Amputation

Amputation is the removal of a body extremity by trauma or surgery. In some cases, it is used as a threat or as a form of torture or punishment.

Day 1
In the first hours of Day 1, Jack Bauer and Richard Walsh were ambushed at 2350 Dunlop Plaza. To escape, Jack cut off the finger of a dead guard to use for the fingerprint identifications of the building security system.

Day 2
During Day 2, Kim Bauer and his boyfriend Miguel where arrested for being suspects of the murder of Carla Matheson. To help Kim escape, Miguel started a fire in the police car. This caused a car crash and Kim had to leave Miguel trapped inside. As a result of the crash, Miguel had to have his right leg amputated. This prompted him to leave Kim without telling her about it.

Day 3
At the end of Day 3, Chase Edmunds pursued Arthur Rabens to prevent him from detonating a mechanism loaded with the Cordilla virus inside a school. During a fistfight with Rabens, Chase cuffed the mechanism to his hand to prevent Rabens from taking it, but not before he activated the detonating mechanism. As time ran out and they found no way to deactivate the mechanism, Chase convinced Jack to cut off his hand. Jack did so with an ax and took the mechanism to a safe place where it detonated. Later, Chase was treated at St. Thomas Hospital where he had his hand reattached.

Day 6
During Day 6, CTU found out that the Russian consul in Los Angeles, Anatoly Markov, was complicit in the terrorist events of the day. Jack Bauer invaded the Russian consulate and tried to force Markov to surrender the location of his fellow conspirator, Dmitri Gredenko. To make him talk, Jack cut one of Markov's fingers and he eventually surrendered Gredenko's location.

Later, Gredenko was captured by CTU and forced to help them capture the mastermind of the terrorist attacks, Abu Fayed. To achieve this, they planted an isotope device on Gredenko's arm to track his location. Gredenko then met with Fayed at the Santa Monica Pier but informed him of the device. Using a nearby saw, they cut off Gredenko's arm and left it behind while they escaped. Eventually, Gredenko betrayed Fayed but died of blood-loss under the pier.

Day 7
During Day 7, First Gentleman Henry Taylor was kidnapped by Iké Dubaku and his men. Dubaku threatened to kill Taylor if his wife, President Allison Taylor, didn't abort the invasion of Sangala. To convince her he was serious, Dubaku had one of his men, Elemu, cut one of Taylor's fingers.
