Contraction velocity of a muscle tendon unit (MTU) is dependent upon the interrelationship between fascicles shortening and the tendon lengthening. Altering the mechanical properties of these tissues through a perturbation such as static stretching slows force generation. Females, who have inherently greater compliance compared with males have slower velocity of MTU components. The addition of a static stretch might further exacerbate this sex difference. The purpose of this study was to investigate the velocity of fascicle shortening and tendon lengthening in males and females during isometric maximal voluntary contraction (MVC) of the plantar flexors prior to and following an acute static stretch...

BACKGROUND: A hamstring autograft is commonly used in anterior cruciate ligament (ACL) reconstruction (ACLR); however, there is evidence to suggest that the tendons harvested may contribute to medial knee instability. HYPOTHESIS: We tested the hypothesis that the gracilis (G) and semitendinosus (ST) tendons significantly contribute to sagittal, coronal, and/or rotational knee stability in the setting of ACLR with a concurrent partial medial collateral ligament (MCL) injury...

Collagen zymography is an SDS-PAGE-based method for detecting both the proenzyme and active forms of collagenases. Although collagen zymography is used for assessment of the matrix metalloproteinases MMP-1 and MMP-13, it can be difficult to detect these collagenases due to technical issues. Moreover, it remains unclear whether the collagenase activity of MMP-8 can be detected by this method. Here, we present an improved collagen zymography method that allows quantification of the activities of MMP-1, MMP-8, and MMP-13...

M Sharabianlou Korth, L B Fritz
CLINICAL/METHODICAL ISSUE: Postoperative imaging of the ankle can be challenging, even for the experienced radiologist. Pathological and postoperative changes to the primarily complex anatomy of the ankle with its great variety of bone structures, tendons, ligaments, and soft tissue in a very limited space may cause great difficulty in differentiating underlying pathology from expected postoperative changes and artifacts, especially in magnetic resonance imaging (MRI). STANDARD RADIOLOGICAL METHODS: Selecting the appropriate radiological modality is key to making the correct diagnosis...

There is currently no method to quantify the quality of the harvested graft before anterior cruciate ligament (ACL) reconstruction. The purpose of the present study was to explore a method for measuring stiffness of the normal tendon of the semitendinosus muscle using shear wave elastography (SWE). Our investigation comprised two steps. First, we determined orientation of the semitendinosus tendon fibers in 20 lower legs of embalmed cadavers. Second, we investigated the feasibility of quantifying stiffness of the normal semitendinosus tendon by SWE in 24 subjects (48 legs: 24 male and 24 female subjects) in vivo...

Thorsteinn H Gudmundsson, Hjalti Mar Bjornsson
INTRODUCTION: The Cunningham technique has been shown to be an effective and simple method to reduce a dislocated shoulder. It is based on the theory that the humeral head remains outside the glenoid fossa due to tension in the long biceps tendon. In the beginning of 2013 doctors at the emergency department in Landspitali University Hospital (LUH) in Reykjavik were instructed in the Cunningham method for reduction of anterior dislocation without sedation. The goal of this retrospective study was to evaluate the impact of its induction with regards to number of attempts, successful relocations, sedation, use of analgesics and length of stay in the ED...

Retinacula are thickenings of deep fascia in the region of joints that hold down the tendons preventing them from bowing out of position. In the region of ankle, number of such retinacula have been described. Retinacula like superior and inferior extensor retinacula have been described which hold down the tendons of leg muscles passing to the foot beneath them. As the extensor tendons of the leg have more distal attachment to the toes, the present study was conducted to ascertain the presence of any additional retinaculum in the mid-foot region, which would tie down the tendons for their effective action at the distal joints...

BACKGROUND: Injury to distal of posterior cord of brachial plexus leads to palsy of the radial and axillary nerves. The symptoms are usually motor deficits of the deltoid muscle, triceps brachii muscle, and the extensor muscles of the wrist, thumb and fingers. Tendon transfers, nerve grafts, and nerve transfers are options of surgical treatment of proximal radial nerve palsy to restore some motor functions. Tendon transfer is painful, requires a long immobilization, and decreases donor muscle strength; nevertheless, nerve transfer produces promising outcome...

The most favorable treatment for acute Achilles tendon ruptures remains controversial. In particular, three key questions are intensively debated: is operative or non-operative treatment superior? If surgery is performed, should open or minimally invasive percutaneous techniques be used? How should the follow-up treatment be carried out? The aim of this article is to answer these essential questions based on the currently available evidence. Non-operative treatment leads to a higher rate of re-ruptures and inferior functional results when compared to operative treatment...

In terrestrial locomotion, muscles undergo damped oscillations in response to limb impacts with the ground. Muscles are also actuators that generate mechanical power to allow locomotion. The corresponding elementary contractile process is the work stroke of an actin-myosin cross-bridge, which may be forcibly detached by superposed oscillations. By experimentally emulating rat leg impacts, we found that full activity and non-fatigue must meet to possibly prevent forcible cross-bridge detachment. Because submaximal muscle force represents the ordinary locomotor condition, our results show that forcible, eccentric cross-bridge detachment is a common, physiological process even during isometric muscle contractions...
