Research at Michigan State University indicates the pastern joint undergoes a larger range of motion than previously realized. Hilary Clayton told attendees at the recent American Association of Equine Practitioners (AAEP) annual meeting that the forelimb pastern joint flexed 35 degrees during the stance phase of the trot. She says much of the rotation in the distal limb that had previously been credited to the coffin joint is actually occurring at the pastern joint.
With a half dozen trotting horses, maximal 155 degree flexion occurred at 34 percent stance and maximal extension of 190 degrees took place at 92 percent stance. “The fact that the pastern joint undergoes a significant amount of flexion during the braking phase may offer an explanation for the rather high incidence of pastern joint arthritis with horses used in sports that involve rapid deceleration,” says Clayton.
