fetlock
the anatomy of the forelegs begin at the scapula. this is the shoulder in which provides the ease of movement as it is connected to various bones surrounding it such as the cervical vertebra (a section of the spine). the next bone is the humerus which leads onto the radius below. the radius is then connected to the bones of the knee. the carpus is located at front of the knee and the pisiform is the back of the knee. below the knee is the cannon bone which is also known as the 3rd metacarpal. 55 million years ago when the eohippus existed, the cannon bone used to be the 3rd toe of the foot. its fusion took place in order to increase height and power of the limb. behind the cannon bone are the splint bones. the splint bones are also known as the 2nd and 4th metacarpal and fused 25 - 35 million years ago during the time of the miohippus. they provide extra strength and support of the cannon bone and used to be the 2nd and 4th toes of the foot. below the cannon bone is the fetlock joint in which lays a structure if many bones. firstly are the sesamoid bones that act as part of the system that allows the leg to drop as pressure is applied and spring back up as pressure is released. below this is the proximal phalanx also known as the long pastern which is followed by the middle phalanx (short pastern). below these bones are the navicular bone and the distal phalanx. the distal phalanx can be known as the coffin bone or the pedal bone. below the navicular bone is the navicular bursa.

sensing that something was wrong with the horse, jockey chris antley eased charismatic up in the final furlong, jumped off right after the finish line and then held up the colt's left front leg. charismatic's foreleg had fractured in multiple places involving the cannon bone and sesamoids, and antley's actions probably saved his life by avoiding a more catastrophic injury. as it was, the horse was taken off the track in a van and underwent surgery the next day. his surgeon stephen selway said, "the fracture [of the cannon bone] happened first. as the horse went on, the damaged piece hit the sesamoids and caused them to fracture." the damaged area of the cannon bone extended about six inches: four screws were inserted to provide stability. there was no sign of pre-existing injury.
