The equine lameness evaluation video is authored by Professor Gary M. Baxter, VMD, MS, DACVS. This video series describes and illustrates how to perform a lameness evaluation in a lame horse. Examination of a horse at the walk, straight trot, and when circled is demonstrated together with all flexion tests of the forelimbs and hindlimbs. Proper positioning for diagnostic flexion tests is described and demonstrated. Examples of specific types of musculoskeletal abnormalities (upward fixation of the patella, stringhalt, peroneus tertius rupture, fibrotic myopathy, forelimb paddling, and hind limb plaiting) are demonstrated using clinical cases. In addition, 7 horses with forelimb lameness and 7 horses with hind limb lameness problems have been included to demonstrate what clinical parameters the author looks for when observing horses with forelimb vs hindlimb lameness.
