Uluphi uL5-S1 kunye neLumbosacral Joint?

Icandelo loMgcini ngokugqithiseleyo onokuThatshazwa

I-L5-S1 ligama elisetyenziselwa ukuchaza icandelo lomgudu oqulethwe nge-vertebra yokugqibela yomqolo ongaphantsi (obizwa ngokuba ngu-L5) kunye namathambo enesantathu. I-sacrum iqulethwe ngamathambo amahlanu apho iS1 iphezulu.

Unokucinga nge-L5-S1 njengendawo echanekileyo apho i- lumbar spine iphelile kwaye i-sacral spine iqala. Umdibaniso odibanisayo ubizwa ngokuba ngumxube we-lumbosacral.

Ulwakhiwo lweLumbar Spine neSigrum

Umgudu womntu unama-33 angama-33 angama-24 angaphezulu kuphela ahambayo. Zidilizwe zibe ngamacandelo ukusuka phezulu ukuya emsila, ngale ndlela:

• Umlomo wesibeletho (intamo) kunye namathambo asixhenxe ukusuka kwiC1 ukuya kwiC7
• I-Thoracic spine (emva emva) kunye ne-bone ye-T1 ukuya kwi-T12
• I-Lumbar spine (ephantsi) kunye namathambo amahlanu ukusuka eL1 ukuya ku-L5
• I-sacrum ngamathambo amahlanu ukusuka kwi-S1 ukuya kwi-S5
• Ummandla weCoccyx (tailbone) ngamathambo amane ukusuka kwi Co1 ukuya kwiCo4

Ngelixa abaninzi abantu bavame ukucinga nge- sacrum njengethambo elinye, ngokuqinisekileyo liqukethe amathambo amahlanu aqala ukuxhamla emva nje kokuzalwa aze aqhube ukwenza oko ade adibaniswe ngokupheleleyo eneminyaka engama-30.

Kuyafana nakwamathambo e-coccyx (ahambayo) ekuzalweni kodwa mhlawumbi angagxothwa okanye athathwe ngumntu omdala.

Kutheni i-L5-S1 ibalulekile

Umqolo wamagxa ngumzimba womzimba osivumela ukuba simile ngokuthe tye kwaye siphendule size siguqule ukutshintsha isikhundla sesibini, umva, nentamo. Ukukhawulwa komgudu kuyintloko nakwiindawo zokungabikho.

Eentanyeni nasemqolo ophantsi, umzila wamagulane uqhube phambili xa ungathathi hlangothi, ngelixa i-thoracic ne-sacral curves ishayela kwelinye icala

Kulo mkhonkco we-L5-S1 ukuba isisindo somzimba sitshintsha isalathiso esivela phambili (lumbar) kwikhava ukuya ngasemva (sacral) curve. Kule ngqungquthela exinzelelekileyo ingcinezelo yandisa ubungozi bokubambisana njengeminyaka emva okanye ephazamisekile.

Ngenxa yoko, i-L5-S1 yenye yezona zibini eziqhelekileyo ukuhlinzwa ngokutsha (kunye ne-L4-L5).

I-L5-S1 kunye ne-Spondylolisthesis

Ukuhlangana kwe-L5-S1 yindawo eqhelekileyo yokulimala okubizwa ngokuba yi- spondylolisthesis . I-Spondylolisthesis ibhekisele kwi-vertebra eye yahamba phambili malunga nesithambo ngokukhawuleza phantsi kwayo.

Uhlobo oluqhelekileyo lubizwa ngokuba yi-isthmic spondylolisthesis eqala ngokuqhekeka okuncane kwi-pars interarticularis (isakhiwo sesithambo sidibanisa amalunga omgudu).

Ngoxa i-fracture iqala ukufika xa umntu eselula (ngaphambi kweminyaka engama-7), iimpawu ngokuqhelekileyo aziyi kukhula kuze kube ngumdala. Ukutshatyalaliswa komgudu emva komntu osemdala kungaphaya kokunyusa imeko.

I-Spondylolisthesis ichaphazela ukudibanisa kwe-L5-S1 ngenxa yecala le-sacrum ngokwayo. Kunokuba ibe yindawo ephantsi komhlaba, i-S1 izicwangciso ezisezantsi naphambili emva. Ngokubanzi, abantu abanomtsalane omkhulu baya kuqhuba umngcipheko ophezulu we-spondylolisthesis.

I-Spondylolisthesis iphathwa ngokungenelelo olungaphelelwanga njengamachiza enhlungu, ukushisa kunye / okanye isicelo seqhwa, unyango lomzimba okanye iinjongo ze-epidural steroid.

Nangona utyando lwe-spinal fusion lunokuphumelela ekuphatheni i-spondylolisthesis, lifuna ixesha elide lokubuyiselwa kwaye ngokuqhelekileyo lucingelwa de kube umntu engaphumeleli ekufumaneni ukukhululeka kwiindlela ezingekho iindlela zokugonywa ubuncinane ubuncinane kweenyanga ezintandathu.
