Reconsidering the tectorial membrane: A morphological study
Conclusions: The tectorial membrane has a more complex structure than has been described to date in standard anatomical texts. The existence of a layered and banded composition may have implications for understanding its function and for the clinical assessment of this structure.

Factors predicting loss of cervical lordosis following cervical laminoplasty: A critical review
Conclusions: Cervical lordotic alignment is important in maintaining cervical sagittal balance which ultimately is responsible for global spinal sagittal balance and horizontal gaze. Among various radiological parameters, T1 Slope has been reported to be the most important factor affecting cervical alignment following laminoplasty.

Perimedullary arteriovenous fistulas of the craniovertebral junction: A systematic review
Giuseppe Emmanuele Umana, Gianluca Scalia, Bipin Chaurasia, Marco Fricia, Maurizio Passanisi, Francesca Graziano, Giovanni Federico Nicoletti, Salvatore CiceroJournal of Craniovertebral Junction and Spine 2020 11(3):157-162 Perimedullary arteriovenous fistulas (PMAVFs) are uncommon vascular malformations, and they rarely occur at the level of the craniovertebral junction (CVJ). The therapeutic management is challenging and can include observation alone, endovascular occlusion, or surgical exclusion, depending on both patient and malformation characteristics. A systematic literature search was conducted using MEDLINE, Scop...

Lessons learned from surgical management of craniovertebral instability in Morquio syndrome: A series of four unusual cases
We present a series of four cases (mean age 4.3 ± 0.4 years) operated through posterior-only approach (n = 2, C1-lateral mass to C2 pars-interarticularis [Goel's technique]; n = 1 sublaminar wiring followed by C1-lateral mass to C2 pars-interarticularis; and n = 1 suboccipital plate with pars-interarticularis of C2 screw and pedicle of C3 and rod fixation). All patients had acceptable outcome and doing well at the last follow-up (12–96-follow-up). None of our patient needed transoral decompression. Patients with MS frequently manifest with spastic quadrip...

Silent stellate ganglion paraganglioma masquerading as schwannoma: A surgical nightmare
Saswat Kumar Dandpat, Survendra Kumar Rajdeo Rai, Abhidha Shah, Naina Goel, Atul H GoelJournal of Craniovertebral Junction and Spine 2020 11(3):240-242 A 28-year-old normotensive female presented with Horner's syndrome and paresthesia over the left side of the chest. Imaging study showed a large heterogeneous enhancing lesion in short-T1 inversion recovery sequence with flow voids in T2W sequence of magnetic resonance imaging. The lesion was located in the left-sided D1 and D2 regions extending into the neural foramina and apical part of the lung. During surgery, even minimal dissection of the tumor resulted in...

Rotational dislocation C1 & #8211;C2 after otoplasty under local anesthesia
Thiago Dantas Matos, Romulo Pedroza Pinheiro, Herton Rodrigo Tavares Costa, Helton Luiz Aparecido DefinoJournal of Craniovertebral Junction and Spine 2020 11(3):237-239 Non-traumatic rotational atlantoaxial subluxation (NTARS) is rare and mostly reported after infection of the upper respiratory tract and named Grisel's syndrome. NTARS has also been reported after head-and-neck surgery, but it is extremely rare after otoplasty. A case of NTARS after bilateral otoplasty is reported under local anesthesia, a 15-year-old female being presented with painful torticollis. The diagnosis of atlantoaxial rotatory subluxa...

Timing to surgery of Chiari malformation type 1 affects complication types: An analysis of 13,812 patients
This study aims to identify if early operation produces better perioperative outcomes or if there are benefits to delaying CM surgery. Aims and Objective: Assess outcomes for Chiari type I. Methods: The KID database was queried for diagnoses of Chiari Malformation from 2003-2012 by icd9 codes (348.4, 741.0, 742.0, 742.2). Included patients: had complete time to procedure (TTP) data. Patients were stratified into 7 groups by TTP: Same-day as admission (SD), 1-day delay (1D), 2-day delay (2D), 3-day delay (3D), 4-7 days delay (4-7D), 8-14 days delay (8-14D), >14 days delay (>14D). Differences in pre-o...

Epidemiologic trend of mobile spine and sacrum chordoma: A National population-based study
Conclusion: Epidemiology characteristic of chordoma in Iran is similar to other studies; however, the total ASIR was lower and the incidence in sacrum is nearly twice respect to the mobile spine. While men affected by sacral chordoma in relatively older age, the female patients had higher mean age in case of mobile spine involvement. The survival rate of chordoma is significantly lower in comparison with other studies. (Source: Journal of Craniovertebral Junction and Spine)

Biomechanics of the upper cervical spine ligaments in axial rotation and flexion-extension: Considerations into the clinical framework
Conclusion: These outcomes supply relevant biomechanical characteristics of the UCS ligaments in flexion-extension and axial rotation by quantifying length and moment arm magnitude. Moreover, 3D anatomical modeling and motion representation can help in the process of understanding of musculoskeletal behaviors of the craniovertebral junction.
