Episode notes
Shoulder Anatomy Variability
- Shoulder anatomy varies not just in size but also in shape and offsets.
- Fixed relationships exist between humeral head diameter, thickness, and inclination angle variability.
Advantages of Stemless Implants
- Stemless shoulder implants allow independent placement of the humeral head.
- This enables exact restoration of head position without needing offset heads.
Non-Spherical Native Humeral Heads
- Native humeral heads are non-spherical with superior-inferior diameter greater than anterior-posterior.
- Using spherical heads risks rotator cuff damage and requires undersizing to avoid impingement.
