Avaliação por ressonância magnética das injúrias musculares traumáticas

Abstract

Neste trabalho foram avaliados 43 exames de ressonância magnética de perna ou coxa, com alterações traumáticas relacionadas à prática de esportes. Os estiramentos foram as lesões mais encontradas e apresentaram imagem iso ou hipointensa em T1 e hiperintensa em T2, sendo classificados, de acordo com a porcentagem de fibras lesadas, em graus 1, 2 e 3. Em segundo foram observadas as contusões, cujas características foram sinal hipo ou isointenso em T1 e hiperintenso em T2, e, por fim, as fibroses, que se caracterizaram por sinal hipointenso em T1 e em T2.

Avaliação isocinética dos músculos extensores e flexores de joelho em jogadores de futebol profissional

“…Thus, the auhtors found for the flexors power of 130.5% and for extensors, 235.2%. Maximal power despite representing functional values of muscular condition, does not present reference values (5,6,12,15,16) . This variable is hence specific for each population, and especially for each sports modality.…”

“…Power considers torque, distance to be completed (ROM) and time. Thus, Power represents the ratio between total work and the needed time to perform it (5,6,12,15,16) .…”

“…The muscular lesions are responsible for a third of the soccer maladies (1,5) , and can be classified as direct or indirect depending on the trauma mechanism. The direct lesions are lacerations and sprains, while the indirect ones are the muscle strains (6) .…”

Partial rupture of the thigh adductor muscle in a dog: case report

“…Finally, it is important to emphasize that the diagnosis and treatment should be instituted as soon as possible once muscular rupture may progress to fibrosis, muscle retraction, liposubstituition or ossificating myositis (Dias et al, 2001). The ultrasound evaluations were also useful to the follow-up of present case.…”

“…According to Fernandes et al (2011), more than 90% of these lesions are contusions or stretches, but lacerations are seldom diagnosed. According to Dias et al (2001), these lesions may be acute (due to overload) or chronic (excessive use). In dogs, muscular ruptures have already been described in different muscles (Cabon & Bolliger, 2014), however no reports have been found regarding the thigh adductor muscle.…”
