0014influence of mechanical simulators on reverse shoulder prosthesis with simultaneous enhancements...
DESCRIPTION
As the mean age of the population increases, degeneration of their joints, cartilages and musclesincreases as well. Vast number of people need joint replacement to maintain their normal jointfunctionality. Rotator cuff tear and degenerative diseases cause severe pain and shoulder jointinstability. To restore the joint stability, the joint replacement is commonly performed. In somecases, with the anatomic joint replacement, rotator cuff may not control the range of motion and theprosthesis may fail. Therefore, using reverse shoulder joint prosthesis can increase the stability andimprove the function of the joint. Reverse shoulder arthroplasty is growing in popularity for patientswith deficient rotator cuffs; however, the phenomenon of scapular notching continues to be aconcern. This project examined the effects of using mechanical simulators to predict the notchingand impingement between the implant components. It is clear that by utilizing mechanical simulatorswhich can perform adequate kinematic freedom such as AMTI these problems can be solved.Simulators vary in their level of sophistication, however the AMTI joint simulator plays an importantrole in preclinical validation of orthopedic implants. Simulator tests can be used to conductaccelerated protocols that simulate particularly extreme conditions, thereby establishing the limits ofperformance for the material. The division for biomechanics is engaged to develop a highperformance6 DOF biomechanical joint analysis system based on industrial robots. The roboticsystem may be thought as a testing machine that can predict the possible failure of joint implants.TRANSCRIPT

Influence of mechanical simulators on reverse shoulder prosthesis with simultaneous enhancements in DOF and COR
As the mean age of the population increases, degeneration of their joints, cartilages and muscles increases as well. Vast number of people need joint replacement to maintain their normal joint functionality. Rotator cuff tear and degenerative diseases cause severe pain and shoulder joint instability. To restore the joint stability, the joint replacement is commonly performed. In some cases, with the anatomic joint replacement, rotator cuff may not control the range of motion and the prosthesis may fail. Therefore, using reverse shoulder joint prosthesis can increase the stability and improve the function of the joint. Reverse shoulder arthroplasty is growing in popularity for patients with deficient rotator cuffs; however, the phenomenon of scapular notching continues to be a concern. This project examined the effects of using mechanical simulators to predict the notching and impingement between the implant components. It is clear that by utilizing mechanical simulators which can perform adequate kinematic freedom such as AMTI these problems can be solved. Simulators vary in their level of sophistication, however the AMTI joint simulator plays an important role in preclinical validation of orthopedic implants. Simulator tests can be used to conduct accelerated protocols that simulate particularly extreme conditions, thereby establishing the limits of performance for the material. The division for biomechanics is engaged to develop a high-
6performance DOF biomechanical joint analysis system based on industrial robots. The robotic system may be thought as a testing machine that can predict the possible failure of joint implants.
