Abstract:Background:
Excess flexion or extension during occipitocervical fusion (OCF) can lead to postoperative complications, such as dysphagia, respiratory problems, line of sight issues, and neck pain, but posterior fossa decompression (PFD) and OCF require different positions that require intraoperative manipulation.
Objective:
The objective of this study was to describe quantitative fluoroscopic morphometrics in Chiari malformation (CM) patients with sympto… Show more
