Iteknoloji yokubethela i-intramedullary yindlela esetyenziswa kakhulu yokubopha amathambo ngaphakathi. Imbali yayo inokulandelwa emva kwiminyaka yoo-1940. Isetyenziswa kakhulu kunyango lwamathambo amade aqhekekileyo, ama-nonions, njl.njl., ngokubeka isikhonkwane se-intramedullary embindini we-medullary cavity. Lungisa indawo apho kwaqhekeka khona. Kule micimbi, siza kwazisa umxholo ofanelekileyo kuwe malunga nezikhonkwane ze-intramedullary.
Ngamafutshane, uzipho lwe-intramedullary lulwakhiwo olude olunemingxuma emininzi evalekayo kwizikrufu zombini ukuze kulungiswe iziphelo ezikufutshane nezikude zokwaphuka. Ngokwezakhiwo ezahlukeneyo, zinokwahlulwa zibe ziqinileyo, ezityhubhu, ezivulekileyo, njl.njl., ezifanelekileyo kwizigulana ezahlukeneyo. Umzekelo, uzipho lwe-intramedullary oluqinileyo alunakumelana nosulelo kuba alunandawo yangaphakathi efileyo. Amandla angcono.
Ukuthatha umzekelo we-tibia, ububanzi bomngxuma we-medullary buyahluka kakhulu kwizigulana ezahlukeneyo. Ngokuxhomekeke ekubeni kufuneka ukujijwa kweenzipho, izipikili ze-intramedullary zinokwahlulwa zibe zii-reamed nails kunye nee-non-reamed nails. Umahluko ulele ekubeni kufuneka kusetyenziswe ii-reamers xa kujongwa i-medullary, kuquka izixhobo zesandla okanye zombane, njl.njl., kwaye kusetyenziswa ii-drill bits ezinkulu ngokulandelelana ukwandisa umngxuma we-medullary ukuze kungene izipikili ze-intramedullary ezinkulu.
Nangona kunjalo, inkqubo yokwandiswa kwe-marrow yonakalisa i-endosteum, njengoko kubonisiwe kumfanekiso, kwaye ichaphazela inxalenye yomthombo wegazi wethambo, nto leyo enokubangela i-avascular necrosis yexeshana yamathambo asekuhlaleni kwaye yonyuse umngcipheko wosulelo. Nangona kunjalo, kunxulumene nezifundo zeklinikhi ziyala ukuba kukho umahluko omkhulu. Kukwakho nezimvo eziqinisekisa ixabiso lokufakelwa kwe-medullary. Kwelinye icala, iinzipho ze-intramedullary ezineedayamitha ezinkulu zingasetyenziselwa ukufakwa kwe-medullary. Amandla kunye nokuqina kuyanda ngokunyuka kobubanzi, kwaye indawo yokunxibelelana ne-medullary cavity iyanda. Kukwakho nombono wokuba ii-chips ezincinci zamathambo eziveliswa ngexesha lenkqubo yokwandiswa kwe-marrow nazo zidlala indima ethile ekufakweni kwethambo le-autologous.
Ingxoxo ephambili exhasa indlela yokungaxutywanga kukuba inokunciphisa umngcipheko wosulelo kunye ne-pulmonary embolism, kodwa into engenakuyityeshelwa kukuba ububanzi bayo obuncinci buzisa iipropati ezibuthathaka zoomatshini, nto leyo ebangela ukuba kuphinde kusebenze kwakhona izinga eliphezulu. Okwangoku, uninzi lwezipikili ze-intramedullary tibial zivame ukusebenzisa izipikili ze-intramedullary ezandisiweyo, kodwa izinto ezilungileyo nezingalunganga zisafuneka zilinganiswe ngokusekelwe kubukhulu bomngxunya we-medullary wesigulana kunye neemeko zokuqhekeka. Imfuneko ye-reamer kukunciphisa ukungqubana ngexesha lokusika kwaye ibe ne-flute enzulu kunye ne-shaft encinci yobubanzi, ngaloo ndlela kunciphisa uxinzelelo kumngxunya we-medullary kwaye kuthintelwe ukugqithisa kakhulu kwamathambo kunye nezicubu ezithambileyo ezibangelwa kukungqubana. I-Necrosis.
Emva kokuba uzipho lwe-intramedullary lufakiwe, kufuneka ukufakelwa kwezikrufu. Ukufakelwa kwendawo yezikrufu ngokwesiko kuthiwa yi-static locking, kwaye abanye abantu bakholelwa ukuba kunokubangela ukuphola okulibazisekileyo. Njengendlela yokuphucula, eminye imingxunya yezikrufu ezitshixwayo yenzelwe ukuba ibe yimo ye-oval, ebizwa ngokuba yi-dynamic locking.
Oku kungasentla yintshayelelo kwizinto ezisetyenziswa ekufakeni iinzipho ngaphakathi kwe-medullary. Kwiphepha elilandelayo, siza kwabelana nawe ngenkqubo emfutshane yotyando lokufakeni iinzipho ngaphakathi kwe-medullary.
