Platelet-rich Plasma Injection for Ulnar Neuropathy at Elbow

Ulnar neuropathy at elbow (UNE) is the second common peripheral entrapment neuropathy after carpal tunnel syndrome (CTS). Although many conservative managements of UNE were found, their effectiveness were often unsatisfied without existed guideline. Recently, the perineural injection of 5% dextrose wate (D5W) is a novel management for CTS but its effect for UNE is not obviously as CTS. Hence, it is very important to find another novel injectate for UNE.
