Background The objective of this study was to assess the pullout force of a novel sharp-
tipped screw developed for single-step, minimally invasive pedicle screw placement guided …

Background: Standard fluoroscopic navigation and stereotactic computed tomography–
guided lumbar pedicle screw instrumentation traditionally relied on the placement of …

Object Minimally invasive pedicle screws inserted vertically (that is, dorsoventrally) through
the pedicle, as opposed to the more common coaxial technique, offer potential advantages …

Study Design: Description of a navigated, single-step, minimally invasive technique for the
placement of pedicle screws. Objective: To describe a new technique for minimally invasive …

Objective This study retrospectively assessed the accuracy of placement of lumbar pedicle
screws placed by a single surgeon using a minimally-invasive, intra-operative CT-based …

OBJECTIVE Percutaneous pedicle screw insertion (PPSI) is a mainstay of minimally
invasive spinal surgery. Traditionally, PPSI is a fluoroscopy-guided, multistep process …

Study Design: Cadaveric study. Summary of Background Data: Pedicle screw fixation is an
established means of stabilizing the thoracic and lumbar spine. However, there are …

Study Design: Prospective case series. Objective: SSPSS (single step pedicle screw system)
was developed for minimally invasive spine surgery. We performed this study to report on …

Object This study was conducted to assess the in vivo safety and accuracy of percutaneous
lumbar pedicle screw placement using the owl's-eye view of the pedicle axis and a new …
