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.
Matinpour M, Zettner N, Neumann K, Bäumer L, Burkovski A.Horses have close interactions with humans and are important as working animals and livestock. In contrast to smaller companion animals like cats and dogs, there is only little information available about their skin microbiome. The objective of this study was to identify and characterize the culturable cutaneous microbiome of healthy horses. Samples were taken from 14 horses from Southern Germany which were randomly enrolled in this study. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) was used as a method to detect the culturable microorganisms of ...
Albanese V, Straticò P, Fischer H, Petrizzi L.Injuries to the distal limb are common in horses. The clinical aspect of the lesions is variable based on the structures that are involved. Synovial structures as well as tendons and/or ligaments may be involved in such injuries, affecting treatment modalities and costs, and prognosis. This retrospective study compares wounds involving synovial structures to wounds without such involvement in terms of treatment duration and costs, and prognosis. Synovial wounds were much more expensive to treat and carried a lower prognosis. Involvement of tendons and/or ligaments in the wounds resulted in mor...
Cantatore F, Marcatili M, Giacchi A, Stephenson R, Withers J.Morel-Lavallée lesions (MLLs) are post-traumatic, closed, degloving injuries observed in humans and cats. Morel-Lavallée lesions have never been reported in horses. An 8-year-old Warmblood gelding used for dressage presented with a large swelling on the craniomedial aspect of the stifle that did not respond to conservative treatment. Ultrasonography revealed a large anechogenic fluid-filled cavity with a well-defined capsule. Standing endoscopic examination revealed separation between the deep crural fascia, vastus medialis muscle and skin. Cytology of the fluid collected demonstrated a lymp...

The ventral pectoral region was aseptically prepared for skin harvest and locally anesthetized. An 8-mm biopsy punch was used to harvest the grafts. The subcutaneous tissue was then...
Durgam S.The mid-metacarpal SDFT, intrasynovial DDFT and suspensory ligament are frequently injured soft tissues in the equine athlete. The mid-metacarpal SDFT exhibits a hierarchical structure and encounters repetitive strains at its functional limit. The intrasynovial DDFT possesses fibrocartilage where opposing bony surfaces to facilitate resistance-free gliding and contains chondrocyte-like cells embedded in a proteoglycan-rich ECM. While suspensory ligament enthesis injuries are common, collagen and non-collagen ECM structure-function specializations at the bone-ligament interface are understudied...
Fletcher KA, Benedetti B, Limon G, Grist A, Padalino B, Hernández-Gil M, Gibson TJ.There has been limited research into the effectiveness of penetrating captive bolt (PCB) for stunning horses () at slaughter. This study observed 100 horses at a commercial abattoir in Mexico, stunned using pneumatic PCB. Animals were assessed at the time of stunning and immediately after for signs of effective/ineffective stunning and shot positioning, with macroscopic gross brain pathology conducted to determine brain trauma. Twenty-five percent (25/100) received more than one shot and 28% (28/100) displayed behavioural signs of ineffective stunning. Of these 28 animals, all had deviations o...

Partusch L, Rutland CS, Martens A, Du Cheyne C, De Spiegelaere W, Michler JK.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). ...

In the past two decades, rapid advances in equine genomics have significantly deepened our understanding of the molecular basis of these traits. The integration of high-throughput sequencing, genome-wide association studies (GWAS), and single-nucleotide polymorphism (SNP) geno...
Puccetti M, Beccati F, Pilati N.Femoral nerve neuropathy causes lameness, a condition clinically characterized by stifle's lack of extension with subsequent diminished lower limb function. This case report describes the ultrasonographic diagnosis of femoral neuropathy secondary to compression caused by myopathy of the iliopsoas muscle of an endurance horse during a competition. Transrectal ultrasonography played a pivotal role in diagnosis of the injury by assessment of the involved structures and monitoring of the healing process throughout the recovery period. The horse achieved complete recovery and successfully returned ...
Morales Yñiguez FJ, Leise BS.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...
Accorroni L, Dini F, Pilati N, Marchegiani A, Bazzano M, Spaterna A, Laus F.Wound management is a fundamental skill for veterinarians, requiring a systematic approach to wound care and a deep understanding of the biological principles underlying healing. Sucralfate, widely known as a mucoprotective agent for gastroduodenal ulcers, has recently shown promising topical effects in human skin lesions by binding and protecting growth factors from proteolytic degradation, thereby enhancing their local availability. This action promotes angiogenesis, chemotaxis and cell proliferation, while reducing oxidative stress and exerting bacteriostatic and bactericidal effects agains...
