Risk factors for intraoperative calcar fracture in cementless total hip arthroplasty.

abstract：BACKGROUND AND PURPOSE:The Norwegian Cruciate Ligament Register (NCLR) was founded in 2004. The purpose of the NCLR is to provide representative and reliable data for future research. In this study we evaluated the development of the registration rate in the NCLR. METHODS:The Norwegian Patient Register (NPR) and the e...
