Cannulated compression screws yave imwe yeanonyanya kushandiswa uye akakosha kugadzirisa midziyo mukuvhiya kwemazuva ano kwemapfupa. Yakagadzirwa ine hollow yepakati canal inobvumira kuisirwa pamusoro pegwara regwara, aya screws anogonesa kunyatsoiswa, kugadzika kugadzirisa, uye zvishoma invasive maitiro ekuvhiya.
Kugona kwavo kuendesa kudzvanyirira kunodzorwa pamitsetse yekutyoka kunoita kuti ive yakakodzera kugadzirisa matyoka munzvimbo dzakamanikidzwa kana dzakatetepa, kunyanya muhudyu, gumbo, uye mapfupa madiki eruoko netsoka. Chinyorwa ichi chinoongorora akakosha ekiriniki mashandisirwo emakanulated compression screws uye anosimbisa maitiro avanoita ekuvhiya mhedzisiro munzvimbo dzakasiyana dzeanatomical.
Hip Surgery: Yakagadzikana Kugadziriswa kweFemoral Neck Fractures
Mitsipa yevakadzi inoputsika-inowanzoitika pakati pevakuru vakwegura uye varwere vane simba guru-inoda kugadziriswa kwemukati kunovimbika kuti idzorere kufamba uye kudzivirira matambudziko akadai seasina kana avascular necrosis.Cannulated compression screwsndiwo mhinduro yakajairwa nekuda kweiyo yakanyanya kurongeka uye zvishoma invasive nzira yekuisa.
Clinical Muenzaniso:
Murwere ane makore 65 okuberekwa asina kutsemuka mutsipa wechikadzi akatyoka akavharwa kudzikiswa uye kugadziriswa kwemukati nemasikiru matatu akafanana cannulated compression screws. Kutungamirwa neK-waya, ma screws akaiswa mune inverted triangle configuration kuti awedzere biomechanical kugadzikana. Postoperative X-rays yakaratidza kurongeka kwakanakisa uye yakaramba ichidzvanywa. Pamasvondo e12, murwere akaratidza huremu hwakazara huremu nekubatana kwakasimba kweradiographic.
Chikonzero nei Vachishanda Zvakanaka kune Hip Fractures:
Guidewire-inobatsirwa kuiswa inovimbisa yakarurama screw trajectory.
Kudzvinyirirwa kunodzorwa kunovandudza kugadzikana kwekutanga uye kuporesa kwepfupa.
Minimally invasive nzira inoderedza kunyorova kwetishu uye nekukurumidza kupora.
Multiple-screw configurations inowedzera kutenderera uye axial kugadzikana.
Ankle Surgery: Kugadziriswa kweMalleolar uye Talar Fractures
Iyo ankle joint's yakaoma anatomy uye huremu-inotakura zvinodiwa zvinoda kugadzirisa inodyara inopa kudzvanya kwakasimba uye kuchengetedza kurongeka pasi pemakiniki kushushikana. Cannulated compression screws inoshandiswa zvakanyanya kune medial malleolus fractures, lateral malleolus avulsion fractures, uye talar muviri kana kukuvara kwemutsipa.
Clinical Muenzaniso:
Mumwe mutambi wemakore makumi matatu ekuberekwa akatsigira malleolus fracture panguva yekukuvara kwemitambo. Vanachiremba vakadzikisa kutsemuka uye vakaisa masiruu maviri akaiswa cannulated kuti awane kudzvanya panzvimbo yekutyoka. Nzira yakatungamirirwa yakaderedza kukanganiswa kwenyama yakapfava-kunyanya kukosha pamakumbo emakumbo, apo neurovascular structures inenge yakaoma. Murwere akadzokera kukudzidziswa mukati memwedzi mina, achitsigirwa nekugadzirisa kwakagadzikana uye kuunganidza kwekutanga.
Zvakanakira munharaunda yeAnkle:
Yakanakisa kune zvidiki, oblique, kana zvakaoma-kuwana-zvimedu.
Kudzvinyirira kunokurudzira kukurumidza kubatanidzwa kwekanzura pfupa.
Kudzikiswa saizi yekucheka kunodzikisa njodzi yekunetsekana kwepashure.
Inopindirana nedzimwe nzira dzekugadzirisa (semuenzaniso, plate-screw constructs) kune yakaoma fractures.
Diki Bone Fixation: Ruoko, Wrist, uye Foot Fractures
Mabhonzo madiki anoda hardware yakapfava inopa kugadzikana pasina kuwanda kwakawanda. Cannulated compression screws-inowanzo kuwanikwa mudiki madhayamita-yakanakira scaphoid fractures, metacarpal fractures, uye proximal phalanx kukuvara, pamwe nekutsemuka mutsoka, senge navicular uye yechishanu metatarsal.
Clinical Muenzaniso:
Murwere ane makore makumi maviri nemaviri akatyoka chiuno chescaphoid akagadziriswa percutaneous achishandisa siruu isina musoro cannulated compression screw. Iyo screw yakaunza kuenderera mberi kwekumanikidzana mukati mekutyoka, ichigonesa kufamba kwekutanga wrist. Pamavhiki masere, CT scans yakasimbisa kubatana kwemapfupa, uye murwere akatangazve mabasa enguva dzose pasina kuoma.
Chikonzero nei Vachiita Zvakanaka muMabhonzo Madiki:
Headless screw dhizaini inobvisa mukurumbira wehardware uye kushatirwa.
Precision kuiswa kunodzivirira matendon akapoteredza uye nzvimbo dzakabatana.
Kuramba kudzvinyirirwa kunowedzera huwandu hwekubatana mumapfupa ane ropa risina kunaka (semuenzaniso, scaphoid).
Minimally invasive nzira dzinoderedza mavanga uye kupora nguva.
Technical Advantages Kutyaira Zvirinani Kuvhiya Migumisiro
Munzvimbo dzakasiyana-siyana dzeanatomical, cannulated compression screws inogovera akati wandei mabhenefiti anoita kuti asarudzwe nevanovhiya vemapfupa:
Kurongeka Kwepamusoro:
Guidewire-based insertion inoderedza njodzi yekusarongeka.
Consistent Compression:
Zvidimbu zvakarukwa kana zvisina musoro zvigadziriso zvinounza yakadzorwa interfragmentary compression yakakosha pakupora kwakadzikama.
Kusiyana-siyana muKusvika:
Inokodzera zvese zvakavhurika uye percutaneous zvishoma invasive kuvhiya.
Yakaderedzwa Kuvhiya Trauma:
Zvidiki zvidiki zvinotungamira kupfupi nguva dzekushanda uye kukurumidza kugadzirisa.
Biomechanical Simba:
Yakagadzirirwa kumira kutenderera uye axial mitoro, kunyangwe munzvimbo dzinorema senge hudyu nechiziso.
Mhedziso:
Cannulated compression screws inoita basa rakakosha mukugadzirisa mapfupa ekutyoka kwemapfupa, ichipa kunyatsojeka, kugadzikana, uye mabhenefiti anopinda zvishoma pane dzakasiyana siyana dzekiriniki. Ingave yakashandiswa pakutyoka kwemutsipa wemukadzi, kukuvara kwemalleolar, kana kugadzirisa bhonzo muruvoko netsoka, masiruru aya anogara achivandudza mhedzisiro yemurwere uye mitengo yekuporesa. Kuchinjika kwavo kune akasiyana anotomical zvinodiwa uye kupaza mapatani kunoita kuti ive chinhu chakakosha chemazuva ano maitiro emapfupa.
