Pelvis/femur modeling

Hip Analysis Suite

Automated diagnostic and preoperative software

Virginia Commonwealth University researchers have developed an automated software package that provides 3D models and morphometric analysis of the femur and pelvis based off of a patient’s CT scan. Current methods for preoperative imaging rely solely on 2D imaging, and can lead to differences between model and patients. Doctors use these models to diagnose ailments as well as to aid in the hip replacement surgery operation. Using this software package, doctors or surgeons can build more accurate pre-operative hip models to increase hip replacement surgery success rates. In addition, the system can provide relevant data for diagnosis of hip conditions.

The technology

Patients undergoing treatment for hip disease or replacements generally depend on 2-Dimensional models to get accurate treatment. This process can lead to human error by the technician or surgeon and reduce likelihood of healthy patient outcome. The guidelines are based on published research and help therapists in making treatment decisions. VCU’s novel algorithm uses hundreds of landmarks to accurately estimate and model the femur and pelvis of each individual patient.

Hip angle and size measurements are critical to hip replacement surgery success, and improper placement leads to abnormal biomechanical function. In addition, many patients needing hip surgeries have abnormal orientations. Using this novel application can lead to the reduction in inadequate estimations; provide clearer and safer diagnosis of hip injuries or diseases. The application of this program could lead to increased success rates and reduce healthcare costs overall for hip replacement surgeries.

VCU is seeking market insight on commercialization of this novel data collection system. We welcome interest from potential partners and licensees.
