<strong>Introduction:</strong> The anatomy of atlas vertebra shows extensive variability in form and size, and also undergoes many structural modifications it is located at point close to the vital centres of the medulla oblongata which can get compressed by a dislocation of the atlantoaxial joint or instability of the atlantoaxial joint. Atlas vertebra helps in complex biomechanical movements of the skull along with weight transmission of skull to spine.

<strong>Introduction: </strong>Calcaneum is the longest, strongest and biggest of all the tarsal bones of the proximal row.Anterior and posterior articulations between the calcaneus and talus form a functional unit termed the talocalcaneal or subtalar joint.

The lateral masses of axis have good cancellous bone quality beneath the articular surface of facets that make this area a good site for the insertion of an internal fixation device. Methods. 60 dry axis vertebrae were obtained for anatomic evaluation focused on pedicle, superior and inferior articular facets, and foramen transversarium.

Abstract:

Background: Percutaneous endoscopic lumbar discectomy (PELD) has become an increasingly popular minimally invasive spinal surgery. Due to the technical evolution of PELD, the focus of decompression has shifted from the central nucleus to the subannular-protruded disc herniation, which allows direct neural decompression. Surgical entry into the spinal canal leads to the greater possibility of bony structure obstruction, thus the location and direction of the working channel are crucial.

Abstract:

Background. We devised a new morphological parameter called the superior articular process area (SAPA) to evaluate the connection between lumbar foraminal stenosis (LFS) and the superior articular process. Objective. We hypothesized that the SAPA is an important morphologic parameter in the diagnosis of LFS. Methods. All patients over 60 years of age were included. Data regarding the SAPA were collected from 137 patients with LFS. A total of 167 control subjects underwent lumbar magnetic resonance imaging (MRI) as part of a routine medical examination. We analyzed the cross-sectional area of t

Abstract:

Object. Placement of pedicle screws into S-1 is difficult. In cases in which there is a closed posterior superior iliac spine (PSIS), its medial situation prevents lateral oblique placement of the screw inserter sleeve and directing the screw to the anteromedial aspect of S-1. In the present study, the authors discuss anatomical variations of the PSIS and sacrum, and they describe a safe and effective S-1 screw insertion technique. Methods. The relation of 50 PSISs obtained from 25 dry pelvises (15 male and 10 female cadavers) was examined. The distance from the inferolateral aspect of the S-1

Abstract:

Object. The medial tubercles of the atlas serve as the attachments of the transverse ligament and provide an important anchoring site for which no discussion of their fine anatomy is published in the literature. In this study the authors examine this anatomy along with its osseous relationships. Methods. One hundred dry cadaveric atlantal tubercles were assessed for size and relationship to nearby anatomical osseous structures. In addition, eight cadaveric specimens were evaluated for their anatomy in this area. All specimens exhibited atlantal tubercles for the attachment of the transverse po

Purpose. To correlate treatment results of intra-articular calcaneal fractures with their computed tomographic (CT) classification. Methods. 36 men and 4 women with 48 intra-articular calcaneal fractures (8 bilateral) underwent open reduction and internal fixation with bone grafting via an extensile lateral approach. Based on 2-dimensional CT scans, the fractures were categorised using the Sanders classification. There were 16 type-II, 20 type-III, and 12 type-IV fractures. Radiographs and Maryland foot scores were used for evaluation of the results at a mean of 38 (range, 26–66) months. Resul

Abstract:

✓ A special variant of rotary displacement of the cervical spine with vertical splitting of an inferior articular process by its articulating partner is reviewed. Eighteen patients with unilaterally locked facet joints confirmed by computerized tomography were seen between 1986 and 1991. Five patients presented with vertical split fractures of an inferior articular process by impaction of the superior process of the subjacent vertebra. This specific fracture pattern is not accounted for in current classifications. Four males and one female with a mean age of 31 years (range 16 to 49 years) wer

Background Lumbar facet nerve (medial branch) blocks are often used to diagnose facet joint-mediated pain. The authors recently described a new ultrasound-guided methodology.

The target point was the groove at the cephalad margin of the transverse (or costal) process L1-L5 (medial branch T12-L4) adjacent to the superior articular process.

In addition, 12 cadaver specimens were used to study the posterolateral approach. The bony window was bounded medially by the lateral tubercle of the posterior process of the talus, laterally by the fibular facet, superiorly by the trochlear articular surface, and inferiorly by the posterior calcaneal facet. The average vertical thickness at 2-mm increments was recorded across the talar neck to define the bony mass available for screw insertion. The smallest th

Abstract:

Fixation for atlantoaxial dislocation is a challenging issue, and posterior C1 lateral mass and C2 pars–pedicle screw plate–rod construct is the standard of care for atlantoaxial instability. However, vertebral artery injury remains a potential complication. Recent literature has focused on intraoperative navigation, the O-arm, 3D printing, and recently use of robots for perfecting the trajectory and screw position to avoid disastrous injury to the vertebral artery and enhance the rigidity of fixation. These technological advances increase the costs of the surgery and are available only in sel

BackgroundPain of lumbar facet-joint origin is a common cause of low back pain in adults and may lead to chronic pain and disability, with associated health and socioeconomic implications. The socioeconomic burden includes an inability to return to work resulting in loss of productivity in addition to direct and indirect health-care utilisation costs. Lumbar facet-joints are paired synovial joints between the superior and inferior articular processes of consecutive lumbar vertebrae and between the fifth lumbar vertebra and the sacrum.

AbstractBow Hunter syndrome manifests when the vertebral artery is compressed following head rotation. Symptomatic compression with vertebral artery stenosis due to cervical osteophytes is a rare cause and occurs due to a progressive degenerative process. In most cases, compression originates anteromedially from the uncinate process and is asymptomatic due to the competence of the contralateral vertebral artery. In the described patient, compression presented superomedially due to osteophytes in the superior articular facet of the C5 vertebra, and the contralateral vertebral artery was obstruc
