A Birmingham Hip Resurfacing (BHR) prosthesis is a medical device used for partial hip replacement surgery. The Birmingham Hip Resurfacing device is used to provide stability and mobility for patients with hip pain and joint deterioration. The implant contains two parts, both made of Cobalt-Chromium alloy. The top portion of the implant is spherical, which looks like half of a ball, with a thin cylindrical stem that branches out of the spherical piece. The parts are the acetabular cup and the femoral head.
Discussion
Acetabular Cup The acetabular cup is a part of a partial hip prosthesis that is inserted into the acetabulum, or hip joint and used as a socket. The acetabular cup provides stability for the rest of the device. The acetabular cup in figure 1, is made out of Cobalt-Chromium alloy, it is shaped like half of a hollow sphere. The specific dimensions depend on the patient, the diameter of the piece ranges

The femoral head functions as biomechanical support for the patient needing a hip implant. The femoral head is Cobalt-Chromium alloy, which is sliver and lustrous. The top portion of the part is half of a hollow sphere, which fits inside of the acetabular cup. Out of the middle of the half sphere, is a short cylindrical stem. The diameter of this piece depends on the size and weight of the patient; it ranges from 38- 58 mm. The femoral head is in figure 2.
Conclusion
A Birmingham Hip Resurfacing (BHR) prosthesis is a medical device used for partial hip replacement surgery. The Birmingham Hip Resurfacing device offers mechanical reinforcement for patients with hip pain. The BHR contains a acetabular cup and femoral head. The Birmingham Hip Resurfacing medical device helps improve
