“…Our finding that most hamstring injuries affected the biceps femoris muscle was consistent with previous studies in Australian football (Connell, et al, 2004;Koulouris, Connell, Brukner, & Schneider-Kolsky, 2007). Furthermore, in accordance with the findings of Slavotinek et al (Slavotinek, Verrall, & Fon, 2002), we found no relationship between the specific muscle involved and the lay-off time.…”

“…It is possible that these cases involve subtle muscle injury that is below the sensitivity of MRI detection (Verrall, Kalairajah, Slavotinek, & Spriggins, 2006). Another possibility is that players could have an alternative diagnosis, such as back-related problems, neural tension, or muscle spasm (Connell, et al, 2004;Koulouris, et al, 2007;Müller-Wohlfahrt, Ueblacker, & Hänsel, 2013;Müller-Wohlfahrt, Ueblacker, & Hänsel, 2010).…”

195 wordsRunning title: Return to play after muscle injuries. 2 AbstractThis prospective cohort study described return-to-play (RTP) data for different types of muscle injuries in male elite level football players in Europe. Eighty-nine European professional teams were followed between 2001 and 2013. Team medical staff recorded individual player exposure and time-loss injuries. A total of 17,371 injuries occurred, including 5603 (32%) muscle injuries. From 2007, we received results from 386 magnetic resonance imaging (MRI) examinations, and radiological grading was performed. A negative MRI was associated with shorter recovery time (6 ± 7 days). Lay-off days were correlated with MRI grading of thigh muscle injuries (P < 0.001). Among hamstring injuries, 83% occurred to the biceps femoris, 12% affected the semimembranosus, and 5% the semitendinosus. Recurrence rate was higher among biceps femoris injuries (18%) compared to semitendinosus and semimembranosus injuries (2% together). Groin muscle injuries caused shorter median absence (9 days) than hamstring (13 days; P < 0.001), quadriceps (12 days; P < 0.001), and calf muscle (13 days; P < 0.001) injuries. Overall, we found that MRI was valuable for prognosticating RTP, with radiological grading associated with lay-off times after injury. Re-injuries were common in biceps femoris injuries but rare in semitendinosus and semimembranosus injuries.Running title: Return to play after muscle injuries.3

“…This, together with the capability to evaluate multiple anatomic planes, make it the most suitable technique to evaluate muscle injures [23][24][25][26]. Most muscle injuries might not require imaging, but as this noninvasive technology continues to improve and becomes even more commonplace, it can play a role in rehabilitation planning and prognosis [3].…”

Background Muscle strains are one of the most common complaints treated by physicians. High-force lengthening contractions can produce very high forces resulting in pain and tissue damage; such strains are the most common cause of muscle injuries. The hamstring muscles are particularly susceptible as they cross two joints and regularly perform lengthening contractions during running. We describe a patient with return to full function after a large hamstring tear. Case Description We report the case of a 26-year-old man who presented 1 year after a noncontact, left-sided proximal hamstring tear incurred while sprinting. He received no medical treatment or formal rehabilitation. He was able to return to all sports and activities 1 to 2 months after injury, but noted a persistent deformity of the proximal thigh, which led him to seek evaluation. Physical examination, MRI functional tests, and specific muscle tests 1 year after his injury documented a major hamstring tear at the musculotendinous junction with muscle retraction, but no avulsion of the proximal tendon attachment. Literature Review Surgery often is recommended for major proximal hamstring tendon tears, especially when more than one tendon of origin is ruptured from the ischial tuberosity. Myotendinous tears are treated nonoperatively, but may be associated with decreased strength, prolonged recovery, and recurrence. Purpose and Clinical Relevance We describe the case of a young man who sustained a hamstring tear, with retraction, at the proximal myotendinous junction, where the biceps femoris and semitendinosus arise from the conjoint tendon. He achieved full functional recovery without medical attention, but had a persistent cosmetic deformity and slight hamstring tightness. This case suggests a benign natural history for this injury and the appropriateness of noninvasive treatment.

“…Magnetic resonance imaging (MRI) is more accurate in the assessment of acute hamstring injuries than most other imaging modalities (Connell et al 2004;Verrall et al 2006;Koulouris et al 2007;Askling et al 2013a). It has the ability to diagnose hamstring pathology, such as subtle tendinosis (tendinopathy), tears and low-grade bursitis for the purposes of guiding rehabilitation and possible radiologically guided intervention (Verrall et al 2006;Askling et al 2013a).…”
