    Resumo em Inglês:

    Objective: To determine the prevalence of low back pain in children and its relationship with gender, age, exercise practice and sedentary activities (time on TV and on computer and/or video game). Methods: We conducted a cross-sectional study with a sample of 1,461 students, being 754 males and 707 females enrolled in the 5th to 8thgrades of all five local elementary schools of urban Ourinhos, SP, Brasil, aged 10-14 years old, from whom sociodemographic data, time spent on sedentary activities such as TV and computer and/or video game were collected. We conducted a descriptive, bivariate and multivariate binary logistic regression. Results: The results showed that the prevalence of low back pain in the sample was 18.5%, being 15.5% in boys and 21.6% in girls. Low back pain was associated to the female gender, age range between 12-14 years and the habit of watching TV more than three times a week and over 3 hours per day. Conclusion: The students analyzed showed high prevalence of low back pain related to gender, age and habit of watching TV. Appropriate interventions should be implemented to reduce the occurrences of back pain in schoolchildren.Level of Evidence III, Cross Sectioning.

    Cury, Ricardo de Paula Leite; Cinagawa, Eduardo Hitoshi Tsuge; Camargo, Osmar Pedro Arbix; Honda, Emerson Kiyoshi; Klautau, Giselle Burlamaqui; Salles, Mauro José Costa

    Resumo em Inglês:

    Objectives: To identify and compare the rate of success of therapeutic modalities applied in surgeries for the treatment of infections associated with total knee arthroplasty (TKA), and to evaluate the functional outcome and pain in different therapeutic modalities by means of quality of life scores. Methods: We evaluated all patients who developed periprosthetic infection after TKA for primary or secondary osteoarthritis, in the period from January 1st, 2008 to December 31st, 2010. Results: In the study period, 29 patients with TKA had infection, and 12 of these underwent debridement and retention of the prosthesis (D+R), seven received two-stage and six one-stage exchange arthroplasties, and four patients were treated with suppressive antibiotic therapy because they could not undergo another surgical procedure. Conclusion: The D+R, one-stage revision and two-stage revision success rates were 75%, 83.3%, and 100%, respectively. The best results of quality of life (QoL) and function occur in patients undergoing D+R. In contrast, the worst QoL and functional results were obtained in patients treated with two-stage revision arthroplasty.

    Resumo em Inglês:

    Objective: To report clinical and epidemiological characteristics and risk factors of patients with Carpal Tunnel Syndrome (CTS) on sick leave admitted in a University Hospital. Methods: This is a transversal study conducted with patients admitted sequentially over 18 years of age, without distinction of gender and race in the period between September and November 2014. Patients answered a questionnaire and underwent physical examination carried out by the authors. Results: Twenty-five patients were admitted within three months, all females, the mean age was 50.24 years old (standard deviation 10,39) . Among the professions they performed, general and cleaning services were the most prevalent. Most patients featured obesity, followed by depression and systemic arterial hypertension. Approximately half of them were on sick leave. Sleep disorders were also a frequent complaint. Conclusion: CTS is a frequent cause of sick leave and it is related to obesity, dyslipidemia and depression. Level of Evidence IV, Series of Cases.

    Astur, Diego Costa; Santos, Bruno; Moraes, Eduardo Ramalho de; Arliani, Gustavo Gonçalves; Santos, Paulo Roberto Dias dos; Pochini, Alberto de Castro

    Resumo em Inglês:

    Objective: To evaluate the low energy extracorporeal shock waves therapy (ESWT) associated with physical therapy in the treatment of chronic muscle injuries classified as grades 2 and 3 in the lower limbs of amateur athletes. Methods: Eight athletes presenting with lower limb muscle injury for more than three weeks were treated with physiotherapy and ESWT. We evaluated the following parameters during treatment: palpable gap, muscle strength, pain, and Tegner score, as well as ultrasound image features and the ability to return to sports practice. Results: The average time of the first evaluation of the injury was 8.75 weeks. All patients presented muscle strength grade V after eight weeks. The pain score evolved from 5.75 to 0.5 points of the visual analogue scale (VAS), at the end of the treatment. The Tegner score after treatment was six points on average. Patients returned to sports practice after 8.14 weeks. Conclusion: ESWT associated with physical therapy proved to be effective to treat long-term muscle injury, with good performance and the ability to return to sport practice for all patients.

    Miyazaki, Alberto Naoki; Santos, Pedro Doneux; Silva, Luciana Andrade da; Sella, Guilherme do Val; Miranda, Eduardo Régis de Alencar Bona; Zampieri, Rodrigo

    Resumo em Inglês:

    Objective: To evaluate the fatty infiltration and atrophy of the supraespinatus in the pre- and postoperative of a rotator cuff lesion (RCL), by MRI. Methods: Ten patients with full-thickness rotator cuff tears who had undergone surgical arthroscopic rotator cuff repair between September and December 2011 were included. This is a prospective study, with analysis and comparison of fatty infiltration and atrophy of the supraespinatus. The occupation ratio was measured using the magic selection tool in Adobe Photoshop CS3(r) on T1 oblique sagittal Y-view MRI. Through Photoshop, the proportion occupied by the muscle belly regarding its fossae was calculated. Results: There was a statistically significant increase in the muscle ratio (p=0.013) comparing images pre and postoperative, analyzed by the Wilcoxon T test. Conclusion: The proportion of the supraspinal muscle above the pit increases in the immediate postoperative period, probably due to the traction exerted on the tendon at the time of repair.

  • KIRSCHNER WIRE VERSUS TITANIUM ELASTIC NAILS IN PEDIATRIC FEMORAL SHAFT FRACTURES Original Article

    Isik, Cengiz; Kurtulmus, Tuhan; Saglam, Necdet; Saka, Gursel; Akpinar, Fuat; Sarman, Hakan

    Resumo em Inglês:

    Objective: To evaluate the effectiveness of intramedullary fixation using the Kirschner-wire (K-wire) compared to the titanium elastic nail (TEN) in pediatric femoral shaft fractures. Methods: A sample of 42 pediatric patients with a mean age of 6.55±2.42 years (range 4-11 years) presenting femoral shaft fractures underwent intramedullary fixation using the K-wire or TEN. Results: There was no significant difference found between groups, of which 16 (38.1%) patients were treated with K-wire and 26 (61.9%) patients were treated with TEN in terms of union duration. Moreover, none of the patients showed nonunion or a delayed union. Conclusions: The use of adjusted K-wire instead of TEN in the intramedullary fixation of femoral shaft fractures in selected children may be an advantageous surgical option due to the lower cost, easy accessibility and no need for a second surgery for implant removal.

    Grzegorzewski, Andrzej; Synder, Marek; Modrzewski, Tadeusz; Drobniewski, Marek; Polguj, Michał; Sibiński, Marcin

    Resumo em Inglês:

    Objective: To evaluate the distribution of SP (substance P) and S-100 peptide immunoreactivity, as well as the vascular supply of tissues commonly used as grafts for anterior cruciate ligament (ACL) reconstruction. A second aim was to compare the above mentioned distribution in the semitendinosus muscle tendons of cerebral palsy (CP) patients with the semitendinosus muscle tendons and patellar tendons of patients without CP. Methods: The first group consisted of 14 children with cerebral palsy with a mean age of 11.7 years old. At the time of hamstring lengthening operation, a sample of semitendinosus muscle was taken for analysis. The second group comprised 20 patients treated for isolated ACL rupture of the knee (mean age 32 years old). Group three comprised ten patients in the mean age of 14.3 years old treated for recurrent lateral patellar dislocation, and from whom a sample of patellar tendon was obtained. Results: No statistically significant differences were demonstrated with regard to the amount of immunopositive nerve fibers expressing SP or S-100 in all 3 groups of patients. A significant difference was noted in the number of blood vessels between the adult and child semitendinosus muscles, but not between the semitendinosus muscles and patellar tendon of children. Conclusion: The number of nociceptors as well as proprioceptive fibers is similar in patients with CP and patients from a neurologically healthy population.Level of Evidence IV, Cases Series.
  • COMPARATIVE STUDY BETWEEN OSTEOSYNTHESIS IN CONVENTIONAL AND BIOABSORBABLE IMPLANTS IN ANKLE FRACTURES Original Article

    Gaiarsa, Guilherme Pelosini; Reis, Paulo Roberto dos; Mattar Junior, Rames; Silva, Jorge dos Santos; Fernandez, Túlio Diniz

    Resumo em Inglês:

    Objective: To compare the functional results of ankle fractures treated with metallic and absorbable plates. Twenty patients were randomized into two groups (metallic and absorbable implant groups) and followed prospectively. In the immediate postoperative period, patients were immobilized with plaster casts for one week, which was replaced by a removable cast for another four weeks. Partial weight-bearing was allowed after three weeks, and full weight-bearing after six weeks. Functional recovery was similar in both groups. At six months, three patients in the metallic group complained of local pain, and had their implants removed. One patient in the absorbable group exhibited early dehiscence of the suture and underwent debridement and suturing with good evolution. The American Orthopaedic Foot and Ankle Society (AOFAS) score was similar between the two groups after six and nine months of follow-up. The absorbable implants showed clinical and functional results that were similar to those of metallic implants. Level of Evidence II, Prospective Comparative Study.

    Schwartsmann, Carlos Roberto; Spinelli, Leandro de Freitas; Sotomayor, Marco Yánez; Yépez, Anthony Kerbes; Boschin, Leonardo Carbonera; Silva, Marcelo Faria

    Resumo em Inglês:

    Objective: To evaluate the bleeding of the femoral head on hip osteoarthritis in patients who underwent total hip arthroplasty. Methods: One hundred and three hips affected by primary hip osteoarthritis were evaluated. After surgical dislocation, the femoral head was divided into four quadrants, and micro perforations were made in order to observe and assess the presence of bleeding, as early type (EB), late type (LB) or without bleeding (WB). Results: We observed early bleeding (EB) in the upper quadrant in 16 hips (15.5%), late bleeding in 14 hips (13.6%) and no bleeding (WB) in 73 hips (70.9%). The anterior quadrant showed EB in 24 hips (23.3%), LB in 7 hips (6.8%) and WB in 72 hips (69.9%). The lower quadrant presented EB in 40 hips (38.8%), LB 14 hips (13.6%) and WB in 49 hips (47.6%). The posterior quadrant showed EB in 39 hips (37.9%), LB 19 hips (18.4%) and WB in 45 hips (43.7%). Comparing BMI and gender, we found no association between these parameters (p> 0.05). Conclusions: The inferior and posterior quadrant had the highest bleeding levels, following the path of the medial circumflex artery. Level of Evidence III, Therapeutic Study.

    Resumo em Inglês:

    Objective: To analyze the epidemiological aspects of proximal humerus fractures and describe the profile of patients with proximal humerus fractures hospitalized and treated at Hospital São Paulo, between 2008 and 2013. Methods: Hospital records were retrospectively analyzed for surgically treated patients diagnosed with proximal humerus fracture. Age, gender, injury mechanism, length of hospital stay, performed treatment and associated diseases were considered. Results: From all patients studied, 52 were female at their sixth decade of life. As for the injury mechanism, fall from height was the main cause for women (88.46%) and for man it was motorcycle accidents (31.42%). Fixation with locked plate was the most frequently used treatment. Conclusion: Most patients were female in their fifth decade of life, injured mainly by fall from height. Fixation with locked plate was the most frequently used treatment and the patients were admitted for 7 days, on average. Level of Evidence II, Retrospective Study.
