S92.323 Displaced fracture of second metatarsal bone, unspecified foot

Name of the Condition

• Technical Term: Displaced fracture of second metatarsal bone, unspecified foot
• ICD-10 Code: S92.323
• Common Name: Broken second metatarsal (unspecified foot)

Summary

A displaced fracture of the second metatarsal bone in an unspecified 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 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 affected foot
• Swelling and bruising around the affected bone
• Difficulty bearing weight or walking on the injured foot
• Possible deformity if the fracture is significantly displaced

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 or MRIs, may be ordered to assess soft tissue damage or complex fractures.

Treatment Options

Treatment depends on the severity of displacement and may include immobilization with a cast or boot, pain management, and activity modification. Surgical intervention may be necessary for severely displaced fractures to realign and stabilize the bone. Physical therapy is often recommended during recovery to restore strength and mobility.

Prognosis and Follow-Up

Most displaced fractures of the second metatarsal heal with proper treatment, though recovery time varies based on injury severity. Follow-up appointments are important to monitor healing and adjust treatment as needed. Long-term outcomes are generally favorable, but complications like arthritis or chronic pain may occur in some cases.

Complications

Potential complications include nonunion (failure to heal), malunion (improper healing), chronic pain, arthritis, or nerve damage. Infections may occur if surgery is required. Early intervention and adherence to treatment plans can reduce these risks.

Lifestyle & Prevention

Wearing supportive footwear, avoiding high-impact activities on unstable surfaces, and maintaining bone health through proper nutrition (e.g., calcium and vitamin D) can help prevent fractures. Gradual conditioning and proper technique in sports may also reduce injury risk.

When to Seek Professional Help

Seek medical attention if you experience severe foot pain, swelling, or inability to bear weight after an injury. Prompt evaluation is important for displaced fractures to ensure proper alignment and treatment, reducing the risk of complications.

Tips for Medical Coders

Use S92.323 for displaced fractures of the second metatarsal bone when the foot is unspecified. Document the absence of laterality (right/left) and confirm displacement status. Ensure clinical notes support the diagnosis and specify any associated injuries or treatments for accurate coding.
