This procedure is generally performed as a day case operation. You will be coming to the day case reception lounge on the day of operation. You will be checked into preoperative lounge and will be met by the surgeon and the anaesthetist who will go through all the benefits and risks of the surgery again. Surgery is performed under general anesthetic, usually as a day case. The procedure takes approximately 30-60 minutes. The aim of surgery is to improve pain and function as well as the appearance of the toe.
A 4cm incision is made on the top of the foot between big and second toes to release the tight structures on that side.
An 8cm incision is made on the inner aspect of the foot over the bunion. Some of the underlying bony prominence is shaved off then the bone is divided so that it may be re-aligned. The bone is stabilized with 1 or 2 screws that are completely embedded within the bone. Because the screws are embedded you will not be able to feel them, and they should not require removal at a later date.
The tissues are then stitched, and a wool and crepe bandage applied.

We advice heel walking for first two weeks with crutches which physiotherapists will train you before discharge. A special shoe has been supplied for you wear over your dressings that should be worn during the day for 6 weeks. It is necessary for you to walk by taking the weight on your heel so that you don’t put pressure on the big toe. It is not necessary to wear this shoe in bed.
You will be reviewed approximately 2 weeks following surgery, and the dressings and sutures will be removed. At this stage you will be placed in a removable splint. You will still need to continue wearing the special shoe for 6 weeks. You will be reviewed again after 6 weeks at which time you will have an X-Ray. If all is well, you will be referred to the physiotherapists and you can discard the post- operative shoe. The foot is often slightly swollen at this stage and so a comfortable pair of loose-fitting shoes or trainers will need to be worn and should be brought to the clinic. You will then be reviewed, hopefully for a final check, at about 3 months after the surgery.
