Displaced fifth metatarsal fracture and the use of a brace?


Hello Doctor, I suffered a fifth metatarsal fracture from a fall on March 2nd.
I started wearing the recommended protective shoe on March 4th after switching from a cast.
However, during my follow-up appointment in the second week, it was found that the fracture gap had increased (the first image is from March 2nd when I was first injured, and the second image is from my follow-up on March 16th).
I usually only remove the protective shoe while showering and continue to wear it while sleeping, but there have been a few nights when I woke up in pain due to pressure on the bone from turning in my sleep.
I'm not sure if this has contributed to the increased fracture gap.

I would like to ask the doctor:
1.
While using the protective shoe, is it completely necessary to avoid putting weight on the foot? I was originally supposed to travel abroad after one week, and the doctor said I could walk in the protective shoe if I didn't go.
I immediately canceled my trip and have been at home for the past three weeks, using a single crutch to walk slowly, which doesn't cause much pain.

2.
Is it normal to experience pain from the pressure of the protective shoe on the bone while sleeping? Is it due to poor foot positioning, or should I remove it while sleeping?
3.
The doctor suggested surgery, but is it possible to continue with conservative treatment (as I really prefer to avoid surgery)?

Conservative treatment can continue, but if healing does not occur, surgery will be necessary.

Managing displaced fifth metatarsal fractures can be challenging, especially when it comes to brace use and recovery. Based on your situation, here are some insights and recommendations.

1. Brace Use and Weight Bearing: When dealing with a fifth metatarsal fracture, especially if it is displaced, the use of a protective shoe or brace is crucial. Generally, the recommendation is to avoid putting weight on the injured foot for a certain period, typically 4-6 weeks, depending on the severity of the fracture and the healing progress. Since you are in the third week of recovery and have been using crutches to walk, this is a good approach. If your doctor has advised that you can walk in the brace, it is essential to do so cautiously. However, if you experience pain while walking, it may indicate that you are putting too much stress on the fracture site. Always follow your doctor's specific instructions regarding weight-bearing activities.

2. Pain During Sleep: Experiencing pain while wearing the protective shoe at night is not uncommon, especially if the shoe is too tight or if your foot is in an awkward position. It might be beneficial to remove the shoe while sleeping if you feel that it causes discomfort. However, ensure that your foot is elevated and well-supported to avoid swelling. If you choose to keep the shoe on, consider adjusting its fit or using padding to alleviate pressure points. If the pain persists or worsens, consult your doctor for further evaluation.

3. Surgical vs. Conservative Treatment: The decision to proceed with surgery versus conservative management depends on several factors, including the degree of displacement, your overall health, activity level, and how well the fracture is healing. If your doctor has suggested surgery, it may be because they believe that the fracture will not heal properly without intervention. However, if you prefer to continue with conservative treatment, discuss this with your doctor. They may be able to provide a more tailored recovery plan that includes regular follow-ups and imaging to monitor healing progress.
In addition to these points, here are some general tips for recovery:
- Rest and Elevation: Ensure you are resting your foot as much as possible and keeping it elevated to reduce swelling. This is particularly important in the early stages of recovery.


- Ice Therapy: Applying ice to the affected area can help manage pain and swelling. Use ice packs for 15-20 minutes several times a day, especially after any activity.

- Physical Therapy: Once your doctor gives the green light, consider starting physical therapy to regain strength and mobility in your foot. A physical therapist can provide exercises tailored to your recovery stage.

- Nutrition: Ensure you are consuming a balanced diet rich in calcium and vitamin D to support bone healing. Foods like dairy products, leafy greens, and fortified foods can be beneficial.

- Follow-Up Appointments: Keep all follow-up appointments with your doctor to monitor the healing process. Regular X-rays may be necessary to assess the fracture's status.

In conclusion, managing a displaced fifth metatarsal fracture requires careful attention to brace use, pain management, and monitoring healing progress. Open communication with your healthcare provider is essential to ensure the best recovery outcome. If you have any concerns about your treatment plan or experience increased pain or complications, do not hesitate to reach out to your doctor for guidance.
