d The most common complications after reverse shoulder arthroplasty in order of decreasing frequency included instability, periprosthetic fracture, infection, component loosening, neural injury, acromial and/or scapular spine fracture, hematoma, deltoid injury, rotator cuff tear, and venous thromboembolism (VTE).d The most common complications after anatomic total shoulder arthroplasty (TSA) in order of decreasing frequency were component loosening, glenoid wear, instability, rotator cuff tear, periprosthetic fracture, neural injury, infection, hematoma, deltoid injury, and VTE.d Glenoid component wear and loosening remain a common cause of failure after anatomic TSA, despite advances in surgical technique and implant design.d Diagnostic confirmation of infection after shoulder arthroplasty remains a challenge. In the setting of a painful and stiff shoulder after arthroplasty, the surgeon should have a heightened suspicion for infection. Inflammatory markers may be normal, radiographs may be inconclusive, and prosthetic joint aspiration may be negative for a causative organism.Disclosure: The authors indicated that no external funding was received for any aspect of this work.

“…However, there is not yet any test available to objectively determine bone quality pre- or intraoperatively [29]. Churchill et al [18] described the use of a “thumb test” in which bone quality is intraoperatively assessed by compressing the surface of the neck cut with the thumb. Overall, the presently reviewed studies reported only a few isolated cases of loosening of the stemless component.…”

“…In this review article, the terms “canal-sparing” respectively “stemless” refer to implant designs with metaphyseal fixation using a standard humeral neck cut, and excluding humeral head resurfacing techniques. Canal-sparing respectively stemless shoulder arthroplasty must not be confused with resurfacing techniques that aim to restore joint congruency by preserving the majority of the humeral head bone stock and implantation of a metallic cap over the remaining humeral head bone stock [3, 12–18]. …”

BackgroundThe latest generation of shoulder arthroplasty includes canal-sparing respectively stemless designs that have been developed to allow restoration of the glenohumeral center of rotation independently from the shaft, and to avoid stem-related complications. The stemless prosthesis design has also recently been introduced for use in reverse arthroplasty systems.MethodsWe systematically reviewed the literature for studies of currently available canal-sparing respectively stemless shoulder arthroplasty systems. From the identified series, we recorded the indications, outcome measures, and humeral-sided complications.ResultsWe identified 11 studies of canal-sparing respectively stemless anatomic shoulder arthroplasty implants, published between 2010 and 2016. These studies included 929 cases, and had a mean follow-up of 26 months (range, 6 to 72 months). The rates of humeral component-related complications ranged between 0 and 7.9 %. The studies reported only a few isolated cases of complications of the humeral component. Some arthroplasty systems are associated with radiological changes, but without any clinical relevance.ConclusionsAll of the published studies of canal-sparing respectively stemless shoulder arthroplasty reported promising clinical and radiological outcomes in short to midterm follow-up. Long-term studies are needed to demonstrate the long-term value of these kind of implants.

“…Via this model, a central wire was placed in the humerus and the metaphysis was prepared using a drill and an impaction instrument (Figs. 5,b,and 6,b). Then, the anchor was positioned in the metaphysis, and the humeral head was placed on top of the anchor (Fig.…”
