Exception Cementless Hip Stem

Total hip arthroplasty (THA) is a common operative treatment where an arthritic, degenerative or fractured hip joint is replaced with a prosthetic device if conservative options are unable to relieve pain and debilitating symptoms. THA was traditionally performed on patients over 60 years old, but now includes young and active patients, as well as very old ones thanks to the continuous improvement in implant design. Major indications of THA include osteoarthritis, rheumatoid arthritis, avascular necrosis and hip fractures. The THA surgical procedure involves replacing the head of the femur and acetabulum or socket with an artificial prosthesis. This system is composed of a femoral stem that is inserted into the femoral canal, a ball that attaches to the femoral stem, and an acetabular component or shell that replaces the acetabulum.
