Healing Time for Non-Displaced Fibula Fractures: What to Expect - Orthopedics

How long does it take for a non-displaced closed fracture of the right fibula's lateral malleolus to heal?


I had a fall due to a non-collision accident on May 14th, and I was hospitalized for 7 days.
The doctor diagnosed me with a non-displaced closed fracture of the right fibula at the lateral malleolus on the same day.
Surgery was not required, and I am undergoing conservative treatment.
After discharge, I have been using a lightweight cast for support.
It has now been three weeks, and I had my second follow-up appointment on June 4th.
After the second X-ray, the results showed little change compared to the last one.
I would like to ask the following three questions:
1.
Does this indicate that my healing process is not progressing well?
2.
While wearing the lightweight cast, if I accidentally bump it lightly, could that affect the fracture's alignment or cause it to crack? (I am concerned about displacement since I did not have surgical fixation.)
3.
How long does it typically take for this type of fracture to start forming new bone and allow weight-bearing?
I have attached a link to some photos for your review: https://imgur.com/gallery/Icj7eCE.
Thank you, doctor!

Fractures generally require a recovery period of about three months, but this can vary depending on the individual's condition and healing process.
Please follow your physician's advice for treatment and follow-up appointments.
If you have any concerns, it is advisable to discuss them with your attending physician.
Thank you.

Healing from a non-displaced fibula fracture, such as the one you've described, typically follows a predictable timeline, but individual recovery can vary based on several factors, including age, overall health, and adherence to rehabilitation protocols.
1. Healing Status: The fact that your X-rays have shown little change after two weeks may raise concerns, but it is important to remember that non-displaced fractures often heal slower than displaced ones. The healing process involves the formation of a callus around the fracture site, which may not be immediately visible on X-rays. In general, non-displaced fibula fractures can take anywhere from 6 to 8 weeks to heal sufficiently for weight-bearing activities, but this can vary. If your doctor has not expressed concern about your healing progress, it may be that your body is simply taking its time to heal.

2. Impact of Minor Trauma: Wearing a lightweight cast provides some protection, but it is still crucial to be cautious. Minor bumps or impacts are unlikely to cause significant displacement in a non-displaced fracture, especially if you are following your doctor's advice regarding activity levels. However, it is advisable to avoid any activities that could lead to falls or additional trauma to the area. If you do experience a significant impact or if you notice increased pain or swelling, it would be wise to consult your healthcare provider for further evaluation.

3. Timeline for Weight-Bearing: Generally, you can expect to start bearing weight on the affected leg around 6 to 8 weeks post-injury, depending on your healing progress. Your doctor will likely assess your X-rays and your ability to tolerate weight on the leg before giving you the green light to start walking without assistance. It is common to use crutches or a walker during the initial stages of recovery to prevent undue stress on the healing bone.
In terms of rehabilitation, physical therapy may be recommended to help restore strength and mobility once your doctor clears you for weight-bearing activities. This typically includes exercises to improve range of motion, strength training, and balance exercises to prevent future injuries.

In summary, while it can be concerning to see little change in your X-rays after a couple of weeks, it is not uncommon for non-displaced fractures. Continue to follow your doctor's recommendations, and be patient with your recovery process. If you have any concerns about your healing or experience any unusual symptoms, do not hesitate to reach out to your healthcare provider for guidance.

Dr. Shi Guozheng reply Orthopedics
Typically, if a fibular fracture at the ankle joint is non-displaced, surgery may not be necessary. A cast immobilization for about eight weeks is usually sufficient for healing, and if there is no displacement, gradual weight-bearing can be initiated.
