ABSTRACT
OBJECTIVE:
We sought to measure the coronal alignment of the lumbar spine of patients in the right lateral decubitus position on a hinged Jackson operating table with the following 3 table positions neutral and right and left 20-degree flexion.METHODS:
We analyzed the data of 23 patients who underwent OLIF. Spinal alignment was quantified using the coronal Cobb angle from L1 to S1, measured on anterior-posterior radiographs obtained preoperatively, after induction of anesthesia, with patients in the right lateral decubitus position, for the following 3 positions of the Jackson hinged operating table neutral, right 20-degree flexion, and left 20-degree flexion. The Cobb angle at each position, the change in the Cobb angle, and the effective range of motion (%) were obtained from neutral to right and left 20-degree flexion. Alignment was compared between the 3 positions, and the range of motion was compared between men and women.RESULTS:
The Cobb angle was different in all 3 positions of the table (P < 0.0001) -7.0 ± 8.7°, neutral; 2.8 ± 7.6°, right 20-degree flexion; and -14.7 ± 7.8°, left 20-degree flexion. The change in Cobb angle and the effective range of motion were greater in women (10.9 ± 2.8° and 55%) than in men (6.7 ± 5.8° and 34%) from the neutral to right 20-degree flexion position (P = 0.0298).CONCLUSIONS:
The coronal alignment of the lumbar spine of patients in the right lateral decubitus position on a flat operating table (neutral position) was convex. The right 20-degree flexion position of the hinged operating table yielded less coronal plane lumbar spine deformity, with greater deformity in women.Palabras clave
