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 45o to the coronal plane and 30o to 45o 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 19.4o to 30.2o.
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.
