To achieve better communication among physicians,better treatment planning and evaluation of the results of various treatment options,an agreed terminology is needed to describe the entire pathology. Furthermore,a generally accepted classification of the deformities is necessary. Herein,the authors propose the use of the term "congenital hip disease" and its classification as dysplasia,low dislocation and high dislocation. Knowledge of the CHD natural history facilitates comprehension of the potential development and progression of the disease,which differs among the aforementioned types. This can lead to better understanding of the anatomical abnormalities found in the different CHD types and thus facilitate preoperative planning and choice of the most appropriate management for adult patients. The basic principles for improved results of total hip replacement in patients with CHD,especially those with low and high dislocation,are: Wide exposure,restoration of the normal centre of rotation and the use of special techniques and implants for the reconstruction of the acetabulum and femur. Application of these principles during total hip replacement in young female patients born with severe deformities of the hip joint has led to radical improvement of their quality of life.展开更多

Autograft concern is further supported by authors who suggest the routine use of internal fixation. Problems such as graft extrusion, rotation and absorption, leading to loss of acetabular correction, were often noted in cases previously treated at our National Hospital for Pediatrics. This retrospective study reviewed the radiographic results of this treatment protocol in 106 hips developmental dislocated hips which met our inclusion criteria. The efficacy of this method to achieve and maintain a well covered and stable hip was the main objective of the study. Methods: This retrospective study reviewed the radiographs of 106 hips presenting with developmental dislocation which were treated by modified Salter’s innomiate osteotomy and using a fibular allograft as the interposition material. Dislocations of the hip were graded using the T?nnis system. Measurement of the acetabular index (AI) was the main variable. The minimum follow up period was 2 years. Possible complications such as loss of acetabular correction, hip redislocation, graft extrusion or resorption, the need for osteotomy internal fixation, delayed or non union, infection or avascular necrosis (AVN) were documented in this series. Results: Between January 2004 and December 2008, 106 surgeries were performed in 95 patients. Sixty-three (86.3%) of the patients were girls and ten (13.7%) were boys, thirteen patients (13.7%) were between twelve and eighteen months old at the time of the operation, the remaining eighty-two (86.3%) patients being between eighteen and thirty-six months old, with the mean age of 22.6 months at the time of surgery. There were eleven (11.6%) patients who had bilateral dislocation. Eighty-four (88.4%) patients were affected unilaterally.
