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.
