Gross and ultrasonographic anatomy of the carpal flexor tendon sheath in horses. This study was undertaken to establish the gross anatomy and the ultrasonographic appearance of the carpal digital flexor tendon sheath (carpal sheath) and the palmar carpal region in normal horses. The isolated forelimbs from 15 horses were used to study the morphology of the sheath and associated structures, including a detailed study of the location of the main blood vessels and nerves in that region. These limbs and the forelimbs of five live, sound horses were also examined ultrasonographically. The examination yielded good soft tissue detail of the tendons and ligaments, synovial and per...
Influence of the force applied and its period of application on the outcome of the flexion test of the distal forelimb of the horse. The influence of the force applied and its period of application on the outcome of the flexion test of the distal forelimb was investigated in a group of eight sound horses. The degree of lameness after the flexion test was scored by a standard clinical classification, and by measuring the angle of maximum fetlock extension by means of the infrared light-based MacReflex gait analysis system. There was a good correlation between the clinical score and this electronically recorded kinematic parameter (r = 0.96). Both the force applied and the period of application affected the outcome of the tes...
Variations in the force applied to flexion tests of the distal limb of horses. A pressure-sensitive device was developed to measure the force applied to flexion tests of the distal limb of horses. The mean force applied by a group of experienced clinicians was 150 N which results in a moment on the flexed fetlock joint of about 28.5 Nm. The coefficient of variation of the force applied by one experienced clinician was only about 12 per cent, but the coefficient of variation between clinicians was considerably higher (20 per cent), irrespective of whether the clinicians were considered to be experienced or not. The mean force applied by a group of women examiners (114 N) ...
Comparative studies of ivermectin and moxidectin in the control of naturally acquired cyathostome infections in horses. The control of naturally acquired cyathostome infections in horses by treatments with ivermectin and moxidectin was evaluated in three field studies. In a first study the efficacy of both drugs was assessed in a faecal egg count reduction test. Both ivermectin and moxidectin demonstrated efficacies greater than 99 per cent for up to 60 days after treatment. In a second study, the period required for strongyle eggs to reappear was estimated in horses treated either with ivermectin or moxidectin. For the horses treated with ivermectin the period varied between 10 and approximately 13 weeks, and ...
Management of headshaking in three horses by treatment for protozoal myeloencephalitis. Unlike the incidence of equine protozoal myeloencephalitis (EPM), which appears to be increasing, headshaking is an uncommon problem for horses in Missouri and the adjacent states. Equine protozoal myeloencephalitis was incriminated in three horses examined for the treatment of headshaking on the basis of a neurological examination, an analysis of cerebrospinal fluid and their response to treatment. The headshaking and stereotypical behaviour associated with EPM was successfully treated with potentiated sulphonamides and pyrimethamine.
Infectious temporomandibular joint disease in the horse: computed tomographic diagnosis and treatment of two cases. Diagnostic imaging and treatment of unilateral destructive temporomandibular joint disease in two horses is described and discussed. Computed tomography appeared to be the best imaging technique for these lesions. The disease can be followed by functional recovery after the infection has resolved.
Septic tenosynovitis and focal osteomyelitis of the lateral proximal sesamoid bone in a thoroughbred gelding. Chronic septic tenosynovitis with concurrent, associated focal osteomyelitis of the lateral proximal sesamoid bone was diagnosed in a seven-year-old thoroughbred gelding. Surgical management of this case consisted of open annular ligament desmotomy and curettage of the affected sesamoid. Following lavage of the digital sheath the incisional wound was closed but a 2 cm gap was left distally to allow for postoperative open drainage. The distal limb was bandaged and the horse treated with antibiotics and non-steroidal anti-inflammatories. Sepsis resolved and the horse made a gradual return to ful...
Surgical treatment of a comminuted articular fracture of the accessory carpal bone in a thoroughbred horse. The clinical, radiographic and ultrasonographic findings in a case of a comminuted articular fracture of the accessory carpal bone of a thoroughbred chaser are described, and its surgical treatment and aftercare are detailed. The horse made an uneventful recovery and successfully returned to racing.
Ageing draft and trotter horses by their dentition. The accuracy of ageing horses by their dentition was assessed by comparing the dental features with the known dates of birth of 212 trotter horses and 189 Belgian draft horses. The horses ranged in age from two to 25 years. In both breeds it was observed that the shedding of the incisors and the appearance of the dental stars were the most reliable features for age determination. In young animals, the dental configuration was similar in both breeds. With increasing age the incisor teeth of draft horses were more liable to abrasion than those of trotter horses. The sequential changes in appeara...
Comparison of standardbred trotters exercising on a treadmill and a race track with identical draught resistances. The responses in heart rate, plasma lactate and rectal temperature of standardbred trotters to draught loaded interval exercise on a treadmill and a race track were studied. The horses were exercised with incrementally increasing trotting speeds for two-minute intervals with draught loads of 10, 20 and 30 kilopond (kp) in three different tests. Each trotting interval was followed by two-minute periods at a walk without a draught load. Measurements of heart rate and plasma lactate were made at the end of each interval and the rectal temperature was taken at the end of the exercise. The heart ra...
Treatment of a keratoma in a Clydesdale horse. A keratoma was diagnosed in a six-year-old Clydesdale gelding with recurrent 'pus in the foot'. The keratoma was excised through an inverted 'V' dorsal wall hoof resection up to 2 cm distal to the coronary band, the foot was bandaged and shod, and the horse treated with antibiotics and phenylbutazone. The dorsal hoof wall regrew completely and the horse gradually returned to full work.
An outbreak of respiratory disease in horses associated with Mycoplasma felis infection. Lower respiratory tract disease developed in a group of racehorses in training between two and six years of age. Disease was observed in 22 of 25 horses for which full records were available. Seroconversion to Mycoplasma felis was demonstrated by indirect haemagglutination assay in 19 of 22 paired sera and high titres (> or = 64) were found in convalescent sera from the three remaining horses. Evidence of respiratory viral infection was confined to seroconversions to equine herpesvirus-4 in two of the horses. Tracheal wash samples, taken from four horses with visibly increased tracheal muco...
Swabbing protocols in screening for contagious equine metritis. Outbreaks of contagious equine metritis in Britain during 1996 emphasised the importance of preventing the disease through full and widespread implementation of the Horserace Betting Levy Board's code of practice. The provision of satisfactory samples for testing represents an integral part of applying the code. Here, in an article commissioned by the British Equine Veterinary Association, Dr Elaine Watson describes the techniques involved.
Surgical repair of the parotid gland in a gelding. The surgical repair of a traumatic injury to the parotid (Stenson's) duct of an adult horse is described and compared with previous reports. The diagnosis was confirmed by the analysis of a flow of saliva-like fluid observed while the horse was eating. The repair was attempted under general anaesthesia three days after the injury. Surgical anastomosis was considered to have improved the rate of healing. However, there was some evidence of leakage of saliva from the site for three days after the removal of the in-dwelling catheter, seven days postoperatively. A full recovery followed.
Use of the GnRH analogue, deslorelin acetate, in a slow-release implant to accelerate ovulation in oestrous mares. In two separate controlled clinical trials, the efficacy and safety of 2.2 mg of the GnRH analogue deslorelin, administered subcutaneously as a short-term implant to normally cycling mares in oestrus with a dominant ovarian follicle more than 30 mm in diameter, were evaluated, using a placebo as a negative control. The oestrous cycle of each mare was followed by teasing, palpation per rectum and transrectal ultrasonography. Follicles were monitored every 24 hours by ultrasonography until ovulation occurred. The mares were either mated naturally or inseminated artificially. In trial 1, 174 mare...
