Case Reports[Anatomical study and clinical application of transfer of pronator quadratus branch of anterior interosseous nerve in the repair of thenar branch of median nerve and deep branch of ulnar nerve].
In order to obtain the anatomical basis of transferring the anterior interosseous nerve to repair the injury of thenar or ulnar nerve at the wrist level, ten fresh cadaveric forearms were dissected. The pronator quadratus branch of the median nerve was (1.5 +/- 0.4) mm in diameter with (866 +/- 144) nerve fibers. The recurrent branch of median nerve was (1.7 +/- 0.3) mm in diameter with (1,120 +/- 97) nerve fibers. ⋯ On electromyogram it was normal in 10. The myodynamia was restored in different degree: M2 in 2, M3 in 5, M4 in 7, M5 in 3. The procedure of the operation and the matters needed attention during the operation were discussed.

[Experimental study on the collateral sprouting after end-to-side anastomosis of nerve trunk].
In order to observe the collateral sprouting capacity of the nerve trunk after end-to-side anastomosis, a window was made on the epineurim of the donor nerve through which the result of the end-to-end anastomosis of nerves could be compared. Sixteen SD rats were chosen and divided into 4 groups randomly. Group 1, the peroneal nerve was severed, the epineurium of the tibial nerve was fenestrated and sutured the peroneal stump with the tibial nerve by end-to-side neurorrhaphy. ⋯ Even in Group 3, there were plenty of nerve fibers turned into tiny myelined nerve fibers through collateral sprouting. But the ChAT activity in Group 1 was only two thirds of that in Group 4. It was suggested that the epineurial sheath did not influence the collateral sprouting of the nerve.
