[Anatomic study of paths for transiliac screws in Galveston fixation].
OBJECTIVE
To describe the satisfactory intra-iliac paths in Galveston fixation combined with adult human cadaver and radiology study.


METHODS
Five adult cadavers with 10 hemisected pelvises were harvested. Parallelly to the Chiotic line, the bone every other 5 mm till the superior rim of the acetabulum (SRA) observing the morphologic characteristics of each cross-sections of the iliac columns was cut. Fifty consecutive and randomly selected patients were measured using three-dimensional computed tomographic reformations. Three paths' valid bony canal lengths (LVBC), contractions' inner widths and positions were evaluated.


RESULTS
The Path A with the longest LVBC (137 +/- 8) mm in male, (130 +/- 11) mm in female was the most satisfactory intra-iliac path according to both adult cadaver and radiographic measurement Path A and B allowed placement of 100 mm and 8 mm implants in male, 80 mm and 6 to 7 mm implants in female patients.


CONCLUSIONS
The Path A, passing from the Click point towards the bottom of the anterior inferior iliac spine provides a longer and potentially safer anchor site compared with the traditional path.
