Eligibility | Inclusion Criteria: - 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. - Revision of previously failed total hip arthroplasty. The Arcos™ Modular Femoral Revision System hip components are single-use implants, intended for uncemented use only. Only subjects who have received or have already been scheduled to receive hip surgery with the Arcos Revision Stem System will be included in this outcomes study. Additional Inclusion Criteria: - No age limit, however, the patient must have reached full skeletal maturity. - Willing to return for follow up evaluation. Exclusion Criteria: Absolute contraindications include: active infection, sepsis, and osteomyelitis. Relative contraindications include: - Uncooperative patient or patient with neurologic disorders who are incapable of following directions - Osteoporosis - Metabolic disorders which may impair bone formation - Osteomalacia - Distant foci of infections which may spread to the implant site - Rapid joint destruction, marked bone loss or bone resorption apparent on roentgenogram - Vascular insufficiency, muscular atrophy, or neuromuscular disease. |
