Kutholakala enhliziyweni yebhande le-pelvic, amalunga we-sacroiliac ahlanganisa amathambo we-pelvic ngapha nangapha nomgogodla. Amalunga abalulekile phakathi komzimba ongezansi naphezulu, angaba yisihlalo sobuhlungu.

Amalunga we-sacroiliac, noma amalunga we-SI, abhekisa emajoyini amabili axhumanisa i-ilium os ku-pelvis ne-sacrum yomgogodla. Kutholakale ngokujulile, ezansi komgogodla kwesokudla nangakwesobunxele se-sacrum, ngandlela thile ibhuloho elixhumanisa umgogodla namathambo emilenze.

Kuyinto yokuhlangana kohlobo lwe-synovial: ine-capsule ye-articular equkethe uketshezi. Isakhiwo saso siyashintsha ngeminyaka: i-capsule ehlangene ithuthukiswe kahle ezinganeni, bese iyaqina futhi ibe yi-fibrosis eminyakeni edlule. Ngakolunye uhlangothi, uqwanga olumboza indawo esezingeni eliphansi luyancipha futhi lucishe lunyamalale ngemuva kweminyaka engama-70.

Ilunga ngalinye lizungezwe futhi laqiniswa inethiwekhi eyinkimbinkimbi yemisipha yangaphakathi ngaphambili, imigudu ye-ventral, futhi ngemuva, imigqa ye-dorsal (umgogodla ongaphezulu, i-iliotranverse ligaments, i-ilio-transverse sacral ligament, noma i-iliosacral, i-ligament interosseous), kanye okwangaphandle. Ekugcineni, ilunga ngalinye le-SI lixhunywe emaqenjini anamandla emisipha kufaka phakathi imisipha (ubuso obungemva kwethanga), i-psoas (ubuso bangaphambili besinqe), ibhande le-iliotibial (ubuso bethanga langemuva), i-piriformis (i-buttock) kanye i-rectus femoris (isici sangaphakathi sethanga).

I-pivot yangempela emaphakathi, amalunga we-sacroiliac asabalalisa isisindo somzimba phakathi kwaphezulu nangaphansi futhi adlala indima yokuxhasa umgogodla.

Amajoyini we-SI angenza ukunyakaza okuyinkimbinkimbi kwe-nutation kanye ne-counter-nutation, ikakhulukazi ngokuya ngokuhamba kwe-coccyx, lapho kuguqa phambili noma kuthwalwa umthwalo, ngokwesibonelo, kepha lokhu kuhamba kuhamba ngesilinganiso esiphansi. Amalungu amabili e-SI ancikene: ukunyakaza ohlangothini olulodwa kubangela ukunyakaza kolunye. Ukuhamba kwabo futhi kuncike kokunye okuhlanganisiwe kokhiye okhalweni: i-pubic symphysis.

Ukuguqulwa

Ijoyini elicindezeleke kakhulu nsuku zonke, ilunga le-SI liyindawo ejwayelekile kakhulu ye-osteoarthritis.

Isifo se-Sacroiliac

I-Sacroiliac joint syndrome, noma i-sacroiliac syndrome, ibhekisa esimweni esibuhlungu semishini. Kubonakala sengathi ubuhlungu buvame ohlangothini olulodwa emhlane ongezansi, ezinqeni, emgodini ngisho nasethangeni, kunzima ukuhlala. Ngakho-ke kuvame ukuphutha ngenkinga ye-lumbar noma i-sciatica.

Izici ezahlukahlukene zingaba umsuka wale syndrome:

• ukungalingani kwezitho ezingezansi;
• i-hyperlodosis (ukugoqa ngokweqile emuva);
• ukuwa ezinqeni;
• ukunyakaza okuphindaphindayo okubandakanya isifunda se-lumbar kanye ne-pelvis;
• ukubeletha okunzima;
• i-lumbar sprain;
• umzamo owedlulele;
• ukusebenza isikhathi eside ukuqhosha ezinqeni.

Isifo sokuvuvukala

Amalunga we-SI ajwayele ukuba ngowokuqala ukuthinteka ku-ankylosing spondyloarthritis, isifo esingamahlalakhona sokuvuvukala kwamathambo. Lokhu kubonakala ngobuhlungu ezinqeni ezibizwa nge- “rocking”, ngoba kwesinye isikhathi kuthinta izinqa ezifanele, kwesinye isikhathi kwesobunxele.

Ijoyini le-SI futhi liyindawo ejwayelekile kakhulu kwezinye izifo ezivuthayo ze-spondyloarthropathies, ngisho nezifo ezithathelwanayo ezingavamile eziqoqwe ngaphansi kwegama elithi seronegative spondylitis: i-ankylosing spondylitis, i-spondylitis ehambisana ne-psoriasis, i-Reiter's syndrome, izifo ezithile zokuvuvukala zomgudu wokugaya ukudla.

I-sacroiliac syndrome ingaphathwa yi-physiotherapy, i-chiropractic. 

Ukwelashwa kwe-spondyloarthritis kuhlose ukunqanda ubuhlungu, ukuqhubeka kwesifo nokuvimbela ukuqala kwe-ankylosis. Lokhu kusekelwa kwenziwa ngemikhakha ehlukahlukene, nge:

• imishanguzo ye-analgesic ne-anti-inflammatory yokuqeda izimpawu:
• Ama-DMARD okwelapha lesi sifo;
• ukwelashwa kwendawo kwamalunga abuhlungu;
• ukuvuselelwa okusebenzayo.

Ukuhlolwa komtholampilo

Kubandakanya ukushaya kwenhliziyo kanye nokuhamba okuthile nokuhlolwa okusetshenziselwa ukuhlola ukusebenza kwejoyinti: ukuqhutshwa kathathu, ukusatshalaliswa kokuqondiswa kwamaphiko e-iliac, ukuqondisa kweGaensen, njll. kungenzeka ukuhlukanisa i-sacroiliac syndrome kwizinkinga ze-lumbosaciatric. Udokotela kufanele futhi ahlole ukungabi bikho kwezimpawu zesistimu (umkhuhlane, ukukhwehlela, ukukhathala, njll.) Okungahambisana nesifo samathambo.

Izivivinyo ze-Medical imaging

I-Radiography ye-pelvis ne-sacroiliacs ukuhlolwa komugqa wokuqala. 

I-MRI yama-sacroiliacs iyayivumela ukuthi ihlole kusenesikhathi isifo esithathelwanayo noma esivuthayo. Kuyasiza kakhulu ekutholeni i-spondyloarthritis. Izithombe zizobe zikhombisa ukuguguleka.
