Introduction: Since the introduction of the Grammont style reverse total shoulder arthroplasty (RTSA), the humeral stem design has been modified with improved clinical outcomes. Two distinct humeral designs have been utilized extensively: the inlay where the humeral tray is seated within the metaphysis and the onlay design where the humerus tray sits on the metaphysis at the level of the humeral neck cut. The purpose of this systematic review is to determine if there are differences in clinical outcomes and complication rates between these designs. Read More

Head-split fractures are proximal humerus fractures (PHF) that result from fracture lines traversing the articular surface. While head-split fractures are rare, surgical treatment of these complex injuries can be extremely challenging and is associated with high rates of complications. Treatment using primary reverse shoulder arthroplasty (RSA) has been associated with moderate complication rates and reproducible clinical results. Read More

Mount Sinai Health System, New York, NY, USA.

Background: Reverse total shoulder arthroplasty is a common treatment for patients with rotator cuff arthropathy who have failed a prior rotator cuff repair. Latissimus dorsi transfer can be performed simultaneously to reverse total shoulder arthroplasty for patients with preoperative external rotation deficiency. Current literature is limited with several studies providing functional and pain improvements at short-term follow-up; however, there is a deficit in data regarding mid-term outcomes. Read More

Division of Orthopaedic Surgery, Department of Surgery, Sidra Medicine, Doha, Qatar.

Purpose: Scapular fractures are uncommon injuries that account for up to 1% of all fractures and 5% of all shoulder girdle fractures. Moreover, most of the evidence on the treatment of scapular fractures stems from case series, with paucity of comparative studies. Despite the lack of standardized criteria for the operative treatment of scapular fractures, a set of suggested radiological parameters has been recently reported. Read More

Imaging plays a key role in the assessment and management of traumatic shoulder injuries, and it is important to understand how the imaging details help guide orthopedic surgeons in determining the role for surgical treatment. Imaging is also crucial in preoperative planning, the longitudinal assessment after surgery and the identification of complications after treatment. This review discusses the mechanisms of injury, key imaging findings, therapeutic options and associated complications for the most common shoulder injuries, tailored to the orthopedic surgeon's perspective.

Department of Shoulder and Elbow Surgery, Center for Musculoskeletal Surgery, Charité-Universitaetsmedizin Berlin, Berlin, Germany.

Background: Metallic humeral and glenoid lateralized implants have been developed to prevent common problems that can emerge using Grammont's concept (ie, medialization of center of rotation, decreased humeral offset, scapular notching) in reverse shoulder arthroplasty. The purpose of this study was to evaluate the clinical and radiological results of metallic humeral and glenoid lateralized implants for cuff tear arthropathy (CTA) and primary osteoarthritis (OA).

Methods: In this prospective study, patients with CTA or OA who underwent reverse shoulder arthroplasty using augmented base plates for glenoid lateralization and a "curved stem" design for the humeral side were included. Read More

With the increased use of reverse shoulder arthroplasty, the complication of postoperative scapular fracture is increasingly recognized. The incidence is variable and dependent on a combination of factors including patient age, sex, bone mineral density, diagnosis of inflammatory arthritis, acromial thickness, and implant-related factors. Acromial stress reactions are a clinical diagnosis based on a history and physical examination. Read More

Department of Orthopedic Surgery, Asan Medical Center, University of Ulsan College of Medicine, Seoul, Korea.

Background: The treatment approach for proximal humeral fractures is determined by various factors, including patient age, sex, dominant arm, fracture pattern, presence of osteoporosis, preexisting arthritis, rotator cuff status, and medical comorbidities. However, there is a lack of consensus in the literature regarding the optimal treatment for displaced proximal humeral fractures. This study aimed to assess and quantify the decision-making process for either conservative or surgical treatment and the choice of surgical method among shoulder surgeons when treating proximal humeral fractures.

Department of Orthopedic Trauma, First Affiliated Hospital of Jinzhou Medical University, Jinzhou, China. Electronic address:

Background: Because of the irregular shape of the scapula and the different types of fractures, a standard internal fixation device is lacking in clinical practice, even though there are many options available. This study aimed to compare the therapeutic efficacy of titanium anatomic and reconstructive plates for extra-articular fractures of the scapula (Miller types IIb, IIc, and IV).

Methods: A retrospective study of 41 patients who underwent treatment for extra-articular fractures of the scapula between March 2017 and March 2020 was conducted. Read More

UTHealth Science Center Houston, 6431 Fannin Street, Houston, TX 77030, United States of America.

Background: Scapular fractures in the pediatric population are rare, and medical literature is lacking regarding these specific injuries in the pediatric population. Prior studies have shown that scapular fractures resulting from blunt chest trauma have been associated with significant morbidities in adults, and that a majority of scapular fractures are missed on chest X-ray (CXR) and seen on computerized tomography only (SOCTO). Further guidance is needed regarding the prevalence of coinciding injuries in the pediatric population and the modality for diagnosis. Read More

Division of Orthopaedics and Trauma Surgery, La Tour Hospital, Meyrin, Switzerland.

The initial reverse shoulder arthroplasty (RSA), designed by Paul Grammont, was intended to treat rotator cuff tear arthropathy in elderly patients. In the early experience, high complication rates (up to 24%) and revision rates (up to 50%) were reported.The most common complications reported were scapular notching, whereas clinically more relevant complications such as instability and acromial fractures were less commonly described.
