How to Radiograph the Tuber Coxae of the Ilium in a Standing Horse

1. Introduction
Fractures of the pelvis are uncommon in horses, ranging from 0.9% to 4.4% of all equine lameness cases.^1–4 There are few reports in the literature describing pelvic fractures in the horse. One study reported on 19 cases of pelvic fractures but none involved the tuber coxae.¹  Another report described 100 pelvic fractures in horses, of which only 6 involved the tuber coxae.² An additional study reported on scintigraphic abnormalities of the pelvic region in 128 horses, of which 25 had abnormal radiopharmaceutical uptake (ARU) of the affected tuber coxae; however, only in 6 of these 25 horses was the ARU associated with the primary cause of lameness. Follow-up information was only available on five of the six horses, and only one returned to racing.⁵  The purpose of this study was to determine signalment, history, clinical signs, radiographic, sonographic and scintigraphic abnormalities, treatment, and outcome in horses with fracture of the tuber coxae and to describe a radiographic technique for obtaining a dorsomedial-ventrolateral oblique projection of the tuber coxae portion of the ilium in standing horses.
