Synovial involvement following solar foot penetration has a guarded prognosis for survival to discharge and a poor prognosis for return to pre-injury athletic function. Penetration of the central sulcus of the frog and distal phalanx involvement are associated with euthanasia during hospitalisation. Delayed referral and hospitalisation are associated with both euthanasia and failure to return to pre-injury athletic function. Breed and more than one surgery are associated with failure to return to pre-injury athletic function. These data may assist veterinary surgeons and owners to make evidence-based decisions when managing cases with synovial involvement following solar foot penetration.

Word Count: 4638 5 2 Summary 6Reasons for performing study: The pattern of long-term survival and specific factors 7 associated with long-term survival have not previously been evaluated in horses with a 8 strangulating large colon volvulus (LCV). 9Objectives: The aims of this study were to provide data on the long-term survival of horses 10 with LCV and to identify pre-, intra-and post-operative variables associated with survival. Conclusions: Survival time in horses with a LCV was associated with pre-operative PCV, 27 serosal colour, heart rate at 48 hours post-operatively, and colic during post-operative 28 hospitalisation.

Summary 6Reasons for performing study: Risk factors for large colon volvulus (LCV) in the horse have 7 not been previously reported. Knowledge of these risk factors may allow the introduction of 8 measures that could be taken to minimise the incidence of LCV. 9Objectives: To investigate risk factors for LCV in the horse. 10Methods: A prospective, multi-centre, un-matched case-control study was conducted over a and to provide evidence-based advice to owners of these horses. 29
