Intended Use
The components are indicated for cemented and uncemented use for individuals undergoing primary and revision surgery where other treatments or devices have failed for rehabilitating hips damaged as a result of trauma, or noninflammatory degenerative joint disease (NIDJD) or any of its composite diagnoses of osteoarthritis, avascular necrosis, traumatic arthritis, slipped capital epiphysis, fused hip, fracture of the pelvis, and diastrophic variant. Indications also include inflammatory degenerative joint disease including rheumatoid arthritis, arthritis secondary to a variety of diseases and anomalies, and congenital dysplasia; old, remote osteomyelitis with an extended drainage-free period; treatments of nonunion, femoral neck fracture and trochanteric fractures of the proximal femur with heads involvement that are unmanageable using other techniques; endoprosthesis, femoral osteotomy, or Girdlestone resection; fracture-dislocation of the hip; and correction of deformity.
Device Story
Global Taper (GT) Tapered Hip System comprises metal alloy hip stems and femoral heads; designed for primary or revision hip arthroplasty. Used in clinical/OR settings by orthopedic surgeons. Provides structural replacement for damaged hip joints; supports both cemented and uncemented fixation. Enables rehabilitation of hip function following trauma or degenerative disease. Single-use device.
Clinical Evidence
Bench testing only; no clinical data provided.
Technological Characteristics
Metal alloy hip stems and femoral heads; tapered design; supports cemented or uncemented fixation; single-use.
Indications for Use
Indicated for patients undergoing primary or revision hip surgery due to trauma, NIDJD (osteoarthritis, avascular necrosis, traumatic arthritis, slipped capital epiphysis, fused hip, pelvic fracture, diastrophic variant), inflammatory degenerative joint disease (rheumatoid arthritis, congenital dysplasia), remote osteomyelitis, nonunion, femoral neck/trochanteric fractures, or deformity correction.
Regulatory Classification
Identification
A hip joint metal/polymer/metal semi-constrained porous-coated uncemented prosthesis is a device intended to be implanted to replace a hip joint. The device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across the joint. This generic type of device has a femoral component made of a cobalt-chromium-molybdenum (Co-Cr-Mo) alloy or a titanium-aluminum-vanadium (Ti-6Al-4V) alloy and an acetabular component composed of an ultra-high molecular weight polyethylene articulating bearing surface fixed in a metal shell made of Co-Cr-Mo or Ti-6Al-4V. The femoral stem and acetabular shell have a porous coating made of, in the case of Co-Cr-Mo substrates, beads of the same alloy, and in the case of Ti-6Al-4V substrates, fibers of commercially pure titanium or Ti-6Al-4V alloy. The porous coating has a volume porosity between 30 and 70 percent, an average pore size between 100 and 1,000 microns, interconnecting porosity, and a porous coating thickness between 500 and 1,500 microns. The generic type of device has a design to achieve biological fixation to bone without the use of bone cement.
