Purpose To analyze the clinical and demographic presentation, treatment strategies, and outcomes of athletes who sustained proximal ulna stress injuries and elucidate the available evidence on management and anatomic variation. Methods A literature search was performed on the basis of the medical databases MEDLINE/PubMed and Embase. Articles repor...

Posterior impingements are most commonly seen in athletes involved in overhead-throwing sports. It is also reported in boxing and lifting heavy objects. The whole kinetic chain involved in the sport of the athlete causing the symptoms should be examined. Only if nonsurgical treatment is unsuccessful does sur- gery needs to be considered. Arthroscop...

Introduction: The readability, reliability, and quality of online hip preservation–related patient education materials from the top 20 orthopaedic academic centers in the United States were evaluated. Methods: The patient educational materials were evaluated with the following assessment tools: Flesch-Kincaid (FK) readability test, Flesch Reading...

Background: Medical students and residents rely increasingly on web-based education. Online videos provide unique opportunities to share knowledge. The objective of this study was to investigate the accuracy and quality of instructional videos on the physical examination of the elbow and identify factors influencing educational usefulness. Methods...

Background Stress radiography measures medial joint space opening of the elbow, but its value in the management of throwing athletes is unclear. The purpose of this study was to analyze the relationship between medial joint opening (gapping and excess opening) and ulnar collateral ligament (UCL) injury severity on magnetic resonance imaging, as wel...

Background Throwing athletes sustaining an ulnar collateral ligament (UCL) injury may recall a popping sensation originating from the medial elbow at the time of injury. There are no studies available that inform clinicians how to utilize this salient anamnestic information and what amount of diagnostic weight to afford to it. Purpose To assess th...

Background: The purpose of this study was to increase our understanding of the pathoanatomy of the ulnar collateral ligament (UCL) by performing a descriptive analysis of the surgical inspection of the anterior bundle in patients undergoing reconstruction. Methods: A single-surgeon series of 163 patients who underwent UCL reconstruction between...

Purpose Allografts play an important role in tendon, ligament, and bone reconstruction surgery, particularly when suitable available autologous tissue is limited. Enthusiasm for the use of allografts in reconstructive orthopedic surgery has increased over the past decade, with an increase in allograft use in a variety of procedures. The purpose of...

Objectives The purpose of this study is to analyze posteromedial fragment morphology using two-dimensional computed tomography fracture mapping and to compare posteromedial fragment morphology in various Schatzker type tibial plateau fractures. Materials & methods One hundred twenty-seven consecutive AO/OTA B- and C-type tibial plateau fractures w...

This classic discusses the original publication ‘Elbow Arthroscopy: A New Technique’ by Poehling et al, published in 1989 in The Journal of Arthroscopic and Related Surgery on the introduction of the prone position and the proximal medial portal to elbow arthroscopy. The first attempt to perform elbow arthroscopy was on a cadaveric specimen by Burm...

This classic examines the landmark publication ‘Reconstruction of the Ulnar Collateral Ligament in Athletes’ by Jobe et al, published in 1986. Dr Frank W Jobe was the first to perform and describe a standard technique for ulnar collateral ligament (UCL) reconstruction with the use of a figure-of-eight configuration and submuscular ulnar nerve trans...

Introduction: Tibial plateau fracture classification systems have limited interobserver reliability and new systems emerge. The purpose of this study was to compare the reliability of the Luo classification and the Schatzker classification for two-dimensional computed tomography (2DCT) and to study the effect of adding three-dimensional computed t...

Objectives: The purpose of this study was to assess the interobserver reliability and diagnostic accuracy for 2-dimensional (2D) and 3-dimensional (3D) computed tomography (CT)-based evaluation of tibial plateau fracture characteristics. We hypothesized that recognition of specific tibial plateau fracture characteristics is equally reliable and ac...

Brown adipose tissue (BAT) is able to convert calories into heat rather than storing them. Therefore, activated BAT could be a potential target in the battle against obesity and type 2 diabetes. This review focuses on the role of the autonomic nervous system in the activation of human BAT. Although the number of studies focusing on BAT in humans is...

Background: Computed tomography (CT) is seen as a useful diagnostic modality in preoperative planning for tibial plateau fractures. The purpose of this study was to characterize patterns of tibial plateau fractures with use of CT mapping. We hypothesized that CT mapping of fractures of the tibial plateau would reveal recurrent patterns of fragment...
