S92.311 Displaced fracture of first metatarsal bone, right foot

Name of the Condition

• Displaced fracture of first metatarsal bone, right foot
• ICD-10 Code: S92.311

Summary

This condition involves a break in the first metatarsal bone of the right foot, where the bone fragments are displaced from their normal alignment. The first metatarsal is the long bone connecting the big toe to the midfoot. Displacement occurs when the bone pieces shift out of position, often due to trauma. This is a localized injury affecting the right foot specifically.

Causes

Direct trauma or impact to the right foot is the primary cause. Common scenarios include dropping a heavy object, a sports injury (e.g., twisting the foot during activity), or a fall. High-force impacts can force the bone fragments out of alignment, leading to displacement.

Risk Factors

• Participation in high-impact sports (e.g., running, basketball)
• Wearing improper or non-supportive footwear
• Conditions that weaken bones, such as osteoporosis
• Previous foot injuries or fractures
• Advanced age, which may reduce bone density and balance

Symptoms

• Intense pain at the injury site
• Swelling and bruising around the right foot
• Difficulty bearing weight on the affected foot
• Possible visible deformity if the fracture is severely 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 determine the extent of displacement. Additional imaging (e.g., CT or MRI) may be ordered if the fracture is complex or involves soft tissue damage.

Treatment Options

• Immobilization with a cast or splint to stabilize the bone
• Pain management with over-the-counter or prescription medications
• Physical therapy to restore strength and mobility after healing
• Surgical intervention (e.g., internal fixation) for severe or unstable fractures

Prognosis and Follow-Up

Most displaced fractures of the first metatarsal heal within 6–8 weeks with proper immobilization. Follow-up appointments are necessary to monitor healing and adjust treatment. Full recovery depends on the severity of the fracture and adherence to rehabilitation protocols. Return to normal activities is gradual, with weight-bearing restrictions initially.

Complications

• Nonunion or delayed healing of the fracture
• Malunion (improper healing leading to deformity)
• Chronic pain or arthritis in the affected joint
• Nerve or soft tissue damage from the injury or surgery

Lifestyle & Prevention

• Wear supportive, properly fitting footwear during activities
• Use protective gear (e.g., orthotics) for high-impact sports
• Maintain bone health through a balanced diet and regular exercise
• Avoid sudden, forceful twisting or impacts to the foot

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, inability to bear weight, visible deformity, or signs of infection (e.g., redness, fever). Persistent pain or swelling after initial treatment also warrants evaluation.

Tips for Medical Coders

Document the specific location (right foot) and displacement status clearly. Ensure the fracture is confirmed as displaced, as this distinguishes it from non-displaced fractures. Include details about the encounter (e.g., initial, subsequent) and any treatment provided to support accurate coding.
