Appraisal of the Presence of Spin in Abstracts of Systematic Reviews and Meta-analyses Regarding Free Bone Block Procedures for Glenohumeral Instability

Spin is highly prevalent in abstracts of systematic reviews and meta-analyses investigating FBB for glenohumeral instability. Associations between spin and both year and journal of publication were identified. These results suggest that surgeons should use full texts to help inform conclusions when using systematic reviews and meta-analyses to determine the efficacy and safety of FBB for glenohumeral instability.
