I-Hallux rigidus ivame ukuchazwa ngokuthi i-osteoarthritis yozwane olukhulu. Ilunga likazwane omkhulu liyagogeka futhi libe lukhuni ngenxa yokuwohloka koqwanga. Izindlela zokwelapha eziningana zingacatshangelwa.

Incazelo ye-hallux rigidus

Ku-anatomy, i-hallux ihambisana nozwane omkhulu. Lokhu kungaba nezinkinga ezihlukahlukene ezihlanganisa i-hallux rigidus ebonakala ngokuwohloka nokuqina kwelunga le-metatarsophalangeal lozwane olukhulu. Leli hlangano lixhumanisa ama-phalanges ne-metatarsus (isakhiwo samathambo esiphakathi nendawo yonyawo).

Ngaphambi kwe-hallux rigidus, kuvame ukuba ne-hallux limitus ebonakala ngokuncipha kokuhamba kwelunga le-metatarsophalangeal lozwane olukhulu.

Imbangela ye-hallux rigidus

Ngokuvamile sivame ukuchaza i-hallux rigidus njenge-osteoarthritis yozwane olukhulu ngoba ibangelwa ukuwohloka kwe-articular cartilage. Ukuguga nokwephuka koqwanga kubangela ukungqubuzana phakathi kwamathambo nokwakheka kwamathambo okubizwa ngokuthi ama-osteophyte noma “uqhwaku lukapholi”. Lokhu kukhula kuzokhubaza ilunga futhi kubangele ukungakhululeki nobuhlungu.

I-Diagnostic de l'rigid tow

I-Hallux rigidus, noma isifo samathambo sozwane olukhulu, kusoleka ukuhlolwa komtholampilo. Udokotela uphawula ukuwohloka, ukuqina nokuncipha kokuhamba kwelunga le-metatarsophalangeal lozwane olukhulu. Ukuqinisekisa ukuxilongwa, udokotela angase a-ode ukuhlolwa kwe-imaging yezokwelapha njenge-x-ray, i-MRI (i-magnetic resonance imaging), i-CT scan, noma i-scintigraphy.

Izici zobungozi ze-hallux rigidus

Njengezinye izinhlobo ze-osteoarthritis, lolo lozwane olukhulu lungathandwa izici eziningi. Isibonelo, kutholwe izici ezimbalwa zemishini ezingaholela ekwakhiweni kwe-hallux rigidus:

• micro-traumas ezingabangelwa ikakhulukazi umkhuba wemidlalo ethile efana nebhola likanobhutshuzwayo noma umdanso;
• ukucindezela okubangelwa uzwane olukhulu olude, njengoba kwenzeka ngonyawo lwaseGibhithe;
• egqoke izicathulo emincane noma izithende eziphakeme.

Ukulimala okuhlanganayo

I-Hallux rigidus iphumela ekuwohlokeni kwelunga le-metatarsophalangeal likazwane omkhulu okubangelwa ukwakheka kokukhula kwamathambo. Kukhona ukubonakala kwesigaxa kuzwane olukhulu, ezingeni lokuhlangana kwe-metatarsophalangeal.

Ukuqina okuhlangene

Ukukhubazeka kwamalunga kuhambisana nokuqina kwelunga. Ukuqina kuthanda ukwanda ngokuhamba kwesikhathi ngokulahleka okuphawulekayo noma okuphelele kokuhamba kokujoyina. 

Ubuhlungu bezinzwane ezinkulu

I-deformation ye-joint iphinde ibangele ukubonakala kobuhlungu ezwaneni elikhulu. Lokhu kungashuba kakhulu futhi kubangele ukungakhululeki okukhulu.

Uma kwenzeka i-hallux rigidus, ama-analgesics noma izidakamizwa ezilwa nokuvuvukala zingase zibekwe. Imijovo ye-intra-articular nayo ingasetshenziswa.

Kungase futhi kuhle uma kwenzeka i-hallux rigidus ijwayelane nezicathulo zakho futhi unciphise imisebenzi ethile engase igcizelele ukuwohloka kwelunga (isb. ibhola, umdanso, njll.).

Izindlela zokuhlinza

Uma ukwelashwa kwangaphambilini kungasebenzi, ukuhlinzwa kungase kuhlinzekwe. Amasu amaningana angacatshangelwa:

• i-metatarsophalangeal arthrodesis ehilela ukuvimbela ukujoyina;
• ukufakwa kwe-metatarsophalangeal prosthesis;
• i-osteotomy noma i-arthrolysis, ukuhlinzwa okuhlanganisa ukulungisa ukukhubazeka kwamathambo namalunga.

Ukuvimbela i-hallux rigidus kuhlanganisa ukukhawulela ngangokunokwenzeka ingcindezi kanye nama-micro-traumas kuzwane olukhulu. Ngalokhu, kunconywa kakhulu ukuthi ube nezicathulo ezanele futhi uzivumelanise nomsebenzi wakho.
