Abstract


Objective: Anatomy means to observe and measure the value of the human lumbar ventral of macrovascular mobile degree draw the surgery window of size , to provide a reference for the Clinical lower lumbar anterior surgery operation ; especially laparoscopic lumbar Road surgery , in order to avoid serious complications such as vascular injury . On this basis , the preliminary study of laparoscopic lumbar artificial disc replacement clinical applications and short-term Efficacy . Methods : the first part of this study, measurement and its significance for of macrovascular mobility in the lower lumbar ventral . Intraoperative measurement of 40 cases of the adult lower lumbar ventral macrovascular mobile degrees , clear under surgery of lumbar intervertebral space in front of the window size anatomical parameters were statistically analyzed . The second part of the clinical application of laparoscopic lumbar artificial disc replacement surgery , a preliminary evaluation of its clinical efficacy , sum up experience . Results: The measured ① L4 / 5 disc width of 5.8 ± 0.5cm ; ② at L5/S1 intervertebral disc width of 5.8 ± 0.6cm ; ( 3 ) L4 / 5 disc levels in the natural state of the left edge of the inferior vena cava or the left common iliac vein to the corresponding segment the disc left edge of the vertical distance of 5.2 ± 3.1 ± 1.5cm, the lysis stretch state 1.2cm ; ④ natural state the L5/S1 intervertebral horizontal iliac vessels on both sides ( the left common iliac vein to the right common iliac artery ) the distance between the release traction state 3.7 ± 1.4cm, 5.7 ± 0.5cm. The operative time 90-180min, average 136min; 80- 360ml blood loss , an average of 120 ml . After 3 days , 4 weeks , 6 weeks after lumbar X - ray results show that in addition to 1 false bad body position , the remaining loose , shifting and sinking. Followed up for 2-60 weeks , with an average follow - up of 28 weeks , patients with low back pain symptoms were eased significantly from an average of 13.5 in the preoperative JOA score assigned after an average of 24.6 points , 71.6% of the average rate of improvement . Short - term follow-up showed no significant complications . Conclusion: Laparoscopic under the range of movement of the large vessels of the lumbar ventral operating window , to meet the needs of lumbar artificial disc implant . With the advances in spine surgery minimally invasive and non-fusion technology , laparoscopic lumbar artificial disc replacement surgery is expected to become a new tool for the treatment of severe discogenic low back pain .
