The early findings were band-like hypointense zones on spin-echo images. No operations were performed. Life-table survival curves showed that femoral heads in which the hypointense zone traversed the middle portion of the head were most at risk of subsequent segmental collapse. <\/jats:p>","DOI":"10.1302\/0301-620x.75b2.8444940","type":"journal-article","created":{"date-parts":[[2018,2,21]],"date-time":"2018-02-21T11:55:52Z","timestamp":1519214152000},"page":"217-221","source":"Crossref","is-referenced-by-count":97,"title":["Avascular necrosis of the femoral head.
