Preoperative and follow-up (at 2\u20133, 4\u20136, 7\u20139 and 10\u201315 years of age) Sharp's acetabular angles (AA) and the final Wiberg's center-edge angles (CEA) and proximal femoral center-trochanter distances (CTD) of 13 hips with group I AVN (AVN group) were compared with measurements of 22 hips without AVN (control group). All hips were initially treated by the same soft tissue surgical procedure (posteromedial limited surgery) under the age of 18 months and were completely followed up to at least 10 years of age. Radiographic diagnosis of group I AVN was made between 6 and 12 months postoperatively. The period for complete radiographic recovery of group I ischemic changes was between 2 to 4.5 years. Preoperative mean AA values of both groups were similar. However, the mean AA was found to be worse in the AVN group than in the control group during follow-up. Control group hips had a better mean CEA and higher number of hips having normal CTD than the AVN group, at latest follow-up. In conclusion, when compared with uncomplicated hips, group I ischemic changes retard acetabular development and have quantitative unfavorable effects on lateral femoral head coverage and proximal femoral anatomy in DDH. In addition, the healing process in group I AVN patients is extended.<\/jats:p>","DOI":"10.1177\/112070001002000205","type":"journal-article","created":{"date-parts":[[2018,1,24]],"date-time":"2018-01-24T11:20:31Z","timestamp":1516792831000},"page":"156-162","source":"Crossref","is-referenced-by-count":5,"title":["Is Kalamchi and MacEwen Group I avascular necrosis of the femoral head harmless in developmental dysplasia of the hip?"],"prefix":"10.1177","volume":"20","author":[{"given":"Haluk","family":"A\u011fu\u015f","sequence":"first","affiliation":[{"name":"2nd Orthopaedics and Traumatology Clinic, Tepecik Teaching and Research Hospital, Izmir - Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hakan","family":"\u00d6mero\u011flu","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics and Traumatology, Eski\u015fehir Osmangazi University Faculty of Medicine, Eski\u015fehir - Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ali","family":"Bi\u00e7imo\u011flu","sequence":"additional","affiliation":[{"name":"3rd Orthopaedics and Traumatology Clinic, Ankara Numune Teaching and Research Hospital, Ankara - Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Y\u00fccel","family":"T\u00fcmer","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics and Traumatology, Kent Hospital, Izmir - Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2018,1,24]]},"reference":[{"issue":"1","key":"bibr1-112070001002000205","first-page":"54","volume":"41","author":"Connolly P.","year":"2007","journal-title":"Acta Orthop Traumatol Turc"},{"key":"bibr2-112070001002000205","first-page":"27","volume":"28","author":"Fernandez C.A.","year":"2008","journal-title":"Iowa Orthop J"},{"key":"bibr3-112070001002000205","unstructured":"HerringJ.A.
