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...

BACKGROUND Following shoulder arthroplasty, any well-planned rehabilitation program should include muscle strengthening. However, it is not always clear how different external loads influence shoulder kinematics in patients with shoulder prostheses. The objective of this study was to describe shoulder kinematics and determine the contribution of the scapulothoracic joint to total shoulder motio...

BACKGROUND The aim of this study was to determine if agreement could be obtained on guidelines regarding the ideal minimum age for a reverse shoulder replacement, as well as on post-operative rehabilitation and restrictions imposed on patients having undergone this procedure. MATERIAL AND METHODS A two-round Web-based Delphi consensus study was undertaken. An international group of experts in...

Advanced glenohumeral osteoarthritis can transform glenoid morphology and, in some cases, is found in association with severe glenoid retroversion. The associated glenoid retroversion leads to difficulty in fixation of the glenoid component in reverse total shoulder arthroplasty. In the context of extreme glenoid wear, structural grafts can be used to restore glenoid volume and version in order...

Synovial chondromatosis affecting the glenohumeral joint is rare. Treatment primarily consists of arthroscopic loose body removal and synovectomy. Shoulder arthroplasty has been mentioned in the literature as a treatment option for patients with coexisting arthritis, although the results have been underreported. The case of an 84-year-old man with long standing synovial chondromatosis of the sh...

Osteoarthritis of the shoulder is a common condition in the aging population, and it can have profound effects on patients' quality of life. The anatomic total shoulder arthroplasty is a well-described treatment modality resulting generally excellent outcomes. The objective of this review is to discuss the technical aspects of primary anatomic total shoulder arthroplasty, and to provide a frame...

The treatment of proximal humeral bone loss with its associated pain and loss of function continues to be a challenge for the orthopaedic surgeon. Current options for this condition include hemiarthroplasty or total shoulder arthroplasty with the addition of bone grafting. Unfortunately, due to residual instability, these options have not given the desired results. Reverse shoulder arthroplasty...

OBJECTIVES To obtain outcomes data on anatomical and reverse total shoulder arthroplasty by analysis of clinical scores and standard radiographs. SUBJECT SELECTION AND ENROLLMENT 400 consecutive series of patients replaced with anatomical and reverse total shoulder arthroplasty (minimum 3 years follow-up). STUDY DESIGN retrospective monocenter. PREOPERATIVE ASSESSMENT Demographics, clinic...
