Acetabular Cup System

REFLECTION Acetabular cups

Product Information

REFLECTION Product Information

The REFLECTION Acetabular Cup System offers a variety of choices, allowing the surgeon versatility for indication and preference. The MICROSTABLE liner locking mechanism and the patented polished inner surface reflect our continued leadership in advanced technology. The combination of our locking mechanism and polished surface is intended to minimize damage to the backside of the liner reducing the chance of backside wear.

Features and Benefits

  • MICROSTABLE liner locking mechanism
  • Highly Polished Inner Surface
  • ROUGHCOAT Porous Coating
  • NO HOLE and THREE HOLE options for primary
  • MULTI HOLE for Revision surgeries
  • Taper lock screw hole covers, watertight apex hole cover
  • ROUGHCOAT sintered bead porous coating allows for scratch fit and intended to allow for bone in-growth.

Fixation of Ultrahigh-molecular-weight Polyethylene Liners to Metal-backed Acetabular Cups

The Journal of Arthroplasty Vol. 12 No. 1 1997.

Locking mechanisms and metal-liner interface surfaces of six modular acetabular systems were evaluated to determine their effect on micromotion and backside wear of the polyethylene liner.

Design and Technology

REFLECTION Design and Technology

MICROSTABLE liner locking mechanism

  • Smooth scalloped design of locking mechanism is intended to minimize damage to poly from locking into shell
  • 24 positions allows you the interoperative flexibility to reposition
  • The non-damaging lock mechanism allow repeated removal and reinsertion of the liner

Highly Polished Inner Surface


  • Patented Polished inner surface helps to reduce roughness to the for femoral heads, intended to reduce backside wear

ROUGHCOAT Porous Coating

  • 40% average porosity



REFLECTION Indications

Hip components are indicated for individuals undergoing primary and revision surgery where other treatments or devices have failed in rehabilitating hips damaged as a result of trauma or noninflammatory degenerative joint disease (NIDJD) or any of its composite diagnoses of:

  • Osteoarthritis
  • Avascular necrosis
  • Traumatic arthritis
  • Slipped capital epiphysis
  • Fused hip
  • Fracture of the pelvis and diastrophic variant.

Hip components are also indicated for inflammatory degenerative joint disease including:

  • Rheumatoid arthritis
  • Arthritis secondary to a variety of diseases and anomalies, and congenital dysplasia;
  • Treatments of nonunion
  • Femoral neck fracture
  • Trochanteric fractures of the proximal femur with head involvement that are unmanageable using other techniques
  • Endoprosthesis, femoral osteotomy
  • Girdlestone resection
  • Fracture-dislocation of the hip
  • Correction of deformity.
