A weightlifter attempts a deadlift with excessive lumbar rounding. Which failure mode becomes likely when the posterior ligamentous structures are subjected to prolonged tensile stress?

💡 Explanation

Prolonged tensile stress due to excessive lumbar rounding during a deadlift can lead to posterior annulus fibrosus micro-tearing because the ligamentous structures are stretched beyond their physiological limits, therefore the annulus fibrosus undergoes microscopic damage, rather than enhanced remodeling or increased nutrient diffusion which would require compressive loading.
