REFLECTION

Acetabular Cup System

Product Information

REFLECTION Product Information

The REFLECTION Acetabular Cup System has led the industry in maximising fixation and minimising wear since 1992, offering 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 virtually eliminates damage to the backside of the liner reducing the chance of backside wear.

Features and Benefits of REFLECTION by Smith & Nephew

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

Clinical Evidence

Comparative in vitro assessment of the primary stability of cementless press-fit acetabular cups

Acta Orthop. Belg., 2004, 70, 31-37.

Long-term stable osseointegration of porous-coated acetabular cups depends on bony ingrowth within their porous surface.

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 minimizes 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 reduces roughness to the standard required for femoral heads, further reducing backside wear

RoughCoat Porous Coating
• Sintered Ti Bead technology has been the gold standard in hip replacement for the last 10 years.
• 40% average porosity

Indications


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.
