Rectus Femoris Muscle Injury Radiology Reference Article

Rectus Femoris Muscle Injury Radiology Reference Article The rectus femoris muscle crosses two joints, plays an active part in knee extension and hip flexion and features a high proportion of fast twitch (type ii) muscle fibres and is characterised by a complex musculotendinous architecture, which is considered a predisposing factor for strain injury 1. muscle injury patterns include strains. Typically, muscle injuries present with pain and loss of function. clinically, they can be graded as 1: grade 1: no appreciable muscle tearing; <5% loss of function strength. grade 2: damage to the musculotendinous junction (mtj); reduced strength; some residual function. grade 3: complete tear of the musculotendinous junction; loss of function.

Rectus Femoris Muscle Injury Radiology Reference Article Rectus femoris muscle injury usually consists of a myotendinous strain centered on the indirect or direct head or, less commonly, myofascial junction injury, at the periphery of the muscle. the majority of rectus femoris injuries occur about the deep intramuscular musculotendinous junction 9. other injuries to the quadriceps mechanism include. Mri provides detailed images of muscle injury and can be quite helpful in characterizing quadriceps injuries [5, 12, 13]. it can sometimes be difficult to distinguish between muscular contusion and strain on mri, which simply re enforces the importance of clinical history and examination in injury assessment [ 12 ]. Clinically relevant anatomy. the unique anatomy of the rectus femoris helps to facilitate its action as an antagonistic muscle to the hamstring muscles at the hip and the knee joints. 1,6 the rectus femoris is fusiform in shape and arises from two proximal tendon heads, the superficial direct head that originates from the anterior inferior iliac spine, and the deep reflective head that. Seven of the 15 rectus femoris injuries involved the central (intramuscular) tendon. they described a typical mri appearance (figure 2d) showing a feather like pattern of injury in the coronal t2 view. the clinical importance of this intramuscular tendon involvement is shown by the prolonged rehabilitation time in this group (27 days) compared.
