Assessing proximal humerus cortical bone thickness for total shoulder arthroplasty: A cadaveric study

In reverse total shoulder arthroplasty, a humeral osteotomy is typically performed at the anatomic neck. The quality and quantity of cancellous and cortical bone impacts sizing of implants. Little-to-no information exists characterizing the transition of this bone quality at this location. This cadaveric study focused on measuring and analyzing the transition zone of the proximal humerus bone quality to better understand the implications of utilizing different implant sizes during reverse total shoulder arthroplasty. This assessment was conducted through the usage of a newly designed indentation depth probe.
