Application Value Of Small Surgical Incision Bilateral Spinous Process In Posterior Single Level Lumbar Interbody Fusion

Objective:Forward-looking the results of small surgical incision bilateral spinous process and traditional open surgical incision in posterior single level lumbar interbody fusion, to assess the application value of the small surgical incision bilateral spinous process in posterior single level lumbar interbody fusion.Methods:Since November 2006～July 2008 under the lumbar spine of 78 patients with single segment posterior lumbar interbody fusion, prospective patients were randomly divided into small surgical incision bilateral spinous process group (Hereinafter referred to as small-incision group) of 40 cases and 38 cases of conventional open group. Small incision group,21 males and 19 females, aged 35 to 64 years, average 51.9 years old.7 cases of lumbar spinal stenosis, lumbar intervertebral disc herniation with stenosis in 9 cases, posterior edge separation of the vertebral body in 4 cases, discogenic low back pain in 4 cases,16 cases of lumbar spondylolisthesis. Traditional open group,18 males and 20 females, aged 35 to 64 years, mean 53.8 years. 6 cases of lumbar spinal stenosis, lumbar intervertebral disc herniation with stenosis in 10 cases,posterior edge separation of the vertebral body in 3 cases, discogenic low back pain in 4 cases,15 cases of lumbar spondylolisthesis.General information in patients with preoperative groups were comparable. Two groups respectively operative time, blood loss, postoperative drainage, X-ray projection operation frequency,postoperative low back pain VAS score, hospital stay, complication rate, Oswestry functional disability index, interbody fusion rate were compared.Results:78 cases of patients were followed up for 12 to 24 months, an average of 16 months. Two groups of patients the operation time, the number of X-ray projection, complication rate, fusion rate P>0.05 statistically significant difference was not significant. But the small incision group blood loss, postoperative drainage, postoperative low back pain VAS score, hospital stay, postoperative Oswestry functional disability index and traditional open surgical group P<0.05 significant difference.Conclusions:small surgical incision bilateral spinous process and traditional open surgical posterior lumbar interbody fusion were satisfied with the efficacy, but small surgical incision bilateral spinous process with less trauma, shorter hospital stay, rapid postoperative recovery, postoperative VAS score and the Oswestry low back pain dysfunction of the advantages of lower index.
