UNIT FOR RESETTING BONE FRACTURE CAUSED BY PYRAMIDAL COMPRESSION

摘要

An object is to prevent cement leakage into the extrapyramidal tract, thereby protecting the living body from undesirable effects. It is intended to provide a unit for resetting bone fracture caused by pyramidal compression (1) comprising an inlet tube (2) whereby the front end is introduced into a space in the pyramid (C) via a through hole (B) formed in the pedicle of vertebral arch (A), a balloon (3) made of an elastic filmy material which is detachably attached to the front end of the above-described inlet tube (2) and can be inserted in the deflated state into the pyramid (C) via the through hole (B) and inflated in the pyramid (C), and a cement (4) which is supplied into the balloon (3) through the inlet tube (2), wherein the inlet tube (2) is provided with an air vent part(6) for discharging air enclosed in the inlet tube (2) and the balloon (3).
