Spectron Revision Long Straight Femoral Component - Uncoated hip femur prosthesis; modular

Intended purpose

A sterile femoral component of a total hip system. The stem was designed for revision of femoral distal defects such as holes, windows, or fractures around the end of the previously implanted stem. Hip components are indicated for individuals undergoing primary and revision surgery where other treatments or devices have failed in rehabilitating hips damaged as a result of degenerative joint disease or any of its composite diagnoses of osteoarthritis, avascular necrosis, and traumatic arthritis. Hip components are also indicated for inflammatory degenerative joint disease including rheumatoid arthritis, congenital dysplasia, femoral neck fracture, and trochanteric fractures of the proximal femur with head involvement that are unmanageable using other techniques, and fracture-dislocation of the hip.

Functional description

A cemented Cobalt Chrome femoral stem with a 12/14 taper, circulotrapezoidal neck, and longitudinal stem taper. The femoral canal is rasped with sequential broaches. After trialing and femoral canal preparation, a Buck cement restrictor is inserted into the canal and cement is injected from a pressurized gun. A stem driver is used to drive the stem into the femoral canal. Excess cement should be removed prior to femoral head impaction on the neck taper.
