ABSTRACT

Objective. To value the result in the surgical treatment of the lumbar vertebral spondylolisthesis, isthmic variety of a single level L₅-S₁, with reduction of the vertebral disruption, liberation of the rachidial channel for later via and rigid instrumentation transpedicular L₄-L₅-S₁. Bottom data: The later fixation of the spine and liberation provides the radicular decompression in a direct form, the reduction of the listesis and the stability. Material and method. This study was made in the Hospital Juarez of Mexico in 10 patients, of both sexes, from January of the 2003 to December of the 2004. To all the patients, they were made simple x-rays of the lumbosacra column I position AP and lateral, in neuter position, flexion and extension maxims and oblique to value the lysis of the isthmic. The image study was supplemented with magnetic resonance to value lesion of the intervertebral disk and radicular compression. Results. The lumbar pain and neurological commitment when making the liberation for laminectomy, reduction of the listesis and stabilize the column with metallic instrumentation they were immediately, the integration of the implant and the arthrodesis were achieved in a lapse 5 to 7 months of postoperative. As alone complication it is report a case of rupture of the fixation material form bad placement of this, having to made a new surgery to the patient for placement a new instrumentation. Conclusions. The treatment of the vertebral spondylolisthesis L₅-S₁ isthmic variety with laminectomy, bilateral foraminectomy and disectomy causesbigger vertebral unstability, with the metallic vertebral fixation of the levels L₄-L₅-S₁, we can achieve; the reduction of the listesis, stability of the spine and the integration of the autologus bony implant, to reach the arthrodesis.
