Arthroscopic Anatomy of the Equine Temporomandibular Joint

Abstract

Conditions affecting the lateral and caudal aspects of the dorsal compartment of the TMJ should be visible by arthroscopy.

Does temporomandibular joint pathology affect performance in an equine athlete?

“…The dorsal and ventral compartments do not appear to communicate (May et al . ; Rodriguez et al . ), although one previous cadaver study showed communication (Rosenstein et al .…”

“…The parotid salivary gland is in close proximity to the joint and may overlie the caudal part of the joint (May et al . ; Rosenstein et al . ).…”

Functional anatomy of the equine temporomandibular joint: Collagen fiber texture of the articular surfaces

“…Concomitantly, several studies have been performed to evaluate the suitability and potential relevance of advanced imaging techniques, i.e. radiography (Ebling et al, 2009), computed tomography (Rodríguez et al, 2008;Carmalt et al, 2016), ultrasonography (Rodríguez et al, 2007), magnetic resonance imaging (Rodríguez et al, 2010) and TMJ-arthroscopy (May et al, 2001;Weller et al, 2002). Besides these diagnostic and gross anatomical investigations, functional examinations of the equine masticatory movements have been performed.…”

Clinically significant, nontraumatic, degenerative joint disease of the temporomandibular joints in a horse

“…Due to the nondescript signs, it is possible that cases of TMJ‐DJD are either missed or incorrectly diagnosed (May et al . ; Rodriguez et al . ).…”

“…In both horses and people, a common cause of TMJ‐DJD is trauma, which can lead to fracture of the mandibular condyle, disrupting the articular surface (May et al . ; Carmalt and Wilson ; Rodriguez et al . ; He et al .…”
