Key result
Revision of failed hip hemiarthroplasty guided by a new classification system yielded a 93% success rate (15 of 217 required re-revision) at an average follow-up of 6.2 years.
Why the study?
Does a new classification system for failed hip hemiarthroplasty guide appropriate revision methods and lead to acceptable results?

Does a new classification system for failed hip hemiarthroplasty guide appropriate revision methods and lead to acceptable results?
A new classification system for failed hip hemiarthroplasty helps in choosing appropriate revision methods, achieving a 93% success rate at 6.2 years.
May inform revision planning in failed hemiarthroplasty; hypothesis-generating and requires prospective validation before practice change.
BACKGROUND: Many types of failed hemiarthroplasties have been reported, but there is no classification of these failures. PATIENTS AND METHODS: Revisions of 217 cases of failed hemiarthroplasty were studied with an average follow-up of 6.2 years. Classification system based on site of problem, mode of failure, and type of revision, was introduced. RESULTS: In most cases, the intra-operative assessment of failure correlated with the preoperative classification (99%). At the last follow-up, there were 15/217 re-revisions; giving a success rate of 93%. CONCLUSION: This classification helps in choosing the appropriate revision method, leading to acceptable results.

Morsi et al. (2016) conducted an observational in Failed hip hemiarthroplasty (n=217). Revision of failed hemiarthroplasty was evaluated on Success rate (absence of re-revision). Revision of failed hip hemiarthroplasty guided by a new classification system yielded a 93% success rate (15 of 217 required re-revision) at an average follow-up of 6.2 years.
