A2 or A4 annular finger pulley tears are common injuries in rock climbers. This study reviews the measurement procedures used and tendon-to-bone distance data obtained on high-resolution ultrasound images when diagnosing isolated rupture of the A2 or A4 pulleys. Out of 3447 records extracted, only 7 remained after applying the exclusion criteria. In diagnosing a complete rupture, tendon-to-bone distance used varied widely from 1.9 to 5.1 mm for A2 and from 1.8 to 3.1 mm for A4. Our findings point to a lack of consensus diagnostic criteria for pulley injuries and identify technical details needing further research.
