TILF ke eng?
TLIF ke mokhoa o le mong bakeng sa fusion ea interbody ho tsosolosa sebaka se tloaelehileng sa sebaka sa intervertebral le lumbar spine physiological lordosis.Mokhoa oa TLIF o ile oa tlalehoa ka lekhetlo la pele ke Harms ka 1982. E khetholloa ke mokhoa o ka morao, o kenang mokokotlong oa mokokotlo ho tloha ka lehlakoreng le leng.Ho finyella mahlakore a mabeli vertebral 'mele fusion, ha ho hlokahale ho kena-kenana le kanale bohareng, e leng ho fokotsa ketsahalo ea cerebrospinal mokelikeli dutla, ha ho hlokahale ho otlolla methapo ea kutlo motso le dural sac haholo, le ho fokotsa monyetla oa ho senya methapo ea kutlo.Li-contralateral lamina le li-facet joints li bolokiloe, sebaka sa lesapo sa lesapo sea eketseha, 360 ° fusion e ka khoneha, li-ligamente tsa supraspinous le interspinous li bolokiloe, tse ka tsosolosang sebopeho sa mokokotlo oa mokokotlo oa mokokotlo oa mokokotlo.
PILF ke eng?
PLIF (posterior lumbar interbody fusion) ke mokhoa oa ho buoa bakeng sa ho kopanya lesapo la mokokotlo ka ho tlosa intervertebral disc le ho e nkela sebaka ka (titanium).Joale li-vertebrae li tsitsisoa ke fixator ea ka hare (transpedicular instrumented dorsal WK fusion).PLIF ke ts'ebetso e thata ea mokokotlo
Ho fapana le ALIF (anterior lumbar intervertebral fusion), opereishene ena e etsoa ho tloha ka morao, ke hore ho tloha ka morao.Phapang ea opereishene ea PLIF ke TLIF ("transforaminal lumbar interbody fusion").
E sebetsa joang?
Likotlolo tsa PEEK tsa mokokotlo oa mokokotlo li na le mahlaseli a mangata haholo, li-bio-inert, 'me li lumellana le MRI.Cage e tla sebetsa e le sets'oants'o sa sebaka pakeng tsa vertebrae e amehileng, ebe e lumella lesapo hore le hōle 'me qetellong le fetohe karolo ea mokokotlo.
Lipontšo
Lipontšo li ka kenyelletsa: bohloko ba mokokotlo oa discogenic / facetogenic, claudication ea neurogenic, radiculopathy ka lebaka la foraminal stenosis, lumbar degenerative spinal deformity ho akarelletsa le matšoao a spondylolisthesis le degenerative scoliosis.
Molemo
Motsoako o tiileng oa cage o ka felisa ho sisinyeha, ho eketsa sebaka sa metso ea methapo, ho tsitsisa mokokotlo oa mokokotlo, ho tsosolosa lesapo la mokokotlo, le ho kokobetsa bohloko.
