The O'Brien and the Gaul techniques can repair, amongst the various non-microsurgical methods to reconstruct the tip of the thumb, any kind of loss of integumental tissue of the palmar aspect in the distal phalanx. The O'Brien method uses two neurosensitive island flaps obtained on both collateral palmar pedicles. This flap can be used in losses of tissue of the far end of the fingertip whose length is less than 2 cm, regardless of the conditions of the nail bed and root. Whenever the loss of tissue is larger than 2 cm it is possible to use the neurosensitive cross-finger flap obtained from the dorsal surface of the proximal phalanx of the index finger (Gaul's technique). This technique requires a second operation to detach this flap (supplied by the radial nerve) from the donor area and to transfer it to the tip of the thumb. The Authors discuss the use of these techniques with indications and explanation of the main surgical steps. They have used 10 such flaps with a good outcome even in the presence of infection.
