ABSTRACT
<p><b>OBJECTIVE</b>To describe the satisfactory intra-iliac paths in Galveston fixation combined with adult human cadaver and radiology study.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>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.</p><p><b>CONCLUSION</b>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.</p>
