Surgical management of paralytic hip dislocation

Background and aim The goal of surgical treatment for paralytic hip dislocation is to properly position the femoral head in its natural place while relieving pain. This study aimed to assess the outcomes of surgical treatment for paralytic hip dislocation among patients with various causes of hip paralysis and to compare the results of fixation of proximal femoral varization osteotomy with derotation either by conventional or a new double-angled blade plate 90 plate 90°. Patients and methods A prospective study in which 50 children with paralytic hip dislocation were divided into two groups: 25 cases for each. Patients were treated by open reduction, proximal femoral varization osteotomy, where the first group was fixed by a conventional double-angled blade plate (90°), and the second group was fixed by a new double-angled blade plate (90°). Preoperative radiographs and specific imaging markers (acetabular index, migration percentage, and neck shaft angle) were measured. Results The age of the children ranged from 5 to 15 years. The new double-angled blade plate (90°) technique showed a lower complication rate, reduced operative time, and blood loss. Also, the radiological indices showed significant improvement between preoperative levels and immediate postoperative, 6 weeks, 3 months, 6 months, and 1-year postoperative levels. Conclusion Surgery for paralytic hip dislocation, especially the new double-angled blade plate (90°) technique, can improve a patient’s quality of life, having a lower complication rate, reduced operative time and blood loss, and improved radiological indices, making it an efficient and effective choice for managing complex cases.
