Information for all cattle with a diagnosis of tendon injury entered into the Veterinary Medical Data Base (VMDB) was retrieved and selected medical records reviewed. The proportional morbidity rate for tendon disruption was 0.89 cattle/1,000 cattle admissions and 95 of 99 cattle survived. Female and dairy cattle had a greater risk of tendon disruption than male or beef cattle, respectively. Also, cattle 6 months to 7 years old had a greater risk than cattle younger than 6 months old. Complete medical records were examined for 27 cattle. Affected cattle were 2.5 ± 1.8 years old and weighed 593.6 ± 315.6 kg. Injuries were most commonly caused by accidents involving farm machinery (72%). Unilateral superficial digital flexor tendon injury occurred in 8 cattle (30%); multiple tendon injury occurred in the other 19 cattle (70%). A single limb was involved in 25 cattle, a rear limb was involved in 24 cattle, and an open wound was associated with the injury in 26 cattle. Wounds were identified most commonly at the mid (13 cattle) and proximal metatarsus (4 cattle). Treatment of tendon disruption included tenorrhaphy and casting (9 cattle), external coaptation, alone, (14 cattle), stall confinement, alone, (1 cow), and euthanasia or salvage (3 cattle). External coaptation was maintained for 74.4 ± 34.3 days, and total confinement period was 88.3 ± 59.5 days. Short-term complications included severe tendon laxity (one cow) and fatal septic peritonitis (one bull). Twenty-two of 24 cattle treated for tendon disruption survived. Follow-up information was available for 16 cattle; 14 cattle (87%) returned to productivity and 11 of 15 cattle with long-term follow-up (73%) were considered productive. Long-term complications included persistent lameness (56%) and persistent hyperextension of the digits (19%). 相似文献

Superficial digital flexor luxation has been described in dogs, horses, and cattle. To the authors' knowledge, it has not been reported in cats. In the case of this report, monofilament nonabsorbable suture material was used to repair a laterally luxating superficial digital flexor tendon in a cat. The repair was similar to that which has been described in dogs. Whereas many etiologies of superficial tendon luxation have been proposed in dogs, trauma was believed to have contributed to the tendon luxation in this cat. 相似文献

Ultrasound machines with 7.5 to 5.0MHz linear transducers are well suited for rapid and straightforward differentiation of soft tissue swelling in the musculoskeletal system of cattle; in proximal limb regions 3.5MHz convex scanners allow better imaging. The main indications for ultrasonography of the musculoskeletal system in cattle are suspected arthritis, tenosynovitis, bursitis, abscesses, haematomas, diagnosis of muscle and tendon lesions, and generally the evaluation of soft tissue swellings everywhere that cannot be diagnosed based on clinical examination. The examiner starts by obtaining a general overview of the affected region for orientation purposes. This is achieved by locating and identifying anatomical landmarks, thereafter one can search for pathological changes by examination of the region of interest in longitudinal and transverse planes from all sides. The ultrasonographic investigation should follow a standardised systematic protocol. Normal synovial cavities in cattle are difficult or impossible to visualize via ultrasonography because of the very small physiological amount of synovial fluid. Thus, effusion that is easily visualized usually indicates a pathological process like arthritis, tenosynovitis or bursitis. Ultrasonography provides accurate information about the location and size of lesions or fluid-filled cavities, the nature of the content and an exact measurement of the distance from pathologically altered structures to the skin surface. Targeted centesis of synovial or other cavities can be carried out after a preliminary ultrasonographic inspection. Characterization of the lesions and a thorough preoperative inspection of affected regions are of enormous benefit for planning surgery and treatment. 相似文献

Endoscopy of the Digital Flexor Tendon Sheath in Horses 总被引：1，自引：0，他引：1
An arthroscopic procedure for examination of the digital flexor tendons and tendon sheath was developed in 16 equine limbs and 12 horses. Distension of the tendon sheath and insertion of the arthroscope was accomplished through a cul-de-sac on the palmar or plantar surface of the tendon sheath 1 to 2 cm palmar or plantar to the digital neurovascular structures and between the annular ligament and proximal digital annular ligament. A single arthroscope entry point allowed examination of all regions of the tendon sheath cavity and most surfaces of the digital flexor tendons within the sheath. Distal to the fetlock, surgical procedures could be performed through additional entry portals on the lateral, medial, or palmar surfaces of the tendon sheath. The palmar digital vessels and nerves were avoided by palmar placement of the instrument incisions and insertion of a needle before incising the skin. The fetlock canal and proximal regions of the tendon sheath were examined by redirecting the arthroscope. Flexion of the fetlock aided passage of the arthroscope into the proximal tendon sheath regions. Evaluation of the palmar surface of the superficial digital flexor tendon was limited by the midline attachment of the tendon sheath, otherwise the surfaces of the tendons and tendon sheath could be examined with 25 degrees and 70 degrees arthroscopes. The tendon sheath was more tightly invested to the tendons in the proximal regions, limiting the arthroscope movements and second instrument access. 相似文献

A heel extension shoe was used as an adjunct to primary tendon repair in a dairy cow. A shoe was placed on the foot for 6 weeks after the foot had been immobilized for 6 weeks in a cast. The shoe was continuous across the toes to provide even support for both claws and was nailed and clinched in the same way a shoe is applied to a horse's hoof. Special adaptations included drilling nail holes closer to the rim of the shoe to accommodate the narrower bovine hoof wall. The cow was permitted controlled exercise for gradual remodeling and strengthening of the tendon repair. When the shoe was removed 12 weeks after surgery, the metatarsophalangeal and distal interphalangeal joints were in normal posture. We consider application of a therapeutic shoe to be an important adjunct to surgical repair of major tendon injuries in adult cattle. 相似文献

A new surgical approach to the infected fetlock joint is described in two cattle suffering from septic tenosynovitis of the lateral digital flexor tendon sheaths of the right lateral hind-digits with concurrent septic serofibrinous arthritis of the adjoining fetlock joints, caused by penetrating wounds. In both patients, the infected sheaths were opened and the superficial and deep digital flexor tendons were removed. Intraoperatively, a small entry through the fetlock joint capsule was detected, directly distal to the lateral proximal sesamoid bone. The tract was surgically enlarged and a second approach into the plantar fetlock joint pouch was created proximally by making a 3 cm long and 0.5 cm wide incision between the two lateral suspensory ligament branches. This allowed easy access to the plantar joint pouch, removal of fibrin clots and an effective joint lavage using 5L of sterile saline solution. The incisions of the fetlock joint capsules remained unsutured and were drained using soft polyurethane foam to preclude premature closure. The tendon sheath wounds remained unsutured. In both patients, the digital flexor tendon sheath and the fetlock joint were lavaged daily for the following three days. The infection was eliminated in both cattle and both fully recovered without residual lameness. 相似文献

Nine foals, aged 4–7 months, suffering from contracted deep digital flexor tendon were radiographed for changes in the distal phalanx. Varying degrees of osteolysis in the distal part of the distal phalanx were observed. The foals with the most pronounced clinical signs also displayed the most prominent radiologic changes. Tenotomy of the check ligament of the deep digital flexor tendon was performed. In severely affected foals, a shoe with a long toepart was used after surgery. Programmed exercise on hard ground was started 1 week after surgery. Control radiography was performed on three of the foals 1–1½ years after treatment. At that time, the colts had normal distal phalanges and their function and mobility were normal. Of the remaining six animals, three had been sold as being healthy and were not available for examination. The remaining three had been examined for the first time within the last 3 months, and long-term evaluation was not possible. 相似文献

Lesions of the manica flexoria are a tenoscopic finding in horses with digital flexor tendon sheath tenosynovitis. This retrospective case series study describes the ultrasonographic findings in seven horses admitted for digital flexor tendon sheath swelling associated with lameness and tenoscopic confirmation of a manica flexoria tear. Six horses had a partial manica flexoria tear, one a complete rupture. The ultrasonographic examination included a static examination on the weight and non‐weight bearing limb and a dynamic limb assessment during flexion and extension. The main ultrasonographic finding at the static weight bearing examination in horses with a partial tear was an asymmetrical appearance of the manica flexoria at the level of the junction with the lateral border of the superficial digital flexor tendon, or an incomplete visualization of the manica flexoria in case of complete rupture. The split edges of the completed ruptured manica flexoria were seen floating in the synovial fluid at the examination in flexion. In six of seven cases, the superficial digital flexor tendon slid abnormally relative to the deep digital flexor tendon, during flexion/extension movements, with medial displacement of the superficial digital flexor tendon, appearance of an anechoic gap between the flexor tendons or reduced superficial digital flexor tendon sliding. Because ultrasonographic diagnosis of the manica flexoria tear is considered challenging, detection of these ultrasonographic features is helpful to increase the likelihood of identifying manica flexoria tears prior to tenoscopy. Authors recommend static ultrasonographic examination of the manica flexoria using a flexed limb position and dynamic ultrasonographic examination using flexion and extension positioning for horses with suspected digital sheath injury. 相似文献

The relation between the active form of tuberculosis in persons working in agriculture and incidence of tuberculosis in cattle was analyzed in 1974 to 1978, i.e. in the period after the elimination of bovine tuberculosis in Czechoslovakia (in 1968). M. tuberculosis was isolated in 15 cases and M. bovis in four cases of persons employed by the farms on which the Regional Hygienic Station, Brno, was responsible for the microbiological diagnostics of tuberculosis. Direct contact with animals was demonstrated in eight patients; M. tuberculosis was isolated from seven of these patients and M. bovis from one. Seven cattle herds were exposed to spontaneous infection by M. tuberculosis and in one of them tuberculosis was not demonstrated during complex examination. In three herds the examination revealed only a sensitivity of cattle to mammalian tuberculin. In other three herds tuberculosis was detected by allergic tests, patho-anatomic examination and bacteriological examination. M. tuberculosis in cattle was detected in two herds. The occurrence of bovine tuberculosis caused by a cattle tender with a positive finding of M. bovis in sputum was demonstrated in one herd. Virulence for the tested cattle was found in one strain (isolated from a mesenterial lymph node of cattle) of the four strains of M. tuberculosis used for the experimental infection of 17 animals. On the other hand, in three strains of M. tuberculosis, trials with experimental infection demonstrated only allergy to mammalian tuberculin and changes at the sites of subcutaneous inoculation of mycobacteria of regressive nature; these mostly disappeared within 90 days from infection. 相似文献

The objective of this report is to present the most important indications for the use of Ligasano-polyurethane-soft-foam dressing material in the treatment of infected wounds in cattle. For this study, 28 cattle were selected, which were treated at the clinic (2000-2003) for infected cut, puncture and laceration wounds on the limbs, purulent tarsal hygromas, large abscesses in the tarsal, crural and thigh regions, and purulent tenosynovitis of the digital flexor tendon sheath caused by penetrating puncture wounds. After routine wound cleansing, debridement or adequate surgery with wound lavage, Ligasano-polyurethane-soft-foam (Ligamed Medical Produkte, Cadolzburg-Wachendorf, Germany) was applied as a primary wound dressing instead of the conventional cotton gauze swabs or as drainage material in all these wounds. The porous surface structure of this material caused subtle wound debridement and mechanical stimulation of the wound surface increasing exudation and decreasing fibrinous adhesions. The pores ensured good drainage, reduced infection, avoided the accumulation of exudate and the following destruction of the wound surface. In all these indications, except abscesses and purulent hygromas, no or only slight purulent exudation of the treated wounds was observed. Especially in the treatment of purulent tenosynovitis of the digital flexor tendon sheath with tendon resection a rapid healing of these large surgical wounds--often within 2 weeks--was found. The therapeutic effect of Ligasano-polyurethane-soft-foam as a primary wound dressing was so convincing in these bovine patients, that it is now used exclusively as primary wound dressing material for treatment of infected wounds. 相似文献

OBJECTIVE: To describe the ultrasonographic appearance of the normal and diseased biceps brachii tendon and its tendon sheath in dogs. STUDY DESIGN: A prospective clinical study. ANIMALS: One hundred twenty client-owned dogs. METHODS: In the first part of the study, the ultrasonographic appearance of the normal biceps brachii muscle and the surrounding soft tissue was determined in 27 healthy dogs. Standard views were described and established. In the second part, 120 dogs with suspected pathology of the biceps brachii muscle were examined ultrasonographically. Fifty-five of these dogs had no sonographic changes, and 65 dogs had sonographically detectable pathologic changes of the tendon or the tendon sheath or both. The mean age of the affected dogs was 3.7 years. The ratio of males to females was 1.95:1. Sedation or anesthesia of the dogs was required because of the extreme movements of the leg necessary for the examination. To achieve a perpendicular view of the tendon and the tendon sheath, the area of the shoulder joint was rotated outward and abducted as far as possible. Examination of the muscle-tendon apparatus of the biceps brachii muscle was divided into 4 main sections. RESULTS: Linear transducers (7.5-10 MHz) allowed the soft tissue structures to be easily visualized with ultrasonography. Pathologic changes of the tendon and tendon sheath were visualized sonographically by using high-frequency linear probes. Partial or complete tendon rupture, medial luxation of the tendon, corpora libera in the tendon sheath, and tenosynovitis were clearly shown. CONCLUSIONS: High-frequency ultrasonography using linear transducers allows the examiner to accurately define the pathologic changes in the region of the biceps brachii tendon in dogs. CLINICAL RELEVANCE: The use of sonography for diagnosis of disease processes of the tendon and tendon sheath of the biceps brachii muscle complements clinical and radiographic examination findings. 相似文献

The value of ultrasonography in the diagnosis of lesions of the Achilles tendon was Investigated in 42 dogs and seven cats. A standardised four-part ultrasonographic examination was established. Linear transducers with a frequency of more than 7.5 MHz were used. Ultrasonography allowed identification and differentiation of total ruptures and the differentiation of partial ruptures into deep or superficial ruptures, or those comprising muscular tears. The healing process could be monitored and imaged using this technique. Suture material was readily visible in surgically treated cases. Displacement of the superficial digital flexor tendon could be identified. In such cases, the tendon tissue was seen either medially or laterally to the calcaneus. The healing process of the Achilles tendon could also be documented using ultrasonography. However, it was not possible to determine the age of the injury and the exact end of the healing process. Ultrasonography therefore proved to be an excellent diagnostic method for imaging lesions of the Achilles tendon and associated injuries in dogs and cats. After physical examination, the technique should be the next logical step in the evaluation of a suspected injury to the Achilles tendon. 相似文献

The stifle region of 18 healthy cattle (14 cows, four bull calves) and the stifles of five bovine cadavers were examined using 7.5 MHz linear or convex and 5 MHz sector transducers. The normal ultrasonographic appearance of soft tissues and bony structures was studied.The homogeneously echogenic patellar and collateral ligaments, the combined tendon of the long digital extensor and peroneus tertius muscles, the popliteus tendon, the anechoic articular cartilage of the femoral trochlea, the echogenic menisci and the hyperechoic bone surfaces were imaged successfully in all cattle and cadavers. The boundaries of the joint pouches only became partially identifiable, when small amounts of anechoic fluid were present in the medial and lateral femorotibial joint pouches. After experimental filling in cadavers, the distended synovial cavities were imaged as clearly demarcated, anechoic areas. Measurement values of cross-sectional diameters of the ligaments, tendons and the popliteal lymph node, the width of normal joint pouches, where visible, and articular cartilage thickness are presented. The established results should serve as reference data for ultrasonography of bovine stifle disorders. 相似文献

Avulsion of the insertion of the triceps tendon, which had a pre-existing tendinopathy, is described in a cat. The tendon was re-attached to the olecranon and the repair was immobilised using a type la trans-articular external skeletal fixator. The treatment was successful, however, mild and intermittent lameness persisted. Although it is an uncommon condition in small animals, the diagnosis should be based on careful clinical and radiographic examination. 相似文献

A herd of cattle was accidentally exposed to monomeric acrylamide and N-methylolacrylamide. Seven cattle underwent repeated examinations during 6–8 months after exposure. Abnormal pupillary light reflexes (PLR) were observed in one cow. Ophthalmoscopic examination showed progressive retinal degeneration and degenerative changes in the optic nerve heads in this cow. Light and electron microscopic examination revealed pathological changes in the retinae and optic nerves consistent with chronic stages of acrylamide toxicity. Ophthalmic examination and light microscopy did not reveal abnormalities in the retinae or optic nerves in either the rest of the cattle from the herd or in offspring of exposed cattle. 相似文献

We compared contrast-enhanced computed tomography (CT) and high field magnetic resonance (MR) imaging in a horse with deep digital flexor tendonopathy. Lesions in the distal extremity were documented grossly and histopathologically. In contrast-enhanced CT, the deep digital flexor tendon lesions were markedly contrast enhancing with evidence of angiogenesis in the core and dorsal border lesions. The lesion morphology was clearly delineated on MR imaging, but without contrast media angiogenesis cannot be identified. Gross examination, histopathologic examination, and CD31 immunohistochemistry confirmed the tendonopathy and an increased presence of small blood vessels. In this horse, deep digital flexor tendon lesions appeared similarly on contrast-enhanced CT and MR imaging. Contrast-enhanced CT may be an alternative to MR imaging for assessing tendon and ligament injury in the digit of the horse. 相似文献

An indirect immunofluorescent antibody test (IFAT) and an enzyme-linked immunosorbent assay (ELISA) for specific anti-Neospora antibodies in bovine sera and foetal fluids were compared with histological examination results on aborted foetal material. The agreement between serological and histological examination results was poor, while the two serological tests showed a high degree of agreement. Serological testing of diagnostic serum samples and foetal fluids suggests that the prevalence of anti-Neospora antibodies in cattle which recently aborted is around 40%, in line with previous estimates of the number of abortions in dairy cattle caused by Neospora sp. A sero-epidemiological approach to the diagnosis of Neospora abortions in cattle may be suggested from these data. 相似文献
