What is the Zimmer Biomet G7 made of?
The hemispherical design of the G7 acetabular shell provides fixation and stability with proven1–7 PPS Porous Plasma Spray Coating or OsseoTi Porous Structure. Multiple bearing options are also available, including E1 Antioxidant Infused Technology, ArComXL Polyethylene and BIOLOX® delta ceramic liners.
What is Biomet G7?
Simplicity, Efficiency, Performance From simple primary to complex revision arthroplasty, Zimmer Biomet’s G7® Acetabular System is a modular system offering a comprehensive portfolio of shell, fixation and bearing options to establish a stable joint in THA.
What is an acetabular shell?
A metal shell for bony ingrowth + a polyethylene liner (sometimes metal or ceramic) that snaps into the shell and articulates with the femoral head.
What is dual mobility hip replacement?
“Dual mobility” refers to the bearing surface of the implant – where the joint surfaces come together to support one’s body weight. The hip is a ball-and-socket joint, and a hip replacement prosthesis is designed to simulate a human hip joint.
What are acetabular cups made of?
The acetabular cup itself or its insert can be made of plastic, ceramics, a combination of plastic and ceramic or lastly metal as with hip resurfacing.
What does a total hip replacement consist of?
Description. In a total hip replacement (also called total hip arthroplasty), the damaged bone and cartilage is removed and replaced with prosthetic components. The damaged femoral head is removed and replaced with a metal stem that is placed into the hollow center of the femur.
Which is the best hip replacement material?
Ceramic-on-metal Ceramic is one of the best materials that can be used in a hip replacement, but when paired with a metal socket it quickly falls to the back of the pack. Keep in mind that any metal particles in your bloodstream could lead to long-term health problems.
Is there a recall on Zimmer hip replacements?
FDA recently announced a Class I designation for a Zimmer hip replacement parts recall. Certain Zimmer M/L taper with Kinectiv technology femoral stems and necks have “unexpected amounts of manufacturing residues” that can cause serious adverse health issues, including death, according to the agency.
Can you ever cross your legs after hip replacement?
You shouldn’t cross your legs or, if you’ve had a total hip replacement, you should not roll the surgical leg inward or outward. DO NOT pivot on your affected leg. If you need to turn while walking, fully stop and lift your foot to change direction.
Which method of hip replacement is the best?
The posterior approach to total hip replacement is the most commonly used method and allows the surgeon excellent visibility of the joint, more precise placement of implants and is minimally invasive.
What are femoral stems made of?
The femoral stem is the portion of the replacement that fits into your thigh bone. Historically, this is made from titanium and/or cobalt-chromium metals. In the modern era of hip replacements, cemented stems (inserted with a surgical bone cement) are composed of cobalt-chromium metals.
Why is the G7 acetabular shell hemispherical?
The hemispherical design of the G7 acetabular shell is intended to provide fixation and stability as demonstrated by clinical results1–7with PPS® Porous Plasma Spray Coating or OsseoTi Porous Structure.
What is the size of the G7 acetabular system?

Why do the G7 screw holes allow 15 degrees of variability?
This will ensure the appropriate screw direction can be achieved. The G7 screw holes allow approximately 15 degrees of variability. Screws oriented outside this range may result in incomplete seating of the screws and prominent screw heads within the shell, which could impede insertion of the liner.
Why choose G7 liners?
Increased ranges of motion, as found in the Freedom constrained liner at 114 degrees, have been clinically shown to reduce the risk of impingement and instability 12 Stability Interchangeability between all G7 components allows surgeons to customize stability to the patient’s needs
