Abstract
There have been many reports regarding various operative methods for spondy lolytic spondylolisthesis. However, there have been no reports regarding th e comparison between posterolateral fusion (PLF) with pedicle screw fixatio n (PSF) and anterior lumbar interbody fusion (ALIF) with PSF. The purpose o f the current study was to compare the clinical outcomes of PLF with PSF an d ALIF with PSF, and to help in the selection of treatment options. Fifty-s ix patients with spondylolytic spondylolisthesis who underwent PLF with PSF (group 1, 35 patients) or who underwent ALIF with PSF (group 2, 21 patient s) were studied. Minimum follow-up was 2 years. Demographic variables and d isease state were similar for the two groups. We studied operating time, am ount of blood loss, duration of hospital stay, clinical outcomes, complicat ions, time at which fusion was complete, fusion rate, and radiological meas urements. There were no significant differences between the two groups in t erms of the amount of blood loss, duration of hospital stay, back pain radi ating pain, fusion rate, or complication rate. However, in group 2, the ope ration time and the time at which fusion became complete was longer, and in group I there was significant radiological reduction loss. In conclusion, PLF with PSF was just as effective as ALIF with PSF in terms of clinical ou tcomes, but ALIF with PSF was superior to PLF with PSF in terms of the prev ention of reduction loss. Anterior support would be helpful for preventing reduction loss in cases of spondylolytic spondylolisthesis of the lumbar sp ine.
