Thoracic Limb Angular Deformity in Chondrodystrophic Dogs: Repeatability of Goniometric Measurement of External Rotation and Carpal Valgus

Abstract Objective We aimed to provide repeatable methods for quantifying antebrachial valgus and rotation in dogs with without complex angular deformities. Thus, we investigated the repeatability of two measure carpal one method external thoracic limb a standing position. Study Design This was prospective observer agreement study sample 18 non-chondrodystrophic as baseline 43 chondrodystrophic dogs. The measurements (ROT), modified (VALG-M), established (VALG) were done independently by investigators. Repeatability assessed intraclass correlation coefficient (ICC). Results measured mean (± standard deviation) angles ROT, VALG-M, VALG 14 degrees 5 degrees), 9 4 3 degrees) 30 13 23 11 ROT VALG-M respectively. In dogs, ICC low errors 1 6 degrees, whereas intra- intertester high 8 degrees.
