“…Three previous reports have demonstrated successful cosmetic outcomes of periorbital fractures following plate fixation, using a cuttable bone plate, T-plate, and resorbable plate and tissue expanders. 5,13,14 This case report illustrates the repair of a displaced, comminuted fracture of the right zygomatic process, using a 2.7-mm LCP, which to the authors' knowledge, has not been reported before. LCPs have been used successfully for a variety of fractures 15 and allow complete load bearing across the fracture gap without relying on bone-to-plate friction for stability, subsequently able to withstand higher loads than other plates.…”

“…Tension‐band wiring is frequently used in periorbital fractures, but is unlikely to provide adequate support for comminuted fractures. Three previous reports have demonstrated successful cosmetic outcomes of periorbital fractures following plate fixation, using a cuttable bone plate, T‐plate, and resorbable plate and tissue expanders …”

“…Cases of orbital fractures involving the temporomandibular joint have been described previously. 12,19 The determination of the percentage of true clinical orbital fractures involving the temporomandibular joint would require a retrospective study on naturally occurring orbital fracture configurations. However, clinicians should consider temporomandibular articulation injury such as fractures and fissures in orbital fractures.…”

Objective The aim of this study was to compare the potential of an unshod and shod hoof to cause an orbital fracture in the event of a kick. Materials and Methods Thirty-four equine cadaveric orbitae were exposed to a steel or horn impactor in a dropping test set-up. An impactor velocity of 7 m/s was used for both materials. Testing was repeated on the same orbit at a velocity of 10 m/s with the horn impactor if no damage occurred. A high-speed camera was used to analyse the impact process. Physical parameters (peak force and impact duration) were calculated based on quantitative video-tracking. Computed tomographic (CT) scans were generated and fracture configurations described. Results At 7 m/s, the fracture probability was lower for horn (23.5%) than for steel impactors (70.6%, p = 0.015). On CT-images, damage of the frontal, temporal, zygomatic and lacrimal bones was detected. Furthermore, the orbital socket (17.2%), the supraorbital foramen (34.5%) and the temporomandibular joint (58.6%) were involved. The frequency of affected orbital bones was not significantly different between fractures generated by steel and horn impactors, but the fracture severity was subjectively greater when fractures were generated by steel impactors. Clinical Significance The orbital fracture probability was significantly higher when a kick of a shod versus unshod horse was simulated. This indicates that keeping horses unshod would decrease the injury risk of neighbouring horses when considering group housing systems.

Reconstruction of a Complicated Orbital Depression Fracture with Medial Wall and Globe Repositioning in a Horse: A Collaboration Across Disciplines and Specialties

Abstract: Efforts to restore the medial wall and/or floor of the orbit with concurrent globe repositioning should be considered in horses with severe orbital depression fractures that result in abnormal globe position.
