Percutaneous screw fixation of acetabular roof fractures by radiologists under CT and fluoroscopy guidance.

Objective: The aim of this study was to evaluate CT- and fluoroscopy-guided percutaneous screw fixation by radiologists in the management of acetabular roof fractures.

Subjects And Methods: Fifty-two consecutive adult patients with a nondisplaced and isolated acetabular roof fracture were prospectively treated by an interventional radiologist who made a percutaneous screw fixation under CT and fluoroscopy guidance. All these procedures were performed under local anesthesia.

Computed tomography- and fluoroscopy-guided percutaneous screw fixation of low-grade isthmic spondylolisthesis in adults: a new technique.

Objectives: To evaluate the feasibility of computed tomography (CT)- and fluoroscopy-guided percutaneous screw fixation for the treatment of low-grade isthmic spondylolisthesis in adults.

Methods: Ten consecutive adult patients (four men and six women; mean age: 57.1 [range, 44-78 years]) were prospectively treated by percutaneous screw fixation for low-grade (six grade 1 and four grade 2) isthmic spondylolisthesis of L5.
