- PREVALENCE OF ACUTE DISEASES IN THE ELDERLY ASSISTED IN EMERGENCY DEPARTMENT OF ORTHOPEDICS(2014) DOTTA, Thiago de Angelis Guerra; BONADIO, Marcelo Batista; FURLANETO, Maria Elisabet; SILVA, Jorge dos Santos; LEME, Luiz Eugenio GarcezObjective: To make an analysis of the care of elderly in an Emergency Department of Orthopedics with the primary objective to know the percentage of elderly treated, their conditions of origin and level of accidental conditions, and examine possible comorbidities, evolution and mortality rate. Methods: Retrospective observational epidemiological study based on survey records of a tertiary hospital during one year (January to December 2006) Results: In the year 2006 (January to December) 12,916 calls to patients older than 60 were performed. Conclusion: Massive attendance of the elderly population was observed, however, the vast majority related to chronic problems that do not require urgent attention. Patients requiring urgent attention suffer from trauma related to falls and are between the seventh and ninth decades of life, mostly female and requiring hospitalization for longer periods.
- LEVER SIGN TEST FOR CHRONIC ACL INJURY: A COMPARISON WITH LACHMAN AND ANTERIOR DRAWER TESTS(2021) SOBRADO, Marcel Faraco; BONADIO, Marcelo Batista; RIBEIRO, Gabriel Fernandes; GIGLIO, Pedro Nogueira; HELITO, Camilo Partezani; DEMANGE, Marco KawamuraObjective: This study aims to evaluate the sensitivity and specificity of the lever sign test in patients with and without chronic Anterior Cruciate Ligament (ACL) injuries in an outpatient setting and the inter-examiner agreement of surgeons with different levels of experience. Methods: 72 consecutive patients with a history of previous knee sprains were included. The Lachman, anterior drawer, and Lever Sign tests were performed for all subjects in a randomized order by three blinded raters with different levels of experience. Sensitivity, specificity, positive predictive value, negative predictive value, and inter-rater agreement were estimated for all tests. Results: Among the 72 patients, the prevalence of ACL injuries was 54%. The lever test showed sensitivity of 64.1% (95% CI 0.47-0.78) and specificity of 100% (95% CI 0.87-1.00) for the senior examiner. For the less experienced examiner the sensitivity was 51.8% and the specificity was 93.7%. Positive predictive values (PPV) and negative predictive values (NPV) were 100% and 70.2%, respectively. Conclusion: Lever Sign test shows to be a maneuver of easy execution, with 100% specificity and 100% PPV. Moderate agreement between experienced examiners and low agreement among experienced and inexperienced examiners was found. This test may play a role as an auxiliary maneuver.
- CORRELATION BETWEEN MAGNETIC RESONANCE IMAGING AND PHYSICAL EXAM IN ASSESSMENT OF INJURIES TO POSTEROLATERAL CORNER OF THE KNEE(2014) BONADIO, Marcelo Batista; HELITO, Camilo Partezani; GURY, Lucas Archanjo; DEMANGE, Marco Kawamura; PECORA, Jose Ricardo; ANGELINI, Fabio JansonObjective: Evaluate the correlation between magnetic resonance imaging, clinical examination and intraoperative identification of posterolateral corner injuries of the knee. Methods: We compared the findings of physical examination under anesthesia and intraoperative findings as the gold standard for the posterolateral corner injury with the reports of the MRIs of patients who underwent reconstruction of the posterolateral corner. Thus, we evaluated the use of MRI for the diagnosis of lesions. Results: We found a sensitivity of 100% in lesions of the anterior cruciate ligament (ACL), 86.96% in lesions of the posterior cruciate ligament (PCL), 57.58% in lesions of the lateral collateral ligament (LCL) and 24.24 % in tendon injuries of the popliteal muscle (PMT). Conclusion: Posterolateral corner injury is difficult to visualize and interpret; therefore, MRI imaging should not be used alone for diagnosis.
- ASSESSMENT OF THE USE OF TRANEXAMIC ACID AFTER TOTAL KNEE ARTHROPLASTY(2020) LEITE, Chilan Bou Ghosson; RANZONI, Lucas Verissimo; GIGLIO, Pedro Nogueira; BONADIO, Marcelo Batista; MELO, Lucas Da Ponte; DEMANGE, Marco Kawamura; GOBBI, Riccardo GomesObjective: To evaluate the profile of blood loss and blood transfusions after the introduction of Tranexamic acid (TXA) in a tertiary university hospital in Brazil. Methods: 173 patients were retrospectively divided into two groups: the ones who received TXA and the control group. Hemoglobin levels (Hb), drain output, transfusion rates, and thromboembolic events were measured. Results: Among the patients included in this study, 82 cases received TXA. Blood transfusion occurred in 3 cases of the TXA group (3.7%), and in 27 control group cases (29.7%; p < 0.001). The average Hb decrease was 2.7 g/dl (+/- 1.39) and the median drain output was 270 mL in the TXA group. In the control group, the values were 3.41 g/dl (+/- 1.34; p < 0.001) and 460 mL (p < 0.001), respectively. Thromboembolic events occurred in 2 TXA group cases (2.4%) and in 3 control group cases (3.3%; p > 0.999). Conclusion: TXA was effective in reducing blood transfusion rates, Hb decrease, and drain output on the 1st postoperative day without increasing thromboembolic events.
- EXTRA-ARTICULAR RECONSTRUCTION ASSOCIATED WITH THE ANTERIOR CRUCIATE LIGAMENT IN BRAZIL(2019) HELITO, Camilo Partezani; AMARAL JUNIOR, Carlos do; CAMARGO, Danilo Bordini; BONADIO, Marcelo Batista; PECORA, Jose Ricardo; DEMANGE, Marco KawamuraObjective: To assess the knowledge and technical preferences of Brazilian knee surgeons in relation to the treatment of Anterior Cruciate Ligament (ACL) injuries using intra-articular reconstruction in combination with extra-articular reconstruction. Methods: A questionnaire consisting of 16 questions about intra-articular ACL reconstruction in combination with extra-articular procedures and about the Anterolateral Ligament (ALL) was applied at the 48th Brazilian Congress of Orthopedics. Results: One hundred thirty-seven surgeons answered the questionnaire. Most surgeons perform 10-30 ACL reconstructions per year, with the transtibial technique appearing as the most common. Most surgeons find some percentage of residual pivot-shift after reconstructions, but the minority performs extra-articular procedures on a routine basis. The main indications for extra-articular reconstruction are revision and profuse pivot-shift cases. Most surgeons consider the ALL a true ligament, but 46.7% with less biomechanical importance and 32.3% with greater importance in knee stability. However, 91.4% had a positive perception of the reconstruction of this structure. Conclusion: Although the preferred technique is still the transtibial procedure, combined anatomical reconstructions already make up more than 50% of cases. Extra-articular reconstructions associated with the ACL are still performed by the minority of Brazilian surgeons, but 91.4% of them report having had a positive perception with their reconstruction.
- TOMOGRAPHIC CORRELATION OF THE MAGERL TECHNIQUE FOR C1-C2 ARTHRODESIS IN RHEUMATOID ARTHRITIS(2013) MARCHESE, Luiz Roberto Delboni; BONADIO, Marcelo Batista; LETAIF, Olavo Biraghi; CRISTANTE, Alexandre Fogaca; OLIVEIRA, Reginaldo Perilo; BARROS FILHO, Tarcisio Eloy Pessoa deObjective: To use the tomographic analysis of C1 and C2 vertebrae to assess the possibility of using Magerl's technique in patients with rheumatoid arthritis. Other objectives were to obtain anatomical data for the choice of the surgical technique in general, to establish safety parameters and obtain epidemiological data of the population in question. Methods: We retrospectively reviewed the CT scans of 20 patients with rheumatoid arthritis of the Outpatient Spine Group, IOT-HCFMUSP. Data were analyzed statistically to obtain the mean values and the variance of each measurement: the length of the C2 pedicle to the C1 lateral mass, the thickness of the pedicle and the angle of attack of the screw in the isthmus of C2 to the horizontal. Results: The mean values were, respectively: right 23.08 mm and left 23.16 mm, right 6.46 mm and left 6.50 mm, right 44.50 degrees and left 44.95 degrees. Discussion: The leading screw's manufacturers have implants compatible with the anatomical measurements found in this work. Considering the wide diffusion and mastery of Magerl's technique in our country and around the world, this is a safe surgical option that provides mechanical stability. Conclusion: Magerl's technique, according to tomographic analysis, can be used in patients with rheumatoid arthritis. Levels of Evidence IV, Case Series.
- PLATEAU-PATELLA ANGLE: AN OPTION FOR ASSESSING PATELLAR HEIGHT ON PROXIMAL TIBIA OSTEOTOMY(2016) BONADIO, Marcelo Batista; TORRES, Julio Augusto do Prado; MAZZARO FILHO, Vicente; HELITO, Camilo Partezani; GOBBI, Riccardo Gomes; DEMANGE, Marco KawamuraObjective: To compare the plateau-patella angle method to the methods already established for patellar height measurement in patients undergoing high tibial osteotomy. Methods: This is a retrospective study of 13 patients undergoing medial opening tibial osteotomy. The patellar height was measured in pre and postoperative radiographs by the methods from Insall-Salvati, Caton-Deschamps, Blackburne-Peel and patella-plateau angle, as well as the tibial slope and length of the patellar tendon. Measurements were performed by two knee surgeons at two different times. Results: The mean age was 41.33 +/- 01.09 years old. The average rates of Caton-Deschamps, Blackburne-Peel, Insall-Salvati and plateau-patella angle were, respectively, 1.00; 0.89; 1.10; and 23.15 degrees preoperatively, and 0.89; 0.78; 1.11; and 20.46 degrees, postoperatively. The correlation of Caton-Deschamps, Blackburne-Pell, and Insall-Salvati indexes and plateau-patellar angle interobserver was 0.72 (p < 0.001), 0: 54 (p < 0.001), 0.65 (p < 0.001), and 0.67 (w < 0.001), respectively. Conclusion: The plateau-patella angle method undergoes changes that are correlated with changes in tibial slope after osteotomy, unlike the classical methods. This fact may lead to overestimate the reduction of patellar height after osteotomy.
- NEGATIVE-PRESSURE WOUND THERAPY IN THE TREATMENT OF COMPLEX INJURIES AFTER TOTAL KNEE ARTHROPLASTY(2017) HELITO, Camilo Partezani; BUENO, Daniel Kamura; GIGLIO, Pedro Nogueira; BONADIO, Marcelo Batista; PECORA, Jose Ricardo; DEMANGE, Marco KawamuraObjective: To present an experience with negative-pressure wound therapy (NPWT) in the treatment of surgical wounds in patients treated for infections after total knee arthroplasty (TKA) with or without dehiscence and prophylaxis in wounds considered at risk of healing problems. Methods: We prospectively evaluated patients with TKA infection with or without surgical wound dehiscence and patients with risk factors for infection or surgical wound complications treated with Pico (R) device for NPWT in addition to standard treatment of infection or dehiscence in our institution. We considered as an initial favorable outcome the resolution of the infectious process and the closure of the surgical wound dehiscences in the treated cases and the good progression of the wound without complicating events in the prophylactic cases. Results: We evaluated 10 patients who used Pico (R) in our service. All patients had a favorable outcome according to established criteria. No complications were identified regarding the use of the NPWT device. The mean follow-up of the patients after the use of the device was 10.5 months. Conclusion: The NPWT can be safely used in wound infections and complications following TKA with promising results. Long-term randomized prospective studies should be conducted to prove its effectiveness.
