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.

The main findings on dynamic evaluation were:

  • a. Hyper -flexion of the right hind at walk and moderate bilateral hindlimb lameness on a straight line at trot
  • b. Hyperextension of the right hindlimb, moderate right hindlimb lameness at trot in a straight line at trot
  • c. No detectable compromise at the walk other than hyperflexion
  • d. Sound at the walk, mild left hindlimb lameness at the trot


1. The main abnormalities identified on clinical examination were:

  • a. Pelvic asymmetry with associated gluteal muscle atrophy
  • b. Upright hindlimb conformation with increased angles at hock and stifle
  • c. Muscle atrophy over the right hindquarters and hyperflexion of the right metatarsophalangeal (MTP) joint
  • d. Muscle atrophy of the right hindquarters with hyperextension of the right metatarsophalangeal joint.
