S62.315S Displaced fracture of base of fourth metacarpal bone, left hand, sequela

Name of the Condition

• Displaced fracture of base of fourth metacarpal bone, left hand, sequela

Summary

A displaced fracture of the base of the fourth metacarpal bone in the left hand, sequela, refers to the residual effects or complications following a previous fracture of this area. This condition involves misalignment of the bone fragments at the proximal (base) portion of the fourth metacarpal, which may result in persistent pain, functional limitations, or structural changes in the hand. The sequela designation indicates this is a late effect of the initial injury, rather than an active fracture.

Causes

The sequela arises from a prior displaced fracture of the base of the fourth metacarpal bone in the left hand. The original injury typically resulted from trauma, such as a fall, direct impact, or high-force event affecting the hand. Incomplete healing, malunion, or inadequate treatment of the initial fracture can lead to long-term consequences.

Risk Factors

• History of a previous fracture in the left hand, particularly the fourth metacarpal.
• Inadequate immobilization or rehabilitation following the initial injury.
• Underlying conditions affecting bone healing, such as poor circulation or metabolic disorders.
• Advanced age or reduced bone density, which may impair recovery.

Symptoms

• Chronic pain or discomfort in the left hand, especially around the base of the fourth metacarpal.
• Reduced range of motion or stiffness in the affected finger or wrist.
• Visible or palpable deformity at the fracture site.
• Weakness or difficulty gripping objects.
• Possible swelling or tenderness in the area.

Diagnosis

A healthcare provider evaluates the patient’s history of the initial injury and current symptoms. Physical examination assesses for deformity, tenderness, or functional limitations. Imaging, such as X-rays, may be used to confirm residual misalignment or structural changes. The diagnosis is based on the presence of long-term effects following a prior fracture.

Treatment Options

• Pain management with medications or physical therapy to improve mobility.
• Orthotic devices or splints to support the hand and reduce strain.
• Surgical intervention, if severe misalignment or functional impairment persists.
• Occupational therapy to adapt daily activities and prevent further injury.

Prognosis and Follow-Up

Prognosis depends on the severity of the residual effects and the patient’s response to treatment. Many individuals experience improved function with therapy, though some may have permanent limitations. Regular follow-up appointments monitor healing and adjust treatment plans as needed.

Complications

• Chronic pain or arthritis in the affected joint.
• Persistent deformity or reduced hand function.
• Nerve or tendon damage from the original injury or subsequent changes.
• Increased risk of re-injury due to weakened bone or altered mechanics.

Lifestyle & Prevention

• Avoid activities that strain the left hand, especially those involving repetitive gripping or impact.
• Use protective gear during sports or manual labor to prevent new injuries.
• Engage in exercises recommended by a healthcare provider to maintain strength and flexibility.
• Maintain overall bone health through proper nutrition and regular check-ups.

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 important if signs of infection, such as redness or fever, appear at the site.

Tips for Medical Coders

This code is used for the sequela of a displaced fracture of the base of the fourth metacarpal bone in the left hand. Documentation should specify the nature of the residual effects, such as chronic pain, deformity, or functional impairment, and link them to the prior injury. Ensure the code is applied only when the condition represents a late effect rather than an active fracture.
