S92.321 Displaced fracture of second metatarsal bone, right foot

Name of the Condition

• Technical Term: Displaced fracture of second metatarsal bone, right foot
• ICD-10 Code: S92.321
• Common Name: Broken second metatarsal, right foot

Summary

A displaced fracture of the second metatarsal bone in the right foot is a break in the long bone connecting the ankle to the toes, where the bone fragments are no longer aligned. This injury typically results from trauma, such as a direct impact or twisting force, and may affect mobility and weight-bearing ability. The severity and treatment depend on the extent of displacement and associated soft tissue damage.

Causes

Direct trauma to the right foot, such as a fall, sports injury, or dropping a heavy object, is the most common cause. Repetitive stress from activities like running or jumping can also lead to stress fractures over time. Twisting the foot or sudden impact may result in a displaced fracture, particularly in high-impact scenarios.

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 in the midfoot area of the right foot
• Swelling and bruising around the affected bone
• Difficulty bearing weight or walking on the right foot
• Visible deformity or abnormal positioning of the foot
• Possible numbness or tingling if nerves are affected

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 the degree of displacement. Additional scans, like CT or MRI, may be ordered if soft tissue damage or complex fractures are suspected.

Treatment Options

Treatment depends on the severity of displacement and may include immobilization with a cast or boot to allow healing. Surgical intervention may be necessary for severely displaced fractures to realign the bone. Pain management, physical therapy, and gradual weight-bearing as tolerated are common components of recovery.

Prognosis and Follow-Up

Most displaced fractures of the second metatarsal heal with proper treatment, though recovery time varies. Follow-up appointments are essential to monitor healing and adjust treatment plans. Complications, such as delayed union or arthritis, may occur but are less likely with appropriate care.

Complications

• Nonunion or delayed healing of the fracture
• Arthritis in the affected joint
• Chronic pain or stiffness
• Nerve damage leading to numbness or weakness
• Infection (if surgical intervention is required)

Lifestyle & Prevention

• Wear supportive, properly fitting footwear during activities.
• Avoid high-impact activities that stress the feet if at risk.
• Maintain bone health through a balanced diet and regular exercise.
• Use protective gear during sports to reduce injury risk.

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, fever) after an injury to the right foot.

Tips for Medical Coders

Document the specific location (right foot) and displacement status clearly in the medical record. Ensure the diagnosis supports the use of S92.321, as this code is specific to a displaced fracture of the second metatarsal bone in the right foot. Include details about the mechanism of injury and any imaging findings to justify the code selection.
