The most common type of congenital C1-2 dislocation is a combined type in which atlanto-axial dislocation (AAD) and basilar invagination (BI) are often associated with a rotational dislocation and coronal tilt. An optimal surgical treatment involves reduction of AAD and BI with simultaneous correction of the rotation and coronal tilt to achieve an optimal cervical canal decompression, sagittal and coronal realignment and bony fusion. The most acceptable technique to facilitate this correction is the C1-C2 distraction technique, which is accomplished by the manual joint manipulation...

Chiari malformation type I (CM-I) is typically treated with foramen magnum decompression. However, a recent study proposed a new technique for patients with CM-I, wherein only short atlantoaxial joint fusion and distraction is applied. Posterior fusion with or without atlantoaxial distraction is a potential option for patients with CM-I associated with basilar invagination or complex anomalous bony craniovertebral junction pathology, since this procedure allows clinicians to avoid using the technically demanding transoral approach in which some or all of the odontoid tip is invisible...

OBJECTIVES: Manifestation of congenital anomalies of cranio-vertebral junction (CVJ) in the later half of life is unusual and intriguing. Coexisting cervical spondylotic changes with multilevel compression, poorer bone quality as well as less smooth post-surgical recuperation make management of elderly Congenital Atlantoaxial Dislocation/ Basilar Invagination (CAAD/BI) challenging. The clinico-radiological presentation, pathogenesis and outcome are analysed here. PATIENTS AND METHODS: Clinico-radiological data of 20 patients of CAAD/BI (with markers of congenital anomalies) presenting after 50 years of age, the challenges faced and outcomes after C1-C2 fusion have been analysed...

Chiari malformation type I (CM-I) is a common hindbrain disorder that is associated with deformity and elongation of the cerebellar tonsils. Although CM-I occurs in both pediatric and adult patients, its prevalence, clinical features and management in the pediatric population are not well defined. The current study evaluated a consecutive case series of 92 children (38 females and 54 males) who were diagnosed with congenital CM-I. All patients underwent small-bone-window posterior fossa decompression with autologous-fascia duraplasty...

An upward displacement of the odontoid process into the foramen magnum was observed in the skeletal remains of a young male unearthed from a 14th-17th century cemetery in the north-eastern Italy. Examination of skull bone vestiges and CT-SCAN analysis of the axis exhibited a clear-cut contact zone between the odontoid process and the anterior border of the foramen magnum. In addition, the odontoid process appeared backward deviated. Findings suggest a possible diagnosis of basilar impression/invagination. This anomalous contact may cause compression of neural and vascular structures with a multifaceted series of clinical symptoms...

Introduction: The deformed joints seen in congenital atlantoaxial dislocation (CAAD) are often associated with vascular anomalies. It is important to identify these vascular anomalies and address them appropriately without compromising the manipulation and fusion of C1-C2 joints. The small bones in pediatric age group pose an additional challenge. Materials and Methods: Data of fifty-six children with CAAD operated in the last 4 years was analyzed. A computed tomography angiogram was obtained preoperatively to assess for the course of the third segment of vertebral artery (VA)...

BACKGROUND AND IMPORTANCE: The lateral suboccipital approach for microvascular decompression (MVD) of the trigeminal nerve has become a standard-of-care over the past several decades. Syndromic cranial base settling, a rare but known cause for trigeminal neuralgia (TN), poses significant dilemmas in clinical management. In such cases, distorted anatomy may render surgery via the suboccipital approach difficult or even impossible. CLINICAL PRESENTATION: A 34-yr-old male with osteogenesis imperfecta and severe basilar invagination suffered from TN that was refractory to medication and stereotactic radiosurgery...

Surgery for the Cranio-vertebral (CV) junction anomalies using top loading subocciput (C0)/C1-C2 screws is difficult and requires high level of skill and expertise. This is because of complex abnormal anatomy in that region and other issues including the instrumentation. Thorough knowledge of the 3D anatomy of the Craniovertebral junction of the patient is essential for favourable outcome. The customised 3D printed model of CV junction region of the patient can be used for studying the anatomy and relationship of vertebral artery to the C1-C2 joint before the actual surgery...

A simultaneous odontoid decompression and bilateral posterior atlanto-axial facetal distraction, C1-2 joint spacer/bone graft placement and stabilization may be performed utilizing the 'posterior-only' approach. This procedure may be performed utilizing a single posterior midline incision, a bilateral posterior approach to the C1-2 facet joints and a bilateral posterolateral approach to the odontoid process and C2 body. It may be carried out in situations where a C1-2 non-reduction/partial reduction using a 'posterior alone' procedure is anticipated due to the complex bony/soft tissue configuration anterior at the thecal sac existing at the cervicomedullary junction...
