Prior to Big Toe Fusion surgical procedure:

How is the Big Toe Fusion surgical procedure Performed?

The Big Toe Fusion Procedure is performed as follows:

  • An incision is made by the surgeon on the medial (inside) aspect of the front of the foot, at the base of the big toe; and, about 3 cm (2-3 inches) long, towards the heel
  • Two screws are drilled into the two adjacent bones. The screw that starts nearest to the big toe goes through the bone nearest the toe and is aimed at an angle back towards the heel
  • The tip of that screw ends up in the same bone the next screw starts in. The other screw starts closer to the heel, and the tip then ends up in the same bone the other screw started in
  • The surgeon has to make sure the screws are offset a little, so they do not strike each other half way through. So, the previously mobile joint will no longer move because the two screws hold it stiff
  • On a post-operative X-ray, the two crossed screws are checked for proper placement. The incision(s) is/are closed with sutures, a dressing applied, and the foot wrapped up
  • No plates are used in this procedure, just the two screws. The screws stay in place for the duration of the patient’s life

Prior to the surgical procedure, the following may be necessary:

  • Preoperative physical examination to evaluate the patient is fit to undergo the procedure
  • Preoperative laboratory testing
  • Evaluation of medication history and safety of anesthesia planned
  • Arrival at surgery location fasting

What Post-Operative Care is needed at Home after the Big Toe Fusion surgical procedure?

At home, the following post-operative care may be recommended, after a Big Toe Fusion Procedure:

1 to 7 days after the procedure:

  • Begin the course of prescribed medication to reduce pain, as advised by the physician
  • Elevate the foot while resting, to prevent formation of blood clots and reduce the possibility of swelling
  • Keep the wound bandaged for about 2 weeks post-surgery. It is applied in the operating room and is used to help reduce swelling. Avoid getting the gauze bandage wet

8 to 14 days after the procedure:

  • Continue to elevate the foot while resting
  • By this time, individuals may be able to walk short distances. Make sure to continuing wearing the orthopedic walking boot, prescribed by the healthcare provider
  • Avoid smoking and taking anti-inflammatory medications during the first few weeks after surgery as this may delay or prevent the bones from fusing together

15-21 days after the procedure:

  • Recovering from Big Toe Fusion surgery differs from one individual to another. After about 2 weeks post-surgery, individuals with a sedentary job may return to work, if elevation of the foot is possible
  • It may take about 2 to 3 months for individuals with labor-intensive type jobs to return to work

1 month after the procedure:

  • If a medical professional prescribes an antibiotic ointment, apply the ointment to the healing wound. Continue to apply the ointment to the wound once it is completely healed
  • Wash the surgical wound with mild soap while bathing; keep it clean and dry thereafter

2 to 3 months after the procedure:

  • At this point, an individual’s mobility will be improved. However, it is recommended to avoid walking long distances
  • Individuals with a job that is more labor-intensive should discuss with their healthcare professionals about returning to work
  • Individuals may slowly resume low impact exercises, such as cycling, exercise bike, and cross training. High impact exercises, such as running may begin about 3 months after surgery, as advised by the surgeon

3 months to 1 year after the procedure:

  • 6 months after surgery, individuals can probably return to normal sports activities
  • Individuals are advised to refrain from flying in the first 3 months after surgery due to the increased risk of developing blood clots during this time frame
  • Swelling of the foot may still be noticeable for up to a year after surgery

In general, the following post-operative instructions may be given by the surgeon/healthcare expert:

  • Leave the dressing applied in the OR intact until suture removal visit, which may be after 10-14 days, or as advised
  • Painkillers may be prescribed, which may be required for a few days after surgery
  • Partial weight bearing as tolerated may be considered after 24 hours (next day) following surgery
  • Crutches or walker may be used for support
  • A stiff flat-soled Velcro mini-boot on each foot may be used, to keep the foot and toe joints from moving for about 6 weeks, or as recommended
  • A follow-up X-ray may be then taken to assess healing, following which one may use regular shoes
  • Physical therapy visits may be needed and planned
  • The physiotherapist will advise when normal physical activities, such as walking, tennis, or swimming, may be resumed

How long does it normally take to fully recover, from the Procedure?

It may take about 6 weeks to recover from the Big Toe Fusion surgical procedure. At this time, individuals may be able to participate in low impact sports.

Additional Information:

What happens to tissue/samples (if any), taken during the Procedure?

The tissue is taken for further examination and later disposed, as per the standard medical procedure.

When should you expect results from the pathologist regarding tissue taken out, during the Procedure?
