Abstract
Objective:To discuss the function of mixed reality (MR) technology in guiding location of intervertebral foramen microscopic puncture and analyze its feasibility and clinical application value.Methods:Sixty patients with lumbar intervertebral disc who were treated between January 2017 to October 2017 were chosen, and classified into navigation group (30 cases) and traditional control (30 cases) according to random number table. Intervertebral foramen microscopic operation was conducted for both groups. MR technology was applied for the navigation group to guide puncture and establish intervertebral foramen microscopic cannula. Traditional C-arm X-ray apparatus was used for traditional group to establish intervertebral foramen microscopic cannula. Intra-operative puncture times, fluoroscopy times, puncture time and VAS score 1d, 3m and 6m after the operation were recorded and compared.Results:Postoperative waist and leg pain symptoms of both groups were relieved obviously, and straight leg raising test for the diseased limb turned to be negative. Intra-operative puncture times, fluoroscopy times, puncture time and operation time had statistical significance decrease.Conclusion:Mixed reality (MR) can accurately guide the establishment of intervertebral foramen microscopic cannula, solve the bottleneck problem of intervertebral foramen microscopic technology, promote puncture success rate, reduce repeated puncture times, avoid by-injury, shorten puncture time and reduce X-ray radiation quantity of operators and patients, so it deserves to be promoted and applied.
Highlights
Operative treatment of lumbar intervertebral disc herniation has gained the favorable clinical effect
mixed reality (MR) technology was used for the navigation group to establish intervertebral foramen microscopic cannula, while the traditional group adopted traditional C-arm x-ray apparatus to establish intervertebral foramen microscopic cannula
With the rapid development of minimally invasive technology, treatment of lumbar intervertebral disc herniation with minimally invasive surgery has become a trend of spine surgery
Summary
Operative treatment of lumbar intervertebral disc herniation has gained the favorable clinical effect. Intervertebral foramen microscopic technology punctures from the rear side of lumbar vertebra under local anaesthesia, which will neither damage the rear muscle nor destroy important arthrosis ligament structure of lumbar vertebra. It has no obvious influence on lumbar vertebra stability. Thirty patients who received lumbar intervertebral disc excision by intervertebral foramen microscopic technology were studied and the good clinical effect was gained. They were compared with 30 patients for whom traditional C-arm X-ray apparatus was used to guide cannula establishment. The reason was to document the differences between both traditional or the MR technique
