pedicle screw

pedicle screw

A rigid surgical implant used to stabilize adjacent spinal segments in spinal fusion surgery. Pedicle screws have been used to treat spinal disorders, including those caused by spinal cancer, congenital anomalies, trauma, and chronic pain syndromes. Potential complications may include increased pain, infection, or mechanical failure (breakage of the screws or the rods that connect them).

It is firmly connected to patient's body through one of the three platforms; a clamped bridge attached to spinous process, a Hover-T bridge attached through three pins to patient' bony anatomy or a bed mount device with only one pin connecting the Hover-T bridge to the patients' spine.8 Spineassist is used in drilling as well as for thoracic and lumbar pedicle screw insertion procedures.20
A retrospective review compared 50 patients who had 3DP spinal biomodels composed of polystyrene created prior to surgical correction of Lenke Type 1 adolescent idiopathic scoliosis with 76 patients who received the standard of care (no biomodeling) and showed that the treatment group had a significantly (p = 0.02) decreased rate of pedicle screw misplacement in patients with a Cobb angle of >50 degrees [6].
