“…Compared with stemmed humeral prostheses, there are lower rates of bleeding and fracture because a humeral osteotomy is not performed. 61,62 Additionally, bone stock is preserved for future revisions. Studies have shown improved functional outcomes with resurfacing.…”

The number of shoulder arthroplasties performed in the United States has more than doubled in the last decade. Additionally, there has been a trend toward use of reverse total shoulder arthroplasty and minimally invasive surgical techniques, such as resurfacing humeral head arthroplasty. Thus radiologists will more frequently encounter imaging of shoulder arthroplasty and these new designs. Successful postoperative radiologic evaluation of shoulder reconstructions requires an understanding of their fundamental hardware design, physiologic objective, preoperative imaging assessment, normal postoperative radiologic appearance, and findings and types of complication. This article discusses the designs of prostheses used around the shoulder joint, delineates indications and alternatives for each of the different types of hardware, reviews radiographic and cross-sectional preoperative imaging of shoulder arthroplasty, illustrates normal postoperative imaging findings and measurements, and provides examples of hardware complications.

“…The analysis was performed in order to obtain results about how the artificial design responds to different factors, such as load, type of material, and type of test. The dimensions of the global humeral head implant are assessed based upon the observed variability in humeral head sizes in the normal shoulder [17][18]. The stress and surface deformation analyses were done on the artificial HH using three different biomaterials: Co-Cr alloy, Ni-Ti alloy, and Al-foam (their properties were described previously in Table 1).…”

Assessment of dimensional and geometrical data on the humeral head replacement (HHR) objects is essential for solving the relevant designing problems in the physics of reverse engineering (RE). In this work, 2D-assessment for human humerus was performed using the computed tomography (CT) technique within the RE plan, after which the 2D images of humeral objects were converted into 3D images. The conversion was successful and indicated a clear difference in the 2D and 3D estimates of sizes and geometry of the humerus. The authors have analyzed and confirmed experimentally the statistical information on the relevant anatomical objects. The results of finite-element simulation of the compressive stresses affecting the geometry of 3D surface mapping were analyzed using SolidWorks software. For developing the biomechanical design of an HHR object suitable biomaterials were selected, and different metal-based biomaterials are discussed as applied at various loads. New methodology is presented for the size estimation of humeral head -both anatomical and artificial -in 3D-shape. A detailed interpretation is given for the results of CT D-measurements.

“…Several national registry studies compared patient-reported outcomes between RHA and SHA but no significant differences were observed [38][39][40]. Moreover, a published review comprehensively discussed their indications, clinical assessment, patients' satisfaction and postoperative complications but was restricted to descriptive analysis [41]. To the best of our knowledge, there was no meta-analysis that provided more reliable evidence on this issue.…”

Resurfacing hemiarthroplasty versus stemmed hemiarthroplasty for glenohumeral osteoarthritis: a meta-analysis

et al. 2020

Background: Though total shoulder arthroplasty (TSA) has been an acknowledged treatment option for glenohumeral osteoarthritis, resurfacing hemiarthroplasty (RHA) and stemmed hemiarthroplasty (SHA) may be preferred in some circumstances by surgeons, especially for treating young or active patients. However, decision-making between the RHA and SHA is controversial. Therefore, we conducted a meta-analysis to systematically compare two surgical procedures in terms of postoperative functional outcomes, range of motion (ROM), pain relief, complication rates, risk of revision. Methods: The PubMed, Embase, Web of Science and Cochrane Library were searched from inception to January 1, 2020, for all articles that compared the clinical effectiveness and safety of RHA with SHA. All eligible studies were selected based on certain screening criteria. Two investigators independently conducted the quality assessment and extracted the data. Fixed-effect and random-effect models were used for pooled results according to the degree of heterogeneity. All statistical analyses were performed by employing Stata software 14.0. Results: A total of six comparative studies involving 2568 shoulders (1356 RHA and 1212 SHA) were included in the final analysis. Patients were followed up for at least 1 year in each study. Pooled results showed that RHA was associated with a better visual analog scale (SMD 0.61, p = 0.001) but higher revision rates (OR 1.50, p = 0.016) when compared to SHA. There were no significant differences in functional outcomes, such as Constant-Murley score (SMD 0.06, P = 0.878), American Shoulder and Elbow Surgeons score (SMD 0.05, P = 0.880), Western Ontario Osteoarthritis of the Shoulder index (SMD 0.43, p = 0.258) and quick-Disabilities of the Arm, Shoulder and Hand score (SMD 0.06, p = 0.669). In addition, no differences were observed in forward flexion (SMD 0.16, p = 0.622), external rotation (SMD-0.17, P = 0.741) and overall complication rates (OR 1.42, p = 0.198).
