THEORY: Models on pre-assessment learning effects confirmed that task demands stand out among the factors assessors can modify in an assessment to influence learning. However, little is known about which tasks in objective structured clinical examinations (OSCEs) improve students' cognitive and metacognitive processes. Research is needed to support OSCE designs that benefit students' metacognitive strategies when they are studying, reinforcing a hypothesis-driven approach. With that intent, hypothesis-driven physical examination (HDPE) assessments ask students to elicit and interpret findings of the physical exam to reach a diagnosis ("Examine this patient with a painful shoulder to reach a diagnosis")...

INTRODUCTION AND OBJECTIVE: Reverse total shoulder arthroplasty in rotator cuff arthropathy patients, improves anteversion and abduction, but not rotational, outcomes. The main aim of this study is to determine its repercussions on daily life activities in our patients. MATERIAL AND METHODS: Between 2009 and 2011 we implanted 210 shoulder arthroplasties, 126 of them were reverse total shoulder arthroplasty in a rotator cuff arthropathy context. About 88% were women, with a mean age at time of surgery of 81 years, 95% were retired...

BACKGROUND: Humeral component lateralization in reverse total shoulder arthroplasty (RTSA) may improve the biomechanical advantage of the rotator cuff, which could improve the torque generated by the rotator cuff and increase internal and external rotation of the shoulder. PURPOSE: The purpose of this in vitro biomechanical study was to evaluate the effect of humeral component lateralization (or lateral offset) on the torque of the anterior and posterior rotator cuff...

Anders L Ekelund
Even though reverse shoulder arthroplasty is a very successful procedure, painful complications occur. During the initial postoperative years, the most common reasons for pain are instability, postoperative fracture of the acromion or spine, and periprosthetic infection. Later, aseptic loosening, with humeral loosening being more frequent that glenoid loosening, can be a source of pain and reduction in function. A careful patient history, clinical examination, plain radiographs, computed tomography and blood tests give an explanation for the pain in most cases...

A 53-year-old woman presented with 10-year history of pain and limited range of motion in both shoulders. Radiographs of both shoulders showed severe shoulder osteoarthritis with glenoid bone defect. Very thin rotator cuff and superior migration of the humerus were also observed on computed tomography images. We performed bony increased-offset reverse total shoulder arthroplasty on her both shoulders. The patient had a good clinical outcome without any particular complication.

BACKGROUND: Reverse shoulder arthroplasty (RSA) requires lowering the humerus and medialisation of the centre of rotation. Several techniques based on standard X-rays are available in the literature. The aim of this study was to expose and validate a new technique for measuring these parameters. MATERIALS AND METHODS: Radiographic data of 20 patients were included. Three observers examined each X-rays three times to establish the inter- and intra-reproducibility of each technique (Jobin, Renaud and our method)...

REVIEW

This paper seeks to outline recent legal developments and requirements pertinent to obtaining informed consent. We argue that this is of particular relevance to patients considering a reverse total shoulder arthroplasty, due to the high complication rate associated with this procedure. By examining the cognitive processes involved in decision-making, and other clinician-related factors such as delivery of information, gender bias and conflict of interest, we explore some of the barriers that can undermine the processes of shared decision-making and obtaining genuine informed consent...

BACKGROUND: The purpose of this study was to investigate the results and complications during the learning curve of reverse total shoulder arthroplasty (RTSA) for rotator cuff deficiency. METHODS: We retrospectively reviewed the first 40 cases of RTSA performed by a single surgeon. The mean age of patients was 72.7 years (range, 63 to 81 years) and mean follow-up period was 26.7 months (range, 9 to 57 months). Clinical outcomes were evaluated using a visual analog scale (VAS) for pain, the University of California at Los Angeles (UCLA) shoulder score, American Shoulder and Elbow Surgeon (ASES) score, subjective shoulder value (SSV), and active range of motion (ROM)...

BACKGROUND: Reverse total shoulder arthroplasty has become a widely accepted surgical procedure in Japan since the time when the implants were approved for use in 2014. There is a doubt, however, as to whether the implants designed for Western people are suitable for Japanese people, particularly for females of relatively small stature. The purpose of this study was to investigate the glenoid dimension, with special focus on the length after glenoid reaming, in Japanese rotator cuff tear patients...

The management of irreparable rotator cuff tears is a difficult problem to deal with. The options include nonoperative route with anterior deltoid exercises, debridement with or without long head of biceps tenotomy, partial rotator cuff repair, tuberoplasty, muscle transfer, patch augmentation, biodegradable spacers, and reverse shoulder arthroplasty. None of these options are without their limitations. In recent years, arthroscopic superior capsular reconstruction has gained popularity as an alternative technique to address irreparable rotator cuff tears...

Reverse shoulder arthroplasty (RSA) in its modern design was first introduced over 25 years ago and approved by the American FDA over ten years ago. This type of prosthesis allows treatment of glenohumeral joint disease among patients with severe rotator cuff deficiency once thought to be inoperable. Modifications to the prosthesis design, along with improved surgical technique, led to better clinical outcomes and lower complication rates, which subsequently led to an increase in the usage of this implant device...

BACKGROUND: A previously validated finite element modeling approach was used to determine how changes in glenoid component version and polyethylene liner rotation within the humeral component affect the arm abduction angle at which impingement between the inferior glenoid and the polyethylene liner occurs as well as the amount of subluxation generated by that impingement. MATERIALS AND METHODS: Five glenoid component versions (5° anteversion; neutral; 5°, 10°, and 20° retroversion) and 7 polyethylene liner rotations (20° and 10° anterior; neutral; 10°, 20°, 30°, and 40° posterior) were considered, resulting in 35 different clinically representative models...

The risks and complication profile of reverse total shoulder arthroplasty (RSA) in rheumatoid arthritis (RA) patients has yet to be clearly defined as most studies have small cohorts. Using a large inpatient database, the purpose on our study was to determine the overall demographics, hospitalization characteristics, and early complication rates in rheumatoid patients and compared these to rotator-cuff arthropathy patients without RA undergoing RSA. Utilizing United States Nationwide Inpatient Sample from 2010 to 2013, we evaluated a total of 919 RA RSA and compared them to 8097 patients without RA undergoing RSA...

BACKGROUND: Recent developments in reverse shoulder arthroplasty (RSA) have focused on changes in several design-related parameters, including humeral component design, to allow for easier convertibility. Alterations in humeral inclination and offset on shoulder kinematics may have a relevant influence on postoperative outcome. This study used a virtual computer simulation to evaluate the influence of humeral neck shaft angle and glenoid lateralization on range of motion in onlay design RSA...

BACKGROUND: Pseudoparalysis remains one of the most challenging conditions in shoulder surgery. Long thought of as an unsolvable problem, recent advances in surgical techniques offer potential return of overhead motion in the setting of massive irreparable rotator cuff tears. This article summarizes the available literature including existing definitions and the results of different treatment approaches regarding range of motion, outcome scores, and reversal. METHODS: In accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a systematic review of the MEDLINE database, Cochrane database, Physiotherapy Evidence Database, and Google Scholar database was performed for studies that defined a preoperative shoulder group as having pseudoparalysis...

INTRODUCTION: Scapular notching after RSA may, in part, be related to a patient's scapular morphology. The purpose of this study was to develop a novel 3D measurement technique to describe infraglenoid tubercle morphometry. We hypothesize that the parameters describing infraglenoid tubercle would be normally distributed and would correlate with individual's demographics and glenoid morphometry. MATERIALS AND METHODS: A group of 110 subjects treated with RSA were evaluated...
