Veterinary procedures in horses encompass a range of medical and surgical interventions performed to diagnose, treat, and manage equine health conditions. These procedures are designed to address various health issues, from routine care to emergency interventions. Common veterinary procedures include vaccinations, dental care, lameness evaluations, reproductive services, and surgical interventions such as colic surgery or fracture repair. This page compiles peer-reviewed research studies and scholarly articles that explore the methodologies, outcomes, and advancements in veterinary procedures for horses, providing insights into their application and efficacy in equine medicine.
Robinson EP, Natalini CC.Intercoccygeal, or caudal, epidural injection of local anesthetics is a convenient method of producing analgesia and local anesthesia of the tail and perineal structures in conscious standing horses. This technique has been further developed to provide long duration analgesia and anesthesia by placement of catheters into the epidural space of horses. More recently, opioid, alpha-2 adrenergic agonists, ketamine and other analgesic agents have been administered by caudal epidural injection, providing pain relief in both conscious, standing and anesthetized, recumbent horses. This chapter describ...
Mama KR.Many new or modified injectable anesthetic techniques are available for use in horses. This increased availability allows the clinician to select the technique most appropriate for the patient and clinical circumstance. The use of sedative and anesthetic drugs in managing a variety of anesthesia-related and unrelated aspects of patient care is also increasing. As we begin to use these techniques in the clinical management of our patients, it is important to remember that, while there are more options, no single anesthetic agent or combination of agents is devoid of undesirable effects. Knowled...
Martinez EA.In summary, with proper vigilance, neuromuscular blocking agents can be used safely in anesthetized equine patients to optimize conditions for certain surgical procedures. By appropriate use of neuromuscular monitoring techniques and reversal agents, residual blockade and muscle weakness should be avoided, allowing the horse to recover to standing without difficulty. Research is ongoing to develop the ideal muscle relaxant, one that has a rapid onset, predictable duration and recovery times, and negligible hemodynamic effects. As newer agents become available, they should be evaluated for thei...
Taylor PM, Pascoe PJ, Mama KR.This chapter begins by providing an overview of current philosophies relevant to equine pain management. Objective and subjective techniques for assessing pain and the limitations of these are then described in depth. The conclusion emphasizes the need for an evidence based approach to managing pain in the horse and sets the stage for subsequent chapters in this edition.
Daunt DA, Steffey EP.Administration of alpha-2 agonists to horses produces a variety of behavioral effects (sedation, somnolence, analgesia), and physiological effects. One of the most significant beneficial effects of administering alpha-2 agonists is the degree of analgesia they provide. Alpha-2 agonists have been the mainstay of analgesia for colic pain in horses since their introduction to clinical veterinary medicine. The increased potency of the more recently introduced alpha-2 agonists allows the provision of analgesia for conditions not previously relieved by other drugs. Unfortunately, there are significa...
Baller LS, Hendrickson DA.Pain management is an extremely vital part of equine orthopedic surgery. Providing optimum analgesia for the patient will decrease recovery time, decrease physiologic stress on the animal, and provide maximum comfort during the post-operative period. The major analgesic drug categories and routes covered are nonsteroidal anti-inflammatory drugs, local anesthetics, intra-articular drugs, and epidurals.
Steffey EP.Both desflurane and sevoflurane offer theoretical and practical advantages over other inhalation anesthetics for horses. The lower solubility of both agents provides improved control of delivery and helps to counteract the confounding influence of the voluminous patient breathing circuit commonly used for anesthetizing horses. The lower solubility should account for faster rates of recovery compared with the older agents; whether or not the quality of recovery differs remains to be objectively evaluated in a broad range of circumstances. The pharmacodynamic effects are, in large part, similar ...
Mader Ch, Geisel O, Gerhards H, Hermanns W.In the present work transponders of 2 identification systems have been implanted on an exactly defined site at the bottom of the ear on 28 horses. The Backhome system is easier to handle and less complicated than the trovan system since it is smaller and handier. The hemorrhages that had occurred after the injection were mild at 17 animals and moderate at 4 animals. Inflame changes at the injection site post application were limited to minor swellings (n = 3) and minor pain (n = 6). The interrogator's scope of the two transponder systems is different. The interrogator's scope of the trovan tra...
Davidson HJ, Pinard CL, Keil SM, Brightman AH, Sargeant JM.The ocular effects of latanoprost ophthalmic solution were evaluated in two studies, with eight horses in each study. One eye of each horse was treated with latanoprost ophthalmic solution once daily for 5 days, and the opposite eye received a control solution of sterile eyewash. Intraocular pressure and pupillary diameter were measured daily for 5 days after treatment. Latanoprost had no significant effect on intraocular pressure or pupillary diameter in normal horse eyes compared with control eyes in these studies. Placement of an eyelid nerve block resulted in significantly lower intraocula...
Clark P, Mogg TD, Tvedten HW, Korcal D.Delayed analysis of blood samples may be caused by restricted access to laboratories. Artifactual changes may occur in the measured analytes as a consequence of delayed analysis and may complicate interpretation of the data. Objective: The purpose of this study was to characterize artifactual changes in equine blood, due to storage, using the Advia 120 hematology analyzer. Methods: Samples of blood from 5 horses were analyzed using the Advia 120 soon after collection and again after 24 and 48 hours of storage at either 4 degrees C or ambient laboratory temperature ( approximately 24 degrees C)...
George JW, O'Neill SL.Most hand-held medical refractometers have internal scales that limit protein measurement to results >/=2.5 g/dL. Tables for conversion of refraction (r) to protein concentration for values as low as 0.1 g/dL were published in the 1960s, but their accuracy for use on body fluids has not been established. The purpose of this study was to assess the reliability of body cavity fluid protein determination by refractometry. We compared the protein concentration of 25 body cavity fluids as determined by 2 Goldberg type hand-held refractometers with results obtained by the biuret method. Published...
Matthews S, Dart AJ, Reid SW, Dowling BA, Hodgson DR.To determine the predictive values, sensitivity and specificity of abdominal fluid variables associated with the need for surgery in horses with an acute abdominal crisis. Methods: Retrospective study. Methods: Two-hundred and thirty-six horses examined for signs of abdominal pain between January 1993 and June 1999. Methods: Breed, age and gender of the horse and colour, total protein concentration and total nucleated cell count of an abdominal fluid sample were recorded. Colour of the abdominal fluid was classified as normal if it was yellow and transparent. Turbid fluid or fluid that was ser...
Alexander GR, Gibson KT.Two mares presented with life-threatening rectal tears were successfully treated with intensive medical management. Although surgery has been regarded as mandatory for grade 3 or 4 rectal tears in the past, recent reports have indicated the value of medical management alone. The case reports presented in this article detail the use of antibiotics, flunixin meglumine, laxative diets and faecal softeners in the medical management of two mares presented with grade 3 rectal tears.
Kirkham LE, Vasey JR.An Anglo-Arab foal with bilateral postprandial nasal discharge was diagnosed as having a full-length defect of the soft palate. Surgical repair was attempted using a combination of two surgical approaches. Initially a mandibular symphysiotomy approach was used. The posterior portion of the defect did not heal adequately, so a ventral laryngotomy, bisecting the body of the thyroid cartilage and extending to a pharyngotomy approach, was performed 5 months later. The foal has since matured fully despite a slight unilateral nasal discharge. This case report demonstrates that these two surgical app...
Van Hoogmoed LM, Agnew DW, Whitcomb M, Hyde DW, MacDonald MH, Snyder JR.To describe the ultrasonographic and quantitative histologic effect of injecting 2% iodine in almond oil (IAO) and ethanolamine oleate (EO) in the medial and middle patellar ligaments of horses and to determine whether a difference in response exists between IAO and EO treatment. Methods: 10 healthy horses. Methods: In 5 horses, the medial and middle patellar ligaments of 1 limb were injected with EO, whereas IAO was injected in the medial and middle patellar ligaments of another 5 horses. Ultrasonographic evaluation was performed on the experimental and control limb before injection of IAO an...
Kidd JA, Slone DE.The medical records of 80 horses treated for left laryngeal hemiplegia by prosthetic laryngoplasty, ventriculectomy and vocal cordectomy were examined, first to compare the subjective and objective success rates for groups of horses of different ages and used for different purposes, and secondly, to compare the efficacy of including vocal cordectomy in the surgical protocol with published success rates for laryngoplasty and ventriculectomy alone. Subjectively, 70 per cent of the horses were said to have had a successful surgical outcome. The success rate for thoroughbred racehorses (66 per cen...
Theoret CL, Barber SM, Moyana TN, Gordon JR.To determine whether transforming growth factor (TGF)-beta1 and -beta3 expression differs between equine limb wounds healing normally and those healing with experimentally induced exuberant granulation tissue (EGT). Methods: Six wounds were created on the lateral aspect of both metacarpi of each horse; one forelimb was untreated, and the other was bandaged to stimulate the development of EGT. Sequential wound biopsies allowed comparison of growth factor expression between the two types of wound. Methods: Four horses (2 to 4 years of age; 350 to 420 kg). Methods: Wounds were assessed grossly, h...
Galuppo LD, Stover SM, Aldridge A, Hewes C, Taylor KT.To compare monotonic mechanical properties of gap-ostectomized third metacarpal bones (MC3) stabilized with an MP35N interlocking nail system with contralateral intact bones. Methods: Twenty-four pairs of cadaveric equine MC3s.

Judy CE, Galuppo LD.To describe a technique for endoscope-assisted disruption and removal of urinary calculi using a holmium:YAG laser in sedated, standing horses. Methods: Retrospective study. Methods: Six horses with urinary calculi. Methods: A holmium:YAG laser was used to disrupt naturally occurring urinary calculi in horses (4 geldings, 1 stallion, 1 mare). Ischial urethrotomy was performed in male horses to provide a portal for the endoscope and laser fiber. Calculus fragments were removed by a combination of lavage, transendoscopic basket snare removal, forceps, and digital manipulation. Ischial urethrotom...
Andrea CR, Stover SM, Galuppo LD, Taylor KT, Rakestraw PC.To compare screw insertion characteristics and pullout mechanical properties between self-tapping (ST) and non-self-tapping (NST) AO 4.5-mm cortical bone screws in adult equine third metacarpal bone (MC3). Methods: In vitro biomechanical experiment. Methods: Seven pairs of adult equine MC3. Methods: Bicortical holes were drilled transversely in proximal metaphyseal, diaphyseal, and distal metaphyseal locations of paired MC3. NST screws were inserted in pre-tapped holes in 3 sites of one bone pair, and ST screws were inserted in non-tapped holes of contralateral MC3. Tapping and screw insertion...
McCauley CT, Hawkins JF, Adams SB, Fessler JF.To determine outcome of horses in which cutaneous masses were removed with a carbon dioxide laser. Methods: Retrospective study. Methods: 32 horses. Methods: Medical records of horses with 1 or more cutaneous masses treated with a carbon dioxide laser were examined. Follow-up information was obtained through telephone interviews with owners and referring veterinarians. Results: Cutaneous masses were classified as sarcoids (15 horses), neoplastic masses other than sarcoids (squamous cell carcinoma [91; fibroma [1]; and melanoma [1]), and nonneoplastic masses (6). Minimum follow-up time was 6 mo...
Traub-Dargatz JL, George JL, Dargatz DA, Morley PS, Southwood LL, Tillotson K.To determine current practices regarding use of antimicrobials in equine patients undergoing surgery because of colic at veterinary teaching hospitals. Methods: Survey. Methods: Diplomates of the American College of Veterinary Surgeons performing equine surgery at veterinary teaching hospitals in the United States. Methods: A Web-based questionnaire was developed, and 85 surgeons were asked to participate.

Smallwood JE, Wood BC, Taylor WE, Tate LP.The purpose of this study was to produce an anatomic reference for computed tomography (CT) of the head of the foal for use by radiologists, clinicians, and veterinary students. The head from each of 2 foals, euthanized for reasons unrelated to head pathology, was removed and prepared for CT scanning. Using a third-generation CT scanner, 5-mm contiguous transverse images were acquired. The heads were then frozen and sectioned using a band saw, with the cuts matched as closely as possible to the CT slices. The anatomic sections were photographed and radiographed. The radiographs and anatomic ph...
Weishaupt MA, Hogg HP, Wiestner T, Denoth J, Stüssi E, Auer JA.To develop and validate a novel instrumented treadmill capable of determining vertical ground reaction forces of all 4 limbs simultaneously in horses. Methods: Data obtained while a horse was walking and trotting on the treadmill. Methods: 18 piezo-electric force transducers were mounted between the treadmill frame and supporting steel platform to measure the actual forces at the corresponding bearing points. Each of the 18 sensor forces is equal to the sum of the unknown hoof forces weighted with the transfer coefficients of the corresponding force application points. The 4 force traces were ...
Harrison LJ, May SA, Edwards GB.Over a period of 16 years, 26 horses were treated for open fractures involving the splint bones. Treatment consisted of surgical excision of fracture fragments and sequestra, and curettage of infected and unhealthy tissues. The splint bone distal to the fracture was removed in nine horses in which the attachment of the splint bone to the cannon bone via the interosseous ligament did not provide adequate stability. In two horses it was considered necessary to stabilise the proximal fragment by internal fixation and infection developed in both of them; one of these horses was destroyed on humane...
Wong CH, Tang FP, Wan TS.The authors' laboratory at one time employed four liquid chromatography/mass spectrometric (LC/MS) methods for the detection of a large variety of drugs in equine urine. Drug classes covered by these methods included anti-diabetics, anti-ulcers, cyclooxygenase-2 (COX-2) inhibitors, sedatives, corticosteroids, anabolic steroids, sulfur diuretics, xanthines, etc. With the objective to reduce labour and instrumental workload, a new ultra performance liquid chromatography/tandem mass spectrometric (UPLC/MS/MS) method has been developed, which encompasses all target analytes detected by the origina...
Murray MD, Snowdon WA.The distributions of the following feral animals are given -- cattle, buffalo, pig, goat, deer, camel, horse, donkey, fox, dog and cat -- and the native dingo. The possible role these and the native rodents, marsupials and monotremes would play should an exotic disease of livestock enter Australia is discussed. It is considered that feral animals would be important in creating foci from which the disease would spread.
van Bergen T, Wiemer P, Martens A.Intestinal epiploic foramen entrapment (EFE) is an important differential diagnosis in horses with colic, but disappointing short- and long-term outcomes are reported in the scientific literature. Many horses are euthanased during surgery due to a predicted poor prognosis or due to uncontrollable intraoperative haemorrhage. The ileum is involved in the majority of cases. Several risk factors for the development of EFE are described; crib-biting/windsucking being the most important one. The recurrence rate of EFE is low despite the described risk factors, probably due to spontaneous closure of ...
Cowell RL, Tyler RD, Clinkenbeard KD, MacAllister CG.This article discusses collection, slide preparation, culture technique, fluid analysis and evaluation, and cytologic evaluation of peritoneal and pleural effusions. The morphologic characteristics of various effusions are described, and the physical characteristics (volume, color, turbidity) of effusions are discussed. An algorithm for classifying effusions as transudates, modified transudates, or exudates is included, and each category is discussed.
Specht TE, Poulos PW, Metcalf MR, Robertson ID.Vacuum phenomenon was induced inadvertently during radiographic examination of a metatarsophalangeal joint of a lame horse. The phenomenon was recreated in a sound horse when a metacarpophalangeal joint was radiographed in a stress-flexed position. Distraction of apposing articular surfaces may induce the vacuum phenomenon, which could result in misdiagnosis of an osteochondral defect or fracture.
Wolfers H, Böhm D.Etiology and therapy of equine esophageal obstipation are described in 79 cases seen at the Veterinary Surgery Clinic of the University of Munich.

Methods: Eleven horses (3-13 years) with periapical mandibular tooth infection. Methods: Hospital records (1992-2002) of horses that had periapical curettage for the treatment of mandibular cheek tooth root infection were retrieved. Clinical signs, radiographic, and surgical reports were reviewed. Outcome was obtained by telephone questionnaire for 7 horses and by physical examination in 2. Results: Eleven horses (14 infected mandibular molariform ...
Haven ML, Rottman JB, Bowman KF.A leiomyoma of the small colon was discovered incidentally in a 4-year-old Thoroughbred gelding during colic surgery to correct large colon displacement. The mass and 20 cm of small colon were resected, and an end-to-end anastomosis was performed. A postoperative fecal impaction proximal to the anastomosis responded after 5 days to administration of intravenous fluids, analgesics, and stool softeners.
Biedrzycki A, Markel MD, Brounts SH.To compare the in vitro biomechanical properties of a novel subcuticular stapling device to current methods of abdominal skin closure for equine abdominal surgery. Methods: In vitro randomized, matched design. Methods: Equine ventral median abdominal skin specimens (n = 24 horses). Methods: Subcuticular absorbable staples (SAS), metallic staples (MS), polyglyconate suture (PG), and nylon monofilament (NYL) were applied to longitudinally transected portions of equine ventral midline skin. Loads that resulted in an initial failure point and the ultimate failure load and mechanism were record...
Baxter C.This is a clinician's view of the current state of veterinary dentistry at the level of the general practitioner across the different species. An indication of the work done and the hazards commonly encountered are covered. Conclusions: To increase awareness within the dental profession of the current state of veterinary dentistry.
Lane JK, Cohen JM, Zedler ST, Hollis AR, Southwood LL.To describe a novel surgical technique for management of right dorsal colitis in the horse. Methods: Clinical report. Methods: 14-year-old Warmblood gelding. Methods: The horse was referred for treatment of a stromal abscess and signs of right dorsal colitis. Plasma chemistry revealed marked hypoproteinemia. Abdominal ultrasonographic examination showed a thickened right dorsal colon (RDC). Medical treatment was unsuccessful. With the horse in left lateral recumbency under general anesthesia, an approach to the right side of the abdomen through a 16th rib resection was made. The thoracic cavit...
Eggleston RB.Radiographic evaluation of a horse's foot gives tremendous insight into the relationship between the structures within the foot and between the foot and distal limb. The information gained from a radiographic study is highly dependent on the quality of the radiographs. A systematic approach should be taken when planning a radiographic study of the foot. Taking the time to examine the foot and prepare it properly will avoid the need, risk, and expense of repeating images and will improve the quality and therefore the interpretation of your radiographic images. When evaluating the foot for podia...
Trostle SS, Hendrickson DA.Suture sinuses formed in 3 horses following closure of ventral midline incisions with size-2 polypropylene. Suture sinuses healed after the suture material was removed. Suture sinus formation following closure with polypropylene may be related to the suture material's mechanical, rather than its chemical, properties. If polypropylene is used to close the linea alba in horses, the amount of tissue incorporated in the suture loops, suture tension, and knot volume should be minimized to decrease the risk of suture sinus formation.
Trump M, Kircher PR, Fürst A.Two fillies with hindlimb lameness and a tentative diagnosis of a pelvic fracture involving the acetabulum were examined using computed tomography (CT). The use of CT for these two cases revealed the exact course of the fractures and fissures, as well as the size and position of fragments, thus allowing for definitive diagnosis.
Zetterström SM, Johansson BC, Carmalt JL.OBJECTIVE To evaluate clinical and tenoscopic findings in a large group of horses undergoing surgery of the carpal flexor sheath (CFS) and determine whether any of the presurgical clinical signs were associated with tenoscopic findings. ANIMALS 242 horses that had undergone diagnostic and therapeutic tenoscopy of the CFS because of aseptic tenosynovitis. PROCEDURES Medical and tenoscopic video records (when available) of 242 horses undergoing tenoscopy of the CFS at a single equine clinic between January 2005 and June 2014 were reviewed. Tenoscopic findings were categorized as present or absen...
Smith WN.A system using a suitably sized flotation tank has been developed to reduce the weight that horses and cattle place upon their legs after undergoing surgery to their limbs. The system overcomes the need for the patient to lie down for long periods, thus preventing decubitus. The system is well tolerated with few side effects; after prolonged flotation alopecia may occur on those parts of the patient which remain continuously immersed in water. The method is now commonly referred to as the 'Queensland Sling'.
Smyth GB.A 4-year-old Quarter horse gelding presented with a swelling in the soft tissues over the junction of the body and ramus of the left mandible. Radiography showed a well circumscribed lytic area within the mandible surrounded by sclerosis unassociated with any tooth. Aspiration of the lesion yielded pus. The abscess cavity was opened, curetted and lavaged. A Penrose drain was placed in the abscess cavity for 10 days. Bacteriological culture of the exudate and soft tissues from the abscess produced a few colonies of Staphylococcus intermedius. Histopathology showed chronic pyogenic infection. Th...
Zamos DT, Parks AH.Medical records of 22 horses with humeral fractures were reviewed. The horses were from 2 to 144 months old (mean, 25.8 +/- 37.3 months). Ten horses were treated with stall confinement, 3 were treated surgically, and 9 were euthanatized at the time of diagnosis. Seven of 10 horses treated nonsurgically (stall confinement) were able to be ridden 5 to 12 months after the diagnosis was made (mean, 7.5 +/- 2.6 months). One horse treated nonsurgically was euthanatized 6 months after diagnosis because of laminitis in the contralateral limb. Two horses treated nonsurgically were lost to follow-up eva...
Gottschalk RD, van den Berg SS.Bilateral ovariectomy was performed in 11 mares and unilateral ovariectomy in 2 mares. The horses were standing and sedated for surgery. After appropriate preparation a laparoscope was inserted into the abdomen through the paralumbar fossa and the ovary was identified and anaesthetised with local anaesthetic via a custom-built needle. The ovary was then withdrawn from the abdomen through a separate flank incision and removed. The abdomen was not distended with gas before surgery. This method proved to be minimally invasive, rapid and effective.
Vera L, Decloedt A, Van Steenkiste G, De Clercq D, Govaere J, van Loon G.A 15-year-old Warmblood mare, at 8 months of gestation, was presented to the Ghent University Faculty of Veterinary Medicine for evaluation of suspected stage one labor. Transrectal ultrasonography revealed no clear signs of placentitis or stage one labor. The combined thickness of uterus and placenta was 11 mm and the cervix was closed. Twin pregnancy was suspected by transabdominal ultrasonography but could not be confirmed with certainty. An electrocardiogram (ECG) was recorded from the mare's abdominal wall to register a fetal ECG. To confirm twin pregnancy, registration of both fetal ECG...
Johnson KL, Hespel AM, Price JM, de Swarte M.Radiology can be a challenging subject for students and finding new techniques that help improve their understanding could have positive effects in their clinical practice. The purpose of this prospective experimental study was to implement the use of color-coded, three-dimensional-printed, handheld equine carpus models into a radiographic anatomy course and evaluate the impact objectively and subjectively using quizzes and student response surveys. A first-year veterinary class was randomly divided into two similarly sized groups (groups A and B) for an equine normal radiographic anatomy labo...
Vlaminck L, Cnudde V, Pieters K, Van Den Broeck W, Steenhaut M, Jacobs P, Gasthuys F.To evaluate the biological behavior of a nonresorbable bone substitute (NRBS) in the alveoli of ponies, compared with tissue quality in naturally healing alveoli, after cheek tooth extraction. Methods: 5 clinically normal ponies. Methods: In each pony, both maxillary fourth premolars (Triadan 108/208) were repulsed bilaterally during anesthesia. One randomly chosen alveolus was filled with NRBS and isolated from the oral cavity by use of dental impression material and a spring-wire retention device. The other alveolus was occluded in its occlusal third portion with dental impression material. ...
Dowling BA, Dart AJ, Trope G.Three horses with severely comminuted, open facial bone fractures and one horse with a comminuted, open orbital rim fracture were referred for treatment. Severe facial bone asymmetry and epistaxis were apparent in all cases and subcutaneous emphysema was present in two, however physical and neurological examinations were otherwise normal. Radiography and endoscopy were of some use in assessing the degree of damage, although the true extent of the damage was more apparent at surgery. Surgical reduction of the fractures was recommended to maximise cosmetic and functional outcome. After surgical ...
Sullins KE, McIlwraith CW.Transverse or oblique midshaft tibial osteotomies were created in 11 foals. The osteotomies were repaired during the same procedure using external skeletal fixation in either full splint or 3-dimensional (3-D) tent configurations. Four of the six foals receiving the full splint fixator recovered to full soundness; two were euthanized because of complications. The foals receiving the 3-D tent configuration would not bear weight on the limbs and consequently suffered significant secondary fracture disease. These foals were euthanized for humane reasons before the scheduled termination of the pro...
Reardon R, Bailey R, Walmsley J, Heller J, Lischer C.The mechanical properties of equine cervical vertebrae joined by implants have not yet been reported. Locking compression plates (LCP) may provide a useful alternative system to the commonly used stainless steel kerf-cut cylinders (KCC) currently used for fixation of cervical vertebrae in horses. Objective: The objectives of this study were to establish a method for biomechanical testing of equine C4-C5 articulations and to compare the biomechanical properties of cadaveric spines stabilised with KCC and LCP. Methods: Twenty-four equine cadaveric cervical spines were size measured from radiogra...
Maninchedda U, Nottrott K, Gangl M.This retrospective study on 37 horses was conducted to assess long-term complications, scarring, cosmetic appearance and owner satisfaction of horses that underwent transpalpebral enucleation with (n=26) or without (n=11) non-absorbable sutured meshwork prosthesis between 2006 and 2013. Postoperative complications related to the surgery were wound infection, discharge and dehiscence, and no significant difference between groups was found. In one horse, the meshwork had to be removed in order to treat a chronic fistula. Horses with infection or inflammation before surgery were more likely to en...
Park RD.A complete radiographic examination of the equine foot consists of properly exposed, processed, and positioned radiographs. For radiographic interpretation, in addition to knowing radiographic signs of disease, a knowledge of normal radiographic anatomy and possible insignificant anatomic variations is necessary.
Steinmetz A, Gittel C, Böttcher D, Lapko L, Offhaus J.A melanoma of the upper eyelid was resected in a gray warmblood gelding. A full functional eyelid could be obtained by completion a sliding skin graft with a free labial mucocutaneous graft transplantation to restore the mucocutaneous junction and to decrease the risk of postoperative trichiasis.
Lindsay WA, McMartin RB, McClure JR.Five cases of fracture of the third tarsal bone in racehorses are reported. A method of surgical correction employing a cortical bone screw is described in 2 cases. Healing of the fractures was followed radiographically. Surgical repair permitted both horses to return to competition. The 3 cases treated conservatively suffered a prolonged healing time and excessive new bone formation. They were unable to return to training due to persistent lameness.
