PURPOSES To assess the tensile strength of the modified 4-strand cruciate technique for obliquely lacerated tendons, and to compare the findings with the strength of transversely lacerated tendons repaired at various grasping depths. METHODS 60 porcine front foot tendons were evenly divided into 4 groups. In groups 1 to 3, tendons were transversely lacerated and repaired with grasping points ...

BACKGROUND The use of plasma rich in growth factors (PRGF) has been proposed to improve the healing of Achilles tendon injuries, but there is debate about the effectiveness of this therapy. The objective of the present study was to evaluate the histological effects of PRGF, which is a type of leukocyte-poor platelet-rich plasma, on tendon healing. METHODS The Achilles tendons of twenty-eight ...

The predominant function of tendons is to position the limb during locomotion. Specific tendons also act as energy stores. Energy-storing (ES) tendons are prone to injury, the incidence of which increases with age. This is likely related to their function; ES tendons are exposed to higher strains and require a greater ability to recoil than positional tendons. The specialized properties of ES t...

Injured rat Achilles tendons were treated with botulism toxin to create a mechanically unloaded condition (unloaded) or left untreated (loaded), and then treated with phosphate-buffered saline (PBS), platelet-rich plasma (PRP), tendon stem cells (TSCs), or a combination (TSCs + PRP). mRNA and protein expression of collagen I, collagen III, tenascin C, and Smad 8 were determined by real time PCR...

10.1083/jcb/1722fta2jcb1722fta2Mitch [email protected] aking tendons C ells are fastidious about their internal conditions. But for scientists trying to decipher how collagen forms structures such as tendons and the cornea, the big question 30 years ago was how much control cells exert over their surroundings. In a tendon, for example, colla...

results the overall prevalence of right, left, bilateral and total absence of the palmaris longus were 4.1%, 5.2%, 3.9% and 13.2%, respectively. there was no significant difference in its absence with regard to the body side or gender (p > 0.05). background the palmaris longus is a degenerating weak flexor muscle in the anterior of the forearm. many techniques for clinically determining the pre...
