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.

Complication rates following Chiari malformation surgical management for Arnold & #8211;Chiari type I based on surgical variables: A national perspective
Conclusions: Chiari patients undergoing craniectomies as well as instrumented fusions are at a higher risk of postoperative complications especially when the instrumented fusions were performed on >4 levels. (Source: Journal of Craniovertebral Junction and Spine)

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...

Central atlantoaxial instability as a cause of syringomyelia mimic intramedullary lipoma
Atul Goel, Abhinandan Patil, Abhidha Shah, Survendra Rai, Ravikiran Vutha, Shashi RanjanJournal of Craniovertebral Junction and Spine 2020 11(2):152-154 A case of a 32-year-old male patient is reported. He was admitted with complaints of burning dysesthesias over his right upper limb and chest and spasticity in the legs. Investigations revealed a long segment intramedullary tumor, image intensity of which matched lipoma. Imaging of craniovertebral junction suggested atlantoaxial “facetal” instability. Atlantoaxial fixation was done, and the intramedullary lipoma was not physically handled or mani...

Occipital condyle syndrome in a case of rotatory atlantoaxial subluxation (type II) with craniovertebral junction tuberculosis: Should we operate on & #8220;active tuberculosis ? & #8221;
We present a unique amalgamation of three rare entities: craniovertebral tuberculosis, occipital condyle syndrome, and nontraumatic type II rotatory atlantoaxial dislocation in one patient. We reviewed the limited literature available and the underlying pathophysiology to highlight the pattern of the disease presentation, progression, and response to management options. A 13-year-old girl presented with neck pain, torticollis, and right hypoglossal weakness following a fall from stairs 10 months back. Radiological investigation suggested right occipital condylar destruction with right-sided neck tilt and rotatory atlantoax...

Early percutaneous treatment of an aggressive vertebral hemangioma: A case report with a 5-year follow-up
Pietro Giorgi, Domenico Compagnone, Enrico Gallazzi, Giuseppe Rosario SchiròJournal of Craniovertebral Junction and Spine 2020 11(2):139-142 Vertebral hemangiomas (VHs) are very common radiological findings, and the majority of them are completely asymptomatic and harmless. However, although rarely, they can present as locally aggressive, symptomatic lesions, and requiring surgery. In these cases, early diagnosis and treatment are mandatory to avoid serious complications and invasive surgery; however, there is no consensus about the best therapeutic option. Minimally-invasive percutaneous techniques have re...

Revisiting the surgical corridors for cervical Type IIb-c dumbbell neurofibroma: A series of two unconventional approaches and review of literature
Conclusion: Posterolateral approach for cervical dumbbell giant NFs is safe, effective, and promises maximum safe excision. The major blood vessels including carotid artery or jugular veins in neck and vertebral artery at foraminal portion are directly under vision and control of surgeon. Despite near-total excision, wherein small part of adhered capsule is left, recurrence rate is low. (Source: Journal of Craniovertebral Junction and Spine)
