Background: Hip dysplasia is a hereditary, dynamic, mechanical condition that can harm the hip's structure. Abnormal hip anatomy leads to abnormal hip mechanical characteristics, which leads to more anatomical defects.
Aim of the work: This study aims to assess the clinical, functional and radiological results of periacetabular Ganz osteotomy in treatment of adolescent acetabular dysplasia.
Patients and methods: This prospective interventional single arm study included 20 patients suffered from acetabular dysplasia and submitted for periacetabular osteotomy at Al-Azhar university hospital in Damietta. The patients were evaluated radiologically and by using the Harris hip score [HHS] before and after operation.
Results: A statistically significant improvement was observed in acetabular index [AI], and Harris Hip Score [HHS] postoperatively [P < 0.001]. Complications were encountered in seven cases [35.0%]. Posterior column fracture occurred in two patients [10.0%], Lateral cutaneous nerve of the thigh dysesthesia was encountered in two patients early after surgery [10.0%], and Superficial wound infection occurred in one patient [5.0%].
Conclusion: The study found Ganz periacetabular osteotomy safe and effective for treating adolescent acetabular dysplasia, resulting in significant improvement in radiographic and functional results.
