Fractures of the first metatarsal bone, classified under ICD-10 code S92.31, are common injuries that can significantly impact mobility and quality of life. The treatment approach for these fractures typically depends on the severity of the fracture, the patient's overall health, and their activity level. Below is a detailed overview of standard treatment approaches for this type of fracture.

Initial Assessment and Diagnosis

Before treatment can begin, a thorough assessment is essential. This typically includes:

• Clinical Examination: Assessing the foot for swelling, bruising, and deformity.
• Imaging Studies: X-rays are the primary imaging modality used to confirm the fracture and assess its type (e.g., non-displaced, displaced, or comminuted) and any associated injuries.

Treatment Approaches

Conservative Management

For non-displaced fractures or those with minimal displacement, conservative management is often sufficient. This may include:

• Rest and Immobilization: Patients are advised to rest the affected foot and avoid weight-bearing activities. Immobilization can be achieved using:
• Walking Boots: A stiff-soled boot can provide support and limit movement.

• Cast: In some cases, a short leg cast may be applied for additional stability.

• Weight-Bearing Protocol: Gradual weight-bearing is encouraged as healing progresses. Early mobilization can be beneficial, but it should be guided by pain levels and clinical judgment[1][2].

• Pain Management: Non-steroidal anti-inflammatory drugs (NSAIDs) can be prescribed to manage pain and inflammation.

Surgical Intervention

Surgical treatment may be necessary for more severe fractures, particularly those that are displaced or involve joint surfaces. Surgical options include:

• Open Reduction and Internal Fixation (ORIF): This procedure involves realigning the fractured bone fragments and securing them with plates and screws. ORIF is often indicated for displaced fractures to restore proper alignment and function[3].

• Percutaneous Fixation: In some cases, minimally invasive techniques may be used to stabilize the fracture without extensive surgical exposure.

Rehabilitation

Post-treatment rehabilitation is crucial for restoring function and strength. This may involve:

• Physical Therapy: A structured rehabilitation program can help improve range of motion, strength, and balance. Therapy often begins with gentle exercises and progresses to more demanding activities as healing allows.

• Gradual Return to Activity: Patients are typically advised to gradually return to their normal activities, including sports, once they have regained sufficient strength and mobility.

Complications and Follow-Up

Regular follow-up appointments are essential to monitor healing and detect any complications, such as:

• Nonunion or Malunion: Inadequate healing can lead to persistent pain and functional limitations. Surgical intervention may be required to correct these issues[4].

• Post-Traumatic Arthritis: Damage to the joint surfaces can lead to arthritis, necessitating further treatment.

Conclusion

The treatment of first metatarsal fractures (ICD-10 code S92.31) typically involves a combination of conservative management and surgical intervention, depending on the fracture's characteristics. Early diagnosis, appropriate treatment, and diligent rehabilitation are key to ensuring optimal recovery and minimizing complications. Patients should work closely with their healthcare providers to develop a tailored treatment plan that addresses their specific needs and activity levels.
