Özet
Background: The aim of this study was to investigate the anthropometry of the posterior superior iliac spine (PSIS) types in the Turkish population and to determine the safe limits of the length and angle of the sacrum by the posterior lumber approach in lumbosacral instrumentation surgery.Material and Method: Sacral regions (left and right pedicle lengths and pedicle angles) and PSIS types of healthy subjects were evaluated using 3D images.Results: A total of 111 patients (58 males and 53 females) were included in the study. The mean age was 46.9 ± 14.8 in males and 44.3 ± 16.4 in females. In men, the right pedicle length was 52.83 mm, the left pedicle length was 53.81 mm, the right pedicle angle was 35.84, the left pedicle angle was 35.13, and the caudal angle was 39.24 degrees. In females, right pedicle length was 48.88 mm, left pedicle length was 49.28 mm, right and left pedicle angle was 35.83, and caudal angle was 39.24 degrees. PSIS type 1 was found to be 58.6%, type 2 32.4% and type 3 9%.Conclusion: Optimal screw lengths, angles and proper screw orientations can be easily and safely operated in posterior stabilization. In this study, morphometric and anthropometric information related to sacral screw orientation were also determined. These data may help to prevent surgical complications by contributing to the surgeon about preoperative anatomical structure in lumbosacral surgery stabilization procedures.
