The authors describe a step-by-step technique for reverse total shoulder arthroplasty using arthrotomy via the enlarged transacromial superior approach. This technique seems ideal for reinsertion of the tuberosities and to ensure adequate postoperative tensional balance of the infraspinatus and the subscapularis, which is critical for the rotator cuffs to function properly and to achieve optima...

Background: To facilitate shoulder reduction and shorten time from shoulder dislocation to reduction, we started in 2014 a protocol for ultrasound-guided interscalene block (UGIB) in pure shoulder dislocation as well as dislocation with greater tuberosity fracture and dislocated shoulder arthroplasty. Methods: Within 30 month, patients with shoulder dislocation, dislocation-fracture or dislocat...

BACKGROUND Treatment of complex three and four-part proximal humeral fractures with hemiarthroplasty in elderly patients has yielded mixed clinical results. Reverse shoulder arthroplasty has emerged as a treatment option for comminuted proximal humeral fractures for these patients. The purpose of the study was to perform a prospective evaluation of patient outcomes comparing hemiarthroplasty an...

Acute proximal humeral fractures in the elderly are generally treated non-operatively if alignment is acceptable and in stable fracture patterns. When operative treatment is indicated, surgical fixation is often difficult or impossible to obtain. Hemiarthroplasty has long been the standard of care. However, with its reliance on tuberosity healing, functional outcomes and patient satisfaction ar...

Background The first articular metal prosthesis was implanted in the shoulder more than 120 years ago. The aim of this paper is to report shoulder arthroplasty evolution during this time thru the literature of the twentieth century. Methods A literature review was performed selecting the founding papers about shoulder arthroplasty. Results After being almost forgotten during the first part ...

BACKGROUND Examine 90-day postoperative mortality and its predictors following shoulder arthroplasty METHODS We identified vital status of all adults who underwent primary shoulder arthroplasty (Total shoulder arthroplasty (TSA) or humeral head replacement (HHR)) at the Mayo Clinic from 1976-2008, using the prospectively collected information from Total Joint Registry. We used univariate logi...

BACKGROUND The 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. METHODS We systematica...

HYPOTHESIS Distal peripheral neuropathy (DPN) is an under-reported complication after anatomic total shoulder arthroplasty (TSA), reverse shoulder arthroplasty (RSA), and arthroscopic rotator cuff repair (RCR). METHODS We conducted a retrospective review of patients undergoing shoulder arthroplasty or arthroscopic RCR by 4 shoulder surgeons during a 2-year period. The primary outcome measure ...

Fractures around the acromion are a known complication of reverse total shoulder arthroplasty. The literature provides limited data on the risk factors associated with this complication as well as the ultimate outcomes after nonoperative treatment. The goal of this study was to report clinical outcomes in patients with acromial fractures after nonoperatively treated reverse total shoulder arthr...
