S92.341 Displaced fracture of fourth metatarsal bone, right foot

Name of the Condition

• Displaced fracture of fourth metatarsal bone, right foot
• ICD-10 code: S92.341

Summary

A displaced fracture of the fourth metatarsal bone in the right foot is a break in the long bone connecting the ankle to the toes, where the bone fragments have shifted out of their normal alignment. This type of injury typically results from trauma or repetitive stress and requires evaluation to determine the extent of displacement and appropriate management.

Causes

Direct trauma to the foot, such as a fall, impact during sports, or a heavy object dropped on the foot, is the most common cause. Repetitive stress from activities like running or jumping can also lead to stress fractures over time.

Risk Factors

• Participation in high-impact sports (e.g., soccer, basketball)
• 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 localized to the outer midfoot
• Swelling and bruising around the affected area
• Difficulty bearing weight or walking on the right foot
• Possible visible 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. In some cases, additional imaging like an MRI may be ordered to assess soft tissue damage.

Treatment Options

• Immobilization with a cast, boot, or brace to maintain alignment and promote healing
• Limited weight-bearing activities to reduce stress on the fracture
• Pain management with NSAIDs or acetaminophen
• Surgical intervention may be required for severe displacement or unstable fractures

Prognosis and Follow-Up

Most displaced fractures of the fourth metatarsal bone heal well with proper treatment, though recovery time may vary. Follow-up care typically includes periodic imaging to monitor healing and gradual return to weight-bearing activities. Physical therapy may be recommended to restore strength and mobility.

Complications

• Nonunion or delayed healing of the fracture
• Malunion, where the bone heals in an abnormal position
• Chronic pain or arthritis in the affected area
• Nerve or soft tissue damage from the injury or treatment

Lifestyle & Prevention

• Wear supportive, well-fitting footwear during activities
• Gradually increase activity intensity to avoid overuse injuries
• Maintain bone health through a balanced diet rich in calcium and vitamin D
• Use protective gear during high-impact sports

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, inability to bear weight, visible deformity, or signs of infection (e.g., redness, warmth, fever) after an injury to the right foot.

Tips for Medical Coders

Document the specific location (right foot) and the displaced nature of the fracture to support the use of code S92.341. Include details about the mechanism of injury, imaging findings, and treatment provided to ensure accurate coding and clinical correlation.
