Femoral neck fractures suav txog 50% ntawm pob txha pob txha. Rau cov neeg mob uas tsis yog cov neeg laus uas muaj pob txha femoral caj dab, kev kho mob sab hauv feem ntau pom zoo. Txawm li cas los xij, cov teeb meem tom qab kev phais, xws li kev tsis sib haum xeeb ntawm pob txha, femoral lub taub hau necrosis, thiab femoral caj dab luv luv, yog qhov tshwm sim hauv kev kho mob. Tam sim no, feem ntau kev tshawb fawb tsom mus rau yuav ua li cas los tiv thaiv femoral taub hau necrosis tom qab kho sab hauv ntawm femoral caj dab pob txha, thaum tsis tshua muaj kev saib xyuas rau qhov teeb meem ntawm femoral caj dab luv.

Tam sim no, txoj kev kho sab hauv rau femoral caj dab tawg, nrog rau kev siv peb lub cannulated screws, FNS (Femoral Neck System), thiab dynamic hip screws, txhua lub hom phiaj los tiv thaiv femoral caj dab varus thiab muab axial compression kom tsis txhob muaj kev tsis sib haum xeeb. Txawm li cas los xij, kev tswj tsis tau lossis ntau dhau zawv zawg compression inevitably ua rau femoral caj dab luv. Raws li qhov no, cov kws tshaj lij los ntawm Lub Tsev Kho Mob Thib Ob Kev Koom Tes nrog Fujian University of Traditional Suav Tshuaj, xav txog qhov tseem ceeb ntawm femoral caj dab ntev hauv kev kho mob pob txha thiab lub duav ua haujlwm, tau thov kom siv cov "anti-shortening screw" ua ke nrog FNS rau femoral caj dab tawg fixation. Txoj hauv kev no tau pom cov txiaj ntsig tau zoo, thiab kev tshawb fawb tau luam tawm nyob rau hauv qhov teeb meem tshiab ntawm phau ntawv Journal Orthopedic Surgery.
Tsab xov xwm hais txog ob hom "anti-shortening screws": ib qho yog tus qauv cannulated ntsia hlau thiab lwm tus ntsia hlau nrog ob txoj xov tsim. Tawm ntawm 53 tus neeg mob hauv pawg neeg tiv thaiv luv luv, tsuas yog 4 kis tau siv ob txoj hlua khi. Qhov no ua rau cov lus nug ntawm seb qhov ib nrab threaded cannulated ntsia hlau puas muaj qhov cuam tshuam los tiv thaiv luv luv.

Thaum ob qho tib si ib nrab threaded cannulated screws thiab dual-threaded screws tau soj ntsuam ua ke thiab muab piv rau cov tsoos FNS sab hauv fixation, cov txiaj ntsig tau pom tias qhov degree ntawm shortening nyob rau hauv lub anti-shortening ntsia hlau pawg yog ho qis dua nyob rau hauv ib txwm FNS pawg ntawm 1-hli, 3-hli, thiab 1-xyoo kev soj ntsuam cov ntsiab lus. Qhov no ua rau cov lus nug: Puas yog qhov cuam tshuam los ntawm tus qauv cannulated ntsia hlau lossis ob lub xov tooj ntawm tes?
Cov kab lus nthuav tawm 5 qhov xwm txheej uas cuam tshuam nrog kev tiv thaiv luv luv, thiab tom qab kev soj ntsuam ze dua, nws tuaj yeem pom tau tias nyob rau hauv rooj plaub 2 thiab 3, qhov twg ib nrab threaded cannulated screws tau siv, muaj qhov pom ntawm cov ntsia hlau retraction thiab luv luv (cov duab sau nrog tib tus lej sib haum rau tib rooj plaub).





Raws li cov ntaub ntawv dluab, qhov ua tau zoo ntawm ob-threaded ntsia hlau hauv kev tiv thaiv luv luv yog qhov pom tseeb heev. Raws li rau cannulated screws, tsab xov xwm tsis muab ib pawg sib piv rau lawv. Txawm li cas los xij, tsab xov xwm muab qhov kev xav tseem ceeb ntawm femoral caj dab sab hauv fixation, hais txog qhov tseem ceeb ntawm kev tuav femoral caj dab ntev.
