Abstract

Objective

Cable closure has been introduced as a potential alternative to traditional wire cerclage (WC) for closure of median sternotomy. To evaluate whether cable closure improves patient outcomes, we conducted a systematic review and meta-analysis of the literature.

Methods

Ovid versions of Medline and Embase, and Google Scholar were used for the literature search. This yielded 7 studies (n = 2,758), which compared traditional WC to cable closure systems. Outcomes included deep sternal wound infection, sternal dehiscence, postoperative pain score, and sternal wound infection.

Results

We found significantly lower incidence of sternal dehiscence for cable closure compared to WC (risk ratio [RR] 0.14, 95% confidence interval [CI]: 0.03 to 0.59, P < 0.01, I ² = 0%) but no difference in DSWI (RR 0.97, 95% CI: 0.39 to 2.42, P = 0.95, I ² = 33%). Cable closure was also associated with lower pain when compared with the WC group (mean difference −1.04 points, 95% CI: −1.89 to −0.19, P = 0.02, I ² = 87%).

Conclusions

This study suggests that cable closure results in less incidence of sternal dehiscence and pain compared to WC. Nonetheless, there remains a limited number of studies on this topic and further high-quality studies are required to confirm the results of this meta-analysis.
