Abstract

OBJECTIVE:

To explore the method and clinical effect of MAST Quadrant for lumbar spondylolisthesis with adjacent segment degeneration.

METHODS:

From April 2014 to January 2016, 36 cases of lumbar spondylolisthesis with adjacent segment degeneration were treated by MAST Quadrant(target nerve decompression and transforaminal lumbar interbody fusion or articulationes zygapophysiales fusion by unilateral fixation with MAST Quadrant). Twenty-three cases were degenerative lumbar spondylolisthesis and 13 cases were isthmic lumbar spondylolisthesis. According to Meyerding grade of spondylolisthesis, 16 cases were grade I, 17 cases were grade II, and 3 cases were grade III. Visual analogue score (VAS), Oswesty Disability Index (ODI) and JOA score were used to evaluate the clinical outcome.

RESULTS:

The amount of intraoperative bleeding was 230 to 480 ml with an average of 340 ml and the amount of postoperative blood loss was 15 to 80 ml with an average of 43 ml. Operative time was 176 to 240 min with an average of 193 min; X-ray exposure time was 2 to 6 s with an average of 3.6 s. Two cases were complicated with dural tear without nerve injury during operation. Thirty cases were followed up from 12 to 17 months with an average of 15.2 months. VAS scores for preoperative, 5 days, 3 months after surgery were 7.6±1.7, 1.9±0.4, 0.8±0.4 respectively, and there was significant difference before and after operation(P<0.05). The ODI scores for preoperative and 3 months after surgery were 35.9±1.2 and 3.7±0.7 respectively, and there was significant difference before and after operation(P<0.05). JOA scores for preoperative, 5 days, 1 months, 3 months after surgery were 13.2±0.4, 24.4±0.4, 27.4±0.1, 27.9±0.5 respectively, and there was significant difference before and after operation(P<0.05).

CONCLUSIONS:

MAST Quadrant can be applied to treat lumbar spondylolisthesis with adjacent segment degeneration, and the minimally invasive sugical technique is a safe and effective method, with the advantage of simple operation, fast recovery.
