I-Q&A yoBugcisa yeeQela eziNxibelele zoKwakha kwakhona

Umbuzo: Ingaba imisonto ye-engile engalunganga ithintela njani i-screw back-out xa ithelekiswa nemisonto emcaba esemgangathweni?

A: Iflethi esemgangathweni okanye i-V-threads isebenzisa amandla e-radial yangaphandle ngokuchasene neendonga zangaphakathi zentloko ye-screw (i-tulip) xa iqinisiwe kwi-torque yokugqibela. Ngaphantsi koxinzelelo oluphezulu lwe-cyclic mechanical, lamandla eradial abangela ukuba iindonga ze-tulip zande kancinci okanye 'splay.' Nje ukuba i-splay yenzekile, intambo edibanisayo iyawa, ivumela isikrufu sokuseta ukuba siphume umva. Umsonto we-XC Medico we-negative-angle buttress buttress ubonisa ijiyometri ethambeka ezantsi nangaphakathi. Xa i-torque isetyenziswa, imikhosi yentambo itsala iindonga ze-tulip ngaphakathi, itshixa i-screw iseti ngokuqinileyo ngokuchasene nentonga kwaye ishenxise ngokupheleleyo ukusilela kokwakha okuqhutywa yi-splay.

Umbuzo: Kutheni inkqubo ye-cross-link inyanzelekile kwizilungiso ezingasemva kwecandelo elide ukuthintela ukutyibilika kwintonga?

A: Iintonga ezizimeleyo ezihambelanayo zixhomekeke kuphela kwi-friction grip yendawo ye-pedicle screws. Ukuba isigulana sinomgangatho wamathambo e-osteopenic, ukujikeleza kwe-trunk okuphindaphindayo kunokubangela ukuguqulwa kwe-microscopic yeentloko ze-screw, kuthobe isidima sokubamba ukukhuhlana kwendawo ngokuhamba kwexesha. Ukudibanisa i-addible cross-connectors bridges the left and right rods kwi-rigid quadrangular box frame. Olu qhagamshelo luziiplana ezininzi ludlulisela uxinizelelo lwe-chear kulo lonke ulwakhiwo, nto leyo eyenza intonga ezimeleyo etyibilikayo ingakwazi ukutyibilika ngoomatshini nokuba isiphambuka esinye sivalelwa ukunxitywa kwe-micro-fretting.
