INTRODUCTION Like the art of fine woodworking, the Novation® Comprehensive Hip System design began with the end in mind. Before launching into development, Exactech’s engineers and design team surgeons established a comprehensive plan. Their goal: to provide a system of femoral stems, acetabular components and surgical instrumentation that would address any situation encountered during primary total hip replacement. They let science be their guide and conducted an extensive research review to identify the best of the best in design and materials. These proven features were blended with...

PRE-OPERATIVE PLANNING Tools choice is approximately at the center of rotation of the templated acetabulum. Note: Most of the time the chosen prosthetic head (neck length) does not line up with the center of rotation of the acetabulum or even with a mark in the center of the femoral head.The appropriate lateral offset, either Standard or Extended, can be recorded at this time. The head usually is positioned proximal and medial to the center of rotation of the acetabulum. In effect, at the end of the operation the surgeon will be pulling on the limb and lifting the prosthetic femoral head...

Detailed OPERATIVE TECHNIQUE Approach and Exposure The Novation femoral stems are compatible with any standard surgical exposure. In this operative technique, the posterior lateral approach is described. Dislocation and Osteotomy A. Hip Dislocation The hip should be dislocated by flexion, adduction and internal rotation. Placing a bone hook around the femoral neck may help in difficult cases. Soft tissues along the intertrochanteric line to the proximal border of the lesser trochanter should be cleared. When tight, the gluteus maximus tendon may be released to improve exposure. The limb...

B. Broach Assembly/Disassembly The Element Broach Handle is assembled to the Element Broach by pulling back the trigger while inserting the rectangular body of the Element Broach Handle into the superior aspect of the Broach and releasing the lever (Figure 4). Care should be taken to ensure that the assembly of the instruments is correct. C. Femoral Broaching Broaching is performed with progressive broach sizes, beginning with the smallest Broach. The Broach is inserted into the femoral canal in a few degrees of anteversion (Figure 5). The surgeon should alternate impaction and withdrawal...

D. Calcar Preparation (Optional) Calcar planing can be performed, if desired, in order to remove any bone that protrudes above the level of the impacted Element Broach by guiding the Calcar Planar Assembly into the hole on the interior surface of the broach attachment opening (Figure 6). Calcar Planar Blade Replacement - If necessary, a Replacement Calcar Planar Blade can be used to ensure proper removal of excess bone. Use the Calcar Planar Blade Removal Tool to remove the used blade, replace it with a new blade and tighten with the Removal Tool. Trial Reduction A. Trial Component...

Final Reduction A. Femoral Stem Insertion Figure 8 Femoral Stem Insertion The appropriate femoral stem is chosen and assembled to the Offset Stem Inserter. The femoral stem is impacted taking care to ensure correct rotational alignment, version and depth (Figure 8). It may be necessary to allow the bone to adapt to the implant as it is being impacted. Another trial reduction can be performed with the final femoral stem and Femoral Head Trial. B. Femoral Head Impaction The taper of the femoral stem should be clean and dry. The selected femoral head component is placed onto the taper of the...
