The primary development goal was to significantly reduce the complication rates reported with all previous reverse shoulder arthroplasty (rTSA) prosthesis designs, including: scapular notching, instability/dislocation, aseptic glenoid and humeral loosening, lack of active internal/external rotation, acromial/scapular fractures, and deltoid-fatigue.
Surgical site infection is one of the most common and expensive post-operative complications to manage in shoulder arthroplasty.
A recent article from Denard and Ladermann looked at the difference in ROM, VAS pain scores and ASES scores between differing post-op protocols of immediate motion and delayed motion.
The authors reported on 19 patients with 20 total shoulders with minimum two-year follow-up using an augmented glenoid component. They hypothesized the need for augmented glenoids as a way to save bone and prevent medializing the joint line.
The authors conducted a study to measure a subjective questionnaire that reported type of activities, range of motion, pain and strength. The authors looked at patients younger and older than 65 to determine if there was a difference in activity levels and what the functional differences were in these patient populations.
This study reviewed comorbidities and results for higher baseline American Shoulder and Elbow Surgeons (ASES) scores that are correlated with poor post-operative improvement.
This study focused on the effects and risks of bilateral reverse shoulder arthroplasty (rTSA) on internal rotation (IR) in 57 patients. Data was recorded up to two years after the second surgery.
These authors studied the ability to implant a custom glenoid component in 10 cadaver glenoids with glenoid defects using patient-specific guides and traditional non-guided techniques.
