S92.325 Nondisplaced fracture of second metatarsal bone, left foot

Name of the Condition

• Technical Term: Nondisplaced fracture of second metatarsal bone, left foot
• ICD-10 Code: S92.325
• Common Name: Broken second metatarsal (left foot)

Summary

A nondisplaced 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 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 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 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 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 more detailed bone structure is suspected.

Treatment Options

Treatment depends on the severity of the fracture. Nondisplaced fractures often require immobilization with a cast or walking boot to allow healing. Pain management may include over-the-counter or prescription medications. Physical therapy is recommended to restore strength and mobility once the fracture heals.

Prognosis and Follow-Up

Most nondisplaced fractures heal within 6–8 weeks with proper immobilization and care. Follow-up appointments are necessary to monitor healing and adjust treatment as needed. Full recovery of strength and function is expected, but activity restrictions may be advised during the healing period.

Complications

Complications are rare but may include delayed healing, nonunion, or malunion of the bone. Infection or nerve damage can occur if the fracture is open or associated with significant soft tissue injury. Chronic pain or arthritis may develop in severe cases.

Lifestyle & Prevention

Wearing supportive footwear and avoiding high-impact activities can reduce fracture risk. Strengthening foot and ankle muscles through exercise may improve stability. Maintaining bone health with a balanced diet and regular check-ups is also beneficial.

When to Seek Professional Help

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

Tips for Medical Coders

Document the location (left foot) and fracture type (nondisplaced) clearly in the medical record. Ensure the diagnosis aligns with clinical findings and imaging results. Code S92.325 is specific to the left foot; verify laterality and displacement status to avoid miscoding.
