Summary

Functional posterior rhizotomy (FPR) improves locomotion and suprasegmental effects in children with spastic hypertonia. This surgical technique, introduced in Japan in 1996, shows promising future applications for spasticity treatment.

Neurosurgery
Pediatric Neurology

Background:

Functional posterior rhizotomy (FPR) is a surgical procedure for spastic hypertonia.
The modern technique was introduced to Japan in 1995 and gained recognition despite initial challenges.

Purpose of the Study:

To describe the history, surgical procedure, results, and future of FPR in Japan.
To evaluate the effectiveness of FPR in pediatric patients with spastic hypertonia.

Main Methods:

Surgical procedure based on Peacock's technique with modifications for ankle spasticity.
Operated on 98 patients (2-19 years old) with cerebral palsy and other conditions causing spastic hypertonia.
Utilized intraoperative neurophysiology to preserve function and guide root/rootlet selection.

Main Results:

17-83% of root/rootlets were abnormal and resected, correlating with disability severity.
Improved locomotion observed in 39% of patients followed for over a year.
Suprasegmental effects were noted in 59% of patients post-FPR.

Conclusions:

FPR is an effective treatment for spastic hypertonia in pediatric patients.
The role of FPR is expected to increase in Japan for managing spasticity.
