S92.326A Nondisplaced fracture of second metatarsal bone, unspecified foot, initial encounter for closed fracture

Name of the Condition

• Technical Term: Nondisplaced fracture of second metatarsal bone, unspecified foot, initial encounter for closed fracture
• ICD-10 Code: S92.326A
• Common Name: Broken second metatarsal (unspecified foot), closed, initial encounter

Summary

A nondisplaced fracture of the second metatarsal bone in the unspecified foot is a break in the long bone of the midfoot where the bone fragments remain aligned. This injury typically results from trauma, such as a direct impact or twisting force, and is classified as closed (no open wound) during the initial encounter. The second metatarsal is a weight-bearing bone, making it susceptible to injury during activities that stress the foot. Treatment and recovery depend on the fracture's stability and the patient's overall health.

Causes

Direct trauma to the 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 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, specifically over the second metatarsal
• Swelling and bruising around the affected bone
• Difficulty bearing weight or walking on the injured foot
• Possible deformity if the fracture is severe (though nondisplaced fractures typically maintain alignment)

Diagnosis

Diagnosis involves a physical examination to assess pain, swelling, and mobility. Imaging studies, such as X-rays, are used to confirm the fracture and verify that the bone fragments are aligned (nondisplaced). Additional tests may be ordered if soft tissue damage or other injuries are suspected.

Treatment Options

Treatment focuses on immobilization, such as a cast or walking boot, to allow the bone to heal. Pain management with over-the-counter or prescription medications may be recommended. Physical therapy is often prescribed to restore strength and mobility once healing progresses. Severe cases may require surgical intervention, though nondisplaced fractures typically heal without surgery.

Prognosis and Follow-Up

Most nondisplaced fractures heal within 6–8 weeks with proper immobilization and rest. Follow-up appointments monitor healing through imaging and assess progress. Full recovery of strength and mobility may take several months, depending on the patient's activity level and adherence to treatment.

Complications

• Delayed healing or nonunion if the fracture is not properly immobilized
• Chronic pain or arthritis in the affected joint
• Nerve damage or soft tissue injury from the initial trauma
• Difficulty returning to high-impact activities without proper rehabilitation

Lifestyle & Prevention

• Wear supportive, properly 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 sports or high-risk activities

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). Follow up with a healthcare provider if pain persists or worsens after initial treatment.

Tips for Medical Coders

Document the encounter as "initial" for a closed, nondisplaced fracture of the second metatarsal in the unspecified foot. Ensure the record specifies the fracture type (nondisplaced) and absence of open wounds. Include details about the injury mechanism and any imaging results to support the diagnosis.
