We retrospectively analyzed the charts of 37 patients with chronic, unilateral, moderate, or severe SCFE, who underwent the procedure, verifying Southwick angles, articulotrochanteric distance, and the articular narrowing on preoperative, postoperative periods, and in the last follow-up evaluation, using the contralateral, healthy hip, for comparison. Southwick’s angle changed from 117.8 to 147.3° on average (front) and from 56.9 to 19.1° (Lauenstein view). Articulotrochanteric distance changed from 11.3 to 24.1 mm (normal distance 22.1 mm). Joint space changed from 4.3 mm preoperatively to 3.84 mm. Chondrolysis was diagnosed in five cases before and eight cases after surgery. There was no case of avascular necrosis. Southwick osteotomy effectively corrected SCFE deformity. There was a tendency toward excessive valgism. aSanta Casa de Misericórdia de São Paulo bPediatric Orthopedic Group, Santa Casa de Misericórdia de São Paulo cSchool of Medicine, Santa Casa de Misericórdia de São Paulo, São Paulo, Brazil Correspondence to Cláudio Santili, MD, PhD, Rua Mato Grosso, 306, cj. 1212, Higienópolis, CEP 01239-040 São Paulo (SP), Brazil Tel/fax: +55 11 3237 0085/2114 6090; e-mail: firstname.lastname@example.org © 2013 by Lippincott Williams & Wilkins, Inc.
