We used the T-saw and its modified version with diamond-particle coating as new cutting devices for the pelvic osteotomy. Eight hips were included in this case series. The osteotomy was performed in patients at an average age of 5.3 years. The average operation time was 93 minutes. The average blood loss during surgery was 102 g. The average follow-up period was 34 months. The average center-edge angle improved from −2.5° preoperatively to 17.5°. Sharp angle also decreased from 54.4° to 45.3°. We did not experience any complications. Because the cut of the T-saw is very sharp, it can cut at smaller angles than the conventional Gigli saw. This is very valuable for surgery in children who require smaller exposure of the surgical site. We recommend the T-saw and Diamond T-saw for Salter innominate osteotomy. © 2011 Lippincott Williams & Wilkins, Inc.
