Imisebenzi yeLumbar Spine

1 -

Ngaphantsi

Umqolo ophantsi uyingxenye yomqolo wamagxa oqulethe umlenze we- lumbar , i- sacrum kunye ne- coccyx .

I-Lumbar Vertebrae kunye noLungelelaniso olufanelekileyo.

Kwimeko eqhelekileyo, umphefumlo onomsoco, i-vertebrae i-lumbar igxininise phezulu komnye kwelinye ilungelelaniso.

Ngelixa onke ama-vertebrae anesimo esifanayo, amathambo e-lumbar awona mkhulu. Kungenxa yokuba baphethe (umkhulu) umthwalo osasazwa ukusuka phezulu kwintloko ukuya emncintisini ophantsi.

Esinye isizathu sokuba amathambo angama-lumbar aphezulu kunamazwi omlomo wesibeleko kunye ne- thoracic vertebrae kukuba kufuneka abe mkhulu kwaye anamandla ukuxhasa imisipha namathambo ngexesha lokuhamba. Indawo engummango womgudu ngumzimba wenyama. Le ndawo yimbatho yezinto ezininzi ezisisiseko, kubandakanywa ibhalansi kunye nokuveliswa kwemveliso (ukuhamba nokusebenza, njl.) Iimfuno ezikwindawo ye-lumbar zikhulu.

I-Vertebral Body ye-Lumbar Vertebra

I-front vertebra i-lumbar ifana ne-disk ejikelezileyo idiski. Ngaphezulu nangaphantsi kwe-vertebra nganye i -disk intervertebral .

I-vertebrae ye-lumbar ithatha umthwalo wehla emthonjeni, ngaloo ndlela ixhasa ubunzima bomzimba.

Umva weLumbar Vertebra

Umqolo we-vertebra unzima kakhulu, ngokukhupha kunye neendlambo, nganye inenjongo ehambelana nomgudu. Ithambo lisuka kumva we-vertebra ukwenza imijelo yamanzi, amanxeba okuzinza, kunye neendawo zokuncedisa izihlunu. Nalu uluhlu:

• Inkqubo yezintlu
• Inkqubo ejikelezayo
• Idibeneyo
• ULamina
• Pedicle
• Pars interarticularis

ILumbar Curve

Ummandla ngamnye womgudu unomlenze ohambelana nawo. I-curve evamile ye-lumbar spine yi- lordosis .

6 -

I-Lumbosacral Joint okanye i-L5-S1

I-lumbar spine ihlala kwi- sacrum . Indawo apho badibana khona kuthiwa i-lumbosacral joint, okanye i- L5 -S1.

Ikhonkco le-L5-S1 yilapho kwenzeka khona i-spondylolisthesis yokulimala.

Isigubhu

I- sacrum iyithambo elithabathekileyo elincinci elingaphantsi kwe-lumbar spine. Isebenza njengomda phakathi kwama-hip 2 athile ngapha nangapha, ukuzinzisa yonke indawo ye-pelvic. Iimbilini ezininzi ziphuma emingxeni kwicala ngalinye le-sacrum, kubandakanywa nesibindi se-sciatic, eyona nto ibangela iintlungu zabantu abane-sciatica.

Umjikelezo womgceni uphenduka kwi-sacrum. I-curral curve yi- kyphosis .

Coccyx

Ngaphantsi kwe-sacrum ithambo le- coccyx .
