Abstract
Study Design
Prospective analysis was based on radiographic appearance in 80 cases of spondylolisthesis taken in positional change.
Purpose
The aim of the study was to investigate the flexion-extension lateral radiographs about the difference between decubitus and upright position and the measurement method of displacement in spondylolisthesis.
Summary of Literature Review
A lthough the flexion-extension lateral radiographs of spine were known the most preferable diagnostic method for spine instability, there are some debates about the difference of displacement according to the patient position and measurement methods.
Materials and methods
The radiographs of 80 patients with spondylolisthesis were taken in the decubitus and upright position. Extent of the displacement were measured by Taillard, DuPuis, modified Qunnell & Stockdale method and Ferguson angle, slip angle, lordosis angle and vertebral centroid measurement of lumbar lordosis(CLL) were measured, according to position.
Results
Significant difference between the positions was shown on the CLL and lordosis angle. Differences between positions analyzed from Taillard, DuPuis, modified Qunnell & Stockdale method, Ferguson angle and slip angle had no statistical significance. Differences between positions analyzed from the pathologic movement of translation(>4 mm) had a clinically significance in the upright position rather than the decubitus.
