The elbow joint is a complex structure that provides an important function as the mechanical link in the upper extremity between the hand, wrist and the shoulder. The elbow's functions include positioning the hand in space for fine movements, powerful grasping and serving as a fulcrum for the forearm. Loss of elbow function can severely affect activities of daily living. It is important to recognize the unique anatomy of the elbow, including the bony geometry, articulation, and soft tissue structures. The biomechanics of the elbow joint can be divided into kinematics, stabilizing structures in elbow stability, and force transmission through the elbow joint. The passive and active stabilizers provide biomechanical stability in the elbow joint. The passive stabilizers include the bony articular geometry and the soft tissue stabilizers. The active stabilizers are the muscles that provide joint compressive forces and function. Knowledge of both the anatomy and biomechanics is essential for proper treatment of elbow disorders.

Literature regarding osteochondral lesions in patients following elbow dislocation is scarce. The aim of this study was to examine osteochondral lesions on MRI in patients following simple elbow dislocations and evaluate inter-rater reliability between radiologists and orthopedic surgeons at different levels of experience. In this retrospective, single-center study, 72 MRIs of patients following simple elbow dislocations were evaluated.

: Periprosthetic joint infection (PJI) after shoulder arthroplasty is often treated with a two-stage approach, but the data on the mid- to long-term outcomes remain scarce. This study aimed to evaluate the clinical outcomes of two-stage revision arthroplasty for shoulder PJI with a minimum follow-up of five years. : This retrospective study identified 59 shoulders in 58 patients who underwent the first stage of a two-stage revision arthroplasty for shoulder PJI at our institution between 2007 and 2018.

Purpose: Ligamentous elbow dislocations often affect young patients with high functional and athletic demands. After reduction and clinical examination of joint stability, further treatment options are, therefore, the subject of controversial debate. In order to be able to advise patients adequately, an assessment of the possible return-to-sport based on experience is necessary.

Background: The treatment of patients who suffer a proximal humeral fracture (PHF) remains controversial. The purpose of this study was to find consensus among experts using a validated iterative process in the treatment of patients after a PHF.
Methods: The Neer Circle is an organization of shoulder experts recognized for their service to the American Shoulder and Elbow Surgeons.

Introduction: The aim of our study was to describe a new anteromedial approach that allows exposure of the anteromedial facet of the coronoid process and to characterize the position of the median nerve's motor branches relative to this approach in relation to elbow positioning.
Material And Methods: We performed 16 anteromedial approaches on fresh anatomical specimens. The minimum distance between the medial edge of the trochlea and the second branch of the median nerve was measured in three elbow positions: forearm in supination with the elbow extended, forearm in pronation with the elbow extended, and forearm in supination with the elbow flexed at 90 °.
