Therapeutic technology

Children with uneven lower limbs usually receive cumbersome and complex treatment to gradually lengthen their legs with external fixators. The Aequalis project aims to develop a new generation of implantable medical device that improves and accelerates long bone elongation in children and eliminates the need for cumbersome external fixators.

Achievements and impact

Within three years, the team developed an innovative prototype of an internal fixative that does not affect growth plates. This technology is currently being tested in the sheep model. For young patients, it offers the hope of a treatment to improve their quality of life without the need for cumbersome and problematic external fixators.
