Patient Blood Management Program Implementation: Comprehensive Recommendations and Practical Strategies.

INTRODUCTION: Blood transfusion is one of the most common medical practices worldwide. However, current scientific literature has shown that the immunomodulatory effects of blood transfusion are associated with an increased likelihood of infection, prolonged hospitalization, and morbimortality. Also, it means high costs for healthcare systems. METHODS: In this context, acknowledging that blood transfusions are essentially heterologous cell transplantations, the use of therapeutic options has gained strength and is collectively known as the patient blood management (PBM) program. PBM is an approach based on three main pillars: (1) treating anemias and coagulopathies in an optimized manner, especially in the preoperative period; (2) optimizing perioperative hemostasis and the use of blood recovery systems to avoid the loss of the patient's blood; (3) anemia tolerance, with improved oxygen delivery and reduced oxygen demand, particularly in the postoperative period. RESULTS: Current scientific evidence supports the effectiveness of PBM by reducing the need for blood transfusions, decreasing associated complications, and promoting more efficient and safer blood management. Thus, PBM not only improves clinical outcomes for patients but also contributes to the economic sustainability of healthcare systems. CONCLUSION: The aim of this review was to summarize PBM strategies in a comprehensive, evidence-based approach through a systematic and structured model for PBM implementation in tertiary hospitals. The recommendations proposed herein are from researchers and experts of a high-complexity university hospital in the network of the Sistema Único de Saúde, presenting itself as a strategy that can be followed as a guideline for PBM implementation in other settings.

Quantification of First Metatarsal Joint Surface Interactions in Hallux Rigidus Using Distance and Coverage Mapping: A Case-Control Study.

BACKGROUND: Weightbearing cone-beam computed tomography (WBCT) has proven useful for analysis of structural changes of the foot and ankle when compared to conventional radiographs. WBCT allows for extraction of distance and coverage mapping metrics, which may provide novel insight into hallux rigidus (HR). This study retrospectively assessed HR joint space using distance and coverage mapping in a case-control study. METHODS: WBCT images of the foot and ankle for 20 symptomatic HR and 20 control patients were obtained. Three-dimensional models were created and analyzed using a custom semiautomatic measurement algorithm. Distance and coverage mapping metrics for the first metatarsophalangeal and metatarsosesamoid joints were extracted from the models and compared between cohorts. Relationships between these metrics and visual analog scale (VAS) scores, a patient-reported outcome of pain, were assessed in HR patients. RESULTS: Overall first metatarsophalangeal joint space narrowing was noted in HR patients when compared to controls by an average of 11.8% (P = .02). However, no significant changes in the overall coverage of the joint were noted. Decreased joint space width and increased surface-to-surface coverage were only and particularly observed at the plantar medial quadrant of the first metatarsal head in HR patients relative to controls. VAS score was significantly but weakly correlated with dorsolateral quadrant coverage (R2 = 0.26, P = .03). CONCLUSION: Distance and coverage mapping serve as a complementary option to current techniques of quantifying HR changes. These metrics can expand the scope of future work investigating joint articulation changes in HR.

Hindfoot Alignment in Flexible Cavovarus Deformity Under Orthostatic and Coleman Block Test Positions: A Weightbearing Computed Tomography Study.

BACKGROUND: Flexible cavovarus deformity is prevalent and the Coleman block test is frequently used to assess the first ray plantarflexion malpositioning in the overall deformity as well as the flexibility of the hindfoot. The objective was to assess and compare the weightbearing computed tomography (WBCT) 3-dimensional (3D) changes in clinical and bone alignment in flexible cavovarus deformity patients when performing the Coleman block test when compared to normal standing position and to controls. METHODS: Twenty patients (40 feet) with flexible cavovarus deformity and 20 volunteer controls (40 feet) with normal foot alignment underwent WBCT imaging of the foot and ankle. Cavovarus patients were assessed in normal orthostatic and Coleman block test positions. Foot and ankle offset (FAO), hindfoot alignment angle (HAA), talocalcaneal angle (TCA), subtalar vertical angle (SVA) and talonavicular coverage angle (TNCA) and a CT-simulated soft tissue envelope image, WBCT clinical hindfoot alignment angle (WBCT-CHAA), were evaluated by 2 readers. Measurements were compared between cavovarus nonstressed and stressed positions and to controls. P values of .05 or less were considered significant. RESULTS: The intra- and interobserver intraclass correlation coefficient were good or excellent for all WBCT measurements. Cavovarus patients demonstrated significant correction of WBCT-CHAA (9.7 ± 0.4 degrees), FAO (2.6 ± 0.4%), and TNCA (8.8 ± 1.8 degrees) when performing the Coleman block test (all P values <.0001). However, WBCT-CHAA and FAO measurements were still residually deformed and significantly different from controls (P values of .001 and <.0001, respectively). TNCA values corrected to values similar to healthy controls (P = .29). No differences were observed in cavovarus patients during Coleman block test for the coronal measures: HAA, TCA, and SVA measurements. CONCLUSION: In this study, we observed improvement in the overall 3D WBCT alignment (FAO), axial plane adduction deformity (TNCA), as well as CT simulated clinical hindfoot alignment (WBCT-CHAA) in flexible cavovarus deformity patients when performing a Coleman block test. However, we did not find improvement in measures of coronal alignment of the hindfoot, indicating continued varus positioning of the hindfoot in these patients. LEVEL OF EVIDENCE: Level III, retrospective comparative study.

A Case Report of Isolated Cervical Ligament Rupture With Hyper-Pronation Injury: Specific MRI Protocol and Surgical Reconstruction.

Background: The aim of this case report is to present a case of chronic cervical ligament tear and instability, which occurred by an unusual work injury with an eversion/hyper-pronation mechanism in contrast to the usual mechanism of inversion. The ligament was reconstructed using an allograft with satisfactory results up to 30 months after surgery. A new magnetic resonance imaging protocol (MRI) was developed to better evaluate the cervical ligament/graft. Conclusion: In diagnosis of foot sprains, a specific ligament injury should always be sought. In this case, physical examination producing tenderness at the location of the cervical ligament and correlating this with an oblique intercolumn stress test that reproduced pain with apprehension and gross instability supported the diagnosis. Retrospectively applying anatomic knowledge to the earlier MRI findings of bone marrow edema at the insertion points of the cervical ligament on the talus and calcaneus was important in confirming the diagnosis. To better evaluate the cervical ligament allograft tendon reconstruction, a novel volumetric MRI sequence was developed which may prove helpful to also diagnose cervical ligament injuries in future cases. Anatomic reconstruction of the cervical ligament provided satisfactory clinical and radiographic results at 30-month follow-up.Level of Evidence: V.

A Case Report of Brodie's Abscess of the Cuboid Treated by Anatomic Antibiotic-Cement Spacer.

Background: A case of chronic osteomyelitis with Brodie's abscess of the cuboid caused by a wooden foreign body penetrating the plantar foot. Total cuboidectomy was carried out with implantation of an anatomically molded antibiotic-impregnated cement spacer with culture-specific postoperative intravenous antibiotics. At six months of follow-up, the patient was completely asymptomatic without evidence of a recurrence of infection. Final radiographs also didn't show spacer migration or surrounding bone erosions. The spacer obviated the need for any foot fusion which preserved foot biomechanics. The patient didn't need to use any braces or insoles. Conclusion: Osteomyelitis should always be on the differential list of lytic lesions of the tarsal bones, especially if there is a history of prior foot trauma. In this case, cuboid excision and placement of an antibiotic-impregnated cement spacer provided sustained relief of symptoms without evidence of recurrence or complications for six months.Level of Evidence: V.

Biomechanical consequences of Zadek osteotomy in insertional achilles tendinopathy: A virtual surgical simulation study.

BACKGROUND: The Zadek osteotomy modified by Taylor (ZO) is a surgical technique used to treat insertional Achilles tendinopathy (IAT) by reducing the heel's prominence and elevating the Achilles tendon insertion. This study aims to analyze the biomechanical consequences of IAT after ZO using a virtual surgical simulation with a specific software. METHODS: A retrospective analysis of 20 wtbearing computed tomography (WBCT) scans of IAT patients was conducted. Using Disior's BonelogicTM software, 3D models were created from WBCT images. Virtual ZO was performed on these models, and various biomechanical parameters were measured before and after the virtual osteotomy. RESULTS: The virtual ZO showed significant statistical differences in the average of the calcaneal length (p < 0.001), Fowler Philips angle (p < 0.001), calcaneal pitch (p < 0.001), and the sagittal talocalcaneal angle (p < 0.001). CONCLUSIONS: The virtual ZO analysis suggests that this procedure can decrease the Fowler Philips angle, shorten the calcaneus, modifying specifically the sagittal alignment. LEVEL OF EVIDENCE: IV; case series.

Posterior Ankle Impingement: It's Not Only About the Os Trigonum.

Background: Os trigonum and Stieda process are common etiologies for posterior ankle impingement syndrome (PAIS), and diagnosis is typically made by radiographs, computed tomographic, or magnetic resonance imaging. However, these static tests may not detect associated soft tissue and bony pathologies. Posterior ankle and hindfoot arthroscopy (PAHA) is dynamic, providing at least ×8 magnification with full anatomical visualization. The primary aim of this study was to report the prevalence of associated conditions seen with trigonal impingement treated with PAHA. Methods: In this retrospective comparative study, patients who underwent PAHA for PAIS due to trigonal impingement, from January 2011 to September 2016, were reviewed. Concomitant open posterior procedures and other indications for PAHA were excluded. Demographic data were collected with pre- and postoperative diagnosis, arthroscopic findings, type of impingement, location, associated procedures, and anatomical etiologies. Trigonal impingements were divided in os trigonal or Stieda and subgrouped as isolated, with flexor hallucis longus (FHL) disorders, with FHL plus other impingement, and with other impingement lesions. Results: A total of 111 ankles were studied-74 os trigonum and 37 Stieda. Isolated trigonal disorders accounted for 15.3% of PAIS (n = 17). Cases having associated conditions had a mode of 3 additional pathologies. FHL disorders were found in 69.4%, subtalar impingement in 32.4%, posteromedial ankle synovitis in 25.2%, posterolateral ankle synovitis in 22.5%, and posterior inferior tibiofibular ligament impingement in 19.8% of cases. Associated pathologies were observed in 58.6% of cases when FHL was not considered. Significant differences were noted comparing os and Stieda (isolated: 20.3% to 5.4%, P = .040; FHL plus others: 35.1% to 59.5%, P = .015). Conclusion: Trigonal bone (os trigonum or Stieda) was found to cause impingement in isolation in a small proportion of cases even when the FHL was considered part of the same disease spectrum. This should alert surgeons when considering removing trigonal impingement. Open approaches may limit the visualization and assessment of associated posterior ankle and subtalar pathoanatomy, thus possibly overlooking concomitant causes of PAIS. Level of Evidence: Level III, retrospective comparative study.

The role of computed tomography with external rotation and dorsiflexion in decision making for acute isolated non-displaced posterior malleolar fractures Bartonícek and Rammelt type II: a prospective study.

PURPOSE: Our objective was to evaluate the syndesmotic and fracture instability using conventional ankle computed tomography (CT) with stress maneuvers. METHODS: A consecutive sample of 123 individuals with an ankle sprain was assessed for eligibility. In total, 33 patients met the inclusion criteria. All patients underwent a magnetic resonance imaging (MRI) and CT scan with stress maneuvers (CTSM). The patterns of ligament tears f were classified using West Point grades I, IIA, IIB, III. Mann-Whitney test was used to test the differences in the numerical variables between injured and uninjured syndesmoses. The Spearman correlation tested the strength of the association between the tibial joint surface involved in posterior malleolus fracture and syndesmotic instability. RESULTS: In MRI, two patterns of syndesmotic ligament injury predominated. A completely torn anterior inferior tibiofibular (AITFL) and interosseous tibiofibular ligaments (ITFL) and a completely torn AITFL were combined with a partially torn ITFL. In the neutral phase CTSM and during the stress phase the median difference of the narrowest tibiofibular distance between injured and uninjured syndesmoses was 0.2 mm (P = 0.057) and 2.3 mm (P < 0.0001), respectively. There was no association between the percentage of involvement of the posterior tibial joint surface in the posterior malleolar fracture and syndesmotic instability as measured with CTSM. CONCLUSION: The conventional computed tomography with external rotation and dorsiflexion represents a reproducible and accurate diagnostic option for detecting syndesmosis instability and fracture instability in acute isolated non-displaced posterior malleolar fractures Bartonícek and Rammelt type II. LEVEL OF EVIDENCE: Prospective study among consecutive patients (Diagnosis); Level of evidence, 2.

Changes in the methodology of medical teaching due to the COVID-19 pandemic

ABSTRACT Objective To evaluate the perceptions of students and teachers regarding remote teaching modality in comparison with the traditional face-to-face method. Methods In this observational, retrospective, comparative, single-center study, questionnaires containing three major assessment domains were sent to two groups: university professors and undergraduate and graduate students. The first domain collected demographic and general data on the platforms used. The second and third domains contained questions that compared the perception of the quality of information offered by the two systems. Results Between May and September 2020, 162 students and 71 teachers participated in the study. A greater proportion of students demonstrated previous contact with the online method, while professors had presented a greater number of courses. Most participants reported that their expectations regarding the remote teaching method were met (students, 80.3%; teachers, 94.4%). A significant number of students (83.3%) and teachers (88.7%) rated the classes as easier to attend and manage. Despite difficulties, such as concentration retention, most of the participants agree (at least partially) that the format should be maintained. Conclusion The remote teaching methodology, although still incipient in Brazil, has become a reality in light of current health restrictions. Our study demonstrated a high level of overall satisfaction and a high sense of learning from both students and faculty. However, new challenges associated with this system have been identified, such as retention of attention and interference from the external environment. Longitudinal comparative studies that incorporate various aspects of medical education in all cycles are necessary to corroborate the findings of this study. Design Retrospective comparative study, level III evidence.

Public financing versus private billing in a public hospital under management of a Social Health Organization / Financiamento público versus faturamento privado em um hospital público sob gestão de uma Organização Social de Saúde

ABSTRACT Introduction: to assess the efficiency of management by a Social Health Organization (Organização Social de Saúde - OSS) compared with the private sector; to verify if there are savings for the State Health Secretariat (SES) in management contracts for financing the production of a public hospital versus its production values billed by private methods; and to establish if the amounts billed by the Unified Health System (SUS) table would finance the same procedures. Methods: we compiled and tabulated all procedures performed and the materials and drugs dispensed in the Euryclides Jesus Zerbini Transplant Hospital (HTEJZ), managed by the OSS Associação Paulista Para o Desenvolvimento da Medicina (SPDM), in September, October, and November 2018, according to the Brasíndice® table for drugs, the Simpro® table for materials, the CBHPM® table for medical fees, and tables SIGTAP SUS and SIA SUS. We then compared the average values obtained in the private billing with the costing amount reimbursed by the State Health Secretariat and the billing calculated in the SIA-SUS. Results: the average SUS revenue was R$ 2,774,086.91; the monthly reimbursement by the SES was R$ 13,055,700.00; and the average private revenue was R$ 25,084,440.31. Conclusions: the management by the OSS SPDM in the Euryclides de Jesus Zerbini Transplant Hospital was more efficient in the financing / production ratio than it would be to a private hospital. The economy of public funds was significant. The current SUS table reimbursement values would not meet the need for funding for an overly complex hospital.

RESUMO Objetivo: os objetivos deste estudo foram verificar a eficiência da gestão por Organização Social de Saúde (OSS) comparada com o setor privado; se há economia para a Secretaria do Estado da Saúde (SES) nos contratos de gestão para custeio da produção de um hospital público frente aos valores de produção faturada pelos métodos privados e estabelecer se os valores faturados pela tabela do Sistema Único de Saúde (SUS) financiariam os mesmos procedimentos. Métodos: foram compilados e tabelados todos os procedimentos realizados, materiais e medicamentos dispensados no âmbito do Hospital de Transplantes Euryclides de Jesus Zerbini (HTEJZ) gerido pela OSS Associação Paulista para o Desenvolvimento da Medicina (SPDM), nos meses de setembro, outubro e novembro de 2018 de acordo com a tabela do Brasíndice® para medicamentos, Simpro® para materiais, CBHPM® para honorários médicos, Tabela SIGTAP-SUS e SIA-SUS; em seguida foi realizada a comparação entre os valores médios obtidos no faturamento privado, o valor de custeio repassado pela Secretaria do Estado da Saúde e o faturamento apurado no SIA-SUS. Resultados: faturamento médio SUS de R$ 2.774.086,91; repasse mensal SES R$ 13.055.700,00; faturamento privado médio de R$ 25.084.440,31. Conclusões: a gestão pela OSS SPDM no Hospital de Transplantes Euryclides de Jesus Zerbini foi mais eficiente na relação financiamento/produção do que seria para um hospital privado. Foi muito significativa a economia para o erário público. Os atuais valores de remuneração da Tabela SUS a serem repassados não atingiriam a necessidade de custeio para um hospital de alta complexidade.

Achilles Tendon Lesions - Part 1: Tendinopathies / Lesões do Aquiles - Parte 1: Tendinopatias

Abstract Calcaneal tendon injuries are extremely common in the general population and in orthopedics routine care. Its increasing incidence, which is motivated by an aging population, improved access to the health care system, increased prescription of continuous-use medication, erratic participation in sports and other factors, has had a direct impact on society. Consolidated treatment options for tendinopathies lack quality scientific support for many modalities. New therapies have emerged to enhance nonsurgical approach outcomes and to reduce the number of patients requiring surgery. Although these operative procedures provide good pain relief and functional outcomes, they are costly and may lead to complications.

Resumo As afecções que acometem o tendão calcâneo são extremamente comuns na população geral e no cotidiano da atenção ortopédica. Sua crescente incidência, motivada pelo envelhecimento da população, pela melhora no acesso à saúde, pelo aumento na utilização de drogas de uso contínuo, pela errática participação esportiva e outros fatores, tem causado impacto direto na sociedade. As tendinopatias, ainda que hoje respaldadas por tratamentos consolidados, carecem de suporte científico de qualidade para muitas das suas recomendações. Novas terapêuticas têm surgido com o objetivo de potencializar o resultado da abordagem não-operatória e diminuir a quantidade de pacientes que necessitam de uma cirurgia. Esses procedimentos operatórios apresentam uma boa resposta álgica e funcional dos pacientes, no entanto não são livres de complicações e dos altos custos que os cercam.

Achilles Tendon Lesions - Part 2: Ruptures / Lesões do Aquiles - Parte 2: Rupturas

Abstract The increasing incidence of calcaneal tendon ruptures has substantially impacted orthopedic care and costs related to its treatment and prevention. Primarily motivated by the increasing of life expectancy, the growing use of tenotoxic drugs and erratic access to physical activity, this injury accounts for considerable morbidity regardless of its outcome. In recent years, the evolution of surgical and rehabilitation techniques gave orthopedists better conditions to decide the most appropriate conduct in acute tendon rupture. Although still frequent due to their high neglect rate, Achilles chronic ruptures currently find simpler and more biological surgical options, being supported by a new specialty-focused paradigm.

Resumo A crescente incidência de rupturas do tendão calcâneo tem impactado substancialmente o cuidado ortopédico e os custos relacionados ao seu tratamento e prevenção. Motivada principalmente pelo aumento da expectativa de vida, o crescimento do uso de drogas tenotóxicas e o acesso errático à atividade física, essa lesão gera morbidade considerável aos pacientes qualquer seja o desfecho a ser considerado. A evolução das técnicas cirúrgicas e de reabilitação permitiu que ortopedistas, nos últimos anos, tivessem melhores condições para decidir a conduta mais apropriada nas roturas agudas do tendão calcâneo. Por mais que ainda frequentes pela sua alta taxa de negligência, as rupturas crônicas do Aquiles hoje encontram opções operatórias biológicas mais simples e são amparadas por um novo paradigma que se debruça sobre a especialidade.

Intervention Protocol of the Orthopedics and Traumatology Department of a High-Complexity University Hospital to Cope with the COVID-19 Pandemic / Protocolo de intervenção do Departamento de Ortopedia e Traumatologia de um hospital universitário de alta complexidade para enfrentamento da pandemia de COVID-19

Abstract Objective To describe the protocols implemented to adapt the orthopedic team to the COVID-19 pandemic; a secondary objective is to assess the behavior of hospital and departmental variables when implementing such measures. Methods The present is a retrospective study describing three protocols: 1) reduction in the risk of infection for patients and healthcare workers; 2) adaptation of work, academic and scientific activities; and 3) adaptation of the orthopedic treatment during the pandemic. We analyzed hospital and departmental variables, including the number of patients seen in the emergency room and outpatient clinic, the number of hospitalized patients, suspected and confirmed cases in patients and orthopedic team members, changes in teaching activities from on-site attendance to videoconferencing, and number of surgeries. Period A, from March 3 to 16, was compared with period B, from March 17 to 30, 2020, which corresponded to the implementation of the protocols. Results There was a decrease in the number of outpatients and inpatients. One confirmed and two suspected cases were notified. Among the departmental members, there were 12 suspected and 6 confirmed cases. The weekly frequency of classes was maintained, while the clinical-scientific meetings decreased from ten to three. In addition, the number of surgeries was reduced. Conclusions The present study demonstrated the feasibility and efficiency of the rapid implementation of intervention protocols in the midst of the COVID-19 pandemic. The protocols focused on reducing the risk of infection for patients and healthcare professionals, adapting work, academic and scientific activities, and modifying the orthopedic treatment. With the application of the protocols, the healthcare, academic and scientific activities remained functional, prioritizing measures to confront the COVID-19 pandemic.

Com sua aplicação, mantiveram-se as atividades assistencial, acadêmica e científica funcionantes, priorizando-se medidas de enfrentamento à COVID-19.

Epidemiology of injuries due to ankle sprain diagnosed in an orthopedic emergency room / Epidemiologia das lesões por entorse do tornozelo diagnosticadas em pronto atendimento de ortopedia

ABSTRACT 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 Objetivo Avaliar na ressonância magnética a prevalência das diferentes lesões ligamentares do tornozelo e do pé, bem como de fraturas não diagnosticáveis radiograficamente, em pacientes com queixa de entorse do tornozelo. Métodos Foram incluídos no estudo 180 pacientes consecutivos, com história de entorse do tornozelo, atendidos em um serviço de Atenção Primária no período de 12 meses. Os achados dos exames de ressonância magnética foram catalogados e descritos. Resultados Aproximadamente 92% dos pacientes apresentaram algum tipo de lesão na ressonância. Dentre as injúrias observadas, estavam 379 lesões ligamentares, 9 lesões osteocondrais, 19 lesões tendíneas e 51 fraturas. Apenas 14 ressonâncias magnéticas (7,8%) não mostraram qualquer tipo de lesão. Observamos relação positiva entre lesões do complexo lateral, sindesmose e medial. No entanto, houve correlação negativa entre lesões ligamentares do tornozelo e aquelas do mediopé. Conclusão Foi alta a ocorrência de lesões secundárias à entorse. Apontamos correlação entre as lesões ligamentares laterais com as sindesmodais e do deltoide. Não notamos relação entre as lesões do deltoide e da sindesmose, e nem entre as ligamentares laterais e a subtlalar. Também não foram observadas relações entre as lesões do tornozelo e as do mediopé.

Subtar arthroscopic debridment for the treatment of sinus tarsi syndrome: case series

SUMMARY OBJECTIVE: The objective of this study is to report the results of arthroscopic debridement of the subtalar joint in eight patients with Sinus Tarsi Syndrome (STS) refractory to conservative treatment. METHODS: This is a retrospective study of eight patients with STS who underwent subtalar arthroscopy for debridement of the sinus tarsi between January 2015 and January 2017 after six months of conservative treatment. All patients answered an epidemiological questionnaire and underwent functional evaluation with the Visual Analogue Pain Scale (VAS) and the American Orthopedic Foot and Ankle Society Score (AOFAS) in the preoperative and in the last evaluation (average of 12 months - 6-24 months). RESULTS: All patients showed severe synovitis in the region. Seven patients had remnants of the talocalcaneal ligaments and six of the cervical ligament. AOFAS increased by 30 points on average (51.75 in the preoperative period to 82.62 in the last follow-up) and the VAS decreased on average by 5 points (7.37 preoperatively to 2.12 in the last follow-up). These results were statistically significant with p = 0.043 and p = 0.032 respectively. Six patients described the result as excellent and two as good. No complications were reported. All patients returned to sports after six months of follow-up. CONCLUSION: The arthroscopic debridement of the subtalar joint is an effective and safe alternative in the treatment of STS refractory to conservative treatment. More studies, with a prospective methodology, are necessary to prove the results of this technique.

RESUMO OBJETIVO: O objetivo desse estudo é relatar os resultados do desbridamento artroscópico da subtalar em oito pacientes portadores da Síndrome do Seio do Tarso (SST) refratária ao tratamento conservador. MÉTODOS: Este é um estudo retrospectivo com oito pacientes com diagnóstico de STT que foram submetidos à artroscopia subtalar para desbridamento do seio do tarso entre janeiro de 2015 e janeiro de 2017, após seis meses de tratamento conservador. Todos os pacientes responderam questionário epidemiológico e foram submetidos à avaliação funcional com a Escala Visual Analógica de dor (EVA) e o American Orthopaedic Foot and Ankle Society Score (Aofas) no pré-operatório e na última avaliação, em uma média de 12 meses (6-24 meses). RESULTADOS: Todos os pacientes exibiram intensa sinovite na região. Sete pacientes tinham resquícios de ligamentos talocalcaneanos e seis do ligamento cervical. O Aofas aumentou 30 pontos em média (51,75 no pré-operatório para 82,62 no último seguimento) e a EVA diminuiu em média 5 pontos (7,37 no pré-operatório para 2,12 no último seguimento). Esses resultados foram estatisticamente significativos com p = 0,043 e p = 0,032, respectivamente. Seis pacientes descreveram o resultado como excelente e dois como bom. Nenhuma complicação foi relatada. Todos os pacientes retornaram ao esporte após seis meses de acompanhamento. CONCLUSÃO: O desbridamento artroscópico da subtalar é uma alternativa eficaz e segura no tratamento da SST refratária ao tratamento conservador. Mais estudos, com metodologia prospectiva, são necessários para comprovar os resultados da técnica.

Lesões do aparelho locomotor nos acidentes com motocicleta / Musculoskeletal injuries in motorcycle accidents

Estudo realizado no município de São Paulo entre janeiro de 2001 e julho de 2002 e tem como objetivo analisar o perfil do indivíduo envolvido em acidentes motociclísticos avaliando: o perfil do condutor, as circunstâncias dos acidentes, as lesões e o uso de equipamentos de segurança. Foram encontrados 387 pacientes sendo 354(91,0 por cento) do sexo masculino, entre 16 e 44 anos e considerados os indivíduos que necessitaram somente do tratamento traumato-ortopédico. O mecanismo de trauma mais comum envolveu a colisão entre a moto com outro veículo (67,0 por cento), numa velocidade entre 20-60km/h (73,0 por cento), em pessoas com menor experiência (67,0 por cento) na idade entre 21-24 anos (45,0 por cento), nos quais 532 (53,9 por cento) lesões ocorreram nos membros inferiores. Quanto ao tipo de lesão tivemos 393(39,8 por cento) ferimentos, 314(31,8 por cento) contusões e 212(21,5 por cento) fraturas [ossos do pé 34(16 por cento), fêmur 32(15,1 por cento), tornozelo 27(12,7 por cento), tíbia 25(11,8 por cento)]. A reincidência foi observada em 231(60,0 por cento) acidentes e somente 6,0 por cento dos pacientes não usavam equipamentos de proteção.O aumento da velocidade relacionou-se à um índice maior de fraturas quando foi aplicado o teste de Mann-Whitney (p=0,001). Pesquisas de engenharia mecânica e de engenharia de tráfego, associadas à rigorosa fiscalização e conscientização da população, devem ser consideradas o método mais efetivo , que é o da prevenção.

Study conducted in the city of São Paulo from January 2001 to July 2002 with the goal of analyzing the profiles of individuals involved in motorcycle accidents, evaluating the rider's profile, the circumstances of the accidents, injuries, and the use of protective gear. 387 patients needing only traumatic orthopedic treatment were found, between 16 and 44 years of age, of which 354 were males (91.0 percent). The most common mechanism of trauma involved a collision between the motorcycle and another vehicle (67.0 percent) at a speed between 12.5-37.5 mph (73.0 percent) involving less experienced riders (67.0 percent) between 21 and 24 years of age (45 percent), and in which 532 (53.9 percent) lower limb injuries occurred. Of the injuries, 393 (39.8 percent) were wounds, 314 (31.8 percent) were bruises and 212 (21.5 percent) were fractures [foot, 34 (16 percent); femur, 32 (15.1 percent); ankle, 27 (12.7 percent); tibia, 25 (11.8 percent)]. Recurring accidents were observed in 231 (60.0 percent) cases and only 6.0 percent of the riders were not using protective equipment. Increased speed showed a higher rate of fractures when the Mann-Whitney test was applied (p = 0.001). Research on mechanical and traffic engineering, in combination with supervision and awareness-raising of the population, should be considered the most effective methods of prevention.
