Scapular notching – an erosive lesion of the inferior scapular neck because of the impingement of the humeral implant during adduction – is a common radiographic finding occurring after reverse total should arthroplasty. The clinical importance of notching is unclear, and the optimal treatment of severe notching is unknown.
The incidence and severity of scapular notching is related to prosthetic design and surgical technique. Implant design factors include size, shape, and position of the glenosphere, inclination of the humeral neck-shaft angle, implant offset, and native scapular anatomy. Scapular notching may lead to deterioration of functional outcomes and glenoid implant loosening and failure. Lateral offset, inferior glenosphere overhang, and careful consideration of the presurgical glenoid morphology may help prevent scapular notching. Currently, there is limited evidence to direct the management of scapular notching, and further research is needed to elucidate optimal prevention and treatment strategies.
Join the authors of “Scapular Notching in Reverse Total Shoulder Arthroplasty” published in the March 15, 2019 issue of JAAOS as they share what is known about this common radiographic finding. Participants are invited to an open Q&A with the authors and interactive survey questions at the end of this 60-minute live webinar.
