Background:.
Reverse shoulder arthroplasty (RSA) was released into the United States market in 2004 for the indication of Rotator Cuff Tear Arthropathy. Since that time the indications have widened and now include
BACKGROUND:. Few studies have evaluated at a medium-term follow-up the use of semiconstrained reverse shoulder arthroplasty (RSA) for primary glenohumeral osteoarthritis,

Background:. The purpose of this study was to compare the biomechanical effects of the trapezius transfer and the latissimus dorsi transfer in a cadaveric model of a
INTRODUCTION. Shoulder joint prostheses have become the most commonly replaced after knee and hip artificial implants. Reverse shoulder arthroplasty (RSA) is the treatment option for patients with severe osteoarthritis, rotator cuff arthropathy or a
Introduction. Total shoulder arthroplasty is the fastest growing joint replacement in recent years, with projected compound annual growth rates of 10% for 2016 through 2021 – higher than those of both the hip and knee combined. Reverse total shoulder arthroplasty (RTSA) has gained particular interest as a solution for patients with irreparable
Massive tears of the supraspinatus of the rotator cuff lead to painful loss of movement. The literature supports repair of these tears for young healthy individuals, however they present a surgical challenge with historically poor results from both athroscopic and standard open techniques. Prof Bunker has developed a surgical technique for
Introduction:. Reverse shoulder arthroplasty (RSA) is a reasonable treatment modality in patients with Cuff Tear Arthropaty and massive irreparable cuff tears. RSA has been shown to increase patient function and decrease pain. The aim of this study is to evaluate the clinical and radiographic results of a 44 polyethylene glenosphere. Methods:. Since 2008 we treated 88 patients with cuff tear arthropaty and irreparable massive cuff tear, using an RSA. We selected 80 patients with minimum FU of 24 months in which we used an implant with polyethylene glenosphere and metal humeral insert. Size of the glenosphere used was 44. All patients were assessed with the Constant score and with VAS. The shoulder ROM was measured preoperatively and postoperatively. Results:. Average age of the patients was 71 years old. Average duration of FU was 34 months. All measures improved significantly (p < 0.0001). The mean Constant improved from 15.6 to 60.2. VAS improved from 6 to 2,5. Forward flexion increased from 40 ° to 126,4 °, abduction from 41 ° to 103 °, external rotation from 15.1 to 17.3 and internal rotation increased by two level. We report 22 cases of scapular notching without clinical influence and without implant mobilization. Conclusion:. This is the first report of the use of a polyethylene glenosphere. Data from this study suggest that RSA with a polyethylene glenosphere may be a viable treatment for patients with glenohumeral arthritis and a

Introduction:. 90 cases of reversed prosthesis have been evaluated and the aim of the retrospective multicenter study was to correlate the functional and radiological results depending on the type of implant. Material & Methods:. 90 patients have been operated (67 eccentric omarthrosis, 5 centered omarthrosis, 7
Background.
Purpose. Management of massive, degenerative, and irreparable rotator cuff tears is challenging. Excessive re-tear rates and poor clinical outcome after standard repair have led to alternative methods of treatment. Tendon transfers and shoulder arthroplasty have had mixed results; both are invasive procedures with high potential morbidity. We began performing rotator cuff augmentation and replacement using GraftJacket allograft acellular human dermal matrix as a biologic minimally invasive alternative in this difficult population almost 6 years ago. This article highlights our preferred arthroscopic technique and early results. Method. From January 2004 to June 2007, 45 patients (36 men, 9 women) with
Background:. Currently, there are a variety of different reverse shoulder implant designs but few anatomic studies to support the optimal selection of prosthetic size. This study analyzed the glenohumeral relationships of patients who underwent reverse shoulder arthroplasty (RSA). Methods:. Ninety-two shoulders of patients undergoing primary RSA for a
Introduction:. Reverse total shoulder arthroplasty (RTSA) has become instrumental in relieving pain and returning function to patients with end-stage rotator cuff disease. A distalized and medialized center of rotation in addition to a semi-constrained implant design allows the deltoid to substitute for the non-functioning rotator cuff. The purpose of this study was to examine the relationship between specific deltoid and rotator cuff muscle parameters and functional outcomes following RTSA. Methods:. Patients undergoing RTSA by a single surgeon were enrolled in a prospective, IRB approved RTSA outcomes registry. Inclusion criteria were diagnosis of cuff tear arthropathy or

Rotator cuff tears are the most common cause of shoulder disability, affecting 10% of the population under 60 and 40% of those aged 70 and above.
