Abstract:
Objective —To determine prevalence of a radiographic
caudolateral curvilinear osteophyte (CCO) on the femoral neck in various breeds and age groups of
dogs and to evaluate its contemporaneous relationship with degenerative joint disease (DJD) and distraction
index (DI). Design —Cross-sectional prevalence study. Animals —25,968 dogs, including 3,729 German
Shepherd Dogs, 4,545 Golden Retrievers, 6,277 Labrador Retrievers, and 1,191 Rottweilers. Procedure —Data from the University of
Pennsylvania Hip Improvement Program database were analyzed, including ventrodorsal hip-extended,
compression, and distraction radiographs. The CCO and radiographic signs of DJD were considered independent
events and were interpreted as either present or absent. Statistical methods were used to evaluate
the CCO as a possible risk factor for DJD and assess its association with DI, as measured by use of
distraction radiography. Results —When all breeds were pooled, DJD was
detected in 8.6% of dogs, and the CCO was detected in 21.6% of dogs. Among dogs with a CCO,
25.1% had radiographic evidence of DJD. Among dogs without a CCO, only 4% had DJD. Dogs with a
CCO were 7.9 times as likely to have DJD as were those without a CCO. Additionally, DI, weight, and
age were significant risk factors for the CCO. Conclusion and Clinical Relevance —Results confirm
the contemporaneous association between the CCO and DJD and that passive hip laxity, as measured
by use of the DI, is associated with both the CCO and DJD. ( J Am Vet Med Assoc 2002;220:472–476)
