“Table-less” and “Assistant-less” Direct Anterior Approach to Hip Arthroplasty

In recent years, specialized, non-sterile, traction table systems have facilitated Direct Anterior Approach (DAA) hip arthroplasty. To combat the potential downsides of these traction systems, a sterile, intra-operative retractor option has emerged as a means to access the surgical site more easily, minimize soft-tissue trauma, and reduce the degree of required human assistance.  This chapter describes the setup, surgical approach, and early results of a retractor system (the Phantom MIS Anterior Hip Retractor system [TeDan Surgical Innovations, Inc. {TSI}, Houston, Texas, US Patent # 8,808,176 B2]), which uses a standard operating table, allows preparation of both lower extremities free in the surgical field, is compatible with fluoroscopy, and aids in both acetabular and femoral exposure, preparation, and implantation. Early outcome data indicates that this system significantly minimizes the need for surgical assistance, while allowing for safe and effective DAA performance, facilitating the procedure for high-volume surgeons and shortening the learning curve for surgeons new to the procedure.
