What does a loss of lumbar curve predict?

The loss of the lumbar curve, which can also be referred to as a loss of lumbar lordosis, is significant in predicting certain health outcomes, particularly in older adults. This change in the spinal curvature can lead to alterations in posture and biomechanics, often resulting in a reduction of spinal stability and an increase in the risk for vertebral fractures.

As the lumbar curve diminishes, the forces exerted on the vertebrae can change, leading to increased compressive loads that can ultimately weaken the bone structure. This weakening, combined with age-related factors such as decreased bone density and osteoporosis, significantly raises the chance of vertebral fractures occurring, particularly with minimal trauma or stress. Therefore, a loss of lumbar curve is a strong predictor of vertebral fractures.

The other options, such as increased range of motion and improved mobility, are not typically associated with a loss of lumbar curvature. Instead, the loss can actually lead to stiffness and reduced functional capabilities. Additionally, while balance may be impacted by various factors, a loss of the lumbar curve alone does not directly result in better balance and may indeed contribute negatively by affecting overall stability.
