i) Study Design: Systematic review and critical analysis
ii) Grade B evidence of PJK risk factors: Greater sagittal plane correction (both EOS and AIS), increased number of distractions and posterior element disruption (EOS only), longer fusion constructs, higher pre-operative thoracic kyphosis and lumbar lordosis, and posterior (as opposed to anterior) constructs (AIS only).
