Introduction/Purpose: Lifting the contralateral forelimb is often used as a method of restraint when obtaining forefeet radiographs in horses. This experimental study was conducted to evaluate the effect of unipodal vs bipodal stance on several radiographic parameters in equine forefeet. We hypothesized that unipodal stance would influence mediolateral and sagittal balance by reducing lateral distal interphalangeal joint (DIPJ) space width and increasing flexion of the distal interphalangeal joint (DIPJ). Methods: Four non-lame horses with normal foot conformation were randomly selected. Lateromedial (LM) and dorsopalmar (DP) projections were obtained on both forefeet, squarely placed on blocks, using 2 x-ray generators in a fixed position laterally and dorsally to the foot. Radiographs of each foot were made in a bipodal stance, immediately followed by the same protocol in an unipodal stance (after lifting the contralateral limb) without moving neither the foot nor the x-ray generator. Several measurements were made: DIPJ space width at particular landmarks on DP and LM projections; mediolateral joint balance on DP projections; deep digital flexor tendon (DDFT) angle to solar surface of the distal phalanx (P3) and distance between P3 extensor process and dorsoproximal extent of the middle phalangeal (P2) condyle as an indication of DIPJ flexion on LM projections. A matched pairs design and student’s t-test with a 95% confidence level were used to test for statistical significance. Results: Compared to a bipodal stance, lateral DIPJ space width was significantly reduced on unipodal DP views (-0.75mm[I assume this is the mean?]; CI ±0,35; p<0.005), whereas medial DIPJ space width and mediolateral joint imbalance were significantly increased (+0[These numbers are so small, that I would really like to know what the measurement error is. I am somewhat doubtful that these measurements are bigger than the error associated with repeatability of the measurment].40mm; CI ±0.18; p<0,005 resp +1,15mm; CI ±0.42; p<0.0005).[ Mean DIPJ space width reduction on unipodal DP views (-0,17mm; CI ±0,19; p<0,05), allthough statistically significant, was no longer taken into account as the confidence interval was as large as the main difference.] No statistical difference was observed in mean DIPJ space width on LM views between both conditions. The distance between the P3 extensor process and the dorsoproximal extent of P2 condyle, as well as the DDFT angle, were significantly increased in unipodal LM views (+1.98mm; CI ±0.83; p<0.0005 resp +10.54°; CI ±2.45; p<0,0005), indicating a higher degree of DIPJ flexion in that condition. Discussion/Conclusion: Unipodal stance significantly affects the mediolateral balance of the DIPJ on DP radiographs and significantly alters the phalangeal axis on LM radiographs. These findings suggest that stance should be carefully taken into consideration when radiographically evaluating equine forefeet, especially if assessing foot balance. [less ▲]

Introduction/Purpose Comparison learning is an approach for learning complex visual tasks. As described in human medicine, by comparing radiographs with pathology and without pathology, veterinary students could learn to discriminate relevant disease-related information to recognize the disease. We hypothesized that exposure to a training by side-by-side comparison of normal to abnormal radiographs would lead to higher visual diagnostic accuracy and possibly to a higher ability to describe the features of a known disease on canine thoracic radiographs. Material and methods Twenty veterinary students were randomly assigned to either a group that compared radiographs showing thoracic disease with normal images (group 1) or to a group that only studied abnormal radiographs (group 2). All students had their theoretical radiology teaching and 13 of them had also received the practical teaching of the study curriculum, evenly distributed between the 2 groups. Twenty-nine radiographs of small animal thorax were used. The procedure consisted in three experimenter-supervised phases: 1. training, 2. visual recognition test, 3. feature description test. In the training phase, each screen showed two radiographs with the name of the disease present in each. In the group 1 (pathology/normal condition), a radiograph of a patient and a normal image were shown next to each other. In the group 2 (pathology/pathology condition), two radiographs of patients with the same disease were shown next to each other. The 9 screens were presented twice, with the diseases in a different order for the first and second runs. A Mann-Whitney test was used to compare the success rates of groups of students. Results On visual recognition test, there was no statistical difference in visual diagnostic accuracy between groups. When students gave the wrong answer, they often diagnosed the item as another disease of similar distribution (diffuse or focal). Students who received the practical teaching and students of group 1 had a higher accuracy for normal thoracic radiographs. On feature description test, no significant effect of comparison learning was found, but focal diseases were better described than diffuse diseases with a significant difference between these. Discussion/Conclusions Results show that comparison with normal images did not help in recognizing or describing thoracic pathologies but helps to recognize normal images. [less ▲]

The standard technique for placing a needle into the canine lumbar subarachnoid space is primarily based on palpation of anatomic landmarks and use of probing movements of the needle, however, this technique can be challenging for novice operators. The aim of the current observational, prospective, ex vivo, feasibility study was to compare ultrasound-guided vs. standard anatomic landmark approaches for novices performing needle placement into the lumbar subarachnoid space using dog cadavers. Eight experienced operators validated the canine cadaver model as usable for training landmark and ultrasound-guided needle placement into the lumbar subarachnoid space based on realistic anatomy and tissue consistency. With informed consent, 67 final year veterinary students were prospectively enrolled in the study. Students had no prior experience in needle placement into the lumbar subarachnoid space or use of ultrasound. Each student received a short theoretical training about each technique before the trial and then attempted blind landmark-guided and ultrasound-guided techniques on randomized canine cadavers. After having performed both procedures, the operators completed a self-evaluation questionnaire about their performance and self-confidence. Total success rates for students were 48% and 77% for the landmark- and ultrasound-guided techniques, respectively. Ultrasound guidance significantly increased total success rate when compared to the landmark-guided technique and significantly reduced the number of attempts. With ultrasound guidance self-confidence was improved, without bringing any significant change in duration of the needle placement procedure. Findings indicated that use of ultrasound guidance and cadavers are feasible methods for training novice operators in needle placement into the canine lumbar subarachnoid space. [less ▲]

RÉSUMÉ : Le placement échoguidé de l’aiguille spinale pour les ponctions cisternale et lombaire chez le chien a été décrit. L’objectif de ce travail était de comparer l’effet du guidage échographique pour la ponction de liquide céphalo-rachidien entre les ponctions cisternale et lombaire. Quatre-vingt-trois opérateurs ont participé à l’étude. Ils étaient divisés en quatre groupes selon leur expérience. Après une formation théorique courte, chaque opérateur a réalisé une ponction cisternale et lombaire en aveugle et sous contrôle échographique sur des cadavres tirés au sort. L’échoguidage lombaire était direct alors que celui cisternal était indirect. Après chaque procédure, les opérateurs ont rempli un questionnaire sur leur expérience, leur performance et leur confiance en soi. L’échoguidage augmentait significativement le taux de réussite global de la ponction (comparée à la méthode en aveugle) mais plus clairement avec la localisation lombaire. Le guidage échographique cisternal améliorait significativement le nombre de tentatives, le temps et la confiance en soi chez les opérateurs inexpérimentés et expérimentés. La première cause d’échec citée était différente selon la localisation de la ponction et était liée à la nature de l’échoguidage. Cette étude démontre que les opérateurs inexpérimentés sont capables de réaliser des ponctions échoguidées après une formation théorique courte, justifiant l’utilité du guidage échographique à des fins pédagogiques.

Epidural injections are commonly performed blindly in veterinary medicine. The aims of this study were to describe the lumbosacral ultrasonographic anatomy and to assess the feasibility of an ultrasound-guided epidural injection technique in dogs. A cross sectional anatomic atlas of the lumbosacral region and ex vivo ultrasound images were obtained in two cadavers to describe the ultrasound anatomy and to identify the landmarks. Sixteen normal weight canine cadavers were used to establish two variations of the technique for direct ultrasound-guided injection, using spinal needles or epidural catheters. The technique was finally performed in two normal weight cadavers, in two overweight cadavers and in five live dogs with radiographic abnormalities resulting of the lumbosacral spine. Contrast medium was injected and CT was used to assess the success of the injection. The anatomic landmarks to carry out the procedure were the seventh lumbar vertebra, the iliac wings, and the first sacral vertebra. The target for directing the needle was the trapezoid-shaped echogenic zone between the contiguous articular facets of the lumbosacral vertebral canal visualized in a parasagittal plane. The spinal needle or epidural catheter was inserted in a 45° craniodorsal-caudoventral direction through the subcutaneous tissue and the interarcuate ligament until reaching the epidural space. CT examination confirmed the presence of contrast medium in the epidural space in 25/25 dogs, although a variable contamination of the subarachnoid space was also noted. Findings indicated that this ultrasound-guided epidural injection technique is feasible for normal weight and overweight dogs, with and without radiographic abnormalities of the spine. [less ▲]
