Provisional bone plate
View Patent ↗A provisional bone plate formed of an implantable plastic and having a length corresponding to the longest bone plate in a particular family of bone plates. The provisional bone plate includes a head contoured to match the head of a particular bone as well as a shaft for placement adjacent the bone shaft. The provisional bone plate includes a plurality of circumferential notches surrounding the elongate body or shaft of the bone plate. The circumferential notches are substantially transverse to a longitudinal axis of the bone plate and define frangible portions of the bone plate which can be removed from the distal end thereof to alter the length of the provisional periarticular bone plate to correspond to the length of the various bone plates in a family of bone plates. The provisional bone plate is constructed of a biologically suitable plastic, is radiographic, and melts at a temperature less than 200° Fahrenheit.
1. A method of choosing one of a family of bone plates for securement to a bone, comprising:
providing a provisional bone plate comprising:
an elongate body including a plurality of notches defining a plurality of frangible portions of the provisional bone plate;
determining whether the elongate body of the provisional bone plate is too long;
fracturing the bone plate along one of said plurality of notches and again determining whether the elongate body of the provisional bone plate is too long;
repeating the determining and fracturing steps until the provisional bone plate is no longer too long; and
choosing an implantable bone plate corresponding to the size of the provisional bone plate after the last fracturing step.
2. The method of claim 1 , wherein said provisional bone plate further comprises a plurality of size indicators positioned along said elongate body, and wherein said step of choosing an implantable bone plate comprises choosing an implantable bone plate corresponding in size to the largest size indicator remaining after the last fracturing step.
