» Proximal humerus bone loss (PHBL) is a challenging issue in the setting of reverse total shoulder arthroplasty, particularly during revision surgeries. » PHBL can compromise the deltoid moment arm, soft tissue attachments, and stability of the humeral and glenoid components. » Causes of PHBL are multifactorial, and the degree of bone loss can vary widely among patients. » Treatment options include long-stem reconstruction prostheses, cementoplasty, reverse total shoulder allograft prosthesis composite reconstruction, proximal humerus replacement/endoprosthesis, and custom 3D-printed reconstruction. » Each treatment option has unique advantages and limitations, emphasizing the importance of individualized management plans tailored to patient needs.

Background: This study evaluates the accuracy of an Artificial Intelligence (AI) system, specifically a convolutional neural network (CNN), in classifying elbow fractures using the detailed 2018 AO/OTA fracture classification system.
Methods: A retrospective analysis of 5,367 radiograph exams visualizing the elbow from adult patients (2002-2016) was conducted using a deep neural network. Radiographs were manually categorized according to the 2018 AO/OTA system by orthopedic surgeons.

Introduction/background: Complex articular fractures around the knee in the elderly patient present an ongoing challenge regarding optimal treatment. While extensive research has evaluated immediate arthroplasty following fracture of the proximal femur, distal femur, proximal humerus, and elbow, relatively little focus has been given to immediate arthroplasty following complex tibia plateau fractures.
Methods: As seen with many other fractures, arthroplasty can shorten recovery and hospital stay and allow early weight-bearing with improved mobility while minimizing complications and possible future conversion arthroplasty cost.

Introduction: Treatment approaches and functional outcomes have been shown to be influenced by a patient's socioeconomic status in certain orthopaedic pathologies. In patients with proximal humerus fractures (PHFs), this study aimed to evaluate the relationship between social deprivation and (1) treatment strategy-including the choice between surgical and nonsurgical management, as well as the type of surgical intervention-and (2) patient-reported outcomes.
Methods: We retrospectively reviewed 275 displaced PHFs from a level 1 trauma center.

Aims: The epidemiology of proximal humerus fractures (PHFs) has been described in terms of incidence, fracture complexity, and general time trends, but current literature on time trends in PHF complexity is limited. This study aims to explore possible time trends in PHF complexity and report the distribution of different types of PHF from January 1944 to December 2020.
Methods: The city of Malmö, Sweden, has one emergency hospital where acute fractures are treated, and radiographs have been saved for almost a century.

Background: The incidence of proximal humerus fractures is rising, with increasing use of reverse total shoulder arthroplasty (rTSA). This study analyzed treatment trends, readmission rates, and causes of readmission.
Methods: The Nationwide Readmissions Database (NRD) was queried for admissions with a primary diagnosis of proximal humerus fracture in the U.
