S92.324B Nondisplaced fracture of second metatarsal bone, right foot, initial encounter for open fracture

Name of the Condition

• Technical Term: Nondisplaced fracture of second metatarsal bone, right foot, initial encounter for open fracture
• ICD-10 Code: S92.324B
• Common Name: Broken second metatarsal (right foot), open fracture

Summary

A nondisplaced fracture of the second metatarsal bone in the right foot is a break in the long bone of the midfoot where the bone fragments remain aligned. This injury is classified as an open fracture, meaning the skin over the fracture site is broken, increasing the risk of infection. The second metatarsal is a weight-bearing bone, and this type of fracture typically results from trauma, such as a direct impact or high-force injury. Treatment focuses on stabilizing the fracture and managing the open wound to prevent complications.

Causes

Direct trauma to the right foot, such as a fall, crush injury, or penetrating wound, is the most common cause. High-impact events, like motor vehicle accidents or sports-related injuries, can also lead to this type of fracture. Open fractures occur when the force of the injury breaks the skin, exposing the bone to the external environment.

Risk Factors

• Participation in high-impact sports or activities with a risk of foot trauma
• Wearing inadequate or non-protective footwear
• Conditions that weaken bones, such as osteoporosis or diabetes
• Advanced age, which may reduce bone density and increase fall risk
• Previous foot injuries or surgeries

Symptoms

• Severe pain and tenderness in the midfoot, specifically over the second metatarsal
• Visible wound or laceration at the fracture site
• Swelling, bruising, and possible bleeding from the open wound
• Difficulty bearing weight or walking on the injured foot
• Possible exposure of bone fragments through the skin

Diagnosis

Diagnosis involves a physical examination to assess the wound and fracture site, followed by imaging studies. X-rays are typically used to confirm the fracture and verify that it is nondisplaced. Additional tests, such as a CT scan, may be ordered to evaluate soft tissue damage or foreign bodies in the wound. The open nature of the fracture is assessed to determine the risk of infection.

Treatment Options

Treatment focuses on cleaning the wound to prevent infection, stabilizing the fracture, and promoting healing. This may include irrigation and debridement of the wound, followed by immobilization with a cast or splint. Antibiotics are often prescribed to reduce infection risk. In some cases, surgical intervention may be necessary to repair the fracture or close the wound.

Prognosis and Follow-Up

Prognosis depends on the severity of the open wound and the success of infection prevention. Most nondisplaced fractures heal well with proper immobilization and wound care. Follow-up appointments are necessary to monitor healing, remove sutures or hardware, and adjust treatment as needed. Physical therapy may be recommended to restore strength and mobility once the fracture has healed.

Complications

• Infection at the fracture site or wound
• Delayed healing due to open fracture exposure
• Nerve or blood vessel damage from the injury
• Chronic pain or arthritis in the midfoot
• Difficulty returning to normal activities or sports

Lifestyle & Prevention

• Wear protective footwear during high-risk activities
• Maintain bone health through a balanced diet and regular exercise
• Address underlying conditions that weaken bones, such as osteoporosis
• Use caution to avoid falls or direct trauma to the feet
• Seek prompt treatment for foot injuries to reduce complication risk

When to Seek Professional Help

Seek immediate medical attention if you experience a foot injury with an open wound, severe pain, or inability to bear weight. Signs of infection, such as increased redness, swelling, or pus, also require prompt evaluation. Delayed treatment may worsen outcomes for open fractures.

Tips for Medical Coders

Document the fracture as nondisplaced and specify the right foot and open fracture type. Include details about the initial encounter and any associated wound care. Ensure the open fracture is clearly documented to support the code, as this affects treatment and risk factors. Verify that the encounter is classified as initial to align with the code’s specificity.
