The extensor carpi ulnaris tendon sheath is part of the triangular fibrocartilage complex (TFCC).
Palmer et al studied the anatomy and function of the TFCC through anatomical dissections and biomechanical testing. The TFCC was found to be composed of the sheath of the extensor carpi ulnaris (ECU), an articular disc, the dorsal and volar radioulnar ligaments, the meniscus homologue, and the ulnar collateral ligament. Biomechanically, they determined that the TFCC functions as a cushion at the ulnocarpal interface, and is a major stabilizer of the DRUJ.
Nakamura et al histologically examined the origins and insertions of the TFCC in fresh-frozen cadaver wrists. They found that the floor of the ECU sheath originated from the dorsal side of the fovea of the ulna, through an arrangement of Sharpey's fibers.

Platelet Rich Plasma (PRP) and Platelet Lysate Injection Treatments contain healing growth components from your own blood that increase your body’s natural ability to repair itself. The use of PRP to repair joint, tendon, ligament, and muscle injuries is becoming well known, thanks to exposure from professional athletes. Platelet injection treatments are effective because they have a stimulating effect on the stem cells within the targeted area, making those stem cells work harder to heal damaged tissues. Our Advanced Platelet Procedures are more pure and concentrated than those created by the automated machines used at most regenerative medicine clinics. Platelet procedures are commonly used for soft tissue injuries, mild arthritis and spine conditions.
Your wrist will be immobilized in a bulky dressing or cast. The type of immobilizing device used and the position your wrist is placed in depends on the type of surgery you had. Your surgeon may encourage simple finger and elbow motions soon after surgery.
Pain relief, improved motion, and increased function are the main goals of surgery for most patients. The surgeon is also interested in restoring wrist stability and the load bearing function of the wrist. After the initial soreness from the surgery is gone, you should experience a significant decrease in pain. Many patients report being pain free.
The follow-up plan after surgery may vary depending on the type of procedure used by your surgeon. Newer and improved methods have made it possible for some patients to return to full, unrestricted activity as early as six weeks post-op.
The standard surgery usually follows a typical course. One week after surgery, the splint will be replaced with a fiberglass type cast (still in a supinated position). The elbow is left free to move fully. The cast will be removed six weeks after the operation. Cast removal is followed by Physical Therapy for six to eight weeks.
