Gravity line based surgical planning for spinal deformity corrections
This project is about the implementation of an algorithm based on the patient's gravity line to help plan spinal deformity corrections.

Spinal deformities are a common phenomenon, especially in the elderly. When conservative treatment of symptomatic deformities is unsuccessful, surgical intervention becomes necessary. These surgeries typically aim to fuse multiple levels of the thoracic and lumbar spine with a posterior approach using metal screw-rod systems to mechanically correct the deformity. Per year approximately 1.2 million deformity corrections are performed.
Despite the large number of operations performed, there is no ideal way to plan such a surgical procedure. Since the patient has already suffered a pathological deformation of his spine, the desired "ideal posture" can only be estimated in the surgical planning. This planning is usually done with the help of EOS scans, which provide an overview of the alignment of the spine. One problem in planning such a procedure is that while geometric planning can be done very easily, it is not clear what the posture of the remaining part of the spine will be. In this project an idea of how to calculate and simulate this functional correction shall be implemented.

- Conduct a small clinical study with patients to collect data. A force plate will be used to identify the patient's gravity line when performing EOS.
- Programming an algorithm that can identify the mass distribution of the patient based on the X-ray density of the EOS.
- Programming and implementation of the proposed algorithm in Matlab.
