RESUMO

OBJECTIVE: To use magnetic resonance imaging to assess the prevalence of foot and ankle ligament injuries and fractures associated with ankle sprain and not diagnosed by x-ray. METHODS: We included 180 consecutive patients with a history of ankle sprain, assessed at a primary care service in a 12-month period. Magnetic resonance imaging findings were recorded and described. RESULTS: Approximately 92% of patients had some type of injury shown on the magnetic resonance imaging. We found 379 ligament injuries, 9 osteochondral injuries, 19 tendinous injuries and 51 fractures. Only 14 magnetic resonance imaging tests (7.8%) did not show any sort of injury. We observed a positive relation between injuries of the lateral complex, syndesmosis and medial ligaments. However, there was a negative correlation between ankle ligament injuries and midfoot injuries. CONCLUSION: There was a high rate of injuries secondary to ankle sprains. We found correlation between lateral ligament injuries and syndesmosis and deltoid injuries. We did not observe a relation between deltoid and syndesmosis injuries or between lateral ligamentous and subtalar injuries. Similarly, no relation was found between ankle and midfoot injuries.

RESUMO

OBJECTIVE: To compare analgesia and opioid consumption for patients undergoing primary total hip arthroplasty with preoperative posterior quadratus lumborum block with patients who did not receive quadratus lumborum block. METHODS: The medical records of patients undergoing unilateral total hip arthroplasty between January 1st, 2017 and March 31, 2018 were reviewed, and 238 patients were included in the study. The primary outcome was postoperative opioid consumption in the first 24 postoperative hours. Secondary outcomes were intraoperative, post anesthesia care unit, and 48-hour opioid consumption, postoperative pain Visual Analog Scale scores, and post-anesthesia care unit length of stay. Primary and secondary endpoint data were compared between patients undergoing primary total hip arthroplasty with preoperative posterior quadratus lumborum block with patients who did not receive quadratus lumborum block. RESULTS: For the patients who received quadratus lumborum block, the 24-hour total oral morphine equivalent (milligram) requirements were lower (53.82mg±37.41), compared to the patients who did not receive quadratus lumborum block (77.59mL±58.42), with p=0.0011. Opioid requirements were consistently lower for the patients who received quadratus lumborum block at each additional assessment time point up to 48 hours. Pain Visual Analog Scale scores were lower up to 12 hours after surgery for the patients who received a posterior quadratus lumborum block, and the post-anesthesia care unit length of stay was shorter for the patients who received quadratus lumborum block. CONCLUSION: Preoperative posterior quadratus lumborum block for primary total hip arthroplasty is associated with decreased opioid requirements up to 48 hours, decreased Visual Analog Scale pain scores up to 12 hours, and shorter post-anesthesia care unit length of stay. Level of evidence: III.

RESUMO

Rotator cuff tears (RCT) is a multifactorial disease with genetic factors contributing for the disease etiology. We hypothesized that genetic variants in genes involved in extracellular matrix (ECM) homeostasis may alter susceptibility to RCT. We evaluated 20 polymorphisms of genes involved in ECM homeostasis in 211 cases of full-thickness tears of the supraspinatus (Nfemales = 130; Nmales = 81) and 567 age-matched controls (Nfemales = 317; Nmales = 250). Multivariate logistic regressions were carried out with age, gender, genetic ancestry (based on the analysis of 61 biallelic short insertion/deletion polymorphisms), and common co-morbidities (diabetes, dyslipidemia, and smoking habits) as covariates. We observed that carriers of the rare allele of both studied variants of TGFB1, as well as their G/A (rs1800470/rs1800469) haplotype, were less susceptible to RCT (p < 0.05). In contrast, carriers of the G allele of MMP9 rs17576 (p = 0.014) or G/G haplotype (rs17576/rs17577; p < 0.001) had an increased risk for tendon tears. The presence of the T allele of MMP2 rs2285053 (p = 0.033), the T allele of MMP3 rs679620 (p = 0.024), and the TT-genotype of TIMP2 rs2277698 (p = 0.01) was associated with susceptibility to tears, especially in females. In males, the A allele of COL5A1 rs3196378 (p = 0.032) and the G allele of TGFBR1 rs1590 (p = 0.039) were independent risk factors for RCT. The C/T COL5A1 (rs3196378/rs11103544) haplotype was associated with a reduced risk of tears in males (p = 0.03). In conclusion, we identified the genetic variants associated with RCT susceptibility, thereby reinforcing the role of genes involved in the structure and homeostasis of the ECM of tendons in disease development. © 2019 Orthopedic Research Society.

RESUMO

Frozen shoulder is a condition of loss of active and passive motion as result of inflammatory contracture and fibrosis of the joint capsule. We hypothesize that genetic variants in genes involved in these processes such as genes that play a role in extracellular matrix homeostasis (collagens, glycoproteins, genes involved in TGFß signaling, and metalloproteinases and its inhibitors) may contribute to the susceptibility to frozen shoulder. We evaluated eighteen SNPs of genes involved in extracellular matrix homeostasis in 186 cases (Nfemales = 114; Nmales = 72) of frozen shoulder and 600 age-matched controls (Nfemales = 308; Nmales = 292). Multivariate logistic regressions were carried out with age, gender, genetic ancestry, and common comorbidities as covariates. Carriers of the C allele of MMP13 rs2252070 and G/G MMP9 (rs17576 A>G/rs17577 G>A) haplotype may have an increased risk of frozen shoulder (p = 0.002, OR = 1.64, 95%CI = 1.20-2.26, and p = 0.046, OR = 1.40, 95%CI = 1.01-1.95, respectively), especially in females (p = 0.005, OR = 1.91, 95%CI = 1.22-2.99, and p = 0.046, OR = 1.59, 95%CI = 1.01-2.51, respectively). In females, the G allele of MMP9 rs17576 tended to contribute to the susceptibility to the studied disease (p = 0.05, OR = 1.51, 95%CI = 0.97-2.33). In contrast, the presence of the C allele of TGFB1 rs1800470 seems to be associated with a reduced risk (p = 0.04, OR = 0.47, 95%CI = 0.23-0.96) while the GG-genotype of TGFBR1 rs1590 was associated with increased risk (p = 0.027, OR = 4.11, 95%CI = 1.17-14.38) to frozen shoulder development in males. Thus, we identified genetic variants that were independent risk factors that can aid in the risk assessment of frozen shoulder reinforcing the involvement of MMP and TGFß signaling in disease development. © 2019 Orthopaedic Research Society.

RESUMO Objetivo Comparar a analgesia e o uso de opioides em pacientes submetidos à artroplastia total do quadril primária com bloqueio pré-operatório do quadrado lombar posterior e pacientes que não receberam o bloqueio do quadrado lombar. Métodos Revisamos os prontuários de pacientes submetidos à artroplastia total do quadril unilateral entre 1º de janeiro de 2017 e 31 de março de 2018, e 238 pacientes foram incluídos no estudo. O desfecho primário foi o consumo de opioides no pós-operatório nas primeiras 24 horas. Os desfechos secundários foram consumo de opioide no intraoperatório, na sala de recuperação pós-anestésica e nas primeiras 48 horas, escores de Escala Visual Analógica de dor pós-operatória, e tempo de permanência na recuperação pós-anestésica. Os desfechos primário e secundários foram comparados entre os pacientes submetidos à artroplastia total do quadril primária com bloqueio pré-operatório do quadrado lombar posterior e aqueles que não receberam o bloqueio do quadrado lombar. Resultados Para o grupo que recebeu o bloqueio, as doses totais de morfina por via oral em 24 horas foram menores (53,82mg±37,41) em comparação ao grupo sem bloqueio (77,59mg±58,42), com p=0,0011. A utilização de opioides foi consistentemente menor para o grupo que recebeu o bloqueio em cada tempo adicional de avaliação até 48 horas. Os escores da Escala Visual Analógica até 12 horas após a cirurgia para os pacientes que receberam o bloqueio do quadrado lombar posterior e o tempo de permanência na sala de recuperação pós-anestésica foram menores para o grupo que recebeu o bloqueio. Conclusão O bloqueio anestésico do quadrado lombar posterior para artroplastia total do quadril primária está associado à diminuição do uso de opioides nas primeiras 48 horas, diminuição do escore de dor da Escala Visual Analógica em até 12 horas, e menor tempo de permanência na sala de recuperação pós-anestésica.

RESUMO

Surgical management of lower extremity malunions and acute fractures in the setting of lower extremity deformities presents a unique challenge for orthopaedic surgeons. The objective of this study was to evaluate the outcomes of using the clamshell osteotomy in patients with acute fractures involving a malunion or deformity. A retrospective review of the cases performed by various orthopaedic traumatologists at 4 different trauma centers was performed to identify cases using the clamshell osteotomy from January 2012 to January 2016. Nine clamshell osteotomy cases were identified, 4 presenting fractures in the setting of previous malunions. All osteotomies healed within 15 months (average 6.8 ± 4.4 SD). In this multicenter case series, we demonstrate that using clamshell osteotomies can result in excellent outcomes for permitting intramedullary nailing of acute fractures in patients with lower extremity deformity.

RESUMO As fraturas periprotéticas do ombro representam uma grave complicação após a substituição da articulação. Devido ao rápido aumento do número de cirurgias de artroplastia reversa no ombro, as fraturas periprótese do úmero, descritas como raras, podem aumentar no futuro próximo. Descrevemos um caso de fratura desviada do úmero abaixo do componente umeral de uma artroplastia reversa. A paciente era uma mulher de 85 anos de idade, que tinha uma artroplastia reversa do ombro há 6 anos. O tratamento cirúrgico consistiu em osteossíntese com placa, parafusos e cerclagem. Os objetivos do presente trabalho foram reportar um caso inédito na literatura brasileira, e revisar a literatura existente e as classificações da lesão.

RESUMO

PURPOSE: The aim of this study was to evaluate the feasibility of performing minimally-invasive plate osteosynthesis (MIPO) in tibial fractures using two posteromedial incisions, and to measure the distance between the plate and neurovascular structures. MATERIALS AND METHODS: We performed nine dissections of specimens that were submitted to tibial MIPO with two posteromedial incisions. One locking compression plate (LCP) of 14 to 16 holes was inserted into the submuscular tunnel in a retrograde manner. Incisions were linked to evaluate the distance between neurovascular structures and the plate. RESULTS: During the proximal incision, a blunt dissection between semitendinosus and medial gastrocnemius tendons, as well as their lateral shift, helped to protect the main local neurovascular structures. In its distal portion, the submuscular plate tunnel insertion and its direction to the proximal incision prevented direct contact and possible damage to neurovascular structures. Moreover, we obtained successful results from a patient submitted to this procedure. CONCLUSION: Posteromedial MIPO represents a safe and attractive alternative for tibial fractures, particularly if there are damaged soft tissues in the anterior and medial side, or when access to intramedullary osteosynthesis is blocked.

RESUMO

PURPOSE: The aim of our study is to show the functional outcomes and complication rates of humeral complex fractures in adults, using osteosynthesis with two bridging orthogonal submuscular plates. METHODS: The study consists of a prospective case series of 13 patients with isolated humeral complex fractures treated with two bridging orthogonal submuscular plates. Functional assessment was performed using disabilities of the arm, shoulder, and hand (DASH) score with 30 items. The age ranged from 22 to 68 years, with a mean age of 39 years. Functional assessment with DASH score was performed at the twelfth postoperative week. RESULTS: All patients presented fracture healing in the fourth postoperative month. Of the 13 patients, five (38%) had a DASH score of zero (best function possible). One patient developed neuropraxis and presented with a score of 100 (worst possible). One case developed superficial infection, which was treated with oral antibiotics and local debridement. CONCLUSIONS: This study demonstrated satisfactory functional outcome in patients with distal-third diaphyseal humeral complex fractures treated with two locked submuscular plates. The authors consider it as a safe method and an efficient alternative, especially in younger patients who require early functional recovery.

RESUMO

OBJECTIVE: Evaluate complication rates and functional outcomes of fibular neck osteotomy for posterolateral tibial plateau fractures. DESIGN: Retrospective case series. SETTING: University hospital. PATIENTS: From January 2013 to October 2014, 11 patients underwent transfibular approach for posterolateral fractures of the tibial plateau and were enrolled in the study. All patients who underwent transfibular approach were invited the return to the hospital for another clinical and imaging evaluation. INTERVENTION: Transfibular approach (fibular neck osteotomy) with open reduction and internal fixation for posterolateral fractures of the tibial plateau. MAIN OUTCOME MEASUREMENTS: Complications exclusively related to the transfibular approach: peroneal nerve palsy; knee instability; loss of reduction; nonunion and malunion of fibular osteotomy; and functional outcomes related to knee function. RESULTS: Two patients failed to follow-up and were excluded from the study. Of the 9 patients included in the study, no patients demonstrated evidence of a peroneal nerve palsy. One patient presented loss of fracture reduction and fixation of the fibular neck osteotomy, requiring revision screw fixation. There were no malunions of the fibular osteotomy. None of the patients demonstrated clinically detectable posterolateral instability of the knee following surgery. American Knee Society Score was good in 7 patients (77.8%), fair in 1 (11.1%), and poor in 1 (11.1%). American Knee Society Score/Function showed 80 points average (60-100, S.D:11). CONCLUSION: The transfibular approach for posterolateral fractures is safe and useful for visualizing posterolateral articular injury. The surgeon must gently protect the peroneal nerve during the entire procedure and fix the osteotomy with long screws to prevent loss of reduction. LEVEL OF EVIDENCE: Therapeutic level IV.

RESUMO

OBJECTIVE: To analyze knowledge of the anatomic location of the piriform fossa using a questionnaire with anatomic figures. MATERIALS AND METHODS: Participants taking AO Trauma Brasil courses were requested to complete a questionnaire containing a photograph of the superior surface and a photograph of the lateral surface of the femur and answer a question asking which of four numbered points corresponded to the piriform fossa. RESULTS: Just 4.5% of respondents correctly chose point 2 (the piriform fossa) in both images, while 75.4% of respondents chose point 4 (the trochanteric fossa) as the correct anatomic structure. The subset of 4th-year residents' answers was significantly different from those of the other subsets, with 7.5% of correct answers. CONCLUSIONS: The low rate of correct answers indicates a tendency for the respondents to be influenced by illustrations in text books or examples in scientific publications that indicate the site of the piriform fossa incorrectly. Interest in the specialty of traumatology is possibly the reason why the subset of 4th-year residents had a better- than-average rate of correct answers.

RESUMO

INTRODUCTION: Orthopedic trauma during pregnancy can cause serious complications such as premature birth, stillbirth and maternal morbidities. PRESENTATION OF CASE: We report the case of a patient at 38 weeks pregnancy who fractured the left ankle and the right fifth metatarsal after falling. Cesarean section and osteosynthesis were performed in the usual manner in the same surgical procedure. There were no postoperative complications. DISCUSSION: Pregnancy and puerperium are associated with a hypercoagulable state. The early mobilization provided by surgical treatment of the fractures reduced the risks of thromboembolic events. CONCLUSION: The approach adopted may be used as an example for future procedures done in similar situations.

RESUMO

OBJECTIVE: To propose a new system for classifying proximal humeral neck fractures, and to evaluate intra- and interobserver agreement using the Neer system that is the most commonly used in the area and the Arbeit Gemeinschaft für Osteosynthesefragen system created by an European group, and a new classification system proposed by the authors of this study. METHODS: A total of 56 patients with proximal humeral fractures were selected, and submitted to digitized simple radiography in antero-posterior shoulder and scapular profile. Radiographs were analyzed by three observers at time one, and then three and six weeks later. The kappa coefficient modified by Fleiss was used for the analysis. RESULTS: The mean intra-observer Kappa agreement index (k=0.687) of the new classification, was higher than both the Neer classification (k=0.362) and the Arbeit Gemeinschaft für Osteosynthesefragen (k=0.46). The mean interobserver Kappa agreement index (0.446) of the new classification, also had better results than both the Neer classification (k=0.063) and the Arbeit Gemeinschaft für Osteosynthesefragen (k=0.028). CONCLUSION: the new classification considering bone compression had higher results for intra- and interobserver compared to the Neer system, and the Arbeit Gemeinschaft für Osteosynthesefragen system.


OBJETIVO: Propor um novo sistema para classificação das fraturas que envolvem o colo do úmero e avaliar a concordância intra e interobservador do sistema de classificação de Neer (a mais utilizada em nosso meio), do sistema proposto pelo grupo europeu Arbeit Gemeinschaft für Osteosynthesefragen e de um novo sistema de classificação proposto pelos autores. MÉTODOS: Foram selecionados 56 pacientes com fraturas da região proximal do úmero, com radiografias simples digitalizadas nas incidências anteroposterior do ombro e perfil da escápula. Quatro observadores avaliaram as imagens radiográficas em três momentos diferentes, com intervalos de 3 semanas. Os dados foram analisados segundo o coeficiente de concordância kappa, modificado por Fleiss. RESULTADOS: O índice de concordância kappa intraobservador médio da nova classificação (k=0,687) foi superior ao da classificação de Neer (k=0,362) e da Arbeit Gemeinschaft für Osteosynthesefragen (k=0,46). O índice de concordância kappa interobservador da nova classificação (k=0,446) também apresentou um valor médio maior que o da classificação de Neer (k=0,063) e da Arbeit Gemeinschaft für Osteosynthesefragen (k=0,028). CONCLUSÃO: A nova classificação, que considera o conceito de compressão óssea, apresentou melhores resultados inter e intraobservador, em relação às classificações de Neer e Arbeit Gemeinschaft für Osteosynthesefragen.

RESUMO

CONTEXT AND OBJECTIVE: Shoulder dislocation is the most common dislocation among the large joints. The aim here was to compare the effectiveness of reduction of acute anterior shoulder dislocation with or without articular anesthesia. DESIGN AND SETTING: Prospective randomized trial conducted in Escola Paulista de Medicina, Universidade Federal de São Paulo (EPM-Unifesp). METHODS: From March 2008 to December 2009, 42 patients with shoulder dislocation were recruited. Reductions using traction-countertraction for acute anterior shoulder dislocation with and without lidocaine articular anesthesia were compared. As the primary outcome, pain was assessed through application of a visual analogue scale before reduction, and one and five minutes after the reduction maneuver was performed. Complications were also assessed. RESULTS: Forty-two patients were included: 20 in the group without analgesia (control group) and 22 in the group that received intra-articular lidocaine injection. The group that received intra-articular lidocaine had a statistically greater decrease in pain over time than shown by the control group, both in the first minute (respectively: mean 2.1 (0 to 5.0), standard deviation, SD 1.3, versus mean 4.9 (2.0 to 7.0, SD 1.5; P < 0.001) and the fifth minute (respectively: mean 1.0; 0 to 3.0; SD = 1.0 versus mean 4.0; 1.0 to 6.0; SD = 1.4; P < 0.001). There was one failure in the control group. There were no other complications in either group. CONCLUSION: Reduction of anterior shoulder dislocation using intra-articular lidocaine injection is effective, since it is safe and diminishes the pain. CLINICAL TRIAL REGISTRATION: ISRCTN27127703.

RESUMO

CONTEXT AND OBJECTIVE: Shoulder dislocation is the most common dislocation among the large joints. The aim here was to compare the effectiveness of reduction of acute anterior shoulder dislocation with or without articular anesthesia. DESIGN AND SETTING: Prospective randomized trial conducted in Escola Paulista de Medicina, Universidade Federal de São Paulo (EPM-Unifesp). METHODS: From March 2008 to December 2009, 42 patients with shoulder dislocation were recruited. Reductions using traction-countertraction for acute anterior shoulder dislocation with and without lidocaine articular anesthesia were compared. As the primary outcome, pain was assessed through application of a visual analogue scale before reduction, and one and five minutes after the reduction maneuver was performed. Complications were also assessed. RESULTS: Forty-two patients were included: 20 in the group without analgesia (control group) and 22 in the group that received intra-articular lidocaine injection. The group that received intra-articular lidocaine had a statistically greater decrease in pain over time than shown by the control group, both in the first minute (respectively: mean 2.1 (0 to 5.0), standard deviation, SD 1.3, versus mean 4.9 (2.0 to 7.0, SD 1.5; P < 0.001) and the fifth minute (respectively: mean 1.0; 0 to 3.0; SD = 1.0 versus mean 4.0; 1.0 to 6.0; SD = 1.4; P < 0.001). There was one failure in the control group. There were no other complications in either group. CONCLUSION: Reduction of anterior shoulder dislocation using intra-articular lidocaine injection is effective, since it is safe and diminishes the pain. CLINICAL TRIAL REGISTRATION: ISRCTN27127703.


CONTEXTO E OBJETIVO: A luxação do ombro é a mais frequente luxação das grandes articulações. O objetivo foi comparar a efetividade da redução da luxação anterior aguda do ombro, com ou sem anestesia articular. TIPO DE ESTUDO E LOCAL: Ensaio clínico randomizado desenvolvido na Escola Paulista de Medicina - Universidade Federal de São Paulo (EPM-Unifesp). MÉTODOS: De março de 2008 a dezembro de 2009 foram recrutados 42 pacientes com luxação anterior do ombro agudas. Foi comparada a redução de tração e contra-tração com e sem anestesia intra-articular com lidocaína. Como desfecho primário, a dor foi avaliada por meio da escala visual analógica antes da redução e um e cinco minutos após a redução do ombro. Complicações também foram avaliadas. RESULTADOS: Foram incluídos 42 pacientes: 20 no grupo sem anestesia (grupo controle) e 22 no grupo que recebeu injeção intra-articular de lidocaína. O grupo que recebeu lidocaína intra-articular teve estatisticamente menos dor no primeiro (média = 2,1; 0 a 5,0, desvio padrão, DP, de 1,3, versus média = 4,9; 2,0 a 7,0; DP = 1,5; respectivamente; P < 0,001) e no quinto minutos (média = 1,0; 0 a 3,0; DP = 1,0 versus 4,0; 1,0 a 6,0; DP = 1,4; respectivamente; P < 0,001) após a redução em comparação ao grupo controle. Houve uma falha no grupo controle. Não houve complicações adicionais em ambos os grupos. CONCLUSÃO: A redução da luxação do ombro com o uso de lidocaína intra-articular é efetiva, pois é segura e proporciona menos dor. REGISTRO DE ENSAIO CLÍNICO: ISRCTN27127703.

RESUMO

OBJETIVO: Analisar o grau de conhecimento dos profissionais que tratam essas fraturas com a técnica preconizada relacionando a haste ao ponto de entrada considerado apropriado. MÉTODOS: Foi desenvolvido um questionário no qual constavam cinco tipos de hastes e simulada uma fratura diafisária do fêmur transversa. RESULTADOS: Os pontos de entrada correspondentes à escolha do tipo de haste foram respondidos por 370 médicos ortopedistas que participaram do 41º Congresso Brasileiro de Ortopedia e Traumatologia. Constatou-se que somente 20 por cento acertaram o ponto de entrada e que não houve diferença entre os profissionais que faziam a especialidade Traumatologia e os demais. CONCLUSÃO: Concluiu-se que a maioria dos médicos que frequentaram o congresso desconhece tal fato.


OBJECTIVE: To analyze the degree of knowledge among professionals who treat fractures using the recommended technique, with regard to correlating the nail with the entry point that is considered appropriate. METHODS: A questionnaire that presented five types of nail and simulated a transverse diaphyseal fracture of the femur was developed. RESULTS: Responses regarding the entry points corresponding to choosing the type of nail were obtained from 370 orthopedists who were participating in the 41st Brazilian Congress of Orthopedics and Traumatology. It was observed that only 20 percent correctly identified the entry point and that there was no difference between the professionals within the specialty of Traumatology and the others. CONCLUSION: It was concluded that the majority of the physicians attending the congress were unaware of the entry points.
