A quantitative accuracy assessment of the use of a rigid robotic arm in navigated placement of 726 pedicle screws.

Background: Traditional minimally invasive fluoroscopy-based techniques for pedicle screw placement utilize guidance, which may require fluoroscopic shots. Computerized tomography (CT) navigation results in more accurate screw placement. Robotic surgery seeks to establish access and trajectory with greater accuracy.

Navigated robotic assistance results in improved screw accuracy and positive clinical outcomes: an evaluation of the first 54 cases.

Computer-aided navigation and robotic guidance systems have become widespread in their utilization for spine surgery. A recent innovation combines these two advances, which theoretically provides accuracy in spinal screw placement. This study describes the cortical and pedicle screw accuracy for the first 54 cases where navigated robotic assistance was used in a surgical setting.

Focal hole versus screw stimulation to prevent false negative results in detecting pedicle breaches during spinal instrumentation.

Objective: We describe a stimulus-evoked EMG approach to minimize false negative results in detecting pedicle breaches during lumbosacral spinal instrumentation.

Methods: In 36 patients receiving 176 lumbosacral pedicle screws, EMG threshold to nerve root activation was determined using a focal probe inserted into the pilot hole at a depth, customized to the individual patients, suitable to position the stimulating tip at the point closest to the tested nerve root. Threshold to screw stimulation was also determined.

Management of rosacea-prone skin: evaluation of a skincare product containing Ambophenol, Neurosensine, and La Roche-Posay Thermal spring water as monotherapy or adjunctive therapy.

Objective: The objective of these studies was to investigate whether a skincare product containing Ambophenol, Neurosensine, and La Roche-Posay thermal spring water formulated in a highly protective packaging can have an impact in the management of rosacea-prone skin subjects.

Methods: Several studies were performed to evaluate the efficacy of this product in the management of rosacea prone skin, as either monotherapy or adjunctive therapy or to maintain the efficacy of a Metronidazole treatment. The first study was performed on 37 women aged 18-45 with added stage 2 erythro-couperosis, who applied test formula as monotherapy twice a day for 4 weeks.

Non-invasive high voltage electrical stimulation as a monitoring tool of nerve root function in lumbosacral surgery.

Objective: To verify the safety and clinical use of non-invasive high-voltage electrical stimulation (HVES) in patients with compressive radiculopathy. To test the feasibility of HVES to survey nerve root function during lumbosacral surgery.

Methods: In 20 patients undergoing lumbosacral surgery for degenerative spinal diseases, compound muscle action potentials (CMAPs) evoked by maximal HVES were bilaterally recorded throughout surgery from L3 to S2 radicular territories.
