Primary hip prosthesis Furlong® H-A.C

cementless

Proximal body of Furlong® H-A.C. is designed to fit the metaphysis of the femur; Rectangular cross section of the proximal body provides rotational stability under dynamic loading Load transferred and transmitted by the interface between the prosthesis and cancellous bone Absolute mechanical stability Cone shaped geometric transition between proximal body and cylindrical distal stem; Prevents subsidence Stress transfer creates ‘hoop stressing’ of the cortical bone providing early stable mechanical fixation Deliberately accurate Cylindrical distal stem; Provides correct angular alignment Deliberately over-reamed to promote preferential transfer of load to metaphysis Subsequent formation of ‘cradling’ trabeculae Natural biological fixation 35 years experience of naturally getting the living to bond to the inert JRI unique coating has high crystallinity – resorbs slower Vacuum plasma spray (VPS) technology – resists thermal cracking and gas pores to prevent delamination compared to atmospheric plasma spray (APS) adopted by many companies
