Ukulimala kwamanxeba kufana nokunyuka kwamatye, okwenza ingqiqo inikwe ingqalelo ukunyamezela lo msebenzi ubeka kwiidijithi ngelixa uhamba ngokungafani kunye nokuxhasa ubunzima bomzimba wakho wonke. Nangona kunjalo, ukulimala okwenzekayo kunokuba ngumntu ongaqhelekanga, kungekhona nje ukutyunjwa komnwe okanye ukuchithwa kwamalungu.
Enye yeyona eyingozi engavamile eyenzekayo, kwaye ibonakala ngokukhawuleza ekukhuphukeni kwamatye, kuthiwa ukuphuka kwe-digital pulley.
Isizathu esenzayo sisiphumo sendlela yokukhangela amathoni kunye namanqaku kunye nesimo esithile apho iminwe ibanjwe ngexesha i-rock climbing.
Omnye umsebenzi wezemidlalo owenziwe ngolu hlobo kukulimala ngamapaki e-baseball. Imikhosi esebenza ngomnwe ibonakala ihluke kakhulu kule miba emibini, kodwa zombini ibeka uxinzelelo oluphezulu kumathambo eminwe.
Pulleys
Wonke umntu unesandla kwiminwe yakhe ebizwa ngokuthi iiplani zedijithali (oogqirha bavame ukusebenzisa amagama "inombolo" kunye "nomnwe" ngokungafaniyo). Ezi pulleyi zedijithali zizakhiwo ezizodwa ezibambe iintlobo zamathambo eminwe. Ngaphandle kwezi mpahla kwiminwe, ingxaki ebizwa ngokuba yi-tendoning tonson iya kwenzeka.
Iitendons zizakhiwo ezidibanisa imisipha kumathambo. Xa iimvumelwano zesikhumbuzo, iyakhupha i-tendon, leyo ikhupha ithambo. Kwiphepha elingaphezulu, iimisipha zontrakthi ye-forearm, ukudonsa i-flexor tendons zeminwe, eyenza iminwe yemvumelwano ibe yintonga.
Ngaphandle kwama-pulleys kwindawo ephethe iitoni phezu kwethambo, i-tendon yayiza kubambelela entendeni, ingasivumeli ukuba senze iqhosha. Lo msebenzi ufana nomsebenzi we-pulley we-crane ephakamisa into enzima.
Umnwe ngamnye unamapulane ayisibhozo, kodwa kubini nje kubo babini bavakalelwa kukuba kubaluleke kakhulu ekuthintela ukukhutshwa kwamathoni eminwe.
Xa umntu ephula i-pulley, angase aqhubeke neendlela ezahlukeneyo zokulimala ukusuka kwintlobo elula ye-pulley ukuphuka kwamapullethi amaninzi kwidijithi enye.
Kwiimeko ezibuhlungu kakhulu, xa iintambo zihamba, i-tendon ingasuka kumnwe xa yenza inkonti.
Uphawu lwePulley Rupture
Ukubonakaliswa kweempawu eziqhelekileyo zomnxeba kubandakanya:
- Ubuhlungu entendeni yesundu yomnwe kunye nokunyamezela ngcinezelo
- Ukuvuvuka komnwe
- Ubunzima obumba iqhosha
- Ukuva "i-pop" ngexesha lokulimala
Kubalulekile ukukrokra ukulimala kweplani yedijithali ehlolwe ngutitshala ngokukhawuleza (ezinsukwini ezimbalwa ukuya kwiveki) emva kokulimala. Nangona unyango olungxamisekileyo alufunanga, ukhatyelwa unyango (iiveki okanye iinyanga kamva) kunokukhokelela kwiziphumo ezingaphantsi. Imbakala ebaluleke kakhulu yokuvavanywa kwekliniki kukuqinisekisa ukuba kukho nayiphi na i-tendon ye-tendon ngenxa yokulimala kwe-pulley. Ukuba akunjalo, unyango luvame ukukhuseleka nje kulula ukude ukuvuvukala kunye nentlungu iyancedisa.
Ininzi ngokuqhelekileyo, umgca ophakathi okanye indekisi ngumunwe olimele. Ezi zibini ezibalulekileyo eminwe zonyulwe i-A2 kunye ne-A4 pulleys. Kwiindawo zokunyuka kwamatye, mhlawumbi okanye zombini loo maplale angalimala.
Ngokuqhelekileyo kwiipaki ze-baseball, ukulimala ku-A4 pulley.
Iimvavanyo ezizodwa zengqondo ziyakwenziwa kuzo zombini uncedo ngokuxilongwa nokucwangcisa unyango. I-x-ray inokukunceda ukuba ungabandakanyi ezinye izizathu zentlungu yomunwe kubandakanywa i- sprains kunye neziqhekeza zomnwe . Uvavanyo lwe- MRI luncedo, ngakumbi ukuba indawo okanye ubunzima bokulimala akucaci. Ngamanye amaxesha i-MRI iya kwenziwa ngomnwe oqhutywe ngqo, uze ulungele, ukubona ukuba kukho i-tendon.
Unyango
Ukuba kukho ukunyuka kwetoni, ukuphathwa ngokucokisekileyo kokulimala kufuneka kuvele.
Oku akusoloko kuthetha ukuba ukuhlinzwa kuyimfuneko, kodwa kukho izicwangciso ezikhethekileyo kunye neendlela zokwelapha ezingavumela ukuba iipleyi ziphilise kakuhle. Kuphela kwiimeko apho kukho ukuphuka kwamapayipi amaninzi okanye ukuba kukho unyango olunyanzelekileyo kufuneka ukuba unyango lube luyimfuneko.
Ngokufikela ekubuyiseni kwimisebenzi, oku kuyahluka ngokubaluleka kwintlungu. Ngohlobo lwe-pulley olunomdla, umsebenzi opheleleyo unokuphinda uqaliswe ngokukhawuleza xa ukuvuvukala kunye nentlungu sele ihlawule. Ukuphuka okupheleleyo okuphethwe ngokungagqirha, ubude bonyango buphakathi kweenyanga ezintathu. Kubantu abafuna ukulungiswa ngokutsha kokulimala kwe-pulley, kunokubakho ukuthintela ukufikelela unyaka ukususela ngexesha lotyando.
