The subscapularis tendon, coracohumeral ligament, and transverse humeral ligament are all believed to contribute to biceps tendon stability within the bicipital groove. In order to examine the relative contribution of these soft tissue structures to proximal biceps tendon stability, 11 fresh frozen cadaveric shoulder specimens were prepared and mounted onto a custom jig. A three-dimensional dig...

Supraspinatus tendon tearing is one of the most common causes of the shoulder pain and dysfunction, which often requires a surgical repair. In this situation, proximal tendon stump is usually retracted medially from its original insertion. For successful reduction of the retracted tendon stump to its original insertion, the elasticity of the tendon-muscle unit should be preserved by the time of...

Background Ultrasonographic abnormalities of the patellar tendon frequently occur in asymptomatic athletes and it is not always clear whether they precede (and may predict) the development of tendinopathy. Objective This study aimed to investigate by ultrasonography the prevalence of patellar tendon abnormalities in players of "pallapugno" and to establish whether structural tendon abnormalit...

A guided tendon concept in the context of rotating helicopter blades is proposed to modify their dynamic characteristics, so that rotorcraft can operate under a wide range working conditions. In this paper, pre-twisted beam with bending-bending-torsion coupling axially loaded by used model system. An internally attached at several spanwise locations avoid resonant vibrations due insufficient se...

Unlike the inverse kinematics problem of n-tendon continuum robots, forward lacks a closed-form analytical solution. In this paper, novel algorithm for single-segment flexible robots is developed that can determine resulting beam configuration any given set actuator displacements. The determines key parameters all possible n- to 1-tendon combinations and examines them against evaluation criteri...

BACKGROUND There has been no published report assessing the mechanical properties of a repaired Achilles tendon after surgery using shear wave elastography (SWE). The aim of this study was to investigate the changes in mechanical properties of the healing Achilles tendon after surgical repair of a tendon rupture using ultrasound SWE and how these changes correlate with tendon function. MATERIAL...

BACKGROUND The purpose of this investigation was to evaluate if clinical assessment, Ultrasound + Colour Doppler (US + CD) and Ultrasound Tissue Characterisation (UTC) can be useful in detecting plantaris tendon involvement in patients with midportion Achilles tendinopathy. METHODS Twenty-three tendons in 18 patients (14 men, mean age: 37 years and 4 women: 44 years) (5 patients with bilatera...

Abaamet The wound healing process of New Zealand rabbit extensor digitorum communis tendon was studied from the fifth through th&ecnth post-surgical day by concurrent observation of physical, mechanical, and biochemical properties. Me&an&l testing was by isometric thcrmic denaturation followed by biochemical assay of tendon and the physiological saline bathing medium for collagen protein and ac...
