Recalcitrant carpal tunnel. The hypothenar fat pad flap.
Open decompression of the median nerve generally is so effective that little is mentioned of the surgical treatment options for recalcitrant or unrelieved carpal tunnel syndrome. The hypothenar fat pad flap has been shown to be a reliable local source of well-vascularized adipose tissue that can be used for coverage of the median nerve during re-exploration of recurrent or persistent idiopathic carpal tunnel syndrome. The hypothenar fat pad flap is a technically simple procedure that allows the fat pad to be mobilized easily and placed across the palm as a barrier between the nerve and the radial leaf of the transverse carpal ligament, effectively preventing median nerve readherence. This flap hopefully will improve the tissue environment for the median nerve, permitting it to have normal excursion during wrist motion. Our results to date have been better than previously described for other techniques. We believe the hypothenar fat pad flap should be considered in the hand surgeon's armamentarium for recalcitrant idiopathic carpal tunnel syndrome.
