Pelvic morphology influences spinal loading and may predispose individuals to specific types of lumbar spinal degeneration. Anatomic pelvic parameters were found to be specific for distinct degenerative conditions, suggesting a role in disease development.
Area of Science:
- Spine surgery
- Orthopedics
- Radiology
Background:
- Pelvic morphology influences spinal shape, load, and function.
- Specific spinopelvic sagittal profiles may predispose individuals to distinct degenerative lumbar spine pathologies.
Purpose of the Study:
- To investigate the association between specific anatomic pelvic parameters and different types of lumbar spinal degeneration.
- To determine if pelvic morphology is a predisposing factor for conditions like lumbar disc herniation, degenerative disc disease, lumbar spinal stenosis, and degenerative spondylolisthesis.
Main Methods:
- Retrospective cohort study including 249 surgically treated patients with symptomatic lumbar spinal degeneration.
- Classification of pathologies into lumbar disc herniation (LDH), degenerative disc disease (DDD), lumbar spinal stenosis (LSS), and degenerative spondylolisthesis (DSPL).
- Assessment of pelvic incidence (PI), pelvic radius (PR), and sacral table angle (STA) from lateral lumbar spine radiographs.
Main Results:
- Significant differences were observed in PR, PI, and STA among the different degeneration groups.
- Lumbar spinal stenosis (LSS) showed distinct PR compared to other groups.
- Pelvic incidence (PI) differed significantly between degenerative disc disease (DDD) and degenerative spondylolisthesis (DSPL). Sacral table angle (STA) varied between lumbar disc herniation/degenerative spondylolisthesis and lumbar spinal stenosis/degenerative disc disease groups.
Conclusions:
- Anatomic pelvic parameters are specific to distinct types of lumbar spinal degeneration.
- Pelvic shape appears to be a predisposing factor in the development of these spinal conditions.
