The first reason is aging of the human body. As the body ages, the lumbar spine inevitably exhibits degenerative changes due to wear and tear from movement, and the majority of people over 60 show the formation of bone spurs in X-ray images. The second reason is injury caused by overexertion. Overexertion, due to excessive workload and excessive activity, aggravates the degeneration of the lumbar spine, leading to the formation of bone spurs. The third reason is a history of trauma. Trauma to the lumbar area during one's youth can lead to bone proliferation in the lumbar spine in middle and old age. The fourth reason is improper posture. Bone proliferation in the lumbar spine in young patients is mainly due to maintaining the same posture for long periods, improper posture, and sleeping on soft beds, all of which can lead to bone proliferation over time. These are the main reasons for bone proliferation in the lumbar spine currently observed in clinical settings.
