CROSSTALK: COMBINING DIAGNOSTIC APPROACHES FOR CASE SUCCESS
Fig. 6. A, Transverse CT image of the proximal metatarsus at the origin of the suspensory ligament. There is a marked enthesop- athy with new bone formation (white arrows) and plantar cortical resorption at the origin of the suspensory ligament. B, 3D recon- struction showing enthesopathy with new bone formation and bony irregularity (black arrows). C, Proximal suspensory ligament desmopathy (arrows) noted on CE-CT of the metacarpus.
Fig. 7. A, Left to right lateral (left), right ventral-left dorsal (RV-LD) oblique (middle), and left ventral-right dorsal (LV-RD) oblique (right) radiographs of a horse suspected of having intervertebral foraminal stenosis due to periods of inability to raise his head and a hopping left front limb lameness that could not be blocked out. Osteoarthritis with enlargement of the articular process joint can be seen at C6-7. B, Transverse and sagittal CT images obtained from a standing CT scan show definitive evidence of foraminal stenosis at C6-7 (arrows). The left is more severely affected.
when inserting screws through the hoof for the treat- ment of P3 or navicular bone fractures where the hoof prevents accurate measurement of the drilled hole. 3D reconstructions can be especially helpful when preparing for treatment of comminuted fractures; however, they should always be examined in conjunc- tion withMPR images (Fig. 11). As mentioned, complex and comminuted fractures

lend themselves well to preoperative CT imaging. CT provides an in depth understanding of fracture planes and can be used to plan implant placement. This is particularly helpful in comminuted P1 and P2 fractures and complex carpal fractures. Preoperative CT is also very useful in horses with more simple
