Ukuhlukana kwe-Distal radius fractures (DRFs) kwenzeka ngaphakathi kuka-3 cm wengxenye ekude yerediyasi, okuwukuphuka okuvame kakhulu ezithweni ezingaphezulu phakathi kwabesifazane abadala kanye nabesilisa abasebasha abadala.Ucwaningo lubike ukuthi ama-DRF enza i-17% yazo zonke iziphuka kanye nama-75% okuphuka kwengalo.

Imiphumela egculisayo ayikwazi ukutholwa ngokuncishiswa okukhohlisayo nokulungiswa kwe-plaster.Lokhu kuphuka kungashintsha kalula esikhundleni ngemva kokuphathwa ngendlela elondolozayo, futhi izinkinga, njengokungaqini kahle kwamathambo ahlangene nokungaqini kwesihlakala, kungase kwenzeke ngasekupheleni.Ukuhlinzwa kwenziwa ukuze kwelashwe ukuphuka kwe-distal radius ukuze iziguli zikwazi ukwenza inani elanele lokuzivocavoca okungenabuhlungu ukuze kubuyiselwe umsebenzi ojwayelekile kuyilapho kuncishiswa ubungozi boshintsho oluwohlokayo noma ukukhubazeka.

Ukuphathwa kwama-DRF ezigulini ezineminyaka engu-60 nangaphezulu kwenziwa kusetshenziswa izindlela ezinhlanu ezivamile ezilandelayo: isistimu yepuleti lokukhiya i-volar, ukulungiswa kwangaphandle okungewona amabhuloho, ukulungisa ibhuloho kwangaphandle, ukufaka izintambo ze-Kirschner nge-percutaneous, kanye nokufakwa kukakhonkolo.

Iziguli ezihlinzwa i-DRF ngokuncishiswa okuvulekile nokulungiswa kwangaphakathi zinengozi enkulu yokutheleleka kwenxeba kanye ne-tendonitis.

Izilungisi zangaphandle zihlukaniswe ngezinhlobo ezimbili ezilandelayo: ezihlanganayo nezingezona ibhuloho.I-cross-articular fixator yangaphandle ikhawulela ukunyakaza okukhululekile kwesihlakala ngenxa yokucushwa kwaso.Izilungisi zangaphandle ezingabhubhisi zisetshenziswa kakhulu ngoba zivumela umsebenzi ohlangene olinganiselwe.Amadivayisi anjalo angenza kube lula ukunciphisa ukuphuka ngokulungisa izingcezu zokuphuka ngokuqondile;zivumela ukuphathwa kalula kokulimala kwezicubu ezithambile futhi akuvimbeli ukunyakaza kwesandla kwemvelo phakathi nesikhathi sokwelashwa.Ngakho-ke, izilungisi zangaphandle ezingabhubhisi ziye zanconywa kabanzi ekwelashweni kwe-DRF.Emashumini ambalwa eminyaka adlule, ukusetshenziswa kwezilungisi zangaphandle zendabuko (i-titanium alloys) sekuthole ukuthandwa, ngenxa ye-biocompatibility yabo enhle kakhulu, amandla aphezulu emishini kanye nokumelana nokugqwala.Kodwa-ke, izilungisi zangaphandle zendabuko ezenziwe ngensimbi noma i-titanium zingase zibangele ama-artifact anzima kumaskeni we-computed tomography (CT), okuholele ekutheni abacwaningi bafune izinto ezintsha zokulungisa izinto zangaphandle.

Ukulungiswa kwangaphakathi okusekelwe ku-polyetheretherketone (PEEK) kuhlolisisiwe futhi kwasetshenziswa iminyaka engaphezu kwe-10.Idivayisi ye-PEEK inezinzuzo ezilandelayo kuzinto ezisetshenziselwa ukulungisa amathambo okuvamile: akukho ukungezwani komzimba nensimbi, i-radiopacity, ukuphazamiseka okuphansi kwe-imaging resonance magnetic (MRI), ukususwa kokufakwa kalula, ukugwema into "yokushisela okubandayo", kanye nezakhiwo ezingcono zokukhanda.Isibonelo, inamandla amahle okuqina, amandla okugoba, namandla okuthinta.

Ezinye izifundo zibonise ukuthi izilungisi ze-PEEK zinamandla angcono, ukuqina, nokuqina kunamadivayisi okulungisa insimbi, futhi banamandla angcono okukhathala13.Nakuba i-elastic modulus yezinto ze-PEEK ingu-3.0–4.0 GPa, ingaqiniswa i-carbon fiber, futhi i-elastic modulus yayo ingaba seduze naleyo ye-cortical bone (18 GPa) noma ifinyelele inani le-titanium alloy (110 GPa) ukushintsha ubude nesiqondiso se-carbon fiber.Ngakho-ke, izakhiwo zemishini ze-PEEK ziseduze nalezo zethambo.Namuhla, isilungisi sangaphandle esisuselwa ku-PEEK senziwe futhi sasetshenziswa emtholampilo.
