Musculotendinous ruptures of the distal biceps brachii are extremely rare injuries whose clinical presentation is similar to distal biceps avulsion. We describe two cases of patients who suffered a distal biceps brachii musculotendinous partial rupture. The first patient was playing soccer as goalkeeper and experienced sudden pain while throwing the ball overhead with his left arm. The second p...

There is an interest in identifying the intrinsic risk factors, including altered musculotendinous flexibility, that may be associated with musculotendinous injuries. We have recently shown that a sequence variant, namely the BstUI restriction fragment length polymorphism (RFLP), within the COL5A1 gene is associated with chronic Achilles tendinopathy. Mutations within COL5A1 have been implicate...

A rare case is presented of a longstanding rupture of the rectus femoris muscle at the proximal musculotendinous junction in a semiprofessional soccer player. Its different and unique presentation, the surgical repair, and the remarkable functional recovery are discussed.

Why do some hamstring and quadriceps strains take much longer to repair than others? Which injuries are more prone to recurrence? Intramuscular tendon injuries have received little attention as an element in 'muscle strain'. In thigh muscles, such as rectus femoris and biceps femoris, the attached tendon extends for a significant distance within the muscle belly. While the pathology of most mus...

Aims The locomotory system of fishes is composed of muscles (=myomeres) and myosepta attaching along the vertebral column. Both systems are conflated to the so called musculotendinous system. A myoseptum separates subsequent blocks of muscles and is characterized by a complex 3D arrangement of specific anteriorly and posteriorly pointing cones projected into the musculature. In previous investi...

BACKGROUND Controversy exists on stretching and warm-up in injury prevention. We hypothesized that warm up has a greater effect on Achilles tendon biomechanics than static stretching. This study investigated static stretching and warm-up on Achilles tendon biomechanics in recreational athletes, in vivo. MATERIALS AND METHODS Ten active, healthy subjects, 5 males, 5 females, With a mean age of...

Flexibility is one of the components of physical fitness as well as cardiorespiratory fitness and muscular strength and endurance. Flexibility has long been considered a major component in the preventive treatment of musculotendinous strains. The present study investigated a new aspect of flexibility. Using a cross-sectional study design, we tested the hypothesis that a less flexible body would...
