The SPECTRON◊ cemented revision system has a proven track record of over fifteen years. The revision femoral stems contain the same features that have made the primary SPECTRON◊ stems clinically successful.
Circulotrapezoidal Neck - provides increased range of motion compared to a circular neck of the same strength.
Anterior/Posterior Grooves - increases rotational stability without increasing cement stresses.
Trapezoidal Stem Cross Section - ideal stem geometry to minimize tensile stresses and aid in compressing the cement under load.
Longitudinal Stem Taper - allows the stresses to be distributed throughout the length of the implant and enhances compressive loading of the cement.
Forged Cobalt Chrome Material - material of choice for cemented stems to reduce stem fractures and minimize generation of third particle debris. The system is comprised of 21 implants in various stem lengths and head/neck offsets.
Long Straight Implant - designed for revision of femoral distal defects such as holes, windows, or fractures around the end of the previously implanted stem.
Neck Replacment Implant - In addition to the indications for the Long Straight implant, the Neck Replacement implant can be used in both primary and revision arthroplasty where bone stock is deficient to the neck area due to femoral neck fracture or failure of a primary stem leading to resorption or destruction of the calcar area.
The instrumentation is designed for a broach-only technique with a minimum number of procedural steps. This makes for a simple, straightforward surgical technique that is highly reproducible.
