The SMF system is a total hip system consisting of proximally porous coated titanium alloy (Ti-6Al-4V) tapered femoral hip stems with optimized and easy to use instrumentation. It offers the surgeon an improved bone conserving implant that is compatible with high demand femoral head bearing options from Smith & Nephew. The SMF hip stem is shorter than conventional hip stems, which allows the stem to conserve more of the patient’s femur than other prostheses. The SMF hip stem requires a slightly higher neck resection.
The proximal porous coating of the stem consists of STIKTITE™ coating, a commercially pure Titanium coating, and is designed to have a press-fit relative to the broach of approximately 1/4mm. The stems are proportionally sized and shaped in sizes -1 through 6 (core sizes), with optional
larger sizes 7 through 9 (extended sizes).
The SMF stem components are indicated for uncemented use 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 (NIDJD) or any of its composite diagnoses such as
osteoarthritis; avascular necrosis; traumatic arthritis; slipped capital epiphysis; fused hip; fracture of the pelvis; diastrophic variant; nonunion, femoral neck fracture and trochanteric
fractures of the proximal femur with head involvement that are unmanageable using other techniques; femoral osteotomy, or Girdlestone resection; fracture dislocation of the hip; and
correction of deformity.
