Primary total hip replacement (THR) surgery is the most commonly performed and successful reconstructive procedure in orthopaedic surgery. We performed a survey of Irish Orthopaedic consultants to elucidate current practices of primary THR in elderly and young patients and identify changing trends. There was an 83% response rate. Most respondents use a cemented THR in elderly patients. 69% use a different THR in younger patients compared to older patients. 9% refer younger patients to hip replacement specialist consultant colleagues. 70% report changing to a new implant or new technique in younger patients and 45% use a hybrid THR, 15% an uncemented THR, 15% perform hip resurfacing and 47% use different bearing surfaces. Only 17% use the Charnley hip prosthesis in younger patients. Young and active patients will place high demands on a new THR and newer techniques, implants and bearing surfaces are being adopted in the hope of better outcomes.
