Thank you for all your support for the the previous video on this technique. I think, it is the most watched (35K+) C1-C2 surgical technique video on Youtube!
It took me 4 years + to give this video a voice over. Please check out the new version. I have also included the surgical technique of the C1 posterior arch screw in this video (4:31).
This presentation was made at the Advanced Cervical Spine Course conducted by Dr. Sandeep Sonone and Dr. Kshitij Chaudhary for the Bombay Orthopaedic Society.
This course is conducted yearly at the KEM Hospital, Mumbai. For more information visit http://bombayorth.org/academics/instructional-courses/

Excellent surgical video of anterior odontoid screw fixation published by the AAOS
Indications for an anterior odontoid screw fixation are:
1. Acute Type 2 fracture with favorable fracture anatomy
2. Shallow Type 3 fracture with an intact C2 vertebral body
4. Intact Transverse ligament
5. A young patient with good bone stock
The video is by doctors Manuel Valencia, Paulina De La Fuente, Selim Abara, Felipe Novoa, Andreas Leiva, Arturo Olid

This is a talk on vertebral artery injury and how to tackle it if it happens during craniovertebral surgery.
In brief, the vertebral artery can be injured in two locations:
- Extraosseous injury (open space injury): The vertebral artery (VA) is vulnerable to injury above the C1 posterior arch and lateral to the atlantoaxial joints. Sometimes, there is an anomalous course of VA than can get injured. The bleeding tends to be torrential. The quickest way to stop bleeding is by using tamponade for about 20-30 minutes. Endovascular intervention may be required if the bleeding cannot be controlled. Ligation or repair of the VA in this region is technically quite challenging.
- Intraosseous injury (in the screw hole): The VA is vulnerable to injury in the C2 pars especially if it has an anomalous course (high riding VA). The bleeding can be controlled by using bone wax and by inserting the screw. The opposite side has to be abandoned to prevent bilateral VA injury. Postoperative angiography may be needed to assess the damage or to detect ongoing bleeding.
Dr. Robert Bohinski, a neurosurgeon with Mayfield Chiari Center, explains the causes, symptoms, diagnosis and treatment of Chiari malformation type 1. This patient webinar originally aired January 18, 2014.

This is a highly instructive and comprehensive talk, especially for orthopedic spine deformity surgeons, who frequently encounter this pathology in patients with scoliosis.

This is a surgical technique video demonstrating posterior atlantoaxial fusion (C1 lateral mass – C2 pedicle screw fixation) technique as described by Dr. Goel and Dr. Laheri, which was subsequently modified by Dr. Jurgen Harms.
Patient is a 45 year old woman with atlantoaxial instability due to Rheumatoid arthritis. She presented with intractable neck pain without myelopathy. Since the PADI (posterior atlanto-dens interval) was significantly reduced, decision was taken to perform C1-C2 fusion.
