Abstract in English:ABSTRACT OBJECTIVE : To evaluate quality of life, using the SF-36, in patients with adolescent idiopathic scoliosis (AIS) who un-derwent surgery for deformity correction, comparing the results in the pre-and post-operative period. METHODS : We evaluated 29 patients, 24 female, mean age 14.5 years, all patients had measurement of Cobb angle greater than 50º, and responded to the SF-36 questionnaire preope-ratively and on average two years after surgery. RESULTS : There was improvement in all eight domains studied by the SF-36 after surgical treatment, with statistically significant improvement of the domains functional capacity physical aspects, pain and general state. Vitality and mental heal-th were those with the lowest percentage of improvement postoperatively. CONCLUSION : Surgical treatment of defor-mity in all AIS improved the functional aspects assessed by the SF-36, representing, in practice, better quality of life for these patients.

Abstract in English:ABSTRACT OBJECTIVE : To evaluate the influence of the body mass index (BMI) on the functional assessment of patients who underwent revision total knee arthroplasty (RTKA). METHODS : Thirty patients who un-derwent RTKA between January 2008 and January 2012 were retrospectively assessed using the WOMAC questionnaire. The patients were divided into three groups according to the BMI ca-tegories defined by the World Health Organization (WHO): Group I with normal BMI (18-24.9 Kg/m2), with eight patients; Group II, overweight (BMI 25-29.9 Kg/m2), with 15 patients, and Group III obesity with BMI ≥ 30 Kg/m2, with seven patients. The post-ope-rative function scores obtained through the WOMAC questionnaire were compared with the BMI of each group. The statistical analysis between BMI and WOMAC scores was performed with the Spe-arman correlation test. RESULTS : The average functional WOMAC score for individuals in Group I was 16.7; in Group II it was 47.7; and in Group III it was 69.9, with a statistically significant differen-ce between groups I, II and III (p< 0.0001). CONCLUSION : Patients with BMI > 25 Kg/m2 had a worse functional evaluation through WOMAC scores when compared to patients with normal BMI after RTKA.

Abstract in English:ABSTRACT OBJECTIVE To evaluate whether nitric oxide (NO) supplementa-tion is directly related to increased muscle power in response to strength exercise training METHODS The study included 36 individuals who underwent training for eight weeks (three times per week) with weights, who were randomly divided into two groups, both receiving the same training protocol, but one group used 3g of arginine, as a precursor of NO, and the other received placebo RESULTS There was no significant difference between groups, only a significant difference for both groups between moments: before and after the training protocol CONCLUSION Oral administration of arginine asso-ciated with a training program did not increase the muscular power of individuals. Level of Evidence I, Study Type: High quality randomized trial with statistically significant diffe-rence or no statistically significant difference but narrow confidence intervals.
Abstract in English:ABSTRACT OBJECTIVE : To evaluate the prevalence of humeral retroversion and rotational mobility (RHH) in young handball practitioners and non-practitioners. METHODS : This is a cross-sectional study performed with two groups: the handball group, with 14 female students practicing handball and the control group, with 13 young participants non-practicing pitch sports. RESULTS : The handball group presented full rotational movement (FRM) hi-gher than the control group in both the dominant shoulder (p=0.001) and the non-dominant shoulder (p=0.0001). The mobility of active and passive internal rotation was significantly higher in handball players in both shoulders. The handball group presented lower internal rotation range of motion for the dominant shoulder as compared to the non-dominant shoul-der (p=0.001). CONCLUSION : Young handball practitioners, des-pite skeletally immature, showed a higher MRT than the control group. The handball group showed loss of internal rotation (medial) on the dominant shoulder as compared to the non--dominant shoulder. Level of Evidence II, Prospective Study.
Abstract in English:ABSTRACT OBJECTIVE : To verify the frequency of late radiological com-plications in spinal fixation surgeries performed without fu-sion in oncological patients METHODS : This is a retrospective analysis analysing failure in cases of non-fused vertebral fixation in an oncology reference hospital between 2009 and 2014. Failure was defined as implant loosening or bre-akage, as well as new angular or translation deformities RESULTS : One hundred and five cases were analyzed. The most common site of primary tumor was the breast and the most common place of metastasis was the thoracic spine. The average follow-up was 22.7 months. Nine cases (8%) of failure were reported, with an average time until failure of 9.5 months. The most common failure was implant loosening. No case required further surgery CONCLUSION : The occurrence of failure was not different than that reported for fused cases. The time interval until failure was higher than the median of survival of the majority (88%) of cases. Level of Evidence IV, Therapeutic Study.
Abstract in English:ABSTRACT OBJECTIVE : To assess the quality of life of knee osteoarthritis patients using the SF-36 questionnaire METHODS : Cross-sec-tional study with 93 knee osteoarthritis patients. The sample was categorized according to Ahlbӓck score. All individuals were interviewed with the SF-36 questionnaire RESULTS : The main finding of the study is related to the association of edu-cation level with the functional capacity, functional limitation and pain. Patients with higher education level had better functional capacity when they were compared to patients with basic level of education CONCLUSION : Individuals with osteoarthritis have a low perception of their quality of life in functional capacity, functional limitation and pain. There is a strong association between low level of education and low perception of quality of life. Level of Evidence IV, Clinical Case Series.
Abstract in English:ABSTRACT OBJECTIVE : To evaluate functional outcomes of patients submit-ted to proximal row carpectomy for the treatment of wrist arthri-tis METHODS : This is a retrospective study using wrist motion and grip strenght of patients diagnosed with Kienböck disease and scaphoid non-union surgically treated by this technique RESULTS : Eleven patients with 2-year follow-up were evaluated. Wrist motion (flexion, extension and ulnar deviation) and grip strength were significantly better from preoperative values. Ho-wever, no difference in radial deviation was observed in these patients CONCLUSION : Proximal row carpectomy provides an alternative option for treatment of wrist arthritis, resulting in better active range of motion and grip strength in the long run. Level of Evidence IV, Case Series.
Abstract in English:ABSTRACT OBJECTIVE : To investigate the influence of patients' age on the delay between diagnosis and surgical treatment of proximal femoral fractures METHODS : This is a retrospective study, con-ducted at a tertiary university hospital, including all patients admitted with proximal femoral fractures between March 2013 and March 2014. The participants were categorized into four groups according to age levels. The groups were compared according to demographics, comorbidities, fracture type, trau-ma circumstances, and time between diagnosis and surgical procedure RESULTS : One hundred and sixty one patients were included, 37 adults and 124 elderly. Among adults, the mean delay between diagnosis and surgical procedure was 6.4±5.3 days; among elderly the delay was 9.5±7.6 days. There was a progressive increase in the delay from the young-adults group through the elderly individuals (Kruskal-Wallis: 13.7; p=0.003) CONCLUSION : In spite of being the patients most susceptible to complications due to surgical delay, the elderly individuals pre-sented the longest delays from admission to surgical treatment. Level of Evidence III, Retrospective Study.
Abstract in English:ABSTRACT OBJECTIVE : The purpose of this study was to evaluate the performance of valgus intertrochanteric osteotomy in femoral neck non-union. METHODS : Forty-two patients with femoral neck fractures with non-union treated using Pauwels' intertrochanteric osteotomy were reviewed. Demographics, time elapsed between fracture and surgery, follow--up, osteosynthesis used, Garden's classification, limb shortening, and x-rays were evaluated. RESULTS : Twenty-two men and 20 women were reviewed. The youngest patient was 18 years old and the oldest 65 years old, with a mean age of 42.4 years (±11.2). The minimum follow-up was 2 years, with a mean of 10.2 years. The average time elapsed between initial fracture and osteotomy was 6.5 months. Twel-ve cases were neglected femoral neck fractures. Nineteen patients were classified as Garden III, and 23 patients as Garden IV. After valgus osteotomy, non-union healing was observed in 38 patients (38/42; 90.4%). Healing of thirty-seven cases of pseudoarthrosis were obtained after the first-attempt osteotomy, and one case required two operations for healing. The osteotomy failed in four cases. Conside-ring the healed osteotomies, good to excellent functional results were achieved in 80.9% (34/42) of the patients. Total hip replacement was subsequently performed in 14.2% (6/42) of the patients for unfavoura-ble outcomes (two for cutting out, two for osteonecrosis, and two for osteoarthritis). CONCLUSIONS : Valgus intertrochanteric osteotomy has a high success rate in archiving healing in femoral neck non-union with good functional results. It is a biological and effective method. Level of Evidence IV, Therapeutic Study.
Abstract in English:ABSTRACT Total hip arthroplasty (THA) is one of the most cost-effective hip surgeries among orthopedic procedures. We conducted an extensive literature review with 5,394 papers regarding survival rates after THA. We searched PubMed, Embase and the Cochrane library from January 1st, 1970 to July 31th, 2014 looking for all citations about total hip arthroplasty with a long term follow-up (longer than 10 years). The criteria were rigorous: no loss of follow-up, and follow-up more than 10 years. The authors should have known the complete history of patients (whether the patient is alive or dead). Considering the criteria, we found only 15 papers. To evaluate the relationship between follow-up and survival, a linear regression analysis was applied. Considering the papers analysed, and applying the search criteria, we obtained a mean age for the patients above 57.5 years. The chance of survival at 15 years was 57.6%, at 20 years it was 34.6% and at 25 years it is only 11.6%. The relationship between follow-up and survival was significantly linear (p <0.001). Only 11.6% of patients undergoing THA will be still alive 25 years after the surgical procedure. Level of Evidence I, Prognostic Study.
