S62.318S Displaced fracture of base of other metacarpal bone, sequela

Name of the Condition

• Displaced fracture of base of other metacarpal bone, sequela

Summary

A displaced fracture of the base of another metacarpal bone, sequela, refers to the residual effects of a previously healed fracture in the proximal (base) portion of one of the hand bones (excluding the thumb), where the bone fragments remain misaligned. This condition represents the long-term consequences of the initial injury, potentially leading to persistent pain, functional limitations, or structural changes in the affected hand.

Causes

The sequela arises from a prior displaced fracture of the metacarpal base, typically resulting from trauma such as a fall, blow to the hand, or sports-related injury. The initial fracture may have been incomplete or improperly aligned during healing, leading to chronic issues.

Risk Factors

• History of prior hand trauma or fracture.
• Inadequate initial treatment or immobilization of the original fracture.
• Pre-existing conditions affecting bone healing, such as osteoporosis or poor circulation.

Symptoms

• Chronic pain or discomfort in the hand, particularly with movement.
• Reduced range of motion or stiffness in the affected fingers.
• Visible or palpable deformity at the metacarpal base.
• Weakness or difficulty gripping objects.

Diagnosis

Physical examination to assess residual deformity, tenderness, or functional impairment. Imaging tests, such as X-rays, to evaluate the alignment and healing status of the metacarpal base. Review of prior medical records to confirm the history of the original fracture.

Treatment Options

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

Prognosis and Follow-Up

Prognosis depends on the severity of the residual displacement and the patient’s response to treatment. Regular follow-up with a healthcare provider is recommended to monitor for complications, such as arthritis or chronic pain. Long-term management may focus on symptom relief and maintaining hand function.

Complications

• Chronic pain or arthritis in the affected joint.
• Persistent deformity or reduced grip strength.
• Nerve or tendon irritation due to misalignment.
• Increased risk of future fractures in the weakened area.

Lifestyle & Prevention

• Avoid repetitive or high-impact activities that stress the hand.
• Use protective gear during sports or manual labor.
• Perform hand-strengthening exercises as recommended by a therapist.
• Maintain bone health through proper nutrition and exercise.

When to Seek Professional Help

Seek care if symptoms worsen, new pain or swelling develops, or functional limitations interfere with daily activities. Prompt evaluation is necessary if signs of infection, such as redness or drainage, appear at the site.

Tips for Medical Coders

Document the history of the original fracture and the nature of the sequela, including any persistent misalignment or functional impairment. Ensure the code S62.318S is used only for sequelae of a displaced metacarpal base fracture, with clear linkage to the prior injury in the medical record.
