title: FACTORS ASSOCIATED WITH INFECTIONS IN SPINAL SURGERY

description: ABSTRACT Objective: To identify the factors associated with postoperative infections in spinal surgery. Methods: Descriptive, retrospective, cross-sectional study conducted in the spine surgery department of the Medical Unit of High Specialty (UMAE) at the Hospital of Traumatology and Orthopedics Lomas Verdes, Mexican Institute of Social Security (IMSS) between January 01, 2013 and June 30, 2014 through medical records of the service and the records of clinical care. Data were gathered in accordance with the records of patients with infection after spinal surgery. The factors considered were age group, etiologic agent, surgical site, type of treatment, bleeding volume and pharmacotherapy. Frequency and descriptive statistic was conducted. The rank sum test with the Wilcoxon test for a single sample was performed in different measurements; Pearson's correlation was calculated and all p&lt;0.05 values were considered significant. Results: The sample was composed of 14 patients of which 11 were female (78.6%) and 3 male (21.4%) with predominance of surgical area in the lumbar and dorsolumbar region. There was a significant correlation between the surgical time and the amount of bleeding with p&lt;0.001. Conclusions: It was clear that the infections present in patients after spinal surgery are multifactorial. However, in this study the correlation between time of surgery and bleeding amount had the highest importance and relevance.

title: PERCUTANEOUS DISCECTOMY: A CURRENT TREATMENT FOR LUMBAR DISC HERNIATION

description: ABSTRACT Objective: Describe the functional outcomes of patients with contained lumbar disc herniation (L4-L5, L5-S1) treated with manual percutaneous nucleotomy (MPN) and demonstrate that it remains a technique with good results. Methods: A prospective, longitudinal study with 110 patients contained with lumbar disc herniation (LDH) treated with (MPN). The evaluation was pre-surgical and 4, 30, 180 and 365 days after the surgery. We used Numeric Pain Scale (NPS), Oswestry Disability Index (ODI) and Macnab criteria. Descriptive and inferential statistics for differences. Results: N=110: 58 (52.72%) men, 52 (47.27%) women; average age 37.95 years (14-56) ± 10.60; most affected level: L4-L5 in 63 (57.14%) patients. NPS preoperative average: 7.75 (5-9) ± 1.12, and at 365 days: 2.14 (0-7) ± 2.37. The mean preoperative ODI was 37% (28%-40%) + 3.06, and at 365 days 9.52% (0%-40%) + 13.92. The prognosis (ODI) was good to 79 (71.81%) patients at 365 days, regular in 26 (23.63%) and poor in 5 (4.57%), corresponding respectively to patients with no, mild, moderate and severe disability. The Macnab criteria showed similar results (p = 0.00, 95% CI 0.00 to 0.13 - Student's t). Conclusions: The results were good at one-year follow-up (p = 0.00), demonstrating that the MPN is still a good option for lumbosciatic pain relief.

title: EVALUATION OF PROGNOSTIC FACTORS IN QUALITY OF LIFE OF PATIENTS WITH ADOLESCENT IDIOPATHIC SCOLIOSIS UNDERGOING SPINAL FUSION BY THE POSTERIOR APPROACH

description: ABSTRACT Objective: To evaluate the prognostic factors in the treatment of patients diagnosed with adolescent idiopathic scoliosis undergoing spinal fusion by the posterior approach. Methods: The study included 48 patients with idiopathic adolescent scoliosis (43 females and 5 males) who underwent spinal fusion by the posterior approach, with an average age at diagnosis of 12 years, and clinical signs of Risser between 3 and 4 at the time of surgery. Clinical and radiographic measurements were performed, the participants answered the SRS-30 questionnaire, and the analysis of the medical record data was performed in two occasions during the preoperative period and at the end of two years of follow-up. Results: All satisfaction measures showed statistically significant change after the procedure (p&lt;0.05) with respect to the radiographic characteristics, except for the lumbar apical vertebral translation (p=0.540) and Cobb L1-L5 (p=0.225). Conclusion: In general, it was found that patients who received surgical treatment were more satisfied with their appearance than those who underwent conservative treatment.

title: SPINE GUNSHOT WOUNDS AT THE CENTRAL MILITARY HOSPITAL IN MEXICO

description: ABSTRACT Objective: To compare the measurement of the Cobb angle in printed radiographs and digitalized radiographs displayed with the "PixViewer" tool. Methods: Pre-operative radiographs of 23 patients were performed in printed films and using the software "PixViewer". The same evaluator, a spine surgeon, chose the proximal and distal end vertebrae at the limit of the main curve in printed radiographs without identifying patients, and measured the Cobb angle based on these parameters. The same parameters and measurements were performed in digitalized radiographs. The measurements were compared, as well as the choice of end vertebrae. Results: The average change in the Cobb angle between the methods was 1.48±1.73°. The intraclass correlation coefficient (ICC) was 0.99, demonstrating excellent reproducibility. Conclusion: The Cobb method can be used to evaluate scoliosis through the "PixViewer" tool with the same reliability of the classic method on printed radiographs.

title: EVALUATION OF THE RESULTS OF THE USE OF VEPTR IN PATIENTS WITH SCOLIOSIS

description: ABSTRACT Objective: Evaluation of the results of the use of VEPTR (Vertical Expandable Prosthetic Titanium Rib - Synthes Spine Co.(r), West Chester, Pennsylvania, USA) as an option in spinal instrumentation without fusion in younger children with scoliosis, considering the complications inherent to spinal fusion in this age group. Methods: Sixteen (16) patients with scoliosis, regardless of etiology, with a mean age of 5.2 (3-8) years, were followed up by Spine Surgery Group at Hospital Getúlio Vargas, Recite-PE, and were submitted to surgical correction of the deformity using VEPTR, from April/2009 to July/2014. The survey was conducted through medical register review, and photographic and radiographic records, with the measurement of pre- and postoperative curves by the Cobb method. Results: The mean values of Cobb angle in the preoperative period, in the immediate postoperative period and after the last distraction were, respectively, 84.1° (112°-60°), 55.4° (92°-16°) and 64.4° (100°-16°), with an average initial correction of 28.7° (34.1%) and final correction of 19.7° (23.4%). The mean follow-up was 23.1 (0-61) months with an average distraction of 3.1 (0-8). The complication rate in this study was 62.5%. Conclusion: The VEPTR presented considerable correction rates of scoliosis curves in patients whose age contraindicate the spinal fusion methods. It is necessary to improve the technique and the implant itself in order to reduce complication rates, which can be considered relatively high, in addition to the conduction of more studies with longer follow-up to determine the actual efficacy of the implant and the maintenance of long-term correction.

title: SPINAL DEFORMITIES AFTER SELECTIVE DORSAL RHIZOTOMY

description: ABSTRACT Objective: Selective dorsal rhizotomy (SDR) used for spasticity treatment could worsen or develop spinal deformities. Our goal is to describe spinal deformities seen in patients with cerebral palsy (CP) after being treated by SDR. Methods: Retrospective study of patients operated on (SDR) between January/1999 and June/2012. Inclusion criteria: spinal Rx before SDR surgery, spinography, and assessment at follow-up. We evaluated several factors emphasizing level and type of SDR approach, spinal deformity and its treatment, final Risser, and follow-up duration. Results: We found 7 patients (6 males): mean age at SDR 7.56 years (4.08-11.16). Mean follow-up: 6.64 years (2.16-13), final age: 14.32 years (7.5-19). No patient had previous deformity. GMFCS: 2 patients level IV, 2 level III, 3 level II. Initial walking status: 2 community walkers, 2 household walkers, 2 functional walkers, 1 not ambulant, at the follow-up, 3 patients improved, and 4 kept their status. We found 4 TL/L laminotomies, 2 L/LS laminectomies, and 1 thoracic laminectomy. Six spinal deformities were observed: 2 sagittal, 3 mixed, and 1 scoliosis. There was no association among the type of deformity, final gait status, topographic type, GMFCS, age, or SDR approach. Three patients had surgery indication for spinal deformity at skeletal maturity, while those patients with smaller deformities were still immature (Risser 0 to 2/3) although with progressive curves. Conclusions: After SDR, patients should be periodically evaluated until they reach Risser 5. The development of a deformity does not compromise functional results but adds morbidity because it may require surgical treatment.

title: LOSS OF CORRECTION AFTER VERTEBRECTOMY FOR TREATMENT OF SPINAL DEFORMITIES

description: ABSTRACT Objective: To evaluate the loss of correction after treatment of spine deformities with the technique of isolated posterior vertebrectomy. Methods: Twenty-one patients were followed-up for three years after surgery with panoramic X-rays, CT scans, SF-36 and Oswestry questionnaires. We evaluated the loss of correction, CAGE subsidence and the evolution of the pelvis-T1 angle during follow-up. The correlation among the radiographic changes and functional and quality of life scores was also assessed. Results: All patients had some degree of loss of correction and subsidence of CAGE, especially in the first year of follow-up. Such losses exerted negative impact on the function, pain and self-image of the patients. Factors such as the stiffness of the fusion mass and size of implant used appear to have contributed to the occurrence of subsidence, regardless of age and bone mineral density. Conclusions: The use of spacers with larger cross-sectional diameter and more rigid rods can reduce the overloading on the anterior column of Denis, reducing the subsidence and loss of correction. Additional stabilization strategies such as the use of orthoses postoperatively can also be useful, and should be evaluated in subsequent studies.

title: POSTURAL PROFILE OF CLASSICAL BALLERINAS FROM THE VALE DO SÃO FRANCISCO REGION OF BRAZIL

description: ABSTRACT Objective: The study aimed to determine the association between postural changes and practice of classical ballet among ballerinas from Integrated Administrative Region of Development (RIDE) in Polo Petrolina/PE and Juazeiro/BA. Methods: Cross-sectional observational study with 19 classical ballerinas aged over 15 years and at least 5 years of uninterrupted classical ballet practice. The anthropometric assessment included measurements of total body mass, height and body mass index (BMI). Postural evaluation was performed using the photogrammetric method with help of Posturograma(r) and SAPO(c) software. Results: The mean age was 25.3±11.7 years and the mean BMI was 21.4±2.9 kg/m². Approximately 74% of classical ballerinas had normal anthropometric profile. The postural profile of the classical ballerinas showed inclination and protrusion of the head, trunk rotation, rectification of cervical lordosis, increased thoracic kyphosis, increased lumbar lordosis, pelvic inclination and anteversion. Conclusion: The practice of ballet led to changes in body alignment of the classical ballerinas evaluated. The results points out to the need of postural re-education in order to contribute for the kinetic-functional balance of classical ballet practitioners.
