“…Types B2 and C present the most severe cases of GBL. A B2-type glenoid is characterized by glenoid biconcavity consisting of both a paleo glenoid (native glenoid) as well as a neo glenoid (new glenoid) and often have varying degrees of posterior humeral head subluxation, while a C-type glenoid is characterized by retroversion greater than 25° ( 1 - 3 , 7 , 11 , 12 , 17 , 19 - 21 ).…”

“…It considers E0 involving superior humeral head migration with no glenoid erosion, E1 which involves concentric central erosion of the glenoid, E2 which involves superior erosion of the glenoid, E3 which involves superior erosion of the glenoid that extends inferiorly, and E4 which involves inferior erosion of the glenoid. This classification system is especially helpful for planning how to compensate for superior wear and to avoid the error of placing the baseplate in a superiorly tilted position if not addressed appropriately ( 2 , 3 , 12 , 17 , 23 , 24 ).…”

Background and Objective Crucial to the success of any total or reverse shoulder arthroplasty (RSA) is the stability of the glenoid component fixation. Instability can lead to early implant failure and unsatisfactory results. Patients often present with varying forms of glenoid bone loss (GBL) in both the primary and revision settings, which can be a challenge for the treating surgeon. Severe cases of GBL can increase the risk of potential complications and diminish implant longevity. The use of the reverse total shoulder replacement has been particularly helpful when addressing significant glenoid bony defects. Various approaches have been proposed to deal with GBL, all of which require an individualized assessment of the specifics of the defect in order to provide maximal fixation and thereby optimize the longevity of the shoulder arthroplasty. This article aims to review the recent literature on GBL in shoulder arthroplasty to provide guidance when considering treatment based on the best available evidence. Methods PubMed, MEDLINE, EMBASE, AccessMedicine, ClinicalKey, DynaMed, and Micromedex were queried for publications utilizing the following keywords: “glenoid bone loss” AND “glenoid bone deficiency” AND “shoulder arthroplasty” AND “classification”. The search was restricted to research published between 2004 and 2023. There were no restrictions on study type or language. Key Content and Findings GBL should be critically evaluated prior to undertaking total shoulder arthroplasty (TSA). The treating surgeon should be aware of various methods of addressing bone defects. Conclusions The use of TSA is increasing to address various shoulder pathologies. Addressing glenoid bone defects is of critical importance to maximize the longevity and outcome of TSA.

BackgroundAseptic loosening is considered to be a rather uncommon complication in proximal humerus endoprosthetic replacement (PHER). However, patients with aseptic loosening often suffer severe bone loss, which poses a great challenge in following revision. Under this situation, a standard stemmed endoprosthesis is unavailable for revision limb salvage. Computer‐aided design and 3D‐printed personalized implants are an emerging solution for reconstructing complex bone defects.Case PresentationHere, we present a 67‐year‐old male who underwent PHER after tumor resection and developed aseptic loosening with severe periprosthetic osteolysis around the stem. Computer‐aided design and 3D‐printed personalized stem‐plate composite was used for the precision revision of this patient. During the follow‐up, encouraging results were observed, with good endoprosthetic stability and satisfactory limb function.ConclusionComputer‐aid design and 3D‐printed personalized stem‐plate composite used in the present case could help to achieve good endoprosthetic stability and satisfactory limb function. This 3D‐printed personalized stem‐plate composite seems to be an effective method for the precise revision of PHER in patients with severe periprosthetic osteolysis. In addition, it also provides a novel method for similar revision surgery of other joints or primary endoprosthetic replacement with severe bone defects.
