Abstract

Abstract Background Total Hip Arthroplasty (THA) is one of many therapies given to hip joint injury patients. The main indication for THA in elderly patients is degenerative diseases of the joints. One of the difficulties encountered in this THA procedure is to overcome the acetabulum deficiency, with Paprosky Classification. This study aims to evaluate patients with acetabulum defect that have undergone THA at Dr. Soetomo Hospital in 2014–2016. Methods This was an observational retrospective study with descriptive analysis. The sample amount was 20 patients, from 80 patients who had THA procedure. Patients were evaluated based on the wear from acetabulum, migration from a cup, the presence of bone loss, heterotopic ossification, and also clinical condition based on Harris Hip Score. The presented results were analyzed by using Kruskal-Wallis on SPSS 19.0 for Windows Program. Results Hypothesis testing was performed on THA patients based on acetabulum defect type I, II, and III in one, two, and three years after surgery respectively. Massin Score resulted no differences with p = 0.156, p = 0.574, and p = 0223. Bone Loss Classification resulted no differences with p = 0.296, p = 0.287, and p = 0223. No difference on Wear Rate with p = 0.072, p = 0.110, and p = 0.325. There was no difference of Harris Hip Score with p = 0.320, p = 0.082, and p = 0.472. Conclusion There were no significant differences in radiological evaluation of the Migration Rate, Heterotopic Ossification or Bone Loss, Wear Rate, and on clinical evaluation of Harris Hip Score in all three groups of evaluated acetabulum defects.
