Abstract
Spondylolisthesis is forward slipping of upper vertebra in relations to its lower one, commonest is L4-L5. The ideal surgical treatment of spondylolisthesis is still controversial. Posterior lumber interbody fusion with pedicle fixation is one of treatment choices for the lumber spondylolisthesis. Forty patients who operated through posterior lumber interbody fusion and pedicle screw fixation by single surgeon was included from January 2012 to March 2015. Periodical follow-up was done both clinically and radiologically up to 6 months. Patient outcome was completed based on pain relief graphic rating scale and Oswestry disability index. In our series, the excellent outcome were 25 patients (62.5%), good were 12 patients (30%), and fair were 3 patients (7.5%). There were no poor outcome and no new neurological deficit. This study concludes that posterior lumber inter-body fusion with pedicle is an effective treatment for the lumber spondylolisthesis. It helps to maintain the biomechanics, associated with less complication and improve the quality of life of patient.
Highlights
Spondylolithesis is forward slipping of upper vertebra in relation to its lower one which is classified by Wiltse and Rothman into dysplastic, ishtmic, degenerative, traumatic, pathologic and iatrogenic.[1]
It may be due to ligamentous laxity, a defect in the pars interarticularis, previous surgery, or may be traumatic and up to 5% of the general population suffer from spondylolisthesis and it can occur at any age.[5]
Indication for surgery of spondylolisthesis is intolerable due to low back pain, severe radicular pain, neurogenic claudication, presence of neurological symptoms, conservative treatment failure, increase grading of listhesis, instability confirmed by radiology, Meyerding Grade III and IV listhesis, and spondyloptosis.[2, 5, 6]
