Complications of Elbow Arthroscopy

Elbow arthroscopy is generally regarded as having a relatively high rate of complications when compared to other types of arthroscopy.  This is based primarily on a landmark study that reviewed elbow arthroscopy performed from 1980-1998.  Despite this the frequency with which elbow arthroscopy is being performed has increased and the indications have broadened.  This study seeks to provide a more contemporary estimate of the complication rates associated with elbow arthroscopy as the procedure has become more commonplace.  This will be accomplished through a review of medical records by billing code to identify all elbow arthroscopy cases performed from January 2002 through December 2011 by Dr. Charles Cassidy and Dr. Jennifer Hoffman to identify complications related to elbow arthroscopy.  A letter with a questionnaire asking about elbow motion will be sent to patients with follow up times of less than 6 weeks as well.

A Retrospective Analysis of Outcome in Patients Treated for Congenital Elbow Dislocation with Conservative Management

This study looks to analyze the results of a series of patients who were treated non-surgically for what was determined to be a congenital dislocation of the elbow over the past 5 years. The standard of care for the congenital dislocation of the elbow is non-surgical treatment; however, because it is a rare finding, few studies have evaluated long-term follow up of patients treated in this manner. The patients seen by the clinic are between the ages of 3 and 18; most of them presented during the early adolescence though some were noted to have the disorder earlier on, typically in association with a more widespread musculoskeletal disorder. The goal of the study is to analyze the outcome of the conservative management of these patients using both patient-described level of function and range of motion on physical exam.

Length of Stay after Total Joint Surgery: Does Day of Surgery Matter?

The current body of research has established that accelerated perioperative hospital care leads to at least as quick a recovery as an extended hospital postoperative recovery, and in some cases has in fact led to a quicker recovery after returning home. However, there are no studies that could be found in the literature to compare the length of postoperative hospital stay for total joint replacement patients in terms of the day of the week on which the operation was performed.

The issue of shortened hospital stay is at the forefront of modern medicine. Many articles have been published concerning benefits of a shorter hospital stay when augmented with better preoperative education in terms of patient recovery and in terms of reduction in cost to the hospital and healthcare system in general, while not increasing adverse postoperative outcomes.The allocation of health resources is a mainstay of current healthcare policy making and is implicated in the general reform of the healthcare system. By studying in particular the role of selection of an operative day in terms of shortening hospital stay for orthopedic patients and hence reducing cost, one can contribute to a body of knowledge that would allow for a vast reduction in healthcare spending overall. **To be presented at 2013 AAOS Annual Meeting
