A system for global alignment of a spine during spinal surgery is provided. The system comprises nan imaging device, a spatial tracking system, a rod bending device, a mobile hand held ncommunication device configured to calculate one or more cervical parameters based on n5 identification of spinal markers in a preoperative image, where the spinal markers correspond to n(i) cervical vertebrae and (ii) the first thoracic vertebra, and a control unit. The control unit is nconfigured to receive the one or more cervical parameters, receive a planned target value of one nor more spinal parameters, based on the planned target value of the one or more spinal parameters, ndetermine one or more ranges corresponding to a desired correction in at least one of (i) a sagittal n0 alignment and (ii) a coronal alignment of the spine, capture, via the imaging device, one or more nintraoperative fluoroscopy images, measure an intraoperative value of the one or more spinal nparameters according to the one or more captured intraoperative fluoroscopy images, compare the nintraoperative value of the one or more spinal parameters with the planned target value of the nspinal parameters and the one or more cervical parameters, based on the comparison, determine n5 that the intraoperative value of the one or more spinal parameters is within the one or more ranges nand receive, via the spatial tracking system, a measurement of a location of one or more screws, nand calculate an instruction to bend a rod, via the rod bending device, to the location of the one or nmore screws. A system for use during a surgical procedure and a method for assessing global nalignment of a spine during a surgical procedure is also provided. |
