Foreword
The ICRC polypropylene technology
Sinceitsinceptionin1979,theICRC’sPhysicalRehabilitationProgrammehaspromotedtheuseoftechnologythatisappropriatetothespecificcontextsinwhichtheorganizationoperates,i.e.,countriesaffectedbywarandlow-incomeordevelopingcountries.
Thetechnologymustalsobetailoredtomeettheneedsofthephysicallydisabledinthecountriesconcerned.
Thetechnologyadoptedmustthereforebe:
• durable,comfortable,easyforpatientstouseandmaintain;• easyfortechnicianstolearn,useandrepair;• standardizedbutcompatiblewiththeclimateindifferentregionsoftheworld;• low-costbutmodernandconsistentwithinternationallyacceptedstandards;• easilyavailable.
Thechoiceoftechnologyisofgreatimportanceforpromotingsustainablephysicalrehabilitationservices.
Forallthesereasons,theICRCpreferredtodevelopitsowntechniqueinsteadofbuyingready-madeorthopaediccomponents,whicharegenerallytooexpensiveandunsuitedtothecontextsinwhichtheorganizationworks.ThecostofthematerialsusedinICRCprostheticandorthoticdevicesislowerthanthatofthematerialsusedinappliancesassembledfromcommercialready-madecomponents.
WhentheICRClauncheditsphysicalrehabilitationprogrammesbackin1979,locallyavailablematerialssuchaswood,leatherandmetalwereused,andorthopaediccomponentsweremanufacturedlocally.Intheearly1990stheICRCstartedtheprocessofstandardizingthetechniquesusedinitsvariousprojectsaroundtheworld,forthesakeofharmonizationbetweentheprojects,butmoreimportantlytoimprovethequalityofservicestopatients.
Polypropylene(PP)wasintroducedintoICRCprojectsin1988forthemanufactureofprostheticsockets.Thefirstpolypropyleneknee-jointwasproducedinCambodiain1991;othercomponentssuchasvariousalignmentsystemswerefirstdevelopedinColombiaandgraduallyimproved.Inparallel,adurablefoot,madeinitiallyofpolypropyleneandEthylVinylAcetate(EVA),andnowofpolypropyleneandpolyurethane,replacedthetraditionalwooden/rubberfoot.
In1998,aftercarefulconsideration,itwasdecidedtoscaledownlocalcomponentproductioninordertofocusonpatientcareandtrainingofpersonnelatcountrylevel.
