Tri-Taper™ Design for increased stability and reduced trauma in less invasive hip approaches Less invasive approaches to total hip surgery can be advantageous to patients due to the reduction in soft tissue trauma and the potential for earlier recovery. However, these techniques necessarily result in a surgical window with restrictive geometry which can complicate insertion and placement of traditional length femoral components. DJO Surgical designed the TaperFill® femoral stem with a shortened overall length and an anatomically congruent, Tri-Taper profile to ease insertion, prevent subsidence and achieve stability. Data Driven Tri-Taper™ Design Anthropomorphic data, constructed from CT scans of male and female femurs, was used to determine optimal stem design and AP growth. A 12 degree proximal taper provides inherent fixation and rotational stability through increased surface area contact with cortical bone structures. A 4 degree distal taper reduces the possibility of stress shielding and helps account for proximal/distal mismatch. The ML taper of the TaperFill® stem is identical to DJO’s Linear® Hip stem which has demonstrated over 17 years of clinical success. Short Stem for less invasive procedures A shorter stem allows easier insertion into the bone without stressing the muscles, potentially causing undue trauma.
