The Treatment Of The Avulsion Fracture Of The Finger By Percutaneous Kirschner Wire Blocking Ifxation:anatomic Study And Clinical Application

The avulsion fracture of the finger phalanx is common.The special characterof the fracture makes the treatment option few at present.The attachment points of tendons at both ends are important for the musclecontraction. The violence or unexpected contraction of the mucle can lead toavulsion fracture at the ending point. X-ray examination is often helpful for thecorrect diagnosis.Most avulsion fracture is intra-articular fracture, and the piece of the fractureis small,which makes the anatomic reduction particularly difficult.It was about20years ago that the treatment of the mallet fingers bypercutaneous kirschner wire blocking fixation was first reported.The case reportsof using the kirschner wire for the treatment of wilson fracture and the phalangealcollateral ligament avulsion fracture were published as well.The simplicity andeffectiveness of the method is verified.However, the Kirschner wire blocking fixation method has not been examedby systematic study.In this study, through the measurement of the radiation image data andphysical anatomy data we get the following conclusions：（1）The treatment ofthe avulsion fracture of the finger by percutaneous kirschner wire blockingfixation is effective（.2）The key for the success of the method is to choose anappropriate point for the wire.And using small incision for accurate fixationwas also advocated.
