Adolescent Idiopathic Scoliosis (AIS) is a complex three-dimensional deformity of the spine characterized by abnormal development in the sagittal, coronal and axial planes. Spinal fusion using pedicle screw instrumentation is a widely used method for surgical correction in severe AIS curves. It is essential to understand the altered pedicle anatomy in order to accurately select the appropriate starting point, screw size and screw trajectory, thus reducing the risk of pedicle screw misplacement which may cause neurological, vascular or visceral injury. This study measured and analysed the complex pedicle anatomy in the AIS spine to provide important clinical information for spinal surgeons. This study found a statistically significant asymmetry in the pedicle morphometry of AIS patients. Knowledge of this anatomical variation is critical for scoliosis correction surgery using pedicle screws.

Impact and interest:

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
