I-Syme prosthesis, eyaziwa ngokuba yi-ankle prosthesis, isetyenziswa kakhulu emva kokunqunyulwa kwe-Syme, kwaye kwiimeko zomntu ngamnye, inokusetyenziswa emva kokunqunyulwa kwe-trans-foot kunye ne-ankle efana nokunqunyulwa kwe-Pirogov.Iprosthesis ye-Syme inokuthathwa njengeprosthesis ekhethekileyo yethole elifanelekileyo lokunqunyulwa kweqatha.
I-Syme amputation ngoku isetyenziswa ngokuqhelekileyo ukunqunyulwa kweenyawo kunye neqatha.Ngenxa yokuba incam ye-tibia kunye ne-fibula ishiywe emva kokuqhawulwa kwe-ankle, iziphelo azikwazi ukuthwala ubunzima, ngoko ke akukho phantse ukunqunyulwa kwe-ankle ukunqunyulwa kwe-ankle.Ngaphambili, kwathiwa olu hlobo lweprosthesis lubizwa ngokuthi "i-ankle cuted prosthesis", ngokucacileyo kungenangqiqo.
Ukongeza, ukunqunyulwa kwePirogov okuxhaphakileyo, ukunqunyulwa kweBoyd kunye nokunqunyulwa kwelungu leChoppart azifane zisetyenziswe ngenxa yokuguqulwa konyawo rhoqo, ukonakala kwesikhumba, ukuthwala isiphelo esibi kunye nezinye izinto..
Iprosthesis ye-Syme inokuthwala ubunzima bokuphela kwelungu elishiyekileyo kwaye inomsebenzi omhle wokuhlawulela.Ngaphambili, indlela yemveli yokwenza iSym prostheses yayikukusebenzisa ngesikhumba ukwenza i-socket slot, kunye nokongeza iintsimbi zentsimbi ukomeleza okuthile.
Ngoku, iprosthesis yeSym isebenzisa i-resin composite material vacuum vacuum ukwenza isokhethi epheleleyo yoqhagamshelwano, ephucula kakhulu inkangeleko kunye nomsebenzi weprosthesis.
I-Syme amputation yi-supracondylar amputation ye-distal end ye-tibia kunye ne-fibula.Iimpawu zeSyme prosthesis ziquka:
1. Ngenxa yokuba ilungu elishiyekileyo lide kakhulu, akukho ndawo yokufakela i-ankle joint, kunye ne-static ankle (SACH) unyawo lusetyenziswa ngokubanzi;
2. Ngenxa yokuba isiphelo selungu eliseleyo lihlala li-bulbous, elikhulu kuneqela, unyango olukhethekileyo (njengokuvula ifestile) lufunekayo xa usenza i-cavity yokufumana uqhagamshelwano olupheleleyo, kwaye ukubonakala akukuhle kakhulu;
3. Ilungu elishiyekileyo lide, izihlunu zethole ziphelele ngokulinganayo, kwaye kukho ingalo ye-lever ende, kunye nelungu elishiyekileyo linomphumo omhle kwi-prosthesis;
4. Isiphelo selungu elishiyekileyo sinobunzima.Xa kuthelekiswa ne-prosthesis yethole, isiphelo somlenze oseleyo unobunzima obuninzi kune-patellar ligament, ehambelana ngakumbi neempawu ze-physiological zomzimba womntu;
Ukuze kufezekiswe injongo yokunxiba kunye nokukhulula, ukunqunyanyiswa okusebenzayo, kunye nokuphuculwa kwenkangeleko, uhlobo lokufumana i-Syme prosthesis luhlala luvela, kwaye ngoku ezi ntlobo zilandelayo zenziwa ikakhulu.
(1) I-Sym prosthesis ngokuvula kwangaphakathi: i-cavity efunyenweyo yenziwe ngezinto ze-resin, kwaye i-prosthesis ye-SACH ikhethiwe, kwaye ifestile ivuliwe kwicala langaphakathi.
(2) I-Syme prosthesis enecala elingasemva lokuvuleka: into efanayo nangasentla, kodwa inefestile ngasemva.
(3) Umaleko ophindwe kabini wokufumana umngxuma we-Syme prosthesis: Umngxuma ongaphakathi owamkelayo sisigqubuthelo selungu elishiyekileyo elenziwe ngezinto ezithambileyo.Emva kokwenziwa kwevacuum, iindawo ezingaphandle kufuneka zizaliswe kwaye zilinganiswe, kwaye emva koko kwenziwa i-vacuum lamination kunye nomphandle wokwamkela umphandle.Iprosthesis yomelele, kodwa imilo yomelele kakhulu.
⑷ Inxalenye yodonga oluthambileyo lwe-Syme prosthesis: Udonga lwe-receptacle phezulu nasemva kwe-ankle lwenziwe nge-resin ethambileyo, e-elastic kwaye ayifuni ukuvula ifestile, ephucula ukubonakala kweprosthesis.
