Hey Hippyu
To address your subject: I do not believe that is the case. Ceramics prosthetics for total hip have been through several decades of development (currently in their 4th generation) and current ceramics have a very good track record. Ceramic fractures are very rare. Less than one in a thousand. And fractures are often in the liner not the actual ceramic.
Do a few searches on pubmed (
https://pubmed.ncbi.nlm.nih.gov/) or take a look at these papers:
Incidence of Ceramic Fracture in Contemporary Ceramic-on-Ceramic Total Hip Arthroplasty: A Meta-analysis of Proportions. December 17, 2019 DOI:https://doi.org/10.1016/j.arth.2019.12.013
Ceramic-on-ceramic bearing fractures in total hip arthroplasty: an analysis of data from the National Joint Registry PMID: 28768777 DOI: 10.1302/0301-620X.99B8.BJJ-2017-0019.R1
Small head sizes (usually 28mm or so) and heavier patients have a greater risk of fracture. But that head size is found in total hip arthroplasty. Not resurfacing.
I'm only speculating on what I've read but I believe if the prosthetic does crack it is dealt with rapidly (as the patient typically can't walk on it). And revisions are performed on them. But you should speak to your surgeon about this if you have questions.
As this site is focused on hip resurfacing you may actually be referring to ceramic on ceramic hip resurfacing and not replacement(?) In that case there really isn't any data yet on fractures with CoC resurfacing.
However, consider that the resurfacing CoC prostheses (there are two currently in trials) will be fourth generation, that there is actually no ball involved (your own femoral ball is resurfaced and would not be anywhere near 28mm, usually 40-60mm depending on the sex and size of the patient) and that patients typically have lower BMIs than total hip patients. Ceramic fracture will probably be even less likely with CoC resurfacing.
My two cents anyway
Cheers.
