Cleared indications for the RingLoc Bipolar and Endo II Heads include the following:
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 using other techniques.

Exclusion

Any medical diagnosis present at the time of surgery that, at the Investigator's discretion, could compromise the implant's survivability

What this trial measures

  • Device safety assessed through the frequency and incidence of revisions, complications, and Adverse Events.Greater than or equal to 8 years.

    The primary objective of this study is the assessment of safety by analyzing implant survivorship. This will be established by recording the incidence and frequency of revisions, complications, and Adverse Events. Relation of the events to either implant or instrumentation will be specified.
