Technical aspects of CT assisted surgery

For minimally-invasive fracture fixation, three-dimensional imaging is a superior technique for pre-operative diagnosis and planning, intra-operative control of implant placeme approaches include the combination of a mobile computed tomography (CT) unit with a small gantry size and surface markers to assist internal fixation within the hoof¹ , use o surface marker mesh to identify preoperative guidelines for internal fixation of the distal phalanx and the navicular bone^4,7 or control surgical intervention for various other ort reconstructed from a 190° fluoroscopic scan combined with computer-assisted surgery^1,3,6 .

CT assisted surgery in a hybrid operating room combines minimally invasive fracture fixation using lag screw technique and CT control. In such procedures, the horse is put u obtaining a precise pre-operative diagnosis, control the surgical procedure and perform a post-operative evaluation of the repair including appropriate position and length of t procedure include precise 3D control of all steps of the surgical procedure, lack of radiation exposure to personnel, no need for special surgical equipment apart from an aimi systems and suitability for a variety of indications in the anatomical region extending from the hoof to (and including) the carpus/tarsus.

A technical pre-requisite for such a procedure is a CT unit that allows quick scans of a high-quality and has a large bore sliding gantry. In Zurich, we are currently using a mul and 40 rows of detectors. [...]
