The FDA has the authority to require sponsors to perform a post-approval study (or studies) at the time of approval of a premarket approval (PMA), humanitarian device exemption (HDE), or product development protocol (PDP) application. Post-approval studies can provide patients, health care professionals, the device industry, the FDA and other stakeholders information on the continued safety and effectiveness (or continued probable benefit, in the case of an HDE) of approved medical devices. This database allows you to search Post-Approval Study information by applicant or device information.

Study Objectives The study design is a multi-center, single arm, prospective cohort study.
Study Population Study population is as per device indication. Patients who underwent Birmingham Hip Resurfacing (BHR) System, a metal on metal resurfacing artificial hip replacement system, surgically implanted to replace a hip joint. The BHR System is intended for patients who, due to their relatively youneger age or increased activity level may not be suitable for traditional total hip arthroplasty, due to an increased possibility of requiring future ipsilatcral hip joint revision.
Sample Size The sample size is 350 patients.
Key Study Endpoints Study endpoints include Harris Hip Score and device survival.
Follow-up Visits and Length of Follow-up Patients will undergo clinical and radiographic examinations for the first five years of follow-up with a final clinical and radiographic examination at 10 years. Subjects will receive annual questionnaire follow-up in years 6 through 9.
