S92.314 Nondisplaced fracture of first metatarsal bone, right foot

Name of the Condition

• Nondisplaced fracture of first metatarsal bone, right foot
• ICD-10 Code: S92.314

Summary

A nondisplaced fracture of the first metatarsal bone in the right foot is a break where the bone fragments remain in their normal alignment. The first metatarsal is the long bone connecting the big toe to the midfoot and is a primary weight-bearing structure. This type of fracture typically results from trauma, such as a direct impact or twisting force, and does not involve displacement of the bone fragments. The injury is localized to the right foot and may affect mobility and stability.

Causes

Direct trauma to the right foot is the most common cause. This can include dropping a heavy object, a sports injury (e.g., twisting the foot during activity), or a fall. High-force impacts may lead to a fracture, while repetitive stress from activities like running or jumping can result in stress fractures over time. The bone remains intact in alignment, distinguishing it from displaced fractures.

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 at the base of the big toe (right foot)
• Swelling and bruising around the affected area
• Difficulty bearing weight or walking on the injured foot
• Possible mild deformity, though less common than with displaced fractures

Diagnosis

A healthcare provider will perform a physical examination to assess pain, swelling, and range of motion. Imaging studies, such as X-rays, are typically used to confirm the fracture and verify that it is nondisplaced. The provider may also evaluate the foot’s alignment and check for associated injuries.

Treatment Options

Treatment focuses on immobilization to allow healing, such as a cast, boot, or splint. Rest, ice, and elevation may help reduce swelling and pain. Nonsteroidal anti-inflammatory drugs (NSAIDs) can manage discomfort. Weight-bearing may be restricted initially, with gradual return to normal activity as healing progresses. Physical therapy may be recommended to restore strength and mobility.

Prognosis and Follow-Up

Most nondisplaced fractures heal well with proper immobilization and rest. Full recovery typically occurs within 6–8 weeks, though this may vary based on the individual’s health and activity level. Follow-up appointments are important to monitor healing and adjust treatment as needed. Return to high-impact activities should be gradual to avoid re-injury.

Complications

While rare, complications can include delayed healing, nonunion (failure to heal), or infection if the skin is broken. Chronic pain or arthritis may develop in severe cases, though this is less likely with nondisplaced fractures. Nerve or soft tissue damage is also possible but uncommon.

Lifestyle & Prevention

Wearing supportive footwear during activities can reduce injury risk. Avoiding repetitive high-impact stress and maintaining bone health through a balanced diet and exercise may help prevent fractures. Strengthening foot and ankle muscles can improve stability and reduce the likelihood of trauma.

When to Seek Professional Help

Seek medical attention if pain is severe, swelling worsens, or weight-bearing becomes impossible. Signs of infection (e.g., redness, pus) or persistent numbness require prompt evaluation. If the foot appears deformed or symptoms do not improve with rest, consult a healthcare provider.

Tips for Medical Coders

Document the fracture as nondisplaced and specify the right foot. Include details on the mechanism of injury (e.g., trauma, stress) and any imaging results confirming the diagnosis. Ensure the code S92.314 is used for nondisplaced fractures of the first metatarsal bone in the right foot, distinguishing it from displaced or bilateral cases.
