Two independent observers assessed the radiographs for the presence of RLLs.<h4>Results</h4>The overall prevalence of RLLs in zone 7 was 13% (83/636). Patients with RLLs in zone 7 had an average OHS of 40.3 (15-48), and those who did not have RLLs in zone 7 had an average OHS of 38 (6-48), <i>P</i> = .07. Both groups had an average pain score of 1.6 out of 5, <i>P</i> = .5. The prevalence of RLLs in zone 7 was much less in the collared femoral components (2.6% prevalence) than in the collarless components (23.6% prevalence), but there was heterogeneity between these 2 groups preventing comparison. Logistic regression analysis of only the collarless components identified undersizing as the only predictive (odds ratio = 2.6) factor for RLL development in zone 7.<h4>Conclusions</h4>Undersizing the Corail stem is strongly predictive of developing RLLs in zone 7. Preoperative templating for the appropriate size is critical. We observed more RLLs in zone 7 with the collarless design Corail, but a comparison study with the same bearing couple is needed to investigate this further."],"journal":["Arthroplasty today"],"pagination":["99-103"],"full_dataset_link":["https://www.ebi.ac.uk/biostudies/studies/S-EPMC7083744"],"repository":["biostudies-literature"],"pubmed_title":["Observed effect of femoral component undersizing and a collarless design in the development of radiolucent lines in cementless total hip arthroplasty."],"pmcid":["PMC7083744"],"pubmed_authors":["Magill P","Beverland D","Machenaud A","O'Brien S","Hill J","Stevenson M"],"additional_accession":[]},"is_claimable":false,"name":"Observed effect of femoral component undersizing and a collarless design in the development of radiolucent lines in cementless total hip arthroplasty.","description":"<h4>Background</h4>The objective of this study was to determine the prevalence of radiolucent lines (RLLs) around the femoral component in a cohort of patients who underwent well-functioning cementless total hip arthroplasty (THA).<h4>Methods</h4>A cohort of unrevised Corail (DePuy Synthes, Raynham, MA) femoral components (n = 636) were analyzed at a median follow-up of 6.0 years (interquartile range: 5.2-6.8) with the Oxford Hip Score (OHS) and radiographs.
