The apparatus in accordance with claim 1, further comprising at least one surgical pin adapted to be temporarily inserted through at least one aperture in at least one of said head portion and said elongated body portion, said surgical pin being adapted to position said bone plate relative to the bone. 9. The apparatus in accordance with claim 1, further comprising at least one fastener adapted to be inserted through at least one aperture defined in said head portion for attaching said head portion to the fractured distal portion of the bone. 10. The apparatus in accordance with claim 1, further comprising a fastener adapted to be inserted through an aperture defined in said flex tab for attaching said flex tab to said at least one of the shaft portion of the bone proximate the fractured distal portion of the bone and the fractured distal portion of the bone. 11. The apparatus in accordance with claim 1, wherein said at least one alignment tab is adapted to position said bone plate on the bone. 12. The apparatus in accordance with claim 11, wherein said at least one alignment tab projecting from said head portion is further adapted to attach together comminuted fractured portions of the fractured distal end portion of the bone. 13. The apparatus in accordance with claim 11, wherein said at least one alignment tab is flexible through a range of acute angles with respect to at least one of said elongated body portion and said head portion. 14. The apparatus in accordance with claim 13, further comprising a fastener adapted to be inserted through an aperture defined in said at least one alignment tab oriented in the range of acute angles, for attaching said at least one alignment tab to the bone. 15. The apparatus in accordance with claim 1, wherein said bone plate is further adapted for fixation and reduction of a malunion of a distal portion of the bone. 16. The apparatus in accordance with claim 1, wherein said bone plate is adapted for fixation and reduction of at least one of a fractured distal radius, a fractured distal tibia, a fractured distal femur, a fractured proximal humerus, a fractured metacarpal, a fractured proximal phalange, a malunion of a distal radius, a malunion of a distal tibia, a malunion of a distal femur, a malunion of a proximal humerus, a malunion of a metacarpal, and a malunion of a proximal phalange. 17. A method for fixation and reduction of a fractured distal portion of a bone, comprising: utilizing a bone plate comprising: an elongated body portion adapted for attachment to a shaft portion of the bone, said elongated body portion defining a longitudinal axis extending substantially parallel to the shaft portion of the bone;a head portion connected to said elongated body portion, and projecting therefrom at a first angle with respect to the longitudinal axis, said head portion adapted for attachment to the fractured distal portion of the bone;at least one alignment tab projecting from a perimeter of at least one of said head portion and said elongated body portion; anda flex tab connected to a surface of an opening defined in said head portion and extending substantially parallel to the longitudinal axis, having an inner surface adapted to be pivoted into contact with, and to be attached to, at least one of the shaft portion of the bone proximate the fractured distal portion of the bone and the fractured distal portion of the bone;aligning said head portion on the fractured distal portion of the bone, such that said elongated body portion projects away from the shaft portion of the bone at an angle corresponding to the first angle;pivoting said flex tab into contact with the at least one of the shaft portion of the bone proximate the fractured distal portion of the bone and the fractured distal portion of the bone;attaching said flex tab to the at least one of the shaft portion of the bone proximate the fractured distal portion of the bone and the fractured distal portion of the bone;attaching said at least one alignment tab to the bone;attaching said head portion to the fractured distal portion of the bone;applying pressure to said elongated body portion to bring said elongated body portion into contact with the shaft portion of the bone; andattaching said elongated body portion to the shaft portion of the bone. 18.
