Bernese periacetabular osteotomy (PAO) developed by Ganz is currently the treatment of choice for skeletally mature symptomatic patients with developmental dysplasia of the hip (DDH) without osteoarthritis. However, the steep learning curve and considerable number of severe complications lead surgeons to seek for alternatives to promote greater reproducibility and safety of this procedure. This is a report of a DDH case surgically treated with the aid of a digital three-dimensional (3D) planning and rapidly prototyped sterile ABS plastic osteotomy guide, developed in Brazil. We present details regarding the planning, guide production, and surgical technique and report the early results of this treatment approach in a single patient. Digital 3D planning and rapidly prototyped surgical guides are applicable and helpful in PAO surgery as shown in this case. We noted no safety issues, good accuracy, and low production costs with this approach.
由甘茨研发的伯尔尼髋臼周围截骨术（PAO）目前是治疗骨骼成熟、有症状且无骨关节炎的发育性髋关节发育不良（DDH）患者的首选方法。然而，陡峭的学习曲线和大量严重并发症促使外科医生寻求替代方法，以提高该手术的可重复性和安全性。本文报告了一例在巴西研发的数字三维（3D）规划和快速成型无菌ABS塑料截骨导向器辅助下手术治疗的DDH病例。我们介绍了规划、导向器制作和手术技术的细节，并报告了该治疗方法在单一患者中的早期结果。如本病例所示，数字3D规划和快速成型手术导向器在PAO手术中是适用且有帮助的。我们注意到这种方法没有安全问题、准确性高且生产成本低。
