This case study aims to take the reader through a lameness work up in a step-by-step manner and justify the clinical decisions made at each stage.

Case history

A 14-year-old gelding used for general purpose riding was presented for further investigation of right hindlimb lameness, which had not responded to a course of non-steroidal analgesia and three months of box rest. He had also been undergoing treatment for mud fever of both hindlimbs.
