Arcos modular revision hip system straight splined tapered distal stem - Press-fit hip femur prosthesis, modular

Intended purpose

Interlok titanium alloy splined tapered distal femoral stem intended for use as one component of the Arcos modular hip revision system. Indications for use: Non-inflammatory degenerative joint disease including osteoarthritis and avascular necrosis; rheumatoid arthritis; correction of functional deformity; treatment of non-union, femoral neck fracture, and trochanteric fractures of the proximal femur with head involvement, unmanageable using other techniques; revision of previously failed total hip arthroplasties. Intended for uncemented use only

Functional description

Non-coated, splined, tapered stem, for use particularly when defect superior to femoral bow. Splined to maximise rotational stability; grit blasted for biologic fixation. 3 deg taper transfers load from proximal to distal femoral portion, reducing stress shielding. 190 mm stem design includes anterior relief to reduce risk of anterior impingement. Diameter 1 mm larger than indicated on packaging to allow for press-fit beyond reamed diameter. Packaged with locking screw. For uncemented use.
