Abstract:
Sacral insufficiency fractures result in significant morbidity, and percutaneous sacroplasty has emerged as a promising technique for their treatment. We present a technical note regarding our method of treating these fractures using a "single-needle" lateral technique with a combination of conebeam CT and biplane fluoroscopy. We treated 10 patients, in whom the median Visual Analog Scale pain score decreased from 7.0 to 0 (P < .001). We concluded that single-needle sacroplasty is feasible and safe using this technique.

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
