S92.352S Displaced fracture of fifth metatarsal bone, left foot, sequela

Name of the Condition

• Technical Term: Displaced fracture of fifth metatarsal bone, left foot, sequela
• ICD-10 Code: S92.352S
• Common Name: Healed displaced fifth metatarsal fracture (left foot, with residual effects)

Summary

A displaced fracture of the fifth metatarsal bone in the left foot, sequela, refers to the residual effects or complications that persist after the initial fracture has healed. This condition occurs when the bone fragments, previously displaced, have healed in a non-anatomical position, leading to ongoing functional or structural issues. The fifth metatarsal is the long bone on the outer edge of the foot, and malunion or persistent displacement can affect stability, gait, and overall foot function.

Causes

The sequela arises from a prior displaced fracture of the fifth metatarsal bone in the left foot. The initial injury may have resulted from trauma, repetitive stress, or other mechanisms, and the residual effects are a consequence of the healing process, such as malunion, nonunion, or persistent instability.

Risk Factors

• Inadequate initial treatment or immobilization of the original fracture
• High-impact activities or sports that stress the foot
• Underlying conditions affecting bone healing (e.g., diabetes, poor circulation)
• Advanced age, which may impair bone remodeling
• Previous foot injuries or fractures in the same area

Symptoms

• Chronic pain or discomfort on the outer edge of the left foot
• Swelling or stiffness in the affected area
• Difficulty bearing weight or altered gait
• Possible deformity or prominence of the fifth metatarsal
• Reduced range of motion in the foot or ankle

Diagnosis

Diagnosis involves a clinical evaluation, including a review of the patient’s history of the initial fracture and current symptoms. Physical examination assesses for tenderness, deformity, or instability. Imaging studies, such as X-rays or CT scans, may be used to evaluate the healed fracture site and identify residual displacement, malunion, or associated complications.

Treatment Options

Treatment focuses on managing symptoms and improving function. Options may include:

• Orthotic devices or supportive footwear to stabilize the foot
• Physical therapy to strengthen surrounding muscles and improve mobility
• Pain management with medications or injections
• Surgical intervention in severe cases to correct malunion or address persistent instability

Prognosis and Follow-Up

Prognosis depends on the extent of residual displacement and the patient’s response to treatment. Most patients experience improved function with appropriate management, though some may have long-term limitations. Regular follow-up with a healthcare provider is important to monitor healing and adjust treatment as needed.

Complications

• Chronic pain or discomfort
• Altered gait or increased risk of falls
• Development of arthritis in the affected joint
• Persistent instability or weakness in the foot
• Need for additional interventions if symptoms worsen

Lifestyle & Prevention

• Wear supportive, well-fitted footwear to reduce stress on the foot
• Avoid high-impact activities that may exacerbate symptoms
• Engage in low-impact exercises (e.g., swimming, cycling) to maintain fitness
• Maintain a healthy weight to reduce foot strain
• Follow post-treatment recommendations to optimize healing and function

When to Seek Professional Help

Seek medical attention if you experience:

• Worsening pain or swelling
• New deformity or changes in foot shape
• Difficulty walking or bearing weight
• Signs of infection (e.g., redness, warmth, drainage)
• Persistent symptoms that interfere with daily activities

Tips for Medical Coders

This code (S92.352S) is used for the sequela of a displaced fracture of the fifth metatarsal bone in the left foot. Documentation should clearly indicate the residual effects or complications following the initial fracture, such as malunion, chronic pain, or functional impairment. Ensure the code aligns with the patient’s current condition and that the sequela is directly attributable to the prior fracture.
