[Edit Diagnosis] [Merge dx] [Add prevalence]

Tags: Musculoskeletal Tag this Diagnosis.

The sensitivity and specificity of findings for Infraspinatus Tear are listed below. See the left navigation bar to change the display.

Pre-Test Probability (Prevalence): %. Post-Test Probability (Predictive Value): %. Switch to display mode.
**Note that calculating probabilities from more than one finding is inherently inaccurate because findings are not independent. (For example, using two positive findings that share a common pathogenesis is likely to overestimate the true probability.)
