Total Hip Arthroplasty - Anterolateral Approach

"This technology has decreased the number of blood transfusions in both primary and revision total hip
arthroplasty while also improving the pain severity and function after surgery."

Treating with the AQUAMANTYS® System

Technique as described by Steven H. Weeden, M.D.

Treat Deep Layer Of Subcutaneous Tissue

  • Prior to incising the fascial layer, treat the deep layers of tissue, spot treating to minimize bleeding and oozing.
  • Use only conventional electrocautery to treat the skin and superficial edge bleeders.
  • Minimize general wound bleeding and oozing during procedure.

Pre-emptively Treat Branches of the Superior Gluteal Artery & Vein

  • Use at the apex of the incision to pretreat vessels supplying the bluntly split fibers of the gluteus maximus muscle. These originate from the superior gluteal artery and vein.
  • Reduce bleeding from gluteal vasculature during procedure.

Abductor Prior to Release

  • Pretreat the inferior area of the abductor muscle before it is released.
  • Reduce bleeding from the abductor muscle to improve visibility in the area of the joint capsule.

The Capsule

  • Prior to capsulotomy or capsulectomy, pre-treat the capsule to prevent bleeding and treat any active bleeding by isolating and spot treating the bleeder.
  • Minimize bleeding during and following capsulotomy or capsulectomy.

Femoral Neck Prior to and After Making Cut

  • Treat vessels in the soft tissue anterior and medial to the greater trochanter and those in the region of the femoral neck.
  • The posterior vessels of the neck can be treated after the head is removed and hip is externally rotated to gain exposure to the rest of the neck vessels.
  • Improve visualization prior to, during, and following femoral head removal.

Inferior Transverse Acetabular Ligament & Obturator Artery

  • Treat across the inferior transverse acetabular ligament on both sides of inferior acetabular labrum and into the origin of the obturator vessels which feed into the ligamentum teres. The vessels around the labrum and the acetabulum may also be treated.
  • Improve visualization during reaming and preparation of acetabulum for cup implantation.

Ligamentum Teres & Fovea

  • Treat the inferior acetabular structures leading to the ligamentum teres (round ligament) and the soft tissue of the fovea prior to reaming.
  • Reduce bleeding during and following acetabular cup placement.

Treatment Summary:

  • Deep subcutaneous tissue bleeders
  • Superior gluteal vessels which feed the split of the gluteus maximus muscle
  • Abductor muscle prior to release
  • Hip joint capsule and circumflex arteries
  • Foveal vessels, acetabular labrum, and the vessels feeding the ligamentum teres

To ensure optimal patient benefits, certain areas should not be treated with the AQUAMANTYS® System:

  • Skin & superficial subcutaneous tissue
  • Near neural tissue
  • Bone to be covered by an implant
  • Ligaments and tendons
