Fractures of lumbo-sacral junction involving bilateral sacral wings are rare. Posterior lumbo-sacral fixation does not always provide with sufficient stability in such cases. Various augmentation techniques including divergent sacral ala screws, S2 pedicle screws and Galveston rods have been reported to improve lumbo-sacral stabilization. Galveston technique using iliac bones would be the best surgical approach especially in patients with bilateral comminuted sacral fractures. However, original Galveston surgery is technically demanding and bending rods into the appropriate alignment is time consuming. We present a patient with unstable lumbo-sacral junction fractures and comminuted U-shaped sacral fractures treated by lumbo-sacro-pelvic fixation using iliac screws and discuss about the advantages of the iliac screws over the rod system of Galveston technique.

Lumbo-sacral junction is a transition lone between the mobile lumbar spine and immobile pelvis. Lumbosacral junction has been considered to be the most troublesome portion of the spine to be fused because of the difference in anatomical and biomechanical factors between spine and pelvis. A metastatic sacral tumor in a 57-year-old man was resected, followed by unilateral lumbo-iliac fixation across lumbosacral junction using modified Galveston technique. Rigid fixation was successfully achieved. Detailed anatomy and surgical techniques are presented.
