title: TRUNK MOBILITY AFTER MINIMALLY INVASIVE ONE-LEVEL LUMBAR INSTRUMENTATION

description: ABSTRACT Objective: To evaluate the impact of a minimally invasive lumbar one-level fixation on trunk mobility and quality of life compared with the preoperative condition in 26 consecutive patients. Methods: The following data were collected preoperatively and postoperatively for the statistical analysis: maximal trunk extension and flexion angles, Visual Analog Scale of pain and Oswestry Disability Index scores. Results: There was improvement in all variables. Statistical significance was observed in trunk extension, pain, and Oswestry Disability Index. Although mobility in trunk flexion was higher in average values after surgery, this difference was not statistically demonstrated. Conclusion: Minimally invasive one-level lumbar fixation does not cause reduction of trunk flexibility in comparison to the mobility before surgery.

title: CHANGES IN THE SAGITTAL BALANCE IN CONGENITAL SCOLIOSIS CORRECTION SURGERY

description: ABSTRACT Objective: This study aimed to determine whether surgery leads to changes in sagittal balance in patients with congenital scoliosis. Methods: We retrospectively reviewed all cases of scoliosis operated in a tertiary hospital between January 2009 and January 2013. In all cases the deformity in the coronal and sagittal planes, kyphosis, and lordosis were measured, using the Cobb method, and spinopelvic parameters: pelvic incidence (PI), sacral slope (SS), and pelvic tilt (PT). Results A hundred and eleven medical records were analyzed, but the sample resulted in 10 patients, six of whom were females (60%). The average age was 13.4 years. In the comparative analysis between pre and postoperative, only the coronal deformity (12.37; CI 95% [7.88-16.86]; p&lt;0.001), the sagittal deformity (12.71; CI 95% [4.21-21.22]; p=0.011), and the lumbar lordosis (9.9; CI 95% [0.38-19.42]; p=0.043) showed significant change. Conclusion: There was no change in the spinopelvic parameters of patients with congenital scoliosis undergoing surgery at IOF-FMUSP between 2009 and 2013; however, it was observed decrease in lumbar lordosis, and deformity angle in the sagittal and coronal planes.

title: RELATIONSHIP BETWEEN FUNCTION AND PRESENCE AND TYPE OF DEFORMITY IN PATIENTS WITH CEREBRAL PALSY

description: ABSTRACT Objective: To evaluate the gross motor function (GMFCS) with respect to the prevalence and type of scoliosis in patients with cerebral palsy (CP). Methods: This was an analytical, cross-sectional study. We evaluated medical records and imaging studies of 100 patients randomly assigned to a specialist rehabilitation center for the care of such patients. The patients were classified according the gross motor function (GMFCS) and those with deformities were classified as per the kind of scoliosis through the classification of Lonstein and Akbarnia). A correlation was made among the presence of deformity, the variables of the type of deformity and motor function by GMFCS. Results: Of the 100 patients evaluated, 69 had scoliosis. The mean age of patients with scoliosis was higher than that of patients without deformity (12.63 and 10.46 years). Thirty-nine (57%) patients had spastic tetraparesis and 32 (46%) spastic diparesis. The most frequent curve pattern was the thoracolumbar and the average angular value of the main curve was 27 degrees. There was a positive correlation between the presence of scoliosis and GMFCS level V. There was also a positive correlation between the Lonstein Group II and GMFCS V. Conclusion: There is a positive correlation between the presence of scoliosis and greater involvement of gross motor function (GMFCS V). In patients with deformities, there is also a positive correlation between the Group II of Lonstein and GMFCS V.

title: REPRODUCIBILITY AND EQUIVALENCE OF COBBMETER APPLICATION IN THE SAGITTAL EVALUATION OF THE SPINE

description: ABSTRACT Objective: This study aims to evaluate the reliability and equivalency of using the Cobbmeter application for iPhone compared to the manual measurement method in the analysis of the sagittal spinal alignment. Methods: Cross-sectional, prospective, single-center study that had 20 panoramic radiographs of the spine in lateral view, in a neutral standing position, analyzed blindly and randomly by three independent examiners in three different times. The parameters were pelvic incidence (PI), pelvic tilt (PT) and lumbar lordosis (LL). The statistical analysis was performed to measure the intraclass correlation coefficient (ICC) between the two measurement methods, in addition to measuring the intra and inter-evaluators reliability. Results: For reproducibility analysis, the intra-evaluators ICC using the application resulted in a Kappa (K) of 0.975 for the evaluation of pelvic incidence (PI) evaluation. For pelvic tilt (PT), the K value obtained was 0.981 and the K measured for lumbar lordosis (LL) analysis was 0.987. The inter-evaluators evaluation of reproducibility using the application resulted in a K value of 0.917 for PI, 0.930 for PT and 0.951 for LL. For the assessment of equivalency of methods, comparing the application to the standard method, with a goniometer and dermographic pencil, the K value found for PI was 0.873, for PV was 0.939 and for LL was 0.914. All values were significant (p&lt;0.001) against the null hypothesis. Conclusion: This smartphone application is a valid and reliable instrument for measuring the angle involved in the sagittal balance of the spine. Furthermore, the results show that its applicability is not inferior to the manual method with goniometer and dermographic pencil.

title: CORRELATION: IMPEDANCE AND TOMOGRAPHY IN IMPLANTS INSERTION IN LUMBAR ARTHRODESIS

description: ABSTRACT Objective: To define whether the electroneurophysiological stimulation would be a safe method for reducing injuries in nerve roots during surgery of lumbar spine arthrodesis, as well as verify whether there is a direct correlation between the intraoperative impedance values and the distance from the medial cortical pedicle screw. Methods: Randomized retrospective multicenter study of 10 patients who underwent arthrodesis of lumbar spine after conservative treatment failure, with a total of 50 pedicle screws instrumented. Reliable and safe impedance values were measured in order to reduce the risk of injury to nerve roots in the perioperative period, and these values were compared with the distance between the screw and the medial cortical of the pedicle by CT scan, measured in the immediate post-operative period. Results: There is no direct correlation between the intraoperative impedance values and the distance from the screw to the medial cortical of the pedicle. Conclusion: The electroneurostimulation proved to be a reliable quantitative method to reduce the risk of injury to nerve roots during surgery of lumbar spine arthrodesis when the measured values are greater than 10mA.

title: PARAMETERS OF NUCLEAR MAGNETIC RESONANCE IN PATIENTS WITH CONGENITAL NARROWING OF THE LUMBAR SPINAL CANAL

description: ABSTRACT Objective: To compare the morphological parameters of magnetic resonance in patients with congenital narrowing of the lumbar spinal canal with patients with low back pain. Methods: A descriptive, retrospective, observational study was conducted with measurements in the axial and sagittal magnetic resonance sections of the vertebral body and canal of the lumbar spine of 64 patients with diagnosis of low back pain, which were compared with resonance images taken from 31 Mexican patients with congenital narrowing of the lumbar spinal canal. Results: The results show that patients with congenital narrowing of the lumbar spinal canal in the axial sections have a difference in diameters, being L2&lt;13.9 mm, L3&lt;13.3 mm, L4&lt;12.9 mm, L5&lt;13.1 mm, compared with controls L2&lt;20.5 mm, L3&lt;20.5 mm, L4&lt;19.3 mm, L5&lt;18.1 mm with p = 0.000. Conclusions: We found different measurements in the Mexican population compared to those found by similar studies. With the parameters obtained, it would be possible to make the proper diagnosis, surgical planning, and treatment.

title: COMPARATIVE STUDY ON THE TREATMENT OF DISC HERNIATIONS

description: ABSTRACT Objective: To compare the results of treatment of patients with low back pain and radiculalgia resulting from disc herniation associated with disc degeneration through instrumentation with pedicle screws and dynamic rod, with root release and without diskectomy compared with other non-instrumented techniques (microdiskectomy with or without foraminotomy). Methods: This is a retrospective descriptive study of interventions for patients with herniated discs in the Traumatology and Neurosurgery that used the following variables: age, sex, type of technique, surgical time, time of evolution, degree of satisfaction, and complications. Two groups were formed: instrumentation with dynamic rods and non-instrumented techniques, comparing the results of each group. The software used was the SPSS v20.0. Results: We presented 142 interventions carried out between 2009 and 2012, 86 with dynamic instrumentation and 56 by other decompression techniques without instrumentation. No statistically significant differences were observed between age and sex groups and time elapsed until intervention. We found statistically significant differences (p=0.001) in surgical time, which was lower in the instrumented technique. No significant differences were found in complications between the techniques in both re-operations and in infections. Conclusions: In this study, we found no significant differences between the use of instrumentation with dynamic rods with respect to other non-instrumented surgical techniques in the treatment of herniated discs over 6 months of evolution or the complications and the degree of the patients' satisfaction.

title: COMPLICATIONS OF NON-ENDOSCOPIC DISCECTOMY: A RETROSPECTIVE STUDY OF TWENTY-ONE YEARS

description: ABSTRACT Objective: To report and compare the number and grade of major complications presented with non-endoscopic thermal discectomy and nucleoplasty for the treatment of discogenic axial lumbar pain using laser and radiofrequency. Methods: A 21 years retrospective study was conducted of the clinical charts of patients whose reason for consultation was axial lumbar pain from degenerative disc disease, and who underwent surgery using non-endoscopic discectomy and nucleoplasty (NEDN). Two groups were established; the first, NEDN with laser, and second, NEDN with radiofrequency. The number and types of complications reported in the case-series were counted, and their statistical differences determined. Results: The inclusion criteria were fulfilled by 643 of the medical charts. 26 complications were reported, the most common being radiculitis (n=12). Statistically significant differences were found between the complications occurring in the two groups (p=0.01). Conclusion: The number of complications showed statistically significant difference. The severity of the complications and adverse outcomes provide an argument for choosing one technology over the other. Training and the learning curve stage are important factors to be taken into account, to avoid complications.
