Design outcomes
Primary
| Measure | Time frame |
|---|---|
| To evaluate the pulley function of the hook of the hamate, the curvature radii of the little and middle finger flexor tendons at the hook of the hamate were calculated based on the visualized flexor tendons on ultrasound images. In addition, changes in these radii with extension and flexion of the fingers were examined. | — |
Secondary
| Measure | Time frame |
|---|---|
| The position of the little finger flexor tendon was determined regarding the height of the hook of the hamate as 100%.Furthermore, changes in the positions of the flexor digitorum profundus and superficialis tendons with extension and flexion of the fingers were examined. | — |
