Abstract Background Compared with anatomic total shoulder arthroplasty (aTSA), reverse total shoulder arthroplasty (RTSA) is associated with lower preoperative and postoperative outcome scores and range of motion. It is unknown whether patients' preoperative expectations of surgery are lower in RTSA compared with aTSA. The purpose of this study was to assess preoperative patient expectations and postoperative outcomes in aTSA and RTSA. Methods A consecutive series of patients undergoing primary aTSA for diagnosis of osteoarthritis or primary RTSA for diagnosis of rotator cuff tear arthropathy were studied prospectively. Expectations were evaluated using the validated Hospital for Special Surgery's Shoulder Surgery Expectations Survey. Baseline demographics, comorbidities, and social factors were collected. Baseline and 2 years postoperative American Shoulder and Elbow Surgeons (ASES) score, visual analog scale pain, Single Assessment Number Evaluation (SANE), and patient satisfaction were obtained. Results There were 128 patients (64 aTSA and 64 RTSA). There was no significant difference in total preoperative expectations score between groups. On multivariate linear regression analysis, aTSA (p = 0.024) and younger age (p = 0.018) were associated with higher expectations for improved ability to exercise. Changes in preoperative to postoperative ASES (p = 0.004) and SANE (p = 0.001) scores were higher in the aTSA group. Total preoperative expectations score was not correlated with postoperative functional outcomes or satisfaction in either group. In the aTSA group, expectations for participation in exercise were positively correlated with changes in preoperative to postoperative ASES score (p = 0.01) and SANE score (p = 0.01). Conclusion Though patients undergoing primary aTSA demonstrated greater improvement in functional outcome than those undergoing primary RTSA, both groups reported similar aggregate preoperative expectations. Those undergoing aTSA had higher expectations for return to exercise which was positively correlated with postoperative functional outcomes. Level of Evidence Level II, prospective cohort study.

The Impact

Background Lateralization of the glenoid implant improves functional outcomes in Reverse Shoulder Arthroplasty. Lateralization does not appear to impact the Deltoid’s Moment Arm. Therefore, the stabilizing effect described in the literature would not be the result of an increase this moment arm. A static biomechanical model, derived from Magnetic Resonance Imaging, can be used to assess the coaptation effect of the Middle Deltoid. The objective of this study was to analyze the impact of increasing amounts of glenoid lateralization on the moment arm but also on its coaptation effect. Methods Eight patients (72.6 ± 6.5 years) operated for Reverse Shoulder Arthroplasty were included in the study. Three-dimensional models of each shoulder were created based on imaging taken at 6 months postoperative. A least square sphere representing the prosthetic implant was added to each 3D models. A static biomechanical model was then applied to different planar portions of the Middle Deltoid (from 3D models), first without lateralization and then with simulated lateralization of 6, 9 and 12mm. This static model enables to compute a Coaptation/Elevation Ratio and to measure the Deltoid’s Moment Arm. The inter- and intra-rater agreement of the 3D models was evaluated. Results One patient was excluded due to motion during imaging. The inter- and intra-rater agreement was over 0.99. The ratio increased starting at 6 mm of lateralization (p<0.05), compared to the initial position. The moment arm was not affected by lateralization (p<0.05), except in two slices starting at 9 mm (S1 p<0.05 and S2 p<0.05). Conclusion Our hypothesis that the Middle Deltoid’s coaptation role would be greater with glenosphere lateralization was confirmed. This trend was not found in the moment arm, which showed little sensitivity to lateralization. The stabilizing effect therefore appears to stem from the coaptation role of the Middle Deltoid.

Background Scapular spine insufficiency fractures following reverse shoulder arthroplasty are poorly understood. There exists limited literature regarding the role of reverse shoulder arthroplasty lateralization on scapular spine strains and fractures. The purpose of this cadaveric biomechanical simulator study was to evaluate the role of glenoid lateralization on scapular spine strain. Methods Eight cadaveric shoulders were tested using an in-vitro simulator. A custom modular reverse shoulder arthroplasty was implanted that allowed for in-situ glenoid lateralization adjustment. Scapular spine strain was measured by strain gauges placed in clinically relevant Levy zones along the scapular spine. All specimens were tested in loaded forward elevation and abduction. Results Glenoid lateralization from 0 to 5 mm caused negligible changes in scapular spine strains. Lateralization from 5 to 10 mm, however, caused significant increases in strain at 0° forward elevation in all strain gauges (p < 0.026). Strains measured in Levy zone 2 were significantly higher than all other locations (p < 0.039). Additionally, forward elevation resulted in significantly higher strain values than abduction (p = 0.001). Conclusions Glenoid lateralization is an important parameter in reverse shoulder arthroplasty; however, our results demonstrate higher degrees of lateralization may place higher strains on the scapular spine. An understanding of reverse shoulder arthroplasty lateralization and scapular spine strains is important to optimize parameters and to mitigate negative effects.
