The importance of curve severity, type and instrumentation strategy in the surgical correction of adolescent idiopathic scoliosis: an in silico clinical trial on 64 cases

Abstract Adolescent idiopathic scoliosis is a three-dimensional deformity of the spine which frequently corrected with implantation instrumentation generally good or excellent clinical results; mechanical post-operative complications such as implant loosening and breakage are however relatively frequent. The rate associated lack consensus about surgical decision-making process; choices length, anchoring implants degree correction indeed mostly based on personal views previous experience surgeon. In this work, we performed an in silico trial large number subjects order to clarify factors have highest importance determining risk by quantitatively analysing stresses loads after maneuvers. results simulations highlighted fundamental role curve severity, also its aspect, strategy, whereas length fixation had lower importance.
