Alignment of pedicle screws with pilot holes: Can tapping improve screw trajectory in thoracic spines? [PDF]

, 2010
Pedicle screws are placed using pilot holes. The trajectory of pilot holes can be verified by pedicle sounding or radiographs. However, a pilot hole alone does not insure that the screw will follow the pilot hole.

Abnormal Cervical Facet Orientation and Congenital Stenosis: Case Reports and Biomechanical Implications—Illustrative Cases

Clinical Case Reports, Volume 14, Issue 7, July 2026.
ABSTRACT In patients with congenital cervical stenosis, the addition of abnormal cervical facet orientation (horizontal or hypoplastic joints) may predispose to segmental instability, subluxation, and canal compromise. Full assessment of facet anatomy is essential pre‐operatively, as selected patients (e.g., those with demonstrable subluxation, widened
