Advantages and Disadvantages for Anterior Approach Versus Trochanteric Flip Osteotomy

Advantages	Disadvantage
•Intermuscular plane, with minimal damage to the muscles. •Avoidance of the MFCA, the major blood supply to the femoral head and neck. •Avoidance of a trochanteric osteotomy with possible non- or malunion of osteotomy. •Avoidance of hardware for osteotomy fixation or need for hardware removal.	•Encountering scar tissue in cases of previous surgery via anterior approach or prior arthroscopy. •Limited access to posteroinferior quadrant of femoral head. •Limited access to acetabulum and labrum.
