The Reverse Shoulder Prosthesis for Glenohumeral Arthritis Associated with Severe Rotator Cuff Deficiency<sbt aid="1022701">A Minimum Two-Year Follow-up Study of Sixty Patients</sbt>

Abstract

The data from this study suggest that arthroplasty with the Reverse Shoulder Prosthesis may be a viable treatment for patients with glenohumeral arthritis and a massive rotator cuff tear. However, future studies will be necessary to determine the longevity of the implant and whether it will provide continued improvement in function.

Reverse shoulder prosthesis in patients with rheumatoid arthritis: a systematic review

“…Of the 45 patients of this review for whom the subjective outcome of surgery was reported [42,44,46], 77 % considered their results as excellent or good. This rate is comparable to that obtained recorded in several studies in which the RSA was mostly implanted for massive cuff tears or CTA [10,13,31,51].…”

“…The mean prevalence of scapular notching was 35 %, which is similar to the percentages reported in several studies [13,31,33,34] in which the rate ranged from 43 to 51 %, and lower than the 68 % found by Boileau et al [9]. As in other studies [30,33], the notching did not appear to affect the clinical outcome.…”

“…In the series of 80 shoulders of Sirveaux et al [51], the mean Cs increased by 43 points and the flexion by 65°. In the cohort of Frankle et al [13], the mean total ASES score improved by 33.9 points, the VAS score for pain by 3.3 points, and the mean flexion and abduction by 50,1 and 59.6°, respectively. Wall et al [34], in a cohort of 103 shoulders followed for a mean of 39.9 months, found a mean improvement in Cs of 39.5 points.…”

“…Of the latter, 33 were excluded. In 19 reporting on patients who had undergone RSA or TSA, there were no rheumatoid patients with RSA [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25]; nine studies on patients who had had an RSA for various aetiologies included one or more rheumatoid patients, but no or insufficient information was provided on their outcomes [26][27][28][29][30][31][32][33][34]; three review articles on RSA in patients with various conditions gave very little information, contained in a short paragraph [35,36], or limited information [37], for the RA group; there were also two articles of general information on shoulder arthroplasty reporting no own case series [38,39]. Two additional studies reported enough pertinent and useful information on several [40] or many [41] RA patients undergoing RSA, but they were excluded because the mean follow-up was less than 36 months and the longest did not reach five years.…”

The use of an eccentric glenosphere compared with a concentric glenosphere in reverse total shoulder arthroplasty: two-year minimum follow-up results

“…However, a recent study has shown that this technique alone is not sufficient to avoid notching [13]. Frankle [18] has conceived a model of reverse prosthesis with an increased lateral offset of the glenosphere and/or baseplate. However, the lateralisation of the glenoid component that is achieved has the drawback of increasing the torque or shear force on the glenoid, and thus could potentially increase the risk of loosening of the component.…”
