CT assessment of the influence of dynamic loading on physiological incongruency of the canine elbow

Objectives To present a novel technique for loading of the canine elbow joint and to quantify changes in congruency with increasing load using computed tomography. Materials and Methods Five pairs of thoracic limbs were mounted at a mid stance angle in a custom made jig. Elbow joints were loaded to 0, 33, 66 and 100% of total individual cadaver bodyweight. At each load computed tomography of the elbow was performed. Joint space measurement was performed on sagittal plane central, lateral and medial compartment images at humero‐radial (R1, R2, R3), humero‐ulnar (U1, U2) and radio‐ulnar loci. The effect of loading on joint spaces was assessed (P
