OBJECTIVE: To propose new sonographic criteria for the diagnosis of idiopathic
tarsal tunnel syndrome (TTS). DESIGN: Prospective case-control study. SETTING:
Academic referral center. PARTICIPANTS: Adult healthy volunteers (n=17) and adult
patients (n=14) with electrodiagnostically proven idiopathic TTS (mean age,
43.4+/-8.7y; height, 161.4+/-7.0cm; weight, 90.6+/-13.9kg)
(N=31). The exclusion
criteria were patients with diabetes, neurological disorders, associated ankle
and/or foot disorders, electrodiagnostic evidence of a widespread lesion, or feet
that were electrophysiologically negative for TTS or with structural
abnormalities detected via ultrasound imaging. INTERVENTIONS: Not applicable.
MAIN OUTCOME MEASURES: Tibial nerve CSA at the proximal tarsal tunnel, tibial
nerve CSA within the tunnel, within tunnel-to-proximal tunnel CSA ratio. RESULTS:
There was a significant difference in the within tunnel CSA and within
tunnel-to-proximal tunnel CSA ratio between the TTS group and controls (P=.002
and P=.001, respectively). The optimum cutoff value was 19mm(2) for the within
tunnel CSA and 1 for the within tunnel-to-proximal tunnel CSA ratio.
Sensitivities were 61% and 74%, respectively.
CONCLUSIONS: The within
tunnel-to-proximal tunnel CSA ratio and the within tunnel CSA are the most
accurate sonographic parameters and can be helpful in the assessment of
idiopathic TTS.
