AB Torsional loading of the growth plate occurs in daily activities and sports and is associated with growth platefractures. This study aimed to investigate the microstructural and mechanical properties of growth plate tissueunder torsional loading, focusing on variations across individuals, growth plate types, and anatomical locations.A total of 140 samples from three distinct growth plates in five porcine subjects were subjected to cyclictorsion tests followed by ultimate failure testing. Additionally, histological analyses were performed usingMovat’s pentachrome staining to assess tissue structure.Mechanical testing revealed significant differences in shear moduli across growth plate types; notably, theproximal femur exhibited a higher primary shear modulus compared to both the distal femur and proximal tibia.Correlation analyses showed a negative relationship between hypertrophic zone thickness and primary shearmodulus (ρ = − 0.47 at 0.5◦/s, p < 0.001), as well as between cell column angle and secondary shear modulus(ρ = − 0.43 at 0.5◦/s, p = 0.015).This study provides essential insights into the mechanical behavior of growth plates and how structuralvariations influence their response to loading, aiding in the development of more accurate computationalmodels.
