Abstract:
Objective To explore the effect of gravitational traction on height change of degenerative disc of New Zealand white rabbit.Methods In order to create intervertebral disc degeneration models, the right front side of the annulus fibrosus of lumbar vertebrae of rabbits were damaged by 16-gauge needle. After confirming the success of modeling, 20 animal models were randomized into 2 groups, 15 of which received a routine gravitational traction using a model of our own design, 30 min per day, for 8 weeks, while the control group received no treatment at all. Radiographic exam were performed in the 2nd, 4th, 6th and 8th week, after intervention and the disc height index percent (DHI%). Results Compared to the baseline, DHI% increased significantly 2 and 4 weeks after gravitational traction (P<0.05), and there was no further effect as the traction continued. However, compared to the control group, an improvement of DHI% was found on all the time points in the gravitational traction group (P<0.001). Conclusion Gravitational traction may delay and inhibit intervertebral disc degeneration by increasing height of degenerated disc of New Zealand white rabbit.
