We investigated the clinical and radiographic outcomes of THR performed in children and teenage patients. Patients and methods - We included 111 patients (132 hips) who underwent THR before 20 years of age. They were identified in the N...

BACKGROUND The number of total hip arthroplasties in patients under 30 years is increasing over the years. Almost all of them will face at least one or more future revisions in their life. Therefore, the implant used should have a high survival rate, and needs to be easily revisable resulting in a low re-revision rate. Several studies have evaluated the outcome of total hip arthroplasties in pa...

BACKGROUND AND PURPOSE Controversies still exist regarding the best surgical procedure in the treatment of periprosthetic infection after total hip arthroplasty (THA). Based on data in the Norwegian Arthroplasty Register (NAR), we have compared the risk of re-revision after 4 different surgical procedures: 2-stage with exchange of the whole prosthesis, 1-stage with exchange of the whole prosthe...

While these are conceptually equivalent, their initial estimates differ because computed from different incomplete data sources. I study the difference, or “statistical discrepancy,” between GDP GDI in percent document three features. First, its size does not materially shrink on average as mor...
