Intraoperative 3D Tomosynthesis of the Elbow in a Simulated Prone-Position Setup: A Cadaveric Study

Background/Objectives: Fractures of the distal humerus and olecranon often require surgical intervention due to their complexity and intra-articular fracture pattern. Precise implant positioning and articular surface reconstruction are crucial for optimal outcomes. Intraoperative 3D imaging offers advantages over 2D fluoroscopy by providing enhanced visualization of fracture reduction and implant alignment. However, limited space in the prone position restricts the use of standard 3D imaging with complete orbital rotation. This cadaver study investigates the feasibility and intra-articular screw detection performance of intraoperative 3D tomosynthesis with reduced orbital rotation at the elbow.
