摘要

The direct anterior approach to the hip has been suggested to have several advantages compared to previously popular approaches through its use of an intra-muscular and intra-nervous interval between the tensor fasciae latae and sartorius muscles.Recent increased interest in tissue-sparing and minimallyinvasive arthroplasty has given rise to a sharp increase in the utilization of direct anterior total hip arthroplasty.A number of variations of the procedure have been described and several authors have published their experiences and feedback to successfully accomplishing this procedure.Additionally,improved understanding of relevant soft tissue constraints and anatomic variants has provided improved margin of safety for patients.The procedure may be performed using speciallydesigned instruments and a fracture table,however many authors have also described equally efficacious performance using a regular table and standard arthroplasty tools.The capacity to utilize fluoroscopy intraoperatively for component positioning is a valuable asset to the approach and can be of particular benefit for surgeons gaining familiarity.Proper management of patient and limb positioning are vital to reducing risk of intra-operative complications.An understanding of its limitations and challenges are also critical to safe employment.This review summarizes the key features of the direct anterior approach for total hip arthroplasty as an aid to improving the understanding of this important and effective method for modern hip replacement surgeons.
