Guidelines for the selection of optimal glenoid augment size for moderate to severe glenohumeral osteoarthritis

Augmented glenoid component designs for type B2 erosions: a computational comparison by volume of bone removal and quality of remaining bone

“…15 Joint medialization was not explored in this study; instead, we focused on implant placement and underlying bone support, but it is also important to understand that implant medialization may result in peg perforation, compromising fixation. Also, additional bone removal is required to facilitate the fixation devices, which further compromises underlying bone support.…”

Templating in shoulder arthroplasty – A comparison of 2D CT to 3D CT planning software: A systematic review

“…20 Similarly, despite evidence suggesting computer-assistance and PSI improves alignment in total knee arthroplasty (TKA), systematic reviews revealed that neither PSI or computer-assisted TKA demonstrated cost-effectiveness or improved surgical efficiency. [21][22][23] Sassoon et al 22 highlighted, there was no evidence to support the improvement of pain, activity, function, or ROM when knee PSI was compared with conventional instrumentation. Burnett et al 23 suggest that while navigated TKA improves coronal alignment there was limited evidence to suggest improvements in any other variable and was associated with its own unique complications.…”

Analogous to the other technological advancements in different orthopedic subspecialties, 3D CT planning in shoulder arthroplasty may demonstrate small radiographic differences which may not prove to be clinically useful.…”

The arthritic glenoid: anatomy and arthroplasty designs

“…Recent clinical [19•, 20, 21], experimental [22][23][24][25][26], and computational [27][28][29][30][31] studies addressing asymmetric posterior glenoid erosion have focused on eccentric reaming and/or retroversion correction. It has been suggested that retroversion correction greater than 15°cannot be achieved with eccentric reaming alone [26,32].…”

“…When correcting version using eccentric reaming, bone grafting, or augmented glenoid components, it is important to recognize the degree of component medialization required for full backside contact of the glenoid component. In order to accommodate the design of some augmented glenoid components, glenoid vault peg perforation may occur [29,30]. Perforation may also occur when using standard components with eccentric reaming in patients with large degrees of acquired retroversion and may be one contributing factor to the reported maximum version correction.…”
