What are the 2 components of a total hip prosthesis?
In the total hip replacement procedure, each prosthesis is made up of two major parts. The femoral component is a metal shaft with a ball on the end and replaces the top of the femur. The acetabular component replaces the socket side of the joint and is made of a metal cup and plastic liner.
What is a bipolar hip prosthesis?
Hemiarthroplasty means replacing the hip joint with a metal prosthesis. Unipolar prostheses has a one-piece design where the hip movement occurs between the prosthesis and the acetabulum (hip socket). A bipolar prosthesis has an additional artificial joint between the two components of the prosthesis.
What is the difference between a total hip arthroplasty and a bipolar hip arthroplasty?
THA is reportedly superior to BHA in terms of hip pain, function and reoperation rate. On the other hand THA has a higher rate of dislocation [2,3] while BHA is a less complicated surgery, has shorter operation time, less blood loss and lower initial cost [4].
What was the material used for hip implant analysis?
Cobalt chromium alloy (CoCr), titanium alloy, stainless steel are some of the most common hip joint materials used for hip implants.
What are the components of an artificial hip?
An artificial hip has three basic components: a stem that is inserted into the femur, a ball that attaches to the top of the femur and a cup that attaches to a socket in the pelvis.
What are the components of a total hip?
All of them consist of two basic components: the ball component (made of highly polished strong metal or ceramic material) and the socket component (a durable cup of plastic, ceramic, or metal, which may have an outer metal shell).
What is a bipolar component?
Bipolar disorder (formerly called manic-depressive illness or manic depression) is a mental disorder that causes unusual shifts in mood, energy, activity levels, concentration, and the ability to carry out day-to-day tasks.
What is a bipolar shell?
Partial hip replacement using Bipolar hip systems are a reliable and effective treatment option for hip fractures and diseased femoral heads and/or necks. The Bipolar shell articulates against the host acetabular articular cartilage, preserving acetabular bone stock for future considerations.
What do bipolar mean?
How long does a bipolar hip replacement last?
A successful hemiarthroplasty should last about 12 to 15 years or more.
What are prosthetic hips made of?
Nowadays hip joint prostheses are made with metals, ceramics and plastic materials. Most used are titanium alloys, stainless steel, special high-strength alloys, alumina, zirconia, zirconia toughened alumina (ZTA), and UHMWPE.
Which hip prosthesis is best?
The Taperloc femoral hip replacement is one of the best hip replacements used in the world – for any age and activity level. As the most successful titanium hip, the Taperloc femoral component has proven to stay firmly attached even after 28 years, allowing countless people to live life on their terms.
