OBJECTIVE: To evaluate the accuracy of inlet and outlet ultrasonography
measurements for the diagnosis of carpal tunnel syndrome (CTS). DATA SOURCES:
MEDLINE, EMBASE, the Cochrane Library, and the Web of Science databases were
systematically searched from inception to February 2017. STUDY SELECTION:
Observational studies comparing the diagnostic accuracy of inlet and outlet
ultrasonography measurements were selected. DATA EXTRACTION: Random-effects
models for the diagnostic odds ratio (dOR) values computed by Moses' constant for
a linear model and 95% confidence intervals (CIs) were used to calculate the
accuracy of the test. Hierarchical summary receiver operating characteristic
curves were used to summarize overall test performance. DATA SYNTHESIS:
Twenty-eight published studies were included in the meta-analysis. The pooled dOR
values for the diagnosis of CTS were 31.11 (95% CI, 20.42-47.40) for inlet-level
and 16.94 (95% CI, 7.58-37.86) for outlet-level measurements. The 95% confidence
region for the point that summarizes overall test performance of the included
studies occurred where the cutoffs ranged from 9.0 to 12.6mm(2) for inlet-level
measurements and from 9.5 to 10.0mm(2) for outlet-level measurements.
CONCLUSIONS: Both ultrasonography measurements for the diagnosis of CTS showed
sufficient accuracy for their use in clinical settings, although the overall
accuracy was slightly higher for inlet-level than for outlet-level measurements.
The addition of outlet and inlet measurements does not increase the accuracy for
the diagnosis. Therefore, the inlet-level ultrasonography measurement appears to
be an appropriate method for the diagnosis of CTS.
