A pivot joint (trochoid joint, rotary joint, Lateral Ginglymus) is a type of synovial joint.In pivot joints, the axis of a convex articular surface is parallel with the longitudinal axis of the bone.ivot joints allow for rotation, protraction, retraction,twist, flexion, extension, adduction and abduction, which can be external (for example when rotating an arm outward), or internal (as in rotating an arm inward). When rotating the forearm, these movements are typically called pronation and supination.
1 The term Pivot is sometimes used to describe a turn on the hindquarters of up to 360 degrees where the horse has to keep a rear pivot foot stationary. 2  In 4-H competition, pivots of 90, 180, or 360 degrees are sometimes used in pattern classes to introduce youth riders to reining concepts. Circles: the horse must perform large, fast circles at a near-gallop and smaller, slow circles at a lope. 2  They should be perfectly round, with the rider dictating the pace of the horse. 3  There should be an easily seen change of speed as the rider transitions from the large, fast to the small, slow circles.
