The pedicle screw-rod system is an acceptable method of reconstructive surgery after resection of sacroiliac joint tumours [PDF]

, 2016
Hemipelvic resections for primary bone tumours require reconstruction to restore weight bearing along anatomic axes. However, reconstruction of the pelvic arch remains a major surgical challenge because of the high rate of associated complications.

Effect of thread profile on bending strength of pedicle screw [PDF]

, 2021
Current pedicle screw designs have not achieved strong bending strength due to varying bone density among patients. Osteoporosis further presents complications in screw fixation and instrumentation failure due patients having less dense bones.

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.

Biomechanical study of C1 posterior arch crossing screw and C2 lamina screw fixations for atlantoaxial joint instability

Journal of Orthopaedic Surgery and Research, 2020
Background The biomechanics of C1 posterior arch screw and C2 vertebral lamina screw techniques has not been well studied, and the biomechanical performance of the constructs cannot be explained only by cadaver testing.

Biomechanical arrangement of threaded and unthreaded portions providing holding power of transpedicular screw fixation

, 2017
Background: Failure of pedicle screw is a major concern in spinal surgery. The threaded and unthreaded portions of the pedicle screw provide the ability to anchor and squeeze the surrounding bone, respectively.

Factors influencing the pedicle screw fixation stability in patients with unstable lumbar and thoracolumbar spine injuries

Инновационная медицина Кубани, 2020
Background. One of the reasons for the lack of standardized approaches to treating lumbar and thoracolumbar spine traumatic injuries is inconclusive information on relative contribution of various factors to pedicle screw fixation stability.Objective. To

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

Arthroscopy Techniques, EarlyView.
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.

Combined Anterior Cruciate Ligament Reconstruction and Lateral Extra‐articular Tenodesis With Augmented Continuous Iliotibial Band Autograft

Arthroscopy Techniques, EarlyView.
Abstract The purpose of this technical note is to describe a reproducible surgical technique for anterior cruciate ligament reconstruction combined with a lateral tenodesis using a continuous iliotibial band autograft that allows self‐augmentation of graft diameter without the need for additional tendon harvesting.
