Outcome Measures

Primary Outcomes (2)

  • Survival of the study device (liner); whether or not it is still implanted in the subject

    Survivorship will be based on revision or intended revision of the study device (liner).

    At 10 years

  • Adverse Event (safety)

    Safety will be evaluated by monitoring the frequency and incidence of device related adverse events or unanticipated adverse device effects in investigational subjects.

    At 10 years

Secondary Outcomes (4)

  • Pain and Function using Modified Harris Hip Score

    At 10 years

  • Pain and Function using Oxford Hip Score

    At 10 years

  • Patient Quality of Life using EQ-5D-5L Descriptive System

    At 10 years

  • Patient Quality of Life using EQ-5D-5L EQ visual analogue scale

    At 10 years

Study Arms (1)

G7 Shell with Vivacit-E and Longevity Highly Crosslinked Polyethylene Liners

OTHER

Up to 300 hips globally will be implanted with a G7 Shell and either the Vivacit-E or Longevity Liner. The liner used by each site will be identified at start-up.

Device: Vivacit-E and Longevity (HXLPE) Liners

Interventions

This is a dual cohort study in which 150 subjects will receive the Vivacit-E (HXLPE) Liner and 150 subjects will receive the Longevity (HXLPE) Liner.

  • Patient must be treated for one of the following indications:
  • Noninflammatory degenerative joint disease including osteoarthritis and avascular necrosis
  • Rheumatoid arthritis
  • Correction of functional deformity
  • Treatment of non-union, femoral neck fracture, and trochanteric fractures of the proximal femur with head involvement, unmanageable by other techniques
  • Revision procedures where other treatment or devices have failed
  • Patient must be able and willing to complete the protocol required follow-up visits.
  • Patient must be able and willing to sign the Institutional Review Board or Ethics Committee (IRB/EC) approved informed consent.

  • Patient has a metabolic disorder that may impair bone formation.
  • Patient has osteomalacia.
  • Patient has distant foci of infections which may spread to the implant site or patient with infection, sepsis or osteomyelitis.
  • Patient has rapid joint destruction, marked bone loss or bone resorption apparent on roentgenogram.
  • Patient has a vascular insufficiency, muscular atrophy, or neuromuscular disease
  • Patient is a prisoner.
  • Patient is a current alcohol or drug abuser.
  • Uncooperative patient or patient with neurologic disorders who is incapable or unwilling to follow directions.
