R. Luchetti et al., SERIAL OVERNIGHT RECORDINGS OF INTRACARPAL CANAL PRESSURE IN CARPAL-TUNNEL SYNDROME PATIENTS WITH AND WITHOUT WRIST SPLINTING, Journal of hand surgery. British volume, 19B(1), 1994, pp. 35-37
In 15 carpal tunnel syndrome patients pressure was measured during the
day and at 2-hourly intervals from midnight to 6 a.m., via a catheter
introduced into the carpal canal, using the constant infusion techniq
ue. Intracarpal tunnel pressure of the patients always exceeded the cr
itical pressure of 30 mmHg and the highest values were found at 6 a.m.
Slightly lower pressures were found when the wrist was splinted, but
the difference was not significant, nor were critical pressure levels
prevented by splinting.
