Abstract: ［Abstract］  Objective〖HTSS〗〓To observe the clinical effect of modular decompression combined with interbody fusion in the treatment of lumbar disc herniation.
〖HTH〗〖WTHZ〗Methods〖HTSS〗〓Seventyfive cases of lumbar disk hernitaion patients were divided into 2 groups based on the operation procedure they accepted. Thirtysix patients accepted modular decompression combined with interbody fusion(modular decompression group). Thirtynine patients accepted normal laminectomy combined with interbody fusion(conventional decompression group). The operative time, intraoperative blood loss, Japanese Orthopaedic Association(JOA) scores and Visual Analogue Scale(VAS) were recorded and analyzed.
〖HTH〗〖WTHZ〗Results〖HTSS〗〓No spinal cord and nerves injury occurred during the surgery. The operation time and intraoperative blood loss in modular decompression group were lower than those in conventional decompression group(P＜005). The JOA scores of the 2 groups were gradually increased when compared with the preoperation(P＜005). There was no significant difference between groups and intergroup interaction between time points(P＞005). The VAS score of lower back pain in the 2 groups were first increased and then decreased(P＜005), and modular decompression group was lower than conventional decompression group(P＜005). There was significant difference among groups, time points and intergroup interaction between time points(P＜005).
〖HTH〗〖WTHZ〗Conclusion〖HTSS〗〓Compared with the normal laminectomy, modular decompression could reduce the operation time, control the intranopative blood loss and decrease the low back pain, which is an effective decompression method for the treatment of lumbar disc herniation.
