Incidence of pedicle breach following open and minimally invasive spinal instrumentation: A postoperative CT analysis of 513 pedicle screws applied under fluoroscopic guidance

, 2020
Background: Even though pedicle screw application is a common procedure, and in-spite of spine surgeons being proficient with the technique, mal-positioning of pedicle screws can still occur.

Hydroxyapatite coating improves fixation of pedicle screws

, 2002
We investigated the effects of hydroxyapatite (HA) coating on the purchase of pedicle screws. A total of 23 consecutive patients undergoing lumbar fusion was randomly assigned to one of three treatment groups. The first received uncoated stainless-steel

Three‐Dimensional Scaffolds for Bone, Soft Tissue, and Periodontal Regeneration

Journal of Periodontal Research, EarlyView.
Three‐dimensional scaffolds offer tissue‐specific control of architecture, mechanics, porosity, and functionalisation to improve bone, soft tissue, and periodontal regeneration. ABSTRACT The oral cavity presents three distinct regenerative challenges: restoration of alveolar bone volume and stability, augmentation of soft mucogingival tissues, and ...

Cutting Flute and Thread Design on Self-Tapping Pedicle Screws Influence the Insertion Torque and Pullout Strength

Applied Sciences, 2022
Self-tapping screws are commonly used in trauma and maxillofacial surgery and are increasingly used for pedicle screw insertions. In order to evaluate how the quantity and length of cutting flutes on self-tapping pedicle screws affect the insertion ...

Intra-operative computer navigation guided cervical pedicle screw insertion in thirty-three complex cervical spine deformities

Journal of Craniovertebral Junction and Spine, 2010
Background: Cervical pedicle screw fixation is challenging due to the small osseous morphometrics and the close proximity of neurovascular elements. Computer navigation has been reported to improve the accuracy of pedicle screw placement. There are very

Comparative Analysis of Three Vertebral Screw Placement Directions in Anterior Thoracolumbar Fracture Surgery: A Finite Element Study

Orthopaedic Surgery, Volume 17, Issue 5, Page 1464-1477, May 2025.
This study compares the biomechanical effects of three anterior fixation systems in thoracolumbar surgery—HXTL, NHXTL, and Medtronic's CD Horizon ANTERIOR. Finite element analysis evaluates stress and displacement across vertebral bodies and support structures under varying load conditions. Results indicate the HXTL system minimizes nail–rod stress yet

Factors and Experiences Associated With Unscheduled Hospital Readmission After Lateral Lumbar Interbody Fusion: A Case–Controlled Study

Orthopaedic Surgery, Volume 17, Issue 5, Page 1389-1396, May 2025.
The research utilized a case–control approach to contrast patients experiencing unscheduled readmissions with those undergoing planned readmissions due to staged surgery. Findings indicated a 3.88% rate of unscheduled readmissions, mainly linked to adjacent segment disease, with 3.35% necessitating reoperation.
