I. Nei sikuruu dzine kannule dzine buri?
Masisitimu ezvikururu zvine kannusheni anoshanda sei? Kushandisa waya dzakatetepa dzeKirschner (K-waya) dzakaboorwa mubhonzo kuti dzitungamire nzira dzezvikururu nemazvo muzvidimbu zvidiki zvemapfupa.
Kushandisa waya dzeK kunodzivirira kuboorwa kwemaburi epilot zvakanyanya uye kunobvumira kugadzika kwezvidimbu zvemapfupa zviri pedyo panguva yekuiswa kwesikuruu. Zvishandiso zvisina maburi uye masikuruu asina maburi zvinoiswa mubhonzo pamusoro pewaya dzeK. Kugadzika kwesikuruu necannulated kunobatsira mumusana wemuromo wechibereko kudzikamisa kupwanyika kweondontoid uye kurapa kusagadzikana kweatlantoaxial.
Zvikuruu zvine kannuru zvine zvakanakira zvakawanda zvichienzaniswa nezvikuruu zvisina kannuru: 1) waya dzeK dzinotungamira nzvimbo yekuruu mubhonzo;
2) nzira yeK-wire inochinja nzvimbo zviri nyore kana nzira yekutanga yakanga isina kunaka;
3) waya dzeK dzinobvumira kugara uchiisa zvidimbu zvemapfupa zvisina kugadzikana zviri pedyo;
4) Waya dzeK dzinodzivirira kufamba kwezvidimbu zvemapfupa zvisina kugadzikana panguva yekuisa sikuruu.
Matambudziko ane chekuita neK-waya (kutyoka, kuisa panzvimbo itsva, uye kufambira mberi) anogona kuderedzwa uchishandisa nzira dzakanyatsojeka dzekuvhiya. Sisitimu yakakosha yezvishandiso zve screw yakagadzirwa zvakanangana nekuisa pamusoro pemuromo wechibereko kuti ibvumire kubhoorwa kwepercutaneous uchishandisa zvishandiso zve tunneling refu, tissue sheaths, drill guides, uye K-waya refu. Zvishandiso izvi zvinobvumira kuendeswa kwe screws dzakabhoorwa ne angle yakaderera kumusana kuburikidza ne trajectories refu dzakapfava. Zvisikuru zve cannulated zvine mabhenefiti akakosha zvichienzaniswa nezvisikuru zvisina kubhoorwa zvekugadzirisa musana wechibereko usina kugadzikana pa system.
II. Ndeipi screws dziri nani dzecannulated kana intrameduallary nails?
Nzara dzemukati memedullary nedzakaiswa muchubhu zvishandiso zvekurapa zvinoshandiswa kugadzirisa kukuvara kwemukati. Chimwe nechimwe chine zvachinobatsira uye chakakodzera mhando dzakasiyana dzekukuvara uye zvinodiwa pakurapwa.
| Rudzi | Zvakanakira |
| Chipikiri cheIntramedullary | Kugadzika kwembambo mukati memedullary kwakanaka pakutyoka kwakasimba kwemapfupa marefu, uye kukuvara kushoma uye kubuda ropa kushoma. Kugadzika kwembambo mukati memedullary kunoshandiswa pakugadzirisa central. Kana zvichienzaniswa nemaplate esimbi, mbambo mukati memedullary dzinogonawo kuchengetedza kusimba kwemembrane inobuda mumuviri, kudzivirira kupora kwekutyoka kunonoka, uye kuita basa rekudzivirira hutachiona. |
| Screw ine kanivhasi | Inonyanya kushandiswa munzvimbo dzakadai sekutyoka kwemutsipa wefemoral, ine mhedzisiro yakakosha yekugadzirisa uye yekumanikidza. Uyezve, kukuvara kwacho kudiki kwazvo uye hapana maplate esimbi anodiwa. |
III.Ndirini paunofanira kushandisa screws dzinobvisa tsvina kana kuti dzinodzivirira kubva ku cortical?
Zvikuruu zvinodzima nezvinodzima zvecortical zvese zviri zviviri mhando dzezvikafu zvemapfupa zvinoshandiswa pakugadzirisa mapfupa, asi zvakagadzirirwa mhando dzakasiyana dzemapfupa uye zvine mashandisirwo akasiyana:
Zvikuruu Zvinodzima Zvakagadzirwa kuti zvishandiswe mumapfupa asina kusimba, asina kusimba, uye asina kusimba, anowanzo kuwanikwa kumagumo emapfupa marefu, akadai sefemur netibia. Anowanzo shandiswa munzvimbo dzine mapfupa ane maburi akawanda uye asina kusimba, akadai senzvimbo dzemapfupa marefu. Anowanzo shandiswa mukurapa kwemusana, pelvis, uye dzimwe nzvimbo dzefudzi nechiuno.
Cortical Screws yakagadzirirwa kushandiswa mumapfupa e cortical denser, ayo anoumba chikamu chekunze chemapfupa mazhinji uye akaomarara uye akasimba kupfuura mapfupa anodzima. Kazhinji anoshandiswa mumamiriro ezvinhu apo kusimba kwakanyanya uye kugadzikana kunodiwa, senge mukugadzika kwemaputsika mu diaphysis (shaft) yemapfupa marefu. Anoshandiswawo mune zvimwe zvishandiso zvekugadzirisa mukati nemaplate.
Muchidimbu, sarudzo pakati pemasikuruu ekubvisa tsvina neanoshanda zvinoenderana nerudzi rwepfupa riri kugadziriswa uye zvinodiwa chaizvo nemaitiro emapfupa. Masikuruu ekubvisa tsvina akakodzera mapfupa akapfava, ane maburi akawanda, nepo masikuruu ekubvisa tsvina akakodzera mapfupa akakora uye anotakura mutoro.
