To identify the biceps tendon:
- Patient with their hand resting on their lap. Palm upwards (external rotation) is best.
- Palpate the anterior humeral head (bicipital groove if you can) and place the probe transversely.
- Slide the probe superiorly and inferiorly to assess the entire tendon from the musculo-tendinous junction.
TIP: When you slide down, look for the pectoralis major tendon crossing over the biceps. This is the level of the bicipital musculotendinous junction. You must extend beyond this point to check for retraction if a tear is suspected.
