“…Nuclear scintigraphy is a sensitive diagnostic tool in cases associated with trauma, especially when radiography is not possible or practical. 3 Delaying the scintigraphic examination for at least 10 days minimizes false-negative results. Decreased radiopharmaceutical uptake at fracture sites may be detected when nuclear scintigraphy is performed in the first few days after injury because of limited modeling (osteoblastic) activity.…”

“…2 This imaging approach has many perceived practical concerns associated with anesthetizing and recovering severely lame horses that may have fractures susceptible to further propagation during anesthetic induction, patient movement, and recovery. 3 Ultrasonography and nuclear scintigraphy are useful for detecting injuries of the pelvis in horses. [3][4][5] Ultrasonographic findings that support a diagnosis of pelvic fracture include an irregular cortical contour (roughened surface and a step or gap in the bone surface) and evidence of soft tissue damage (fluid accumulation, disrupted muscles, and increased soft tissue thickness).…”

“…4 Limitations associated with use of ultrasonography to diagnosis pelvic fractures include the inability to visualize all bony surfaces and the unlikely identification of minimal or nondisplaced fractures. 3 Comparative images from the normal contralateral side of the pelvis can be useful for image interpretation. In the horse reported here, ultrasonography provided definitive evidence of bone and soft tissue trauma compatible with a fracture in the region of interest and permitted early institution of proper care and treatment.…”

HistoryA 12-year-old Thoroughbred gelding was referred for evaluation of grade 4/5 lameness 1 of the right hind limb of 4 hours' duration. During exercise under saddle, the horse reared and fell backwards, initially landing on the right side of the pelvis and right hind limb. On physical examination, abrasions were noted on the proximal interphalangeal joint in the right hind limb proximal to the coronary band. Soft tissue swelling was detected, and signs of pain were elicited during palpation of the right semimembranosus, semitendinosus, and biceps femoris muscles, and right ischiatic tuber. During palpation per rectum, a mass (7 cm in diameter) was detected pararectally at the dorsal aspect of the pelvic canal approximately 20 cm from the anus. A transrectal ultrasound-guided fineneedle aspirate of the mass was obtained; the cytologic diagnosis was melanoma. The mass was considered an incidental finding. Standing oblique radiographs of the right and left ischiatic tubers were obtained; however, results were not diagnostic. Radiography during general anesthesia was not considered appropriate for this horse because of concerns that recovery from anesthesia may cause additional trauma to the affected limb. Except for the melanoma, no abnormalities were detected during transrectal ultrasonography of the pelvic canal. Transcutaneous ultrasonography of the right and left ischiatic tubers and regional muscles was performed (Figure 1).Determine whether additional imaging studies are required, or make your diagnosis from Figure 1-then turn the page. * * Figure 1-Cross-sectional ultrasonographic images of the right (A) and left (B) ischiatic tubers in a 12-year-old horse evaluated for a grade 4/5 lameness of the right hind limb. Images were obtained at the center of the prominence with a 4.5-MHz microconvex transducer at a scanning depth of 164 mm. Lateral is to the left of the images and medial is to the right.

“…Fractures of the pelvic girdle are common and potentially life threatening training and racing injuries. The vast majority of fractures of the pelvis that occur during racing or training are stress related injuries and as such have predilection sites Pilsworth 2003). Occasionally, fractures of the pelvic girdle will result from falls or other on course trauma such as injury in starting stalls.…”

Summary In consideration of first aid of appendicular fractures in the horse, the literature is inconsistent and in some cases wrong or misleading. This in large part is due to misunderstanding of fracture mechanics and this paper aims to give a contemporary review of the subject. It is particularly relevant for fractures that occur on the racecourse or in horses in training which, due to their aetiopathogenesis, have substantial site and configuration commonality. However, the techniques discussed are frequently also applicable to non‐racing injuries. Clinical features are important in assessing horses on the racecourse when imaging techniques are limited. This paper highlights these in order to guide decision making.
