“…A related study (20) demonstrated that the clearance of the L 3–5 bilateral articular processes of an adult are on average 33.5, 40.1 and 47.4 mm, respectively. With the addition of a conventional resection of 1/3-1/2 inside the small joint for intra-operative decompression, the diameter of the general bone window is 14–18 mm and the area is 2.4–3.0 mm 2 .…”

The aim of this study was to observe the clinical effects of bilateral decompression via vertebral lamina fenestration for lumbar interbody fusion in the treatment of lower lumbar instability. The 48 patients comprised 27 males and 21 females, aged 47–72 years. Three cases had first and second degree lumbar spondylolisthesis and all received bilateral vertebral lamina fenestration for posterior lumbar interbody fusion (PLIF) using a threaded fusion cage (TFC), which maintains the three-column spinal stability. Attention was given to ensure the correct pre-operative fenestration, complete decompression and the prevention of adhesions. After an average follow-up of 26.4 months, the one year post-operative X-ray radiographs suggested that the successful fusion rate was 88.1%, and this was 100% in the two-year post-operative radiographs. Moreover, the functional recovery rate was 97.9%. Bilateral vertebral lamina fenestration for lumbar interbody fusion is an ideal surgical method for the treatment of lower lumbar instability. The surgical method retains the spinal posterior column and middle column and results in full decompression and reliable fusion by a limited yet effective surgical approach.

“…Several studies have proven the accuracy of MRI that has recently become a popular imaging modality, in vertebral measurements, identifying the details of its anatomy [12, 36]. Given its high resolution, it has largely replaced the computed tomography (CT) in the differentiation of the several adjacent structures comprising the spine [36]. We utilized MRI for this study rather than CT scans, because it is more reliable in detecting soft tissue degeneration and hence choosing the cases for study [30].…”

Despite the increasing recognition of the functional and clinical importance of lumbar lordosis, little is known about its description, particularly in Egypt. At the same time, magnetic resonance imaging (MRI) has been introduced as a noninvasive diagnostic technique. The aim of this study was to investigate the anatomy of the lumbar lordosis using midsagittal MRIs. Normal lumbar spine MRIs obtained from 93 individuals (46 males, 47 females; 25–57 years old) were evaluated retrospectively. The lumbar spine curvature and its segments “vertebrae and discs” were described and measured. The lumbar lordosis angle (LLA) was larger in females than in males. Its mean values increased by age. The lumbar height (LH) was longer in males than in females. At the same time, the lumbar breadth (LB) was higher in females than in males. Lumbar index (LI = LB/LH × 100) showed significant gender differences (P < 0.0001). Lordosis was formed by wedging of intervertebral discs and bodies of lower lumbar vertebrae. In conclusion, MRI might clearly reveal the anatomy of the lumbar lordosis. Use of LI in association with LLA could be useful in evaluation of lumbar lordosis.

“…In other words, the intervertebral foramen is located anteriorly to the vertebral canal at an angle of 45 o relative to the coronal plane [19]. Therefore, the oblique or axial views have greater confidence rates than the sagittal views, in order to evaluate the presence of foraminal stenosis or of a disc herniation [17,25,36,37,44]. CT -computed tomography; MRI -magnetic resonance imaging…”

“…Many studies have evaluated the vertebral body, spinal canal, and spinal cord [15,26,35]. However, an extremely limited number of studies have reviewed the complete anatomy of the cervical intervertebral foramen (Table 1) [8,10,25,38,40,48]. In fact, there is only one review article describing the anatomy of cervical intervertebral foramen as a whole, which focused on vascularisation.…”
