“…The dose of 30 mg of lidocaine was able to improve lameness in only 77%; this is consistent with what has been previously reported in another studies [15,16] used for determination of unequivocal decrease in severity of lameness after blocking a cutoff value of 70% improvement in the objective lameness parameter of VS of HDmax and HDmin.…”

“…This method of lameness induction yields a reversible lameness in horses and does not result in complications. Rungsri et al [15] showed that the improvement of lameness after a distal interphalangeal joint block was greater after 5 and 10 minutes than after 2 minutes of intraarticular injection of 5 mL of mepivacaine. Considering the finding of Rungsri et al, the analysis started at 5 minutes after PD block because local anesthetics would have better distribution and early clinical significant effect.…”

“…Nine adult horses were randomly allocated in a crossover design (bupivacaine, 5 mg/mL; lidocaine, 20 mg/mL; and ropivacaine, 7.5 mg/mL). The objective lameness evaluations were recorded before and at 5, 10,15, 30, 60, 90, 120, 150, 180, 210, 240, and 300 minutes after PD block. The relative lameness severity (RLS) was determined and analyzed using the Tukey-Kramer test (P < .05).…”

a b s t r a c tThe aim of the present study was to determine the duration and efficacy of three local anesthetics in the palmar digital (PD) nerve block. Nine adult horses were randomly allocated in a crossover design (bupivacaine, 5 mg/mL; lidocaine, 20 mg/mL; and ropivacaine, 7.5 mg/mL). The objective lameness evaluations were recorded before and at 5, 10,15, 30, 60, 90, 120, 150, 180, 210, 240, and 300 minutes after PD block. The relative lameness severity (RLS) was determined and analyzed using the Tukey-Kramer test (P < .05). Lameness improvement (LI) after blocking was determined as a percentage decrease in the quadratic mean (vector sum). The RLS after lameness induction was 4.06 times the threshold (8.5 mm), and the intensity of lameness (time 0) was similar between horses (coefficient of variance ¼ 25%). Five minutes after PD block, all drugs had improved lameness in more than 2.5 times (LI >60%). Bupivacaine, lidocaine, and ropivacaine were effective in blocking at least three times (LI >75%) the experimental lameness. Using 7.5-mg bupivacaine, LI was >3.5 times between 5 and 90 minutes after PD block (LI >83%). With lidocaine (30 mg), between 5 and 90 minutes after blocking a significant LI was observed with a reduction in the lameness intensity greater than 1.2 times (LI >43%). Ropivacaine (11.25 mg) improved lameness in >2.6 times (LI >66%) between 5 and 180 minutes after block. Bupivacaine and ropivacaine showed greater anesthetic effectiveness when compared with lidocaine. The local anesthetics produced a significant LI 5 minutes after blocking. Objective analysis showed a longer analgesic effect of the PD nerve block using ropivacaine than bupivacaine and lidocaine, respectively.

“…Several studies have been conducted previously with these body-mounted inertial sensors for evaluation of flexion tests, the effect of anesthetic drugs, but no study has been performed to analyze whether ground surface has an influence on the lameness exam results (Marshall et al, 2012;Azevedo et al, 2014;Rungsri et al, 2014). The first objective was to verify if the inertial sensors could detect a significant change when animals were evaluated on three different ground surfaces and if different sequences of surfaces on which horses are examined could have an effect on the results.…”

This study aimed to evaluate the influence of the track surface on which horses are examined, regarding the phase of lameness presentation. Ten horses with lameness in at least one limb were evaluated with wireless inertial sensors on three track surfaces (concrete, loose sand and grass). Six crossover track sequences were established. The variables vector sum, maximum and minimum height of the head and pelvis, variation coefficient of the maximum and minimum height of the head and pelvis were analyzed using ANOVA, followed by Tukey test to compare means between track surface and sequence, at 5% significance level. The lameness phase (impact or pushoff) was analyzed considering the proportion of affected animals. There were no differences on vector sum, maximum and minimum height or variation coefficient of head and pelvis. Difference was observed on the number of strides registered on sand compared to grass and concrete (p <0.0001) for fore and hindlimbs. Impact lameness on forelimbs was presented by a larger number of animals on the concrete surface; pushoff lameness was more evident on the grass surface. In the hindlimbs, impact lameness was more evident on the grass surface, while pushoff lameness was in greater number of animals on concrete surfaces. The track sequence on which horses were trotted during evaluation does not seem to be a factor, but the number of lame horses and the phase of lameness manifestation can vary between track surfaces, as some horses showed impact lameness on soft ground and elevation lameness on hard ground.Keywords: horse, impact lameness, lameness locator, objective evaluation, push-off lameness RESUMO Este estudo teve como objetivo avaliar a influência do tipo de superfície em que os cavalos são examinados em relação à fase de apresentação da claudicação.

“…Die Hufgelenksanäs-thesie ist nur von diagnostischem Wert, wenn der Effekt innerhalb von fünf bis zehn Minuten beurteilt wird. Bei längerer Wartezeit diffundiert das Lokalanästhetikum ins umliegende Gewebe (Schumacher et al 2013, Rungsri et al 2014. In der Vergangenheit wurde zusätzlich eine Hufgelenksdruckmessung durchgeführt (Hertsch und Höppner 1999), die diagnostische Aussagekraft wurde jedoch nicht validiert.…”

The expected clinical results of the treatment with autologous conditioned serum (ACS) used on horses with osteoarthritis (OA) are based mainly on studies from the field of human medicine. These studies documented an effect lasting up to two years after therapy. The aim of the underlying study was to investigate the long-term outcome of horses with OA of the coffin joint that are exclusively treated with ACS. For this purpose, the medical records of horses whose coffin joint was treated with ACS between January 2007 and June 2010 were analysed. X-ray and MRI scans were re-evaluated. The coffin joint was only diagnosed with osteoarthritis if the coffin joint anesthesia reduced lameness by at least 50 % or if the block anesthesia delimited the lameness to the hoof area and the OA was clearly confirmed through diagnostic imaging. The long-term outcome was determined through telephone interviews with the owners. After a period of at least two years following the ACS treatment of the coffin joint, eight out of 26 horses (31%) returned to work at a level equal to or greater than their previous performance level and four (15 %) returned to work at a lower level. In the case of 14 horses (54 %), no long-term treatment success could be observed. No significant correlation between the severity level of the OA and the therapy results could be proven.Keywords: horse / osteoarthritis / coffin joint / diagnostic techniques / medical treatment / ACS / autologous conditioned serum
