Hypothenar fat-pad flap

Abstract

The treatment of scarring of the median nerve in the carpal tunnel following open carpal tunnel release, trauma,or infection presents the hand surgeon with a difficult problem,since adhesions between the nerve and scar tissue in the tunnel impair its longitudinal mobility.Measured in specimens,this amounts to between 7 and 14 mm in a longitudinal direction [1, 2] and some dorso-palmar and radio-ulnar excursion also [3, 4].In some cases the median nerve is even prolapsed and scared between the two ligamentous stumps of the flexor retinaculum after open carpal tunnel release. © 2007 Springer-Verlag Berlin Heidelberg.
