Background: Developmental Dysplasia of the Hip is a disorder of abnormal development resulting in dysplasia, subluxation, and possible dislocation of the hip secondary to capsular laxity and mechanical instability. The purpose of this study is to assess dynamic antero-posterior hip instability in patients with developmental dysplasia of the hip (DDH) using a lateral radiograph. The purpose of utilizing this procedure is to rule out hip instability and screen for anterior acetabular coverage, both of which are critical for accurate diagnosis and therapy.
Method: The radiographic study was done at the Department of Radio-Diagnosis in a private medical college and hospital in Chennai, Tamil Nadu.A sample of 50 patients was included. The inclusion criteria were patients with hip instability, including prolonged hip pain, and the exclusion criteria were RTA patients, postoperative evaluation, and pregnant women. All the patients in this study underwent an X-ray examination.
Result: Among 50 patients, we measured their W-LCEA and W-ACEA on the AP and FP view radiographs. It clearly shows that over 10 out of 30 individuals with DDH could be missed when only performing an AP pelvic radiograph. Moreover, we found a moderate correlation between the W-LCEA and W-ACEA, suggesting that hips with apparently normal acetabular coverage on the AP view can still exhibit DDH on the FP view.
Conclusion: The study confirms that Lequesne’s false-profile can detect anteroposterior hip instability in DDH patients, potentially aiding diagnosis, treatment evaluation, and cost-effectiveness.
