Topic:Skeleton
The equine skeleton is a complex structure composed of bones, joints, and connective tissues that provide support, protection, and mobility to the horse. It consists of approximately 205 bones, which include the skull, spine, ribs, and limbs. The skeletal system plays a vital role in locomotion, as it serves as the framework for muscle attachment and facilitates movement. Additionally, it protects vital organs and stores essential minerals such as calcium and phosphorus. The shape and conformation of the skeleton can influence a horse's performance and susceptibility to injury. This page compiles peer-reviewed research studies and scholarly articles that explore the anatomy, development, and biomechanics of the equine skeleton, as well as its impact on equine health and performance.
Influence of microarchitecture on stressed volume and mechanical fatigue behaviour of equine subchondral bone. Fractures of the equine metacarpophalangeal (MCP) joint are among the most common and fatal injuries experienced by racehorses. These bone injuries are a direct result of repetitive, high intensity loading of the skeleton during racing and training and there is consensus that they represent a mechanical fatigue phenomenon. Existing work has found the fatigue life of bone to be strongly determined by bone microarchitecture and the resulting stressed volume (i.e., the volume of bone stressed above assumed yield). The purpose of this study was to quantify the influence of bone microarchitecture o...
Pathological Changes in Early Medieval Horses from Different Archaeological Sites in Poland. The work is the first comprehensive analysis of equine pathological changes from the Polish territory. The research material was collected from 20 archaeological sites, mainly early medieval settlements, such as strongholds, settlements, towns and horse graves. In the material examined, 186 cases of lesions were found. Of these, 26.9% were lesions of the spine, 39.8% lesions of the limb skeleton and 31.7% lesions of the head including dental pathologies. Most of the lesions in the limbs involved their distal segments. The vast majority of pathological cases can be linked to animal use. It was ...
Effect of clodronate on gene expression in the peripheral blood of horses. There are two FDA-approved bisphosphonate products, clodronate (Osphos®) and tiludronate (Tildren®), for use in horses. It is hypothesized that bisphosphonates can produce analgesic effects and prevent proper healing of microcracks in bone. Therefore, bisphosphonate use is banned in racehorses. However, bisphosphonates have a short detection window in the blood before sequestration in the skeleton, making the reliability of current drug tests questionable. Seven exercising Thoroughbred horses were administered clodronate (1.8 mg/kg i.m.), and four were administered saline. RNA was isolated...
Chiropractic effects on stride parameters and heart rate during exercise in sport horses. Equine veterinarians performing chiropractic treatments are frequently asked to evaluate and treat sound horses to improve their performance and address pain associated with the axial skeleton. Studies describing the effects and mechanisms of chiropractic treatments in horses without overt lameness are scarce. Objective: This study aimed to evaluate the effect of chiropractic treatments on stride rate, length, symmetry, heart rate and rider-perceived quality of the ridden work in sport horses. Methods: A blind randomised controlled trial with crossover design. Methods: Thirty-eight horses ridd...
[The discovery of a horse skeleton from the 17th century in Kiesen in Bern canton]. In 1968 a skeleton of a horse was found in Kiesen (Switzerland). This discovery could be dated by radiocarbon method: According to that this 13 years old gelding with a withers-height of 135 to 140 cm must have lived during the first third of the 17th century. Apparently it died by an accident. The bones are fully documented with pictures and scales and the findings described and discussed in detail.
The lead status of horses from central Europe depending on breed, sex, age and living area. The breed of horses took a significant effect on the Pb content of animals with a normal Pb supply. Warm-blooded horses stored more Pb in skeleton, kidneys, liver and cerebrum than heavy horses. The sex only had the trend of influencing the Pb status. Mares with a normal Pb supply incorporated more Pb than geldings. Age only took a slight effect on the skeleton. Older horses stored more Pb in the metatarsal bone than younger ones. The Pb content of horse meat was not influenced by Pb exposure. Pb was not additionally deposited in the musculature. The Pb offer of the living area took a signific...
