Bunion Surgery – Minimally Invasive Chevron Procedure (MICA)

The MICA procedure is used to correct a mild-to-moderate hallux valgus and ease bunion pain.

Hallux Valgus, more commonly known as a bunion, is a large, protruding bump on the side of the big toe. Bunions can cause swelling, soreness, and inflammation – although not all bunions are painful. The MICA procedure is a two-phase bunion surgery designed to correct a mild-to-moderate hallux valgus and ease bunion pain. This safe, effective bunion treatment is usually performed under general anaesthesia and you will return home the same day.

Bunion Symptoms

The symptoms of a bunion can include the following:

  • A bump that bulges on the outside of the base of the big toe
  • Swelling, redness and or soreness around the big toe joint
  • Corns or calluses where the big toe overlaps the second toe
  • Restricted and painful movement of the big toe
  • Skin thickening at the base of the big toe

What to expect with MICA surgery

The goal for bunion correction surgery is to relieve as much pain and discomfort as possible and correct the deformity by returning your toe to the correct position. If your surgeon has determined that your bunion needs surgical intervention, the MICA surgical option may be for you. This unique procedure was designed for precise bunion correction surgery. It allows the surgeon to accurately fix the bone and correct the soft tissue issues, which potentially leads to better results for patients. There is even the possibility of weight-bearing shortly after surgery, only with the surgeon’s approval.

During the procedure the surgeon will make a small incision at the base of your big toe, then cut and realign the metatarsal bone, remove any excess tissue or bony growths, and re-align the bone using a small screw for stabilization. Your surgeon will close the incision and bandage your foot.

After Bunion Surgery

The vast majority of patients who undergo bunion surgery or MICA say they are extremely happy with the procedure. While individual results may vary, this is a safe, minimally invasive and highly effective surgical procedure. Bunion surgery relieves the pain, swelling, and misalignment of the metatarsal bone and joint. You should be able to wear comfortable and supportive shoes within 1-2 weeks after your procedure. Minimal risks associated with bunion surgery can include infection, toe stiffness, neuroma (nerve pain), slow healing, and localized numbness. Your surgeon will provide detailed information and follow-up care to ensure you have the best possible outcome and enjoy lasting relief from foot and bunion pain.

You will be provided with a cast boot, prescription, and a Cold Therapy Machine to aid in pain relief and to manage swelling while you heal. Most patients can immediately put gentle weight on the affected foot if they wear a protective, post-surgical cast boot. Depending on the severity of your condition, you may need to use crutches for a few days or stay off the foot for 2-3 weeks. Each patient is different, so your surgeon will tell you the best way to protect your foot and enjoy a prompt, full recovery.

FAQs

What are the goals and benefits of bunion surgery?

The MICA procedure is an innovative new option for those suffering from a bunion or hallux valgus. It is an effective way to permanently treat the pain, soreness, stiffness, and limited mobility caused by foot bunions. If you’re experiencing severe foot pain – even when wearing comfortable, supportive shoes – and the swelling and stiffness are affecting your daily activities, bunion surgery can provide relief. It can also prevent further damage to the joints and cartilage in your toe, which could eventually lead to arthritis. Some of the benefits of the MICA procedure over traditional bunion surgery is that it offers a quicker recovery as there is no need to wait for the bone to fuse, less pain as the incision is smaller, more mobility sooner, you will be up and around in half the time.

What is this procedure for and how will it alleviate my symptoms?

MICA stands for Minimally Invasive Chevron Akin. The MICA procedure is a much less invasive method of correcting bunions and hallux valgus (big toe turning outwards). Not all bunions cause pain, however the angulation of the big toe can also cause pressure on the second toe, which can also become deformed (called a hammer toe). In some cases, the first two toes will cross over, which can then cause a lot of pain in shoes.

What happens during surgery?

The first step is to have standing x-rays completed for both feet. This can be arranged by your family physician. Not all diagnostic facilities do standing x-rays, so make sure to ask before you go. Prepare your questions for the surgeon to answer during your consultation. Try and maintain as much range of motion in your great toe as possible. Your surgeon may suggest that you lose weight and initiate an exercise program to achieve the most successful recovery. Smoking can significantly affect the healing process. If you smoke, be sure to speak with your surgeon about it, as smoking can dangerously increase surgical risks and slow down the healing process.

How do I qualify for this procedure?

All patients are required to complete a Pre-Surgical Patient Questionnaire to provide us with your basic medical history. We also request your most recent x-rays and should these confirm you are a suitable patient for the procedure and our facility we will request a History and Physical Form be completed along with bloodwork and ECG via your family doctor. The decision whether or not to offer the MICA procedure is made by an experienced orthopaedic surgeon. Although there are non-surgical options to manage the symptoms, nothing other than surgery can correct a bunion once it has formed.

What is the average process like and how long will it take for me to return to my normal activities?

The goal of bunion correction surgery is to realign the bones, eliminate the bump and create a straight big toe. During the procedure the surgeon will make a small incision at the base of your big toe, then cut the bones using a small (2mm) drill under x-ray guidance. The next step is to realign the metatarsal bone, remove any excess tissue or bony growths, and re-align the bone using small specially designed screws for stabilization to ensure the bones remain in the corrected position whilst they heal. Your surgeon will close the incision and bandage your foot.

How should I prepare for my surgery?

As your procedure uses these specialty screws and you will be provided with a special protective cast boot you can immediately put gentle weight on the affected foot. While individual results may vary, you should be able to wear comfortable and supportive shoes within 4-6 weeks after your procedure. You will be provided with the specialty cast boot, post-op medication prescription, and a Cold Therapy Machine to aid in pain relief and to manage swelling while you heal. It is not uncommon to have swelling for 4-6 months’ post-surgery. You will be limited in movements for the first 2 weeks but most people with sedentary jobs can return after that. For active, physically demanding occupations, 6 weeks may be required. Driving will be limited until your surgeon advises it is safe to do so. Physiotherapy or Occupational Therapy after 6 weeks’ post-op may assist in your recovery by helping to restore a normal gait and, massage and mobilization of the joints to reduce swelling. Typically, No exercising until at least 2 months’ post-op and no impact exercise until 4 months’ post-op.
