Summary
This study demonstrates successful surgical treatment of atlantoaxial dislocation with vertebral artery injury using interlaminar screws. Preoperative imaging and surgical skill are key for positive outcomes in complex cervical spine cases.
Area of Science:
- Neurosurgery
- Orthopedic Surgery
- Spinal Surgery
Background:
- Atlantoaxial dislocation requires surgical intervention.
- Vertebral artery injury is a significant risk during this surgery.
- Interlaminar screw technology offers a potential solution.
Observation:
- A 69-year-old female presented with symptomatic atlantoaxial dislocation and developmental vertebral artery anomalies.
- She underwent posterior cervical surgery with interlaminar screw placement.
- Intraoperative vertebral artery injury occurred but was successfully managed.
Findings:
- Postoperative follow-up showed improved clinical symptoms and functional scores.
- Postoperative CT angiography confirmed no vascular complications.
- The patient's condition improved significantly after the procedure.
Implications:
- Thorough preoperative evaluation, including CT angiography, is vital.
- Surgeon expertise in diverse spinal screw techniques enhances surgical success.
- This case highlights the efficacy of interlaminar screws in managing complex atlantoaxial dislocation with vascular injury.

01:28Articulations of the Vertebral Column
1.8K
In addition to being held together by the intervertebral discs, adjacent vertebrae also articulate with each other at synovial joints formed between the superior and inferior articular processes called zygapophysial joints (facet joints). These are plane joints that provide for only limited motions between the vertebrae. The orientation of the articular processes at these joints varies in different regions of the vertebral column and serves to determine the types of motions available in each...

The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.

The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...
