Purpose:
To provide the insight for postoperative hypotonia. Selective posterior rhizotomy (SPR) has been proved as a powerful tool for reducing spasticity. And also, its functional benefit and long-term effect are also well-known.
Results:
The most considered side effect of this procedure is postoperative hypotonia. However, some extent of temporary postoperative hypotonia can be the marker of the long-term success of this procedure. While the return of spasticity is the most unwanted side effect, some kind of overfitting, temporary postoperative hypotonia, can be the solution for that.
Conclusion:
For severely deformed patients, postoperative hypotonia may not be problematic, because severe spasticity makes them deformed and disabled. Deformed body will not show a definite disability from postoperative hypotonia.
