Comparative StudyComparison of 3D C-arm fluoroscopy and 3D image-guided navigation for minimally invasive pelvic surgery.
This study aims to compare the efficacy and accuracy of percutaneous screw fixation using three-dimensional [Formula: see text] navigation and conventional C-arm fluoroscopy in pelvic fracture surgery. ⋯ Percutaneous screw fixation using the [Formula: see text] navigational system minimizes the fluoroscope exposure and screw insertion time, while improving screw insertion accuracy. Moreover, the [Formula: see text] navigational system provided a reliable method for fluoroscopy imaging in pelvic fractures.

Haptic computer-assisted patient-specific preoperative planning for orthopedic fractures surgery.
The aim of orthopedic trauma surgery is to restore the anatomy and function of displaced bone fragments to support osteosynthesis. For complex cases, including pelvic bone and multi-fragment femoral neck and distal radius fractures, preoperative planning with a CT scan is indicated. The planning consists of (1) fracture reduction-determining the locations and anatomical sites of origin of the fractured bone fragments and (2) fracture fixation-selecting and placing fixation screws and plates. The current bone fragment manipulation, hardware selection, and positioning processes based on 2D slices and a computer mouse are time-consuming and require a technician. ⋯ 3D haptic-based patient-specific preoperative planning of orthopedic fracture surgery from CT scans is useful and accurate and may have significant advantages for evaluating and planning complex fractures surgery.
