Since the late 2000’s, new total and hemi elbow replacement prostheses (TER & HER) have been designed (Conzemius, Acker – van Der Muellen and Innes [TER] / Wendelburg – Tepic [HER]) for the treatment of intractable end-stage canine elbow osteoarthritis (OA) as well as early so called “medial compartment disease”. While most systems remain cemented, unlinked, semi-constrained stemmed designs, a novel TER system (TATE Elbow) has been devised by Acker and van Der Meulen. This proceeding, focuses on the TATE Elbow prosthesis, describes recent modifications in implant design, surgical technique and instrumentation, and summarizes clinical results and complications.
