Hair-thread tourniquet syndrome in an infant with bony erosion: a case report, literature review, and meta-analysis.

Hair-thread tourniquet syndrome is a rare condition where appendages are strangulated by an encircling strand of hair, a thread, or a fiber. The condition usually occurs in very young patients in the first few months of life. We present a unique case of a 3-month-old baby girl with hair-thread tourniquet syndrome in whom a hair cheese-wired through the skin and soft tissue of the toe and caused bony erosion of the underlying phalanx. An extensive literature review and meta-analysis of the topic are also presented.
