Ischio-Pubic-Patella Syndrome

Abstract

It has been stated that regulation of the development of the iliac bone is different from that of the ischium and pubis. There are well-known clinical syndromes concerned with hypoplasia of ischiopubic bone, such as small patella syndrome, nail-patella syndrome, ischiopubic-patellar hypoplasia, and ischiopubic hypoplasia. A 3 year male child presented with right knee pain since 2 weeks. She sought advice from an orthopedic surgeon and was advised for x-ray right knee. On reviewing the X-ray patella were absent and then further X-rays of left knee , pelvis , spine, elbow and foot were taken on suspicion of ischio pubic patellar dysplasia (IPD) or small patella syndrome. Patient had absent patella on left side and bilateral defective ischio pubic ossification with no spinal, elbow or foot abnormalities.Bilateral inferior ischiopubic hypoplasia along with bilateral patellar aplasia with no spinal, elbow or foot abnormalities probably constitutes a new syndrome. To the best of the author's knowledge, this finding has not been described previously [Marekar A NJIRM 2015; 6(2):115-116]
