“…[4][5][6] Successful long-term treatment of HD with DPO has been demonstrated 12 ; however, poor candidate selection may lead to treatment failure with progression of hip arthritis and degenerative joint disease in treated dogs. 8 Despite the utility of the DI for predicting future development of coxofemoral joint disease, it is not clear that the magnitude of the DI would be an accurate predictor of the current level of degenerative changes in any individual hip joint. Arthroscopy is considered the gold standard for assessing articular cartilage, synovium, and intra-articular ligaments in many joints in the dog and in other species 8,10,13 but is not routinely used to assess the coxofemoral joint in dogs prior to DPO surgery.…”

The study reported here provides evidence that the results of arthroscopic assessment of coxofemoral joint cartilage and support structure (DAR, ligament of insertion of the femoral head, and labrum) wear do not correlate with the degree of coxofemoral joint laxity as measured by the DI.…”

“…Arthroscopic evaluation of the hip joint has been reported to be a more accurate method than traditional radiography for identifying pathologic lesions in young dogs with HD. 8 Evaluation of standard pelvic radiographs followed by hip arthroscopy has been reported as a means of selecting candidates for triple pelvic osteotomy. 8 The authors routinely measure DI and perform hip arthroscopy as part of the selection process for dogs being considered for DPO surgery and are unaware of any studies that have compared the magnitude of DI measurement with arthroscopically diagnosed joint pathology.…”

Objective: To compare distraction index (DI) with hip arthroscopy findings in juvenile dogs with hip dysplasia undergoing unilateral or bilateral double pelvic osteotomy (DPO). Study design: Retrospective case series. Animals: Twenty dogs (36 hip joints). Methods: Medical records from dogs undergoing unilateral or bilateral DPO (2011)(2012)(2013)(2014)(2015)(2016) were reviewed. Distraction index was measured by using distraction view radiographs. Arthroscopic images were analyzed. Cartilage was graded by using the modified Outerbridge scale (0 = arthroscopically normal, 1 = chondromalacia, 2 = surface fibrillation, 3 = deep fissuring, 4 = full-thickness cartilage loss, and 5 = eburnation of exposed subchondral bone). Dorsal acetabular rim, acetabular labrum, the ligament of head of the femur, and synovitis were graded by using a four-point scale (normal, mild, moderate, severe). Spearman and Pearson correlations were used to compare DI between grade groups and age. Results: Distraction index ranged from 0.4 to 1.0 (mean 0.69 ± 0.16). Most of the hips had an arthroscopically normal femoral head and acetabulum in most regions, except for the region at the insertion of the ligament of the head of the femur. There was a low positive correlation between synovitis and DI (Spearman ρ = 0.35, P = .0346). No other differences in DI were identified between grade or age groups. Conclusion: There was a low positive correlation between synovitis and DI. No other differences in DI were identified. Clinical significance: Arthroscopic evaluation of the coxofemoral joint prior to DPO can allow detection of joint pathology that might not be appreciated by using traditional radiographic screening criteria.

OBJECTIVE To evaluate the technical feasibility and efficacy of a hip joint distraction technique, any potential ligamentous damage linked to the procedure, and the effect of joint venting on the maximum distraction achieved. METHODS Twenty hip joints from 11 canine cadavers were evaluated radiographically by standard and stressed projections. Joint distraction was applied with loads from 40 up to 200 N, in 40 N increments, and fluoroscopic images were obtained at each load. At 200 N, a needle was inserted into the joint to achieve a venting effect, and the space was measured again. Standard and stressed radiographs were performed to evaluate potential laxity changes. RESULTS Distraction caused a significant increase in joint space at each load of distraction, although there were some variations. Joint venting produced a significant increase in joint space. A statistically significant difference in joint laxity evaluated radiographically before and after the procedure was recorded. CLINICAL SIGNIFICANCE Use of the distraction apparatus resulted in an increase in joint space. This could be useful for clinical situations where a larger joint space is required such as for arthroscopic procedures. However, loads in excess of 200 N may induce significant increases in joint laxity.
