Stripe Wear Ceramic Head

Ceramic on ceramic hip retrieved for squeaking.
Stripe wear ceramic head. The determination of femoral head stripe wear magnitude and ceramic liner fracture propensity involved a multistep approach previously described. Stripe wear has been reported in many ceramic on ceramic hip replacement retrievals and microseparation separation of the femoral head from the acetabular cup has been proposed as one suggested. Metal transfer from the cup is also apparent. Ceramic microseparation can lead to edge load ceramic head wear and squeaking.
The femoral head demonstrated a characteristic stripe wear pattern and the overall volumetric wear rate was high 19 mm 3. 5 out of 5 stars 402 402 reviews 10 00. Stresses developed during hip articulation with or without the occurrence of component impingement were determined from a global dynamic fe model of tha mechanics. Stripe wear has been reported in first second and third generation alumina bearings in which it has been associated with steep cup angles young patients and revision surgery 19 27.
The aim of this in vitro study was to investigate whether different angles of inclination influence the wear pattern of alumina on alumina hip joints with micro separation during the swing phase. 5 out of 5 stars 102 102 reviews 3 49.

Has a unique complication of stripe wear occurring from lift off separation of the head gait. Ceramic bearings have the lowest wear rates of any bearing combination 0 5 to 2 5 µ per component per year ceramic on polyethylene bearings have varied ranging from 0 to 150 µ.
