S92.311S Displaced fracture of first metatarsal bone, right foot, sequela

Name of the Condition

• Displaced fracture of first metatarsal bone, right foot, sequela
• ICD-10 Code: S92.311S

Summary

This condition represents a displaced fracture of the first metatarsal bone in the right foot that has reached the sequela stage. A sequela indicates the condition is a late effect or residual after the acute phase of the injury. The first metatarsal is a critical weight-bearing bone, and displacement means the bone fragments are no longer in their normal alignment. This stage reflects the long-term consequences of the initial fracture, such as persistent pain, deformity, or functional impairment.

Causes

The sequela arises from a prior displaced fracture of the first metatarsal bone in the right foot. The original injury was likely caused by direct trauma, such as a fall, sports injury, or high-impact event. Inadequate healing, malunion, or nonunion of the initial fracture can lead to chronic symptoms and structural changes, resulting in the sequela.

Risk Factors

• Inadequate initial treatment or non-compliance with rehabilitation
• Poor bone healing due to underlying conditions (e.g., osteoporosis, diabetes)
• High-impact activities that stress the foot
• Previous foot injuries or fractures
• Advanced age, which may impair bone repair and recovery

Symptoms

• Chronic pain in the right foot, particularly during weight-bearing
• Persistent swelling or deformity of the first metatarsal area
• Reduced range of motion in the big toe or midfoot
• Difficulty walking or performing daily activities
• Possible numbness or tingling if nerve involvement is present

Diagnosis

A healthcare provider will evaluate the history of the initial fracture and assess current symptoms. Physical examination focuses on pain, deformity, and functional limitations. Imaging, such as X-rays or MRI, may be used to confirm the sequela and assess bone alignment or healing. The diagnosis is based on the persistence of symptoms beyond the expected recovery period for the original injury.

Treatment Options

Treatment aims to manage symptoms and improve function. Options may include pain management, physical therapy to restore mobility, orthotic devices for support, or surgical intervention if deformity or instability is severe. The approach depends on the extent of residual damage and the patient’s functional needs.

Prognosis and Follow-Up

Prognosis varies based on the severity of the sequela and response to treatment. Some patients experience long-term discomfort or reduced mobility, while others may regain near-normal function with appropriate care. Regular follow-up is important to monitor symptoms and adjust treatment as needed.

Complications

• Chronic pain or arthritis in the affected joint
• Persistent deformity affecting gait or footwear
• Nerve damage leading to numbness or weakness
• Reduced quality of life due to activity limitations

Lifestyle & Prevention

• Wear supportive footwear to reduce stress on the foot
• Avoid high-impact activities that exacerbate symptoms
• Maintain a healthy weight to minimize joint strain
• Engage in low-impact exercises (e.g., swimming) to preserve mobility
• Follow post-injury rehabilitation protocols to optimize healing

When to Seek Professional Help

Seek care if chronic pain worsens, swelling increases, or functional limitations impact daily life. New deformity, numbness, or signs of infection (e.g., redness, fever) also require prompt evaluation.

Tips for Medical Coders

This code is used for a displaced fracture of the first metatarsal bone in the right foot at the sequela stage. Document the history of the initial injury, current symptoms, and evidence of residual effects (e.g., imaging, clinical findings) to support the sequela designation. Ensure the code aligns with the patient’s active problem list and reflects the chronic nature of the condition.
