Intended Use

Total hip components are indicated for uncemented use only in individuals undergoing primary and revision surgery where other treatments or devices have failed in rehabilitating hips damaged as a result of trauma, inflammatory joint disease such as rheumatoid arthritis, or noninflammatory degenerative joint disease (NIDJ) or any of its composite diagnoses such as osteoarthritis; avascular necrosis; traumatic arthritis; slipped capital epiphysis; fused hip; fracture of the pelvis; diastrophic variant; old, remote osteomyclitis with an extended drainage-free period; nonunion, femoral neck fracture and trochanteric fractures of the proximal femur with head involvement that are unmanageable using other techniques; fernoral osteotomy, or Girdlestonc resection; fracture dislocation of the hip; and correction of deformity. The Synergy Porous Size 8 Hip Stem is designed for single use only.

Device Story

Synergy Porous Size 8 Hip Stem is a metallic femoral component for total hip arthroplasty. Device is implanted by orthopedic surgeons in clinical settings to replace damaged hip joints. It functions as a structural prosthesis, designed for uncemented fixation. It is compatible with modular cobalt chrome or ceramic femoral heads via a 12/14 taper. The device provides mechanical stability and restores joint function for patients with degenerative or traumatic hip conditions. It is intended for single use only.

Clinical Evidence

No clinical data provided; substantial equivalence is based on technological characteristics and design similarities to legally marketed predicate devices.

Technological Characteristics

Material: Titanium alloy (Ti-6Al-4V, ASTM F1472). Design: Porous tapered hip stem. Compatibility: Modular cobalt chrome or ceramic femoral heads with 12/14 taper. Fixation: Uncemented. Single-use only.

Indications for Use

Indicated for individuals undergoing primary and revision hip surgery for trauma, inflammatory joint disease (e.g., rheumatoid arthritis), noninflammatory degenerative joint disease (e.g., osteoarthritis), avascular necrosis, traumatic arthritis, slipped capital epiphysis, fused hip, pelvic fracture, diastrophic variant, remote osteomyelitis, nonunion, femoral neck/trochanteric fractures, femoral osteotomy, Girdlestone resection, fracture dislocation, 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.
