Aims and objectives
Investigate the reliability of spinal attachments of Piriformis and Psoas major muscles as landmarks for lumbar spine numbering. Assess a clinically well known but radiologically not well investigated parameter for the vertebral enumeration purpose; the iliac crest level. Study the spinal attachment level of Ilio-lumbar ligament. Assess the outcome of combining more than one landmark,
and if this can increase the reliability.
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...
Total number of cases: 60 Cases with transitional LSV (Case group): 30 Cases with Sacralization: 20 Cases with Lumbarization: 10 Cases without transitional LSV (Control group) : 30 Demographics: Gender: 31 males (51.6%) and 29 (48.4%) females.

Piriformis and psoas major muscle topmost attachments,
iliac crest level and ilio-lumbar ligamentattachmenthad significant overlap between normal control and transitional LSV case group,
using the gold standard of enumeration from C2 downwards.
These cannot be used to definitely determine if a transitional LSV existed for sure when only lumbosacral spine imaging is available,
and hence were not proven to be reliable for spine enumeration neither as a single parameter nor in combination....
