Objective: The purpose of this study was to analyze the relationship between fracture pattern and the development of acute radiculopathy after osteoporotic lumbar compression fracture.
Methods: This study included 59 patients who underwent bone cement augmentation for osteoporotic compression fracture below the L2 level, which can lead to radiculopathic radiating pain. The patients were divided into two groups according to the presence of radiculopathy (group A : back pain only; group B : back pain with newly developed radiating pain). We categorized compression fractures into three types by the position of the fracture line. The incidence of newly developed radiculopathy was examined retrospectively for each compression fracture type.
Results: The overall incidence of newly developed leg pain (group B) was 25%, and the frequency increased with descending spinal levels (L2 : 0%, L3 : 22%, L4 : 43%, and L5 : 63%). The back pain-only group (group A) had mostly superior-type fractures. On the other hand, the back pain with radiculopathy group (group B) had mostly inferior-type fractures. Most patients in group B showed significant relief of leg pain as well as back pain after bone cement augmentation.
Conclusion: The incidence of a newly developed, radiating pain after osteoporotic compression fractures increased gradually from the L3 to L5 levels. Most of these fractures were of the inferior type, and the bone cement augmentation procedures seemed to be sufficient for relief of both back and radiating pain.
