InterTAN Intramedullary msomali

Intertrochanteric hip fractures ndizofala komanso zovulaza zowononga makamaka kwa okalamba.Trochanteric fractures (TF) ndi yachiwiri yophulika kwambiri ya proximal femur pambuyo pa kusweka kwa khosi lachikazi ndipo ndizomwe zimayambitsa matenda ndi imfa mwa anthu okalamba masiku ano.

Pofika chaka cha 2050, chiwerengero cha pachaka cha anthu othyoka ntchafu padziko lonse lapansi chikuyembekezeka kupitirira 6.3 miliyoni chifukwa cha ukalamba wa mayiko ambiri a kumadzulo.Ku USA kokha, chiwerengero cha ziwombankhanga za m'chiuno chikuyembekezeka kuwonjezeka kuchokera ku 320,000 pachaka kufika ku 580,000 ndi 2040. Kufuna kowonjezereka kumeneku kumayambitsa mavuto aakulu kwa ntchito yaumoyo ponena za ogwira ntchito ndi zothandizira zomwe zimayenera kuyang'anira odwalawa.Ku USA, ndalama zothandizira zaumoyo za kayendetsedwe ka fractures za m'chiuno zikuyembekezeka kupitirira $ 10 biliyoni pachaka, pamene zotsatira za ntchito yaumoyo ku UK zikuyembekezeka kukhala $ 2 biliyoni pachaka.Ndalamazi zimayendetsedwa osati kokha ndi ndalama za opaleshoni yoopsa komanso chisamaliro chapambuyo, kuphatikizapo kukonzanso.Ngakhale kuti opaleshoni yothyoka m'chiuno imakhala yothandiza kwambiri, odwala amatha kudwala kwambiri chifukwa cha ululu, kusamva bwino komanso kuyenda kochepa panthawi yomwe akuchira ndipo nthawi zambiri sangakwanitse kukwaniritsa ntchito zomwe zisanachitike.Kafukufuku akuwonetsanso kuti pali mgwirizano pakati pa kuthyoka kwa m'chiuno ndi kuchuluka kwa anthu omwe amafa ndi 30% kuposa omwe amafa kuposa omwe ali ndi zaka zakubadwa komanso osathyoka m'chiuno.Komabe, kusamala kumayenera kutengedwa potanthauzira zomwe zanenedwazo, chifukwa anthu omwe amathyoka m'chiuno amatha kukhala osalimba kwambiri komanso amatha kudwala.

Padziko lonse lapansi, chiwopsezo cha kusweka kwa proximal femur chikuchulukirachulukira chifukwa cha kusintha kwa anthu komwe kumapangitsa kuti anthu azikhala ndi moyo wautali.

Chithandizo cha opaleshoni ndi njira yabwino kwambiri yothetsera fractures ya intertrochanteric chifukwa imalola kukonzanso koyambirira ndi kuchira kwa ntchito.

Pofuna kuchepetsa zovuta zowonongeka kwa nthawi yayitali, njira zothandizira panthawi yake zomwe zimapereka kukhazikika kwabwino kwa fracture ndi kulimbikitsana koyambirira kwa odwala kwakhala njira yabwino yothetsera fractures izi.Kamodzi dynamic hip screw (DHS) internal fixation ndi imodzi mwazosankha zazikulu, koma sizichita bwino ndi kuchuluka kwa kulephera kwa mkati kwa TF yosakhazikika.Kuonjezera apo, opaleshoniyi ingapangitse kutaya magazi kwambiri, kuwonongeka kwa minofu yofewa, komanso kuwonjezereka kwa matenda omwe alipo mwa odwala okalamba.Chifukwa chake, zida za intramedullary fixation zatchuka kwambiri chifukwa chaubwino wa biomechanical pochiza TF yosakhazikika poyerekeza ndi kukonza kwamkati kwa DHS.

Intertan Nail yogwiritsa ntchito 2 cephalocervical screws mumakina ophatikizika, ikuwonetsa kukhazikika komanso kukana kusinthasintha kwa mutu wa chikazi ndi intramedullary poyerekezera ndi machitidwe achikhalidwe a intramedullary.Kafukufuku wa biomechanical adawonetsa kuti Intertan Nail ili ndi mapindu ochulukirapo a biomechanical pakukonza mkati mwa fractures yosakhazikika poyerekeza ndi njira yachikhalidwe ya intramedullary misomali ya Intertan Nail.Kafukufuku wina adanena kuti opaleshoniyi inali ndi zotsatira zabwino zachipatala komanso zovuta zochepa].Kafukufuku wa biomechanical wa Nüchtern et al.adawonetsa kuti Intertan Nail imakwaniritsa kukhazikika kwambiri ndi nsonga yapamwamba kwambiri komanso kupirira katundu wapamwamba.
