“…Our research contradicts that finding and it could be related to the fact that we looked at a larger series of patients. Similar to other upper cervical anatomical structures, which change with the increasing age, such as the atlantodental interval decreases with increasing age (15), these findings are not unexpected. It might be related to repeated and constant pull, twist, compression forces of the degenerating ligament similar to naturally increasing prevalence of degeneration, such as at the atlantodental joint (16).…”

“…In review of literature, a Chinese study on 700 patients reported mean AADI of 1.77 mm with SD of 0.39 mm. 14 The discrepancy in the values could be due to the demographic variation. The difference in the male and female values of AADI were statistically insignificant, which is in agreement with other studies.…”

“…The difference in the male and female values of AADI were statistically insignificant, which is in agreement with other studies. 11,14 We also found AADI levels to reduce as age advances, which was consistent with findings reported by Liu K et al 14 and Osmotherly PG 15 et al Pediatric age group (less than 18 years) has been reported to have a mean ADI of 2.25 mm (SD = 0.24 mm), 16 while we have found the mean AADI to be 1.89 mm (SD = 0.456 mm) in cases less than 20 years of age (►Table 3).…”

Objectives Craniovertebral junction (CVJ) is a unique, mobile and complicated component of our spine which necessitates specific study pertaining to its structure as well as pathologies. This study aims to report the normative data detailing the CVJ anatomy among the rural population of Central India which would help us in understanding the joint dynamics. Materials and Methods A retrospective observational study was undertaken in the Department of Neurosurgery and Radiology, Mahatma Gandhi Institute of Medical Sciences, Sewagram, Maharashtra, from December 2018 to May 2019. A total of 255 head injury patients with a normal CT brain cervical spine were included in this study. Anterior and posterior atlantodental interval (AADI/PADI), clivus length (CL), foramen magnum diameter (FMD), Boogard’s and basal angle (BOO & BA) were measured and analyzed. Statistical Analysis Statistical analysis was done using Microsoft Excel 2016. A web-based, open source application known as OpenEpi.com (version 3.01) was used for applying unpaired t-test. Results This study had a mean age of 42.9 years. The difference in mean value of AADI between male and female population was not found to be statistically significant, while in case of PADI, CL, FMD, BOO and BA, it was found to be significant (p < 0.05). On comparison of cases with age ≤ 20 years and > 20 years, we found the difference in values of ADI, CL and FMD to be statistically significant (p < 0.05). Conclusion Although there are some similarities, namely, AADI measurements as compared with other studies, there are differences in cutoff values of other parameters. Being a major draining reference center for rural population in India, this data can be extrapolated to a similar population for reference.

“…[13,14] Traditionally, C0-C2 relationship has been assessed by measuring of anterior atlanto-dental interval (ADI), posterior atlanto-dental interval (PADI), vertical atlanto-axial index (VAAI), basion-axial interval (BAI) and basion-dens interval (BDI). [15–18]…”

The Managment of cervical spine abnormalities in children with spondyloepiphyseal dysplasia congenita

et al. 2019

View full text Add to dashboard Cite

Spondyloepiphyseal dysplasia congenita (SEDC) is an autosomal dominant disorder, characterized by disproportionate dwarfism with short spine, short neck associated with variable degrees of coxa vara. Cervical cord compression is the most hazardous skeletal deformity in patients with SEDC which requires special attention and management.Ten patients with the clinical and the radiographic phenotypes of spondyloepiphyseal dysplasia congenita have been recognized and the genotype was compatible with single base substitutions, deletions or duplication of part of the COL2A1 gene (6 patients out of ten have been sequenced). Cervical spine radiographs showed apparent atlantoaxial instability in correlation with odontoid hypoplasia or os-odontoideum.Instability of 8 mm or more and or the presence of symptoms of myelopathy were the main indications for surgery. Posterior cervical fusion from the occiput or C1–3, decompression of C1–2 and application of autorib transfer followed by halo vest immobilization have been applied accordingly.Orthopedic management of children with spondyloepiphyseal dysplasia congenita (SEDC) should begin with the cervical spine to avoid serious neurological deficits and or mortality.

Reference ranges for atlantodental interval in adults and its variation with age and gender in a large series of subjects on multidetector computed tomography

Abstract: ADI measurements on MDCT linearly decrease with increasing age, and these are not affected by gender in adult patients. Different reference values might be used at different ages when diagnosing atlantoaxial anterior dislocation or subluxation.
