Medical - Medical: Instruments / shoulder surgery (rotator
English term or phrase: IB-RTSA (inverted bearing reverse total shoulder arthroplasty)
This is a technical medical document dealing with the affinis inverse system (reverse total shoulder arthroplasty).

Context:
The common reverse total shoulder arthroplasty (RTSA) has “soft” polyethylene (UHMWPE) inlays and “hard” cobalt– chromium (CoCr) glenospheres.
In inverted bearing reverse total shoulder arthroplasty "(IB-RTSA)", such as the Affinis Inverse (Fig. 1), the humeral inlays are made from metal or ceramic and the glenospheres from PE.
The notching phenomenon of a “hard” and wear-resistant humeral inlay with the scapula results in a different characteristic.
Excessive abrasive wear on the scapular bone, respectively, PE-induced osteolysis is eliminated.
With the humeral inlay made from metal or ceramic, the characteristic remains with a simple mechanical notching"

I have no problem with the RTSA as it is translated "Prothèse totale de l'épaule inversée" (PTEI)

But I do not know how to translate the "IB"part. Matériaux inversés? which would lead to the acronym MI-PTEI but althouth PTEI often appears on google, MI alone or in association with PTEI as a double jointed acronym does not appear.

So actually my question only really relates to IB (inverted bearing) and the correct acronym for this. IT could also be translated "support inversé"but there again the acronym SI is missing...

Notes to answerer
Asker: Oui effectivement c'est bien le sens mais je ne trouve toujours pas l'acronyme "BI PTEI" et de plus le terme biomécanique ne convient pas toujours dans ce contexte pour traduire le terme "bearing", comme en témoigne mon autre question sur "bearing diameter". Je crois que le terme doit signifier un objet (puisqu'il a un diamètre) plutôt qu'un fonctionnement. Et veuillez m'excuser d'être si difficile, mais je suis à la recherche du terme exact, réutilisable dans pour l'ensemble des références dans ce texte.
