Canine Hip Dysplasia

The progression of hip dysplasia was investigated in 116 military working dogs. Serial pelvic radiographs were graded for degree of dysplasia and degenerative joint disease (DJD). Norberg angles, angles of inclination, and joint space widths were measured. There was a significant correlation between the Norberg angle and the degree of dysplasia (p less than 0.0001). Angles of inclination and joint space width measurements did not demonstrate a correlation to canine hip dysplasia. Dysplastic dogs had a significant estimated risk for development of DJD compared to normal dogs (p less than 0.0001; odds ratio of 70.2). Dogs with normal hip conformation at 24 months of age or older did not develop moderate nor severe DJD.

In this study, triple pelvic osteotomy (TPO) was carried out in a total of 22 dysplastic dogs, of which 9 were treated bilaterally and 13 unilaterally, and the position of the acetabulum was changed in a total of 31 hip joints using a special plate. It was established that, of the treated hip joints, 16 had severe, 12 medium and 3 mild dysplasia, the Norberg angle was between 70–92° and that the covering rate of the acetabulum over the femoral head changed between 5–42°. In the radiographs taken immediately after the operation, the covering rate of the acetabulum over the femoral head was determined to be very good in 25 hip joints (75% and over) and good in 6 joints (60–75%). In 5 cases, some of the screws holding the plate in place were seen to loosen in radiographs. However, this did not have any effect on the angle given to the acetabulum. In radiographs obtained 6–48 months later, degenerative joint disease was not encountered in 29 cases, with the exception of 2 cases. It was concluded that hip dysplasia, which is a hereditary disease, can be treated reasonably successfully in young dogs with TPO carried out before degenerative changes begin to occur in the joint.

ABSTRACT We evaluated 160 hip joint radiographs of 40 dogs of different large breeds (25 females and 15 males) from the metropolitan area of Belo Horizonte, Minas Gerais, Brazil. The radiographs of each dog were obtained at two different stages: stage 1 (mean 7.23 months) and stage 2 (mean 14.25). The conventional radiographic method (CRM) and the radiographic distraction method (RDM) were used, carried out in both stages. CRM measured the Norberg angle (NA), the angle of inclination (AI) and evaluated the presence of degenerative joint disease (DJD). The MRD was performed to establish the distraction index (DI). The aims were to evaluate the presence of the Morgan line and other signs of DJD and correlate them with the degree of canine hip dysplasia (CHD) and also check if the DI greater than 0.3 (first stage) was associated with the presence of ML (second stage). It was found that DI, AI and changes of femoral neck and the formation of osteophytes were associated with the presence of ML. It was observed that if the DI is greater than 0.3 at the first stage, the chance of a positive outcome of ML in the second stage increases by 7.2 times. Thus, 49 joints showed DI > 0.3 at the first stage, in which 31 (63.3 %) presented ML at the second stage. Of the 31 animals that showed DI ≤ 0.3 at first, six (19.4%) had LM at the second stage. There has been a significant association between the presence of ML and the degree of CHD. The more severe the CHD, the higher the percentage of positive ML results. Thus, among the 24 (60 %) animals that showed ML, 11 (45.83 %) were classified as severe dysplastics, 5 (20.83%) as moderate and 8 (33.33 %) as mild. None of the animals classified as normal or borderline presented ML. Among the 8 animals classified as mild dysplastics, 5 showed only ML as DJD.

Hip joint laxity was evaluated in four breeds (i.e., greyhound, Labrador retriever, Irish setter, hound mixed-breed) of puppies (n=32) by Ortolani's and Bardens' maneuvers, by subjective assessment of radiographs (Orthopedic Foundation for Animals [OFA] method), and by four radiographic measurement indices. Puppies were studied at four, six-to-10, 16-to-18, and 52 weeks of age. The purpose of this study was to compare palpation and radiographic methods of hip laxity detection in puppies for predicting the development of degenerative joint disease (DJD) by one year of age. Twenty-seven (42%) hips developed DJD. Ortolani's method was not a reliable predictor of hip dysplasia at six-to-10 weeks; it was significantly predictive at 16-to-18 weeks but had a high incidence of false negatives. Bardens' and subjective (OFA) assessment methods were not reliable at six-to-10 or 16-to-18 weeks. Radiographic measurements taken with femurs in a neutral position and hips distracted (distraction index [DI] and Norberg angle) and measurements taken with femurs extended in OFA position (Norberg angle) of six- to 10-week-old puppies accurately predicted DJD occurrence by one year of age (p less than 0.01). Distraction index measurement (PennHIP method) was the most accurate in predicting the development of DJD (p less than 0.001). Distraction index radiography in puppies six-to-10 and 16-to-18 weeks of age was the most reliable predictor of hip dysplasia. Norberg angle measurement was more reliable during hip distraction than when hips were measured in the OFA position in 16- to 18-week-old puppies, but had similar reliability in six- to 10-week-old puppies.

SummaryTriple pelvic osteotomy (TPO) was used in the treatment for traumatic coxofemoral luxations in four adult, large breed dogs with hip dysplasia. Initial closed reductions failed in three and one dog had an initial closed reduction and subsequent open reduction of the coxofemoral luxation that failed. Hip dysplasia was thought to be a prominent factor contributing to the reluxation. TPO successfully maintained reduction of the coxofemoral luxation in all of the dogs. An increase in dorsal acetabular coverage of the femoral head following TPO was demonstrated by an increased Norberg angle. The improved congruency was thought to maintain reduction of the femoral head in the acetabulum and decrease stresses on the joint capsule, allowing healing to occur. Long-term (median: 343, mean ± SD: 406 ± 226 days follow-up) function of the affected limb was comparable to the contralateral limb. Three of the four dogs did not have radiographic progression of coxofemoral degenerative joint disease of the affected joint and differences in the progression of degenerative joint disease were not evident between the affected and the contralateral coxofemoral joint. A decrease in abduction and external rotation and an increase in internal rotation following TPO was noted in the affected coxofemoral joint. Our results establish the utility of this procedure in dysplastic dogs with traumatic coxofemoral luxations.Triple pelvic osteotomy used in the treatment for traumatic coxofemoral luxation in four adult, large breed dogs with hip dysplasia successfully maintained reduction and resulted in satisfactory limb function in all patients.

The Relationship

Osteoarthritis (OA) is a degenerative joint disease characterized by loss of articular cartilage, inflammation and pain, which sometimes necessitates total joint arthroplasty (TJA). Profiling biomarkers of cartilage degradation and inflammation is a promising area of research to understand the pathogenesis of OA. This study aims to report the post-operative fluctuations of 3 biomarkers of OA, osteopontin (OPN), matrix metalloproteinase-9 (MMP-9), and ADAMTS4 (a disintegrin and metalloproteinase with thrombospondin motifs 4), in patients undergoing TJA to further define the interaction among these biomarkers and delineate their role in OA pathogenesis. OPN is an extracellular matrix (ECM) glycoprotein with increased activity in OA and joint damage and is upregulated by either inflammation or cleavage by MMPs and thrombin. MMP-9 is known to cleave OPN and is upregulated by inflammatory markers, such as IL-1, IL-6 and CRP. ADAMTS4 is an enzyme that degrades aggrecan, a major component of cartilage. These biomarkers were measured in deidentified blood samples collected on the day of surgery, 1 day post-operatively, and day 5-7 post-operatively. MMP-9 and OPN levels were significantly elevated at all times, and ADAMTS4 was significantly decreased at baseline versus controls. OPN and ADAMTS4 inversely fluctuated post-operatively, indicating an interrelation between these 2 biomarkers. This study suggests that the upregulation of MMP-9 and therefore OPN then results in the downregulation of ADAMTS4. The relationship between OPN and thrombin also highlights the importance of monitoring for thrombotic complications. These biomarkers, along with thrombin-mediated cleavage products, may be helpful in the prognostic management of OA patients.
