Topic:Metatarsal Bones
Metatarsal bones in horses are a group of long bones located in the hind limbs, extending from the tarsal bones to the phalanges. These bones play a role in supporting weight and facilitating locomotion. The equine metatarsus typically comprises the third metatarsal bone, also known as the cannon bone, and the second and fourth metatarsal bones, referred to as splint bones. The structure and health of these bones are significant for the overall mobility and performance of the horse. This page compiles peer-reviewed research studies and scholarly articles that explore the anatomy, function, and clinical considerations of metatarsal bones in equine physiology.
Surgical approaches to certain long bones of the horse for application of tension band plates. In the horse, surgical approaches for plating fractures of the ulna, radius, metacarpus, tibia, and metatarsus involved a single curvilinear skin incision and incision of the superficial fascia in a manner to prevent postoperative dehiscence. The tension side of the bones, as well as location of nerves, arteries, veins, and muscles, were the major determinants in developing these approaches for atraumatic surgery and short operative time.
In vivo measurement of bone strain in the horse. Strain gauges were successfully bonded in vivo to the cranial, caudal, medial, and lateral aspects of the equine radium and tibia and to the dorsal, palmar, or plantar, medial, the lateral aspects of the metacarpus and metatarsus--all in the mid-diaphyseal region. Various activities were investigated, including walking, trotting or pacing, and standing up from anesthesia. The strain patterns showed that each stride produced a characteristic deformation cycle. The strains were measured and the axial loads were calculated as the horse performed certain activities. The tension band side of each b...
