Background
Dorsal rhizotomy is considered the gold standard for treating spastic diplegia/quadriplegia in children with cerebral palsy, when rehabilitation programs reveal insufficient to control excess of spasticity.
Method
The Keyhole Interlaminar Dorsal rhizotomy modality has been developed to access—individually—all L2–S2 roots, intradurally at the corresponding dural sheath, and preserve the posterior spine architecture. Intraoperative neuromonitoring consists of stimulating each ventral root, to verify its myotomal innervation, and dorsal roots, to explore their reflexive muscular responses in order to help determination of the proportion of rootlets to be cut.
Conclusion
This modality, which requires 5 ± 1 h duration, offers tailored accuracy.
