You are invited to take part in a patient registry research study. A patient registry is an organized way to collect observational data from a large group of patients undergoing the same procedure. Observational data means that your surgeon will not do anything other than the standard of medical care, regardless of your participation in this registry. The registry will ‘observe’ or collect data from your medical records, preparation phase, procedure and recovery. A person who takes part in a registry is called a subject, or a registry participant.
