3 X A C T I N S T R U M E N TAT I O N Exact Hip Instrumentation was developed by Biomet engineers to address the needs of today s orthopedic community. The end result is a revolutionary concept in femoral component instrumentation that not only promotes intraoperative flexibility, but also meets the demands of efficiency, simplicity and consolidation. Versatile Exact General Trays 1 & 2 are used in the implantation of hips from Biomet s Alliance Family, Mallory-Head Family or Taperloc System. Just add the appropriate broach/reamer/trial trays to General Trays 1 & 2. Intraoperative Flexibility By providing common general instruments for Biomet hips, Exact Hip Instrumentation provides unparalleled intraoperative flexibility and familiarity for use in all primary and revision situations. Precision Instrument Design Exact Hip Instrumentation has been designed with the most advanced CAD-CAM technology for optimal femoral canal preparation. Precision Implant Fit Computer-Aided Design (CAD) combined with net forging technology to enhance implant-to-bone fit. The first intra-family instrumentation system designed with the most advanced CAD-CAM engineering technology available.

4 C O N E X A C T H I P I N S Exact Hip Instrumentation Versatility in its original form. J L K I H F E D Exact General Tray 1 was designed to simplify preoperative setup, as well as address the most common instrumentation needs found in primary and revision hip arthoplasty. Basic insertion needs for X-Series hips in the Alliance Family as well as the Mallory-Head Porous Primary and Taperloc Porous Primary are met with a single tray. The versatility of General Tray 1 is evident in the variety of instruments that will B A G A. Calcar Planer; B. Offset Hollow Chisel; C. Exact Broach Handle; D. 1/8 x 1/4 Twist Drill; E. Starter Reamer; F. Exact Universal Bone Plug Inserter; G. Distal Canal Sizer; H. Femoral Inserter with Modular Forks; I. Femoral Inserter/Extractor; J. Universal Femoral Head Driver; K. T-Handle; L. Exact Spring- Loaded Calcar Planer. share one space in the tray. For example, surgeon preference is maximized as any one of the five different stem insertion handles that Biomet manufactures will fit into a single slot in General Tray 1. Several other instruments in the tray offer this same flexibility. C

Special emphasis has been placed on items that are most often used at the time of component extraction and revision. A B C A. Modular Head Removal Tool; B. Slap Hammer; C. Offset Punch; D.

6 E X A C T H I P I N S System Specific Instrumentation A System specific broach trays like this one for the Mallory-Head Porous Primary, feature nitride-coated broaches to extend the life of the cutting teeth. Each tray will also house the system s neck trunions, resection guide and broach handle. B The benefits and flexibility of General Trays 1 and 2 are realized with the surgeon s selection of a femoral component. Instrument trays containing broaches, reamers and trials specific to that femoral component are used in conjuction with General Trays 1 & 2. These trays are color-coded for easy identification and more efficient surgical use. Incremental, system specific head/neck trunions allow for proper reproduction of anatomic offsets and leg length. These improvements at trial reduction will allow up to 21 degrees greater range of motion, and reduce head/neck trial inventory by more than 80%. C A. System specific tapered reamers and universal cylindrical reamers offer unparalleled flexibility for femoral canal preparation. Depth calibrations that correspond to the Exact templates are etched proximally on the tapered reamer; B. These calibrations are based upon the head center to the tip of the stem Cylindrical reamers also incorporate depth calibrations to assist in a variety of different primary and revision applications; C. Gold trunions represent the Standard offset, while blue trunions represent the Lateralized offset. V E

The combination of these trays, along with General Trays 1, 2 and the Exact cylindrical reamers will provide instrumentation needs for all primary and revision situations.

8 T E C M A N U F A C T U R E D W I T H Meticulous design combined with improved manufacturing techniques has allowed for advanced concepts in femoral component and instrumentation design. Recent developments in three-dimensional solid modeling technologies allow for designs to be viewed and manipulated from all angles. The improved technology promotes accurate interpretation of compound planes and complex implant geometries, leading to the precise and consistent development of femoral components and related instrumentation. This innovative manufacturing technology will enhance surgical efficiency and patient satisfaction.

State-of-the-art technology has allowed for a revolutionary new tooth pattern for the broaches to contour the femoral canal more precisely. H N O L O G Y

Net forging technology will provide for a more precise fit for the implant. The human variability associated with previous manufacturing methods is greatly reduced, allowing for superior reproduction of the compound angles on the finished implant. The Exact templating system offers a very precise mode for implant sizing and preoperative evaluation of anatomic offset. Vertical and medial scales correspond to appropriate reamer and resection guides to aid in leg length restoration. Tables are included on each template for quick offset reference.

X-Series implants refer to specific porous components found in the Alliance Family of Hips. Biomet has been successful in optimizing a consistent press fit in correlation with the multiple geometries and configurations in the Alliance Family. Designed for use with Exact Hip Instrumentation, X-Series implants maximize the effectiveness of net-forging technology while maintaining the specific features that surgeons prefer. This advanced technology will capitalize on the excellent clinical results 1 8 of tapered stem geometries that are available to the surgeon to meet virtually every indication for hip reconstruction in cementless applications.
