Objective: Analyzing complications and risk factors for cervical vertebral body replacement (VBR) with expandable titanium cages.

Method: Data of 50 patients; 22 female and 28 male, mean age 61 years undergoing cervical VBR from 2010 to 2015 were analyzed. Complications were stratified by hardware association (HA). Univariate and multivariate logistic regression methods were used to identify independent risk factors.

Results: Single-, two and three level corpectomies were performed in 32, 15 and 3 patients respectively. A circumferential approach was necessary in 16 cases. At a mean follow-up of 7.3 months, 66% of patients had recovered. Radiological data showed a significant distraction (2.60 mm, p < 0.0001*) and lordosis (5° p = 0.001*). 23 patients experienced 42 complications, 18 HA, 24 non-HA and 24% needed revision surgery. The number of corpectomy levels and the surgical approach significantly correlated with the risk of complications (p = 0.001*) especially non-HA complications (P = 0.002*). Upon multivariate analysis, only the number of corpectomy levels (P < 0.02, odds ratio 5.48, 95% CI 1.31–22.91) was a significant predictor for complications.

Conclusions: Expandable titanium cages (ADD) are feasible devices for cervical spine VBR. When used for more than 1-level corpectomy, the complication rate significantly increases.
