Summary
# Editorial Summary: Septic Arthritis and Osteomyelitis of the Temporomandibular Joint in an Equine Case Traumatic injuries to the equine head can result in serious secondary infections involving bone and joint structures, yet septic osteomyelitis of the temporomandibular joint (TMJ) remains an uncommon clinical presentation. Balducci and colleagues document the management of a 1-year-old Quarter Horse gelding presenting with concurrent septic arthritis and osteomyelitis of the TMJ, using computed tomography (CT) imaging to characterise the lesions and direct surgical planning prior to arthrotomy and curettage. The case report demonstrates the critical role of advanced imaging in identifying bone sequestra and joint involvement, which guided definitive surgical intervention and medical management. Whilst individual case reports have limited evidence strength, this work provides valuable clinical guidance for practitioners managing complicated infections in the equine head—particularly in younger horses where aggressive treatment may be warranted to preserve function and prevent chronic complications. The findings underscore the importance of early imaging and referral for specialist orthopaedic assessment in traumatic mandibular injuries with signs of persistent infection or lameness of the jaw.

Practical Takeaways
- •CT imaging should be utilized for temporomandibular joint infections to accurately identify bone sequestra and guide surgical approach
- •Arthrotomy with aggressive curettage is a viable treatment option for septic TMJ osteomyelitis in young horses
- •Early surgical intervention combined with appropriate medical management can achieve favorable outcomes in this typically challenging condition
Key Findings
- •Arthrotomy with curettage of the temporomandibular joint successfully managed septic osteomyelitis and arthritis in a 1-year-old Quarter Horse gelding
- •Computed tomography provided detailed assessment of lesions within the temporomandibular joint and effectively guided surgical planning
- •Combined surgical debridement and medical management resulted in successful clinical outcome
