“…Previous studies have demonstrated positive correlation between some of these variables. One such study using digital caliper measurement of PD in cadavers showed that taller and heavier subjects had statistically significant larger PD [10]. A similar CT based study on a Turkish population demonstrated that transverse PD values are directly proportional to subject height [11].…”

Background Safely performing instrumented spinal fusion requires an intimate knowledge of anatomy and variations. Pedicle screw position and size have implications on intraoperative and post-operative complications. While pre-operative planning with Computed Tomography (CT) scan measurements may be the safest way to judge trajectory and maximal screw size, it is not standard practice for many spine surgeons. We investigated how height and weight correlated with PD. We hypothesized that these routinely obtained, non-invasive measurements would provide an easily referenced data point to aid in perioperative estimation of maximum safe pedicle screw diameter (MSPSD).Methods Coronal cuts of the lumbar spine were assessed to obtain transverse outer cortical PD as measured through the isthmus at lumbar vertebrae one through five. We assessed whether height, weight, and BMI significantly correlated with PD in our diverse population. ResultsHeight and weight were found to significantly correlate with PD. Height explained roughly 10% of the variance in PD, weight explained only 3-4%, and BMI nearly 0%. There were significant differences in this theoretical safety profiles between the "Taller Height" and "Shorter Height" groups for the majority of pedicle screw sizes at L1 through L3. Significant differences between the populations at L4 and L5 were only seen for 8.0 mm screws at the L4 level. At L5, 100% of the "Taller Height" and "Shorter Height" subjects' pedicles could safely accommodate pedicle screws up to 8.0

“…While focusing on the reasons of the narrow spinal canal, few studies has been conducted on LP so mean lateral elements of the vertebra. (5)(6)(7)(8)(9)(10)(11). They demonstrated that significant differences value of LP between variability including ethnicity, age, gender, height and weight and vertebral levels.…”

“…But degenerative changes in vertebral bone elements such as lumbar pedicle (LP) have not been so investigated in LSCS yet. However for effective and healthy lumbar stabilization LP morphology has been investigated in many studies and it has been proved that LP mostly shows anatomic variabilities (5)(6)(7)(8)(9)(10)(11). Base on these datas, we aimed to investigate the relationship of LP thickness (LPT) with LSCS using MRI.…”

Background: Lumbar spinal canal stenosis (LSCS) is an important cause of morbidity in the elderly population. Many morphological abnormalities such as facet joint hypertrophy, ligamentum flavum hypertrophy, disc herniation combined with osteophytes associated with LSCS were investigated. Degenerative changes in all the elements of the vertebral bone such as lumbar pedicle thickness (LPT) has not evaluated clearly. The aim of this study to investigate whether LPT can be a morphological parameter to predict LSCS using magnetic resonance imaging (MRI). Materials and Methods: 150 patients diagnosed clinical LSCS and 150 control subjects who did not have LCSC-related symptoms referred to radiology unit to undergo lomber MRI enrolled the study. LPT was measured at the most stenotic level of the L5 vertebra using axial T2-weighted images. Results: The mean LPT value was 14.70±1.94 mm in the LSCS group and 14.23±2.00 mm in the control group and was higher in patient group than the controls but did not reach statistical significance (p=0.082). Conclusion: LPT cannot be an effective factor to predict patients with LSCS.

“…Yu, et al [8], have shown significant correlation between lumbar pedicle morphometry, gender, height and weight utilizing digital calipers on a population of American human cadavers. Gulec, et al [9], have utilized three-dimensional CT to compare gender, age and height with pedicle morphometry in a Turkish only population. Another study utilized electronic calipers to compare the pedicles in a small (12 specimen) Greek only cadaveric study [10].…”

BackgroundSpinal surgery requires an intimate understanding of pedicle morphology to provide safe and effective outcomes. Although current research has attempted to identify morphological vertebral pedicle trends, no study has utilized computed tomography (CT) scans to compare the lumbar transverse pedicle angle (TPA) with patient demographics factors in a diverse population throughout multiple hospital centers.MethodsAnalysis of randomly selected CT scans from L1-L5 of 97 individuals who underwent imaging over a two-week period for non-back pain related complaints was conducted. Measuring 970 TPAs in total allowed for comparison of each patients’ pedicle angle with important patient specific demographics including ethnicity, age, gender, height and weight. Statistical analysis utilized multiple comparisons of demographics at each level with post-hoc Bonferroni correction analysis to compare demographics at each level.ResultsWith relation to gender, age, height or weight, no statistically significant differences were identified for TPAs at any vertebral level. However, when stratified by ethnicity, the differences in transverse pedicle angles averages (TPA –Avg) at L2 and L3 were found to be statistically significant (p < 0.05).ConclusionWe have identified a previously unknown and significant relationship between ethnicity and TPA at lumbar vertebral levels. These findings provide critical information that may be added to the operating surgeons’ knowledge of pedicle morphology. We hope this novel information can assist in preoperative planning of pedicle screw placement and potentially help improve surgical outcomes.
