Clinically Proven Aseptic loosening – a thing of the past! 1. Survivorship of 38 cases in under 50 year olds. N.N. Shah et al J Bone Joint Surg [Br] 2009; 91B:865-9 2. Survivorship of 331 consecutive cases. J.A.N Shepperd et al J Bone Joint Surg [Br] 2008; 90-B:27-30 3. Survivorship of 134 consecutive cases. A.A. Shetty et al J Bone Joint Surg [Br] 2005; 87-B:1050-4 4. Survivorship in 2,212 cases. J.M.

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 have continued to develop and improve our 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...

Furlong® H-A.C. Femoral Stem – Design Rationale Elimination of Subsidence “Radiological assessment of the femoral components did not show any radiolucent lines and serial radiographs did not reveal any evidence of subsidence”1 “The collar on the femoral component prevents early subsidence of the prosthesis after implantation. Once bone has bonded to the prosthesis, its function becomes redundant”2 “There were no reactive lines at the bone-stem interface, no changes at the interface and no subsidence or osteolysis in any of the radiographs studied”3 “Initial stability of the stem is by interference...

A cone shape prosthesis, as distinct from a wedge, when impacted firmly into the metaphysis creates “hoop stressing” which in general terms, is well tolerated by cortical trabecular bone. The deliberate accurate nature of the Furlong® instrumentation and surgical technique ensures precise primary mechanical fixation. The stem shape from the cone section upwards guarantees maximum proximal loading in Gruen zones 1 & 7 and 2 & 6. This allows Gruen zones 2&6 for confident post operative weight bearing and good early bone growth. Cross Section Furlong® H-A.C. Femoral stem histology Gruen zones Cross...

Furlong® H-A.C. Femoral Stem – Design Rationale Elimination of thigh pain “Anterior thigh pain has been reported previously with the use of uncemented hip prosthesis. This was not the case in our study”2 “All patients were asked at each review about the occurrence of anterior thigh pain. None had experienced this at any stage”1 “Another significant feature of our study was the absence of thigh pain, in contrast with reports of other cementless femoral components without H-A.C.

• Proximal body designed to fit the metaphysis of the femur – load transferred to and transmitted by the interface between prosthesis and cancellous bone – rectangular cross section of proximal body provides rotational stability under dynamic loading • Cone shaped geometric transition between proximal body and cylindrical distal stem – prevents subsidence and creates ‘hoop stressing’ of the cortical bone providing early stable mechanical fixation • Hydroxyapatite ceramic coating over the full length of the prosthesis – new bone grows primarily on and directly into the ceramic surface; fully coated...

Furlong® H-A.C. CSF plus Acetabular Cup System Based on the clinically proven design of the Furlong® H-A.C. CSF Acetabular Cup the CSF plus system offers all the same benefits but with some key improvements.6,7,8 Dedicated Range of Acetabular Shell types • The application of 175μm Rough Titanium increases the surface area by 200%. This roughened surface significantly increases the coefficient of friction giving a superior scratch fit • Push-out tests have shown an Increased shear strength at the H-A.C. to bone interface as a function of surface roughness • The roughened surface increases the...

Highly Cross Linked Polyethylene CLP75® During the manufacturing process radiation is used to “crosslink” the polyethylene chains resulting in a more durable material. • Gamma irradiated at 7.5Mrads producing 97.5% crosslinking which significantly reduces volumetric wear • Melt annealed to remove free radicals and restore mechanical properties, reducing oxidation • Calcium stearate free CLP75® and Ultra High Molecular Weight Polyethylene (UHMWPE) liners have a unique 5 degree taper which; • Provides secure non destructive locking mechanism • Secures seating of the liner • Ensures coupling is...

CSF plus Ceramic Bearing Options All ceramics used in the Furlong® H-A.C. CSF plus Ceramic bearing Cup are Biolox® delta Ceramics; This system allows for the largest internal diameter bearing size to be used with the smallest outside diameter cup size, without any compromise to the strength of the implants. • 36mm Biolox® delta Ceramic Head in a • 40mm Biolox® delta Ceramic Head in a 54mm Acetabular Shell • An 18º internal taper provides excellent fixation of the liner in the shell Function Head Size (mm) 40 Maximise Suvivorship Optimise Function​ Increased Stability, Range of Motion5 Alumina...
