ABSTRACT

<p><b>OBJECTIVE</b>To investigate the surgical outcome of unilateral pedicle screw(UPS) after TLIF technique combined with contralateral percutaneous transfacet screw(PTS) fixation vs bilateral pedicle screws(BPS) fixation in treatment of degenerative lumbar disease.</p><p><b>METHODS</b>From January 2009 to June 2012, 46 patients with degenerative lumbar diseases, including 30 males and 16 females with an average age of 51.5 years old, who were divided into two groups according to different fixation methods. Twenty-two cases underwent UPS after TLIF technique combined with contralateral PTS fixation (group A), while the others underwent BPS fixation(group B). The relative data were analyzed, such as blood loss volume, operative time, fusion rate, ODI score, JOA score and so on.</p><p><b>RESULTS</b>All the patients were followed up for 1 to 3 years with an average of 22 months. Except one case of each group was uncertainty fusion, the rest have obtained bony fusion, and the fusion rates in group A and B were 95.5% and 95.8%, respectively. No displacement and breakage of screw were found during follow-up. Operative time and blood loss volume in group A were better than of group B(<0.05). ODI and JOA scores had improved obviously than preoperation(<0.05), but the differences had no statistical significance between two groups(>0.05).</p><p><b>CONCLUSIONS</b>Two approaches had similar clinical outcomes for degenerative lumbar disease with no severe instability. Compared with BPS fixation, the UPS after TLIF technique and contralateral PTS fixation has the advantages of less trauma, shorter operative time and less blood loss, and it is a safe and feasible surgical technique.</p>

ABSTRACT

OBJECTIVE: The authors evaluate results of transfacet pedicle sparing approach for high lumbar disc herniation to avoid injury of nerve roots and the cauda equina. METHODS: Seven patients treated by transfacet pedicle sparing approach for high lumbar disc herniation were reviewed. Some thoracolumbar kyphotic patients on whom posterior procedures underwent additional posterior lumbar interbody fusion and posterolateral fusion using the mesh cage and spinal instrumentation. RESULTS: Clinical symptoms improved in all seven patients. Rigid spinal stability and correction of thoracolumbar kyphosis could be performed by the spinal instrumentation methods. CONCLUSION: The advantages of the transfacet pedicle sparing approach are less invasive, easy decompression the nerve root directly and avoidance of the risk of injury to the cauda equina while the dura is being retracted. Additionally, thoracolumbar kyphosis could be corrected. Transfacet pedicle sparing approach is an useful procedure in the surgical treatment of high lumbar disc herniation.
