About

The main objectives of this study are to confirm the long-term safety, performance, and clinical benefits of the G7 Acetabular Shells when used with the Vivacit-E and Longevity HXLPE liners and instrumentation in primary and revision total hip arthroplasty.

Full description

The primary endpoint is defined by the survival of the implant system at 10 years, which is based on removal or intended removal of the study device and will be determined using Kaplan Meier method. The safety of the system will be assessed by monitoring the frequency and incidence of adverse events. Relation of the events to either implant or instrumentation should be specified.

The secondary endpoints are the assessment of performance and clinical benefits by recording patient-reported clinical outcomes measures (PROMs) as well as radiographic outcomes (if available).

Inclusion criteria

  • Patient must be a legal adult who has reached full skeletal maturity.
  • 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.

Exclusion criteria

  • 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.
