Operative Technique Step IV (Fig. 69) The Conical Extraction Rod is then threaded and tightend into the proximal end of the nail. The Lag Screw is extracted by anti-clockwise rotation and pulling of the Lag Screwdriver. The K-Wire must then be removed. Step V (Fig. 70a & b) An appropriate sliding hammer assembly is attached to the Extraction Rod and the nail extracted. Note: It is a useful to turn the Lag Screw Screwdriver clockwise slightly first to loosen the possibly bony ingrowth into the screw threads before turning it counter clockwise.

Operative Technique Dealing with Special Cases In the case of a comminuted fracture, there is a tendency for the fracture to become displaced posteriorly, making it difficult to place the K-Wire into the center of the neck and head. This can be solved by lifting the nail insertion Targeting Device (Fig. 71). Alternatively, an assistant can lift up the greater trochanter manually or with a reduction spoon; or support it with a sandbag. This will maintain the neck and the femur in almost the same axis, facilitating passage of the K-Wire through the center of the neck and head. Fig. 71 The position should then be checked in both the anterior-posterior and lateral views using the image intensifier. 39
