Additionally, horses with a hind limb lameness will tend to reduce the degree of leg use. To do so, some horses will reduce the contraction time of the gluteals on the side of the lame leg, leading to a "hip roll" or "hip dip" and appearance that the hip drops a greater degree on the side of the lame leg.

Irregular bones: Protect the central nervous system. The vertebral column consists of irregular bones. Sesamoid bones: Bones embedded within a tendon. The horse's proximal digital sesamoids are simply called the "sesamoid bones" by horsemen, his distal digital sesamoid is referred to as the navicular bone.
Curb as a visible blemish is an easy diagnosis, as swelling in the distal lateral hock region is, by definition, curb. However, ultrasound is an essential tool in the diagnosis and in establishing a treatment plan. Diagnostic anesthesia (local or nerve blocks) can be helpful, but is not perfectly specific in this area.
Horses have 205 bones, which are divided into the appendicular skeleton (the legs) and the axial skeleton (the skull, vertebral column, sternum, and ribs). Both pelvic and thoracic limbs contain the same number of bones, 20 bones per limb. Bones are connected to muscles via tendons and other bones via ligaments.
The limbs of the horse are structures made of dozens of bones, joints, muscles, tendons, and ligaments that support the weight of the equine body. They include two apparatuses: the suspensory apparatus, which carries much of the weight, prevents overextension of the joint and absorbs shock, and the stay apparatus , which locks major joints in ...

Fairly commonly injured by horses doing fast work, the DDFT is round in cross section. Superficial digital flexor: Runs down the back of the leg, behind the carpus and cannon, branches below the fetlock and inserts into the distal side of the 1st phalanx and proximal side of the 2nd phalanx. Flexes the elbow, carpus and lower joints.
The nerves that compose the cauda equina innervate the pelvic organs and lower limbs to include motor innervation of the hips, knees, ankles, feet, internal anal sphincter and external anal sphincter. In addition, the cauda equina extends to sensory innervation of the perineum and, partially, parasympathetic innervation of the bladder. [1]
