Filter by:The goal of this interventional study is to is to compare the effect of a tap block versus a placebo in patients undergoing anterior lumbar spine surgery. The main question it aims to answer : • whether tap block can reduce the need for postoperative pain medication Participants will be randomized into two groups and all postoperative pain medication will be recorded over 3 days. Researchers will compare tap block vs placebo to see if it reduces postoperative pain.
Lumbar fusion is an accepted and effective technique for the treatment of lumbar degenerative disease. As the population ages, disability associated with spinal pathology and spinal surgery is rapidly increasing and there is a concomitant increase in prevalence of osteoporosis which is a detrimental factor for Lumbar fusion and instrumentation. Osteoporosis-related bone fragility is a primary reason for spinal fusion failure, implant fixation failure, and vertebral compression fractures above or below the fusion sites. Denosumab is a human monoclonal antibody against RANKL, it inhibits osteoclast mediated bone destruction and has been found to be effective in treating osteoporosis, including reducing bone turnover markers, increasing bone mineral density (BMD), and reducing fractures. But few studies focus on the effects of Denosumab on lumbar fusion. In this study, we include osteoporotic patients with lumbar degenerative disease who have had lumbar interbody fusion surgery. The patients were randomized to either treatment of Denosumab or no treatment. All these patients are followed at 3, 6, 9, 12 months postoperation. During these periods, we detect bone metabolism and bone fusion of these patients. Finally, we would report whether Denosumab can improve bone metabolism and promote bone fusion or not.
This project aims to investigate any difference of insertional torque strength for osteoporotic patients with preoperative 1-month teriparatide injections versus those without. The increased insertional torque of pedicle screws during surgery after only 1 month of teriparatide use has also been studied. However, the effect of teriparatide on vertebral body bone mineral density (BMD) prior to and after fusion surgery has not been studied. The effects on screw insertional torque has also not been studied via a randomized controlled trial method.
The hypotheses of this study are as follows: 1. There is no significant muscle activity difference of each muscle in patients between pre and post operation. 2. There is no significant forward reach distance/average velocity difference in patients between pre and post operation. 3. There is no significant standard deviation of center of pressure (COP) along x axis, speed of COP along y axis during the task and COP path during the 3-sec holding phase difference in patients between pre and post operation. 4. There is no significant muscle activity difference between muscles on both sides at post operation.
