Abstract

ARAUJO, Thiego Pedro Freitas et al. TOMOGRAPHIC STUDY OF THE S2-ALAR-ILIAC SCREW TECHNIQUE IN BRAZILIAN WOMEN. Coluna/Columna [online]. 2018, vol.17, n.4, pp.313-316. ISSN 2177-014X.  http://dx.doi.org/10.1590/s1808-185120181704179196.

Objective:

Lumbosacral fixation presents problems in its arthrodesis, mainly due to pseudoarthrosis. Iliac screws minimize this problem, however, they show problems in the operative wound. The S2-Alar-iliac (S2AI) screw presents a lower rate of these complications. The anatomical differences between the populations and the sexes analyzed in the literature justify the study of the S2AI screw technique in Brazilian women.

Methods:

A total of 14 adult female CT scans were analyzed by 4 evaluators.

Results:

The mean bone length was 131.8 mm, the largest bone diameter was 22.6 mm, and the smallest bone diameter was 22.6 mm.

Conclusions:

The data presented are compatible with the literature and may assist spine surgeons in choosing the best implant and surgical technique. Level of Evidence I; Diagnostic Studies — Investigating a Diagnostic Test (anatomical investigation).

Keywords : Spinal diseases; Surgery; Fracture fixation, internal.
