Table 2: Advantages and Disadvantages of Linked and Unlinked Prosthesis

	Linked	Unlinked
Advantages	Ensure joint stability May be used in the presence of ligamentous insufficiency May be used in the presence of severe bone loss Better range of motion (soft-tissue release and non-anatomic implantation)	Less constrained implants may be associated with a lower risk of wear, loosening and osteolysis Less bony-invasive, which may be beneficial if revision or resection are required Some anatomic humeral components may be used as hemiarthroplasty
Disadvantages	Increased constrained may result in increased tension to the interface and higher risk of mechanical failure secondary to wear and/or loosening More extensive canal invasion, potentially complicating revision surgery Cannot be used as hemiarthroplasty Component linking may make implantation more difficult Possible failure of the linking mechanism	Most require more accurate component positioning in order to ensure proper articular tracking It is possible to subluxate or dislocate the joint Difficult to use when there is the need to compensate for bone loss or ligamentous insufficiency Limited ability for soft-tissue release or non-anatomic implant positioning in patients with stiffness
