Abstract
Long bone fractures are common in juvenile cattle, however, cases of fractures occurring in the intrauterine environment during pregnancy are rare. The objective of this report is to present a case of an open consolidated fracture of the metacarpal that occurred in uterus, in a newborn calf, in which the surgical approach used was successful. A 48-hour-old female bovine was treated at the Veterinary Hospital of Paranaense University, who presented a complete, open and poorly consolidated transverse diaphyseal fracture in uterus during the gestational period on clinical and radiographic examination. As a therapeutic approach, open reduction was chosen, with ostectomy followed by stabilization with type IA external skeletal fixator. Four 4mm transcortical pins were positioned proximally and distally to the newly formed fracture line, followed by two more pins in the proximal phalanges region, seeking to stabilize the metacarpophalangeal joint, since flexural deformity of that joint was observed after the realignment of the longitudinal axis of the metacarpal, even after the section of the superficial and deep digital flexor tendons and suspensory ligament. The ESF was removed after 32 days, when radiographic signs of neoproliferation and bone consolidation were observed. In a last evaluation 15 months after the surgical correction, a complete and satisfactory recovery was observed regarding the development and well-being of the animal.
