A multi-pin pin impactor and method of use are described. The pin impactor includes a body which can be held by a user and manipulated to re-position the pin impactor during use. First and second pin holders are attached to the body and each include a pin release mechanism effective to releasably retain a pin within the pin holder. An impaction can have a force applied to apply a driving force to a one of the pins. In use, a first pin held by the pin impactor is introduced into an aperture in a surgical instrument mounted on a bone. A force is applied to the pin impactor to drive the first pin into the bone. The orientation or position of the pin impactor is changed to introduce a second pin held by the pin impactor into a second aperture in the surgical instrument without re-loading the pin impactor and a force is applied to the pin impactor to drive the second pin into the bone.
