Safe Arthroscopic Access to the Central Compartment of the Hip

Abstract 

This technical note describes a new method that allows access to the central compartment of the hip under arthroscopic control via the peripheral compartment with less risk of labral perforation and/or cartilage scuffing. After placement of the anterolateral portal in the peripheral compartment without traction, the anterior head area with the anterior acetabular labrum and the anterior surface of the femoral head are inspected. Under arthroscopic control, a guidewire is introduced through the anterior portal in between the anterior labrum and anterior femoral head cartilage and into the central compartment. The arthroscope is then removed from the anterolateral portal, the hip distracted, and the arthroscope introduced via cannulated instruments over the guidewire into the central compartment. Further portal placement can be controlled arthroscopically.
