Expanding the horizons of minimally invasive spine surgery

Abstract

The trend of using smaller operative corridors is observed in various surgical specialties. The development of smart technologies with the overall aim of reducing surgical trauma has resulted in the concept of minimally invasive surgical techniques. Enhancements in microsurgery, tubes, endoscopy, and various percutaneous techniques, as well as improvement of implant materials, have proven to be milestones. The ease of performing surgery through tubes has recently evolved into percutaneous placement of spinal instrumentation, including intervertebral spacers, rods, and pedicle screws. The advancement of training of spine surgeons and the integration of image guidance with precise intraoperative imaging, computer-, and navigation-assisted treatment modalities constitute the era of reducing treatment morbidity in spinal surgery. This progress has led to the present era of preserving spinal function. In this report, we present a chronological perspective of the use of tubular retractors, the learning curve of tubular retractor in dealing complex cases and its wide applications, and expanding the horizon using tubular retractors.
