Abstract
Shoulder arthroplasty is regularly performed in patients with arthritis degeneration to regain their own shoulder functions. Arthritis shoulder often link to glenoid deformation, especially posterior wear resulting in glenoid retroversion. To reconstruct severely retroverted glenoid, placing glenoid prosthesis has been performed. The use of cementless glenoid prosthesis with porous surface has been introduced to shoulder arthroplasty since this enhances bone ingrowth and maximizes fixation. However, research in the success of cementless glenoid prosthesis following arthroplasty in retroverted glenoid has been rarely reported. In this study, we aimed to investigate two different approaches of using cementless glenoid prosthesis, standard and wedged component designs. Finite element method was conducted to compare micromotions obtained from the two approaches. The results showed that the wedged component seemed to be an appropriate approach for reconstructing retroverted glenoid due to the small micromotions obtained. Therefore, the use of wedged prosthesis could prevent component loosening and enhance the success of cementless shoulders arthroplasty. © 2016 IEEE.
