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

Name of the Condition

• Technical Term: Displaced fracture of fifth metatarsal bone, left foot
• ICD-10 Code: S92.352
• Common Name: Broken fifth metatarsal (left foot)

Summary

A displaced fracture of the fifth metatarsal bone in the left foot occurs when the bone breaks and the fragments shift out of their normal alignment. This injury typically results from trauma or repetitive stress and requires medical evaluation to assess the extent of displacement and guide treatment. The fifth metatarsal is the long bone on the outer edge of the foot, and displacement can affect stability and healing.

Causes

Direct trauma to the foot, such as a fall, twist, or impact, is the primary cause. Sports injuries, missteps, or accidents involving the foot are common triggers. Repetitive stress from activities like running or jumping may also lead to fractures over time.

Risk Factors

• Participation in high-impact sports (e.g., basketball, soccer)
• Wearing improper or non-supportive footwear
• Conditions that weaken bones, such as osteoporosis
• Advanced age, which may reduce bone density and balance
• Previous foot injuries or fractures

Symptoms

• Pain and tenderness on the outer edge of the left foot
• Swelling or bruising in the affected area
• Difficulty bearing weight on the left foot
• Possible deformity if the fracture is severely displaced

Diagnosis

A healthcare provider will perform a physical examination to assess pain, swelling, and range of motion. Imaging tests, such as X-rays, are typically used to confirm the fracture and evaluate the degree of displacement. Additional imaging, like CT scans, may be ordered if more detailed visualization is needed.

Treatment Options

• Immobilization with a cast or boot to allow healing
• Pain management with medications or ice
• Physical therapy to restore strength and mobility
• Surgical intervention for severe displacement or unstable fractures
• Weight-bearing restrictions as advised by a provider

Prognosis and Follow-Up

Most displaced fractures heal with proper treatment, but recovery time varies based on severity and alignment. Follow-up appointments are necessary to monitor healing and adjust treatment. Complications like nonunion or malunion may require additional intervention.

Complications

• Delayed healing or nonunion of the fracture
• Malunion, where the bone heals in an incorrect position
• Chronic pain or arthritis in the foot
• Nerve or tissue damage from the injury or treatment

Lifestyle & Prevention

• Wear supportive footwear during activities
• Gradually increase activity intensity to avoid overuse
• Maintain bone health with proper nutrition (e.g., calcium, vitamin D)
• Use protective gear in high-risk sports
• Address foot pain promptly to prevent further injury

When to Seek Professional Help

Seek immediate care if you experience severe pain, inability to bear weight, visible deformity, or signs of infection (e.g., redness, fever). Persistent pain or swelling after initial treatment also warrants evaluation.

Tips for Medical Coders

Document the laterality (left foot) and displacement status clearly. Include details on fracture type (e.g., transverse, oblique) and treatment approach if available. Ensure alignment with clinical notes to support code specificity.
