A self-locking pin for fixation of small bones and phalanges: a preliminary report.
In this preliminary report, a new self-locking pin for small bones and phalanges is presented. Its mechanical characteristics were tested and compared with those of a pair of crossed Kirschner wires in cadaver phalanges and with results presented in the literature. Extraction of the pin after callus formation was tested in vivo (on an experimental animal). The results prove the mechanical fixation efficiency of the single small-diameter self-locking pin and its easy removal from the new callus.
