[Reconstruction of first web space of hand: follow-up analysis of 40 cases]

The follow-up outcome of 40 cases after reconstruction of the first web space of hand was reported. Of them, the hand function was improved in 31 cases, not improved in 6 cases, and worsened in 3 cases. The authors thought that the pedicled ilio-inguinal axial flap for treatment of first web space defect is one of the reconstructive methods for choice in spite of its bulky appearance. Though the operative method of the dorsal local skin flap of hand is simple, it may interfere with the flexion of MP joint of the index finger and the reconstructed first web space is very deep and not plumpy. The author proposed that the extent of the reconstructed first web space should depend upon the patient's occupation, and that the function of internal muscles of the hand and of the flexion and extension muscles of thumb should be taken into consideration because too large a first web space may interfere with the function of opposing finger.
