Background: The purpose of this study was to examine the mid-term functional outcomes, radiographic results,and revision rates of patients treated with the Delta Xtend Reverse Shoulder System for both primary and revisionarthroplasty indications.Methods: A retrospective review was conducted of records for all individuals who underwent a reverse shoulderarthroplasty using the Delta Xtend Reverse...

Total shoulder arthroplasty and shoulder hemiarthroplasty have been the traditional method for treating a variety of shoulder conditions, including arthritis, cuff tear arthropathy, and some fracture types. However, these procedures did not provide consistently good results for patients with torn rotator cuffs. The development of the reverse prosthesis by Grammont in the late 20th century revol...

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...

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 and purpose - For more than half a century, stemmed hemiarthroplasty (SHA) has been used in the treatment of comminuted and displaced fractures of the proximal humerus. Reverse shoulder arthroplasty (RSA) has been increasingly popular in cases where it is difficult to obtain satisfactory fixation of the tuberosities. We report revision rates and reasons for revision after shoulder ar...

OBJECTIVE The purpose of this article is to provide a review of indications for shoulder arthroplasty, describe preoperative imaging assessment, present new and modified designs of shoulder arthroplasty, illustrate normal and abnormal postoperative imaging findings, and review key radiographic measurements. CONCLUSION Knowledge of the physiologic purpose, orthopedic trends, imaging findings, ...

Proximal humerus fractures are the third most common fracture in elderly patients. Hemiarthroplasty has been the treatment of choice in patients with bone quality and fracture patterns not amenable to open reduction and internal fixation. Reverse total shoulder arthroplasty is a newer option that appears to be less dependent on tuberosity healing than hemiarthroplasty. The authors hypothesized ...

BACKGROUND The reported outcomes of shoulder arthroplasty in patients under the age of fifty years are worse than those in patients over fifty. While there are several possible explanations for this finding, we explored the possibility that patients who had a primary shoulder arthroplasty when they were under fifty years of age differed from those who had the procedure when they were over fifty...

OBJECTIVE The purpose of this article is to provide a review of the indications for shoulder arthroplasty, describe preoperative imaging assessment, present new and modified designs of shoulder arthroplasty, illustrate normal and abnormal postoperative imaging findings, and review key radiographic measurements.
