Connector for fractured bones

A connector for treatment of a fractured femur neck comprising:

• a sheath adapted to be inserted with its leading or front end through a bore made in the trochanter region, into the cavity of the femur head, the sheath being of a length sufficient to protrude out of said bore by a short length of its trailing or rear end, said front end being shaped to form at least three resilient tongues adapted to be forcefully expanded in an outward direction toward the cavity walls, by means of an expander head attached to the front end of a bar movable inside and along said sheath, said expander head being provided with three pivots, one pivot each being positioned opposite each of said tongues, each pivot holding the front end of a radially outswinging link, the rear end of said link being connected to a pivot positioned in the front end of the respective tongue, parallel to the pivot in said expander head, the rear of said sheath being provided with external screw threads interrupted by at least one flat surface extending along the sheath for a length not less than the length of the thread,
• means for moving said bar and said expander head in an axial direction, said means being provided at the rear end of said sheath,
• a shaft fixator comprising a flat plate provided with performations for attaching said plate to the femur shaft by means of screws, said plate being integrally connected to a socket provided with an opening corresponding in shape and size to the cross section of said flattened rear end of said sheath including an internally threaded nut mounted on said flattened end, the axis of said socket opening and said plate surface adjacent the femur shaft forming an angle of 116.degree.-136.degree., said socket being adapted to be moved along said sheath and to be biased against the outer bone surface by means of said internally threaded nut movable on said screw-threaded sheath end.
