What is the difference between unipolar and bipolar hemiarthroplasty?
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. Both treatments are clinically proven and common around the world.
Is Austin Moore unipolar?
Due to higher rate of complications in osteosynthesis, arthroplasty is a preferred treatment. Hemiarthroplasty can be done using uncemented unipolar Austin Moore prosthesis and cemented bipolar arthroplasty.
What is a cemented bipolar hip arthroplasty?
This surgical procedure replaces the head of a damaged femur with an implant designed to stabilize the femur and restore hip function. Unlike total hip replacement, in which both the ball of the femur and the hip socket are replaced, in this procedure, only the ball is replaced.
What is cemented hemiarthroplasty?
Hip hemiarthroplasty (HHA) is a common treatment for hip fractures in the elderly population. Because of the fatal effects of bone cement implantation syndrome, the safety of cement utilization to enhance implant firmness in the femur is controversial.
What is difference between total hip replacement and bipolar hemiarthroplasty?
Total Hip Arthroplasty is reportedly superior to Bipolar Hemiarthroplasty in terms of hip pain, function and reoperation rate. Total Hip Arthroplasty has a higher rate of dislocation rate than Bipolar Hemiarthroplasty.
What is Charnley classification?
Charnley stated: ”1. Class A consists of patients with only one affected hip and no other condition interfering with walking. 2. Class B consists of patients with a bilateral hip disease, but the rest of the body normal and therefore not responsible for any defect in ability to walk.
What is a hemi hip arthroplasty?
OVERVIEW. Hip hemiarthroplasty is a procedure used to treat hip fractures that is like a total hip replacement but only part of the hip is replaced. While this procedure is used to treat hip fractures, it is also used to treat hip arthritis. The recovery process is very similar to that of a total hip replacement.
Why is cemented bipolar hemiarthroplasty?
Cementing the prosthesis affords more secure fixation and may result in less postoperative midthigh pain and a reduced long-term revision rate (loosening is less). For decades, the optimal treatment choice has been debated, and whether cemented is better than uncemented hemiarthroplasty remains uncertain.
Does bipolar hemiarthroplasty have hip precautions?
Your Physical Therapist will also review the movements that you must avoid doing to protect your hemiarthroplasty (also called the hip precautions). These movements are dangerous as they can cause your hip to dislocate. The risk of dislocation is greatest right after surgery.
