The purpose of the prospective database is to initiate data collection for a group of patients undergoing surgery of the shoulder. Long-term data collection will include information on the functional status of the patients' shoulder as well as quality of life information and radiographic results. The database will be an essential element in the development of an academic shoulder service at the University of Ottawa. Many areas in shoulder surgery are in their infancy in terms of minimally invasive techniques. Several large areas require substantial research in order to refine decision making. The database will allow these questions to be answered using a retrospective model and will provide the background information required to mount larger scale randomized controlled trials. The nature of the database information collection will also allow meaningful research to be completed by the residents in the program in a timely and cost-effective manner. This will be in keeping with the training requirements in Orthopedic surgery and will help promote interest in the area of research for the trainees.The following are examples of questions that the database information could answer through research:
