- Abstract: Purpose: To evaluate the clinical and radiological results of a new innominate osteotomy in Legg-Calve-Perthes' disease (LCPD). Materials and Methods: This study examined 25 hips that were treated with a new innominate osteotomy for LCPD. The treatment involved the anterior half of the ilium being osteomized in a direction of 45degrees to the coronal plane and 30degrees to 45degrees to the sagittal plane, and the posterior half of the ilium being cut using a Gigli saw according to the conventional method. The mean follow-up duration was 5.5 years. Stable interposition of the bone block was achieved using a single biodegradable screw in 8 hips, and without any fixation device in 17 hips. Results: The clinical results according to the criteria of Robinson were good in 20 hips. Twelve hips was graded as good by the Mose method, according to the criteria of Stulberg, 8 hips were included in class I, 6 hips in class II, 8 hips in class III, and 3 hips in class IV. The mean center-edge angle improved from 19.4degrees to 30.2degrees. Conclusion: The new innominate osteotomy is simpler and easier to perform than a routine Salter osteotomy, and satisfactory clinical results can be obtained without fixing the Kirschner wire.
