Periacetabular Ganz Osteotomy in the Treatment of Adolescent Acetabular Dysplasia

Background: Hip dysplasia is a hereditary, dynamic, mechanical condition that can harm the hip&#039;s structure. Abnormal hip anatomy leads to abnormal hip mechanical characteristics, which leads to more anatomical defects. Aim: 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 opartsion. 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%). Posterior column fracture occurred in two patients (10%), Lateral cutaneous nerve of the thigh dysesthesia was encountered in two patients early after surgery (10%), and Superficial wound infection occurred in one patient (5%). Conclusion: The study found Ganz periacetabular osteotomy safe and effective for treating adolescent acetabular dysplasia, resulting in significant improvement in radiographic and functional result
