OFIX MIS App

The OFIX MIS App is a mobile software application designed to assist healthcare professionals in orthopedic surgery planning by enabling the viewing, storing, and measuring of 2D images captured via a mobile phone camera. Its primary methodology involves analyzing these images to determine appropriate rod lengths for Orthofix pedicle screw spinal systems, thereby supplementing traditional caliper measurements and providing corresponding product information.

The OFIX MIS App is a software application designed for healthcare professionals to assist in planning orthopedic surgeries. Its core functions include enabling users to view, store, and measure medical images, specifically for the purpose of planning surgical procedures that involve the placement of implants, requiring clinical judgment and experience from the healthcare provider for its proper and effective utilization. Functioning as a novel mobile phone-based solution, the OFIX MIS App is intended to supplement the traditional use of calipers, particularly in selecting appropriate rod lengths for pedicle screw type spinal systems used in immobilization and stabilization. The app leverages the mobile phone's camera to capture 2D images relevant to spinal implant procedures, then processes these images by measuring the difference between known Orthofix pedicle screw diameters to provide feedback on suitable rod lengths and the corresponding Orthofix product numbers. Non-clinical software verification, validation, and usability testing demonstrated the app's accuracy and usability as intended.
