Comprehensive Classification

Muscle injuries are recognized to be among the most frequent injuries occurring in the sporting and athletic population, and they account for more than 30% of all injuries in professional soccer players. Despite their considerable frequency and impact, there is still a lack of uniformity in the categorization, description and grading of muscle injuries.Dozens of systems based on clinical signs, ultrasound imaging (US) appearance or magnetic resonance imaging (MRI) findings have been proposed over the years. Most of them are three-grade systems that take into account pain, ROM limitation, swelling and hematoma, hypoechoic or hyperintense areas on US or MRI, and muscle gap or tendon involvement; however, they still lack evidence-based prognostic value. Recently, new comprehensive classification systems have been proposed, with the aim of developing uniform muscle injury terminology and giving each severity grade prognostic value.The systems that combine detailed MRI and US features with the clinical presentation, such as the Munich Muscle Injury Classification, the ISMuLT classification, and the British Athletic Classification, if used extensively, could improve the diagnosis, prognosis and management of muscle injuries.

ObjectiveTo evaluate thermography application as a complementary method in preventing muscle injury in professional soccer players. MethodsA longitudinal prospective study with 28 professional soccer players that composed a first division of Brazilian’s soccer team between 2015 and 2016. In both seasons (2015 and 2016), muscle injuries were documented and classified in grade of severity, by ultrasound. During the following season (2016), infrared medical thermography was applied twice a week (48 hours after game) and if a difference of temperature was detected higher than 0.4°C, a prevention protocol was initiated. Muscle injuries in 2016 were documented.ResultsIn 2015, the total number of muscle injuries was 11. In 2016, the total number of muscle injuries was 4 (p=0.04). It represents an incidence/player of 78% in 2015 and 28% in 2016, corresponding to a decrease of 64% in 2016. Seven players played in the first team in both seasons. Among these seven players, muscle injuries were reduced from 8 (in 2015) to 3 (in 2016)—a decrease of 63% in the season we used thermographic monitoring (p=0.06).ConclusionThe pilot data provide a promising catalyst for a rigorous RCT that could examine whether thermography can contribute to a muscle injury prevention programme.

Background Muscular tightness is frequently postulated as an intrinsic risk factor for the development of a muscle injury. However, very little prospective data exist to prove this. Hypothesis Increased muscle tightness identifies a soccer player at risk for a subsequent musculoskeletal lesion. Study Design Prospective cohort study. Methods We examined 146 male professional soccer players before the 1999–2000 Belgian soccer competition. None of the players had a history of muscle injury in the lower extremities in the previous 2 years. The flexibility of the hamstring, quadriceps, adductor, and calf muscles of these players was measured goniometrically before the start of the season. All of the examined players were monitored throughout the season to register subsequent injuries. Results Players with a hamstring (N = 31) or quadriceps (N = 13) muscle injury were found to have significantly lower flexibility in these muscles before their injury compared with the uninjured group. No significant differences in muscle flexibility were found between players who sustained an adductor muscle injury (N = 13) or a calf muscle injury (N = 10) and the uninjured group. Conclusions These results indicate that soccer players with an increased tightness of the hamstring or quadriceps muscles have a statistically higher risk for a subsequent musculoskeletal lesion. Clinical Significance Preseason hamstring and quadriceps muscle flexibility testing can identify male soccer players at risk of developing hamstring and quadriceps muscle injuries.

Substantial Problem

Background: Muscle injuries affect up to 72% of professional soccer players within one season and there are well reviewed, but muscle injuries in youth soccer players are not widely documented. The aim of this study was to investigate incidence, localization, pathomechanism and point of time of indirect muscle injuries in youth soccer players. Methods: Prospective cohort study. 5 teams (U15, U16, U17, U18 and U21) with 110 young male football players (age 16,8 (14,3–21) years, height 174,5 (146,1–190,0) cm, weight 65,7 (35,5–84,6) kg) were monitored for 12 months. Every muscle injury was documented and monitored on a standardized evaluation score. Results: In total, 53 muscle injuries were registered. On average, a player sustained 0,4 muscle injuries per season. There was only one re-injury (2%). The injury rate was 1,5 injuries per 1000h match- or /training hours, the match injury rate (6,9) being 7,7 times higher than the training injury rate (0,9). Sixty-nine percent were functional muscle injuries. Thirty-seven percent of all muscle injuries affected the hamstrings group and twenty-eight percent the adductors. The most common pathomechanism was overload (28%). Most of the injuries were recorded during the last 15 minutes of a game or a training (39,6%). Conclusion: Muscle injuries are a substantial problem for players and clubs, also in young male football players. This study confirmed previous results showing that the injury rate during games is higher than during trainings and that hamstrings injuries are the most common muscle injuries in soccer. However, a prolonged study period is recommended to gain better statistical values.

There are recent data suggesting an association between the R577X polymorphism (rs1815739) in the gene encoding α-actinin-3 (ACTN3) and the risk of musculoskeletal injuries. The purpose of this study was to analyze the association of rs1815739 with risk of, and recovery time from non-contact soft-tissue muscle injuries in professional soccer players. Forty-six (22 male and 24 female) players from a top-level professional soccer team were assessed during five consecutive seasons: the genotype distribution was: RR, 41.3%; RX, 47.8%; and XX, 10.9%. There was a trend towards a higher risk of muscle injury associated with the XX genotype (p = 0.092, with no injury-free XX player during the 5-year study period) and a significant genotype effect for the time needed to return to play (p = 0.044, with the highest value shown for the XX genotype, i.e., 36 ± 26 days, vs. 20 ± 10 and 17 ± 12 days for RR and RX, respectively). In conclusion, the XX genotype might be associated not only with a higher risk of non-contact muscle injuries, but also of recovery time from these conditions. However, more research in larger cohorts is needed to confirm this preliminary hypothesis.

An 11-year-old male Rough collie was submitted with paraparesis, but did not respond to medical treatment. Clinical signs worsened and the dog displayed paralysis, inability to stand and loss of voluntary bladder control, whereupon magnetic resonance imaging (MRI) was performed. No significant abnormalities were identified from MRI, blood tests, cerebrospinal fluid tests or radiography. After MRI, the dog developed dyspnoea and died. Autopsy and subsequent histopathological examination led to a diagnosis of degenerative myelopathy.

ABSTRACT Objective: To identify the incidence of injuries, their main characteristics, and the way they were managed throughout 2016 in two major series of a professional soccer championship in São Paulo, Brazil. Methods: This prospective study used an electronic questionnaire previously developed by the Medical Committee of the Paulista Soccer Federation which was sent to the team doctors after each match. Results: Two hundred and fifty-nine injuries occurred during 361 matches, and the incidence of injury per 1000 hours of game play was 21.32. Strikers were the most affected by injury; the most frequent diagnosis was muscle injury and the legs were predominantly affected. Most of the injuries occurred in the last 15 minutes of the first half and only 7.7% required surgical treatment. Conclusions: Muscle injuries were the most frequent, with most occurring in forwards and in the legs. Approximately half of the injuries occurred after contact and the vast majority was treated without surgery. MRI was the most requested exam and most injuries were classified as moderate (8 to 28 lost play days).

  Se ha comprobado y establecido que alrededor del 66% de los componentes del rendimiento y estado del atleta se explican por los factores hereditarios. Dos de los polimorfismos genéticos mas estudiados con relación al rendimiento deportivo en la ultima década, son el ACTN3 R577X y el ACE I/D. El objetivo de este estudio fue resumir las posibles asociaciones de ambos polimorfismos y el rendimiento en jugadores de fútbol, determinando la combinación alélica y genotípica que más destaca en esta población y, además, observar las relaciones de estos a nivel físico y fisiológico. Para la realización de este estudio se llevaron a cabo dos fases, una primera de revisión bibliográfica y una segunda fase de clasificación y análisis de la información. Los estudios evidencian una mayor influencia de los alelos ACE-D y ACTN-R, y de los genotipos ACE-ID y ACTN-RR. Se observó que los sujetos con estas combinaciones tenían mejores rendimientos es pruebas de velocidad y fuerza. Por otro lado, el polimorfismo ACTN3 está directamente relacionado con las lesiones musculares. En conclusión, se pudo observar una relación entre los polimorfismos genéticos y el rendimiento en jugadores de fútbol. Los componentes genéticos se pueden integrar como un nuevo componente dentro de la caracterización del deporte y como una herramienta dentro de un modelo de identificacción y detección de talentos en el fútbol juvenil. Además, los biomarcadores genéticos podrían ser responsables en un futuro, del estudio del riesgo de lesiones para que se optimice mucho más el rendimiento en el fútbol profesional. Abstract. It has been verified and established that around 66% of the components of the athlete's performance and state are explained by hereditary factors. Two of the most studied genetic polymorphisms in relation to sports performance in the last decade are ACTN3 R577X and ACE I/D. The aim of this study was to summarize the possible associations of both polymorphisms and the performance in soccer players, determining the allelic and genotypic combination that stands out the most in this population and, also, to observe their relationships at the physical and physiological level. In order to complete this study, two phases were carried out, the first one of literature review and, the second one which covered the information classification and analysis. The studies show a greater influence of the ACE-D and ACTN-R alleles, and higher presence of the ACE-ID and ACTN-RR genotypes. Subjects with these combinations were found to perform better on speed and strength tests. On the other hand, the ACTN3 polymorphism is directly related to muscle injuries. In conclusion, a relationship between genetic polymorphisms and performance in soccer players could be observed. Genetic components can be integrated as a new component within the characterization of sport and as a tool within a model of identification and detection of talents in youth soccer. In addition, genetic biomarkers could be responsible, in the future, for the study of the risk of injury so that performance in professional soccer is much more optimized.

SummaryA two-year-old female Lucerne Hound was presented with a one-week history of signs of progressive neck pain, inappetence, apathy, and an elevated rectal temperature. Findings of magnetic resonance imaging (MRI) were consistent with a foreign body abscess in the epidural space at the level of the first and second cervical vertebrae. A leftsided dorso-lateral atlantoaxial approach was performed, revealing an epidural abscess containing a grass awn. The clinical signs resolved within three days of surgery and the dog made a full recovery. This case report shows that grass awns can migrate to the atlantoaxial region in dogs and MRI findings lead to a suspicion of caudo-cranial migration within the spinal canal.

Rectus femoris muscle strains are one of the most common injuries occurring in sports such as soccer. The purpose of this study was to describe the safety and feasibility of a combination of percutaneous needle electrolysis (PNE) and a specific rehab and reconditioning program (RRP) following an injury to the rectus femoris in professional soccer players. Thirteen professional soccer players received PNE treatment 48 h after a grade II rectus femoris muscle injury, followed by a the RRP 24 h later. Assessment of recovery from injury was done by registering the days taken to return to train (RTT), return to play (RTP), and structural and functional progress of the injured muscle was registered through ultrasound imaging and match-GPS parameters. Also, adverse events and reinjuries were recorded in the follow up period of twenty weeks. The RTT registered was 15.62 ± 1.80 days and RTP was 20.15 ± 2.79 days. After fourteen days, the ultrasound image showed optimal repair. Match-GPS parameters were similar before and after injury. There were no relapses nor were any serious adverse effects reported during the 20-week follow-up after the RTP. A combination of PNE and a specific RRP facilitated a faster RTP in previously injured professional soccer players enabling them to sustain performance and avoid reinjuries.
