“…Complications of surgical treatment of third metacarpal fractures can be rather common (19 %) and involve local problems like fragmentation of drill bits, osteomyelitis, disturbed fracture union, catastrophic failure of the cannon bone or local infections as well as more generalised complications like laminitis and colitis (McClure et al 1998, Lescun et al 2007). Furthermore, recurrence of the fracture at the same site does occur (Cervantes et al 1992).…”

Summary: Different types and locations of fractures of the third metacarpal bone have been discussed for decades, especially in regard to treatment and prognosis. There is lack of documentation of frontal plane third metacarpal fractures diagnosed by MRI within the extensive previous literature. The present case report describes an incomplete frontal plane third metacarpal fracture in a dressage horse. The A 6 year-old Hanoverian mare was suddenly lame during side passes within a dressage contest. Physical examination revealed a grade 3/5 lameness of the left forelimb. When standing the horse showed a tendency to leg rest. A discrete oedematous swelling from the medioproximal metacarpus to the middle third of the flexor tendons was palpable. Rotation of the phalanx resulted in a mild pain response. Initially a basic set of x-ray images was carried out, which did not show an evident fractureline. To further evaluate the cause of local swelling and lameness a standing MRI examination was carried out with a 0.27 Tesla Hallmarq EQ2 dedicated equine MRI system. In consequence, an incomplete frontal plane fracture of the third metacarpal bone was confirmed. The images depict typical features of acute fractures in MR studies. Angle adapted x-ray images were taken and the fracture line initially obscured by the splint bones became visible. No diagnostic block was performed due to the risk to worsen the incomplete fracture. Conservative management was chosen. During the first four weeks immobilisation was applied and exercise was restricted to box rest for another four weeks. During that time the mare was re-evaluated regarding to lameness in the walk, by MRI and by x-ray images. In the present case conservative management led to complete recovery. The last recheck in the stable took place after 46 weeks by the referring veterinarian. Until that time no signs of secondary osteoarthritis had occurred in follow-up radiographs taken by the referring veterinarian.

Diaphyseal fractures of the III metacarpal bone represent 22% of all fractures of the long bones in horses. Treatment of such cases is difficult. The most popular solution used in these types of fractures is two plates applied directly to the bone surface, but they are not applicable on contaminated and infected fractures.External fixators are quite commonly used in human medicine, although in veterinary practice there is no typical stabilizer designed for the treatment of diaphyseal fractures of the III metacarpal bone so far. In this study, an external semicircular fixator of our own design was used and in vitro strength tests were conducted to determine the maximum force which would lead to the destruction of non-fractured bone and fractured bone treated with the stabilizer.On the basis of the strength tests, we can conclude that the stabilizer can be strong enough to allow the horse to stand up after surgery. It also has many favorable features which make it easy to assemble and to take care of a wound, while being safe enough for the animal at the same time.

“…Em equinos, são utilizados para tratar fraturas de McIII, MtIII, multifragmentares, expostas ou com extensa lesão de tecidos moles (LESCUN et al, 2007 O plasma rico em plaquetas (PRP) concentra uma grande variedade de fatores de crescimento e aumenta a taxa de proliferação de vários tipos celulares, além de desempenhar um papel importante na síntese e remodelamento do tecido de reparação (GRIFFIN et al, 2009;CARMONA et al, 2011). Assim, o objetivo desta nota é relatar o caso de uma potra com fratura diafisária multifragmentar em cunha de MtIII, tratada com pinos transcorticais e gesso, associados à injeção local de PRP.…”

“…Nas fraturas completas do Mc/MtIII em equinos jovens, recomenda-se o tratamento cirúrgico, com redução aberta e imobilização do foco com duas placas de compressão dinâmica que visam à reconstrução anatômica do osso (BISCHOFBERGER et al, 2009;LEVINE & RICHARDSON,2007). Porém, pela característica multifragmentar da fratura, optou-se pela imobilização com pinos transversais, sem a abordagem cirúrgica do foco, visando a minimizar lesões vasculares e aos tecidos moles adjacentes e diminuir o risco de contaminação bacteriana com consequente colonização do implante (LESCUN et al, 2007).…”
