Hybrid Construct Versus Pedicle Screw-only System for the Treatment Scoliosis

The placement of pedicular screws in spinal surgery has become the gold standard for scoliosis treatment. However, the use of sublaminar bands (SBs) on the apex of the curvature in idiopathic scoliosis (AIS) lowers the risk of neurological complications related to incorrect implementation of transpedicular screws into dysplastic pedicles without a cancellous channel. The latest research does not define a set of anatomical guidelines for applying SBs, nor does it use a dedicated classification system related to the structure of pedicles. The aim of this study was to assess the safety of the method and the correction attained through hypoplastic/aplastic pedicles when applying a hybrid instrumentation system to patients suffering from AIS Lenke type 1. Methods: Twenty patients were involved in a prospective, single-center, non-randomized case series study. The patients were assigned to the group "SCREWS" or "HYBRID" where SBs were used.
