Canine Hip Dysplasia

Abstract Canine hip dysplasia (CHD) is a common disease representing an important problem for many dog breeds worldwide. The screening for CHD and breeding programs have been ongoing for many decades but the incidence of disease have failed to be reduced to the expected level. The early diagnosis of CHD is paramount in order to facilitate the early management strategies and to prevent the breeding of the affected individuals. Generally in this area, the emphasis is placed on the radiographic evaluation process, however this is partly a subjective process suggested to be influenced by the experience of the observers. This study was designed to evaluate the interobserver agreement in CHD evaluation based on the Federation Cynologique International system (FCI system). Ten original radiographs were sent to five different groups of observers, from students to certified veterinarians. They were asked to evaluate the ventro-dorsal radiographs according to the FCI system which is the most common system used in Europe to give the final grades (A, B, C, D, E). The grades were converted to numbers and the data were analysed using a one-way ANOVA test. The results showed that only in 20% of the cases, the interobserver agreement was statistically higher in the group of the most experienced observers when compared to the less experienced group of observers. This means that the level of experience does not always lead to a higher agreement. This could be a problem of widespread objective evaluations of CHD. In addition, there are several different systems of evaluation used in various countries. It is necessary to understand the intention of dog owners, who when buying a dog may be planning its first breeding. Therefore, the “correct” or “incorrect” assessment of the CHD radiographs may not always result in the elimination of affected individuals. We do not know exactly the situation of the development of the hip in some breeds, because scrutineers are receiving only “negative radiographs” for evaluation. Many owners are very educated about hip and elbow dysplasia. It is a time to tell the scientific truth.

Abstract Background Canine hip dysplasia (CHD) is a common disease, with a complex genetic background. Dogs with severe CHD sometimes also suffer from osteoarthritis (OA), an inflammatory, often painful and incurable condition. Previous studies have reported breed-specific genetic loci associated with different hip dysplasia and OA phenotypes. However, the independent replication of the known associations within or across breeds has been difficult due to variable phenotype measures, inadequate sample sizes and the existence of population specific variants. Results We execute a validation study of 46 genetic markers in a cohort of nearly 1600 dogs from ten different breeds. We categorize the dogs into cases and controls according to the hip scoring system defined by the Fédération Cynologique Internationale (FCI). We validate 21 different loci associated on fourteen chromosomes. Twenty of these associated with CHD in specific breeds, whereas one locus is unique to the across-breed study. We show that genes involved in the neddylation pathway are enriched among the genes in the validated loci. Neddylation contributes to many cellular functions including inflammation. Conclusions Our study successfully replicates many loci and highlights the complex genetic architecture of CHD. Further characterisation of the associated loci could reveal CHD-relevant genes and pathways for improved understanding of the disease pathogenesis.

ABSTRACT: The purpose of this study was to describe our initial experience with double pelvic osteotomy (DPO) in young dogs affected by hip dysplasia (HD) and to report their postoperative outcome. Seven dogs (four females and three males) were included in our study with mean age 8.3 (±1.7) months, and mean body weight 29.5 (±7.4)Kg. Breeds involved were: Rottweiler (n = 1), Labrador Retriever (n = 3), Golden Retriever (n = 1), Great Dane (n=1) and São Miguel Cattle Dog (n = 1). The most common history complaints were: pelvic limb lameness and pain at hip extension and hip abduction. All surgical procedures consisted of osteotomy of the ilium and pubis, acetabular ventroversion and iliac stabilization with a customized bone plate with seven screws, four screws placed at the cranial fragment and the remaining three in the caudal aspect. Average surgical time was 65.8 (±10.4) minutes and median follow-up assessment was 68 (±15) days. Fracture healing was observed within mean period of 26.3 (±8.9) days. Six patients (86%) had satisfactory outcome and one patient didn’t improve after surgery and had to undergo a total hip replacement. Our results showed that DPO is an effective treatment for HD due to the preservation of pelvic geometry and low postoperative morbidity. Since it is a recent technique, further studies are recommended.

SummaryTriple pelvic osteotomy (TPO), as a treatment for canine hip dysplasia, was evaluated radiographically in 38 cases. Several parameters on radio-graphs of the pelvis, taken pre- and postoperatively, as well as six weeks and three months after the operation, were measured and compared. The results were also compared between iliac osteotomy fixation with the canine pelvic osteotomy plate (CPOP, n = 16) and the twisted dynamic compression plate (DCP, n = 22). Acetabular support (from 0.21 to 0.89), Norberg angle (from 77.6° to 111.8°) and hip joint congruence improved significantly after TPO. Dorsal pelvic width did not change, whereas, due to rotation, ventral pelvic width decreased to 80% of its pre-operative value. Osteophyte formation was judged to be moderate three months after the operation. Comparison of the two plating methods showed significant postoperative advantages for the CPO P group in terms of a higher Norberg angle and a better congruence. There was some loosening of 33% of the screws in both groups, but this did not interfere with the aim of the TP O procedure.The effect of triple pelvic osteotomy, as a treatment for canine hip dysplasia, was investigated retrospectively by means of radiographs. Acetabular support, the Norberg angle, and hip joint congruence improved significantly after the operation. Iliac osteotomy fixation, with the canine pelvic osteotomy plate, displayed advantages over the twisted dynamic compression plate. Screw loosening occurred frequently but without any major consequences.

Objectives Comparison of PennHIP and a novel method to diagnose hip laxity, called the Vezzoni modified Badertscher distension device technique. Methods In a total of 10 dogs, it was first assessed whether the distraction index (DI) from the PennHIP evaluation center could be reproduced by two individual observers. In the next two steps, the DI measurements made by the individual observers and the PennHIP evaluation center were compared with the laxity index (LI) measured on the Vezzoni modified Badertscher distension device view. Finally, the interobserver agreement of the DI, LI and Norberg angle was assessed and compared with classification criteria. Results The results were similar for the first three comparisons: there was no evidence for bias, the relation between DI and LI was linear and the variability was small. A comparison of the interobserver agreement showed that the measurement variability for the NA was substantial, while the reproducibility for the DI and LI was equal. Clinical Significance While the standard ventrodorsal hip extended radiograph is most commonly used for diagnosis and screening of canine hip dysplasia, it lacks sensitivity to diagnose laxity. To improve the identification of hip joint laxity, distraction-based radiographic techniques are helpful. The Vezzoni modified Badertscher distension device technique allows for a reliable in-house evaluation of canine hip joint laxity.

SummaryTreatment of canine hip dysplasia (CHD) via triple pelvic osteotomy (TPO) is widely accepted as the treatment that best preserves the existing hip joint. TPO, however, has several important disadvantages. In an effort to avoid some of the difficulties associated with TPO an alternative method of creating acetabular ventroversion (AW) was sought. The purpose of this study was to explore the effects of placement of a wedge in the sacroiliac (SI) joint on A W and to compare this to the effect of TPO on A W . On one hemipelvis a 30° pelvic osteotomy plate was used for TPO. The contralateral hemipelvis had a 28° SI wedge inserted into the SI joint. Pre- and postsurgical radiographs of each pelvis were taken and the angular measurements were recorded. On average, the 28° SI wedge resulted in 20.9° of A W, the 30° canine pelvic osteotomy plate resulted in 24.9° A W . Significant differences were not found (p >0.05) between the two techniques. Sacroiliac wedge rotation effectively creates A W and has several theoretical advantages when compared to TPO. The in vivo effects of sacroiliac wedge rotation should be studied in order to evaluate the clinical effect of the technique.Sacroiliac wedge rotation was tested as an alternative method to increase the angle of acetabular ventroversion. This technique effectively rotated the acetabulum and has several theoretical advantages when compared to triple pelvic osteotomy.
