ABSTRACT:
A bone marrow cavity fixation device for treating a fractured bone is composed of a tubular body, a plurality of diameter-adjusting elements, an adjustment element, and an urging element. The tubular body is provided axially with a hollow interior and is further provided peripherally with a plurality of through holes communicating the hollow interior with the outside of the tubular body. The diameter-adjusting elements are disposed movably in the through holes such that the diameter-adjusting elements can be so urged by the adjustment element located in the hollow interior as to jut out of the through holes to bring about an increase in diameter of the tubular body. The adjustment element can be actuated by a rotational motion of the urging element which is located in the hollow interior such that the top end of the adjustment element is urged by the lower end of the urging element. The diameter-adjusting elements are provided respectively with a retaining element engageable securely with the retaining device of the tubular body or the adjustment element.
