Intended Use

The GLADIATOR™ Bipolar System is indicated for the following conditions: 1) pathological fractures of the femoral neck 2) non-union of femoral neck fractures 3) aseptic necrosis of the femoral head and neck 4) primary pathology in the young involving the femoral head but with a non-deformed acetabulum.

Device Story

GLADIATOR™ Bipolar System is a hemi-hip prosthesis; used for femoral head replacement. System consists of cast CoCr alloy shells (36-65mm O.D.) and cross-linked UHMWPE bearing inserts (22-36mm I.D.) with UHMWPE locking/support rings. Components are permanently assembled during production. Device is implanted by orthopedic surgeons to restore hip joint function in patients with specific femoral head pathologies. It functions as a mechanical replacement for the femoral head, articulating within the patient's natural acetabulum.

Clinical Evidence

No clinical data provided; bench testing only.

Technological Characteristics

Materials: Cast CoCr alloy (shells), cross-linked UHMWPE (bearing inserts, locking/support rings). Form factor: Bipolar hip prosthesis, shell O.D. 36-65mm, I.D. 22-36mm. Components are permanently factory-assembled. Mechanical device; no software or energy source.

Indications for Use

Indicated for patients with pathological femoral neck fractures, non-union of femoral neck fractures, aseptic necrosis of the femoral head/neck, or primary femoral head pathology with non-deformed acetabulum.

Regulatory Classification

Identification

A hip joint femoral (hemi-hip) metal/polymer cemented or uncemented prosthesis is a two-part device intended to be implanted to replace the head and neck of the femur. This generic type of device includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum, and a snap-fit acetabular component made of an alloy, such as cobalt-chromium-molybdenum, and ultra-high molecular weight polyethylene. This generic type of device may be fixed to the bone with bone cement (§ 888.3027) or implanted by impaction.

Dear Mr. Paul:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA), You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice; labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898.
