C1-C2 Transarticular Screw Fixation for Atlantoaxial Instability

Abstract

Transarticular C1-C2 screw fixation appears to be a safe and surgically reliable technique. Criteria for its application and refinements in its technical considerations continue to advance its clinically versatile therapeutic potential.

Outcome Comparison of Atlantoaxial Fusion With Transarticular Screws and Screw-Rod Constructs

“…3,19 One study of 12 SRC patients 25 and 4 studies comprising 74 TAS patients were performed in a prospective observational manner. 4,5,8,10,[13][14][15][16][17][18][20][21][22][23][24][26][27][28][29][30][31][32][33][34][35][37][38][39][40][41][43][44][45][46][47][48][49][50][51][52][54][55][56][57][58][59][60][61][62][63]…”

Reduction of displaced Hangman’s fracture by compression across crossed translaminar screws

“…4-6 A previously discussed technique is translaminar screw fixation due to both its effectiveness and relatively low rate of complications. [7][8][9] The presentation of our patient was complicated by a Type III odontoid fracture. Although there is no definitive treatment standard for a Type III odontoid fracture, many options have been used and range anywhere from conservative management to surgical intervention.…”

Posterior Atalntoaxial Fusion with C1 Lateral Mass Screw and C2 Pedicle Screw Supplemented with Miniplate Fixation for Interlaminar Fusion : A Preliminary Report

“…The fusion rate among the patients with fracture is higher with interspinous method suggested by Sonntag6). With transarticular screw fixation by Magerl, the fusion rate became higher from 82.6% to 100%5,8,15,19). C1 lateral mass and C2 pedicle screw fixation with polyaxial screw and rod system have been considered to show similar outcome with transarticular screw fixation11,17), however, to maximize the bone fusion rate of these technique, the combination with either a Gallie or a Brook's fusion is necessary28).…”
