 | The S-ROM® Modular Hip System offers many advantages for people who need either a first-time (primary) total hip replacement or revision hip surgery to replace an existing hip implant. The S-ROM Modular Hip System is modular, which means the parts that make up the joint come in different sizes and can be positioned in different ways. This flexibility makes the S-ROM Modular Hip System helpful for either primary or revision surgery. It also allows the surgeon to fit each new hip to fit a patient's individual needs. |
| The Distinctive Benefits of the S-ROM Modular Hip System |
- Adaptable parts that have been used successfully for more than 18 years
- Flexibility that allows the surgeon to correct problems such as uneven leg length or bad alignment of the leg and the hip
- A system that works well in patients in various age groups or with osteoporosis (bone loss)

| How do Cementless Implants Work? |
The S-ROM Modular Hip System is cementless - instead of relying on bone cement to hold the new hip in place, S-ROM Modular Hip System uses the body's own tissue growth and holding powers. To understand how this works, it helps to
first understand the structure of the hip. |
 | The hip joint is like a ball that fits in a socket. The socket part of the hip is called the acetabulum. The S-ROM Hip System may be used in conjunction with the Pinnacle™ Acetabular Cup System. The PINNACLE Acetabular Cup System is made up of a metal component and a polyethylene or metal liner. The PINNACLE Acetabular Cup System is designed to replace the socket portion (acetabulum) of the pelvis. The ball is called the femoral head, because it sits at the top of the femur - the long bone that runs |
| from the hip down through the thigh. In an artificial hip, the femoral head is on top of a femoral stem. This stem is inserted inside the femur bone, connecting the leg to the hip. With cementless surgery, the femoral stem does not require cement. The S-ROM Modular Hip System has raised "fins" that keep the implant from twisting or spinning. It also utilizes a sleeve (or collar), which provides added stability. The surface of the sleeve is rough and porous (has many small holes and spaces in it). This roughness encourages new tissue from the femur to grow right into the implant surface, holding it securely in place. This process is called tissue ingrowth. Tissue ingrowth may provide a better, more reliable bond than cement. |
| Why Choose the S-ROM Modular Hip System? |
The highly flexible S-ROM Modular Hip System offers advantages for patients with complex surgical needs. Because of its design, it is an excellent implant for the active, high-demand patient.- The S-ROM® TAILOR-FIT™ System
The S-ROM Modular Hip System offers more customizing options than any other modular hip implant.1 As a result, the surgeon can select and position the parts of a new hip in order to create the most natural leg length and leg alignment possible for each individual. This way allows for ease of movement after surgery. It is especially valuable in cases where joint damage or a previous hip replacement makes surgery more complicated.
- A Machined Bone Fit
The precision tools in the S-ROM Modular Hip System let surgeons match the shape and size of the opening in the femur exactly to the shape and size of the implant that's best for each patient. An exact fit encourages strong, lasting tissue ingrowth into the surface of the implant.

| What are the Results with the S-ROM Modular Hip System? |
Doctors have had excellent results with the S-ROM Modular Hip System since 1984.1 One study involved 159 patients whose average age was 59. Some of these patients had both hips replaced, so 175 S-ROM Modular Hip System implants were studied for up to 7.8 years. The results include: - Over 99% of all S-ROM Modular Hip System hips remained stable and secure after an average of almost five years of follow-up with X-ray studies.
- The researchers concluded that these findings indicate: "this implant works very well in patients regardless of age or degree of osteoporosis (bone loss).

| Who is a Candidate for the S-ROM Modular Hip System? |
| The S-ROM Modular Hip System is especially well suited to the needs of active patients. 4 It is designed to offer solutions for people who are having either a first-time (primary) hip implant or replacement (revision) hip surgery. Revision surgery may be needed when an existing implant has loosened because of continuing disease and bone loss. The most common causes of hip disease leading to primary hip replacement or revision surgery are: - Degenerative joint disease (also known as DJD or osteoarthritiss).
- Rheumatoid arthritis.

| Warnings and Precautions: |
| The following conditions tend to adversely affect hip replacement implants: excessive patient weight, high levels of patient activity, likelihood of falls, poor bone stock, metabolic disorders, disabilities of other joints |
| Adverse Events: |
| The following are the most frequent adverse events after hip arthroplasty: change in position of the components, loosening of components, fracture of components, dislocation, infection, tissue reaction. |
