S62.324S Displaced fracture of shaft of fourth metacarpal bone, right hand, sequela

Name of the Condition

• Displaced fracture of shaft of fourth metacarpal bone, right hand, sequela

Summary

A displaced fracture of the shaft of the fourth metacarpal bone in the right hand, sequela, refers to a residual condition resulting from a previous fracture of the bone's middle portion. The term "sequela" indicates this is a complication or long-term effect of the initial injury, where the bone fragments remain misaligned or healing has led to persistent structural changes. This condition typically arises after the acute phase of the fracture has resolved, and it may involve chronic pain, deformity, or functional limitations.

Causes

The sequela develops as a result of a prior displaced fracture of the fourth metacarpal bone in the right hand. The initial injury, often caused by trauma such as a fall, blow, or accident, disrupts the bone's alignment, and incomplete healing or malunion leads to the residual effects.

Risk Factors

• Inadequate initial treatment or immobilization of the fracture.
• Delayed or incomplete healing of the original injury.
• High-impact activities or manual labor that stress the hand.
• Pre-existing conditions like osteoporosis that affect bone healing.

Symptoms

• Chronic pain or discomfort in the right hand.
• Persistent swelling or tenderness around the affected area.
• Reduced range of motion or stiffness in the fingers.
• Visible deformity or misalignment of the hand.
• Difficulty gripping or performing fine motor tasks.

Diagnosis

Physical examination to assess residual deformity, tenderness, or functional limitations. Imaging tests, such as X-rays, to evaluate the bone's alignment and healing status. Review of the patient's medical history to confirm the prior fracture and its treatment.

Treatment Options

• Orthotic devices or splints to support the hand and improve function.
• Pain management with medications or physical therapy.
• Surgical intervention, if severe deformity or functional impairment exists, to realign the bone.
• Occupational therapy to adapt daily activities and reduce strain.

Prognosis and Follow-Up

Prognosis depends on the severity of the residual deformity and the patient's adherence to treatment. Most patients experience improved function with appropriate care, though some may have permanent limitations. Regular follow-up appointments monitor healing and adjust treatment as needed.

Complications

• Chronic pain or arthritis in the affected joint.
• Persistent deformity affecting hand appearance or function.
• Reduced grip strength or dexterity.
• Increased risk of future fractures in the same area.

Lifestyle & Prevention

• Avoid activities that strain the right hand or risk re-injury.
• Use protective gear during sports or manual work.
• Perform hand-strengthening exercises as recommended by a healthcare provider.
• Maintain bone health through a balanced diet and regular exercise.

When to Seek Professional Help

Seek care if symptoms worsen, new pain or swelling develops, or functional limitations interfere with daily tasks. Prompt evaluation is necessary if signs of infection or nerve damage appear, such as redness, warmth, or numbness.

Tips for Medical Coders

Document the sequela clearly, noting the prior fracture and its impact on current function. Ensure the code S62.324S is used only when the condition is a residual effect of a previous injury, not an acute fracture. Include details about the nature of the sequela (e.g., deformity, chronic pain) to support coding accuracy.
