[Tensile strength properties of lower limb nerves in the mature age].
Tensile strength and deformation properties of tibeal and common fibular nerves were analysed in 78 cadavers of both sexes people aged from 21 to 60. It was established that in mature age nerve tensile strength and elasticity increases with low extent of elongation. At the age from 21 to 50 tensile strength and rigidity decrease with significant deformations due to nerve fibre degeneration. After 50 ys tensile strength and rigidity grow higher due to the developing sclerosis of nerve trunks. The nerves studied posses equal tensile strength that decreases synchronously during the period of maturity. Changes of deformation and tensile strength properties of the nerves within the period of maturity is connected with age-related reorganization of their intratruncal structure. Diversities in mechanical properties of different nerves is determined by qualitative and quantitative peculiarities of their morphological structure.
