Observational Study to Evaluate Long-Term Outcome in Hip Hemiarthroplasty

This study is tracking long-term outcomes in patients who have had hip hemiarthroplasty — a partial hip replacement where only the femoral (ball) side of the joint is replaced, not the socket. This procedure is commonly used for hip fractures and avascular necrosis in older adults. By collecting follow-up data over several years using Corin hip devices, researchers aim to understand how these implants perform in real-world patients. You may be eligible if: - You are an adult (18 years or older) of any gender - You are a suitable candidate for hip hemiarthroplasty using Corin devices based on your condition (such as hip fracture, avascular necrosis, or revision of a prior partial hip replacement) - You are willing and able to attend required follow-up visits - You have signed the study consent form You may NOT be eligible if: - You have an active infection, sepsis, or bone infection at the surgical site - You do not have adequate bone quality to support a prosthesis - You have significant bone loss or metabolic bone disease - You are under legal guardianship or judicial protection - You have a serious psychiatric condition, substance abuse, or other issue that would prevent you from complying with study visits Talk to your doctor to see if this trial is right for you.
