Bilateral Carpal Tunnel Syndrome

INTRODUCTION Carpal tunnel syndrome has been reported by some to have a less satisfactory outcome in older patients following surgery. However, this impression is not supported by other investigators but no objective explanation has been suggested for these differences. In our department, such patients are routinely treated with night wrist splints and, if this is unsatisfactory, they are investigated with nerve conduction studies prior to surgery. PATIENTS AND METHODS This paper reports the neurophysiological outcome in a young (< 40 years of age) and an older (> 60 years of age) group of patients with clinical bilateral carpal tunnel syndrome who did not benefit from splints. RESULTS The results showed that both the motor and sensory conduction speeds are significantly lower in the older age group. More importantly in the older group, half had one or more hands where the sensory conduction was absent. In four out of these 10 patients this finding was bilateral and three patients had unilateral absent motor conduction. In the younger group, no patient had absent conduction. CONCLUSIONS Poor surgical outcome in some older patients may be because of irreversibly damaged nerves prior to surgery and pre-operative neurophysiology is, therefore, recommended both for clinical and medicolegal reasons.

Operative Findings

Sensory conduction velocities of the median nerve before, during and after operation were compared in nine patients with carpal tunnel syndrome and four controls, in order to evaluate the prognostic value of the pre-operative and intra-operative findings. Sensory conduction velocity was higher after operation than before in all patients (mean difference 31.33%), but not in control subjects. One patient showed a dramatic increase of 157% immediately after decompression. Comparing the intra-operative with the post-operative findings all patients but one showed an increase of antidromic sensory conduction velocity (mean 44.37%), while in control subjects again minimal changes were found (mean –4.25%). The study confirms the high diagnostic value of the pre-operative antidromic sensory conduction velocity findings. However, the prognostic value of both pre-operative and intra-operative ASCV findings is low.

Sensory conduction velocities of the median nerVe were studied from digit to palm and from palm to wrist in normal subjects and in patients with the carpal tunnel syndrome. Definite slowing was noted in the palm to wrist segment, even in the early carpal tunnel syndrome. It was noted that 37% of normal women over 40 years of age had electrophysiological evidence of the carpal tunnel syndrome.
