AI Technical Summary

Technical Problem

Recurrent shoulder instability after reverse total shoulder arthroplasty (rTSA) is a challenging clinical issue, particularly during revision procedures, as current methods like increasing humeral component thickness or glenohumeral cerclage are not always effective, and drilling holes in the glenoid bone for suture placement is technically demanding and difficult to position accurately.

Method used

Glenoid implants with integrated ligature retaining features, such as holes and grooves, allow for multiple points of suture attachment, enhancing stability through glenohumeral cerclage by providing secure anchoring options on the baseplate and glenosphere components, using materials like porous metal with smooth surfaces to prevent abrasion.

Benefits of technology

The glenoid implants with ligature retaining features enhance shoulder joint stability by allowing secure suture placement at multiple locations, reducing the risk of dislocation and improving the effectiveness of cerclage procedures.

Abstract

Disclosed is a glenoid baseplate implant that is configured to include a transverse body having a first side configured to engage scapula bone of a patient, a second side configured to face away from the first side; and one or more ligature retaining features provided on the transverse body that is useful for enabling a glenohumeral cerclage. Also disclosed is a glenosphere implant that includes one or more ligature retaining features.
