“…More recently, Abul-Kasim et al found a 32% rate of screw loosening in patients operated for AIS in a 2-years follow-up study [9]; Uehara and colleagues reported similar figures, and a tendency toward higher loosening rates for malpositioned screws [10]. Mechanical complications associated with the posterior rods are also relatively common; Flynn and coworkers observed radiographic adverse events, including rod breakage, loss of correction as well as proximal screw pull-out in 6.8% of patients treated with posterior instrumentation for Lenke type 1 AIS [11].…”

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

“…In addition, Weiss and Goodall described a varied but high rate of post-operative complications such as mechanical failure of the instrumentation, pseudoarthrosis, screw loosening, loss of correction, and several others [8][9][10][11] . Delayed complications associated with the posterior rods are relatively common; Flynn et al observed radiographic adverse events, including rod breakage, loss of correction as well as proximal screw pull-out in 6.8% of patients treated with posterior instrumentation for Lenke type 1 AIS 12 .…”
