Platelet-Rich Plasma Injection Versus Hydrodissection in the Treatment of Carpal Tunnel Syndrome

whole blood is initially collected in tubes that contain anticoagulants, such as citrate dextrose A to prevent platelet activation prior to its use. Then PRP is prepared by a differential centrifugation. Then 3ml of PRP will be delivered via the in-plane ulnar approach

5ml will be injected to detach the median nerve from the TCL (2ml saline, 2ml dexamethasone and 1ml lidocaine), the injectate will be delivered via the in-plane ulnar approach, and the median nerve will be hydrodissected from its undersurface while advancing the needle among the superficial surface of the median nerve and the TCL
