Objective:
To compare the efficacy of 2D fluoroscopy with intraoperative computed tomography (CT) in detecting intra-articular screws that extend beyond the dorsal cortex in distal radius fractures.
Methods:
Prospective study of 10 patients undergoing osteosynthesis of distal radius fractures, evaluating the accuracy of 2D fluoroscopy and intraoperative CT.
Results:
2D fluoroscopy did not identify inadequate positioning, while intraoperative CT detected 20% of intra-articular screws and 60% of screws going beyond the dorsal cortex.
Conclusion:
Intraoperative CT is more effective in detecting inadequate positioning of the synthesis material and may prevent future complications. Level of Evidence III; Prospective d comparative study e.

The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
