Double DCP Fixation for the Spiral Tibial Fracture of a Racehorse.

Abstract

Plate fixation was conducted in a 3 year old male Thoroughbred racehorse (480 kg) for a spiral undisplaced fracture of the tibia. The fracture line spirally occupied approximately twothirds of the bone. The horse was anesthetized with sevoflurane and oxygen and placed in dorsal recumbency. Two dynamic compression plates (DCP) were applied on the craniolateral and cranio-medial sides. Histopathological examination revealed active callus formation and remodeling on the fracture line 180 days after the surgery. Based on these findings, it was concluded that good synostosis was achieved. Therefore, it was suggested that DCP fixation based on the present technique can be applied to adult horses with undisplaced or minimally displaced fractured tibia to prevent their developing a completely displaced fracture.

Fixação interna de fratura de epífise proximal de tíbia em potro

“…Em termos gerais, as fraturas na tíbia têm uma reparação difícil, muitas vezes associada com complicações que contribuem para uma pequena taxa de sucesso (McDUFFEE et al, 1997). Com o advento das placas de compressão dinâmica e técnicas de fixação interna, o prognóstico dessas fraturas tem sido melhor em potros (SASAKI et al, 1998;McDUFFEE et al, 1997;BERTONE, 1994). Essas placas garantem estabilização suficiente, neutralizando as forças compressivas e de angulação, mas não as forças de torção (McDUFFEE et al, 1997;EASTER et al, 1994).…”
