This study was designed to provide normal reference values for the centre-edge angle of Wiberg in the Chinese population by measuring 1494 radiographs according to the criteria of Tönnis. The mean angle was 23.1 degrees (4.7 degrees to 46.4 degrees) in childhood (four to nine years), increasing to 28.9 degrees (6 degrees to 48 degrees) in adolescence (10 to(More)
PURPOSE The aim of this study was to test the hypothesis that expression of epidermal growth factor (EGF) and transforming growth factor-beta 1 (TGF-beta 1) may be altered in stenotic tissue of patients with congenital hydronephrosis caused by pelviureteric junction (PUJ) obstruction and to evaluate the role of these 2 growth factors. METHODS The(More)
We retrospectively reviewed 30 hips in 30 patients with complete destruction of the femoral head and neck from infantile septic arthritis to investigate the result and the ideal age for performance of trochanteric arthroplasty. All patients were treated with a 1-stage trochanteric arthroplasty at age from 11 to 98 months. We measured the range of motion of(More)
Eosinophilic granuloma is characterized by single or multiple skeletal lesions occurring predominantly in children, adolescents, and young adults, it accounts for 70% of Langerhans cell histiocytosis. The common sites are the skull, mandible, ribs, spines, and long bones particularly the femur and the humerus. Thoracic rib involvement is rarely seen. It was(More)
A total of 54 cases (73 hips) with ischemic necrosis of the femoral head after treatment of CDH have been followed up with an average of 7 years. We found that 89% cases of type I and 70% of type II recovered to normal and 83% cases of type III and IV developed the coxa breva deformity due to injury of longitudinal growth plate of the proximal end of the(More)
Intramedullary pressure in the proximal femur was measured before and after treatment of congenital dislocation of the hip. The intramedullary pressure before treatment was higher than that of the control group, and after treatment it was lower as a whole; in the close reduction group the pressure decreased as compared with the operation group. In 8 hips,(More)
Multiple epiphyseal dysplasia is a rare congenital osteochondrodysplasia disorder characterized by a delay in the appearance of the epiphyses; irregular, symmetric epiphyseal formation; mild short stature; and early-onset osteoarthritis. Peripheral weight-bearing and nonweight-bearing joints can be affected. Treatment of the hip deformity in multiple(More)
We reported a rare synovial sarcoma arising within sacrum of a 12-year-old boy. A plain radiograph, magnetic resonance imaging performed before surgery, and the intraoperative findings showed that the tumor was S2 and below. Immunohistochemically, desmin and CD34 were negative.
