Seatbelt Anterior Cruciate Ligament Reconstruction: A Variant of Internal Brace in Anterior Cruciate Ligament Reconstruction With an Adjustable Loop.

In recent years, there has been a growing interest in primary anterior cruciate ligament repair with the help of mechanical reinforcement techniques that employ synthetic grafting. The concept of ligament augmentation with reinforcement suture or internal bracing consists of stabilizing the repaired ligament and augmenting it with an ultra-high molecular weight polyethylene suture or tape, which guarantees greater resistance, safety during healing, and a more accelerated rehabilitation. In this work, we propose a variant of anterior cruciate ligament augmentation with suture, replacing the suture tape with an adjustable-loop reinforcement system, which is connected to the adjustable suspension devices for the graft in the femur and the tibia, surrounding the graft as a seatbelt.

The Epidemiology of Injuries in Spanish Rugby Union División de Honor.

BACKGROUND: We describe and analyze injury incidence, severity, cause of injury, anatomical location, damaged tissue, injury recurrence, and the time and place at which injuries occur over the course of a season. METHODS: An observational, descriptive, prospective, nomothetic, and multidimensional study was conducted during the 2018-2019 season with 258 players of the top semiprofessional rugby league in Spain (División de Honor de Rugby). Data were reported by the clubs' medical services. Reported time-loss injuries were collected. RESULTS: Overall exposure was 4100 h (137 matches), over 35 weeks of competition. A total of 288 injuries were reported, with three of these leading to withdrawal from the sport. A total average of 35.63 days was lost to injury. Overall time-loss injury incidence was 3.41 injuries/1000 h of exposure. Backs suffered 119 injuries corresponding to 3.80 injuries/1000 h of exposure, whilst forwards suffered 169 injuries with 4.27 injuries/1000 h of exposure. Severe injuries were the most frequent injury type. CONCLUSIONS: Outcomes confirm that more injuries take place during competition, with these also being more severe in nature. Contact injuries were most frequently suffered, above all, due to tackling or being tackled.

Perfil antropométrico comparativo entre jugadores juveniles de rugby de élite / Comparative anthropometric profile between of elite rugby union youth players

Introducción: La evaluación antropométrica de los deportistas es necesaria para optimizar la identificación y el desarrollo delos jugadores. Nuestro objetivo es describir las características antropométricas por posición en los jugadores de las seleccionesde rugby XV Sub18 y Sub20 durante dos temporadas.Material y método: A 152 jugadores de las selecciones de rugby XV Sub18 y Sub20 de España se les midió la estatura, masacorporal, pliegues cutáneos, porcentaje de tejido graso, masa muscular esquelética (MME), masa mineral ósea (MMO) y soma-totipo durante las temporadas 2015-2016 y 2016-2017. Se calculó el promedio y la desviación estándar para cada selección,grupo y posición. Se realizó el análisis de U de Mann-Whitney para comparar entre selecciones y por grupos. Para compararentre posiciones se utilizó la prueba de Kruskal-Wallis. Resultados: Los jugadores agrupados como delanteros presentan mayor masa corporal, estatura, porcentaje de tejido graso,MME y MMO que los tres cuartos (p <0,05). Los jugadores que ocupan la posición de piliers presentan mayor porcentaje detejido graso (p <0,05) y los que ocupan la posición de segunda línea son los de mayor estatura (p <0,05). Conclusiones: Los jugadores de élite en España Sub20 presentan mayor masa corporal, porcentaje de tejido graso y MMEque los jugadores élite de España Sub18. Los jugadores agrupados como delanteros de nivel élite en España Sub18 y Sub20presentan mayor masa corporal, estatura, porcentaje de tejido graso, MME y MMO que los jugadores agrupados como trescuartos. La posición con mayor masa corporal y porcentaje de tejido graso es la de piliers en los jugadores de élite de España en las categorías Sub18 y Sub20. Los jugadores de nivel élite que ocupan la posición de segundas líneas son los de mayorestatura en España en las categorías Sub18 y Sub20.(AU)

Background: Anthropometric evaluation of athletes is necessary to optimize talent identification and player development.The aim was to describe the anthropometric characteristics of national under-18 and under-20 rugby team by field positionsin two season. Material and method: 152 players of under-18 and under-20 rugby teams were to measured mass, stature, skinfolds, percentage body fat, skeletal muscle mass, bone mineral and somatype between 2015-2016 and 2016-2017 season. Mean andstandard deviation were calculated for each national team, groups and positional. The Mann-Whitney U test were performedto investigate differences between national team and by groups. The Kruskal-Wallis test was performed to investigate differences between positional. Results: The foward units were heavier, taller and had a larger percentage body fat and skeletal muscle mass than back units(p <0.05). The props had a larger percentage body fat (p <0.05) and the seconds row were taller (p <0.05).Conclusions: The elite players of under-20 in Spain are heavier and have a larger percentage body fat and skeletal musclemass than elite players of under-18. The foward units are heavier, taller and have a larger percentage body fat, skeletal musclemass and bone mineral tan back units. The props are heavier positional and have larger percentage body fat. The secondsrow are taller positional.(AU)

Epidemiology of Injuries Sustained by Elite Under-18 Rugby Players.

CONTEXT: The physical nature of rugby is responsible for the high incidence of injuries, but no researchers have examined the epidemiology of injuries sustained by elite under-18 rugby players. OBJECTIVE: To investigate the incidence of injuries sustained by players on the Spanish national under-18 rugby team during their participation in 4 European championships (2014-2017) and the types of play in which they occurred. DESIGN: Cohort study. SETTING: European rugby championships. PATIENTS OR OTHER PARTICIPANTS: Ninety-eight under-18 rugby players. MAIN OUTCOME MEASURE(S): All injuries sustained during the championship periods were recorded per the World Rugby protocol. RESULTS: A total of 40 injuries were logged over the 4 championships. The incidence of injury was higher during matches than during training (P < .05), with 138.0 (95% confidence interval [CI] = 136.5, 139.6) injuries per 1000 hours of play compared with 1.2 (95% CI = 1.2, 1.3) per 1000 hours of training. With only 2 days of rest between games, the injury rate was higher than with 3 days of rest (P < .05). More injuries were sustained during the third quarter of the game: 13 (44.8%) versus 6 (20.6%) in the last quarter, 5 (17.3%) in the second quarter, and 5 (17.3%) in the first quarter. CONCLUSIONS: The most common injuries during matches were sprains and concussions, and these injuries were more likely to occur during matches than during training. Most injuries were caused by tackles and occurred during the third quarter of the game. These findings indicate that teams should focus on teaching players skills to reduce injuries caused by tackles and warming up properly before returning to the field after halftime. The injury rate was higher with only 2 versus 3 days' rest between games. These results suggest that young players' matches should be at least 72 hours apart.
