Many etiologies of tarsal tunnel syndrome exist, but it is difficult t
o determine the specific etiology for a patient. Surgical success rate
s vary in the literature from 44% to 100%. This retrospective study re
viewed 40 patients with 45 data sets. Thirty-five patients (87.5%) in
the study were female; 35 patients (87.5%) were caucasian. Thirty-two
feet (71.1%) showed improvement following the tarsal tunnel surgery. T
he Tinel's sign parameter improvement was statistically significant, T
he differences in the subjective parameters of burning, radiating, and
sharp sensations were statistically significant, while the difference
s in pins and needle sensation were nearly significant. The Takakura i
ndex and its constituent parameters were all statistically significant
postoperatively with the exception of muscle atrophy, which did not h
ave sufficient data for testing.
