Many commercial cemented glenoid components claim superior fixation designs and increased survivability.
The results of the cyclic load to failure tests show that the stability of the bone-implant constructs is correlated with the fixation design.
A 2-peg fixation design was analyzed for both an all-plastic and a metal-backed construction.
The results were compared with those of mandibles that had an angle fracture stabilized with different fixation designs under the same loadings.
It will help the researchers and the clinicians alike for the better treatment of patients and future development of new fixation designs.
We hypothesize that cement and bone stresses potentially leading to fixation failure are related not only to glenohumeral conformity, fixation design or eccentric loading, but also to bone volume fraction, cortical thickness and degree of anisotropy in the glenoid.
These results emphasize the need for accurate preoperative templating and for developing alignment guides or surgical navigation tools for shoulder arthroplasty and may be used to improve implant fixation designs.
However, keeping abreast of the large number of information available on these procedures, especially on implant fixation, designs, different tribological pairings, and the long‐term results can be challenging at times.
This paper presents the state of art review on finite element modelling application in the four areas of bone biomechanics, i.e., analysis of stress and strain, determination of mechanical properties, fracture fixation design (implants), and fracture load prediction.
