There could be a higher risk of postoperative C5 palsy in open door laminoplasty than double-door laminoplasty, according to a study published in Spine.
A total of 146 patients who underwent laminoplasty were examined for incidences of postoperative C5 palsy. The risk factors for C5 palsy were detected with multivariate logistic regression analysis.
Researchers found that postoperative C5 palsy occurred in 9.6 percent of the open-door laminoplasty cases and 1.4 percent of the double-door laminoplasty cases. Open-door laminoplasty was also recognized as having a significant risk for C5 paralysis.
The article suggests that because open-door laminoplasty requires an asymmetric decompression, an imbalanced rotational movement of the spinal cord could result in C5 laminoplasty.
