Prospective Study Clinical Trial
Official title:
A Prospective Study of Surgical Treatment Strategies for Goal B Type Basilar Invagination in China
The etiology of Goal B type basilar invagination (BI) is still not clear, and it may be related to platybasia and short slope. There is no unified standard surgical strategy for Goal B type BI, and different surgical strategies have a great influence on the surgical results of patients. The purpose of our prospective study in China is to (1) further clarify the etiology of Goal B type BI, and (2) improve the surgical outcome in these patients.
