Summary
Occipitocervical fixation offers favorable outcomes for craniocervical junction stabilization, with 77% of patients showing neurological improvement. This surgical technique, despite its challenges, can restore function in non-ambulatory individuals.
Area of Science:
- Neurosurgery
- Orthopedic Surgery
- Spinal Surgery
Background:
- The craniocervical junction is critical for head and neck stability.
- Instability can result from conditions like rheumatoid arthritis and cervical metastasis.
- Surgical stabilization is often necessary to prevent neurological compromise.
Purpose of the Study:
- To evaluate the outcomes of occipitocervical fixation in a consecutive series of patients.
- To assess the safety and efficacy of this procedure for craniocervical junction stabilization.
Main Methods:
- Retrospective review of 14 patients (8 male, 6 female) aged 40-81 years undergoing occipitocervical fixation.
- Minimum 2-year follow-up period.
- Neurological status assessed using the Ranawat grade pre- and post-operatively.
- Intra-operative monitoring of somatosensory evoked potentials.
Main Results:
- Primary indications included rheumatoid arthritis (6 patients) and cervical metastasis (4 patients).
- 77% of patients experienced neurological improvement.
- Four of five non-ambulatory patients (Ranawat grade IIIB) regained ambulation.
- No cases of neurological deterioration, spinal cord injury, or vertebral artery injury.
- Complications included one superficial wound infection and two instances of implant breakage.
Conclusions:
- Occipitocervical fixation is a technically demanding procedure with potential risks.
- Favorable results and neurological improvement are achievable.
- It remains a viable surgical option for stabilizing the craniocervical junction.

01:25Secondary Spinal Cord Injury llI: Pathophysiology
Early Ischemia and Ionic ImbalanceWithin minutes of spinal cord injury, a secondary cascade begins, progressing over hours to weeks. Vascular damage reduces blood flow, causing ischemia and mitochondrial dysfunction. ATP depletion leads to ion pump failure, membrane depolarization, sodium influx, potassium efflux, and water accumulation, resulting in cellular swelling. Increased intracellular calcium further disrupts mitochondria and accelerates cellular injury.Excitotoxicity and Neuronal...
01:14Spinal Cord Injury ll: Pathophysiology
Spinal cord injury progresses through two interconnected phases: primary injury and secondary injury.Primary InjuryPrimary injury happens at the moment of trauma and involves immediate mechanical damage to the spinal cord.Compression happens when broken vertebrae, herniated discs, or accumulating blood (such as a hematoma) press directly against the spinal cord, distorting its normal shape and function. In cases of contusion, the cord is bruised by a blunt force (like penetrating injuries or...
