Is surgery necessary for a fifth metatarsal fracture with a wide gap and slow bone healing?


On November 8, 2020, I sustained a fracture of the fifth metatarsal.
The doctor recommended either a cast or a brace, and I chose to wear a brace (similar to a walking boot with a raised sole).
Due to the height difference between my feet, I have been using a four-legged cane for assistance.
I return for follow-up appointments and X-rays every four weeks.
As a patient with bone metastasis, I receive Xgeva injections monthly, and my bone growth is extremely slow.
Additionally, I am supplementing with amorphous calcium.

The fracture site is somewhat wide, and I have been wearing the brace for approximately 13 weeks.
The width of the fracture has only developed fine lines.
The physicians at my workplace have suggested that I should undergo minimally invasive titanium fixation, as relying solely on the brace makes it extremely difficult for the wide fracture to heal properly.
Since I am being treated at another facility, my next appointment is scheduled for seven weeks from now (at which point the fracture will be 20 weeks old).
I am unsure of what to do next.
I can provide my health record and X-ray images, but I cannot attach files here.
What should I do?

Patients receiving Xgeva may experience delayed bone healing; however, percutaneous minimally invasive nailing can accelerate the healing process with relatively low risk.

When considering surgery for slow-healing fifth metatarsal fractures, there are several factors to take into account. The fifth metatarsal, located on the outer side of the foot, is a common site for fractures, especially in athletes or individuals who engage in high-impact activities. However, fractures in this area can sometimes heal slowly, particularly in patients with underlying conditions that affect bone healing, such as osteoporosis or those undergoing treatments like Xgeva (denosumab), which is used to prevent skeletal-related events in patients with bone metastases.


Factors to Consider for Surgery
1. Healing Progress: Given that you have been using a protective boot for approximately 13 weeks and have seen minimal improvement in the fracture site, it is crucial to evaluate the healing process. The presence of a wide fracture gap that has only shown minor signs of healing (thin lines) suggests that conservative treatment may not be sufficient.

2. Underlying Conditions: Your history of bone metastasis and the use of Xgeva indicate that your bone healing capacity may be compromised. This is an important consideration, as it may affect both the healing time and the effectiveness of surgical intervention.

3. Surgical Options: The suggestion of minimally invasive titanium fixation could be beneficial. This procedure typically involves the insertion of screws or plates to stabilize the fracture, which can promote better alignment and healing. The advantage of surgical intervention is that it may provide a more immediate solution to the problem of non-union or delayed healing.

4. Risks and Benefits: Surgery carries risks, including infection, nerve damage, and complications related to anesthesia. However, the potential benefits—such as improved healing rates and reduced pain—may outweigh these risks, especially if conservative management has not yielded results.

5. Consultation with Specialists: Since you are currently seeing a physician at a different facility, it is advisable to communicate your concerns and the recommendations from your current healthcare provider. You can request a referral to an orthopedic surgeon who specializes in foot and ankle injuries. They can provide a thorough evaluation and discuss the potential for surgical intervention.

6. Timing of Surgery: If surgery is deemed necessary, it is generally recommended to proceed sooner rather than later, particularly if the fracture has not shown significant improvement after 20 weeks. Delaying surgery can lead to further complications, such as chronic pain or instability in the foot.


Next Steps
- Follow-Up Appointment: Ensure that you attend your next follow-up appointment in 7 weeks. Bring any imaging studies or health records that can provide your new physician with a comprehensive view of your condition.

- Prepare Questions: Before your appointment, prepare a list of questions regarding the surgical procedure, recovery time, rehabilitation, and any potential risks involved. This will help you make an informed decision.

- Consider a Second Opinion: If you feel uncertain about the recommendations from your current physician, seeking a second opinion from another orthopedic specialist can provide additional insights and options.

In conclusion, while conservative management is often the first line of treatment for fifth metatarsal fractures, your specific circumstances—particularly the slow healing and underlying health conditions—may warrant consideration of surgical options. Engaging in open discussions with your healthcare providers will be crucial in determining the best course of action for your recovery.
