S92.322A Displaced fracture of second metatarsal bone, left foot, initial encounter for closed fracture

Name of the Condition

• Technical Term: Displaced fracture of second metatarsal bone, left foot, initial encounter for closed fracture
• ICD-10 Code: S92.322A
• Common Name: Broken second metatarsal (left foot)

Summary

A displaced fracture of the second metatarsal bone in the left foot is a break in the long bone connecting the ankle to the toes, where the bone fragments are out of alignment. This injury occurs during the initial encounter for a closed fracture, meaning the skin is intact and no surgical intervention has been performed yet. The second metatarsal is a weight-bearing bone, and displacement may affect mobility and healing.

Causes

Direct trauma to the left foot, such as a fall, sports injury, or heavy object impact, is the primary cause. Twisting forces or repetitive stress from activities like running may also lead to this type of fracture. The displacement occurs when the bone breaks and shifts out of its normal position.

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 (left foot)
• Swelling and bruising around the affected bone
• Difficulty bearing weight or walking on the injured foot
• Possible deformity if displacement is severe

Diagnosis

Diagnosis typically involves a physical examination to assess pain, swelling, and deformity. Imaging studies, such as X-rays, are used to confirm the fracture and evaluate displacement. Additional tests, like CT scans, may be ordered if detailed visualization of the fracture pattern is needed.

Treatment Options

Treatment depends on the severity of displacement and may include immobilization with a cast or boot to allow healing. Pain management with medications or ice may be recommended. Severe cases may require realignment (reduction) or surgical intervention to restore proper bone alignment.

Prognosis and Follow-Up

Most displaced fractures heal with proper immobilization and rest, though recovery time varies. Follow-up appointments monitor healing progress, and physical therapy may be recommended to restore strength and mobility. Long-term outcomes depend on the extent of displacement and adherence to treatment.

Complications

Potential complications include nonunion (failure to heal), malunion (improper healing), chronic pain, or arthritis in the affected joint. Infection risk is low for closed fractures but may increase with surgical intervention.

Lifestyle & Prevention

Wearing supportive footwear, avoiding high-impact activities on unstable surfaces, and maintaining bone health through diet and exercise can reduce fracture risk. Gradual return to activity after injury is important to prevent re-injury.

When to Seek Professional Help

Seek immediate medical attention for severe pain, inability to bear weight, visible deformity, or signs of infection (e.g., redness, pus). Persistent pain or swelling after initial treatment also warrants evaluation.

Tips for Medical Coders

Document the laterality (left foot), displacement status, and encounter type (initial for closed fracture) to accurately assign S92.322A. Ensure clinical notes specify the fracture as closed and the encounter as initial to meet coding guidelines.
