Surgical Technique: Endoscopic Shelf Acetabuloplasty

Patients with hip dysplasia have a greater risk of acetabular labral tearing and joint instability, disposing them to osteoarthritis. Except for borderline hip dysplasia, hip arthroscopic labral preservation is not generally an accepted tool for the treatment of hip dysplasia. An open surgical approach such as periacetabular osteotomy is commonly used for hip dysplasia.Hence, we devised a new strategy, which concurrently addresses labral, capsular, and bony pathology in an arthroscopic manner. The purpose of this book chapter is to demonstrate surgical technique of endoscopic shelf acetabuloplasty for treating patients in the setting of hip dysplasia. The proposed surgical technique is technically demanding, but surgical devices have been rapidly evolving. This resurrection of the classic shelf procedure is a feasible less invasive option to actebular reorientation surgeries and outcomes may be improved because of the concurrent arthroscopic treatment of CAM femoroacetabular impingement and chondrolabral pathology.
