Coffin Bone Fracture and Mild DDFT Lesion<\/h2>\n\n\n\n
<\/div>\n\n\n\n

Patient Information<\/h4>\n\n\n\n

This case study is kindly provided by Dr. Chris Bell, owner of Elders Equine Clinic<\/a>, Manitoba. The case details a 12-year-old Quarter Horse gelding, imaged with Hallmarq’s Standing Equine MRI and Vision CT. With combination scanning using both modalities, a coffin bone fracture\/fissure (type 2 fracture) and mild DDFT lesion in the medial lobe in the mid-pastern to about the top of the navicular bone margin was diagnosed. <\/p>\n\n\n\n

Clinical History<\/h4>\n\n\n\n

The gelding has had a right front lameness, grade 3\/5, for approximately 6 weeks. Blocks to abaxial with partial block to PD. Switches to left front lameness grade 1-2\/5. <\/p>\n\n\n\n

Radiographs show navicular sclerosis, some distal margin surface irregularities, and vascular channel\/synovial evaginations but no obvious issue on the bone\/joint for the lameness. The referring clinician took X-rays.<\/p>\n<\/div>\n<\/div>\n\n\n\n

MRI was initiated and, during the exam, something in the coffin bone and the tissues surrounding the wing of the coffin bone and DDFT was apparent. This prompted a call to the owner and the suggestion that the horse be moved straight to CT following MRI.<\/p>\n\n\n\n

The fissure\/fracture in the wing off the coffin bone was not appreciated or visible on the plain radiographs. However, it showed up clearly on the CT with MRI for supporting comparison of the extent of the fracture. The client appreciated the CT image of the fracture the best as a full 3D reconstruction was done on the premises and made available to her immediately. <\/p>\n\n\n\n

\u201cThis was a very neat case. I\u2019m glad the client decided to proceed to CT\/MR, I don\u2019t think we would have appreciated the extent of the fracture and soft tissue injuries without both modalities available.\u201d <\/p>Dr. Chris Bell BSc, DVM, MVetSc, Board Certified Equine Surgeon (DACVS), Equine Surgery, Lameness and Sports Medicine, Elders Equine Veterinary Service<\/cite><\/blockquote>\n\n\n\n
