S62.175G Nondisplaced fracture of trapezium [larger multangular], left wrist, subsequent encounter for fracture with delayed healing

Name of the Condition

• Nondisplaced fracture of trapezium [larger multangular], left wrist, subsequent encounter for fracture with delayed healing

Summary

This condition refers to a break in the trapezium bone of the left wrist without displacement of bone fragments, occurring during a subsequent encounter for a fracture with delayed healing. The trapezium is a small carpal bone at the base of the thumb, essential for thumb movement and grip. Nondisplaced fractures mean the bone fragments remain aligned, but delayed healing indicates the fracture is not progressing as expected during the healing process.

Causes

Typically caused by direct trauma to the wrist, such as a fall onto an outstretched hand, a blow to the wrist, or a twisting injury. High-impact activities or accidents may also lead to fractures in this specific bone. Delayed healing can result from factors like poor blood supply, inadequate immobilization, or underlying health conditions affecting bone repair.

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.
• Smoking or poor nutrition, which can impair bone healing.

Symptoms

• Persistent pain, swelling, and tenderness at the base of the thumb.
• Bruising or discoloration around the injury site.
• Limited range of motion or difficulty moving the thumb.
• Visible deformity in severe cases.
• Prolonged healing time compared to typical fracture recovery.

Diagnosis

Physical examination to assess pain, swelling, and thumb mobility. Imaging tests, such as X-rays, CT scans, or MRIs, to confirm the fracture and evaluate its extent and alignment. Additional tests may be used to assess healing progress and identify causes of delayed healing.

Treatment Options

• Immobilization: Continued use of a cast, splint, or brace to stabilize the area and promote healing.
• Pain management: Medications to reduce discomfort and inflammation.
• Physical therapy: Exercises to restore range of motion and strength once healing allows.
• Surgical intervention: Considered if delayed healing persists or complications arise.

Prognosis and Follow-Up

Prognosis depends on the underlying cause of delayed healing and adherence to treatment. Most nondisplaced fractures heal with proper care, but delayed healing may extend recovery time. Regular follow-up appointments are necessary to monitor progress and adjust treatment as needed.

Complications

• Chronic pain or stiffness in the wrist or thumb.
• Nonunion or malunion of the fracture.
• Arthritis in the affected joint over time.
• Reduced grip strength or functional impairment.

Lifestyle & Prevention

• Avoid high-risk activities until fully healed.
• Maintain a healthy diet rich in calcium and vitamin D to support bone health.
• Use protective gear during sports or activities with fall risks.
• Quit smoking, as it can hinder bone healing.

When to Seek Professional Help

Seek medical attention if pain worsens, swelling increases, or mobility does not improve. Contact a healthcare provider if signs of infection (e.g., redness, fever) or new deformity appear.

Tips for Medical Coders

Document the encounter as a subsequent visit for fracture with delayed healing. Include details on the fracture's status, treatment provided, and any factors contributing to delayed healing. Ensure the left wrist and trapezium bone are clearly specified in the record.
