Background: A standard spinal traction (ST) device was designed to straighten the spine and improve spinal alignment to relieve pain in patients with disk disease. Although it was theoretically expected to have an effect on spinal decompression, its clinical effects have been disappointing. Because previous ST devices decompress the whole spinal structure equally without maintaining the lordotic curve, unnecessary pain could develop. Thus, our study was aimed at evaluating geometrical changes using radiography when spinal traction was applied by Lordotic Curve Controlled Traction device (LCCT), a device developed by the authors.
Methods: Herein, 40 patients with or mild non-radicular low back pain (LBP) were included. The participants were scheduled to receive LCCT or ST in random order. Anterior and posterior intervertebral distance and the ratio of anterior-to-posterior intervertebral distance (A/P ratio) during traction were calculated. Lordotic angles of intervertebral bodies (L2~L5) were measured by radiography.
Results: Mean intervertebral distances were greater during LCCT than those measured before applying traction (p < 0.05). Mean A/P ratio was also significantly greater during LCCT than during ST or before applying traction (p < 0.05). In particular, for the L4/5 intervertebral segment, which is responsible for most of the lordotic curve, the mean LCCT angle was similar to mean lordotic angle in the standing position (10.9°).
Conclusion: Based on the measurements of radiologic geometrical changes, the newly developed LCCT appears to be a useful traction device for evenly increasing the intervertebral disk space while maintaining the lordotic curve in the clinical setting.
