S92.322 Displaced fracture of second metatarsal bone, left foot

Name of the Condition

• Technical Term: Displaced fracture of second metatarsal bone, left foot
• ICD-10 Code: S92.322
• 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 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 left 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 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 the degree of 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. Severe cases may require surgical intervention to realign and stabilize the bone. Pain management and physical therapy are often part of the recovery process.

Prognosis and Follow-Up

Most displaced fractures heal with proper treatment, but recovery time varies based on the extent of injury. Follow-up appointments are necessary to monitor healing and adjust treatment as needed. Physical therapy may be recommended to restore strength and mobility.

Complications

Potential complications include nonunion (failure to heal), malunion (improper healing), chronic pain, or arthritis in the affected joint. Infection or nerve damage may occur if surgery is performed.

Lifestyle & Prevention

Wearing supportive footwear, avoiding high-impact activities on uneven surfaces, and maintaining bone health through proper nutrition can reduce risk. Strengthening foot and ankle muscles may also help prevent injuries.

When to Seek Professional Help

Seek medical attention if pain is severe, swelling worsens, or weight-bearing becomes impossible. Immediate care is needed if the foot appears deformed or if there are signs of infection, such as redness or fever.

Tips for Medical Coders

Document the laterality (left foot) and displacement status clearly. Ensure clinical notes specify the fracture type and any associated injuries. Use this code for initial encounters of closed displaced fractures; follow-up or subsequent encounters may require different codes.
