Pelvic tumor ndeimwe yemhando dzakaoma uye dzakaoma dzekuvhiya bundu remabhonzo, uye kubviswa kwebundu kunogona kukonzera kurasikirwa kukuru kwebhonzo.Iyo anatomical chimiro uye morphology yepelvis yakaoma kuenzaniswa nedzimwe nzvimbo.Uyezve, pelvis iri padhuze nenhengo dzakakosha mudumbu remudumbu neakawanda akapoterera zvinyoro zvinyoro zvimiro, saka kune matambudziko akakura mukuronga kwekutanga uye intraoperative manejimendi.
Muchigadziro chekugadzirira kweprosthesis, nzvimbo yekugadziriswa inoda kugadziriswa maererano nekurwara kwemurwere, uyezve kugadziriswa kwenzvimbo yakakanganiswa uye kuiswa kweprosthesis kunoda kurongwa maererano nenzvimbo yekudzorera.
Kuomerwa kwekugadzira "pelvic tumor prosthesis" hakungori muchimiro chakaoma chechiuno chechiuno chete asiwo inyaya yekuti nzvimbo dzekufungidzira dzemurwere dzinosiyana kubva pamunhu kuenda kumunhu, saka magadzirirwo eprosthesis anogona kuenderana zvirinani zvinodiwa nemurwere uye kubudirira. mhedzisiro yekuvhiya yakanakisa chinhu chakakosha mukubudirira kwekuvhiya.
LDK mainjiniya anoongorora mumwe nemumwe wemurwere akasiyana morphological, nzvimbo yekurasikirwa kwepfupa uye mechanical nharaunda umo prosthesis ichagara, "Personalize" nzvimbo yakavakwa patsva uye ita kombiyuta kuenzanisa kwekukodzera uye kuseka-up kuti uone kuti prosthesis. inogona kuiswa intraoperative.Muchinyorwa chino, takasarudza 6 anomiririra bundu prosthesis magadzirirwo eakasiyana pelvic bundu kupatsanurwa mumakore mashanu apfuura ereferensi uye hurukuro.
1 dunhu I Pelvis bundu
Nyaya iyi ibundu repa pelvic region I nekubatanidzwa kwejoint ye sacroiliac.Magumo ekupfuura aive osteotomized kuburikidza ne sacroiliac joint kumucheto kwekunze kwe sacral foramen, uye iyo distal kuguma yaive osteotomized yakatwasuka kubva kune acetabular apex kumusoro.Yakagadzirirwa pelvic prosthesis yakashandiswa kugadzira patsva bapiro reiriac.Chimiro uye saizi yeprosthesis yakagadziridzwa kune hurema hwemurwere, uye iyoprosthesis-bone interface(kusangana nesacral uye iliac bones) yakagadzirirwa kutevedzera porous mesh yebhonzo trabeculae kuti iite kuti bone ingrowth uye ibudirire kwenguva refu kugadzirisa kweprosthesis.Iyo posterior rusvingo rweacetabulum ine imwe-chidimbu yakadhindwa ndiro yesimbi uye nail bar system inogona kusungirirwa kumucheto kumashure kweprosthesis kuti ivandudze kugadzikana kweprosthesis.
2 Dunhu II Bundu rePelvis
Murwere aiva nechirwere chiduku uye chete chikamu cheacetabular resection chakaitwa, ine vertical osteotomy mu acetabulum yemurwere uye osteotomy yakadzika pamucheto wepamusoro weacetabulum, nekubviswa kwepubic bone uye kuchengetedzwa kwebazi re sciatic.A customized pelvic prosthesis yakadhindwa muchidimbu, ine prosthesis-bone interface yakagadzirwa kutevedzera porous mesh yetrabeculae.Iyo dhayamita yekunze yeacetabulum yemurwere yakayerwa uye kapu yakasimbiswa yeacetabular inofananidzwa nemurwere acetabular dimensions yakatemwa kuva nheyo yekuvakazve, neplate yakadhindwa mune imwe chidimbu kunze kweprosthesis.Iyi sarudzo yakawedzera kuchengetedzwa kwebazi re sciatic uye chikamu cheacetabulum kune murwere uye yakawana kunyatsogadziriswa uye kuvakazve.
3 Dunhu I + II bundu repelvis
Muchiitiko ichi, bundu rakaitika kuRegion I + II, iyo lateral sacral osteotomy yakacheka sacroiliac joint.matavi e pubic uye sciatic akachengetedzwa maererano nemamiriro ekushanda.Iyo yekubata kumeso kweyakagadziridzwa pelvic prosthesis ine sacrum yakagadzirwa kuita mesh ine porous kutevedzera bhonzo trabeculae, ine chivharo chakagadzirirwa kuzorora padivi remukati resacrum.Iyo yakagadziridzwa iliac rutsigiro uye kapu yeacetabular inounganidzwa zvakasiyana uye inogadziriswa intraoperatively kuti zvive nyore uye zvakavimbika zvakabatanidzwa.Mitsara miviri yemakomba ezvipikiri yakachengeterwa kusungirirwa kwematavi akachengetwa epubic uye sciatic.
4 Dunhu I + II bundu repelvis
Muchiitiko ichi, bundu rakaitika kuRegion I + II, iyo lateral sacral osteotomy yakacheka sacroiliac joint.matavi e pubic uye sciatic akachengetedzwa maererano nemamiriro ekushanda.Iyo yekubata kumeso kweyakagadziridzwa pelvic prosthesis ine sacrum yakagadzirwa kuita mesh ine porous kutevedzera bhonzo trabeculae, Iyo yekumashure side ye prosthesis inogona kubatanidzwa kune mbambo yezvipikiri, kureba uye kutaridzika kwe screws pa sacrum inogadziriswa kubva kune murwere. CT data uye mupendero wekunze we prosthesis yakagadzirwa nemutsara wemaburi e suture kufambisa kugadziriswa kwezvinyoro zvinyoro.
5 Dunhu II + III pelvis bundu
Nyaya iyi ibundu papelvis II + III ine horizontal osteotomy kubva kune yepamusoro acetabular rim.Iyo prosthesis inogadzirwa neyakagadzirirwa pelvis uye pubic bone yekunamatira ndiro.Saizi yekusangana pamusoro peiyo yakagadzirirwa pelvis prosthesis yakagadzirwa zvinoenderana nechimiro cheiyo osteotomy pamusoro uye inosimbiswa nekunze kwechidimbu chimwe chakadhindwa ndiro.Iyo pubic bone yekunamatira ndiro inogadziriswa kune yepakutanga yemurwere pubic bone chimiro uye inonamirwa kune ine hutano rutivi rwepubic bone.
6 Dunhu IV pelvis bundu
Muchiitiko ichi, bundu rakaitika panharaunda IV, mativi ekurudyi nekuruboshwe akanga akaitwa osteotomized kubva pajojo re sacroiliac, kuchengetedza chikamu che olecranon, uye prosthesis yakabatanidzwa kune iriac bone kumativi ose uye kumucheto wezasi wechishanu vertebra.Iyo yakasarudzika pelvic prosthesis inodhindwa muchidimbu uye ine screws ye lumbar vertebrae uye kurudyi nekuruboshwe mativi zvakateerana, paine mukana wekubatanidza staple system kudivi rekumashure.
