“…The distal level was located approximately 6 mm proximal to the apex of the distal phalanx [36]. Using the transverse view on the coronary band (Figure 3b) [9], the spatial relationship between it and the extensor process was established. Before being immersed for 24 h, each hoof was thoroughly cleaned and sanded.…”

“…Ultrasonography is a diagnostic technique widely used to evaluate structures associated with lameness in the distal part of the limbs of horses [ 1 ]. Several approaches to assessment of structures within the hoof have been described [ 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 ]. However, none fully evaluates the dermis, the epidermis, and the dermoepidermal junction (DEJ) of the digit.…”

Ultrasonography is commonly used to evaluate equine lameness-related structures, but traditional hoof approaches cannot adequately visualize internal structures such as the lamellar layer. To address this limitation, we used 62 healthy hooves without digital radiographic abnormalities, made up of thirty anatomical pieces (phase 1) and thirty-two hooves from living horses (phase 2). In both phases, half of the digits were submerged in water (group 1) and the other half in water and ice (group 2) for 24 h. Ultrasonographic views and temperature and humidity measurements were taken every two hours, and sagittal sections were obtained in phase 1. Good quality images were obtained in both phases. The transmural technique allowed the evaluation of several structures of the DEJ (tubular and lamellar strata of the hoof wall, sublamellar dermis, and solar and coronary papillae) and of the distal phalanx (extensor process, parietal surface, and apex). Our findings suggest that the transmural technique following hoof submersion can be useful for internal evaluation of hoof conditions, such as laminitis. However, further validation of the technique in natural or experimental cases is required.

“…The coronary band-extensor process (A), the distal phalanx apex-hoof wall (B), and the sole dermis (S) distances were also determined in a ultrasonographic sagittal view, with the exception of distance A, which was determined using the transverse view [1] at the level of the coronary band [29]. Distance A was determined by a diagonal line, and distances B and S were determinate by a perpendicular line to the parietal surface at the level of the apex of the distal phalanx.…”

“…Determining the anatomical relationship between the distal phalanx and the hoof capsule is diagnostically valuable, and radiographic evaluation is routinely used to estimate distances, angulations, and proportions to determine normality and deviations [11][12][13][14][15][16][17]. However, ultrasonography has not traditionally been considered a routine diagnostic aid for this purpose [21][22][23][24][25][26][27][28][29][30][31][32]. Previous studies using digital radiology and MRI have described the differences between the wall-soft tissues and the lamellar layer-sublamellar dermis, respectively [19].…”

The transmural ultrasound allows for the definition of the normal appearance of the hoof tissues and internal structures. Determining such measurements and proportions could contribute to evaluations of the normal spatial distal phalanx–hoof relationship. The objective was to describe the hoof’s dermis and epidermis measurements using the transmural technique, in comparison with DR and anatomical sections. Sixty-two healthy hooves without digital radiographic abnormalities, made up of 30 anatomical pieces (phase 1) and 32 alive horse hooves (phase 2), and 16 sagittal sections of the first ones were used. The proximal and distal planes were compared, defining the following measurements: coronary band-extensor process, distal phalanx apex–hoof wall, sole dermis, middle stratum, parietal dermis, lamellar layer, the sublamellar dermis, and ratios between them. Most of the measurements were consistent among methods. Some showed measurement differences and a minority was impossible to determine. The transmural technique allowed for the observation and replication of measurements of the hoof structures, described with other diagnostic aids. It also allowed for the implementation of new measurements that would help to determine the spatial location of the distal phalanx. Additionally, it contributes to the visualization of normal findings, which will be useful to compare variations in the different phases of laminitis.

“…Radiography is unreliable for detecting and grading DIP joint effusion. 15 The ultrasonographic appearance of the dorsal aspect of the DIP joint has been described, 16 and little or no fluid is present in the dorsal recess in clinically normal horses. However, measurements of the dorsal recess were not provided.…”

Comparison between palpation and ultrasonography for evaluation of experimentally induced effusion in the distal interphalangeal joint of horses

Although palpation provided a reliable clinical assessment of DIP joint effusion for volumes of 4 to 10 mL, ultrasonographic measurements were easy to obtain, more accurate, and able to detect smaller amounts of distension. This may be clinically relevant for the assessment of effusion of the DIP joint that can arise in horses with early osteoarthritis or infectious arthritis with concomitant soft tissue swelling that precludes accurate assessment with palpation.
