Is it feasible to merge data from national shoulder registries? A new collaboration within the Nordic Arthroplasty Register Association

摘要

Background: The Nordic Arthroplasty Register Association was initiated in 2007, and several papers about hip and knee arthroplasty have been published. Inspired by this, we aimed to examine the feasibility of merging data from the Nordic national shoulder arthroplasty registries by defining a common minimal data set.
