What is a common cause for back injury even when the back is straight?

Lifting and moving objects, even with a straight back, can still lead to back injuries if proper technique is not maintained. Bending forward at the hips while lifting creates a mechanical disadvantage and places excessive strain on the lower back. When the hips are bent, the lumbar spine is subjected to increased stress, particularly when the load is heavy or poorly balanced. This motion can compress the vertebrae and strain the supporting muscles, even if the upper body appears straight.

Maintaining a straight back while bending forward can create an illusion of safety, but fails to account for the fact that the hips are a crucial pivot point for proper lifting technique. Keeping the hips in line and bending at the knees is essential for effective lifting mechanics, which minimizes the risk of injury by allowing the legs to bear the weight instead of the back.
