2 Product Features BIOLOX delta ceramic heads are composed of 75% aluminum oxide and approximately 25% zirconia. The combination of these two materials provides low wear and higher strength as compared to alumina ceramics. 1 In addition, BIOLOX delta ceramic heads combined with Antioxidant Infused E1 bearings show wear rates similar to that of metal-on-metal articulations. 2 BIOLOX delta Option Ceramic Femoral Head Component The BIOLOX delta Option Ceramic Femoral Head is a two-piece component consisting of a titanium neck sleeve and a BIOLOX delta ceramic head. Unlike the traditional BIOLOX delta one piece ceramic head, which is indicated for primary arthroplasty only, the BIOLOX delta Option component is designed to allow surgeons to utilize a ceramic head in both primary and revision arthroplasty. 2.0 Volumetric Wear Rates of 38mm Acetabular Liners 2 5 Million Cycles 38mm Head Size Head Diameters Neck Sleeve Taper Neck Length mm 44mm Type I -6, -3, Std., +3, +6 12/14-3, Std., +4, +7 Volumetric Wear Rate (mm 3 /MC) BIOLOX delta/ E1 Liner Metal-on-Metal (Run-in Wear) Type 1-6mm -3mm Std +3mm +6mm 1

3 Instructions for Use BIOLOX delta Option ceramic femoral heads and titanium neck sleeves are compatible with Biomet Type 1 and 12/14 stem tapers and can be utilized in both primary and revision total hip arthroplasty with Biomet polyethylene and antioxidant infused liners. Head Removal In the case of a revision surgery, extraction of the existing femoral head should be done with suitable extraction instruments to avoid unnecessary damage to the trunnion. Figure 1: Taper with scratch/defect at a height of 0.25mm Stem Trunnion Inspection The BIOLOX delta Option Ceramic Head component can be used on both a new stem, or a previously implanted stem. BIOLOX delta Option Ceramic Head components should not be used on trunnions with scratches or defects greater than 0.25mm in height. Inspect the taper for damage prior to placement of the modular head components by measuring scratches or defects, verifying that the height is less than 0.25mm (Figure 1). Figure 2: Taper with broad truncation The conditions shown in Figures 2, 3 and 4 are also considered unsuitable for the use of the Biomet BIOLOX delta Option Ceramic Head and can be expected to cause failure. Figure 3: Slanted taper Biomet does not practice medicine. Each surgeon is responsible for determining the appropriate device and surgical technique to utilize on each individual patient.

4 Trialing Verify the taper type on the existing stem or the stem to be inserted, taking care to select the correct trial and final implant that matches the stem taper. Determine the appropriate neck length and verify joint stability. Assembly Instructions Verify the correct selection of BIOLOX delta Option Ceramic Head and neck sleeve as predetermined during the trialing process. Any neck sleeve can be used with any BIOLOX delta Option Ceramic Head. Note: Heads and neck sleeves are packaged separately. Assemble the modular head components prior to positioning them onto the stem by aligning the head onto the neck sleeve axially and apply pressure. A slight resistance will be felt once the taper is engaged (Figure 5 & 6). Figure 5 Head/Stem Positioning Assure that all tapers, neck sleeve to ceramic head and ceramic head component to stem trunnion, are clean and dry before assembly. Impact the modular head components onto the stem with a light tap that firmly and definitively seats the head using a plastic head impactor only. Note: The use of metal impactors or any other metallic objects may scratch or crack the modular head bearing surface, compromising the integrity of the component. If the modular ceramic head becomes scratched or cracked, the head and neck sleeve must be replaced. Figure 6 To verify fixation of the head, attempt to remove the head by hand. 3

Box 587 Warsaw, Indiana USA Date: 11/09 lta Option Modular Head Hip Join Biomet Biolox delta Option Modular Head Hip Joint Prostheses ATTENTION OPERATING SURGEON DESCRIPTION The Biomet Biolox delta Option Ceramic modular head components are a Transition- Toughened-Platelet Alumina Composite ceramic (TTPA) material with highly polished surfaces in a variety of head sizes. The highly polished surface is designed to reduce friction and minimizes wear. The titanium sleeves adapt the ceramic heads to either a Biomet Type I or a Biomet 12/14 taper and allows them to be used in both primary and revision total hip arthroplasty. Taper with scratch/defect at a Height of 0.25mm Figure A Taper with Broad Truncation Figure B MATERIALS Head - TTPA Ceramic Sleeve - Titanium Alloy (Ti-6Al-4V) INDICATIONS 1. Noninflammatory degenerative joint disease including osteoarthritis and avascular necrosis. 2. Rheumatoid arthritis. 3. Correction of functional deformity. 4. Treatment of non-union, femoral neck fracture and trochanteric fractures of the proximal femur with head involvement, unmanageable by other techniques. 5. Revision procedures where other devices or treatments have failed. CONTRAINDICATIONS Absolute contraindications include: infection, sepsis, and osteomyelitis. Relative contraindications include: 1) uncooperative patient or patient with neurologic disorders who are incapable of following directions, 2) osteoporosis, 3) metabolic disorders which may impair bone formation, 4) osteomalacia, 5) distant foci of infections which may spread to the implant site, 6) rapid joint destruction, marked bone loss or bone resorption apparent on roentgenogram, 7) vascular insufficiency, muscular atrophy, or neuromuscular disease. WARNINGS Improper selection, placement, positioning, alignment and fixation of the implant components may result in unusual stress conditions which may lead to subsequent reduction in the service life of the prosthetic components. Malalignment of the components or inaccurate implantation can lead to excessive wear and/or failure of the implant or procedure. Inadequate preclosure cleaning (removal of surgical debris) can lead to excessive wear. Improper preoperative or intraoperative implant handling or damage (scratches, dents, etc.) can lead to crevice corrosion, fretting, fatigue fracture and/or excessive wear. Use clean gloves when handling implants. Laboratory testing indicates that implants subjected to body fluids, surgical debris or fatty tissue, have lower adhesion strength to cement than implants handled with clean gloves. Do not modify implants. The surgeon is to be thoroughly familiar with the implants and instruments, prior to performing surgery. 1. Use Biomet Biolox delta Option ceramic modular head with Biomet metallic femoral components. Do not use Biomet Biolox delta Option ceramic modular heads with femoral stems or acetabular components offered by other manufacturers. Mismatching of components or taper sizes can be expected to cause intraoperative or postoperative fracture of ceramic heads. 2. Sleeves labeled Type I Taper are to be used with femoral stem components labeled Type I Taper. 3. Sleeves labeled 12/14 are to be used with femoral stem components labeled 12/14 taper. 4. Use only with Ultra-High Molecular Weight Polyethylene (UHMWPE) or metal-backed UHMWPE acetabular components. 5. Do not use ceramic heads that have been dropped, rubbed, scratched, or disfigured. Blemishes can be expected to cause failure. 6. Do not use a metallic hammer when seating the ceramic head. Use a nylon or polyethylene seating instrument. Do not use excessive force. The TTPA ceramic head can fracture with excessive force. 7. The femoral stem trunion, sleeves and the bore of the ceramic head should be dry and free of contamination prior to assembly. 8. During a revision surgery, extraction of the femoral head should be done with suitable extraction instruments to avoid unnecessary damage to the trunion. 9. Biomet Biolox delta Option modular head components should not be used on trunnions with scratches or defects greater than 0.25mm in height. The surgeon should inspect the taper for damage prior to placement of the modular head components by measuring, with a measuring device, any scratches or defects, and verifying that the height is less than 0.25mm (see Figure A). The conditions shown in Figures B, C and D are also considered unsuitable for the use of the Biomet Biolox delta Option Ceramic Head and can be expected to cause failure: 10. Patient smoking may result in delayed healing, non-healing and/or compromised stability in or around the placement site. Slanted Taper - Figure C Crushed Taper - Figure D Biomet joint replacement prostheses provide the surgeon with a means of reducing pain and restoring function for many patients. While these devices are generally successful in attaining these goals, they cannot be expected to withstand the activity levels and loads of normal healthy bone and joint tissue. Accepted practices in postoperative care are important. Failure of the patient to follow postoperative care instructions involving rehabilitation can compromise the success of the procedure. The patient is to be advised of the limitation of the reconstruction and the need for protection of the implants from full load bearing until adequate fixation and healing have occurred. Excessive, unusual and/or awkward movement and/or activity, trauma, excessive weight, and obesity have been implicated with premature failure of certain implants by loosening, fracture, dislocation, subluxation and/or wear. Loosening of the implants can result in increased production of wear particles, as well as accelerate damage to bone making successful revision surgery more difficult. The patient is to be made aware and warned of general surgical risks, possible adverse effects as listed, and to follow the instructions of the treating physician including follow-up visits. PRECAUTIONS Specialized instruments are designed for Biomet joint replacement systems to aid in the accurate implantation of the prosthetic components. The use of instruments or implant components from other systems can result in inaccurate fit, sizing, and/or excessive wear and device failure. Intraoperative fracture or breaking of instruments has been reported. Surgical instruments are subject to wear with normal usage. Instruments, which have experienced extensive use or excessive force, are susceptible to fracture. Surgical instruments should only be used for their intended purpose. Biomet recommends that all instruments be regularly inspected for wear and disfigurement. Do not reuse implants. While an implant may appear undamaged, previous stress may have created imperfections that would reduce the service life of the implant. Do not treat patients with implants that have been, even momentarily, placed in a different patient. Patient selection factors to be considered include: 1) need to obtain pain relief and improve function, 2) ability and willingness of the patient to follow instructions, including control of weight and activity levels, 3) a good nutritional state of the patient, and 4) the patient must have reached full skeletal maturity. POSSIBLE ADVERSE EFFECTS 1. Material sensitivity reactions. Implantation of foreign material in tissues can result in histological reactions involving various sizes of macrophages and fibroblasts. The clinical significance of this effect is uncertain, as similar changes may occur as a precursor to or during the healing process. Particulate wear debris and discoloration from metallic and polyethylene components of joint implants may be present in adjacent tissue or fluid. It has been reported that wear debris may initiate a cellular response resulting in osteolysis or osteolysis may be a result of loosening of the implant. 2. Early or late postoperative infection and allergic reaction. 3. Intraoperative bone perforation or fracture may occur, particularly in the presence of poor bone stock caused by osteoporosis, bone defects from previous surgery, bone resorption, or while inserting the device. 4. Loosening, migration, or fracture of the implants can occur due to loss of fixation, trauma, malalignment, malposition, non-union, bone resorption, and or excessive, unusual and/or awkward movement and/or activity. The trunnion must also be free of scratches or defects greater than 0.25mm in height, free of slants, free of broad truncations, and free of crushed ends (see warning #9 for clarification). 5. Periarticular calcification or ossification, with or without impediment of joint mobility. 6. Inadequate range of motion due to improper selection or positioning of components. 7. Undesirable shortening of limb. 8. Dislocation and subluxation due to inadequate fixation, malalignment, malposition, excessive, unusual and/or awkward movement and/or activity, trauma, weight gain, or obesity. Muscle and fibrous tissue laxity can also contribute to these conditions. 9. Fretting and crevice corrosion can occur at interfaces between components. 10. Wear and/or deformation of articulating surfaces. 11. Trochanteric avulsion or non-union as a result of excess muscular tension, early weight bearing, or inadequate reattachment.

The TTPA ceramic modular head is composed of ceramic material with limited clinical history. Although mechanical testing demonstrates that, when used with polyethylene acetabular components, ceramic balls produce a relatively low amount of particles, the total amount of particulate produced remains undetermined. Because of the limited clinical and preclinical experience, the long-term biological effects of these particulates are unknown. 14. Intraoperative and postoperative bone fracture and/or postoperative pain. 15. Ceramic head fractures have been reported. Manufacturer Symbol Legend ASSEMBLY INSTRUCTIONS 1. The modular head components must be assembled together before positioning them onto the stem. 2. Verify that the appropriate head size and matching tapers are being utilized before assembly. 3. The modular head components are assembled by placing the head onto the sleeve as shown in Figure E and Figure F.
