Neurologic TOS with amyotrophy is exceptional and the diagnosis is
usually delayed compromising the outcome after treatment. The aims of this study
were to define clinical features, anatomical causes, surgical results and
prognostic factors of this disease. METHODS:
All of the TOS with objective
neurologic deficit treated in our unit between 1989 and 2011 were assessed
retrospectively. Thirty cases were identified in 28 patients (two bilateral
cases). The mean-age was 44 years (16 to 70). RESULTS: Muscular atrophy always
predominated in the lateral thenar muscles. Seventeen also had sensory symptoms.
Twenty-two patients (24 cases) were surgically treated. Twenty-three cases could
be assessed with a mean follow-up of 39 months. Recovery was complete in four
cases (17%), marked in nine cases (39%) and minimal in ten cases (44%).
CONCLUSIONS: Neurological TOS with objective manifestations have to be
distinguished from other types of neurological TOS. Muscular atrophy in the hand
appears insidiously and the pain, which is inconstant, stays always in the
background. Duration of symptoms before surgical treatment is the main prognostic
factor.
