“…Passive hip laxity (PHL) is the primary risk factor for the development of degenerative joint disease in dogs with hip dysplasia (Smith et al, 1995), and has been the support of research in new radiographic diagnostic techniques (Smith et al, 1990;Farese et al, 1998;Flückiger et al, 1999;Vezzoni et al, 2005). The most widely known, very well investigated and accepted technique for PHL measurement in dogs is a stress-radiographic method, denominated PennHIP (Ginja et al, 2006).…”

Two hundred and fifteen Estrela Mountain Dogs (EMD) were examined using the PennHIP method between 2002 and 2006. Passive hip laxity (PHL) was estimated calculating the distraction index (DI). Pedigree information was obtained from the Portuguese Kennel Club. The heritability and breeding values were estimated using the linear Animal Model. The DI, using as reference the worst joint of each animal, ranged from 0.15 to 1.12 (0.55 ± 0.19). The PHL was equal in right and left sides, and was higher in females than in males (P > 0.05 and P < 0.01 in the t-test, respectively). The estimated heritability was 0.83 ± 0.11. The mean breeding values for PHL were stable in EMD born between 1991 and 2003, and showed an improvement in 2004 and 2005. The data confirm high PHL in breeds with high prevalence and severity of canine hip dysplasia. The high heritability indicates that the DI could be reduced in the breed if PHL were used as a selection criterion. The early favourable evolution of DI breeding values could be related with the increase of voluntary radiographic hip screening in the last years, and the subsequent introduction of hip quality as a breeding criterion.

“…Quantitative measures of passive hip joint laxity such as the Norberg angle and distractive index derived from newer stress-radiographic diagnostic methods are also often used 4,22,23 . More recent diagnostic techniques include a dorsolateral subluxation test using radiography 7,8,16,17 , dynamic ultra-sonography 1 , computed tomography 8 and morphometric assessment of the canine hip joint using the dorsal acetabular rim view and the centre-edge angle 19 . A semiquantitative radiographic method of postoperative evaluation of traumatic hip dislocation was described in dogs 6 .…”

Ventrodorsal pelvic radiographs were made of 32 adult dogs under general anaesthesia. The hip joints were evaluated according to the severity of osteoarthritic changes graded as 0, 1, 2 or 3. The dogs were euthanased, the hip joints opened and the ligamentum capitis femoris dissected out in toto. The volume of each ligament was determined using a water displacement technique and the mean volume compared to the four radiographic grades of osteoarthritis. There was an inverse correlation (r = -0.75) between the mean volume of the ligamentum capitis femoris and the increasing severity of osteoarthritis as assessed by radiography. The results confirmed the crucial role of radiography in the clinical evaluation of hip dysplasia and osteoarthritis in the adult dog. Assessment of the volume of the ligamentum capitis femoris revealed that it is an important tool for research in canine hip dysplasia and osteoarthritis

“…Since in this method, dogs under general anesthesia are held in the standing position without excessive extension or flexion of the hindlimbs on the imaging platform, abnormal tensioning or twisting is not induced in the joint capsule. Therefore, the degree of joint laxity between the femoral head and acetabulum can be accurately evaluated [4,9,14]. Although further studies may be necessary to fully understand the phenomena observed in this study, they might be due to the formation of joint-supporting tissues such as periarticular fibrosis and the reinforcement of the supporting tissues around the hip joint with growing.…”

ABSTRACT. Changes in hip joint congruity was evaluated in dogs with hip dysplasia before and after triple pelvic osteotomy by computed tomography examination in the standing position. Lateral center edge angle significantly increased, and center distance (CD) significantly decreased after surgery compared to the values before surgery, respectively. There was an inverse proportion between the postoperative period and the change in the ratio of CD. These results suggested that joint laxity was improved with time after surgery, providing evidence of the clinical usefulness of this surgery.
