Development of a dynamic spinal anchorage system for the treatment of Adolescent Idiopathic Scoliosis (A.I.S.) with motion-preserving implants

Abstract (German)

Spinal fusion is the standard treatment for severe cases of Adolescent Idiopathic Scoliosis (A.I.S.), the most common form of spinal deformity during growth. While instrumented fusion achieves a partial correction and prevents further progression of the deformity, it means that the patients suffer from restricted physical activity for a lifetime and mechanical stress transfer to the few spared spinal segments. Motion preserving non-fusion treatment is an attractive alternative to correct the deformity, while maintaining flexibility. The project deals with the development of a finite element model derived from intraoperative measurements from scoliotic patients to design a new dynamic spinal anchoring system to complement a novel growing implant.
