椎間盤 DISK (INTERVERTEBRAL)

椎間盤是一種異質(zhì)性的軟骨結(jié)構(gòu)，有助于脊柱的柔韌性和負(fù)荷支持。在生物力學(xué)上，椎間盤承受不同類型的載荷和應(yīng)力，如靜態(tài)、動態(tài)和扭轉(zhuǎn)載荷，以及拉伸、壓縮和剪切應(yīng)力。椎間盤退變是下腰痛的一個重要問題。椎間盤的力學(xué)性質(zhì)對于理解椎間盤疼痛的模式和機制特別有意義。

The intervertebral disc is a heterogeneous, cartilaginous structure that contributes to flexibility and load support in the spine. Biomechanically, the disc is subjected to different types of load and stresses such as static, dynamic and torsional loads, as well as tensile, compressive and shear stresses. Intervertebral disc degeneration is an important problem concerning lower back pain. Mechanical properties of intervertebral discs is of particular interest in understanding the patterns and mechanics of disc pain.
