Koomesh , 2011,
Abstract: Introduction: The use of back support is one of the common methods aimed to prevent low back pain. The purpose of the present study was to investigate the effect of wearing a lumbosacral support on lumbar spine velocity and torque in six directions during combined trunk motion. Materials and Methods : In this interventional study, 30 young healthy men were selected simply from convenient samples. They were asked to stand in Isostation B200 system and perform three-dimensional trunk motion against a resistance of 50% of maximal voluntary contraction torque while wearing or not wearing a lumbosacral support. Under each condition of test, five successive motions of trunk were performed in downward direction (as flexion, right lateral flexion, and right rotation) and upward direction (as extension, left lateral flexion, and left rotation), and the variables of average velocity and average torque were recorded during motion. Results : With the use of a lumbosacral support, average velocity was significantly increased in flexion (P=0.015) and extension (P=0.005), but no significant changes were found in other directions (P>0/05). Back support decreased average torque of right rotation significantly (P=0.006), but did not significantly changed this variable in other directions (P>0/05). Conclusion : Wearing a lumbosacral support can increase velocity in sagittal plane. Decreased rotation torque of trunk, as a result of using a back support, may reduce the twisting forces on lumbar spine joints.

Maejo International Journal of Science and Technology , 2011,
Abstract: This study presents the design and development of a prototype of lumbar support for motorcyclists corresponding to their anthropometric dimensions. The total design process model was used for this purpose. The critical design dimensions for the lumbar support (height, width, adjustable range and thickness) were obtained from the anthropometric dimensions of motorcyclists (1032 samples). The initial testing (trial runs) of the prototype proved to be successful as it was capable of providing comfort to the motorcyclists’ lumbar region during their riding process. However, further evaluation needs to be done in order to evaluate the stability, solidity, durability and safety of the prototype.

Abstract: Lumbar Disc Herniation and Lumbar Spine Stenosis are the most common spine diseases which are mainly due to age related Spine degeneration. Diagnosis of both Lumbar Disc Herniation and Lumbar Spine Stenosis depends on clinical findings as well as radiological investigations. Treatment of choice of these conditions is on the basis of the patient conditions. Surgical treatment is the option only when the conservative treatment does not improve the patient’s clinical condition. Advancement and improvement of the technology have resulted in the traditional open surgical treatment into minimal invasive surgery. Intervention of the different surgical instruments with expert spinal surgeons had made percutaneous endoscopic lumbar Spine surgery as one of the preferred choices of surgery for treating Lumbar Disc Herniation and Lumbar Spine Stenosis. The concept of percutaneous endoscopic surgery for lumbar region is to provide surgical options without producing iatrogenic morbidity associated with the open surgical procedures. Conventionally, there are different approaches/techniques for Percutaneous Endoscopic Lumbar Spine Surgery, but in this review we are mainly focusing on the Transforaminal Technique. Regarding the Lumbar Disc Herniation treatment with transforaminal approach, a number of articles have been published due to which we mainly focused on those articles which were published after 2009 onwards. While fewer articles related to Lumbar Spine Stenosis treatment with Transforaminal approach were found, we tried to brief out all those articles. On the basis of comparative study of different surgeries done for Lumbar Disc Herniation and Lumbar Spine Stenosis, Percutaneous Transforaminal endoscopic Lumbar Surgery provides a substantial benefit. Transforaminal approach for treating Lumbar Disc Herniation and Lumbar Spine Stenosis is safe and effective. The Percutaneous Transforaminal Endoscopic Lumbar Surgery has advantage as it is performed under local anesthesia with shorter length of hospitalization and early return to normal life. The clinical outcome of the patient that underwent Percutaneous Transforaminal Endoscopic Lumbar Surgery for Lumbar Disc Herniation and Lumbar Spine Stenosis is quite good in regard of its fewer complication and more benefits.

Abstract: Objective: Our study aimed at analyzing the morphometry of the lumbar spine at the CT scan and to specify its interest in spinal surgery. Methodology: This was a prospective study conducted from May 1, 2011 to July 31, 2011 in Ouagadougou. During this study, 170 patients aged 45.3 ± 12.5 years old with a sex ratio of 1.15 received a CT scan. The symptomatology was dominated by low back pain (60.6%) and lumbar osteoarthritis was the most common etiology (51.8%). The measurements were performed directly on axial and sagittal sections of the lumbar spine with measurement of the vertebral body, and pedicles. Results: The vertebral body increased forward from 24.9 mm in L1 to 26.7 mm in L5 and decreasing backwards from 26.6 mm in L1 to 23.4 mm in L5. The transverse diameter of the vertebral body ranged from 37 mm in L1 to 47.4 mm in L5 and the anteroposterior diameter of 27.6 mm in L1 to 33.5 mm in L5. The lumbar canal had an anteroposterior diameter that ranged from 15.9 mm in L1 to 15.5 mm in L5 and an interpedicular distance increasing from 21.54 mm in L1 to 28.42 mm in L5. The pedicle decreased in length from L1 (9.5 mm) to L5 (6.5 mm) while its width increased from 6.9 mm in L1 to 15.1 mm in L5. Its axis formed, with respect to the sagittal plane, an increasingly obtuse angle varying from 16.3 degrees in L1 to 29.1 degrees in L5 and with respect to the upper plate of the vertebral body, an increasingly acute angle (14, 2 degrees in L1 at 8.8 degrees in L5). Conclusion: The dimensions of the lumbar vertebrae in our series differ from those noted in Western populations in that they have a smaller vertebral body, a shorter, wider pedicle with an angle of inclination of the pedicle compared to the sagittal and horizontal planes more obtuse.

Abstract: An aggressive separation and prolonged overstretching of the paraspinal muscles in the posterior midline approach during lumbar non fusion dynamic stabilization in cases of spondylolisthesis resulting from pars interarticularis fracture may result in postoperative flat back deformity and intractable chronic pain. It is hypothesized that utilizing Wiltse paraspinal inter-muscular approach for this purpose may result in reduction of operative time, protection of integrity, vascularity, nerve supply and strength of paraspinal muscles, shortening of hospitalization and minimizing development of chronic postoperative back pain. So, I have performed this prospective descriptive study that involved 24 patients having single level lumbar instability at L4-5 or L5-S1 levels. All patients were operated upon using Wiltse minimal access posterolateral surgical technique for non-fusion dynamic stabilization. The final results revealed that males were 66%, females were 33% and ages were 42 ± 6 years. Trauma was reported in 12%. Low back pain and tenderness were reported in 100% and root affection reported in 25%. Plain X-ray and MRI were done in 100% and C.T. was done in 8% of cases. Level L4-5 was affected in 17% while level L5-S1 was affected in 83%. Anterolisthesis grades 0 was found in 8%, grades 1 in 88% and retrolisthesis in 4% of cases. Operative time was 1 hour ± 10 min., blood loss was 60 ± 20 ml., patients ambulation was after 6 - 8 hours, hospital stay was 12 - 24 hours. None of cases were complicated with infection, screw loosening, or fixation system break. Back pain VAS diminished from 7 preoperative to 5 in 2nd day, then became 4 by 1 week, 3 by 1 month and 0 by 6 months. It was concluded that utilizing Wiltse approach for posterolateral lumbar stabilization minimizes tissue damage and improves the speed of recovery and outcome.

Abstract: Introduction: Typical lumbar hernias are very rare surgical conditions. Lumbar hernias can be congenital or acquired. About 25% of all lumbar hernias have a traumatic etiology. Case-Report: We here reported a case of a 55-year-old male who was mauled by a bear. The patient developed an atypical lumbar hernia after 6 months of sustaining craniofacial and abdominal trauma. Open hernioplasty, which was a very challenging job, was done in this patient. Conclusion: Post traumatic lumbar hernias have been reported but till today no case of lumbar hernia following an attack by a bear has been reported in literature. Both acute and long-standing post-traumatic lumbar hernias are rare but challenging conditions. The corrective surgical procedure becomes more complex as hernial defect enlarges. Reconstruction is a challenging aspect of lumbar hernia surgery.

Abstract: Lumbar disc herniation is a common complaint among adults with degenerated lumbar intervertebral discs, however its incidence in childhood and adolescence is abundant. Findings recommended that pediatric lumbar disc herniation is dissimilar in numerous way from that in adults. It was confirmed that pediatric patients respond to conventional management less than adults, also the consequence of the operation continued to be acceptable for at least 10 years after the first surgery even though it seems to decline somewhat. This retrospective study was undertaken to determine the clinical outcome and the feature of lumbar disc prolapse in pediatric patients. 12 patients younger than 18 years were operated for lumbar disc prolapse in the period from 2012-2016. Patients preoperative data and radiological imaging, operative and postoperative follow up were reviewed. 12 patients were included in this study, 10 were male and 2 females, the average age was 15 years (ranging between 12 - 18 years). The average duration of the symptoms was 11 months. The average follow up was 14 months. All patients had a sciatica prior to surgery, 35% had motor deficit, and 60% had parasthesia. Conservative treatment failed in all patients. After surgery and follow up, improvement occurs in about 80% of patients, ranging from excellent to good, and 20% of patients with fair outcome. According to Pain Visual Analogue Scale, leg pain reduced from 90 - 30 and back pain from 80 - 35. Conclusion: Pediatric lumbar disc herniation is an uncommon object leading to hospitalization. About 0.1% - 0.2% of children and adolescence surgery for lumbar disc herniation in pediatric does not lead to chronic back pain or interfere with physical activity and is related to the excellent short consequence.

Abstract: Defects of the posterolateral abdominal wall of the abdomen, lumbar hernias are rare. They represent 2% to 3% of hernias of the abdominal wall. This rarity explains the large number of short series and the absence of a well-defined therapeutic modality in the publications. Grynfeltt’s hernia at the top and Jean Louis Petit’s at the bottom are the two entities. The old lumbar hernias are bulky with a rich history and easy diagnosis. Though young, they are discreet and reveal most often by their strangulation. We report the case of a Grynfeltt hernia revealed by colonic occlusion in a 77-year-old woman who had a superior right posteriolateral tumefaction for 15 years. The hernia cure was prosthetic made by the sandwich technique. No recurrence was observed after 25 months of follow-up. Through a review of the literature, we reveal the diagnostic and therapeutic difficulties.

Abstract:
As a new choice for the treatment of degenerative lumbar disease, artificial lumbar disc replacement has been widely used in clinical surgery. The finite element is a very effective method to predict and simulate the surgery effect. The purpose of this paper is to review the applications of finite element in artificial lumbar disc replacement, such as design of artificial lumbar disc prosthesis, risk and effect evaluation of artificial lumbar disc replacement, and assessment of operation methods. Lastly, we discuss the future development of finite element method applied in this field, including personalized design of the prosthesis, postoperative behavior guide, and artificial lumbar disc replacement combined with fusion surgery. In conclusion, as an invaluable complement to biomechanical experiments and clinical studies, the finite element method makes important contributions to our understanding of biomechanics of intervertebral disc, and plays an important role in the field of artificial lumbar disc replacement.
