Methods are provided for planning, performing, and assessing of surgical correction to the spine during a spinal surgical procedure. These methods are implemented by a control unit through a GUI to digitize screw locations, digitize anatomical reference points, accept one or more correction inputs, and generate one or more rod solution outputs shaped to engage the screws at locations distinct from the originally digitized locations.

Systems and methods for planning, performing, and assessing spinal correction during surgery

A system and related methods for performing nerve detection during surgical access using ultrasound testing during surgery.

System and methods for nerve monitoring

The present invention relates to a system and related methods for performing neurophysiologic assessments during surgical procedures. A method includes the steps of delivering a first transcutaneous, trans-abdominal stimulation signal to a spinal nerve root superior to a surgical target site; and determining a first neuromuscular response data set, based on transmission of said first transcutaneous, trans-abdominal stimulation signal, of a muscle located inferior to said surgical target site.

Systems and methods for performing neurophysiologic monitoring during spine surgery

A system and methods for performing neurophysiologic assessments during surgery, such as assessing the health of the spinal cord via at least one of MEP and SSEP monitoring and assessing bone integrity, nerve proximity, neuromuscular pathway, and nerve pathology during spine surgery.

System and methods for performing neurophysiologic assessments during spine surgery

A method for determining a lowest stimulation threshold current level in a group of channels of a neuromonitoring device. The method includes stimulating tissue at a current level from a predetermined range of current levels as a sequence of pulses delivered at a frequency. The stimulating includes increasing the current level of each pulse in the sequence of pulses from an immediately preceding pulse by a first current increment. The method includes determining that a first evocation pulse from the sequence of pulses evokes a first muscular response. The method includes stimulating the tissue with a second evocation pulse from the sequence of pulses to evoke a second muscular response. The stimulating includes decreasing the frequency of the delivery of each pulse in the sequence of pulses and increasing the current level of each pulse in the sequence of pulses from the immediately preceding pulse by a second current increment. The method includes determining that the second evocation pulse from the sequence of pulses evokes the second muscular response.

Systems, methods, and devices for detecting the threshold of nerve-muscle response using variable frequency of stimulation

The present invention relates to a system and methods generally aimed at surgery. More particularly, the present invention is directed at a system and related methods for performing surgical procedures and assessments involving the use of neurophysiology.

Systems and methods for performing neurophysiologic monitoring

A surgical access system including a tissue distraction assembly and a tissue retraction assembly, both of which may be equipped with one or more electrodes for use in detecting the existence of (and optionally the distance and/or direction to) neural structures before, during, and after the establishment of an operative corridor to a surgical target site.

Surgical access system and related methods

A system performs surgical procedures and assessments. The system includes the use of neurophysiology-based monitoring to determine nerve proximity and nerve direction to surgical instruments employed in accessing a surgical target site.

System for determining nerve direction to a surgical instrument
