Intended Use
This device is intended to be used for: 1. noninflammatory degenerative joint disease including osteoarthritis and avascular necrosis, 2. rheumatoid arthritis, 3. correction of functional deformity, 4. revision procedures where other treatments or devices have failed, 5. treatment of non-unions, femoral neck and trochanteric fractures of the proximal femur with head involvement, unmanageable using other techniques, 6. treatment/reduce pain, 7. treatment of osteomyelitis, 8. endoprosthesis femoral osteotomy, 9. use determined by the physician using sound medical judgment.
Device Story
Zirconia ceramic femoral head; spherical design with 12/14 taper trunnion bore; articulates with polyethylene acetabular component. Used in hip arthroplasty procedures; implanted by orthopedic surgeons. Provides load-bearing surface for hip joint replacement; restores joint function; reduces pain in patients with degenerative or traumatic hip conditions.
Clinical Evidence
No clinical data provided; bench testing only.
Technological Characteristics
Magnesia stabilized zirconia ceramic; 12/14 taper trunnion bore; spherical geometry; sterilized via 100% ethylene oxide in nitrogen per AAMI guidelines.
Indications for Use
Indicated for patients requiring hip arthroplasty due to noninflammatory degenerative joint disease (osteoarthritis, avascular necrosis), rheumatoid arthritis, functional deformity, revision surgery, non-unions, or proximal femoral fractures with head involvement.
Regulatory Classification
Identification
A hip joint metal/ceramic/polymer semi-constrained cemented or nonporous uncemented prosthesis is a device intended to be implanted to replace a hip joint. This device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. The two-part femoral component consists of a femoral stem made of alloys to be fixed in the intramedullary canal of the femur by impaction with or without use of bone cement. The proximal end of the femoral stem is tapered with a surface that ensures positive locking with the spherical ceramic (aluminium oxide, A12 03 ) head of the femoral component. The acetabular component is made of ultra-high molecular weight polyethylene or ultra-high molecular weight polyethylene reinforced with nonporous metal alloys, and used with or without bone cement.
