Therapeutic Effect Analysis Of Minimally Invasive Posterior Lumbar Discectomy Assisted With X-Tube System In The Treament Of Lumbar Disc Herniation

Objective To evaluate the clinical value of minimally invasive posterior lumbar discectomy assisted with X-Tube system in the treament of lumbar disc herniation comparing with traditional open posterior lumbar discectomy.Methods Retrospective analysis of 12 patients who accepeted minimally invasive posterior lumbar discectomy assisted with X-Tube system during May 2009 to February 2010. The operative duration, blood loss, hospitalization days after operation, the loss rate of haematoglobin and albumin were evaluated in our study. Meanwile, we took 12 lumbar disc herniation patients who accepcted traditinal open posterior lumbar discectomy as the control group during the same time. Regular follow-up was carried out for these 24 patients to record postoperative complications, and the therapeutic effect was evaluated with the Nakai standard.Results There was no significant difference between the minimally invasive group and the traditional open group in the aspect of operation fineness rate which were both 91.7%. The operative duration, blood loss, hospitalization days after operation, the loss rate of haematoglobin and albumin of the minimally invasive group were 57.83±9.92 min,55.00±9.04 ml,5.67±1.23 days,9.07±2.62%and 9.59±2.62%respectively. And the five indexes in the traditional open group were 67.00±10.77 min,85.42±8.65 ml, 8.50±1.88 days,13.96±4.87%and 14.92±5.57%respectively. Significant differences were exist in the above five indexes between the two groups(P< 0.05).Conlusion Minimally invasive posterior lumbar discectomy assisted by X-Tube system minimize tissue trauma and blood loss, shorten the operation duration and hospitalization time, the short-term therapeutic effects are quite good.
