Life wins! Dr Chalopin from CHU de Nantes performed a bone tumor resection while preserving the joint of this 3 year old boy! Our designer Alice Rouvez, with the help of Laurent Paul, was able to create a custom-made cutting guide based on the MRI scans.
The purpose of the operation was to cut the bone right below the femur’s growth plate, which was acting as a wall between the tumor and the joint.
Therefore, the cutting guide had to be placed below this growth plate, on the cartilage, which is invisible on the CT. Alice manually segmented each slice of the MRI to be able to reconstruct in 3D the cartilage to use its surface to place the guide. The rest was beautifully managed by Dr Chalopin and the post-operative analysis showed a R0 resection, meaning that the full tumor was resected.
Big success for us!
