Abstract:
BACKGROUND:The patients with lumbar intervertebral disc protrusion can be treated with internal fixation of posterior surgery way. We can choose the conventional posterior intervertebral fusion nail stick system internal fixation. Isobar non-fusion internal fixation system was used in recent years. As a kind of a strong internal fixation of lumbar posterior dynamic screw rod fixation system, it has been gradual y applied in clinic, and has been one of patient’s treatment options. OBJECTIVE:To compare and analyze the clinical efficacy of Isobar non-fusion internal fixation system and traditional intervertebral fusion nail rod system internal fixation operation method in treatment of lumbar disc herniation. METHODS:From September 2011 to September 2012, 40 patients with lumbar disc herniation who were treated in the Department of Orthopedic, Changhai Hospital, the Second Military Medial University of Chinese PLA were enrol ed in this study. They were equal y assigned to the Isobar non-fusion internal fixation system group (Isobar group) and the traditional intervertebral fusion nail rod system internal fixation group (rigid internal fixation group) and subjected to corresponding treatments. RESULTS AND CONCLUSION:Surgery was successful y completed in patients of the two groups. These patients received at least 2 years of fol ow-up, no drop out. Compared with pre-fixation, low back pain Visual Analog Scale and Oswestry Disability Index were improved significantly after fixation in both groups. Compared with the rigid internal fixation group, range of motion of lumbar spine was larger in the Isobar group. Low back pain Visual Analog Scale and Oswestry Disability Index were similar between the two groups. These results indicated that posterior Isolbar non-fusion internal fixation obtained identical outcomes as traditional treatment, and showed more advantages in range of motion of lumbar spine.
