Background: Surgical techniques used in the treatment of patients with high grade lumbar spondylolisthesis (> 50% slippage) areusually associated with a great deal of controversies. We aim to evaluate the surgical outcomes of high grade spondylolisthesistreated with an intraoperative temporary distraction rod. Methods: We retrospectively studied 21 patients (14 females and 7 males), aged 50.4 ± 9.2 years, who had high grade lumbarspondylolisthesis that was treated with intraoperative temporary distraction rods, neural decompression, pedicular screw fixation,and posterolateral fusion involving one more intact upper vertebra. The mean follow-up period was 39.2 months. Radiologic andclinical outcomes were measured by slip angle, slip percentage, correction rate, Oswestry Disability Index (ODI), visual analoguescale (VAS), patient’s satisfaction rate in the pre- and postoperative period. Data were analyzed by SPSS ver. 11.5. Results: Analysis of the preoperative visits and final follow-up visits indicated that surgery could improve ODI, lumbar VAS, andleg VAS from 60.5% to 8.2%, from 6.7 to 2.2, and from 6.9 to 1.3, respectively. Slip angle and slip percentage were also changedfrom –8° to –15° and from 59.2% to 21.4%, respectively. Mean correction rate at the final follow-up visit was 64.1%. Loss of correctionwas insignificant and a neurologic complication occurred in one patient due to misplacement of one screw. Excellent andgood levels of satisfaction were observed in 90.5% of the patients. Conclusions: In the surgical treatment of refractory high grade spondylolisthesis, the use of a temporary distraction rod to reducethe slipped vertebra in combination with neural decompression, posterolateral fusion, and longer instrumentation is associatedwith satisfactory clinical and radiologic outcomes.
