In the August 1, 2023 issue of Spine in the article by Rasouligandomani et al, “Proximal Junction Failure in Spine Surgery: Integrating Geometrical and Biomechanical Global Descriptors Improves GAP Score-Based Assessment”, in the Introduction, the 4th sentence is incorrect:

In about 57% of cases, mechanical complications occur around the instrumentation, especially during the first 12 months postsurgery.2

It should read:

Mechanical complications occurred in 59% of patients >=60 years old and 34% of patients <60 years old during two years postsurgery follow-up.2
