Introduction: Actually, many approaches have been
used in the surgery of the carpal tunnel, varying in size
and localization in the palm of the hand. Topographic points
in the palm of hand have been specifically chosen, with the
purpose of establishing fixed places of simple identification,
in order to obtain a place of easy access to the retinaculum
(RF), trying not to compromise any structure in the region
of the carpal tunnel.

Material and methodology: The authors of this work
have taken the technique used by Serra et al. (1997)(1) as a
basis, and have analyzed the anatomic study of this region,
in order to make the surgery of the carpal tunnel much more
accurate. To make it, they have dissected 20 hands, 10 right
and 10 left and operated on 10 pacients with Tunnel Carpal
Syndrome. Never mind the morphometric differences of the
different individuals.

Results: In all studied pieces , It had been identificated
an accurate point, named X, was achieved, so that from
this point on not only the distal edge of the RF has been
localized, but also the emergency of the branching of the
median nerve.

Conclusion: It had been observed in all the studied
cases the correspondence between the X point and the
emergency median nerve in the edge of RF.
