C-STEM™ Triple Taper-Stabilized Hip Total Hip Replacement

	Technological advances in hip replacement design and materials have resulted in sophisticated hip systems, such as the C-STEM™ Triple Taper-Stabilized Hip. The C-STEM Triple Taper-Stabilized Hip is designed to enhance stability and long-term durability, highly desirable for cemented total hip replacement The C-STEM Triple Taper-Stabilized Hip has an optimized profile, which helps lessen the chance of end-bearing stresses. End-bearing stress is
caused by too much weight being applied to the top of the stem at one time. The profile of the C-STEM Triple Taper-Stabilized Hip helps to distribute the weight evenly throughout the hip stem. This reduces end-bearing stresses and the risk of cement mantle fracture. The cement mantle is the wall of cement between the bone and implant.
How Does the C-STEM Triple Taper-Stabilized Hip Work?
The hip joint is one of very few true ball and socket joints of the body. The thick muscles of the buttock surround the back of the hip joint, while the thick muscles of the thigh protect the front.
	The hip socket is a deep cup that surrounds the ball of the upper thigh bone. The surface of the head of the thigh bone and the inside of the socket are covered with cartilage, a material that cushions the two joint bones from damage. When the cartilage begins to wear away, pain and stiffness result from bone rubbing against bone. Total hip replacement is a reliable procedure that can get you back to enjoying activities. A total hip replacement provides pain relief in 90 to 95 percent of patients, and most patients with stiff hips before surgery will regain effective motion
Why Choose C-STEM Triple Taper-Stabilized Hip?
The C-STEM Triple Taper-Stabilized Hip system can be implanted during any of the standard surgical approaches used for total hip replacement. The C-STEM Triple Taper-Stabilized Hip is a tapered stem. The stem begins narrow at the bottom, gradually becomes wider, and then narrows again at the top. This is called tapering and is what is responsible for the stem's unique shape. Its unique triple taper, neck shape, and profile help the implant achieve a more natural, anatomically correct distribution of weight to the thigh bone while reducing the potential for stress shielding. The system also minimizes the chances of late loosening. The distinctive triple taper design helps secure stability within the cement mantel from the moment of implantation through the life of the replacement. The geometric shape of the C-STEM Triple Taper-Stabilized Hip neck allows for a high offset option designed to achieve a closer anatomical match for patients with a higher-than-normal offset or a narrow femoral canal. to learn more. The high offset option also reduces the risk of dislocation and impingement for patients with a high offset and to balance weak inner-thigh muscles. It also allows stability to be restored with no increase in leg length. Offset helps to counterbalance any weight difference between the leg and the center of the body. The C-STEM Triple Taper-Stabilized Hip can also 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 liner. The PINNACLE Acetabular Cup System is designed to replace the socket portion (acetabulum) of the pelvis.
Who is a candidate for a C-STEM Triple Taper-Stabilized Hip?
Patients who have chronic pain and destructive arthritis of their hip joint and are unresponsive to other medical therapies are prime candidates for a total hip replacement using the C-STEM Triple Taper-Stabilized Hip system. On some occasions, the surgery is performed for other problems such as hip fractures or aseptic necrosis, a condition in which the bone of the hip ball dies. Most patients who have artificial hips are over 55 years of age, but the surgery is occasionally performed on younger persons. Circumstances vary, but generally patients are considered for total hip replacements if: Pain is severe enough to restrict not only work and recreation, but also the ordinary activities of daily living. Pain is not relieved by arthritis (anti-inflammatory) medicine, the use of a cane, and restricting activities. Significant stiffness of the hip. X-rays that show advanced arthritis, or other problems. Ask your MBO Specialist. Only an orthopedic surgeon trained in total hip replacement can provide advice about whether total hip replacement surgery using the C-STEM Triple Taper-Stabilized Hip is the option best suited to you.
Warnings and Precautions
Components labeled for "Cemented Use Only" are to be implanted only with bone cement. 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.
