The average follow-up period was 49 months (range: 24\u201377 months). The lateral bone coverage of the cups was assessed by determining the cup center-edge (cup-CE) angle and the bone coverage index (BCI) from anteroposterior pelvic radiographs. Further, cup fixation was determined using the modified DeLee and Charnley classification system.<jats:italic>Results.<\/jats:italic>All cups were judged to show stable fixation by bone ingrowth. The cup-CE angle was less than 0\u00b0 in 7 hips (3.3%) and the minimum cup-CE angle was \u22129.2\u00b0 (BCI: 48.8%). Thin radiolucent lines were observed in 5 hips (2.3%), which were not associated with decreased lateral bone coverage. Loosening, osteolysis, dislocation, or revision was not observed in any of the cases during the follow-up period.<jats:italic>Conclusion.<\/jats:italic>A cup-CE angle greater than \u221210\u00b0 (BCI &gt; 50%) was acceptable for stable bony fixation of the cup. Considering possible errors in manual implantation, we recommend that the cup position be planned such that the cup-CE angle is greater than 0\u00b0 (BCI &gt; 60%).<\/jats:p>","DOI":"10.1155\/2017\/4937151","type":"journal-article","created":{"date-parts":[[2017,2,19]],"date-time":"2017-02-19T16:02:35Z","timestamp":1487520155000},"page":"1-7","source":"Crossref","is-referenced-by-count":27,"title":["Minimum
