Ingxenye ye-Spine Especially Intsha Yokulimala
I-L5-S1 yigama elisetshenziselwa ukuchaza isigaba somgogodla oqukethe i-vertebra yokugcina engemuva ongemuva (okuthiwa i-L5) kanye namathambo afane nantathu esheshayo ngokushesha ngaphansi kwalo owaziwa yi-sacrum. I-sacrum yenziwe ngamathambo amahlanu lapho iS1 iphezulu khona.
Ungacabanga nge-L5-S1 njengendawo ecacile lapho isikhala semilenze siphelela khona futhi isikhala se-sacral siqala. Isihlanganisi esibaxhumanisa sibizwa ngokuthi ukuhlanganiswa kwe-lumbosacral.

Isakhiwo se-Lumbar Spine neSigrumUmgogodla womuntu unamathambo angu-33 angama-24 kuphela ahamba ngayo ngokugcwele. Zidilizwa zibe yizigaba kusukela phezulu kuya komsila, kanje:
- Umgogodla (intamo) ngamathambo ayisikhombisa ukusuka ku-C1 kuya ku-C7
- I-thoracic spine (emkhatsini we-back) ne-bone elisuka ku-T1 kuya ku-T12
- I-Lumbar spine (ephansi emuva) ngamathambo amahlanu ukusuka kuL1 kuya ku-L5
- I-sacrum ene amathambo amahlanu ukusuka ku-S1 kuya ku-S5
- Isizinda se-coccyx (tailbone) ngamathambo amane ukusuka ku-Co1 kuya ku-Co4
Ngenkathi abantu abaningi bevame ukucabanga nge- sacrum njengethambo elilodwa, empeleni liqukethe amathambo amahlanu athile aqala ukufiphaza ngokushesha ngemva kokuzalwa futhi aqhubeke enza kanjalo aze ahlukunyezwe ngokuphelele uneminyaka engama-30.
Okufanayo kusebenza emathanjeni e-coccyx okukhulunywe ngawo (ekuthuthekeni) ekuzalweni kepha angahle aqhutshwe noma ahlangane ngokukhula kwabantu abadala.

Kungani i-L5-S1 ibalulekileIkholomu yomgogodla isakhiwo somzimba esivumela ukuthi sime siqonde futhi siphenduke futhi siguqule ukushintsha isikhundla sesifuba, emuva nangentamo. Ukuvuthwa komgogodla nakho kuyisihluthulelo ekungcupheni kwayo.
Emqaleni nangenhla ephansi, ijika lomgogodla lihamba phambili lapho lingenalo hlangothi, kuyilapho imisindvo ye-thoracic ne-sacral igxuma ngaphesheya
Ku-junction L5-S1 ukuthi isisindo somzimba sishintsha isiqondiso ukusuka phambili (i-lumbar) ngejika elingemuva (sacral). Kulezi zikhundla ezicindezelayo eziphikisayo ukwandisa ubungozi bokuhlangana njengeminyaka edlule noma ubuhlungu.
Ngenxa yalokhu, i-L5-S1 ingenye yezindawo ezimbili ezivame ukuhlinzwa emuva (kanye ne-L4-L5).

I-L5-S1 ne-SpondylolisthesisUkuhlangana kwe-L5-S1 kuyisayithi evamile yokulimala eyaziwa ngokuthi i- spondylolisthesis . I-spondylolisthesis ibhekisela ku-vertebra eye yahamba phambili ehlobene nethambo ngokushesha ngaphansi kwayo.
Uhlobo oluvame kakhulu lubizwa ngokuthi i-spondylolisthesis ye-isthmic eqala nge-fracture encane ku-pars interarticularis (isakhiwo sesithambo esixhuma amalunga omgogodla).
Ngenkathi i-fracture ivame ukuvela lapho umuntu esemncane (ngaphambi kweminyaka yobudala), izimpawu ngokuvamile aziyikukhula kuze kube umuntu omdala. Ukwehlukaniswa komgogodla uma umuntu esekhulile kungakwandisa isimo.
I-spondylolisthesis ithinta ukuhlanganyela kwe-L5-S1 ngenxa ye- angle ye-sacrum ngokwayo. Esikhundleni sokungena phezulu emhlabathini, amathiphu we-S1 phansi naphambili nasemuva. Ngokubanzi, abantu abanokuthambekela okukhulu bazogibela ingozi ephezulu ye-spondylolisthesis.
I-Spondylolisthesis ivame ukuphathwa ngokungenelela okungeyona yokuhlinzwa njengemithi yokwelashwa, ukushisa kanye / noma isicelo seqhwa, ukwelashwa ngokomzimba, noma izijovo ze-epidural steroid.
Ngenkathi ukuhlinzwa kwemfudu yomgogodla kungaphumelela ekwelapheni i-spondylolisthesis, kudinga isikhathi sokutakula okuningi futhi ngokuvamile akucatshangwa kuze kube yilapho umuntu ehlulekile ukuthola ukukhulula ezintweni ezingekho zokuhlinza okungenani izinyanga eziyisithupha.
