title: NUTRITIONAL STATUS, VITAMIN D AND NASAL COLONIZATION IN SPINAL SURGERY

description: ABSTRACT Objective: Evaluate the nutritional status, vitamin D, the serum albumin, and the nasal colonization by bacteria in a Brazilian population sample that included specifically patients undergoing spine surgery Methods: The serum albumin and vitamin D tests were performed on blood samples; nasal microbiological research was performed by swab and demographic information was collected. We studied the correlation between the tests and gender and age groups of patients. Results: Seventy-five patients were included. Of this total, 74 patients underwent testing of albumin levels, 64 of vitamin D and 41 underwent nasal swab. The mean of serum albumin was 3.76 g/dl (SD = 0.53 g/dl); 70.3% of subjects were considered normal and 29.7% showed hypoalbuminemia. Regarding vitamin D, the mean was 16.64 ng/ml (SD: 7.43 ng/ml); 64.1% of patients were considered deficient, 32.8% insufficient, and 3.1% were considered normal. There was significant difference between albumin and age (p=0.007), being that the greater the age, the lower the albumin. Hypoalbuminemia was significantly more frequent over 60 years (p&lt;0.001). There was no correlation between vitamin D or nasal swab and age (p=0.603 and 0.725, respectively). The correlation between the tests and gender showed no significant difference in any of the parameters. Conclusion: The serum albumin and vitamin D levels and results of nasal swab were presented for a Brazilian sample of patients undergoing spine surgery. It was found correlation between hypoalbuminemia (inferring malnutrition) and age group of patients. Almost all the patients had some degree of vitamin D deficiency, with no correlation with age.

title: INTRASITE VANCOMYCIN POWDER AS A PROPHYLACTIC ADJUVANT IN LUMBAR FUSION

description: ABSTRACT Objective: To identify whether the use of prophylactic intrasite vancomycin as an adjuvant is a protective factor against deep tissue infection of the surgical site. Methods: Retrospective, descriptive, case-control study evaluating 210 patients, of whom 70 received intrasite vancomycin (case group) and 140 were controls. It was made a follow up for at least one year, reviewing the physical and electronic records. Data were tabulated in spreadsheets (Excel) including all variables and the statistical analysis was made with Epi InfoTM 7 to calculate the odds ratio. Results: Seven cases of deep infection occurred in the control group and none was found in the case group (odds ratio [95% confidence interval]: 0.1262 [0.007-2.24], P = 0.1585). Among the predisposing factors, diabetes and surgical time were the most relevant. Conclusions: Intrasite use of vancomycin has a protective effect against deep infection in patients undergoing lumbar fusion surgery without presenting considerable side effects.

title: LUMBAR SPINE SURGERY. IMPORTANCE OF SAGITTAL BALANCE IN THE QUALITY OF LIFE OF PATIENTS

description: ABSTRACT Objective: To evaluate whether performing surgery in degenerative diseases of the lumbar spine modify the spinopelvic balance and influences the clinical outcome and the quality of life of patients. Methods: The spinopelvic balance was evaluated in 25 patients using plain radiographs of the lumbosacral region including the proximal femur, as well as evaluating the quality of life on two separated occasions. Results: The measure of spinopelvic balance was obtained by averaging the angles of sacral slope, pelvic version and pelvic incidence. Mean preoperative angles were 59.88º, 22.84º, and 37.44º, respectively, and the mean postoperative values were 61.56º, 24.64º, and 37.32º, respectively. Regarding the questionnaires on quality of life, the Oswestry index showed mean preoperative values of 46.24, characterized as severe disability and mean postoperative values of 13.29 denoting satisfactory response after surgical treatment. The SF-36 questionnaire showed important and significant improvement in quality of life in different domains, with the exception of physical limitation and social aspects, with a p-value of 0.02 and 0.025, respectively. Conclusion: Patients undergoing surgical treatment of degenerative lumbar diseases showed no significant changes in the spinopelvic balance, but showed significant improvement in quality of life after surgery.

title: MUSCLE DISORDERS IN ADOLESCENT IDIOPATHIC SCOLIOSIS: LITERATURE REVIEW

description: ABSTRACT Scoliosis is characterized by three-dimensional changes of the spine and is estimated to be present in 4% of the population worldwide. The most common form is the adolescent idiopathic. The purpose of this study is to identify the major muscle abnormalities found in patients with adolescent idiopathic scoliosis through a literature review. We conducted an electronic search of the national databases PubMed, Lilacs, PEDro, and EMBASE using the keywords "scoliosis", "biomechanics", "exercise", "physical therapy specialty", "idiopathic", and "muscles", from January 2003 to April 2015. The most relevant articles in English, Portuguese and Spanish were selected by title and abstract. It was also performed a manual search of the references of the selected articles. From a total of 4,319 articles, 11 were selected. We conclude that individuals with AIS have changes in the paraspinal muscles, with a difference in activation between the concave and convex sides, suggesting an increase in EMG activity on the convex side, although there is still no consensus among the authors.

title: RESULTS OF TREATMENT OF CERVICAL DISCOPATHY WITH PEEK INTERBODY CAGES AT THREE LEVELS WITHOUT PLATE FIXATION

description: ABSTRACT Objective: To present the results of treatment of patients with cervical discopathy by anterior cervical approach, discectomy and placement of a PEEK interbody cage without anterior plate fixation. Methods: Retrospective, cross-sectional study from March 2013 to March 2015. Sixteen patients with radiculopathy or clinical signs of myelopathy were included; all patients underwent cervical surgery through anterior approach, discectomy, and placement of PEEK cages on three levels. Decompression levels were determined according to the correlation between preoperative radiological and clinical findings. Results: Sixteen patients predominantly male were included, with mean age of 50 years at the onset of the condition. Ten patients had involvement of C4-C5, C5-C6, C6-C7 levels, and six patients C3-C4, C4-C5 and C5-C6. Fourteen patients had cervicobrachialgia and two myelopathy. The preoperative visual analog scale average was 8/10 and the average postoperative value at 6 months was 3/10. At 6 months, there was no radiological evidence of recurrence. One patient had non-fatal complications. Conclusions: The treatment of cervical discopathy by anterior approach with interbody fusion with PEEK cage on three levels, with no plate fixation seemed to be safe and effective with better long-term results in terms of pain and myelopathy. The clinical results compare favorably with other similar series and, most importantly, the complications associated with anterior fixation plate are avoided.

title: EVALUATION OF THE DIAMETER OF THE LUMBAR VERTEBRAL CANAL USING COMPUTED TOMOGRAPHY IN MEXICAN POPULATION

description: ABSTRACT Objective: To conduct a descriptive study to find measures of central tendency in the vertebral bodies L3, L4, and L5 in the Mexican population. Methods: Fifty patients were considered, 33 male and 17 female, aged between 30 and 55 years. Measurements were performed at the levels L3, L4 and L5 taking the interpedicular distance (A), mid-sagittal diameter (B), anteroposterior distance (AP) and the depth of lateral recess (R) in axial 2-mm sections of CT scans (Somaton Emotion, SIEMENS, 2 sections) in a Mexican population with healthy vertebral bodies, with no history of lumbar pathology. Results: Overall, the measures obtained were mean interpedicular distance of 22.80 in L3, range of 16.34/28.72. In L4, mean of 23.83, range of 17.62/27.92. In L5, mean of 25.28, range of 21.88/31.29. Conclusions: This study managed to make a database that did not exist in Mexico, using measures of central tendency. Therefore, it opens the way for it to be possible, in future studies, to identify predictive factors or even developing implants.

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.
