S62.323P Displaced fracture of shaft of third metacarpal bone, left hand, subsequent encounter for fracture with malunion

Name of the Condition

• Displaced fracture of shaft of third metacarpal bone, left hand, subsequent encounter for fracture with malunion

Summary

A displaced fracture of the shaft of the third metacarpal bone in the left hand, with malunion, refers to a healed fracture where the bone fragments have misaligned during the healing process. This condition occurs after initial treatment and involves a fracture that has not healed in its normal anatomical position, potentially affecting hand function.

Causes

Direct trauma, such as a fall or blow to the hand. Inadequate immobilization during initial healing. Poor blood supply to the fracture site. Delayed or incomplete treatment of the initial fracture.

Risk Factors

• Participation in contact sports or high-impact activities.
• Reduced bone density or osteoporosis.
• Occupational hazards involving manual labor.
• History of prior hand injuries or fractures.

Symptoms

• Persistent pain or discomfort in the hand.
• Swelling or tenderness around the affected area.
• Difficulty moving the fingers or hand.
• Visible or palpable deformity at the fracture site.
• Reduced grip strength or functional impairment.

Diagnosis

Physical examination by a healthcare provider to assess tenderness, swelling, deformity, or functional limitations. Imaging tests, such as X-rays, to evaluate the fracture alignment and healing status. Assessment of range of motion and grip strength.

Treatment Options

• Orthopedic evaluation to determine the need for intervention.
• Pain management using over-the-counter or prescription medications.
• Physical therapy to improve mobility and strength.
• Surgical correction (e.g., osteotomy) for severe malunion affecting function.
• Custom orthotics or splinting to support alignment.

Prognosis and Follow-Up

Prognosis depends on the severity of malunion and functional impact. Most patients experience improved function with treatment, but residual limitations may persist. Regular follow-up with an orthopedic specialist is recommended to monitor healing and address complications.

Complications

• Chronic pain or discomfort.
• Reduced hand mobility or grip strength.
• Arthritis or joint degeneration due to misalignment.
• Nerve or tendon irritation from abnormal bone position.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Use protective gear during sports or manual labor.
• Maintain bone health through adequate nutrition and exercise.
• Follow post-treatment guidelines to support proper healing.

When to Seek Professional Help

Seek care if pain worsens, swelling increases, or hand function declines. Consult a healthcare provider if deformity is noticeable or if daily activities are impaired.

Tips for Medical Coders

Document the presence of malunion and subsequent encounter details clearly. Include clinical notes confirming fracture healing status and functional impact. Ensure documentation supports the need for ongoing care or intervention related to the malunion.
