Title
Infrared Image-Guidance For Intraoperative Assessment Of Limb Length Discrepancy During Total Hip Arthroplasty Procedures
Abstract
During total hip arthroplasty (THA) procedures, orthopedic surgeons rely on visual and tactile cues to minimize the risk of a limb length discrepancy (LLD) arising from improper implant placement and selection. This paper outlines a novel application of a commercial infrared (IR) motion controller, Leap Motion, to function as an optical tracker of LLD. Additionally, a custom benchtop testing model was used to evaluate accuracy and precision of this commercial IR motion controller against a custom-built IR stereo vision camera. This paper includes a discussion of the algorithms and infrared technology used to image and localize points. The novel design discussed in this paper has clinical applications for a custom-built IR stereo vision setup that will be positioned above the incision site during a THA procedure. Accompanying this solution concept is a fiducial with IR-visible landmarks for quick and accurate point selection and a software algorithm that measures changes between pre- and post-operative leg length.
