Sagittal fracture of the proximal phalanx in a horse complicated during induction of anesthesia by complete fragmentation of the bone: a case report

Abstract

ABSTRACT:The case of a sagittal fracture P1 in the pelvic limb that was complicated during the flexion of the limb by lying down at the beginning of anesthesia, by complete fragmentation of bone is presented. Fragments were not seriously dislocated, but there was no stabile strut between the metatarsophalangeal and proximal interphalangeal joints. The immediate fixation with lag screws and cast application resulted in complete primary healing and a successful return to training for flat racing. The real danger of complete fragmentation during the induction of anesthesia is documented in this case. For the prevention of such a complication it is recommended to put the horse into recumbence with the affected limb casted. The successful treatment of the comminuted P1 fracture by application of lag screws in the absence of a strut between both joints is described.

Ex vivo comparison of standing and recumbent repair of incomplete parasagittal fractures of the first phalanx in horses

“…Equine standing fracture repair represents an attractive treatment modality primarily because of the risk of anaesthetic induction and recovery related morbidities 17,18 and may facilitate more cost-effective case management. Incomplete parasagittal P1 fractures provide an ideal opportunity to perform standing repairs because few implants are required and fracture gap instability is not a concern.…”
