A Minimally Invasive Surgical Technique for Hallux Valgus Deformity Correction Using an Ultrasonic Bone Scalpel (All India Institute of Medical Sciences Technique).

Abstract

Hallux valgus is a common forefoot deformity characterized by medial deviation of the first metatarsal and lateral deviation of the hallux. More than 150 procedures have been described for the hallux valgus deformity with no proven superiority of one over the other. The initial osteotomies are open, and with the advent of power and micro instruments, the osteotomies were manageable via mini incisions and percutaneous procedures. The minimally invasive procedures have been divided into three generations. The first-generation osteotomies involve wedge correction. The second and third-generation osteotomies are translational. The second generation is a simple osteotomy, and the third is a chevron-type osteotomy. In our technique, we have used a hybrid procedure of second and third-generation procedures. The technique uses an ultrasonic bone scalpel to create a transverse sub-capital osteotomy which is then fixed with screws for a stable construct.
