Osteochondral lesions most commonly occur about the knee but may affect any articular surface of the pediatric appendicular skeleton. Osteochondral lesions include osteochondritis dissecans, osteochondral fractures, and osteochondral abnormalities associated with secondary processes such as Legg-Calvé-Perthes disease. These abnormalities should not be confused with normal subchondral irregulari...

Osteopetrosis is a rare inherited disorder of bone causing increased bone density. Legg-Calvé-Perthes disease (LCPD), by contrast, is a more common idiopathic condition leading to variable avascular necrosis of the immature femoral head. We present a case of a 5-year-old boy presenting with these co-morbidities. We have found only one previous reference suggesting these two conditions can coexi...

The aim of treatment of LCPD disease is to prevent cox arthrosis [1]. Several treatment options have been described in order to prevent or limit femoral head deformation by containing the head within the acetabulum. Varisation osteotomy of the femur, salter osteotomy sometimes resulted in a prolonged limb or inadequate containment [2]. Ilizarov distraction technique is [3,4] now well documented...

PURPOSE A new endorectal pull-through technique using a transanal approach is presented in this report. METHODS Mucosectomy, colectomy, and pull-through are performed transanally, and neither laparotomy or laparoscopy are required. Five patients affected with Hirschsprung's disease have been operated on with this technique. CONCLUSION During the 6- to 15-month follow-up period, all of them ...
