Though widely reported, Hair-thread Tourniquet Syndrome (HTTS) is poorly recognized. It refers to external, mechanical, circumferential constriction of an appendage, typically with an end-artery such as a digit, resulting in a "compartment syndrome-like" situation. HTTS is illustrated using the case of an infant. Children presenting with irritability should have their digits examined for signs of strangulation, with the awareness that numerous strands may be involved, with some buried in the skin. Early surgical-release must be performed if unwinding or simple cutting is unsuccessful.
