Common hamstring origin tendinopathy with focal partial-thickness semimembranosus tear extending into the proximal free tendon portion.

Nov 14, 2022 · The MRI protocol is based on a coronal fatsat, Axial PD fatsat and axial T2 sequences. Coronal T2 fat saturation sequences (fatsat, STIR or dixon) allows for a quick overview of the injury and facilitates easy measurement of relevant distances (e.g. length of edema or tendon retraction).

MRI readily identifies the location and severity of the injury. In conjunction with the physical findings, this information helps guide a more comprehensive and effective rehabilitation program. The hamstrings are comprised of the semimembranosus, semitendinosus, and …

Dec 9, 2022 · grade 3: complete tear of the myotendinous junction; loss function +/- a palpable gap. There are numerous imaging classification systems including: British Athletics muscle injury classification (MRI-based) Radiographic features. There are no unique features of hamstring-specific injuries.

Nov 23, 2012 · MRI showing injury to the semimembranosus proximal myotendinous junction or the proximal free tendon (Figs. 8A and 8B) indicates a stretching injury and predicts a prolonged recovery time, typically 6–24 months [34, 35]. An injury localized to the long-head biceps femoris alone or combined with other muscles is characteristic of a typical ...

The objectives of this study were to characterize SM injuries in a group of athletes and determine if the anatomical location of injury as determined by MRI is associated with injury severity and time needed to return to play.

Nov 11, 2024 · Diagnosis can be made clinically with ecchymosis in the posterior thigh, tenderness over the hamstring muscles and avoidance of knee extension. Diagnosis can be confirmed with MRI.

Oct 28, 2019 · MRI is the best modality to detect the lesion and additional associated soft tissue injuries. The small bony fragment may be displaced or in situ. Associated anterior cruciate ligament rupture, posterior horn of medial meniscal tear and meniscocapsular separation are usually present.

Apr 23, 2014 · The objective of our study was to determine the prevalence of thickening and signal alteration of the distal semimembranosus (SM) tendon on knee MRI and analyze the patient factors associated with abnormal MR findings of the distal SM tendon.

Sep 16, 2024 · Magnetic Resonance Imaging (MRI) is the gold standard for diagnosing proximal hamstring tears. It helps determine the degree of tearing (partial vs. complete), the amount of tendon retraction (in full tears), and the extent of surrounding tissue and nerve damage.
