Acetabular cup position and risk of dislocation in primary total hip arthroplasty.

abstract：BACKGROUND AND PURPOSE:Hospital volume has been suggested to be one of the best indicators of adverse orthopedic events in patients undergoing THR surgery. We therefore evaluated the effect of hospital volume on the length of stay, re-admissions, and complications of THR at the population level in Finland. METHODS:30,...
