Intangiriro ya Poliaxial Screws-I

Poliaxial Pedicle Screwbyahinduye urwego rw'ubuganga bw'umugongo, bituma abaganga babasha koroherwa no gutuza mu gihe cyo kubaga umugongo. Ibi bikoresho bishya byagenewe kwakira inguni zitandukanye zo gushyiramo uruziga, bitanga ubworoherane mu guhuza no gukosora umugongo.

Akamaro nyamukuru kavis za pedicle za titanium y'umugongoishingiye ku miterere yayo yihariye y’umupira n’agasogisi. Ibi bituma screw izenguruka mu nkoni, bigatuma umuganga ubaga ashobora guhindura inguni yayo nyuma yo kuyishyiramo. Uku guhinduka kw’ubworoherane ni ingenzi cyane mu kuvura ubumuga bukomeye bw’umugongo, aho gushyira neza urwego rw’inyuma rw’umugongo ari ingenzi kugira ngo ubuvuzi bugende neza. Bitewe n’utugozi twa polyaxial twemerera guhindura nyuma yo kuyishyiramo, bifasha kugabanya ibyago byo guhura n’ingorane zijyanye no kugorana.

Uretse kuba umuntu ubasha guhuza n'imimerere neza,screw y'ikirengeNanone itanga uburinzi buhanitse kurusha vis zisanzwe za monoaxial. Ubu bushobozi bwo gufunga vis mu byerekezo bitandukanye byongera uburinzi rusange bw'imiterere, ibyo bikaba ari ingenzi cyane mu kubungabunga uburinzi bw'umugongo mu gihe cyo gukira. Ibi ni ingenzi cyane mu gihe cyo kubaga spinal fusion, aho intego ari uguteza imbere gukura kw'amagufwa no kugera ku guhuza neza hagati y'amagufwa n'imigongo.

Ubugari bwasisitemu yo gukurura ibirenge by'umugongobiterwa n'uburyo umurwayi akoresha n'ibyo akeneye mu miterere ye. Ubusanzwe, ibivis yo gupfuka umugongoIngano y'umurambararo kuva kuri mm 4.0 kugeza kuri mm 7.0. Guhitamo umurambararo ni ingenzi cyane, kuko bigira ingaruka ku mbaraga z'ingufu, ku buryo ihagarara, ndetse n'imiterere rusange y'ibinyabuzima.Uruti rw'umugongo rwa pedicleifite uburebure bunini muri rusange itanga imbaraga n'ubudahangarwa, bigatuma ikwiriye abarwayi bafite ubucucike bw'amagufwa bwinshi cyangwa abakeneye gufatirwa neza kurushaho.
