[Application of robotic assistance in surgical treatment of degenerative disease of lumbosacral spine]

Robotic assistance has gained increasing popularity in spinal surgery recently. Robotic assistance provides higher effectiveness and safety especially in conditions of complicated anatomy. It also enables the novel, previously unavailable surgical techniques, such as GO-Lif for lumbar spine fusion. The aim of the study is to assess the applicability and effectiveness of the robotic assistance in surgical treatment of degenerative lesion of lumbar spine. 16 patients were operated with robotic assistance device (SpineAssist; MAZOR Surgical Technologies, Caesarea, Israel) between August 2009 and February 2010 in Spinal Department of Burdenko Neurosurgical Institute (Moscow, Russia) with degenerative disc disease. Preoperative assessment included MRI, X-rays and high-resolution CT (slice < 1 mm). The CT is essential for preoperative planning using computed work station SpineAssist. The robot was utilized for automated intraoperative positioning of the instruments according to preoperatively planned trajectories. Basic parameters of surgeries were thoroughly recorded: overall surgery time, radiation dose (all manipulations were performed under fluoroscopic control), accuracy of screw placement relative to preoperative planning, which was assessed using postoperative high-resolution CT with 3D reconstruction. Particular interest of the study was focused on the novel fusion technique for lumbar spine: Go-Lif (Guided Oblique Lumbar Interbody Fusion). This fusion modality enables segment fixation with two screws only, it is comparable with pedicular screws in terms of stability, being far less invasive. It may be used standalone or together with TLIF techniques. Robotic assistance enabled optimal screw placement even in complex anatomical cases (thin pedicles and rotational deformity). No implant-related complications were recorded. Surgery time was much longer in first 2 cases, though in further it decreased nearly to conventional (without robot) surgery time. For radiation dose same tendency was observed--in first 2 cases all surgical steps were fluoroscopically controlled, in further cases--only for primary anatomy registration. Based on control CT, accuracy of implant placement with robotic assistance is 1 mm Keywords : Adult,complications,diagnostic imaging,Female,Humans,Lumbosacral Plexus,Male,Middle Aged,Neurodegenerative Diseases,Radiography,Robotics,Safety,Spinal Diseases,Spine,surgery,, Robotic,Assistance,Surgical, nsaids side effects

This surgical technique consists of a percutaneous approach for the treatment of small to medium size hernias of the intervertebral disc by laser energy. The main objective is to reduce the intradiscal pressure in the nucleus pulposus

Laser Disc Surgery can be performed under local anaesthetic as a day case at our centre on the prestigious Harley Street.
