S92.33 Fracture of third metatarsal bone

Name of the Condition

• Fracture of third metatarsal bone.

Summary

A fracture of the third metatarsal bone is a break in the long bone connecting the ankle to the toes, specifically the third metatarsal. This injury typically results from trauma or repetitive stress and may vary in severity, including displaced or nondisplaced fractures.

Causes

Direct trauma to the foot, such as a heavy object falling or a twisting injury, is a 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., basketball, soccer)
• Wearing improper or non-supportive footwear
• Conditions that weaken bones, such as osteoporosis
• Advanced age, which may reduce bone density
• Previous foot injuries or fractures

Symptoms

• Pain and tenderness in the midfoot area
• Swelling and bruising around the affected bone
• Difficulty bearing weight or walking
• Possible deformity if the fracture is 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 determine its extent.

Treatment Options

• Rest and immobilization, often using a cast or walking boot, to allow healing
• Over-the-counter pain relievers such as acetaminophen or ibuprofen to manage pain
• Physical therapy might be recommended after the bone has healed to restore strength and mobility

Prognosis and Follow-Up

Most fractures of the third metatarsal heal well with proper treatment. Follow-up care may include monitoring for healing progress and adjusting treatment as needed. Return to normal activities depends on the severity of the fracture and adherence to recovery guidelines.

Complications

• Delayed healing or nonunion of the fracture
• Infection, particularly if the fracture is open (skin is broken)
• Chronic pain or arthritis in the affected area
• Nerve damage or altered sensation

Lifestyle & Prevention

• Wear supportive, properly fitting footwear during activities
• Gradually increase activity intensity to avoid overuse injuries
• Maintain bone health through a balanced diet and regular exercise
• Use protective gear during high-impact sports

When to Seek Professional Help

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

Tips for Medical Coders

Document the specific location (third metatarsal) and any details about the fracture (e.g., displaced, nondisplaced) to ensure accurate coding. Include clinical notes on the mechanism of injury and treatment provided to support the code selection.
