Cancellous Screw-a Anatomy leh Mechanical Properties te
Cancellous screw hi titanium emaw stainless steel emaw a siam a ni a, threaded shaft leh tapered tip a nei bawk. Shaft-a thread-te hian cancellous bone-ah lei ṭha tak a pe a, pull-out a veng a, tapered tip erawh chuan a chhehvel tissue tichhe lovin awlsam taka dah theihna a siam thung. Screw te hi ruh size leh fracture pattern hrang hrang awm theihna turin size leh sei hrang hrang a awm a. Cancellous screw-a mechanical property hi a material, diameter, a sei zawng leh thread design-ah a innghat a ni.

Cancellous Screw Fixation atana hmanraw hman dan
Cancellous screw fixation technique hi a specific indication leh fracture pattern ah a innghat a ni. Screw insertion chungchanga principle tlangpui chu:
Damlo awmna tur dik tak leh a ruh tliakna hmun hriat chian
Drill bit emaw tap emaw hmanga pilot hole siam
Screw sei zawng leh sei zawng tehna
Screwdriver emaw power drill emaw hmanga screw dah luh

Cancellous screw fixation hlawhtlinna tichhe thei thil pawimawh tak takte chu fracture fragment-te alignment dik tak, fracture tihtlem dan tur, screw dahna leh sei zawng dik tak, leh screw tensioning dik tak te hi a ni. Cancellous screw fixation avanga harsatna awm thei chu screw loosening, screw breakage, screw migration, non-union, malunion, infection, leh nerve emaw vessel injury te a ni.
Cancellous Screw Fixation atanga thil lo chhuak tur
Cancellous screw fixation atanga a chhuah dan chu a bik taka a lan dan leh damlo thil, kum, comorbidities, leh meizuk dinhmun te a innghat a ni. A tlangpuiin cancellous screw fixation hian fracture fragment te chu stability leh compression tha tak a pe a, chu chuan ruh a tidam rang a, a hnathawh dan pangngai a siam tha leh thin. Cancellous screw fixation hlawhtlinna rate hi 80% atanga 95% inkar a ni a, hei hi indication leh fracture pattern a zirin a ni. Cancellous screw fixation-a harsatna awmte hian a rah chhuah ha lo zawk a thlen thei a, chu chu dam tlai, non-union, leh natna rei tak a ni.
