S92.324 Nondisplaced fracture of second metatarsal bone, right foot

Name of the Condition

• Technical Term: Nondisplaced fracture of second metatarsal bone, right foot
• ICD-10 Code: S92.324
• Common Name: Broken second metatarsal (right foot)

Summary

A nondisplaced fracture of the second metatarsal bone in the right foot is a break in the long bone connecting the ankle to the toes, where the bone fragments remain 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 the break and associated soft tissue damage.

Causes

Direct trauma to the right 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 nondisplaced 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 right foot
• Swelling and bruising around the affected bone
• Difficulty bearing weight or walking on the injured foot
• Possible deformity if the fracture is severe

Diagnosis

Diagnosis typically involves a physical examination to assess pain, swelling, and mobility. Imaging studies, such as X-rays, are used to confirm the fracture and determine if it is displaced. Additional tests, like CT scans or MRIs, may be ordered if soft tissue damage or other injuries are suspected.

Treatment Options

Treatment may include rest, ice, compression, and elevation (RICE) to reduce swelling. Immobilization with a cast or boot is often recommended to protect the bone during healing. Pain management with over-the-counter or prescription medications may be necessary. Physical therapy can help restore strength and mobility once the fracture has healed.

Prognosis and Follow-Up

Most nondisplaced fractures heal within 6-8 weeks with proper immobilization and rest. Follow-up appointments are important to monitor healing and adjust treatment as needed. Full recovery depends on the severity of the fracture and adherence to recommended care.

Complications

Potential complications include delayed healing, nonunion (failure to heal), or malunion (improper healing). Infection or nerve damage may occur if the fracture is open or associated with soft tissue injury. Chronic pain or arthritis in the foot may develop in some cases.

Lifestyle & Prevention

Wearing supportive footwear and using proper techniques during sports or physical activities can reduce the risk of injury. Maintaining bone health through a balanced diet and regular exercise may also help prevent fractures. Avoiding high-impact activities on uneven surfaces can further minimize risk.

When to Seek Professional Help

Seek medical attention if pain is severe, swelling worsens, or mobility is significantly impaired. Immediate care is needed if the foot appears deformed, or if there are signs of infection, such as redness, warmth, or pus.

Tips for Medical Coders

Document the location (right foot) and fracture type (nondisplaced) clearly in the medical record. Ensure the code S92.324 is used when the fracture is confirmed as nondisplaced and limited to the second metatarsal bone of the right foot. Include details about trauma mechanism or associated injuries if relevant for accurate coding.
