66 patients (89 hands) were assessed at least 10 months after open car
pal tunnel decompression. Tender scars were found in 19% of the hands
and 4% were affected by pillar pain. Grip strength was reduced in more
than half of the operated hands. Hypo- and anaesthesia in the scar ar
ea were affecting 7% but were not considered disabling. In 18% of the
cases there was incomplete relief of primary symptoms.
