S92.32 Fracture of second metatarsal bone

Name of the Condition

• Technical Term: Fracture of second metatarsal bone
• ICD-10 Code: S92.32
• Common Name: Broken second metatarsal

Summary

A fracture of the second metatarsal bone is a break in the long bone located in the midfoot, between the ankle and the toes. This injury typically results from trauma, such as a direct impact or twisting force, and can vary in severity depending on the extent of the break. The second metatarsal is a weight-bearing bone, making it susceptible to injury during activities that stress the foot.

Causes

Direct trauma to the foot, such as dropping a heavy object, a sports injury, or a fall, 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 displaced

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 rule out other injuries. In some cases, additional imaging like CT or MRI may be ordered to evaluate the extent of the injury.

Treatment Options

Treatment depends on the severity of the fracture. Minor fractures may be managed with rest, ice, compression, and elevation (RICE), along with immobilization using a cast or boot. Severe or displaced fractures may require surgical intervention to realign the bone. Pain management and physical therapy are often part of the recovery process.

Prognosis and Follow-Up

Most fractures of the second metatarsal heal well with appropriate treatment, though recovery time varies based on the severity. Follow-up appointments are important 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. Infections may occur if surgery is performed. Nerve or blood vessel damage is rare but possible with severe trauma.

Lifestyle & Prevention

Wearing supportive footwear, especially during high-impact activities, can reduce risk. Gradually increasing activity levels and avoiding overuse may prevent stress fractures. Maintaining bone health through a balanced diet and regular exercise can also help.

When to Seek Professional Help

Seek medical attention if you experience severe pain, swelling, or difficulty walking after an injury. Immediate care is needed if the foot appears deformed, or if there is numbness, tingling, or coldness in the toes, which may indicate nerve or blood vessel damage.

Tips for Medical Coders

Document the specific metatarsal involved (second) and the fracture type (e.g., displaced, nondisplaced) to support accurate coding. Ensure clinical documentation aligns with the ICD-10-CM code S92.32, as specificity is required for this code. Include details about the mechanism of injury and any imaging results to justify the diagnosis.
