Ukucindezelwa kwemizwa kuyisifo esivamile se-thumb numbness
Ubumbulu nokukhipha izinkinga yizinkinga ezivamile, futhi ukuhlinzekwa kwamagciwane kwesithupha nesandla kuyinkimbinkimbi. Uma uzizwa unomunwe wesithupha noma isandla sakho, ukucindezeleka kwemizwa kuyimbangela enkulu. Nakuba kungavamile, kubalulekile ukwazi ukuthi imbangela iyingozi. Ukuziphazamisa izandla kungabonisa izinkinga ezinkulu ezinjenge- stroke , noma ngisho nokuhlaselwa yinhliziyo noma i- aortic dissection .
Kodwa-ke, ukunganaki ngokuvamile kuhlotshaniswa nezinye izimpawu kulezi zimo. Ubumbulu kufanele buhlolwe ngokushesha uma kungenzeka ngokuza ngokuzumayo, kuhambisane nezinye izinkinga ezinjengobuthakathaka, azikho isizathu esizwakalayo (njengokulala embongeni), noma kuhlotshaniswa nentuthuko yentamo noma isifuba.
Yikuphi okushiwo yi-Numb empeleni
Kunezinkinga ezimbili ezithandwayo: incazelo yegama elithi numbness kanye nezingxenye zesandla esinesisindo esingavamile. Nge-numbness, ingabe usho ukuthi "izikhonkwane nezinaliti" umuzwa, owaziwa ngokuthi i- paresthesia , noma usho ukungabi nomuzwa okuphelele? Uma ucabanga ngesithupha sakho, yonke indawo yesithupha ishintshwe ngokufanayo, noma ingabe ingaphambili, eceleni, noma emuva kwesithupha? Umbuzo wokugcina ungabaluleka kakhulu ekusizeni ukuhlukanisa imbangela yaman numbness.
Ukuqonda iMidiya yaseMedian
Isandla sithola ukuhlinzekwa kwayo kwamagundane okuphuma emathanjeni avela phakathi kwamathambo entanyeni.
La magatsha aphikisana futhi avuleke ngaphakathi kwe-plexus eyinkimbinkimbi, bese eba nemizwa ebizwa kahle ngokuthi i-median, radial, ne-ulnar. Ngenkathi zonke izinzwa ezintathu zihilelekile ekuthumeni isithupha, kuphela izinzwa zomsakazo kanye nomphakathi zihilelekile ukuzwa kwesithupha.
I-nerve median inikeza inzwa kulokho okubizwa ngokuthi "isundu" ingxenye yesithupha-okuyingxenye nge-thumbprint kanye nengxenye efihlekile uma wenza inkinobho.
Le nerve iphinde inikeze ubuso bomnweba wenkomba kanye neminwe ephakathi.
I-nerve median ivame ukuchotshozwa, okwenza kube namandla okunciphisa ukuthwala izimpawu zikagesi emuva esikhumbeni kuya emgodini womgogodla nobuchopho. Umphumela uba ukungafihli. Ngezinye izikhathi, ubuthakathaka bungabangela, ikakhulukazi emisipha egoqa isithupha kumunwe omncane.
Indawo evamile kakhulu ye-nerve median ukuba ikhonjiwe emgodini we- carpal , umgudu omncane esihlalweni lapho izinzwa zomphakathi zihamba ngezintambo eziningana eminwe. Uma i-tendon ivuvuka, ukuvuvukala emgodini omncane kungabangela inzwa ekhonjiwe. Lokhu ngezinye izikhathi kuyabuhlungu, kodwa hhayi njalo.
I-nerve median ingabuye ikhonjiwe endaweni ethile endaweni ethile engalweni, kodwa ngokuvamile lokhu kubangele ukuphazamiseka noma ubuthakathaka engalweni noma esihlalweni kanye nesandla nesithupha.
Ukuqonda i-Radial Nerve
Igatsha elingenalutho lomswakama womswakama libhekene nokuletha inzwa kusuka ngemuva kwesandla, isithupha, neminwe yokuqala yokuqala ebuchosheni. Uma umswakama we-radial uphazanyiswa, ukungapheli komhlane kungase kuholele.
Ukulimala emndenini we-radial akuyona into ejwayelekile kune-nerve medial. Ukuhlukunyezwa kubonakala futhi, nakakhulu.
Esikhundleni sokuvuvukala okucashile okubamba isisindo, imbangela ingase ibe ukuphuka kwethambo esandleni, isibonelo.
Ngaphezu kwalokho, ngaphandle uma umonakalo ungena egatsheni elingenasici, cishe kuyoba nobukhulu obuthakathaka obunzima bokuqina. Esikhathini sesithupha, lokhu kubonakala kakhulu emisipha edonsa isithupha kude nomunwe wokuqala, njengokungathi ulingisa isando esibiziwe sesibhamu.
Ukuqonda i-Ulnar Nerve
Ukulimala emlonyeni we-ulnar njengoba uhamba ukusuka entanyeni yakho kuya phansi kuya eminwe yakho kungabangela ukuphazamiseka nokumboza eceleni kwesandla sakho, ikakhulukazi umunwe wakho nomunwe omncane. Isibonelo esisodwa uma ufaka "ithambo lakho elimnandi" futhi uzizwe ungadonsa ukudubula phansi kweminwe yakho.
Njengezinzwa zomphakathi, i-ulnar nerve ingakwazi ukuchotshozwa, ikakhulukazi njengoba idlula ngaphansi kwesigqoko. Uma lokhu kwenzeka, umuntu udala umthamo wokubeletha womzimba , ongabangela ukuphazamiseka nokumboza emgqeni nasomunwe omncane, kanye nokubuthakathaka kwesisindo esandleni.
Ukuqonda I-Spinal Cord, i-Nerve Roots, ne-Brachial Plexus
Izinzwa zigijima ukusuka esandleni kuze kube yingalo, bese zifika emthonjeni womgogodla. Njengemigwaqo esondela edolobheni elikhulu, ithrafikhi eningi (kulokhu lwazi lwazi kagesi) liyakwazi ukusondela lapho usondela khona phakathi kwesenzo-ubuchopho. Amagundane ayekade ehluke ngokuphelele aqala ukugijima eceleni, ekugcineni aguqulwe ebuchosheni be-brainstem, indawo engekho enkulu kunazo zonke kunezithupha zakho, lapho ugeleza yonke imininingwane phakathi komzimba nobuchopho.
Ngenxa yalesi sizathu, osondelene nenkinga ebuchosheni, cishe kungenzeka ukuthi ukugeleza kolunye ulwazi kuzophazanyiswa, njengezimoto ezihamba ngebhayisikili.
Ngaphambi kokungena emgwaqweni ongasemthethweni wezintambo zomgogodla, ulwazi lwegesi luhamba ngokuhamba ngendlela eqondile kakhulu eyaziwa ngokuthi i-plexus ye-brachial. Nakuba kungenzeka ukuthi lesi sifo esincane kakhulu lapha singabangela ukuphazamiseka kwesithupha esisodwa nje, akunakwenzeka, futhi ngokujwayelekile kuba yinto encane kakhulu uma ulwazi lungafika emthonjeni womgogodla. Ezinye izingxenye zomzimba zazingenakulinganiswa nje kuphela, kodwa ubukhulu buthakathaka bungaba khona.
Kufanelekile ukubalula okuhlukile kokulawula. Ulwazi olunembile nolwazi lwezimoto luhlukaniswa emthonjeni womgogodla, kusukela lapho izimpande zemizwa zingena khona. Ulwazi lwezimoto lufaka ulwazi lwangaphambili nolwazi olusensimini ngemuva komgogodla. Ngenxa yalesi sizathu, kungenzeka ukuthi ube nomkhuhlane owodwa kuphela ovela kulesi chungechunge. Noma kunjalo, lokho kuphazamiseka kungase kuthinte iphesenti ephakeme yomzimba.
Izivivinyo Zokuhlola Ukulinganisa Nokulinganisa
Izivivinyo eziyalwe zivame ukuqondiswa ekutholeni imbangela eqondile yokuguga nokugubha, ngenhloso yokuthola uhlelo oluhle lokuphulukisa. Akufanele ulindele ukuba nazo zonke lezi zivivinyo, kodwa kuphela ezimbalwa ezikhethiwe okungenzeka ziwusizo esimweni sakho ngasinye.
- I-Electromyography (EMG) noma isifundo se-nerv conduction (NCV) : Lezi zivivinyo zihlola umsebenzi wezinzwa ezandleni nasemilenzeni. I-EMG iyivivinyo elibandakanya ukusebenzisa izinaliti emisipha ethintekile, kuyilapho i-NCV ihilela ukusebenzisa ama-electrodes esikhumbeni bese usebenzisa umphumela omncane wokushona. Zombili lezi zivivinyo azithokozi kahle ngemizuzwana embalwa, kepha abantu abaningi bayakwazi ukubekezelela ukuhlolwa ngaphandle kokuthola ubunzima, futhi akufanele kube khona ubuhlungu noma ubunzima obusele ngemuva kokuhlolwa kokuhlolwa.
- Kungase kudingeke ube nesichungechunge se- CT noma ubuchopho be-MRI uma kungenzeka ukuthi ukuphazamiseka noma ukugubha kubangelwa ukushaywa, isifo sobuningi, isifo sofuba, isifo sobuchopho, noma esinye isimo sezokwelapha esibandakanya ubuchopho.
- Ukukhishwa kwesibindi kungadingeka ezimweni ezingavamile, njengokuthi udokotela wakho ukhathazekile ngesifo esibi kakhulu esibizwa ngokuthi i- Guillain-Barre Syndrome (GBS). I-GBS ibonakala ubuthakathaka obunzima bemilenze, ilandelwa ukubuthakathaka kwesandla nokubuthakathaka kwemisipha yomzimba, kuhlanganise nemisipha elawula ukuphefumula. I-GBS ivame ukuqala nge-numb numbness noma ukugoqa kwezinyawo noma izandla.
Njengoba ubuthi, ukungabi nokudla okunomsoco, kanye nezinye izifo zingalimaza izinzwa zomzimba, udokotela wakho angase alawule ukuhlolwa kwegazi. Noma kunjalo, lezi zimo zivame ukuthinta umzimba wonke ngesikhathi esisodwa, ngakho kungaba okungavamile ukuba uhlangothi olulodwa lomzimba lungathinteka ngaphezu kwesinye.
Izibonelo zihlanganisa ukudoba okuholela ekutheni ubhekene nobunzima be- vitamin B12. Isifo sikashukela nesifo se-thyroid singabangela neuropathy ye-peripheral.
Izwi elivela
Esikhathini esiningi, isikhubekiso sesithupha sinemiphumela nje yokucindezelwa kwesibindi somzimba. Nakuba ecasulayo, akuyona eyingozi, akunikezi ezinye izimpawu zokuxwayisa ezikhona. Uma nje ubuchopho buyiyona nkinga kuphela, akukho ukwelashwa okunonya okwenziwe ngokujwayelekile. Ngisho noma ngenxa yesifo, odokotela bangase banganiki imithi ngaphandle kokuba kunezinye izimpawu ezinzima ezikhona. Igazi elinamandla elinamandla linganikezwa ngesifo sohlangothi, kodwa lokhu kwandisa ingozi yokuphaphaza ebuchosheni, ngakho-ke isetshenziswa ngokuhlakanipha.
Uma ukungenwa kwesinye isithupha noma iminwe yakho kuqhubekela phambili, kuwumqondo omuhle ukuvakashela udokotela wakho ukuze uhlole, kodwa ngaphandle kokuba ezinye izimpawu zobuthakathaka noma ukuvela kungazelelwe zikhona, cishe akunzima ukuphuthumayo.
