ORTHOPEDICS/SPORTS INJURIES/TENDONITIS
A tendon watershed zone is a tendon tissue section that obtains the weakest blood amount.
Watershed zones are important because they are the tendon zones that are disposed to damage.
Within hundreds of tendons in the body, yet we commonly see only a few tendon complications.
These complications kinds of tendonitis occur in the watershed zones of the tendon where the blood supply is poor.
The blood vessels that feed oxygen and nutrients must filter to the watershed zone through small capillaries.
This watershed zone relies on distant blood supply, and is therefore disposed to to damage.
Tendons with watershed zones that are disposed to tendonitis or tendon breaks comprise:
- Achilles tendon
- Rotator cuff tendon
- Posterior tibial tendon
- Tennis elbow
