“…Taunton and co-authors reported on 83 ATSA with a metalbacked, bone-ingrowth glenoid component and found a 40 % rate of glenoid component loosening and 25 % rate of polyethylene wear with metal wear of the glenoid component [22]. Boileau, et al reported a 20 % loosening rate of metal-backed glenoid components compared to 0 % in all polyethylene glenoids in a prospective study of 40 patients undergoing ATSA [23]. Improvements in modern implant design may ameliorate these issues, as a recent study that included twelve primary platform ATSA with metal-backed glenoid components revised to RTSA did not report any metal-backed glenoid revisions [10•].…”

A platform system for shoulder arthroplasty can include a convertible modular humeral stem and/or a metal-backed glenoid component to facilitate straightforward conversion from either a hemiarthroplasty or anatomic total shoulder arthroplasty to a subsequent anatomic total shoulder arthroplasty, or more frequently, reverse total shoulder arthroplasty without any revision to the stem and/or glenoid baseplate. Recent studies have demonstrated a decreased rate of intraoperative humeral fracture, complications, and blood loss when a platform system is used and the humeral stem is not exchanged during revision arthroplasty. Future studies with larger patient cohorts are necessary to truly evaluate the potential value and limitations of this technology.

“…Studies differ widely when considering the rate of glenoid radiolucent lines, probably because many different circumstances can produce them, such as component mismatch, cemented or metal-backed, pegged or keeled components, position of the scapula on the radiograph, and cement techniques [2,8,10,16,19,22]. However, a direct correlation of radiolucent lines with component loosening, as well as the significance of their size and location, is still unproven [10].…”

“…The presence of radiolucent lines around arthroplasty components has been attributed to several different factors, including poor cementing technique, component design, surgical technique, bone quality and component stability [2,8,10,11,16,22]. While the significance and clinical correlation of size and location of radiolucent lines is still unknown, the progression of a radiolucent line over time has been commonly associated with component loosening [8].…”

“…While the significance and clinical correlation of size and location of radiolucent lines is still unknown, the progression of a radiolucent line over time has been commonly associated with component loosening [8]. The rate of radiolucent lines observed is extremely variable from one study to another, making the comparison of related factors more difficult [2,4,8,16,20,22].…”

We report on the concordance and reproducibility of the evaluation of radiolucent lines in the humeral component of shoulder arthroplasty. Thirty-two shoulder prostheses were assessed independently, on two occasions, by five observers. The level of inter-and intra-observer agreement was calculated using the kappa statistic. Intraobserver agreement: the overall kappa values ranged from 0 to 0.6, meaning poor, fair and moderate agreement levels. Interobserver agreement: when the anteroposterior (AP) views were analysed, the values obtained for the bone-cement interface ranged from 0.290 to 0.539, meaning a poor-tomoderate agreement. For the cement-implant interface, the values ranged from 0.064 to 0.684, meaning a poor-to-good agreement. When radiolucent lines of the humeral component were analysed, inter-observer agreement proved to be as low as that obtained when total hip or knee components were analysed. Intra-observer agreement showed better results.

“…As for the knee, metal backing has been proposed to improve the fixation of the glenoid component. Although preliminary results were not satisfactory (Boileau et al, 2002), new design is still considered as an alternative to the all-polyethylene solution (Fucentese et al, 2010). Numerical tools have been used widely to perform parametric analyses in total shoulder arthroplasty (Friedman et al, 1992;Lacroix and Prendergast, 1997;Lacroix et al, 2000;Mansat et al, 2007;Murphy et al, 2001;Orr et al, 1988;Stone et al, 1999).…”

Background: Articular surfaces reconstruction is essential in total shoulder arthroplasty. Because of the limited glenoid bone support, thin glenoid component could improve anatomical reconstruction, but adverse mechanical effects might appear. Methods: With a numerical musculoskeletal shoulder model, we analysed and compared three values of thickness of a typical all-polyethylene glenoid component: 2, 4 (reference) and 6 mm. A loaded movement of abduction in the scapular plane was simulated. We evaluated the humeral head translation, the muscle moment arms, the joint force, the articular contact pattern, and the polyethylene and cement stress. Findings Decreasing polyethylene thickness from 6 to 2 mm slightly increased humeral head translation and muscle moment arms. This induced a small decreased of the joint reaction force, but important increase of stress within the polyethylene and the cement mantel. Interpretation The reference thickness of 4 mm seems a good compromise to avoid stress concentration and joint stuffing.
