ABSTRACT
The modified posterior approach (PA) shows that forces required to dislocate the hip and disrupt the reattachment of the lateral rotators were considerably more using this new approach than with the Southern approach, thereby confirming the greater posterior stability of the recommended modification. The PA is the most commonly used surgical approach for total hip arthroplasty worldwide. There have been several iterations of the PA since it was first described by von Langenbeck in 1874, where he mentioned that in all 11 PAs have been described when all either divide the short external rotators or pass between them. Numerous surgical approaches to the hip joint have been described over the years. Each approach offers certain advantages and has its own unique limitations. Access is the key to success; it is essential for the surgeons to be aware of the different surgical approaches in order to deal with variable complex clinical situations.
