Three-dimensional biomodel use in the surgical management of basilar invagination with congenital cervical scoliosis; correction by unilateral C1-C2 facet distraction
Luis Eduardo Carelli Texeira da Silva, Diego José Cuéllar, Alderico Girão Campos de Barros, Ahsan Ali KhanJournal of Craniovertebral Junction and Spine 2020 11(4):347-350 Biomodels are produced using three-dimensional printers and their use in complex spine surgeries can be quite helpful, especially when complex anatomy is faced. In this case report, we presented a 14-year-old patient who had rigid congenital cervical scoliosis and basilar invagination and abnormalities on a neurological examination. This patient underwent atlantoaxial facet distraction and C1 C2 fusion while using a biomodel of his cranioc...

Retroclival epidural hematoma: A rare location of epidural hematoma, case report, and review of literature
We report two adults diagnosed with retroclival epidural hematoma. One patient was an 89-year-old male with leukemia and thrombocytopenia who sustained a fall and developed a traumatic retroclival epidural hematoma with brainstem compression; surgery could not be performed due to his clinical condition and he died 5 days later. The other patient was a 78-year-old female with atrial fibrillation who developed a spontaneous retroclival epidural hematoma as a result of warfarin use; she was treated conservatively with anticoagulant reversal and methylprednisolone and was subsequently discharged without neurological deficit.

Navigation-assisted extraforaminal lumbar disc microdiscectomy: Technical note
Conclusion: We described a novel use of 2D/3D imaging system navigation in the microsurgical treatment of ELDH that has not previously reported. This technique is safe and effective and provides more intraoperative details compared to fluoroscopy, which can be crucial for the success of the procedure and to reduce complications and particularly indicated in complex cases with altered anatomy.

Junctional kyphosis and junctional failure after multi-segmental posterior cervicothoracic fusion & #8211; A retrospective analysis of 64 patients
Conclusion: In this cohort of patients with mildly pathologic sagittal balance, JK was a rare event after multi-segmental fusion, observed in only 4% of cases. Neither level of UIV nor LIV had an influence on its occurrence; however, nonunion and pathologic sagittal alignment showed a nonsignificant trend.

Anterior cervical osteophytes causing dysphagia: Choice of the approach and surgical problems
Conclusion: The transoral approach is the best surgical route to resect C1 and C2 ACOs, whereas the endoscopic endonasal approach is not indicated. The anterior transcervical approach is easier to resect osteophytes at C3, as well as those located below C3. A combined transoral and anterior cervical approach may be necessary for multilevel osteophytes. (Source: Journal of Craniovertebral Junction and Spine)

Combined transoral exoscope and OArm-assisted approach for craniovertebral junction surgery: Light and shadows in single-center experience with improving technologies
Conclusions: With EX, the role of surgeon become self-sufficient with a better individual surgical freedom compared to endoscopic surgery and excellent 3D vision and magnification. OArm allows an absolutely reliable intraoperative support for a more effective CVJ decompression. Nevertheless, with OArm-assisted neuronavigation, it can be difficult to navigate C1 lateral masses and C2 isthmi, and to convert 3D into 2D real-time navigation, it can become quite complicate. Finally, the association of EX and OArm appears more time consuming compared to the old fashion one. (Source: Journal of Craniovertebral Junction and Spine)
