Securus System Design Rationale Revision hip surgery represents a significant challenge to the orthopaedic surgeon and can have a major impact on a hospital’s orthopaedic budget. The Securus femoral revision system has been designed to help meet both the clinical and financial challenges. The range of femoral prostheses and the instrumentation to implant these have been designed to provide a versatile, easy to use and cost effective solution appropriate for the majority of femoral stem revisions. A survey of surgeon opinion indicated that the requirements of an effective femoral revision...

Securus System Design Features Feature Cost effective Concise component range keeps inventory to a minimum. Furlong pedigree The Securus design is based on the Furlong® H-A.C. stem design, which has proved so successful in both primary and revision surgery1, 2. Concise instrumentation The system consists of just 6 trays of instrumentation, simplifying the operative procedure and keeping sterilisation and processing costs to a minimum. Accurate distal locking STEP technique and stable distal targeting jig, which locks securely onto the distal stem, help ensure reproducible location of distal...

Revision Hip Types as a Percentage of all Femoral Revisions.4, 5, 6, 7 Loss Type Minimal loss of metaphyseal cancellous bone. Intact diaphysis. Extensive loss of metaphyseal cancellous bone. Intact diaphysis. Loss of cancellous bone. The metaphysis is not supportive. There remains more than 4 cm of bone in the diaphysis to allow for a scratch fit. The metaphysis is not supportive. There remains less than 4 cm of bone in the diaphysis to allow for a scratch fit. Wide open canal without any appreciable isthmus to support an uncemented stem. Revision Hip Types Securus provides an effective...

Modular Range Full interchangability between modular proximal bodies and distal stems. Modular Proximal Bodies o 133 neck angle Standard and +5mm offset Sizes equivalent to 13mm, 14mm, 15mm and 16mm Furlong® H-A.C. stems 2 body types, standard and Extended Lateral Shoulder (ELS) Modular Distal Stems 250mm and 300mm total lengths bowed 250mm length, distal stem diameters: 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm and 18mm 300mm length, distal stem diameters: 13mm, 14mm, 15mm, 16mm, 17mm and 18mm 2 distal holes for locking screws in the 250mm stem, and 3 distal holes in the 300mm stem

Monobloc Range Maintaining sufficient strength at the interface between the proximal body and the distal stem places limitations on the size of implants which can be offered in the modular configurations. To maximise the flexibility of the system Monobloc 250mm A-P bowed stems in the equivalent of Furlong® H-A.C. 11 and 12 have been included in the Securus range. These stems have 10° anteversion built in and so are available in lefts and rights. All stems feature a 133° neck angle and are available in Standard and High (+5mm) Offset. Monobloc Stems 250mm length Bowed, 10° left and right...

Not all H-A.C. coatings are the same The Furlong® Total Hip Replacement was the first in the world to utilise Hydroxyapatite Ceramic (H-A.C.) coating to promote biological fixation. Since its introduction in 1985 JRI has continued to develop and improve its H-A.C. coating and the way in which it is applied. One of the most important factors is whether the H-A.C. coating is applied in atmospheric (APS) or vacuum conditions (VPS). Supravit® is JRI’s VPS H-A.C coating. Fact: All JRI implants have been VPS coated since 1993 VPS removes oxygen and gas pockets VPS produces a dense homogenous...

Supravit® Zoned H-A.C. Coating Modular proximal femoral bodies and the metaphyseal section of the monobloc stems feature Supravit® Zoned coating. Push-out tests have shown an Increased shear strength at the Surface image of Supravit® Zoned H-A.C. coating H-A.C. to bone interface as a function of surface roughness. There is also an increased surface area of H-A.C. for bone in-growth to promote biological fixation proximally – a great advantage in revision surgery. Surface image of Supravit® H-A.C. coating

Accurate Distal Locking The distal targeting jig references directly from the distal stem, this allows for precise setting of the jig, Targeting jig constructed in titanium for light weight, high strength and stability. Logical sequence of steps for jig set up and use. Stable locking of adjustable components to maintain pre-referenced settings Reproducible accuracy of distal targeting reduces reliance on intra-operative imaging. Two screw holes in the 250mm stems and three screw holes in the 300mm stems accept 4.5mm diameter locking screws Anteversion of the proximal modular body can be...

STEP technique STEP 1 – insert definitive implant and attach pre-assembled jig STEP 2 – introduce the 6mm STEP drill though the tissue protector corresponding to the most proximal of the locking holes and drill through the lateral cortex only. STEP 3 – using the 3.8mm drill bit penetrate through the medial cortex and leave the drill in situ, thereby anchoring the jig in position. STEP 4 – using the standard targeting technique drill the subsequent distal holes and secure with locking screws. STEP 5 – remove the drill from the proximal hole and secure with a locking STEP scr
