| Description
| - Reason for performing study: The relationship between mechanical behaviour and microscopic structure of the laminar junction of equine hooves under testing conditions requires elucidation. Objectives: To determine mechanical parameters and 2D length density of profiles of secondary lamellae of the laminar junction in the dermal region and to assess possible correlations. Methods: Specimens (25 samples in total) of the laminar junction were taken from front, quarter and heel parts from 3 equine hooves and exposed to a uniaxial tensile test until rupture to obtain Young's moduli of elasticity, ultimate stress and strain. Neighbouring specimens to those used for the biomechanical experiment were processed histologically to assess the length density of laminar junction basement membrane using stereological grids. Results: The estimated median (interquartile range) length density of the laminar junction basement membrane was 0.024 (0.020-0.027)/mm. Young's modulus of elasticity was 0.15 (0.11-0.35) MPa in the small deformation region, and 7.58 (6.14-8.68) MPa in the linear region was. The ultimate stress was 1.67 (1.41-2.67) MPa, and the ultimate strain was 0.50 (0.38-0.70). The Young's modulus of elasticity in the region of small deformations has a moderate correlation with the length density of the laminar junction basement membrane. Conclusions: As with most soft biological tissues, the laminar junction has a nonlinear mechanical behaviour. Within the range of small deformations, which correspond to physiological loading of the laminar junction, a higher length density of the laminar junction basement membrane is correlated with a higher resistance of the laminar junction against high stresses transmitted from the distal phalanx to the hoof wall.
