The purpose of this study is to investigate a new surgical technique of minimally invasive anterior lumbar interbody fusion(mini-ALIF) combined with percutaneous pedicle screw fixation(PF) without posterior decompression for the treatment of leg pain due to low-grade isthmic spondylolisthesis(grade I or grade II).
The authors retrospectively reviewed clinical and radiological data of 166 patients who had isthmic spondylolisthesis with leg pain or neurogenic intermittent claudication. All patients underwent mini-ALIF and percutaneous PF on the same day between October 2000 and July 2002. There were 58 males and 108 females with a mean age of 49.2 years (range, 19 to 84). The mean follow-up period was 18.4 months(range, 13 to 34). The clinical outcome was graded according to a modified Macnab criteria.
The mean operating time, blood loss, and hospital stay were 217 minutes, 153 ml, and 3.9 days, respectively. No blood transfusion was necessary. Excellent or good outcome was obtained in 155(93.4 %) of 166 patients. There were 7 cases of mini-ALIF complications and 9 cases of percutaneous PF complications. There were no postoperative neurologic deficits.
Simultaneous combination of mini-open ALIF and percutaneous PF is a useful alternative for the treatment of leg pain due to low-grade isthmic spondylolisthesis.
