Posterior Agumentation with Rectangle Luque for the Treatment of Tuberculosis of the Lumbosacral Junction in Adults / 대한정형외과학회잡지

ABSTRACT

From September 1987 to June 1994, the authors had performed posterolateral fusion in one patient, anterior spinal fusion alone in four patients, anterior spinal fusion after posterior augmentation with Rectangle Luque and posterolateral fusion in four patients of tuberculosis of the lumbosacral junction. The purpose of this study was evaluated the reliability of the posterior augmentation with Rectangle Luque and posterolateral fusion. We divided into two groups the study group was anterior spinal fusion after posterior augmentation with Rectangle Luque in four patients, the control group was anterior spinal fusion alone in four patients. The average follow up was obtained at 16 months(12 to 20 months) in study group, at 42.7 months in control group. Results were as follows 1. Clinical results according to Moskowitz criteria were 2 patients with grade I. 2 patients with grade II in the study group; one patient with grade I, one patient with grade II, one patient with grade III, one patient with grade IV in the control group. Hypolordosis(less than 10 degree) at the lumbosacral junction was associated with a higher incidence of back pain. 2. Radiographically well consolidated anterior fusion was noted in all patients within average 6 months (5-7 months) in the study group and 7.2 months (5-10 months) in the control group. 3. Radiologically the lumbosacral saggital angle was corrected after operation and the mean angle was 16.5 degrees(12 to 20 degrees) in the study group, 7.2 degrees(3 to 20 degrees) in the control group. The mean loss of angular correction was 5 degrees(1 to 8 degrees) in the study group, 6.2 degrees(1 to 13 degrees) in the control group at postoperative one year follow up. In conclusion, this results suggest that the anterior spinal fusion concomitant with the posterior augmentation with Rectangle Luque is the recommendable methods for tuberculosis of the lumbosacral junction in adults.
