Percutaneous Rupture of Zygaphyseal joint Synovial Cysts: Prospective Review of Nonsurgical Management

IRB Number: 11107

Institutional Review Board, Hospital for Special Surgery

July 11, 2011

The safety of study participants is our top priority. The trial is approved and periodically reviewed by an Institutional Review Board (IRB), which includes doctors, administrators, ethicists, and members of the general public. The safety of clinical trials is reviewed by the U.S. Food and Drug Administration.

Before enrolling in a clinical trial, the investigator will explain the purpose of the trial, its expected benefits, any possible risks or side effects, and what your role will be. This is the time to ask questions! If you want to join the trial, you must sign the informed consent documents. You can leave a clinical trial at any time without penalty.
