The material included 23 shelf acetabuloplasty procedures for LCP disease. The average age at diagnosis was 8.1 years (range 4\u201312). Mean follow-up was 5.8 years (range from 2.2 to 11.2 years). Mean Reimer's index decreased statistically significantly from a mean of 32% before surgery to 10.0% at the last follow-up (<mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M1\"><mml:mi>P<\/mml:mi><mml:mo>&lt;<\/mml:mo><mml:mn>0<\/mml:mn><mml:mo>.<\/mml:mo><mml:mn>00001<\/mml:mn><\/mml:math>). The mean Wiberg center-edge angle increased also statistically significantly from a mean of 17.3\u00b0 before procedure to 32.3\u00b0 at the last follow-up (<mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M2\"><mml:mi>P<\/mml:mi><mml:mo>&lt;<\/mml:mo><mml:mn>0<\/mml:mn><mml:mo>.<\/mml:mo><mml:mn>00001<\/mml:mn><\/mml:math>). According to the Stulberg classification, type I was observed in 2, type II in 13, type III in 6, and type IV in 2 hips. There were no differences in the range of motion or leg length discrepancy in preoperative and postoperative standing. Partial, not significant, bone graft resorption was noted in 6 cases in the first 6\u20139 months after surgery. To conclude, shelf acetabuloplasty allows achieving good midterm results in the treatment of severe stages of LCP disease. The procedure improves coverage of femoral head and allows its remodelling.<\/jats:p>","DOI":"10.1155\/2013\/859483","type":"journal-article","created":{"date-parts":[[2013,11,27]],"date-time":"2013-11-27T23:02:52Z","timestamp":1385593372000},"page":"1-5","source":"Crossref","is-referenced-by-count":11,"title":["Shelf Acetabuloplasty in the Treatment of Severe Legg-Calv\u00e9-Perthes Disease: Good Outcomes at Midterm Follow-Up"],"prefix":"10.1155","volume":"2013","author":[{"given":"Andrzej","family":"Grzegorzewski","sequence":"first","affiliation":[{"name":"Clinic of Orthopaedics and Paediatric Orthopaedic, Medical University of \u0141\u00f3d\u017a, ul.
