LOADPRO™ Intraoperative Rod Strain Sensor
Large spinal segment correction procedures (Scheuermann Kyphosis, thoracolumbar hyperkyphosis and kyphotic burst fracture reduction), require strategic pedicle screw placement and symmetrical spinal rod strain balancing for obtaining mechanical correction and maintaining rigid fixation for an optimum mechanical and biological environment such that fusion may occur (Kanayama, 1997). The consequences of semi-rigid fixation include incomplete biological fusion, altered construct load, pedicle screw loosening or fracture and rod breakage (Kanayama, 1997; Tsirikos, 2011; Jain, 2014). The LOADPRO™ Intraoperative Rod Strain Sensor is a passively powered (external inductive coupling), single use, disposable, orthopaedic assessment aid, for the intra-operative measurement of spinal rod strain values. Bilaterally placed LOADPRO™ Intraoperative Rod Strain Sensors measure spinal rod strain and simultaneously communicates left versus right rod strain asymmetry to an external reader during corrective surgical maneuvers.

About Intellirod Spine
Intellirod Spine™ (formerly OrthoData Inc.) was founded by renowned spine surgeon Rolando M. Puno, M.D. and professors from the University of Louisville. The company is developing a wireless implantable microelectronic spinal rod strain sensor. This innovative strain monitoring system will allow spine surgeons to objectively assess the strain on implanted spinal fusion rods.
The difficulty in detecting bone growth
after spine fusion is a known challenge.
