Our study provides comprehensive anatomical analysis of the IVF at the cervical vertebral levels C5/C6 and...
Hoist failure during recovery transfer in an anaesthetised horse: a near miss analysed through a Safety-II lens. A 660 kg, 11-year-old Irish Sport Horse gelding underwent general anaesthesia for an out-of-hours emergency exploratory laparotomy. After approximately 5 hours of anaesthesia, transfer to the recovery box began, using a ceiling-mounted hoist. As the horse crossed the theatre-recovery interface, the hoist failed due to mechanical disengagement. This resulted in loss of electrical power, leaving the anaesthetised horse suspended approximately 150 cm above the floor for approximately 10 minutes. The horse could not be advanced, reversed, or lowered using standard controls. Activity was paused, an...

A point-based laminitis risk scoring system and machine learning framework for prediction of laminitis in horses. Laminitis is a painful and potentially life-threatening inflammatory condition of the equine hoof, and its detection remains a major challenge in veterinary practice. Although several risk factors have been reported, the prediction of the onset of laminitis in a subclinical stage using routine clinical data is still limited. This study aims to address this gap by developing an interpretable machine learning (ML) framework for the prediction of the risk of laminitis in horses. A point-based risk scoring system was first constructed using multivariate logistic regression to quantify the contribu...
Straight sesamoidean ligament desmopathy commonly occurs with proximal interphalangeal joint osteoarthritis. Proximal interphalangeal joint osteoarthritis (PIPJ OA) is a common cause of poor performance in the equine athlete; however, the supporting soft tissue structures surrounding the joint are seldom evaluated. Straight sesamoidean ligament injuries have been previously hypothesised to be concomitant with PIPJ OA; however, the frequency of these lesions coinciding with PIPJ OA has not been fully investigated.

Improving Inclusivity in the Curriculum via the Introduction of an Equine Industry-Specific Language eGlossary. The equine veterinary profession is frequently considered inaccessible to veterinary students who have had limited exposure to the equine industry. One of the perceived reasons for this inaccessibility is the use of what is often coined "horsey" language within the industry. If a student has limited experience of the equine industry, there is a potential language barrier to teaching, which may result in poor engagement with equine teaching and placements. The aim of this Teaching Tip is to describe the development and evaluation of a new teaching resource designed to demystify equine industry-...
Comparative clinical and thermographic responses to dexamethasone and saline solution mesotherapy in horses with spinal disorders. Back pain and spinal dysfunction in horses are multifactorial conditions frequently associated with musculoskeletal alterations that may impair mobility, performance, and welfare. Mesotherapy has emerged as a minimally invasive adjunctive approach for managing musculoskeletal disorders; however, comparative clinical responses to different intradermal protocols in equine spinal conditions remain insufficiently investigated. The present study aims to compare the clinical and thermographic responses of two mesotherapy protocols in horses diagnosed with cervical or thoracolumbar spinal disorders. ...
Umbilical vein marsupialization in foals-short literature review. Umbilical remnant infections are common in neonatal foals and may involve one or more umbilical structures. Diagnosis relies on thorough clinical examination, ultrasonography, and hematologic evaluation. Standard care includes broad-spectrum antibiotics, with surgical resection if conservative therapy fails. Omphalophlebitis may extend to the liver, prompting consideration of umbilical vein marsupialization. Surgery is performed in dorsal recumbency with a fusiform incision around the umbilicus. The umbilical arteries and urachus are ligated and transected, with partial cystectomy when indicat...
