Am considering bunionectomy for moderate bunion. dr wants to use a screw and i am opposed. is there any way to cut and realign bone without using scr?

No screw loose.: There certainly is. I have used K-wires as well as screws for fixation for years. Either one works just fine. The K-wire does not remain in the wound as it is removed after several weeks. The removal is performed in the office and is generally not painful at all. There are some surgeons that often use no fixation at all, relying on bandaging for adequate immobilization. Not recommended by me.

PROBABLY, BUT....: There are many ways to cut the bone, to fix the bunion. Thinking of the various osteotomies, I think all can be stabilized with K-wires, which can be removed later. The advantage to screws is that they really compress the bone together; K-wires don't provided compression, only hold the bone together. Also, there are "dissolving" pins or screws; ask your surgeon if this is an option.

BUNION: The operation chosen by the specialist depends on the severity of the bunion, the shape of your foot, and other factors, such as if you have arthritis in the joint. There are many different types of operation which are used to treat bunions. These range from operations to trim parts of the joint, to a total artificial replacement of the big toe joint (similar to a knee or a hip replacement). A common surgical procedure used is called a scarf osteotomy (osteotomy means a cut in the bone).

That would depend on: the type of bunionectomy being performed. they can use a wire, a disappearing wire but there is nothing wrong with using a screw, it is very common. If for whatever reason you don't want it in it can be removed after the procedure heals.
