PurposeLumbar spinal stenosis syndrome (LSSS) is induced by factors such as ligamentum flavum hypertrophy, facet joint hypertrophy and disc degeneration. However, the role of lumbar pedicle (LP) in LSSS has yet to be evaluated. We devised a new morphological parameter called the lumbar pedicle thickness (LPT) to evaluate the connection between LSSS and the LP. We hypothesized that the LPT is a major morphological parameter in the diagnosis of LSSS.Patients and methodsThe LPT data were collected from 136 patients diagnosed with LSSS. A total of 99 control subjects underwent lumbar spine magnetic resonance imaging (MRI) as part of a detailed medical assessment. Axial T2-weighted magnetic resonance (MR) images were acquired from all the participants. Using our picture archiving and communication system, we analyzed the thickness of the LP at the level of L5 vertebra on MRI.ResultsThe average LPT was 9.46±1.81 mm in the control group and 13.26±1.98 mm in the LSSS group. LSSS patients showed a significantly greater LPT (P<0.001) than the control group. The receiver operating characteristic (ROC) curve analysis showed an optimal cutoff point of 11.33 mm for the LPT, with 83.8% sensitivity, 83.8% specificity and area under the curve of 0.92 (95% confidence interval [CI], 0.89–0.96).ConclusionA higher LPT was associated with a higher possibility of LSSS, suggesting its importance in the evaluation of patients with LSSS.

“…Studies of agerelated variations of the vertebral elements have largely been limited to the vertebral body and intervertebral discs (Allbrook, 1956;Ericksen, 1976Ericksen, , 1978aOda et al, 1988;Amonoo-Kuofi, 1991;Gocmen-Mas et al, 2010); in those studies, the vertebral elements were analyzed from an anthropological perspective rather than focusing on clinical or surgical applications. The literature contains very few reports about the vertebral pedicle, and those are limited to the lumbar region (Amonoo-Kuofi, 1995;Mughir et al, 2010).…”

“…The variations in the vertebral pedicle with respect to age have been studied by Amonoo-Kuofi (1995) and Mughir (2010). Their studies were limited to the lumbar region, where they found significant age-related variations in the horizontal and vertical diameters in the study groups (Amonoo-Kuofi, 1995;Mughir et al, 2010).…”

“…The general morphometric characteristics of the thoracic spine pedicle have been widely studied (Zindrick et al, 1987;Islam et al, 1994;McCormack et al, 1995), and some authors have considered the differences between genders (Amonoo- Kuofi, 1995;Mughir et al, 2010). However, to date, no thoracic spine studies have examined variations in pedicle dimensions with respect to age and gender for any population.…”

Transpedicular spinal fusion is the most commonly used fixation technique for the surgical treatment of vertebral disorders. However, the instrumentation of the thoracic spine using this technique continues to be controversial. The objective of the present study was to determine the morphometric characteristics of the thoracic pedicle and to establish how these characteristics vary with gender and age. Two hundred thoracic spines (4800 thoracic pedicles) from individuals of known gender and age were analyzed (in accordance with the order of vertebrae). The spines were divided into six groups according to age and gender. The horizontal and vertical diameters of the thoracic pedicle were determined for each piece. The mean and standard deviation of each variable were determined, and differences between age groups for each gender were evaluated using parametric correlation tests. The pedicle diameters of men and women differed significantly for most groups (P < 0.05). The horizontal diameters decreased from T1 to T5 and increased up to T12. The vertical diameter followed a cephalocaudal pattern of development from T1-T12. The pedicle diameters decreased with increasing age in women, while the opposite trend was observed in men. In men, the dimensions of the thoracic spine pedicle increase with increasing age; in women, they decrease. These differences should be taken into account when selecting the appropriate pedicle screw.

Morphological comparison between adolescent and adult lumbar pedicles using computerised tomography scanning

Abstract: Pedicle morphology in adolescent and adult population is different in all parameters, especially in males. Understanding of specific pedicle morphology for each group is imperative for safety in spinal procedures using pedicle route.
