Bipolar prothesis

Due to high failure rate and complications associated with internal fixation, prosthetic replacement has been recommended by some authors as primary treatment for unstable intertrochanteric fractures [12] — [14].

The capsule was repaired followed by reattachment of the short external rotators to the femur. Cemented stems use acrylic bone cement to form a mantle between the stem and to the bone.

Both designs have shown excellent long-term durability when properly placed and are still widely used in slightly modified versions.

This approach gives excellent access to the acetabulum and femur and preserves the hip abductors and thus minimizes the risk of abductor dysfunction post operatively.

The hip consists of a ball and socket joint, the largest in the body, together with muscles, tendons, and ligaments, all of which keep the joint and affected bones in place. Copyright Fan et al. The trial stem was assembled with a trial cup, and reduction test was performed to determine the exact length of the prosthesis that would achieve equal limb length.

Doing the surgery from an anterior approach seems to lower dislocation rates when small diameter heads are used, but the benefit has not been shown when compared to modern posterior incisions with the use of larger diameter heads.

Abstract The present study was conducted to compare bipolar hemiarthroplasty BA with total hip arthroplasty THA in treatment of unstable intertrochanteric fractures in elderly osteoporotic patients. In order to get a clearer picture about the difference in their performance, we conducted the present study to compare the clinical effects of BA and THA in elderly osteoporotic patients with unstable intertrochanteric fractures, in terms of operation time, blood loss and transfusion, duration and cost of hospitalization, hip joint function, pain relief, general complications, and the rate of dislocation, revision and mortality.

Their incidence has increased due to the increased life expectancy and osteoporosis [1]. The inclusion criteria were: The interface size is measured by the outside diameter of the head or the inside diameter of the socket.

In order to get a clearer picture about the difference in their performance, we conducted the present study to compare the clinical effects of BA and THA in elderly osteoporotic patients with unstable intertrochanteric fractures, in terms of operation time, blood loss and transfusion, duration and cost of hospitalization, hip joint function, pain relief, general complications, and the rate of dislocation, revision and mortality.

When these are relieved with replacement surgery and normal motion and function are restored, the body feels that the limb is now longer than it was. As a result, patients that met the selection criteria were included. In most cases, the ends of the two bones, held in tight proximity to one another, such as in the elbows, fingers, or knees, make up a joint.

Ceramic heads are more smooth than polished metal heads, have a lower coefficient of friction than a cobalt chrome head, and in theory will wear down the socket liner more slowly. These plastic liners can crack or break free of the metal shell that holds them. All the patients underwent surgery with a standard posterior approach in lateral position under spinal or general anesthesia within 48 hours of admission.With an aim to satisfy our clients, we are engaged in offering an extensive range of Bipolar Hip Prosthesis.

These are manufactured using fine quality material and latest technology in compliance with industrial quality standards. These are used for hip surgery in case of severe damage in bone.

Additionally, we offer our products at reasonable prices.

Jun 22,  · The present study was conducted to compare bipolar hemiarthroplasty (BA) with total hip arthroplasty (THA) in treatment of unstable intertrochanteric fractures in elderly osteoporotic patients. What is a bipolar hemiarthroplasty? Treatment for femoral neck fractures can be successfully achieved through a bipolar hemiarthroplasty.

Hemiarthroplasty is a surgical procedure that replaces one half of the hip joint with a prosthetic, while leaving the other half intact. Dec 02,  · As indicated in the parenthetical note immediately following codethe appropriate code to report prosthetic hip replacement (eg, bipolar arthroplasty) following fracture of the hip, isOpen treatment of femoral fracture, proximal end, neck, internal fixation or prosthetic replacement (direct fracture exposure).

Unipolar And Bipolar - In some hip replacement procedures, bone is not actually replaced with a prosthetic device, but the ball of the femur is resurfaced, or the acetabular cavity is resurfaced, or both. When this is not a realistic solution, the ball, or tip of the femur may be replaced.

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.
