Intracranial hypotension following scoliosis surgery: dural penetration of a thoracic pedicle screw

Prediction of scoliosis correction with thoracic segmental pedicle screw constructs using fulcrum bending radiographs.

STUDY DESIGN A retrospective series of 35 idiopathic scoliosis patients underwent spinal fusion with a segmental thoracic pedicle screw system. OBJECTIVE To evaluate the amount of scoliosis correction with segmental pedicle screw constructs, and assess whether the fulcrum bending radiograph can predict surgical correction. SUMMARY OF BACKGROUND DATA The fulcrum bending radiograph is highly ...

Pedicle screw versus hybrid construct instrumentation in adolescent idiopathic scoliosis: meta-analysis of thoracic kyphosis.

STUDY DESIGN A quantitative meta-analysis was conducted on publishing studies reporting results of spinal surgery in adolescent idiopathic scoliosis with instrumentation of pedicle screw or hybrid construct. OBJECTIVE The primary objective is to get overview of the power to restore thoracic kyphosis using 2 different instrumentations. SUMMARY OF BACKGROUND DATA During the past years, surger...

Thoracic pedicle screw placement: free-hand technique.

Thoracic pedicle screws provide a number of advantages over other methods of spinal fixation in treating a variety of conditions including: better pull-out strength and greater control in the sagittal, coronal and rotational planes due to increased stability to axial, bending and rotational forces by three-column fixation, fewer vertebral motion segments arthrodesed, no or lessened need for pos...

Design of a Haptic Simulator for Pedicle Screw Insertion in Pediatric Scoliosis Surgery

A medium invasiveness multi-level patient’s specific template for pedicle screw placement in the scoliosis surgery

BACKGROUND Several methods including free-hand technique, fluoroscopic guidance, image-guided navigation, computer-assisted surgery system, robotic platform and patient's specific templates are being used for pedicle screw placement. These methods have screw misplacements and are not always easy to be applied. Furthermore, it is necessary to expose completely a large portions of the spine in or...
