Dealing with “short” nerve roots. A : The impression of shortness is spurious; these functional and supple roots appear short because they were bound tightly to the inner lining of the dura by adhesion bands that are being cut. B : After having been detached from the inner lining of the dura, these “short” nerve roots become magically “lengthened”.
