PURPOSE: Morphology measures of the odontoid course of in youngsters below 12 years outdated had been carried out to reveal the viability of anterior inside fixation on this inhabitants as soon as their lively profile will not be appropriate with profitable conservative therapy.
METHODS: Throughout a 6-month interval, 36 tomographic examinations of the cervical backbone area that offered visualization of the odontoid course of had been chosen. Group 1 included youngsters between 6 and 9 years of age, and group 2 contained youngsters from 9 to 12 years of age. There have been 23 (63.eight%) male sufferers and 13 (36.2%) feminine sufferers. Sufferers identified with a tumor, an an infection, fracture non-union, or congenital malformation had been excluded. Exams had been ordered as a part of a protocol utilized to non-specific neck ache and pediatric trauma entries. The next parameters had been analyzed: (1) screw assault angle, (2) peak of the odontoid course of, and (three) minimal transverse diameter of the odontoid course of.
RESULTS: In Teams 1 and a pair of, the common values of the screw assault angle had been 55.9° ± 2.three° and 54.eight° ± Four.5°, respectively; the common heights of the odontoid course of had been 26.58 ± three.28 and 29.48 ± three mm, respectively, and the common minimal transverse diameter of the odontoid course of had been 6.57 ± 1.08 and 6.23 ± zero.88 mm, respectively. The minimal transverse diameter of the odontoid course of was statistically larger in males than that in females, no matter age (p = zero.007).
CONCLUSION: In each teams, the minimal transverse diameter of the odontoid course of allowed for the usage of one three.5-Four.5 mm screw for anterior inside fixation. These slides could be retrieved below Digital Supplementary Materials.
