Arthroscopic treatment of temporomandibular joint sepsis in a horse

Objective-To report arthroscopic debridernent and lavage of a septic temporomandibular joint (TMJ) in a horse. Design-Clinical case report. Animals-A 12-year-old Thoroughbred mare. Methods-Arthroscopic investigation of the dorsal joint pouch of the right TMJ was made through a stab incision into the dorsocaudal compartment. Mechanized resection Of synovium and fibrinous debris combined with copious lavage, and intra-articular and systemic antibiotic administration was used to treat the septic TMJ. Results-Arthroscopic debridernent and lavage of the TMJ, in combination with intra-articular and systemic antimicrobials resulted in resolution of sepsis. Eight months post-operatively, there was no clinical evidence of degenerative joint disease or ankylosis of the TMJ. Conclusion-TMJ sepsis is rare in horses, however, standard arthroscopic equipment can be used in the management of this condition with minimal complications. Clinical Relevance-Arthroscopic debridement and lavage should be considered for evaluation and initial treatment of TMJ sepsis in horses.
