Topic:Equine Wounds
Equine wounds refer to any physical injuries that occur on the skin or underlying tissues of horses. These injuries can result from various causes, such as trauma, surgical procedures, or environmental factors. The healing process of equine wounds involves a complex series of physiological events, including inflammation, tissue formation, and remodeling. Factors such as wound location, size, and the horse's overall health can influence the healing process. Effective management of equine wounds often requires an understanding of wound types, healing stages, and potential complications. This page compiles peer-reviewed research studies and scholarly articles that explore the mechanisms, treatment strategies, and outcomes associated with wound healing in horses.

Progressive structural and functional change in horses: a conceptual framework for systemic equine (patho-)physiology. A wide range of locomotor, postural, and behavioral pathophysiology in horses-often grouped under terms such as Topline Syndrome, Myofascial Dysfunction, or Poor Posture Syndrome-lack a coherent systemic explanation. These presentations share reduced performance, stability, and resilience, yet are commonly managed through isolated symptom-focused interventions. To address this gap, we propose progressive structural and functional change (PSF) as a systemic framework describing progressive reorganization processes within the equine body that link fragmented pathological domains into a coherent ...

Collagen composition in equine exuberant granulation tissue reflects tissue immaturity. Exuberant granulation tissue (EGT) is a second intention wound healing disorder. It commonly occurs in the distal limb of horses. EGT causes significant increase in the duration and cost of treatment, potentially leading to the decision not to pursue treatment and euthanize the patient. The underlying pathomechanisms of this fibroproliferative disorder remain unclear, particularly in terms of collagen composition and the association between myofibroblasts and blood vessels. This study investigated the collagen composition in naturally occurring EGT following trimming in 19 horses (EGT group). ...

Cytochrome c oxidase I deep amplicon sequencing for metabarcoding of equine strongyle communities: unexpectedly high Strongylus spp. prevalence in treated horses. Equines are parasitized by complex communities of Strongylidae (Nematoda) comprising multi-species infections. Currently, Cyathostominae are most prevalent, while Strongylus species are only rarely detected. Since eggs and, in most cases, infective larvae cannot be differentiated to species level, except for Strongylus spp., species-specific knowledge of the pathology, epidemiology and ecology of these parasitic nematodes is limited. Reference sequence data for several cyathostomin species are limited or missing. Deep amplicon sequencing of internal transcribed spacer 2 (ITS-2) regions of nema...
Complications in Wound Management. Over 25% of all emergencies are classified as wounds, making them the most common health conditions treated by veterinarians. While equine wounds may heal with minimal intervention, many complications associated with wound management can occur, thereby delaying wound healing and leading to chronic non-healing wounds. Wounds should be closed primarily when possible; however, numerous factors influence the risk of complications. Infection and biofilm production are common causes of delayed wound healing. Other causes of non-healing wounds include the presence of foreign material, sequestrum form...
