Maonero: 0 Munyori: Saiti Edhita Nguva Yekuburitsa: 2025-01-18 Mabviro: Site

1.Chii chinonzi femoral stalk

Nhanganyaya:

Dzinde remukadzi (Femoral Stem) chikamu chesimbi inoshandiswa kutsiva chikamu chepamusoro chemboro yemurwere (chidya chebhonzo) mukuvhiya kwekutsiva hudyu. Icho chimwe chezvinhu zvinonyanya kukosha zvekugadzirwa kwehudyu system uye ine basa rekubatanidza kune musoro wemukadzi uye kutora mitoro uye kufamba kwekubatana kwehudyu. Basa guru rehudyu yehudyu nderekufambisa kufamba kwehudyu yejojo uye chikamu chezasi kune imwe yakasara yehudyu yakagadzirwa, kuve nechokwadi chokuti chibatanidza chakadzikama, chakasununguka uye chinoshanda zvakanaka.

Chimiro uye kushanda kwechikadzi chechikadzi

Chimiro:

Dzinde remukadzi rinowanzoita tapered kana cylindrical uye rakagadzirirwa kuenzanisa chimiro cheanatomical chemukadzi wemunhu. Inodzorera basa rekubatana kwehudyu kuburikidza nekuisa mukati memukadzi uye kubatanidza kune musoro wechikadzi (chimwe chikamu chekubatana kwehudyu yakagadzirwa).

Basa:

Dzinde remukadzi rinotakura huremu hwepamusoro hwemuviri hwepamusoro, saka rinoda kuve nekukwanisa kutakura mutoro wakasimba uye kugadzikana. Inofanirawo kuve biocompatible kuve nechokwadi che osseointegration panguva yekushandiswa kwenguva refu.

Mhando uye magadzirirwo echikadzi stems

Mhando dzechikadzi dzinde

Kune marudzi akasiyana-siyana echikadzi shanks uye akajairika anosanganisira:

Round shank:

Inokodzera varwere vane inenge yakatenderedza femoral anatomy, iri nyore kuisa, asi inogona kunge isina kusungirirwa zvakachengeteka mune vamwe varwere vane osteoporosis.
Pamusoro pezvo, zvakanakira masheki akatenderedza anosanganisira nzira dzakareruka dzekuvhiya uye nguva pfupi yekuisirwa. Nekudaro, zvinofanirwa kucherechedzwa kuti kune varwere vane low bone mineral density kana osteoporosis, mamwe akakodzera echikadzi stem marudzi angada kutariswa kuti ave nechokwadi chekugadzikana kwenguva refu.

Tapered shank:

Inowanzo shandiswa muvarwere vane tapered femoral anatomy uye tapered kana nhete yefemoral dzinde kubatsira kuchengetedza iyo femoral stem.

Shanks inogadziriswa:

Mamwe mashangi echikadzi akagadzirwa ane zvinochinjika zvinokwanisa kuchinjirwa kuchimiro chemurwere.

Progressive shanks:

Aya mashangi akagadzirirwa kupa akasiyana madhigirii ekugadzikana uye kugoverwa kwemutoro kuti ugone hunhu hwakasiyana hwemapfupa uye zvinodiwa nemurwere.

Femoral shanks ane coatings:

Zvakadai sesimende kana cementless (kureva, osseointegrated), zvichienderana nehutano hwemapfupa emurwere uye chimiro chemukadzi. Iyo cemented version inokodzera varwere vakwegura, nepo osseointegrated version yakakodzera varwere vane hutano huri nani hwemapfupa.

Magadzirirwo echikadzi stem anowanzo kusanganisira:

Kutariswa kwekugadziriswa kweanatomical, senge kona, kureba, uye kukombama kwedzinde remukadzi. Sarudzo inoitwa kuti ive nechokwadi chekuti dzinde remukadzi rinosangana zvakanaka nefemu uye rinoramba rakagadzikana.
Adjustable dhizaini: Mamwe madzinde echikadzi akagadzirwa ane anochinjika maficha anobvumira kuti zvimwe zvigadziriso zviitwe panguva yekuvhiyiwa kuti zvigadzirise kune akasiyana anatomical zvimiro.

3.Ndeapi mamiriro angashandisa tsinde yemukadzi

Kupi kushandisa mubato wechikadzi

3.1. Osteoarthritis yehudyu (osteoarthritis)

Mamiriro ezvinhu

Ichi ndicho chiitiko chinonyanyozivikanwa chinoshandiswa chikadzi chechikadzi. Cartilage yehudyu yemurwere inoderera, zvichiita kuti majoini arwadziwe, aite zvishoma, uye dyskinesia. Sezvo mamiriro acho achifambira mberi, mazamu echikadzi uye acetabulum anokonzerwa nekupfeka kwakanyanya uye kubvarura, zvichiita kuti kurasikirwa kukuru kwekubatana.

Chinangwa Kuvhiya:

Kuburikidza nekugadzirwa kwehudyu kutsiva kuvhiyiwa, dzinde remukadzi rinoshandiswa kutsiva chikamu chakakanganisika chemukadzi, nokudaro kudzorera basa rekubatana kwehudyu, kubvisa marwadzo, nekuvandudza hupenyu hwemurwere.

3.2. Femoral head necrosis (Avascular Necrosis, AVN)

Mamiriro ezvinhu

Femoral head necrosis kufa kwebhonzo mumusoro wemukadzi nekuda kwekukanganiswa kweropa. Izvi zvinowanzokonzera kurwadziwa kwakanyanya kwemajoini uye kurasikirwa kwebasa. Necrosis yemusoro wevakadzi inogona kukonzerwa nezvikonzero zvakasiyana-siyana, zvakadai sekushandiswa kwenguva refu kwemishonga ye steroid, kushungurudzika, uye kudhakwa kwedoro.

Kuvhiya Chinangwa:

Kana femoral head necrosis isingagone kudzoserwa kuburikidza nekuchengetedza kurapa, yekugadzira hudyu inotsiva kuvhiyiwa inova nzira yekurapa. The femoral stem inoshandiswa kutsiva necrotic chikamu chemusoro wemukadzi uye kudzorera basa rekubatana.

3.3. Femoral Fracture

Mamiriro ezvinhu

Kunyanya muvarwere vakwegura, femoral mutsipa kuputsika kana femoral stem fractures zvinowanzoputika hudyu. Kunyanya, kuputika kwemutsipa wevakadzi kunogona kuda kugadziriswa kwehudyu yekugadzira kana kuputsika kuchikundikana kupora kana kana pane zvinetso zvakadai se osteoporosis.

Kuvhiya Chinangwa:

Kutsiva chikamu chakakanganisika chemukadzi kuburikidza nekuiswa kwechikadzi stem kuitira kudzorera hudyu yemurwere, kuderedza marwadzo, nekuvandudza kufamba. Iyo femoral stem isarudzo inodiwa kune varwere vane zvakanyanya kutsemuka mafractures kana kupora kwakaoma.

3.4. Hip Joint Infection (HJI)

Mamiriro ezvinhu

Mune zvimwe zviitiko, mubatanidzwa wehudyu unogona kukanganisa kubatana nekuda kwehutachiona hwehutachiona, kunyanya yechipiri kune hutachiona hunoitika mushure mekuvhiyiwa kwehudyu (semuhudyu prosthesis infection). Utachiona uhwu hunogona kutungamirira kukukuvara kwakanyanya kune zvinyoro zvinyoro uye pfupa, kana kunyange kurasikirwa kwakakwana kwebasa rekubatana.

Kuvhiya Chinangwa:

Mushure mokunge hutachiona hwave huchidzorwa, kushandiswa kwehudyu yakagadzirwa kunogona kudiwa kuti udzorere basa rekubatana. Muchiitiko ichi, iyo femoral stem ichashandiswa kutsiva iyo yakakuvadzwa kana utachiona chikamu chemukadzi.

Mamiriro ekushandiswa kwechikadzi

3.5. Hip Deformity kana Developmental Dysplasia yeHip (DDH)

Mamiriro ezvinhu

Vamwe varwere vanogona kuberekwa nekukura dysplasia yehudyu (semuenzaniso, hip dislocation kana acetabular asymmetry), uye izvi zvinokanganisa zvinogona kutungamirira kuhutano husina kunaka pakati pemukadzi uye acetabulum, zvichiita kuti kutanga kuderera kwekubatana, kurwadziwa, kana kusashanda.

Zvinangwa zvekuvhiya:

Muzviitiko zvekusimudzirwa kwehup dislocation kana humwe hudyu hunokanganisa zvakanyanya hupenyu hwehupenyu, kuvhiyiwa kwehudyu kunotsiva kunogona kudiwa, umo chidzitiro chechikadzi chinoshandiswa kutsiva chikamu chakakanganisika chemukadzi uye kudzorera kushanda pamwe chete.

3.6. Rheumatoid Arthritis (Rheumatoid Arthritis)

Mamiriro ezvinhu

Rheumatoid arthritis chirwere chekudzivirira muviri chinowanzo tungamira mukuzvimba kusingaperi uye kukuvadzwa kwecartilage mumajoini. Kana hudyu ichikanganiswa, kufamba kwejoini kunogumira uye kurwadziwa uye kusashanda zvakanaka kunowedzera kuipa.

Kuvhiya Chinangwa:

Artificial hip replacement mushonga unoshanda wekukuvara kwakanyanya kujoinhi rehudyu kunokonzerwa nerheumatoid arthritis. Iyo femoral stem inoshandiswa mukuvhiya kutsiva chikamu chakakanganisika chemukadzi, nekudaro kuderedza marwadzo uye kudzorera majoini kufamba.

3.7 Slipped Capital Femoral Epiphysis (SCFE)

Mamiriro ezvinhu

Slipped Capital Femoral Epiphysis (SCFE) inowanzoitika panguva yekukura nekukura kwevechiri kuyaruka, kunyanya panguva yekuyaruka, uye inogona kukonzera kusarongeka kana kutsvedza pakati pemusoro wemukadzi uye dzinde remukadzi. Mamiriro aya, kana akasiyiwa asina kurapwa, anogona kutungamirira mukuparara kwemajoini kana kurasikirwa kwebasa.

Kuvhiya Chinangwa:

Mune zvimwe zviitiko, misoro yevakadzi yakatsvedza haigone kudzoserwa nekurapa kwekuchengetedza uye ingangoda kuvhiyiwa kwehudyu yekutsiva. A femoral stem inogona kushandiswa kutsiva chikamu chakakanganisika chemukadzi uye kudzorera yakajairika majoini basa.

3.8. Kudzokorora kana Kutsiva mushure meHip Arthroplasty (Revision Hip Arthroplasty)

Mamiriro ezvinhu

Artificial hip replacement surgery inogona kubudirira zvikuru, asi nekufamba kwenguva prosthesis inogona kupera, kusunungura, kana kukundikana, zvichiita kuti kurasikirwa kwekushanda kwemajoini kana kurwadziwa kunoramba kuripo. Hip kugadzirisa kana kutsiva kuvhiyiwa kungave kuri madikanwa panguva ino.

Chinangwa Kuvhiya:

Panguva yekuvhiyiwa kana kuchinjwa, dzinde remukadzi ringada kutsiviwa kana kugadziridzwa kuti rienderane nezvinodiwa zvitsva zvemurwere. Kakawanda, chidzitiro chechikadzi chichasarudzwa nechigadzirwa chitsva kana zvinhu zvichibva pakupfeka uye kusununguka kweprosthesis.
