“…Risk of complication was nearly three times higher in revision arthroplasty cases. The magnitude of improvements in functional scores and active elevation and the complication rate were similar to those reported in other series of RTSA for rotator cuff arthropathy [6,12,20,54,60]. These data demonstrate that with proper use in rotator cuff deficient shoulders, patients can obtain excellent clinical function following implantation of a RTSA.…”

“…The indications for RTSA have expanded over the last few years and include CTA [15,18,26,50,57,61], inflammatory arthropathy with massive rotator cuff tear [26,45], proximal humeral nonunion or malunion [6,34,57], acute fractures [34,57,58], fixed glenohumeral dislocation [57], posttraumatic arthritis [26,57], tumor [4,13,35,57], revision arthroplasty [6,27,33,57], and chronic pseudoparalysis without arthritis [41,57,60,61]. We will limit our discussion to problems dealing with the rotator cuff.…”

“…The RTSA was originally designed to treat a massive irreparable rotator cuff with superior migration of the humeral head combined with glenohumeral arthritis (cuff tear arthropathy [CTA]) [5,15,18,21,40]. The indications have expanded however, and currently it is being used for multiple diagnoses including fracture sequelae [6,31,32,34,58], revision arthroplasty [6,27,33,57], instability [57], and tumors [4,13,35,57]. As a result of its success with these problems, its indications are gradually increasing, and many are unsure about its role in the treatment of rotator cuff disease.…”

Background Reverse total shoulder arthroplasty (RTSA) was introduced to treat rotator cuff tear arthropathy but is now used to treat a variety of problems. Although its use has expanded substantially since the FDA's approval in 2004, the appropriateness in patients with rotator cuff disease is unclear. Questions/purposes We review the use of RTSA in patients with rotator cuff disease to (1) describe classification of rotator cuff tear reparability and the concept of a balanced shoulder; (2) explore the theory behind RTSA design relative to rotator cuff arthropathy; (3) discuss the indications and contraindications for RTSA; and (4) review published outcomes of RTSA for rotator cuff arthropathy.Methods We performed a selective review of the literature on the use of RTSA in the treatment of rotator cuff disease.Results Modern RTSA designs restore deltoid tension and a functional fulcrum to the rotator cuff deficient shoulder, which allows recovery of active shoulder elevation and effectively restores function in short-and mediumterm followup studies. Conclusions In short-term followup the RTSA relieves symptoms and restores function for patients with cuff tear arthropathy and irreparable rotator cuff tears with pseudoparalysis (preserved deltoid contraction but loss of active elevation). Severely impaired deltoid function, an isolated supraspinatus tear, and the presence of full active shoulder elevation with a massive rotator cuff tear and arthritis are contraindications to RTSA. Clinical Relevance For properly selected patients who have symptomatic and disabling rotator cuff deficiency, RTSA can result in life-changing improvements in pain, motion, function, and patient satisfaction. Level of Evidence Level V therapeutic study. See Guidelines for Authors for a complete description of levels of evidence.

“…The lack of micromotion in the reverse shoulder implants we observed may be due to less aggressive biomechanical loading or more robust fixation than has been reported for conventional total shoulder arthroplasty (Anglin et al, 2000a, Collins et al, 1992. On the other hand, our in vitro results may confirm clinical studies that rarely observed glenoid loosening in the initial postoperative period (Boileau et al, 2006, Werner et al, 2005. This would suggest that in vivo loosening of the reverse glenoid component may not be due to poor primary stability but could be attributed to other factors such as poor secondary stability due to inadequate bone quality, insufficient screw purchase or component malpositioning (Guery et al, 2006, Werner et al, 2005.…”

“…Reverse total shoulder arthroplasty has been shown to improve function and pain in the treatment of massive rotator cuff tear and cuff tear arthropathy, rheumatoid arthritis, fractures, or revision arthroplasty (Boileau et al, 2006, Gerber et al, 2009, Guery et al, 2006, Sirveaux et al, 2004, Werner et al, 2005. Nevertheless, the rate of problems remains high, in part because of glenoid component loosening (Gerber et al, 2009, Mole andFavard, 2007).…”

BACKGROUND: Baseplate micromotion of the reverse shoulder glenoid component can lead to implant loosening. We hypothesized that a remotely positioned displacement gage measures elastic deformation of the system rather than actual micromotion at the implant/bone interface. METHODS: Reverse glenoid components were implanted into polyurethane blocks of 3 different densities. A 700 N compressive load was maintained and a vertical 700 N shear load was applied for 1000 cycles. In addition to the typical gage measurement, a digital image analysis of micromotion at the implant/block interface using high resolution cameras was performed. The measurements were validated on human specimens. A finite element model was implemented to study the isolated effect of block deformation on baseplate displacements. FINDINGS: With the gage, typically reported micromotions were measured. Two orders of magnitude lower micromotions were detected using interface image-based analysis. The finite element simulation showed that elastic deformation alone can cause micromotion magnitudes as measured with displacement gages. Polyurethane blocks of 20 and 15 lbs per cubic foot density best reproduced micromotions as measured on human specimens. INTERPRETATION: We found considerably less relative micromotion at the implant/bone interface than previously assumed. Gage measurements quantify elastic deformation and not true interface micromotion. High resolution digital imaging at the implant/bone interface is strongly recommended for an accurate assessment of reverse glenoid component micromotion.
