Cadaver studies involving horses provide valuable insights into equine anatomy, pathology, and surgical techniques. These studies involve the examination and dissection of deceased horses to better understand the structure and function of various bodily systems. By utilizing cadavers, researchers and veterinary students can gain hands-on experience in identifying anatomical features, understanding disease processes, and refining surgical skills without the ethical concerns associated with live animal experimentation. Cadaver studies also contribute to the development of new diagnostic and therapeutic approaches by allowing for detailed exploration of equine anatomy and pathology. This page compiles peer-reviewed research studies and scholarly articles that explore the methodologies, findings, and applications of cadaver studies in equine science.
Updike SJ.Equine tarsocrural collateral ligaments (CL) were dissected grossly. The areas of attachment and fiber arrangements were described for the long lateral CL, long medial CL, 3 short lateral CL, and 3 short medial CL. Sequential cutting of CL in any order indicated that the short medial CL were responsible for the snap-joint phenomenon observed at the equine tarsocrural joint.
Strömberg B, Tufvesson G.Four autologous tendon grafting techniques, bipedicle, pedicle and free grafts of the deep digital flexor tendon and free grafts from the lateral digital extensor tendon were described. The vascularization and remodelling of the transplant and the reactions in the donor, as well as the recipient tendon, were studied by means of microangiographic and histochemical methods. The results indicated that regardless of the technique used the grafts were revascularized and replaced by a highly orientated and organized tendon. The use of free grafts may therefore be worthwhile in treatment of severe te...
Webbon PM.The results of a survey are presented in which 589 limbs from 206 horses were dissected. In174 of the limbs lesions were found in either the superficial (131) or deep (43) digital flexor tendons. Changes occurring with age were also recorded. The sites of the abnormalities and their macroscopical appearance are described and the value of the results is considered in relation to the diagnosis and the treatment of clinical lesions.
Rankin JS, Diesem CD.The hindlimbs of 3 ponies and 3 horses were dissected. The hip joint capsule was found to receive articular nerve fibers from the femoral, obturator, cranial gluteal, and sciatic nerves. The nerve fibers were distributed to the fibrous joint capsule and associated capsular ligaments. The stifle joint capsule was found to receive articular branches from the femoral, saphenous, obturator, common peroneal, and tibial nerves. The fibers terminated in the joint capsule, fat pad, patellar and collateral ligaments, and the internally situated meniscal and cruciate ligaments.
Hagenbach M, Bierau J, Rott P, Röcken M, Staszyk C.The aim of this study was to display clinically relevant anatomical structures of the carpal region in healthy horses with the help of cone beam computed tomography (CBCT).Twenty-eight forelimbs from 15 adult horses without orthopedic diseases were examined. Following native CBCT examination a mixture of hyperattenuating contrast medium with blue epoxy resin dye was injected in the antebrachiocarpal joint and middle carpal joint and contrast-enhanced CBCT scans were also acquired. Subsequently, the limbs were frozen and sawed in different planes corresponding to selected CBCT planes (dorsal, s...
Maleas G, Hargitaiova K.To macroscopically characterize and compare the open Metzenbaum (FOM) and ultrasound-guided (FUG) plantar fasciotomy techniques for decompression of the hindlimb proximal suspensory ligament (PSL), and to determine whether either approach induces intraligamentous splitting (ILS). Methods: Cadaveric experimental study. Methods: Paired hindlimbs from 10 adult horses with no history of hindlimb lameness. Methods: Each horse contributed one limb to FOM and the contralateral to FUG. All procedures were performed by a single surgeon, and incision measurements were obtained by a blinded examiner. Ski...
Jasiński T, Borowska M, Juszczuk-Kubiak E, Turek B, Kaczorowski M, Bąk M, Żuk J, Domino M.Horses presenting with temporomandibular joint (TMJ) dysfunctions are often clinically evaluated for TMJ osteoarthritis (OA). Due to the unique characteristic of TMJ-related pain, the clinical diagnosis of equine TMJ OA is challenging; however, it may be supported by computer-aided tools incorporating biomarker data. This study aims to evaluate a machine learning-based approach to address a binary classification distinguishing healthy TMJs from TMJ OA. Among 50 equine cadaver heads, 82 TMJs were included and annotated as healthy or OA based on histological and computed tomography (CT) findings...
Pye E, Marcilla MG, Duncan JC.Regional anaesthesia of the equine anogenital tract is limited to local infiltration, extradural, blind palpation and nerve stimulator-guided techniques which risk iatrogenic damage, recumbency and ataxia. This study aimed to describe and assess the feasibility of transcutaneous ultrasound-guided (USG) pudendal nerve staining in equine cadavers. An initial pilot phase used two fresh equine cadavers and one standing unsedated horse to image the intrapelvic anatomy using ultrasound. One fixed equine cadaver specimen was also dissected to identify the pudendal nerve and refine the dissection appr...
Smith MA, Ripley N, Gravatte H, Nielsen MK.With rising anthelmintic resistance in adult cyathostomins, the most pervasive equine parasites, the need to assess larvicidal efficacy has increased, yet available methods remain limited. Encysted larvae are quantified using mucosal digestion, wherein a 5% subsample of intestinal mucosa is processed, and a 2% aliquot is counted for early third stage (EL3) and late third stage/mucosal fourth stage (LL3/L4) larvae. This method is imprecise and post-treatment larval differences are often not observed. The following study aimed to assess standard and modified protocol precision and sensitivity. I...
Belova N, Malle A, Schieder K, Licka TF.For centesis of the equine navicular bursa radiographs confirming needle placement are recommended, this can be a logistical challenge. Therefore, we aimed to identify the usefulness of radiographic measurements for centesis of the navicular bursa. On lateromedial radiographs localization of the centre of the flexor surface of the navicular bone was determined in 26 isolated limbs. Based on these measurements, 21 novice veterinary students performed 130 needle placements using the axial distal palmar technique injecting one of five dyes per cadaver limb. Success was identified on dissection as...
