The phenomena persisted from periods of a few hours to two or three days, return of function being first noticeable in the sensory nerves, and often with modification in the way of lowered acuteness, or minor signs of irritation, such as formication, slight hyperæsthesia or pain, pointing to a combination with the least extensive degrees of hæmorrhage; later, motor power was rapidly regained.
No change except a deepening of the anæsthesia, and the development of formication on manipulation of the wound occurred, and at the end of three weeks the nerve was exposed (Mr. Watson), and it was found that
The early return of sensation, even if modified in acuteness, was always a very hopeful sign; also the production of formication in the area of distribution of the nerve on manipulation of the injured spot.
When in a position allowing of direct examination, the contused portion of the nerve sometimes developed a palpable fusiform thickening, manipulation of which might give rise to formication in the area of distribution -- a favourable prognostic sign.
The track was now hard and palpable, but there was no hyperæsthesia in any area; when the track was manipulated slight formication in the hand was experienced.
A fortnight later this pain still persisted; there was lowered sensation in the ulnar area with formication, also lowered sensation in the internal cutaneous area of distribution; sensation in the lesser internal cutaneous area was normal.
