The occipitocervical junction with its complex anatomy and biomechanics represents unique anatomical structure difficult for operative treatment. Biomechanics forces in this region need to be resisted with rigid metallic construction to facilitate bone fusion. Surgeon must be careful about close relations of the bone, vascular and neurologic structures and must have good skills and knowledge to avoid serious complications during operations. Before 2004 for instability treatment in this region of spine wires and pin construction for fixation of bone grafts were used. In our Institute rod constructions with screws have been used to get more rigid construction since 2004. In this paper we will present our early results in occipitocervical instability treatment by SUMMIT instrumentation.

Case: A 47-year-old man presented with neck pain, restricted neck movements, along with involvement of facial and hypoglossal nerve. On the basis of clinico-radiological correlation, the patient was diagnosed with craniovertebral junction tuberculosis and was started on antitubercular therapy (ATT). Failing the conservative trial, the patient was operated and occipitocervical fusion was done with bone grafting.

Article Synopsis
- Study aims to find the best way to secure clival screws for treating occipitocervical instability due to the complex shape of the clivus.
- Seven finite element models were created to analyze the biomechanics of different screw configurations, applying rotational forces to test stability.
- Results showed that using three clival screws in a triangular arrangement provided optimal support and lower stress on the devices, indicating it is the best fixation method for this area.

Article Synopsis
- * A comprehensive literature search identified 106 studies involving 2086 pediatric patients, with the majority of cases stemming from atlantoaxial instability and often utilizing iliac crest or rib autografts for surgery.
- * The review reports a high overall fusion rate of 95.8% for these pediatric procedures, with similar success rates observed for cases involving the occipitocervical junction compared to those without such involvement.

The occipitocervical junction (OCJ) is a complex anatomical region crucial for protecting the lower brain stem, upper spinal cord, and lower cranial nerves. Instability in this area can lead to severe outcomes such as chronic pain, neurological deficits, or death. Various surgical techniques have been developed for OCJ stabilization, particularly using occipital condyle screws, which have shown promise in providing stability and preserving neck rotation.

Article Synopsis
- Os odontoideum is a rare anomaly in the cervical spine that can lead to instability at the atlantoaxial joint.
- Depending on its type, this instability can cause anterior subluxation (common) or posterior subluxation (very rare).
- Posterior subluxation is especially dangerous as it can result in myelopathy and potentially lead to serious outcomes like quadriplegia or death.
