Minimally invasive percutaneous surgical techniques with internal fixation for correcting hallux valgus
Closed for comments This consultation ended on at Request commenting lead permission
Description
Hallux valgus is a deformity of the big toe joint, often causing pain in the foot. The big toe bends towards the other toes, and a bony lump (called a bunion) appears on the side of the foot at the base of the big toe.
Under local or general anaesthesia, 1 or more small cuts are made through the skin (percutaneous) of the big toe. Bone-cutting surgical tools are put through the cuts and are used to remove the bunion and divide 1 or more of the bones at the front of the foot. The divided bones are secured either with wires, screws or plates (internal fixation). The operation is monitored using X‑rays or an endoscope (a thin, flexible tube with a camera on the end). The aim is to straighten the big toe joint to reduce pain and other symptoms and preserve joint movement. Compared with standard (open) surgery, this procedure uses smaller cuts to the foot (minimally invasive).
