the musculoskeletal extrapulmonary tuberculosis is uncommon, the upper extremity tuberculosis is not common and the mycobacterial involvement of skin of hands and synovial sheath of tendons is rare. this prospective observational study was undertaken between august  2014 and december 2015 in a tertiary referral hospital. patients attending with suspected primary tuberculosis of soft tissue of t...

Stem cells have been widely used in tendon tissue engineering. The lack of refined and controlled differentiation strategy hampers the tendon repair and regeneration. This study aimed to find new effective differentiation factors for stepwise tenogenic differentiation. By microarray screening, the transcript factor Fos was found to be expressed in significantly higher amounts in postnatal Achil...

conclusions we feel this rare, currently unclassified variant of a tibial tubercle avulsion fracture should be recognised and consideration taken to adding it to existing classification systems. introduction a sleeve fracture classically describes an avulsion of cartilage or periosteum with or without osseous fragments and usually occurs at the inferior margin of the patella. tibial tubercle sl...

Overuse related tendon pain is a significant problem in sport and can interfere with and, in some instances, end an athletic career. This article includes a consideration of the biology of tendon pain including a review of tendon anatomy and histopathology, risk factors for tendon pain, semantics of tendon pathology, and the pathogenesis of tendon pain. Evidence is presented to guide the physic...

Although conditioning is routinely used in mechanical tests of tendon in vitro, previous in vivo research evaluating the influence of body anthropometry on Achilles tendon thickness has not considered its potential effects on tendon structure. This study evaluated the relationship between Achilles tendon thickness and body anthropometry in healthy adults both before and after resistive ankle pl...

In vitro cell studies might be a useful tool for studying tendon pathology, but no suitable in vitro models exist for tendon disorders. The purpose of this study was to confirm whether cell scratch culture using tendon-derived fibroblasts can provide a suitable in vitro tendon disorder model. Extracellular matrix components were examined immunohistochemically in tendon tissue, and then their re...

INTRODUCTION: A tendon graft is indicated when a flexor tendon repair fails, or when tendon rupture or tendon transfer requires prolongation of the muscle-tendon unit. The effect of hyaluronic acid (HA) on flexor tendon repair has been investigated in many animal and clinical studies. Exogenously applied HA may prevent adhesion formation between the flexor tendon and surrounding tissue followin...

twelve left camel forelimbs were collected, and ultrasonography was performed at five different levels around the metacarpal region. limbs were then cut in the transverse plane at levels corresponding to the ultrasound images. transverse and sagittal plane images were taken at each of the five levels, keeping all ultrasound imaging factors constant. echogenicity, diameter, width and cross secti...

BACKGROUND Ultrasonography has been widely applied for in vivo measurements of tendon mechanical properties. Assessments of human Achilles tendon mechanical properties have received great interest. Achilles tendon injuries predominantly occur in the tendon region between the Achilles-soleus myotendinous junction and Achilles-calcaneus osteotendinous junction i.e. in the free Achilles tendon. Ho...

The elastic properties of the human Achilles tendon are important for locomotion; however, in vitro tests suggest that repeated cyclic contractions lead to tendon fatigue - an increase in length in response to stress applied. In vivo experiments have not, however, demonstrated mechanical fatigue in the Achilles tendon, possibly due to the limitations of using two-dimensional ultrasound imaging ...
