Abstract As the popularity of minimally invasive surgery (MIS) continues to grow, novel techniques are needed to meet the demands of multisegment fixation for advanced spinal diseases. In one such example, iliac bolts are often required to anchor large fusion constructs, but MIS technical notes are missing from the literature.  A 67-yr-old female presented with a symptomatic coronal deformity: preoperative pelvic incidence = 47°, pelvic tilt = 19°, and lumbar lordosis = 29°, sagittal vertical axis = +5.4 cm with 30° of scoliosis. The operative plan included T10-ilium fusion with transforaminal interbody grafts at L2-3, L3-4, L4-5, and L5-S1. The intraoperative video is of minimally invasive placement of iliac bolts using the O-Arm Surgical Imaging System (Medtronic®). The patient consented to the procedure.  A mini-open exposure that remains above the fascial planes allows for multilevel instrumentation with appropriate decompression at the interbody segments. After the placement of the pedicle screws under image-guidance, the direction is turned to the minimally invasive iliac bolts. Following the trajectory described in the standard open approach,1 the posterior superior iliac spine (PSIS) is identified with the navigation probe, which will guide the Bovie cautery through the fascia. This opening assists in the trajectory of the navigated-awl tap toward the anterior superior iliac spine (ASIS). Next, 8.5 mm x 90 mm iliac screws were placed in the cannulated bone under navigation. After intraoperative image confirmation of screw placement, the contoured rods are threaded under the fascia. The setscrews lock the rod in position. MIS approaches obviate cross-linking the rods, rendering pelvic fixation more facile.  This technique allows for minimal dissection of the posterior pelvic soft tissue while maintaining adequate fixation.

Orthopedic fixation devices are widely used in treatment of spinal diseases. It is expected that application of dynamic stabilization confers valuable movement possibility besides its main role of load bearing. Comparative investigation between pedicle screw model rigid fixation and (B Dyne, Elaspine, Bioflex, Coflexe rivet) models dynamic fixation systems may elucidate the efficacy of each design. The goal of the present study is to evaluate the efficacy of five fixation systems mounted on L4-L5 motion segment. In this numerical study, a 3D precious model of L4, L5 and their intervertebral disc has been employed based on CT images. five fixation devices have been also implanted internally to the motion segment. Finite element method was used to evaluate stress distribution in the disc and determine the overall displacement of the segment as a measure of movement possibility. The results show that The Coflex rivet implantation can provide stability in all motions and reduce disc annulus stress at the surgical segment (L4-L5), on the other hand, Maximum stress in the disc has been observed in dynamic systems but within the safe range. The greater movement of the motion segment has been also appeared in dynamic fixations. Existence of the fixation systems reduced the stress on the intervertebral disc which might be exerted in intact cases. Use of the fixation devices can considerably reduce the load on the discs and prepare conditions for healing of the injured ones. Furthermore, dynamic modes of fixation confer possibility of movement to the motion segments in order to facilitate the spinal activities.

Background Extraforaminal lumbar interbody fusion (ELIF) surgery is a muscle-sparing approach that allows the treatment of various degenerative spinal diseases. It is technical challenging to perform the ELIF approach at the L5–S1 level because the sacral ala obstructs the view of the intervertebral disk space. Methods We reported earlier on the ELIF technique in which the intervertebral disk is targeted at an angle of 45 degrees relative to the midline. In this article we describe the technical process we developed to overcome the anatomic relation between the sacral ala and the intervertebral disk space L5–S1 that hinders the ELIF approach at this level. We then report in a retrospective analysis on the short-term clinical and radiologic outcome of 100 consecutive patients with degenerative L5–S1 pathologies who underwent ELIF surgery. Results The L5–S1 ELIF approach could be realized in all patients. The short-term clinical outcome was evaluated 5 months after surgery: 92% of the patients were satisfied with their postoperative result; 8% had a poor result. Overall, 17% of the patients presented light radicular or low back pain not influencing their daily activity, and 82% of the patients working before surgery returned to work 3 to 7 months after surgery. The radiologic outcome was documented by computed tomography at 5 months after surgery and showed fusion in 99% of the patients. Lumbar magnetic resonance imaging performed in 5 patients at 6 months after surgery revealed the integrity of the paraspinal muscles. Conclusions ELIF surgery at the L5–S1 level is technically feasible for various degenerative spinal diseases. Analysis of the clinical and radiologic data in a consecutive retrospective cohort of patients who underwent this surgical procedure showed a good short-term clinical outcome and fusion rate.

Современная медицина имеет два приоритетных направления развития. Первое направление - это создание новейших лекарственных препаратов, а также разработка вакцин против новых вирусов. Второе направление - повсеместное и поэтапное внедрение в медицину информационных технологий. С болью в спине могут столкнуться люди не только пожилого возраста, но и подростки и даже грудные дети. Боль эта может быть вызвана многими причинами: как усталостью, так и всевозможными заболеваниями, которые могли развиться со временем или быть от рождения. По данным статистики ВОЗ, 80% населения страдает клиническими проявлениями остеохондроза позвоночника. В Российской Федерации большая часть амбулаторного приема неврологов и ортопедов занимают болезни позвоночника. Зачастую эксперту сложно однозначно оценить объект по некоторому критерию, возникают сомнения и поиски усредненной оценки. Но нередко затруднения в точном определении значения возникают не из-за недостатка опыта, а как раз, наоборот, из-за интуитивного понимания размытости оценки. Излишняя точность понятия может привести к потере части наилучших альтернатив или неправильному их ранжированию, если таковое применяется. Поэтому возникает необходимость разработки все более гибких по отношению к человеческому восприятию информации методов, позволяющих учитывать неопределенность все в большем количестве измерений. Целью данной работы является изучение методов, позволяющих с большой точностью определить заболевание позвоночника по некоторым жалобам пациента. Задачами работы являются выбор методов для просчета альтернатив, выбор критериев для альтернатив, и собственно, сами расчеты по выбранным методам Modern medicine has two priority areas of development. The first direction is the creation of the latest drugs, as well as the development of vaccines against new viruses. The second direction is the widespread and gradual introduction of information technologies into medicine. Back pain can be experienced not only by the elderly, but also by adolescents and even infants. This pain can be caused by many reasons: both fatigue and all kinds of diseases that could develop over time or be from birth. According to WHO statistics, 80% of the population suffers from clinical manifestations of osteochondrosis of the spine. In the Russian Federation, most of the outpatient visits to neurologists and orthopedists are spinal diseases. It is often difficult for an expert to unambiguously evaluate an object according to some criterion; doubts arise and searches for an average assessment. But often difficulties in accurately determining the meaning arise not because of a lack of experience, but, on the contrary, because of the intuitive understanding of the fuzziness of the assessment. Excessive precision of the concept can lead to the loss of some of the best alternatives or their incorrect ranking, if applicable. Therefore, there is a need to develop more and more flexible methods in relation to human perception of information, allowing to take into account the uncertainty in more and more dimensions. The aim of this work is to study methods that allow to determine with great accuracy the disease of the spine based on some of the patient's complaints. The tasks of the work are the choice of methods for calculating alternatives, the choice of criteria for alternatives, and, in fact, the calculations themselves according to the selected methods

Object The objective of this study was to evaluate the efficacy of chronic subthalamic nucleus (STN) stimulation for alleviating pain related to Parkinson disease (PD). Methods Among 163 consecutive patients undergoing STN stimulation, 69 were identified as experiencing pain preoperatively that was related to their PD. All 69 patients suffering from pain were followed up prospectively for 12 months after surgery. All patients described the severity of their pain according to a visual analog scale (VAS) preoperatively and at 2 weeks, 6 months, and 12 months postoperatively. Pain unrelated to PD was not studied. Results Several types of pain related to PD, the categories of which were based on a modification of 2 previous classifications (Ford and Honey), can occur in such patients: 1) musculoskeletal pain, 2) dystonic pain, 3) somatic pain exacerbated by PD, 4) radicular/peripheral neuropathic pain, and 5) central pain. The overall mean VAS score was significantly decreased postoperatively by 75% and 69% at 2 weeks and 6 months, respectively (p < 0.001). The mean VAS score at 12 months was also decreased by 80%, but 6 instances of pain (3 reports of somatic back pain and 3 reports of radicular/peripheral neuropathic pain) required additional spinal surgery to alleviate the pain severity. The results were analyzed using the Wilcoxon signed-rank test and demonstrated a significant reduction in VAS scores at all follow-up assessments (p < 0.001). Musculoskeletal pain and dystonic pain were well alleviated by STN stimulation. In contrast, somatic pain exacerbated by PD and peripheral neuropathic pain originating from lumbar spinal diseases, such as spondylosis deformans and/or canal stenosis, often deteriorated postoperatively despite attenuation of the patients' motor disability. Patients with central pain were poor responders. Conclusions This study found that STN stimulation produced significant improvement of overall pain related to PD in patients with advanced PD, and the efficacy continued for at least 1 year. The present results indicate that musculoskeletal pain and dystonic pain responded well to STN stimulation, but patients with back pain (somatic pain) and radicular/peripheral neuropathic pain originating from spinal disease have a potential risk for postoperative deterioration of their pain.
