Abstract Objective To investigate the epidemiology of injury types among jiu-jitsu practitioners, as well as the incidence regarding different skill and experience levels, through the question: "What are the characteristics and prevalence of musculoskeletal injuries in Jiu-Jitsu practitioners?". Methods Since the beginning of the study, in August 2020, we conducted a search on the MEDLINE, LILACS, and SciELO electronic databases. We included cross-sectional studies published between 2018 and 2023 on the epidemiology of the types of injuries among jiu-jitsu practitioners that compared their incidence regarding different levels of ability and experience. Two independent researchers performed the data extraction and assessed the risk of bias. Results Seven studies were included. The common outcomes involved 2,847 jiu-jitsu practitioners. A high prevalence in the knee joint and chest and rib areas was reported. Considering the difference in experience level among the practitioners, we could observe that most of the individuals included were beginners. Among the age groups observed, male practitioners older than 30 years of age were the ones who presented the highest rate of musculoskeletal injury, especially during training sessions. Conclusion There is a high prevalence of musculoskeletal injuries among jiu-jitsu practitioners. The most affected anatomical segments are the knee joint, the chest, and the rib region, followed by the shoulder joint. The related factors change according to certain variables, being more common during training in male individuals over 30 years of age and beginners in the sport.

Orthopedic Injuries in Beach Tennis Players in Brazil / Lesões ortopédicas nos praticantes de beach tennis no Brasil

Abstract Objective To analyze the epidemiological data of orthopedic injuries in beach tennis players. Methods We conducted a cross-sectional study, through a questionnaire, with 185 beach tennis players during tournaments and training sessions in two cities. The questionnaire comprised anthropometric data, as well as data on length of time practicing the sport and reported orthopedic injuries. Results We excluded 25 of the 185 interviewees. Of the 160 players studied, 51.9% were male and 48.1%, female. The average age was of 40.4 years, the average height was of 1.73 m, the average weight was of 75.6 kg, and the average body mass index (BMI) was of 25.2 kg/m2. Orthopedic injuries were reported by 48.8% of the participants, 30.0% in the lower limbs, 11.3% in the spine, and 25.0% in the upper limbs, with an incidence of 0.82 per one thousand hours of practice. Correlating the incidence of injuries with age, weight, height, and BMI, we only found relevance between the higher average age in patients with lower- and upper-limb injuries. Players who had no previous experience with other racket sports had fewer injuries. Other parameters, such as gender, use of the two-handed backhand, dominant side, participation in competitions, and practice of other sports did not show statistically significant differences. Conclusion Orthopedic injuries were found in almost half of the beach tennis players, primarily in the lower limbs. Age, experience with other racket sports, category, hours of training per week, and length of time playing the sport influenced the incidence of orthopedic injuries.

Resumo Objetivo Analisar os dados epidemiolügicos das lesões ortopédicas nos praticantes de beach tennis. Métodos Foi realizado um estudo transversal, por meio de questionário, em 185 praticantes de beach tennis, durante torneios e treinos, em duas cidades. O questionário consistiu na coleta de dados antropométricos, além de dados relativos ao tempo de prática do esporte e às lesões ortopédicas referidas. Resultados Excluímos 25 dos 185 entrevistados. Dos 160 praticantes estudados, 51,9% eram do sexo masculino, e 48,1%, do feminino. A média de idade foi de 40,4 anos, a média da estatura foi de 1,73 m, a média do peso, de 75,6 kg, e a média do índice de massa corporal (IMC), de 25,2 kg/m2. A presença de lesões ortopédicas foi relatada por 48,8% dos praticantes, sendo 30,0% nos membros inferiores (MMII), 11,3% na coluna, e 25,0% nos membros superiores (MMSS), com incidência de 0,82 a cada mil horas de prática. Correlacionando a incidência de lesões com idade, peso, altura e IMC, encontramos relevância apenas entre a média de idade maior nos pacientes com lesão nos MMII e MMSS. Os jogadores que não tinham experiência prévia com outros esportes com raquete tiveram menos lesões. Demais parâmetros, como sexo, uso do backhand com duas mãos, lado dominante, participação em competições e prática de outros esportes não obtiveram diferenças estatisticamente significantes. Conclusão Lesões ortopédicas foram encontradas em quase a metade dos praticantes de beach tennis, preferencialmente nos MMII. Idade, experiência com outros esportes de raquete, categoria, horas de treino por semana e tempo de prática do esporte influenciaram na incidência de lesões ortopédicas.

Orthopedic sports injuries: advanced imaging modalities, return-to-play criteria, and injury prevention

Orthopaedic sports injuries encompass a wide range of musculoskeletal conditions resulting from the physical demands of athletic activities. These injuries can vary from acute, such as sprains and fractures, to chronic overuse syndromes like tendinopathies. Prevalent due to the global enthusiasm for sports, they affect bones, muscles, tendons, ligaments, and joints. The etiology of these injuries is multifactorial, stemming from biomechanical stressors, training methods, genetics, and environmental conditions. Advanced imaging modalities like magnetic resonance imaging and Computed tomography have revolutionized the assessment and diagnosis of these injuries, aiding in treatment decisions and return-to-play criteria. Injury prevention is paramount and involves understanding intrinsic (athlete-related) and extrinsic (environmental) risk factors. Strategies include pre-participation screening, strength and conditioning programs, biomechanical analysis, neuromuscular training, proper equipment use, rule changes, education, and creating a safety-conscious culture. Effective prevention reduces the burden of these injuries. Treatment strategies range from conservative approaches to surgery, depending on the type and severity of the injury. Emerging trends in sports medicine, including biologic therapies and telemedicine, offer promising avenues for improved diagnosis and recovery. The holistic approach to orthopaedic sports injuries encompasses prevention, diagnosis, and treatment, ensuring athletes' well-being and longevity in their chosen sports.

Comparison of the effects of mental fatigue induction tasks / 中国组织工程研究

BACKGROUND:Conducting mental fatigue research in sports depends on appropriate mental fatigue induction tasks.However,the different types and time settings for the tasks in this field have interfered with the selection and determination of the appropriate task for mental fatigue research. OBJECTIVE:To compare the effects of three mental fatigue tasks and their commonly used time settings for mental fatigue induction. METHODS:In this randomized crossover study,16 male amateur soccer players performed four tasks of 60-minute duration with an interval≥48 hours in a randomized counter-balanced order:STROOP task(psychological cognition group),social media use in smartphone(electron exposure group),whole-body coordination task(exercise group)and emotionally neutral video watching as controls(control group).Before each task,the visual analogue scale(VAS)-motivation,VAS-mental fatigue,VAS-physical fatigue,and average heart rate were measured.Also,the VAS-mental fatigue,VAS-mental exertion,VAS-physical fatigue,and average heart rate were recorded every 15 minutes during the task.Repeated measures analysis of variance was mainly used for statistical analysis. RESULTS AND CONCLUSION:The baseline level of VAS-mental fatigue in the four groups were similar(P=0.806).(2)The VAS-mental fatigue of the psychological cognition group at 30,45 and 60 minutes was significantly higher than that of the other three groups(all P＜0.05).The VAS-mental fatigue of psychological cognition,electron exposure,and exercise groups at 45 minutes were similar with that at 60 minutes(all P＞0.05),but significantly higher than that of pretest,15 minutes and 30 minutes(all P＜0.05).To conclude,the psychological cognition task is superior to the electron exposure and exercise tasks for mental fatigue induction and 45 minutes is the appropriate length of time to effectively induce mental fatigue.

Diferenças Étnicas na Sobrevida entre Medalhistas Olímpicos Brasileiros da Era Moderna de 1920 a 1992: Um Estudo de Coorte / Ethnic Differences in Survival among Brazilian Modern-era Olympic Medalists from 1920 to 1992: A Cohort Study

Resumo Fundamento: As disparidades nos resultados de saúde entre grupos raciais merecem investigação, mesmo em atletas de elite. Portanto, compreender o impacto da raça na sobrevida pós-medalha em atletas olímpicos brasileiros torna-se essencial. Objetivo: Comparar a sobrevida pós-medalha entre medalhistas olímpicos brasileiros brancos e não brancos de 1920 a 1992. Métodos: Utilizamos dados disponíveis publicamente para um estudo de coorte retrospectivo de todos os medalhistas olímpicos brasileiros de 1920 a 1992 (somente homens). Os atletas foram classificados nos grupos brancos e não brancos usando determinação estruturada de etnia. As análises de Kaplan-Meier calcularam o tempo médio de sobrevida restrito (TMSR) para cada grupo étnico. Uma análise de riscos proporcionais de Cox avaliou as diferenças de sobrevida baseadas na etnia, ajustando para a idade da conquista da medalha e ano de nascimento (p<0,05). Resultados: Entre 123 atletas (73,9% brancos), a idade média da conquista de medalhas foi de 25,03 ± 4,8 anos. Durante o estudo, 18,7% dos atletas brancos e 37,5% dos atletas não brancos morreram (p=0,031). Os atletas brancos tiveram média de idade ao óbito de 75,10 ± 18,01 anos, enquanto os atletas não brancos tiveram idade média de 67,13 ± 14,90 anos (p=0,109). O TMSR para atletas brancos foi de 51,59 (IC 95%, 49,79 - 53,39) anos, e para atletas não brancos foi de 45,026 (IC 95%, 41,31 - 48,74) anos, resultando em um ΔTMSR de 6,56 (IC 95%, 2,43 - 10,70; p=0,0018). A análise multivariada mostrou que atletas não brancos apresentavam maior risco de mortalidade do que atletas brancos (RC 5,58; IC 95%, 2,18 - 14,31). Conclusão: Após a primeira medalha, os atletas olímpicos brasileiros brancos normalmente desfrutam de uma expectativa de vida seis anos mais longa do que seus colegas não brancos, ilustrando uma acentuada diferença de mortalidade e disparidades de saúde entre indivíduos saudáveis no Brasil.

Abstract Background: Disparities in health outcomes among racial groups warrant investigation, even among elite athletes. Therefore, understanding the impact of race upon post-medal survival in Brazilian Olympians becomes essential. Objective: To compare post-medal survival between white and non-white Brazilian Olympic medalists from 1920 to 1992. Methods: This study used publicly available data for a retrospective cohort study on all Brazilian Olympic medalists from 1920 to 1992 (males only). Athletes were classified into white and non-white groups using structured ethnicity determination. Kaplan-Meier analyses computed the restricted mean survival time (RMST) for each ethnic group. A Cox proportional hazards analysis assessed ethnicity-based survival differences, adjusting for medal-winning age and birth year (p<0.05) Results: Among 123 athletes (73.9% white), the mean age of medal achievement was 25.03±4.8 years. During the study, 18.7% of white and 37.5% of non-white athletes died (p=0.031). White athletes had a mean age at death of 75.10±18.01 years, while non-white athletes had an age of 67.13±14.90 years (p=0.109). The RMST for white athletes was 51.59 (95% CI 49.79-53.39) years, while for non-white athletes, it was 45.026 (95% CI 41.31-48.74) years, resulting in a ΔRMST of 6.56 (95% CI 2.43-10.70; p=0.0018). Multivariate analysis showed that non-white athletes had a higher mortality risk than did white athletes (HR 5.58; 95% CI, 2.18-14.31). Conclusion: Following their first medal, white Brazilian Olympians typically enjoy a six-year longer lifespan than their non-white counterparts, illustrating a marked mortality gap and health disparities among healthy individuals in Brazil.

Anterior dislocation of the lunate due to a high-energy trauma / Luxación anterior del semilunar debido a un traumatismo de alta energía

Abstract: Semilunate and perilunate dislocation is an injury that mostly occurs when the subject is exposed to a high-energy trauma. Considered severe, it compromises the stability and function of the wrist. The case presented is that of a 50-year-old male patient who after having a motorcycle accident arrived at the ER with neurovascular affectation, swelling, deformity and a considerable decrease of the wrist joint movement. He was also referring severe pain. A Henry (Volar) intervention was done with the help of external fixation of the lunate, followed by K-wire fixation, once a prior closed reduction was unsuccessfully attempted. The scaphoid was connected to the semilunate, and then the latter with the capitate. Ligament reconstruction followed, and stability was clinically confirmed with an X-ray. Although improvement of symptomatology was observed during the follow-up analysis, motion of the wrist remained limited. Even with the best treatment, in terms of functionality, this type of injury presents a poor prognosis.

Resumen: La luxación semilunar y perilunar es una lesión que se produce principalmente cuando el sujeto está expuesto a un traumatismo de alta energía. Considerada grave, compromete la estabilidad y la función de la muñeca. El caso presentado es el de un paciente varón de 50 años que tras sufrir un accidente de motocicleta llegó a urgencias con afectación neurovascular, tumefacción, deformidad y una considerable disminución del movimiento articular de la muñeca. También refería fuertes dolores. Se realizó una intervención de Henry (Volar) con la ayuda de fijación externa del lunar, seguida de fijación con agujas de Kirschner, una vez que se había intentado sin éxito una reducción cerrada previa. El escafoides se conectó con el semilunar y luego éste con el capitado. A continuación se reconstruyó el ligamento y se confirmó clínicamente la estabilidad con una radiografía. Aunque se observó una mejora de la sintomatología durante el análisis de seguimiento, el movimiento de la muñeca seguía siendo limitado. Incluso con el mejor tratamiento, en términos de funcionalidad, este tipo de lesión presenta un mal pronóstico.

Finite element analysis of hip joint stress distribution based on CT imaging in marathon runners during the gait cycle / 中华放射学杂志

Objective:To explore the distribution of perihip stress in male marathon runners and normal volunteers during the gait cycle using finite element analysis.Methods:In November 2022, the hip joint CT image data of a male marathon runner and a male healthy volunteer was collected. The gait cycle was divided into 7 phases, including the foot to the ground, the early, middle, and late period of one-foot support, the toe push and extension period, and the beginning and end of the swing. A three-dimensional finite element model was constructed based on the gray value of CT and according to the individualized material attribute assigning scheme. The dynamic change of hip joint contact force during the gait cycle was applied to the load, and the biomechanical qualitative analysis of the model was carried out through the equivalent stress results. Based on qualitative analysis, the same 10 nodes on the front, middle, and back of the model acetabulum, the front, and back of the femoral head, and the neck of the femur were extracted as equivalent stress reference points, and the biomechanical quantitative analysis of the model was carried out.Results:During the gait cycle, according to the hip equivalent stress distribution diagram, the contact on the articular surface of the two subjects mainly occurred in the posterior upper part of the acetabulum and the posterior part of the femoral head and gradually moved outward and backward with the joint force during walking. From the point of view of the stress distribution nodes around the hip joint, the stress changes of the nodes in each part of the two subjects showed bimodal characteristics with the load inside the hip joint at each phase. The internal stress value of the hip joint showed a gradual upward trend from the foot to the ground, reached the maximum stress in the middle period of one-foot support, then decreased, and slightly increased in the toe push and extension period. Then, the stress values at the beginning and end of the swing gradually decreased until entering the next gait cycle. The stress values in the posterior acetabulum and posterior femoral head of the marathon runner were smaller than those of the healthy volunteer.Conclusion:The stress around the hip joint was different between marathon runner and healthy volunteer, but the stress distribution and transmission path were the same.

Development and future of minimally invasive hip arthroscopy surgery technology in China / 中华骨科杂志

Hip surgery has been a slow-growing specialty in orthopedics and sports medicine. The development of imaging and minimally invasive arthroscopic surgery techniques has brought opportunities for this branch. Compared with other minimally invasive joint techniques, hip arthroscopy develops more slowly due to high equipment requirements, difficult operation and long learning curve. However, with continuous breakthroughs in disease diagnosis and surgical techniques, hip arthroscopy technology has stayed in a fast track for the past 20 years, and has become the most rapidly developed field in sports medicine. Especially in the past decade, China's hip arthroscopy society has developed rapidly in both surgery volumes and types. With an increasing population of hip doctors, the technical level and related research gap between China and the outside world narrowed. In some research fields, China even surpassed them. In general, both domestic and overseas studies show that the effect of hip arthroscopy is positive with significant improvement of symptoms in most patients. However, some patients complained poor recovery and residual hip pain, which indicates that hip diseases are still not totally understood, and the development of hip arthroscopy technology is still in an early stage. Therefore, accurate diagnosis and indication selection, detailed assessment of patients' exercise needs and psychological status, perfect preoperative planning, skilled surgical operation, and strict functional rehabilitation are the keys to success, which should be kept in mind by every hip arthroscopy doctor. They are also the main research direction for hip arthroscopy doctors. Continuous efforts on clinical and basic research should be made for the development of hip arthroscopy to establish a more optimized and comprehensive diagnosis and treatment system.

Radiographic evaluation of femoral acetabular impingement / 中华骨科杂志

Femoral acetabular impingement (FAI) is a condition characterized by abnormal anatomical structures of the femoral head and/or acetabulum, leading to impingement between the proximal femur and the rim of the acetabulum during hip movement. This impingement causes damage to the acetabular cartilage, labrum, chronic hip pain, and limited range of motion. The diagnosis of this condition requires evaluation based on symptoms, physical signs, and imaging examinations. Among these, imaging plays a crucial role in assessing the pathology of FAI. In recent years, imaging techniques have contributed to a deeper understanding of the mechanisms underlying FAI and the development of hip-preserving surgeries. The purpose of this paper is to provide a reference for the imaging-related diagnosis and measurement of FAI. X-ray films include pelvic anteroposterior view, false-profile view and 45°Dunn view. Doctors can understand the anatomical morphology of the femur and acetabulum by measuring relevant indicators in the X-ray films. For example, the α Angle of the femur >50°-60 ° in the pelvic anteroposterior view can indicate CAM-type FAI. However, the crisscross sign, posterior wall sign and LCE Angle >40° suggest Pincer type FAI. The ACE Angle, which reflects the anterior coverage of the acetabulum, was mainly measured on the false-profile view. The ACE Angle <20° is considered as insufficient anterior acetabular coverage, and acetabular dysplasia may be present.If it >40° is the anterior acetabular overcoverage, suggesting pincer-type FAI. The 45°Dunn view is mainly used to show the femoral head and neck deformity at 3 o'clock, where the femoroacetabular impingement is obvious. This position has a good indication effect for CAM-type FAI. CT can show the shape of the hip joint more intuitively by three-dimensional reconstruction of the patient's hip joint, which is convenient for surgical planning and postoperative evaluation. In addition, CT can also be used for the differential diagnosis of external hip impingement, such as ischiofemoral impingement, anterior inferior iliac spine impingement and greatertrochanteric impingement. MR Has excellent soft tissue imaging ability and can show other lesions that are difficult to be found by X-ray and CT, such as acetabular labrum and cartilage injury. It is essential for preoperative evaluation. Appropriate imaging examination plays a key role in the diagnosis and treatment of FAI.
