Morphometric Analysis of Subaxial Cervical Vertebra Pedicles in the Turkish Population
TomographyBackground/Objectives: One of the surgical interventions applied in the cervical region is the pedicle screw method. The cervical pedicle screw is stronger than any other screw method; however, use of the cervical pedicle screw is limited due to the ...

Assesment [sic] of cement augmentation and screw trajectory on pedicle screw fixation in osteoporotic vertebrae [PDF]
, 2010 Internal fixation of osteoporotic spines for fracture or deformity is currently difficult, owing to failure at the bone- implant interface. This study aims to ascertain whether pedicle screw trajectory and pedicle cortex retention can independently ...

Analysis of Risk Factors for Adjacent Segment Disease After Lumbar Facet Joint Fusion
Orthopaedic Surgery, Volume 18, Issue 3, Page 433-442, March 2026.This schematic illustrates a novel posterior lumbar fusion procedure targeting L4–L5 segments, with emphasis on the position of split bone and the precise site of bone grafting. Featuring “active generation + real‐time verification” and intact posterior tension band, this technique achieves precise segmental lordosis restoration with enhanced ...
