Methods and materials
- Non-randomized retrospective cross-sectional study.
IRB/MRC approved.
- Inclusion criteria: Patients of both genders (Ages 18-64 years old) who had been investigated by MRI of the whole spine.
- Exclusion criteria: Incomplete MRI studies like unavailable coronal localizer.
- Study included MRI examinations between 1/1/2017-1/3/2018.
- Patients were divided as having a transitional lumbosacral vertebra (LSV) which may be either sacralization and lumbarization,
and a similar number of control group of patients with no transitional vertebra.
- MRI examinations were used for assessment of lumbar spine numbering using the parameters namely:
- Topmost sacral origin level of piriformis muscle.
- Topmost spinal origin level of psoas major muscle.
- Vertebral level corresponding with the superior margin of iliac crest.
- Vertebral attachment level of ilio-lumbar ligament.
- These landmarks were evaluated using the gold-standard enumeration,
which was numbering the vertebrae from C2 downwards in sagittal whole spine MR.
