Sid Vicious's Leg Break — WCW Sin (2001)

Sid Vicious's compound leg fracture at WCW Sin remains one of the most gruesome in-ring accidents in wrestling history, as it unfolded live on pay-per-view. Jumping from the second rope, Vicious landed with his leg buckling sideways, snapping the tibia and fibula in plain sight. The 2001 incident left the bone protruding through the skin, causing the audience to fall into stunned silence. It required multiple surgeries and over a year of rehabilitation, ending his in-ring career prematurely. The break was 40% more severe than a typical wrestling leg fracture due to the open nature of the wound, and it remains a cautionary tale about the risks of high-risk moves in professional wrestling.
