Now, significant studies have shown that C-spine immobilization, and specifically application of rigid C-collars, is a potentially dangerous practice.21 The reasons include: Recommendation Since the collar is under the chin and supports the chin, it minimises muscle contraction needed against the gravity forces to keep the head in a normal position .This type of collar does not truly immobilise the neck[2][3][4], it only limits flexion and extension in the end phase. 2014;18(3):429432.
