“…In human medicine, using standard terminology and reference ranges of the intact skeletal structure is common, and different methods are developed, which allows physicians to differentiate normal and pathologic limb conformation [9]. As in human medicine, standard terminology and measurements have been developed in veterinary medicine [10–17].…”

Femoral and tibial alignments in chihuahuas with patellar luxation by radiograph: Angular values and intra- and inter-observer agreement of measurements

et al. 2019

Measurement of fore and pelvic limb alignment in veterinary orthopedics is significant, as it is in human medicine. The establishment of reference ranges for alignments and comparing measured ranges in diseased animals to these reference values would allow veterinarians to specify the quantitative degree of an angular deformity, plan suitable treatments and evaluate treatment outcomes. Patellar luxation is a common orthopedic disease in small animal clinics. Severe grades of MPL may present with bone deformities or abnormal alignments; therefore, evaluation of the measurement methods of femoral and tibial alignment in dogs with different grades of patellar luxation to assess the accuracy and reliability of the measurements could be useful. In this retrospective study radiographs of 21 client-owned Chihuahuas that had been presented to the Small Animal Surgery of Vetmeduni Vienna from 2012–2016 with a diagnose of patellar luxation were selected. The measurements were performed on frontal, lateral and axial view radiographs to determine the femoral and tibial angles and to evaluate the intra- and inter-observer variabilities of the protocol. Radiographs of each dog were investigated by three observers. Intra-observer variability was based on measurements by each observer who repeated the protocol two times to evaluate repeatability. Inter-observer variability was based on the measurements between the three observers to evaluate the reproducibility of the protocol. The results of the study showed that 92.85% of inter-observer ICC (intra-class correlation coefficient) had high correlation, and the remaining 7.15% had good correlation. Intra-observer ICCs for measurements of the first observer were 28.57% high correlation and 50% good correlation. For the second observer, 100% high correlation was recorded, and for the third observer 71.42% high correlation and 14.28% good correlation was recorded. These results show that the selected methods have high correlation and could be used as a reliable method in veterinary orthopedics.

“…Cranial cruciate ligament rupture (CCLR) is the orthopedic knee condition most common in dogs (Calvo et al 2014 ; Marino and Loughin 2010 ). The causes that lead to CCLR are still not completely defined (Vedrine et al 2013 ), but a number of presumed factors lead to a common pathway in the origin of these lesions (Cook 2010 ). Although the lesions are primarily traumatic, other degenerative factors have been noted in the pathogenesis of this condition, such as age, sex, and obesity (Venzin et al 2004 ), as well as racial predisposition, inflammatory and conformation alterations, and immune-mediated mechanisms (Griffon 2010 ).…”

BackgroundThe cranial cruciate ligament rupture (CCLR) is the most commonly encountered orthopedic condition in dogs. Among the various techniques to treat this condition, tibial tuberosity advancement (TTA) has been used to obtain rapid recovery of the affected knee. The objective of this study was to evaluate the viability of the use of mesenchymal stem cells (MSC) implanted in the osteotomy site obtained by TTA in nine dogs diagnosed with CCLR.MethodsThe MSC were isolated from the adipose tissue of the dogs and cultured for eight days, the animals were divided into two groups. Animals from the treated group (GT) received cell transport medium containing about 1.5 millions MSC, and the animals from the control group (GC) received only the cell transport medium. The study was performed in a double-blind manner using radiographs acquired on days 15, 30, 60 and 120 after the procedure. Evaluations of the density of the trabecular bone were performed using image analysis software. The results were subjected to descriptive statistical analysis, followed by the normality test, Chi-square test, Mann-Whitney test and Tukey’s multiple comparison test for p ≤ 0.05.ResultsAfter 30 days of the procedure, the animals of the GT presented an ossification mean 36.45% greater (p ≤ 0.033) than the GC, and there were no statistical differences for the other periods.ConclusionsDespite the total bone ossification within the expected period, there was no minimization of the estimated recovery time with the application of MSC, and inflammatory factors should be considered for reassessment of the therapeutic intervention time.

The tibial plateau angle measurement and its applicability have been reviewed based on the literature. The measurement was made on radiographs of the stifle joint with superimposition of the femoral condyles (with maximum tolerance of 2.0-4.0mm). Due to great variation among dog populations (size, breed), mean tibial plateau angles were found to be between 16.9° and 34°, but an excessive angle was described as >35°. An appropriate measurement of the tibial plateau angle can be made at about 108 days of age. The influence on the magnitude of the measured tibial plateau angle were the limb position during radiographic examination, the measurement technique (with modifications) and the experience level of the observer. Differences in magnitudes of the tibial plateau angles in dogs with and without cranial cruciate ligament rupture were not observed. The tibial plateau angle is commonly used in osteotomy of the tibia and its magnitude in order to select the proper surgical technique. The significance of the tibial plateau angle on the aetiopathogenesis of cranial cruciate ligament disease is questionable. Other measurements of the proximal tibia were attained to determine the risk factor of cranial cruciate ligament insufficiency. Knowledge of the tibial plateau angle and factors influencing measurement errors have great clinical importance.
