A ceramic cup can not incorporate the lip that is a standard part of a plastic cup liner.
Ceramic head femoral.
Biolox forte and biolox delta ball heads and cup inserts can be combined with ceramic components from the biolox family of products as well as with inserts made from conventional and highly cross linked polyethylene.
P biomet offers both the biolox delta and the biolox delta option ceramic femoral heads.
Biolox delta ceramic femoral head.
The need for a low wear ceramic bearing in revision arthroplasty was not available in the past.
Avascular necrosis of the femoral bone head and fracture of neck and head of the femur.
This lip serves to lower the risk of dislocation.
Ceramic ball heads reduce polyethylene wear to significantly less than 0 1 mm per year.
11 the fatigue fracture in ceramic head with vulnerable design as well as obesity and squatting position during daily activity could be responsible in this patient.
Ceramic femoral heads have an advantage over cobalt chrome femoral heads for total hip arthroplasty according to a presented at the current concepts in joint replacement winter.
Below you will find an overview of the available sizes and many combination possibilities.
The biolox delta option ceramic head features a titanium neck sleeve designed to allow surgeons to utilize a ceramic head in either primary or.
Low wear with multiple liner options.
Head and stem combinations.
The titanium adapters have an internal 12 14 taper that mates with the femoral stem while the option heads have a taper designed to mate with the adapters.
The biolox delta component is a traditional one piece ceramic head indicated for primary hip arthroplasty only.
After surgical operations of osteosynthesis operation for restoration of joint function arthrodesis.
In revision cases a sleeved ceramic femoral head with a taper adaptor should be implanted.
The stress at the taper bore interface is decreased with a 28 mm short neck femoral head.
Thus 28 mm short neck ceramic heads also might be at a risk of fracture.
Non sleeved ceramic femoral heads should only be implanted on pristine non damaged stems.
In a few ceramic hip.
Therefore a ceramic on poly replacement has the advantage of the lip and a ceramic on ceramic has the advantage of being tougher and permitting the use of a larger femoral head.
