Tshuaj loog: Tus neeg mob tau muab tso rau hauv cov tshuaj loog lossis tshuaj loog hauv cheeb tsam, nyob ntawm tus kws phais qhov kev nyiam.
Incision: Tus kws phais ua ib qho kev txiav tawm ntawm qhov chaw tawg kom nkag mus rau cov pob txha.
Kev npaj ntawm cov pob txha: Cov pob txha tawg yog realigned thiab npaj rau fixation.
Ntxig ntawm cov ntsia hlau: Cov ntsia hlau tshem tawm ib nrab ntawm cov xov yog muab tso rau hauv cov pob txha siv lub hau ntswj lossis laum. Qhov tsis muaj xov ntawm cov ntsia hlau yog muab tso rau hauv nruab nrab ntawm cov pob txha tawg, thaum lub threaded feem yog screwed rau hauv cov pob txha. Cov ntsia hlau yog nruj rau qhov tsim nyog torque.
Kaw: Qhov kev txiav yog kaw nrog sutures los yog staples.
Risks thiab Complications
