Insertional torque and pullout strength of pedicle screws versus titanium suture Anchors: Towards development of a novel proximal junctional kyphosis prevention technique

Proximal junctional kyphosis (PJK) is a common and devastating complication after spinal deformity surgery with a high need for revision surgery. PJK often leads to poor patient outcomes and large societal costs, which has led to the development of multiple prophylactic methods which have yet to eli...

PJK often leads to poor patient outcomes and large societal costs, which has led to the development of multiple prophylactic methods which have yet to eliminate PJK. A novel method for PJK prevention includes placing suture anchors, rather than pedicle screws, above the spinal construct to function as a tether. This biomechanical investigation examined the insertional torque and pullout strength of pedicle screws compared to suture anchors on 6 cadaveric vertebrae (12 pedicles). The mean insertional torque was 0.802 ± 0.477 Nm for pedicle screws and 0.368 ± 0.310 Nm for suture anchors (p = 0.047).

A novel method for PJK prevention includes placing suture anchors, rather than pedicle screws, above the spinal construct to function as a tether.
