BACKGROUND Palmar region of metacarpus in the horses and donkeys is an important region because of its tendons and ligaments which contribute to stay apparatus. This study was done on forelimbs of 6 healthy Miniature donkeys to detect the tendons, ligaments and their accessories on the palmar surface of metacarpus in this animal. MATERIALS AND METHODS Based on that magnetic resonance imaging ...

Single Fe adatoms and clusters of Fe adatoms on graphene are studied through first-principles calculations using density functional theory (DFT) and spin density functional theory (sDFT). First, we consider computational cells containing various numbers of C atoms and one Fe adatom. We calculate the binding energy, adatom height, and magnetic moment of the adatom above a few high-symmetry posit...

Abstract While the ground state of magnetic materials is in general well described on basis spin density functional theory (SDFT), theoretical description finite-temperature and non-equilibrium properties require an extension beyond standard SDFT. Time-dependent SDFT (TD-SDFT), which give for example access to dynamical are computationally very demanding can currently be hardly applied complex ...

background: sdft, ddft and suspensory ligament are the most important tendons and ligament of the palmar aspect of the metacarpus that contribute to stability mechanism. objectives: the purpose of this study was to describe the tendons and ligaments of the palmar surface of metacarpus in anatoly donkey and compare them with those in horse. methods: 14 healthy anatoly donkeys without lameness we...

OBJECTIVE To compare in vitro biomechanical properties of a novel suture pattern to a current standard for primary repair of equine superficial digital flexor tendon (SDFT) laceration. STUDY DESIGN In vitro randomized, paired design. ANIMALS Cadaveric equine forelimb SDFT (n = 24). METHODS The 3-loop pulley (3LP) and 6-strand Savage (SSS) suture patterns were applied to transected equine ...

A nonlinear elastic microstructural model is used to investigate the relationship between structure and function in energy-storing and positional tendons. The model is used to fit mechanical tension test data from the equine common digital extensor tendon (CDET) and superficial digital flexor tendon (SDFT), which are used as archetypes of positional and energy-storing tendons, respectively. The...

The superficial digital flexor tendon (SDFT) is one of the longest tendons in the horse. In racehorses, disturbance of the locomotor functions of the SDFT occurs most frequently in the central area of the mid-metacarpal region. While many studies have investigated the equine SDFT, there are no reports to date of the morphological characteristics of collagen fibrils in the central and peripheral...

Is there still a role for surgery? Yes, surgical management continues to play an important role in the management of all horses with injuries to the superficial digital flexor tendon (SDFT), in both racehorses and sports horses. Intralesional therapy has certainly progressed and there are numerous options for augmenting repair of damaged SDFT. Regenerative therapy continues to improve and with ...

Little is known about the rate at which protein turnover occurs in living tendon and whether the rate differs between tendons with different physiological roles. In this study, we have quantified the racemization of aspartic acid to calculate the age of the collagenous and non-collagenous components of the high strain injury-prone superficial digital flexor tendon (SDFT) and low strain rarely i...

REASONS FOR PERFORMING STUDY Although track surfaces are a risk factor of tendon injuries, their effects on tendon loading at high speed are unknown. Using a noninvasive ultrasonic technique, it is now possible to evaluate the forces in the superficial digital flexor tendon (SDFT) in exercise conditions. OBJECTIVES To compare the effects of an all-weather waxed track (W) vs. a crushed sand tr...
