- Abstract
- steolytic lesions due to wear debris are the major
long-term problem associated with total hip replacement1.
To avoid wear debris, hard-bearing-surface total
hip prostheses with improved tribological properties have
been introduced into surgical practice. Ceramic surfaces have
had some promising long-term results2, and modern metalbacked
alumina cups have been associated with very good
clinical results3-5.
Alumina has excellent tribological properties and a very
high Young's modulus that leads to very good compression
strength, but it has poor bending strength: it has no way to
deform6. This means that ceramic can break without warning.
Under normal physiologic conditions, modern ceramics never
reach their fatigue limit, so ceramic head fractures are rare (a
rate of 0.004%7 in one study). In contrast, ceramic liner fractures
are not well recognized, and their frequency could be
underestimated (Fig. 1). In addition, it is difficult to identify (literal)
