The deep branch of the medial femoral circumflex artery provides the main relevant blood supply to the femoral head.
Lateral via trochanteric flip
Lateral approach via trochanteric flip is a variant of the surgical hip dislocation approach, which is indicated in children for intracapsular fractures when dislocation is not appropriate.
The transgluteal approach to the proximal femur, between the anterior and medial part of the gluteus medius, provides access to the hip joint at the lateral proximal femur.
This approach is adequate for fracture reduction with K-wire, screw or plate fixation and is indicated in the following situations:
The anterior approach provides the most direct access to the anterior aspect of the hip. Many surgeons prefer this approach for reduction of femoral head and neck fractures.
The lateral approach is indicated in the following situations:
Surgical hip dislocation
Surgical hip dislocation is indicated in children for many conditions of the femoral head and femoral head/neck junction, including fractures.
Surgical hip dislocation provides full visualization of the complete femoral head and acetabulum.
Minimally invasive approach
One great advantage of the ESIN for proximal femoral fractures is that the approach is minimally invasive of the soft tissues, facilitating early joint motion.
