S92.312S Displaced fracture of first metatarsal bone, left foot, sequela

Name of the Condition

• Displaced fracture of first metatarsal bone, left foot, sequela
• ICD-10 Code: S92.312S

Summary

A displaced fracture of the first metatarsal bone in the left foot, sequela, refers to a residual effect or complication following a previous fracture. The first metatarsal is a key weight-bearing bone in the foot, and displacement means the bone fragments remain out of alignment after the initial injury has healed. This condition may result in persistent pain, altered gait, or reduced mobility due to the misaligned bone structure.

Causes

The sequela arises from a prior displaced fracture of the first metatarsal bone in the left foot. The original injury likely resulted from direct trauma, such as a fall, sports injury, or high-impact event, which caused the bone fragments to shift out of position. Incomplete healing or inadequate realignment during initial treatment can lead to long-term consequences.

Risk Factors

• Previous history of foot fractures or injuries
• Inadequate initial fracture management or immobilization
• Conditions affecting bone healing, such as diabetes or poor circulation
• Advanced age, which may impair bone repair processes
• High-impact activities or occupations that stress the foot

Symptoms

• Chronic pain or discomfort in the left foot, particularly during weight-bearing
• Swelling or stiffness in the affected area
• Difficulty walking or altered gait due to misalignment
• Possible visible deformity or prominence over the fracture site
• Reduced range of motion in the big toe or midfoot

Diagnosis

A healthcare provider will evaluate the patient’s history of the original fracture and conduct a physical examination to assess alignment, pain, and functional limitations. Imaging studies, such as X-rays, may be used to confirm the displaced bone fragments and rule out new injuries. The diagnosis is based on the residual effects of the prior fracture, not an acute event.

Treatment Options

Treatment focuses on managing symptoms and improving function. Options may include orthotic devices or custom footwear to redistribute pressure, physical therapy to strengthen surrounding muscles, or analgesics for pain relief. In severe cases, surgical intervention to realign the bone may be considered, though this is less common for sequela.

Prognosis and Follow-Up

Prognosis depends on the severity of the displacement and the patient’s overall health. Many individuals experience improved function with conservative management, but some may have persistent limitations. Regular follow-up with a healthcare provider is recommended to monitor symptoms and adjust treatment as needed.

Complications

• Chronic pain or arthritis in the affected joint
• Persistent gait abnormalities or difficulty with weight-bearing
• Increased risk of future foot injuries due to altered biomechanics
• Nerve compression or irritation from misaligned bone fragments

Lifestyle & Prevention

• Wear supportive footwear to reduce stress on the foot
• Avoid high-impact activities that strain the foot
• Maintain a healthy weight to minimize pressure on the metatarsal
• Engage in exercises to strengthen foot and ankle muscles
• Follow up with a healthcare provider if symptoms worsen or new issues arise

When to Seek Professional Help

Seek medical attention if you experience increasing pain, swelling, or difficulty walking, or if you notice a new deformity in the left foot. These may indicate a new injury or worsening of the sequela.

Tips for Medical Coders

This code is used for a displaced fracture of the first metatarsal bone in the left foot, sequela. Document the history of the original fracture and the residual effects (e.g., chronic pain, gait changes) to support the sequela diagnosis. Ensure the code aligns with the patient’s current condition and prior injury documentation.
