Hip Replacement Parts - Stem & Sockets
|
Each hip replacement consists of a stem and a socket. Either stem or socket can
be inserted into the patient's body with or without cement. Using modern techniques,
material science and proven implants; both cemented and uncemented hip replacements,
have functioned extremely well. Loosening of the components is quite uncommon.
The bearing surface or articulating surface is where the stem meets the socket.
There is a ball / head attached to the stem, which articulates with the socket as
the hip moves. Classically the head has been made of metal and the socket made of
ultra high molecular weight polyethylene (special plastic)
Alternative articulating surfaces are available.
Ceramic heads
Ceramic heads have been used to articulate with ceramic cups, these have been shown
to have extremely low wear rates.
Metal heads
Metal heads have been used to articulate with metal polished cups with very good
wear rates.
Oxynium heads
There have been new technologies in material science, oxynium is a particular metal
alloy that is used to make the head / ball which then articulates with ultra high
molecular weight polyethylene (special plastic sockets).
Which Hip Replacement is Best for You?
The specific type of hip replacement that is best suited for a particular patient
is highly dependant on the patient. Therefore, the final decision is individually
tailored to the patient's situation.
