Removable anchoring pedicle screw

, 2010
A removable anchoring pedicle screw includes an implant mounting screw, an anchor screw, and a nose piece. The anchor screw is configured to be rotated relative to the implant mounting screw such that the nose piece engages an expandable anchor.

Determination of Proximal Junctional Kyphosis in Adolescent Idiopathic Scoliosis Correction Fusion using Pedicle Screw Versus Hook Plus Screw Pedicle Instrumentation

, 2021
Introduction: Spinal instrumentation in idiopathic adolescent scoliosis (AIS) aims to correct spinal deformity, and maintain spinal stability. Proximal junctional kyphosis (PJK) is a relatively common postoperative complication.

The Bony Density of the Pedicle Plays a More Significant Role in the Screw Anchorage Ability Than Other Regions of the Screw Trajectory

Orthopaedic Surgery
Objective Osteoporosis is a crucial risk factor for screw loosening. Our studies indicate that the bone mineral density (BMD) in the screw trajectory is a better predictor of screw loosening than the BMD of the lumbar spine or the screw insertion ...

Independent Anatomic Double‐Bundle Anterolateral Ligament Reconstruction Using a Pedicled Gracilis Graft During Anterior Cruciate Ligament Reconstruction

Arthroscopy Techniques, Volume 15, Issue 10, October 2026.
Abstract Recent studies on the anatomy and biomechanics of the anterolateral ligament (ALL) have highlighted its fundamental role in rotational control of the knee. These findings have led to the integration of its reconstruction into anterior cruciate ligament (ACL) reconstruction strategies, in order to improve management of residual pivot shift and ...

The biomechanics of pedicle screw-based instrumentation

, 2010
There are three basic concepts that are important to the biomechanics of pedicle screw-based instrumentation. First, the outer diameter of the screw determines pullout strength, while the inner diameter determines fatigue strength.

Comparison of Surgical Outcomes Following Percutaneous Pedicle Screw Fixation and Traditional Open Pedicle Screw Fixation for Thoracolumbar Fractures Without Neurological Deficit

Journal of Nepal Health Research Council
Background: Traumatic thoracolumbar fractures are frequently encountered in blunt trauma patients. The Open pedicle screw fixation has been proven to be effective in stabilizing fractures, deformity correction, early mobilization and improving long term

Arthroscopic Posterior Cruciate Ligament Reconstruction Using a Pedicled Semitendinosus Autograft Through a Trans‐Septal Approach: A Technical Note

Arthroscopy Techniques, Volume 15, Issue 10, October 2026.
Abstract Isolated posterior cruciate ligament (PCL) ruptures are relatively uncommon among knee ligament injuries. Operative management is recommended for patients with grade III posterior knee joint laxity. The complex anatomy of the PCL, particularly its course and insertion on the femur and the tibia, makes its reconstruction technically challenging.

Investigation on pullout strength between different design of cannulated pedicle screw and osteoporosis bones to obtain an optimum design [PDF]

, 2019
Pedicle screws are widely used for the treatment of spinal instability by spine fusion. This treatment can be performed at any level in the spine (cervical, thoracic or lumbar) and prevents any movement between the fused vertebrae.

Pedicle Screw Placement Accuracy in Robot-Assisted Spinal Fusion in a Multicenter Study [PDF]

, 2023
Pedicle screw fixation is a spinal fusion technique that involves the implantation of screws into vertebral pedicles to restrict movement between those vertebrae. The objective of this research is to measure pedicle screw placement accuracy using a novel
