Hip implant dik tak thlan dan .

Hip prosthesis hi implantable medical device a ni a, a hmun thum a awm a, chungte chu femoral stem, femoral head leh acetabular cup te an ni. Heng hmun pathumte hian hip joint chhia chu a thlak a, chu chuan mobility a siam tha a, damlo tan chuan natna tihdamna a ni.

01.A 2018-a component hrang hrangte chu engte nge ni . Hip Prosthesis 1000 a ni.?

Hip prosthesis hi a bulpui pathum a awm a, chungte chu:

A femoral stem .

Damlo femoral head an lakchhuah hnuah damlo femoral canal chu reamed a ni a, femoral stem chu dah a ni. Femoral stem hi damlo kum, morphology, ruh idiosyncrasies leh doctor-te tih dan azirin cemented emaw uncemented (press fit technique) emaw a ni thei.

Femoral lu .

Acetabular prosthesis (or cup prosthesis) .

Acetabulum chung lam atanga cartilage chhia, femoral head hlui awmna hmun chu lakchhuah a ni. A hmunah chuan tapered acetabular prosthesis a awm a. Screw emaw cement emaw hmangin a hmuna vawn theih a ni. He cup chhungah hian plastic, ceramic emaw metal inlay emaw a awm a, chu chuan prosthetic femoral head nen a inzawm ang.

02. Hip prosthesis atana hman tur thil pawimawh ber berte chu engte nge ni?

Hip prostheses te hi a siamna atana hman tur thil a zirin a danglam thei bawk. Tunah hian heng thilte hi chi thum-ah then theih a ni:

Metals te chu .

Metal thenkhat, stainless steel, cobalt-chromium alloy emaw titanium te hi femoral stem siam nan an hmang thin.

Friction pair tin hian ṭhatna leh ṭhat lohna an nei a, orthopedic surgeon chuan criteria engemaw zat hmangin friction combination tling ber a thlang ang a, chung zingah chuan damlo kum, taksa tihchakna leh ruh specificity te pawh a tel.

Metal prostheses hi a tlangpuiin a tha lo tih hriat a pawimawh hle. Chutiang implant siamtu company thenkhat chuan kum 2010-2011 khan hralh tawh loh an rel a, damlote hlawkna tur atan chuan hman loh implant te chu koh kir leh an rel a ni.

Hip joint-ah chuan heng particle te te hian allergic reaction a thlen thei a, chu chuan localized pain leh lesions a thlen thei a ni.

03 a ni . Hip prosthesis fixation dan ber chu engte nge ni?

Prostheses te hi femur emaw acetabulum emaw ah surgical cementing emaw secondary bone regeneration (uncemented emaw compression technique) emaw hmangin fix theih a ni. A tlangpuiin cemented femoral stem hi uncemented femoral cup nen a inzawm a ni. He technique hman dan tur hi a hnuaia mi ang hian tarlan a ni:

Surgical bone cementing technique hman a ni .

Bone cement hman chu . Acrylic polymer a ni a . Procedure chhung hian minute 15 chhungin a harh a, fixation hnuah a set nghal bawk.

Uncemented emaw press-fit emaw technique hman a ni .

Bone regeneration phenomenon avang hian uncemented prosthesis (prosthetic rods emaw cup emaw) chu kar ruk atanga kar sawm leh pahnih hnuah a ding reng thin. Bone regeneration tichak turin prosthesis chunglam chu hydroxyapatite layer te tak te, ruh mineral component hmanga khuh a ni tlangpui. Bone inhnaih tak chuan hydroxyapatite chu a component pakhat a nih thu a hre chiang a, chutah chuan rang takin prosthesis-a bony layer atang chuan a lo thang chhuak ta a ni. Hydroxyapatite hi chemical hmanga siam theih a ni.

04. Hip prosthesis hi eng chen nge a rei?

Tun hnaiah prosthesis-te service life a pung a: kum 50 hnuai lam damlote zingah kum sawm chhunga an la thawk thei zat chu 99% vel a ni.
