Figures
- Fig 1.
CT images from needle placement in 2 different patients with sacral insufficiency fractures illustrating the possible orientation for the bone biopsy needle(s) in the sacrum.
A, Axial image showing vertical orientation of the bone biopsy needles in a patient with bilateral fractures.
B. Axial image showing an oblique orientation, paralleling the sacroiliac joint of the bone biopsy needle, in a patient with a unilateral fracture.
- Fig 2.
Fluoroscopic spot films taken during the PMMA injection in a 65-year-old woman with bilateral sacral insufficiency fractures.
A, Frontal projection allows for monitoring of extravasation into the sacral foramina.
B, Lateral projection allows for monitoring for any cement extravasation into the soft tissues.

Previous studies of sacroplasty in patients with osteoporotic insufficiency fractures
Needle Placement Cement Injection Complication(s) Clinical Follow-Up Garant et al4 Fluoroscopy under general anesthesia. Chiba needles placed in sacral foramina. Fluoroscopy None reported Ambulatory and pain-free 9 months postprocedure Brook et al1 CT Guidance under general anesthesia in 2 patients. Intermittent CT Premature cement hardening Pain-free and ambulating at 8 and 16 months Pommersheim et al3 Fluoroscopy in 2 patients. CT guidance in 1. Patients under conscious sedation. Fluoroscopy in all Cement extravasation in posterior soft tissues Pain-free at 14 and 16 weeks. One patient lost to follow-up Deen and Nottmeier2 Kyphoplasty with fluoroscopy in 2 patients. Brain LAB in one patient. Fluoroscopy in 2, Brain LAB in 1 None reported Decreased pain and increased function 3, 6, and 9 months after procedure Butler et al7 CT fluoroscopy under conscious sedation in 6 patients. Fluoroscopy in 5, CT in 1 Inadequate cement distribution, venous intravasation, and extension into SI joint 2–8 weeks. Significantly reduced or eliminated pain in 4 patients Note:—SI indicates sacroiliac.
