An atypical pyoderma gangrenosum mimicking a post surgical cutaneous and subcutaneous infection is being reported for the first time in international literature after knee replacement surgery with the operation site being the starting point of pyoderma gangrenosum. Orthopedic surgeons and general surgeons should be aware of the existence of this disease and its association with surgical trauma.

Carbon-fiber-reinforced polyetheretherketone implants offer several benefits over traditional metal implants. Their radiolucent property permits improved, artifact-free radiographic imaging. Their lower modulus of elasticity better matches that of bone. Their fatigue strength is greater than most metal implants. This article reviews the use of these implants in orthopedic surgery, including tre...

We performed a retrospective review comparing morbidity and mortality outcomes at a single institution before and after the establishment of a dedicated trauma room. The pur...

Study Design Retrospective study. Objective Minor trauma, even from a simple fall, can often cause cervical myelopathy, necessitating surgery in elderly patients who may be unaware of their posterior longitudinal ligament ossification (OPLL). The aim of this study is to determine the influence of trauma on the neurologic course in patients who have undergone surgery for cervical OPLL. Methods P...

OBJECTIVES Orthopaedists often speculate how weather and school schedule may influence pediatric orthopedic trauma volume, but few studies have examined this. This study aims to determine: how do weather patterns, day, month, season and public school schedule influence the daily frequency of pediatric orthopedic trauma consults and admissions? METHODS With IRB approval, orthopedic trauma data...

Introduction: Spontaneous retroperitoneal hematoma is a relatively rare condition that usually occurs in patients receiving anticoagulation therapy or those with a history of hemophilia. The presentation may vary from mild abdominal discomfort to acute hemodynamic collapse. Given the potential for exsanguination, it is important to detect this potentially life-threatening condition early for ap...
