Severe surgical trauma is detrimental to the patient’s postoperative recovery, and large scars can have a huge psychological impact on the patient and stay with him/her for life. Therefore, minimally invasive surgery has become the direction of modern orthopedic surgery. The main purpose of minimally invasive spine surgery is to obtain better surgical results by minimizing medical (including physiological and psychological) injuries during the surgical access and operation through various minimally invasive systems, surgical procedures and techniques, while ensuring surgical results. Minimally invasive spine surgery using the Medtronic Expandable Access Surgical System (MAST Quadrant?) is one of the specialties of our orthopedic department. The advantage of minimally invasive surgery over traditional spine surgery is that instead of extensive soft tissue debridement and exposure, a series of step-by-step expansion tubes are used to expand through the lumbar paraspinal space to create a working channel in which the thoracic and lumbar segments can be surgically exposed, decompressed, braced, fused and fixed. This allows for single-segment or double-segment decompression, fusion or fixation. Minimally invasive spine surgery is less invasive, with small surgical incisions; less bleeding, usually without blood transfusion; less postoperative pain at the surgical site; and quicker recovery, usually 3 days after surgery.
