An apparatus useful in reduction of fractures in the vicinity of the neck of the femur comprising a lag screw for being threadably received in or adjacent the head of the femur, and extending through the neck of the femur, an annular sleeve telescopingly receiving the shaft of the lag screw, with means capturing the lag screw within the sleeve for limited telescoping movement therein, and a trochanteric plate for securement to adjacent cortex portions of the femur is disclosed.

A dye injector apparatus is operatively disposed between a syringe containing an opaque dye suitable for x-ray photography and a cannulated screw or an orthopedic hip fixation device implanted in the ball head of a femur fractured at the femur neck. The dye injector comprises a cannulated shaft, a flange end suitably formed to receive the spout of the syringe, and a needle end suitably formed for insertion into the fixation device. The dye injector communicates the dye from the syringe to the cannulated screw. If the cannulated screw has extended beyond the femur ball head and penetrated the hip socket, an x-ray photograph of the hip socket shows the presence of the dye in the hip socket signaling the need for further operative care so that the cannulated screw will not postoperatively injure the hip socket.

A femoral insert combines bone ingrowth surfaces in the proximal portion of the shaft which is wide in the medial-lateral direction and curved in the medial aspect with a distal portion which has a round cross-section and is curved in the direction of the anterior bow of the femur. Accordingly, firm fixation of the implant is initially provided by the distal portion functioning as an intramedullary rod while long term stabilization is achieved proximally through bone ingrowth. Also, the neck connecting the spherical head to the shaft through the collar is anteverted with respect to the collar at an angle of about 10. degree. to 12. degree. The prosthesis for the left femur is basically a mirror image of the prosthesis for the right femur.
