Skin incision

Longitudinal incsion with one-half being over the trochanter and one-half below it

Subcutaneous dissection

exposure of the iliotibial band and tensor fascia-latae muscle.

The posterior border of the gluteus medius is retracted using a 90° angled thin Homan retractor.

The external rotators muscle group are identified.

The external rotators muscle group are tagged by sutures and incised

The capsule incised along the longitudinal posterior border of the trochanter

Hip is dislocated posteriorly

Mid-neck resection level

The angle of the resection is parallel to the line connecting the greater and lesser trochanters.

The curved starter awl is used to initiate femoral preparation

Femoral canal preparation

the direction of the broach in the medullary canal following the curvature of the neck

Exposure of the acetabulum

retractors are placed at anterior, posterior and superior borders of the acetabulum

Acetabular reaming

Acetabular trial

Stem trial

the trail neck and head are attached to the broach

Reduction trial

Trial reduction performed using the appropriate sized trial head

Implantation of the stem

The implant inserted first by hand and then subsequently impacted with the impactor into the femoral canal with the stem impactor

Final position

The head is reduced into definitive cup.
