and preventing further complications.

Tips for Medical Coders

This code (S62.152S) is used for a displaced fracture of the hook process of the hamate bone in the left wrist, classified as a sequela. Documentation should clearly indicate the residual effects of a prior fracture, including the chronic nature of the condition and its impact on function. Ensure the sequela designation aligns with the patient’s history and clinical findings to support accurate coding.
