“…In the studies by Morwood et al [15] and Szerlip et al [29] the outcome of the AM and the AF was compared. Denard and coworkers [9] did not differentiate between shoulders treated with AM or AF. Finally, Arthrex has developed a shortstem shoulder prosthesis called Apex™ (AP) and Romeo et al [21] reported on the outcome of 64 patients treated with…”

“…17 Bone resorption around the glenoid component in TSAs has been the main focus of study until recently, whereas humeral osteolysis has now gained more attention in the literature. 6,9,15,16,28,30,31 The cause of glenoid radiolucent lines (and perhaps subsequent loosening) is multifactorial. It can be related to glenoid or humeral component malposition, increased mechanical stress on the glenoid, increased friction between components, or the volume of polyethylene particles generated by the head-polyethylene articulation.…”

“…This observation is in keeping with observations in previous studies. 9,15 The tribology of the articulation in TSA may play a role in different osteolysis patterns observed around the proximal humerus with varied articulations. This is supported by a study by Raiss et al 28 : They analyzed 395 shoulder replacements with a mean follow-up period of 8.2 years and found that osteolysis only occurred in total shoulder replacements and not in hemiarthroplasties.…”

Background: In vitro wear studies demonstrate decreased polyethylene wear with a ceramic compared with a metal humeral head. In this in vivo study, we analyzed prospectively collected 5-year data, comparing the outcomes of 2 types of humeral implants. Methods: Sixty-two anatomic total shoulder arthroplasties (TSAs) (59 patients) were performed using the same glenoid component and 2 types of modular humeral implants (metal-head long-stem prosthesis in group A vs. ceramic-head stemless prosthesis in group B). Radiographic analysis for proximal humeral osteolysis and glenoid component radiolucent lines was performed at an average of 5.5 years. Functional outcomes were prospectively evaluated according to the visual analog scale score for pain; satisfaction level; American Shoulder and Elbow Surgeons score; active elevation; Shoulder Pain and Disability Index score; and Disabilities of the Arm, Shoulder and Hand score. Results: There were 39 TSAs in group A (mean age, 68.1 years) and 23 TSAs in group B (mean age, 67 years). Clinical improvement was similar for both groups. Some proximal humeral osteolysis occurred in 56% of all TSAs. Group A showed increased osteolysis compared with group B (72% vs. 30%, P ¼ .005). Glenoid radiolucent lines were far more frequent in group A, and group A showed a direct relationship between the extent of humeral osteolysis and the severity of glenoid radiolucent lines (P < .001). Conclusion: The stemless ceramic-head replacements showed fewer glenoid radiolucent lines and less humeral osteolysis than the long-stem metal-head replacements. In the group with metal-head replacements, correlation was shown between glenoid radiolucent lines and humeral osteolysis.

Humeral short stem varus–valgus alignment affects bone stress

The use of uncemented humeral stems in total shoulder arthroplasty (TSA) is associated with stress shielding. Shorter length stems have shown to decrease stress shielding; however, the effect of stem varus-valgus alignment is currently not known. The purpose of this study was to quantify the effect of short stem distal humeral endosteal contact due to varus-valgus angulation on bone stresses after TSA. Three-dimensional models of eight male cadaveric humeri were constructed from computed tomography data. Bone models were reconstructed with a short stem humeral component implant in three positions (standard, varus, and valgus).Modeling was performed at 45°and 75°of abduction and the resulting differentials in bone stress compared to the intact state and the expected time-zero bone response were determined. In cortical and trabecular bone, the standard position (STD) altered bone stress less than the valgus (VAL) and varus (VAR) positions relative to the intact state. For both cortical (p = 0.033) and trabecular (p = 0.012) bone, the VAL position produced a larger volume of bone with resorbing potential compared to the STD position.
