Evaluation of satisfaction and durability after hemiarthroplasty and total shoulder arthroplasty in a cohort of patients aged 50 years or younger: An analysis of discordance of patient satisfaction and implant survival
Background: Shoulder arthroplasty in individuals aged 50 years or younger reportedly leads to worse outcomes than in older patients. Current methods of determining survivorship may be inadequate and may not reflect actual patient definitions of satisfaction. The purpose of this study is to evaluate and contrast the survival of...
Trabecular Bone Microarchitecture and Characteristics in Different Regions of the Glenoid
Success of shoulder surgery depends on implant fixation to the glenoid trabecular bone. The purpose of this study was to evaluate the anatomic characteristics of the normal glenoid trabecular bone microarchitecture to help assist in implant design and provide data for finite element analyses. Eight cadavers without evidence of ...
Inferior Glenosphere Placement Reduces Scapular Notching in Reverse Total Shoulder Arthroplasty
Scapular notching is a common complication after reverse shoulder arthroplasty and has been associated with poor clinical outcomes. Factors associated with notching include neck shaft angle and glenosphere position. The goal of this study was to evaluate the incidence of notching with an eccentric glenosphere that allows for...
Managing and recognizing complications after treatment of acromioclavicular joint repair or reconstruction
Complications of the acromioclavicular joint injuries can occur as a result of the injury itself, conservative management, or surgical treatment. Fortunately, the majority of acromioclavicular surgeries utilizing modern techniques and instrumentation result in successful outcomes. However, clinical failures do occur with...
Management of complications after reverse shoulder arthroplasty
Reverse total shoulder arthroplasty (RTSA) has become the treatment of choice for patients with rotator cuff arthropathy. Complication rate after RTSA has been reported to be three to five times that of conventional total shoulder arthroplasty. Intraoperative and postoperative complications include neurological injury, infection...
A Comparison of the Lateral Decubitus and Beach-chair Positions for Shoulder Surgery: Advantages and Complications
Arthroscopic or open shoulder surgery can be performed using the lateral decubitus or beach-chair position. Advantages of the lateral decubitus position include better visualization and instrument access for certain procedures and decreased risk for cerebral hypoperfusion. Complications associated with this position include...
Management of Propionibacterium acnes infection after shoulder surgery
Propionibacterium acnes (P. acnes) is a gram-positive anaerobic bacillus commonly isolated from the flora of the face, chest, and axilla region. It has emerged as a major pathogen responsible for postoperative shoulder infections after both arthroscopy and arthroplasty procedures. Patients with P. acnes shoulder infection typically...
Reverse Shoulder Arthroplasty: Indications and Techniques
Glenohumeral arthritis includes osteoarÂthritis, rheumatoid arthritis, and post-trauÂmatic arthritis has been treated successfully with total shoulder arthroplasty for many years.
Total Shoulder Arthroplasty for Primary Shoulder Osteoarthritis
Arthritis affecting the shoulder includes osteoarthritis, rheumatoid arthritis, osteonecrosis, posttraumatic arthritis, cuff tear arthropathy...
Management of Acromioclavicular Joint Injuries
Acromioclavicular joint injuries are among the most common shoulder girdle injuries in athletes and most commonly result from a direct force to the acromion with the arm in an adducted position.Acromioclavicular joint injuries often present with associated injuries to the glenohumeral joint, including an increased incidence of...
