• Abstract:

  We report the clinical case of a nine-year-old quarter horse, used for charrería activities, that presented with progressive lameness of the right forelimb with a twelve-month history. Orthopedic examination revealed dorsal swelling in the pastern region and pain on digital flexion. Perineural blocks allowed the lesion to be localized in the proximal interphalangeal joint. Radiographic examination showed loss of joint space, subchondral sclerosis, and osteophyte formation, findings consistent with advanced degenerative joint disease. Given the limited response to conservative medical treatment and the chronic nature of the condition, surgical rthrodesis was performed by placing three parallel cortical compression screws following destruction of the articular cartilage. The postoperative course was satisfactory, with no complications and no lameness at the three-month follow-up. This report highlights the importance of accurate clinical and imaging diagnosis and supports arthrodesis as a viable therapeutic alternative in horses with advanced degenerative joint disease of the proximal interphalangeal joint.
