Resumo
The clinical manifestations of diseases of the locomotor system generates discomfort and pain, which can trigger lesions, the severity of which provides an abnormal distribution of weight, resulting in overloading joints, tendon and ligaments. Imaging studies are presented as a valuable tool to evaluate the degree of impairment of digital anatomical structures. The objectives of this study were carrying out a literature review on the applications of ultrasound in the distal ends of the locomotor limbs cattle and describe the sonographic anatomy of the structures that make up the metacarpo/ metarsophalangeal and interphalangeal joints, measuring the superficial digital flexor tendon (SDFT) and deep (DDFT) of young cattle during three stages of growth. Were employed nine Nelore calves and seven Girolando. During 120 days, the animals were managed intensively, they were weighed and subjected to clinical, radiographic and ultrasound with eight, ten and twelve months. In the clinical evaluation of the 64 distal ends, it was found that 37 (57%) showed horizontal lines of stress. Radiography of the three moments revealed no bone lesions. The measures taken by ultrasonography cross-sectional thickness of the SDFT and thickness and width of DDFT were similar (p ≥ 0.05) between the breeds, and SDFT for the minimum and maximum values observed for Nelore (lateral: M0 = 1.98 ± 0.24 mm, M2 = 2.83 ± 0.27 mm and medial M0 = 1.98 ± 0.20 mm, M2 = 2.66 ± 0.13 mm) and for Girolando (lateral: M0 = 1 , 97 ± 0.20 mm, M2 = 2.54 ± 0.14 mm and medial M0 = 1.90 ± 0.13 mm, M2 = 2.57 ± 0.12 mm). For DDFT the following minimum and maximum values observed for Nelore (lateral thickness: M0 = 5.53 ± 0.76 mm, M2 = 7.07 ± 0.36 mm/lateral width: M0 = 12.98 ± 1.18 mm; M2 = 15.33 ± 0.40 mm/medial thickness: M0 = 5.38 ± 0.68 mm, M2 = 7.21 ± 0.31 mm medial/width: M0 = 13.49 ± 1.10 mm, M2 = 15, 52 ± 0.50) and for Girolando (lateral thickness: M0 = 5.23 ± 0.78 mm, M2 = 6.93 ± 0.18 mm/lateral width: M0 = 12.57 ± 0.93 mm, M2 = 15 , 46 ± 0.46 mm/medial thickness: M0 = 4.70 ± 0.43 mm, M2 = 7.00 ± 0.37 mm medial/ width: M0 = 12.84 ± 0.98 mm, M2 = 15.28 ± 0 56). The structures visualized by ultrasound examination of the dorsum of the distal epiphysis of the metacarpus/ tarsus, were longitudinal growth plate, the condyles of the metacarpal/tarsal bones, joint capsule, common extensor tendon of the third finger and the joint space. In the interphalangeal region was observed the extensor tendon of the third finger and medial extensor, proximal, middle and distal phalanges and the joint space. In the palmar/plantar portion of metacarpal/ tarsophalangeana joint were observed the median and metatarsal plantar arteries, SDFT, DDFT, digital tendon sheaths, joint recesses and interosseous muscle. Distal to the dorsal region of dew claw was observed the annular digital distal ligament and in reversal of the positioning between the SDFT and DDFT. The sonographic characteristics observed on examination of the distal end of bovine Nelores and Girolandos aged between eight months and one year are indicated for satisfactory identification of these structures for cattle with similar characteristics, as well as measurements of thickness and width of the SDFT and DDFT values are reference to cattle of these ages.
