Objective: Lumbar Degenerative Disc Disease is a potential cause of spinal instability. Surgical techniques such as arthrodesis or arthroplasty are implemented to restore the stability to the spine. Both a fusion and a disc replacement are substantially invasive. A lumbar disk replacement is typically done via retroperitoneal or Trans peritoneal approach. With increasing number of symptomatic levels, the disk replacement becomes incrementally more invasive, with a potential for a significant blood loss, injury to great vessels, injury to abdominal viscera, weakening of abdominal wall, etc. There is no minimally invasive way to perform a disk replacement either at one or multiple levels. Our goal was to evaluate the feasibility of a novel and less invasive total nucleus replacement using magnetic spherical beads in a cadaver-based multidirectional bending flexibility model. We aimed to assess the ability of the beads to restore stability to a spine segment. We hypothesized that the beads would increase stability during flexion and extension motions. Methods: Three fresh-frozen, human cadaveric L2-L3 segments were used. We performed multidirectional flexibility tests in six directions, under intact, nucleotomy and bead insertion conditions. We measured the ranges of motions, the neutral zone and the elastic zone. Results: There was statistically significantly more flexion-extension range of motion, neutral zone and elastic zone observed upon nucleotomy than during intact condition. Bead insertion statistically significantly reduced the neutral zone observed after nucleotomy, during flexion and extension loading. Conclusion: We conclude that our novel total nucleus replacement is capable of restoring the stability to spine motion segments during flexion and extension motions, by means of adjustments to their neutral zones.

Study background: Adjacent segment disease (ASD) is a common phenomenon seen in patients who have undergone prior lumbar fusion surgery is characterized by degeneration and/or stenosis. Treatment for ASD includes extension of the fusion with a posterior approach, with direct decompression of the neural elements when indicated. Methods: 54 patients of spondylolisthesis involving L4/5 level were included in this study that were operated from January 2012 to December 2020 in Bangabandhu Sheikh Mujib Medical University and few private hospital in Dhaka who failed to respond in conservative treatment. 30 patients were male and 24 were female. patients were evaluated by clinical finding (low back pain, sensory, motor and jerks) VAS score, ODI score, JOA score, modified Macnab’s criteria, claudication distance, X-ray lumbosacral spine AP and lateral view, MRI of lumbosacral spine, CT scan of lumbosacral spine. P value of less than 0.05 was level significance. Results: Mean (± SD) age of the patients was 56.29 ± 8.13 with highest age being 68 years and lowest being 41 years. 40 were male and 24 were female. Preoperative VAS score (for both back pain and leg pain) was 6.86 ± 0.65 which significantly reduced to 1.04 ± 0.19 36 months after operation. Out of 64 patients, 62 patients showed interbody fusion with good trabecular marking. Postoperative MRI of lumbosacral spine at 36 months showed 48 patients out of 64 had no desiccation of L3/4 disc, 9 had mild disc desiccation and 7 developed desiccation of L3/4 disc. Final outcome was determined by Modified Macnab’s criteria. Excellent result found in 39 patients, good result found in 22 patients and fair result found in 3 patients. Conclusion: Fixation of L4, L5 along with S1 in single level PLIF or TLIF in L4/5 level significantly reduce the rate of disc degeneration at L5/S1 level with slight degeneration at L3/4 level.

Editorial The elements of bone(s) are (I) mechanical help of delicate tissues, (ii) switches for muscle activity, (iii) security of the focal sensory system, (iv) arrival of calcium and different particles for the upkeep of a consistent ionic climate in the extracellular liquid, and (v) lodging and backing of hemopoiesis. The design and measure of bone, both at the plainly visible and minute level, are dictated by the hereditary outline and by administrative components that assist convey with trip bone capacities. Hereditary data is liable for the profoundly preserved anatomical state of bones and doubtlessly for reestablishing that shape after break. To achieve its capacities, bone goes through persistent decimation, called resorption, completed by osteoclasts, and development by osteoblasts. In the grown-up skeleton, the two cycles are in equilibrium, keeping a steady, homeostatically controlled measure of bone. This reality, just as the histological perception that osteoclastic bone resorption is trailed by osteoblastic bone development, prompted the idea that the two cycles are unthinkingly "coupled" and to the quest for "coupling factors." No single factor has been demonstrated to connect the two cycles. Existing proof recommends that various factors presumably are engaged with the upkeep of bone homeostasis. Development factors found in bone, for example, IGFs or TGFβs, were proposed to be delivered during resorption and start neighborhood bone arrangement. Elements saved on the bone surface by osteoclasts toward the finish of the resorption stage were proposed to start the bone development that follows. Humoral components, for example, parathyroid chemical and prostaglandin E, that animate both bone resorption and bone development, could expand the two cycles couple. The activity of these components and different chemicals and cytokines on osteoclasts was proposed to be interceded by osteoblast-genealogy
