Establishing the osteoarticular status of the horse is often performed by means of radiological screening of the animals. Widespread blood sampling could potentially be an alternative to this procedure which is time consuming and sometimes technically difficult. The aim of this study was to investigate the relationship between the radiological status of the horses and the levels of biochemical markers (BM) of cartilage degradation and synovial inflammation. Materials and Methods: A specific radiological scoring (RS) system was developed and applied on 63 stallions presented for studbook admission. Additionally, groups of horses were established according to the occurrence of osteochondrosis (OC), degenerative joint disease (DJD) and distal interphalangeal joint (DIPJ) effusion. Insulin growth factor-I, myeloperoxidases, Coll2-1 and Coll2-1NO2 were used as BM. The effects of age and weight on the BM and of the BM on the RS were measured. Mean values of BM between OC positive versus negative, DJD positive versus negative and DIPJ effusion positive versus negative were compared using SAS statistical program. Results: No effect of the combined BM was found on the RS. No significant differences between the values of the BM were found within the different radiological classes (RC). However, considering only the Coll2-1NO2 marker, the probability to belong to class A was given by the equation 9.63 -0.31 Coll2-1NO2 + 0.04 (Coll2-1NO2)². Equally a tendency (p= 0.06) towards an increase in RC by 0.45 for each increasing unit of Coll2-1NO2 was present. Significant positive correlations were found between Coll2-1 values and Coll2-1 NO2 values. MPO values were found to be significantly higher in OC negative horses (357.86  64.43 ng/ml) than in OC positive horses (231.17  27.15 ng/ml). IGF-I levels were found significantly lower in the positive DIPJ effusion group (416.05  17.57 ng/ml) compared to the negative DIPJ effusion group (477.1  22.40 ng/ml). Coll2-1 values were significantly higher in the positive DIPJ effusion group (911.04  41.13 nM) compared to the negative DIPJ effusion group (769.04  37.92 nM). Mean values of Coll2-1 were significantly higher in the DJD positive group (901.24  36.75 nM) compared to the DJD negative group (790.590  39.397 nM) Discussion: The combination of the blood parameters did not seem to correlate with the used RS system. Coll2-1NO2 levels however tend to increase with poorer RC and could therefore be used as a useful predictor of the osteoarticular status of the horse. Coll2-1 levels were significantly higher in the degenerative joint disease group. A high percentage of horses with DIPJ effusion was present in this study and was associated with decreased IGF-I and increased Coll2-1 levels. [less ▲]

Developmental osteochondral lesions are often encountered in the equine population and are a major cause of lameness. Different growth factors that act systemically as well as locally regulate the growth of cartilage. Among them is Insulin-like Growth Factor I that has been demonstrated to promote chondrocyte growth and differentiation and that has been shown to influence cartilage repair. The aims of this study were to investigate differences in circulating plasma levels of Insulin-like Growth Factor-I in post-pubescent horses affected with developmental osteochondral lesions compared to unaffected ones. Significantly higher values of circulating Insulin-like Growth Factor-I levels were found in the affected group (n = 82) compared to controls (n = 86). This result may still reflect an earlier imbalance in IGF-I levels from horses with developmental osteochondral lesions considering the aetiopathological link which has been made between IGF-I and the occurrence of osteochondrosis. However, other studies have shown increased expression of IGF-I after cartilage damage. The higher levels found in this study could be due to a healing response of the cartilage to the damage caused by the osteochondral lesions. [less ▲]

The purpose of this work was to establish one or several short protocols for magnetic resonance imaging of the equine cadaver foot, using the most appropriated sequences in a limited number of planes, allowing the assessment of the anatomical structures. Three feet were scanned with most of the sequences used for evaluation of the osteo-articular system in seven different ection planes (1 sagittal, 3 dorsal and 3 transverse planes). The sequences and the planes in which the anatomical structures were best assessed were selected by scoring the visualization of the anatomical structures. Three short protocols are proposed. The first protocol uses spin echo sequences, one fat suppressed sequence and one sequence to evaluate the cartilage. The second adds gradient echo sequences to show the sites of haemorrhage and the articular cartilage. The third protocol adds special section planes, the first perpendicular to the distal insertion of the deep digital flexor tendon and the second perpendicular to the collateral ligaments of the distal interphalangeal joint and adds another sequence combining cartilage visualization and fat suppression.

Several molecules available in equine medicine provide profound sedation and good analgesia when performing diagnostic or surgical procedures. They differ slightly in degree of action, as well in time as in depth. The aim of this study was to evaluate the depth of sedation and quality of performing a standardized procedure after injection of an 2-agonist alone or associated with butorphanol. Horses presented to the Equine Clinic of Liege University from December 2007 to June 2008 for an endoscopic, dental, radiological or ophthalmological examination of which owner and clinician agreed to include the horse in the study were retained. All horses (n=133) were sedated in a randomized double blind fashion using one of the six following protocols: detomidine (D) (0.01mg/kg IV), romifidine (R) (0.04mg/kg IV), or xylazine (X) (0.5mg/kg IV) alone or associated with butorphanol (B) (0.02mg/kg IV). Stability, head position and the reaction to a stimulus (auditive and visual) were evaluated before the start of the procedure. An overall subjective grade using a 10 cm line scale was given to evaluate sedation depth (ranging from no effect to maximal depth on line) and the quality of the performed procedure (ranging from not realised to ideal examination). For each specific procedure, the same clinician experienced in his particular field evaluated the parameters. Data were related by a variance analysis using SAS system and considered significant if P<0.01. The used protocols significantly influenced both sedation depth and examination quality. Sedation depth increased significantly when B was added in all the three 2-agonists used (mean ± SD): D: 6.46±0.33; D+B: 7.06±0.37; R: 4.93±0.46; R+B: 7.04±0.45; X: 4.94±0.43; X+B: 7.75±0.40. Detomidine provided a significantly better quality of the examination compared to romifidine and xylazine. The addiction of butorphanol significantly decreased the examination quality when added to detomidine and increased the quality when combined with romifidine and xylazine. Mean (± SD) of the quality of performed procedures: D: 8.41±0.54; D+B: 6.06±0.64; R: 6.68±0.71; R+B: 7.16±0.67; X: 4.47±0.67; X+B: 4.52±0.64. Comparison of sedation depth and quality of performed examination revealed an increase in quality of examination scores with increasing depth of sedation until a certain level. As from sedation depths with scores of 8 or more, a decrease in quality of examination was encountered. This report shows the important effect of butorphanol addition on sedation. However, increasing sedation depth was not necessarily linked to a better quality of procedure, notably due to difficulties in handling strongly sedated horses for the procedures performed in this study.
