Linked Total Elbow Arthroplasty

Linked total elbow arthroplasty (TEA) is differentiated from unlinked arthroplasty by virtue of the captured articulation of the humeral and ulnar components. This physical linkage provides distinct advantages compared with implants where no linkage exists. However, there are some theoretic disadvantages as well. There are several linked implant systems in use in the USA. Each implant system shares the common feature of being linked and possessing a degree of laxity. However, there are unique design features of each system. Unfortunately, there is no available data comparing the outcomes using different systems. The results of linked TEA will be reviewed with particular attention to the underlying pathology. This will highlight the conditions where available implants perform well and conditions that continue to challenge current implants.
