S62.339S Displaced fracture of neck of unspecified metacarpal bone, sequela

Name of the Condition

• Displaced fracture of neck of unspecified metacarpal bone, sequela

Summary

A displaced fracture of the neck of an unspecified metacarpal bone, sequela, refers to the residual effects or chronic changes resulting from a prior displaced fracture at the neck of one of the hand's metacarpal bones (excluding the thumb). This condition occurs after the initial healing phase and may involve persistent misalignment, functional impairment, or long-term complications from the original injury.

Causes

The sequela arises from a previous displaced fracture of the metacarpal neck, typically caused by direct trauma such as a fall onto an outstretched hand, a blow to the hand, or high-impact injuries. The residual effects develop as a result of incomplete healing, malunion, or chronic stress on the fractured bone.

Risk Factors

• Prior history of metacarpal neck fracture.
• Inadequate initial treatment or immobilization.
• High-impact activities or occupations involving repetitive hand use.
• Reduced bone density or osteoporosis, which may affect healing.

Symptoms

• Persistent pain or discomfort in the affected hand.
• Limited range of motion or stiffness in the fingers or wrist.
• Visible or palpable deformity at the fracture site.
• Weakness or reduced grip strength.
• Possible swelling or tenderness in the long term.

Diagnosis

Clinical evaluation focuses on assessing residual functional impairment, deformity, and pain. Imaging, such as X-rays or CT scans, may be used to evaluate bone alignment, healing, or associated degenerative changes. A history of the original fracture is critical for diagnosis.

Treatment Options

• Orthotic devices or splints to support function and reduce pain.
• Physical therapy to improve mobility and strength.
• Pain management with medications or injections.
• Surgical intervention in cases of significant deformity or functional impairment.
• Adaptive equipment for daily activities, if needed.

Prognosis and Follow-Up

Prognosis depends on the severity of the original injury, treatment, and individual factors. Most patients experience improved function with rehabilitation, though some may have permanent limitations. Regular follow-up with a healthcare provider is recommended to monitor for complications or further intervention.

Complications

• Chronic pain or arthritis in the affected joint.
• Persistent deformity or malunion.
• Reduced grip strength or dexterity.
• Nerve or tendon irritation from misaligned bone.
• Psychological impact from long-term functional limitations.

Lifestyle & Prevention

• Avoid repetitive or high-impact hand activities that may exacerbate symptoms.
• Use ergonomic tools or protective gear during work or sports.
• Engage in regular hand exercises to maintain mobility.
• Maintain bone health through proper nutrition and exercise to support overall skeletal strength.

When to Seek Professional Help

Seek care if you experience increasing pain, new deformity, or loss of function in the hand. Prompt evaluation is necessary for worsening symptoms or signs of infection, such as redness, warmth, or discharge.

Tips for Medical Coders

Document the sequela status clearly, noting the prior fracture and its residual effects. Ensure the medical record supports the chronic nature of the condition and any associated functional limitations. Code S62.339S is appropriate for follow-up care related to the long-term effects of the original injury.
