Erratum to: Is Tip Apex Distance As Important As We Think? A Biomechanical Study Examining Optimal Lag Screw Placement

What Is the Relevance of the Tip-Apex Distance as a Predictor of Lag Screw Cut-Out?

Using a simple mathematical formulation, the relationship between the position of the lag screw tip (relevant to both intramedullary and extramedullary devices) and the concept of tip-apex distance (TAD) was derived. TAD is widely used in operating theaters as a surgical guideline in relation to the fixation of trochanteric fractures, and in clinical studies as a predictor of lag screw cut-out....

Is science as global as we think?

A cornerstone of scientific practice is the perceived freedom with which knowledge is disseminated. But does the scientific community make good use of all that is available? Researchers have, on occasion, been accused of preferentially citing the work of colleagues close to home while ignoring those from other parts of the world [1,2]. Such practices, if true, raise serious concerns about the f...
