Come leggo la risonanza e come decido"},"content":{"rendered":"\n<p class=\"wp-block-paragraph\">Arriva la busta con la risonanza. Si apre il referto e, tra parole difficili, ne spicca una: <strong>ernia<\/strong>. Da quel momento molte persone iniziano a immaginare la sala operatoria, il ricovero, settimane di stop dal lavoro.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Nel mio lavoro di chirurgo vertebrale questa \u00e8 una delle domande che mi fanno pi\u00f9 spesso: \u00abDottore, ho l&#8217;ernia del disco: devo operarmi?\u00bb. La risposta onesta \u00e8 che quasi sempre no. Non perch\u00e9 l&#8217;intervento non funzioni, ma perch\u00e9 la maggior parte delle ernie migliora con il tempo e con le cure giuste. In questo articolo ti spiego cosa dice davvero il referto, come ragiono quando devo decidere e in quali casi l&#8217;intervento diventa invece la scelta migliore.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Che cos&#8217;\u00e8 un&#8217;ernia del disco, in parole semplici<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Tra una vertebra e l&#8217;altra c&#8217;\u00e8 un disco, una specie di cuscinetto. Ha un anello esterno resistente e un nucleo interno pi\u00f9 morbido, gelatinoso. Il disco ammortizza i carichi e permette alla colonna di piegarsi e ruotare.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Con gli anni, o dopo sforzi ripetuti, l&#8217;anello esterno pu\u00f2 indebolirsi. Il nucleo allora spinge verso l&#8217;esterno. Nei referti trovi parole diverse a seconda di quanto \u00e8 uscito:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n\n<li><strong>bulging<\/strong> o <strong>protrusione discale<\/strong>: il disco sporge un po&#8217; oltre il suo bordo, come una gomma leggermente sgonfia;<\/li>\n\n\n<li><strong>ernia espulsa<\/strong> (estrusione): una parte del nucleo \u00e8 uscita in modo pi\u00f9 netto;<\/li>\n\n\n<li><strong>ernia migrata<\/strong> o <strong>sequestrata<\/strong>: un frammento si \u00e8 staccato e si \u00e8 spostato.<\/li>\n\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Il dolore nasce quando il materiale del disco tocca e irrita una radice nervosa. Nella schiena bassa, a livello L4-L5 o L5-S1, questo provoca la classica <strong>sciatica<\/strong>: un dolore che scende lungo la gamba, a volte fino al piede, con formicolio.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">La risonanza fotografa, non fa la diagnosi<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Questo \u00e8 il punto pi\u00f9 importante dell&#8217;articolo. La risonanza \u00e8 un esame splendido: mostra il disco, i nervi e le vertebre con grande dettaglio. Ma \u00e8 una fotografia. Non dice da sola se quello che vediamo \u00e8 la causa del tuo dolore.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Lo sappiamo da molti anni. Gi\u00e0 nel 1994 uno studio pubblicato sul New England Journal of Medicine aveva fatto la risonanza lombare a 98 persone <strong>senza nessun mal di schiena<\/strong>: pi\u00f9 della met\u00e0 aveva un disco sporgente in almeno un livello e circa una su quattro una protrusione.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Nel 2015 una revisione di 33 studi su oltre 3.100 persone senza dolore ha confermato il dato: la protrusione discale si trova gi\u00e0 nel 29% dei ventenni, e a 80 anni l&#8217;84% ha un disco che sporge. Sono, in gran parte, segni normali dell&#8217;invecchiamento della colonna, come i capelli bianchi.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/orthonext.it\/wp-content\/uploads\/2026\/10\/ernia1026\/infografica-risonanza-fotografa.jpg\" alt=\"Infografica: la risonanza fotografa, non fa la diagnosi, dal carosello del Dr. Lavanga\"\/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Per questo non guardo mai la risonanza da sola. Il referto descrive un&#8217;immagine; io curo una persona.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Come ragiono quando devo decidere<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Quando un paziente entra con la sua risonanza, la prima cosa che faccio \u00e8 ascoltare e visitare. Poi metto insieme tre domande.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">1. Il dolore scende nella gamba lungo il nervo che l&#8217;ernia tocca?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Ogni radice nervosa ha un suo percorso nella gamba. Se l&#8217;ernia \u00e8 a L5-S1 sul lato sinistro e il dolore scende proprio lungo il territorio di S1 a sinistra, immagine e sintomi coincidono. Se invece il dolore \u00e8 solo nella schiena, o sull&#8217;altro lato, o in una zona che quel nervo non raggiunge, l&#8217;ernia probabilmente non \u00e8 la protagonista.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. C&#8217;\u00e8 perdita di forza o di sensibilit\u00e0 che peggiora?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Durante la visita controllo la forza dei muscoli della gamba e del piede, i riflessi e la sensibilit\u00e0. Un formicolio stabile \u00e8 comune e di solito migliora. Un piede che diventa sempre pi\u00f9 debole, per esempio quando non si riesce pi\u00f9 a camminare sui talloni o sulle punte, \u00e8 un segnale diverso, da non lasciare correre.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. Come cambia il dolore settimana dopo settimana?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Il tempo \u00e8 un grande alleato nella diagnosi. Un dolore che, con movimento e terapia, si riduce un po&#8217; ogni settimana mi dice che stiamo andando nella direzione giusta. Un dolore che resta bloccato, forte e invalidante, nonostante settimane di cure fatte bene, mi fa pensare in modo diverso.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Quando non serve operarsi<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Nella grande maggioranza dei casi:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n\n<li><strong>il dolore migliora nelle settimane<\/strong>: il corpo riassorbe una parte dell&#8217;ernia, soprattutto quando \u00e8 grande ed espulsa;<\/li>\n\n\n<li><strong>forza e sensibilit\u00e0 sono normali<\/strong>, o hanno solo alterazioni lievi e stabili;<\/li>\n\n\n<li><strong>si cura con il movimento<\/strong>, con farmaci per il dolore usati bene, con fisioterapia mirata e, se serve, con un&#8217;infiltrazione.<\/li>\n\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Sembra strano, ma le ernie pi\u00f9 grandi sono spesso quelle che si riducono di pi\u00f9. Il materiale uscito dal disco viene riconosciuto dal sistema immunitario come estraneo e lentamente &#8220;ripulito&#8221;.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Una cosa che ripeto sempre: <strong>restare a letto non aiuta<\/strong>. Muoversi entro i limiti del dolore, camminare un po&#8217; ogni giorno e riprendere gradualmente le attivit\u00e0 fa parte della cura. Ne ho parlato in modo pi\u00f9 completo nell&#8217;articolo sulla <a href=\"https:\/\/vitolavanga.it\/sciatica-acuta-letto-o-movimento\/\" target=\"_blank\" rel=\"noopener\">sciatica acuta e i primi 7 giorni<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Quando invece s\u00ec<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Ci sono situazioni in cui l&#8217;intervento \u00e8 la scelta giusta, e a volte va fatto in fretta:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n\n<li><strong>urgenza<\/strong>: disturbi a urinare o a trattenere le feci, oppure formicolio o perdita di sensibilit\u00e0 &#8220;a sella&#8221;, cio\u00e8 nella zona dell&#8217;inguine e dell&#8217;interno cosce. Sono i segni di una possibile sindrome della cauda equina: <strong>vai subito in Pronto Soccorso<\/strong>;<\/li>\n\n\n<li><strong>il piede o la gamba perdono forza sempre di pi\u00f9<\/strong>, nonostante le cure;<\/li>\n\n\n<li><strong>dopo 6-12 settimane di cure ben fatte il dolore blocca ancora la vita<\/strong>: non riesci a lavorare, a dormire, a camminare.<\/li>\n\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">In questi casi l&#8217;intervento, di solito una microdiscectomia che rimuove solo il frammento che comprime il nervo, d\u00e0 un sollievo rapido alla gamba. Il tipo di intervento e il momento giusto li decido caso per caso, insieme al paziente, spiegando sempre cosa faremo e perch\u00e9.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Cosa dice la scienza<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n\n<li><strong>Ernie e dischi sporgenti in chi non ha dolore.<\/strong> Lo studio di Jensen e colleghi sul <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/8208267\/\" target=\"_blank\" rel=\"noopener\">New England Journal of Medicine (1994)<\/a> ha mostrato dischi sporgenti in pi\u00f9 della met\u00e0 di 98 persone senza mal di schiena. La revisione sistematica di Brinjikji e colleghi su <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/25430861\/\" target=\"_blank\" rel=\"noopener\">AJNR (2015)<\/a>, con 33 studi e 3.110 persone senza sintomi, ha trovato protrusioni nel 29% dei ventenni e dischi sporgenti nell&#8217;84% degli ottantenni.<\/li>\n\n\n<li><strong>Molte ernie si riducono da sole.<\/strong> Una revisione sistematica su <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/25009200\/\" target=\"_blank\" rel=\"noopener\">Clinical Rehabilitation (2015)<\/a> ha stimato che la regressione spontanea avviene nel 96% delle ernie sequestrate, nel 70% delle espulse, nel 41% delle protrusioni e nel 13% dei bulging. Una meta-analisi di 11 studi su <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/28072796\/\" target=\"_blank\" rel=\"noopener\">Pain Physician (2017)<\/a> ha calcolato un riassorbimento spontaneo in circa due casi su tre.<\/li>\n\n\n<li><strong>Operare subito o aspettare?<\/strong> Nello studio randomizzato di Peul e colleghi sul <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/17538084\/\" target=\"_blank\" rel=\"noopener\">New England Journal of Medicine (2007)<\/a>, 283 persone con sciatica forte da 6-12 settimane sono state assegnate all&#8217;intervento precoce o alle cure conservative prolungate. Chi \u00e8 stato operato subito ha avuto un sollievo pi\u00f9 rapido, ma a un anno i risultati erano simili nei due gruppi.<\/li>\n\n\n<li><strong>Lo studio SPORT.<\/strong> Nello studio randomizzato pubblicato su <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/17119140\/\" target=\"_blank\" rel=\"noopener\">JAMA (2006)<\/a> entrambi i gruppi, operati e non operati, sono migliorati molto. Il follow-up a otto anni su <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/24153171\/\" target=\"_blank\" rel=\"noopener\">Spine (2014)<\/a> mostra un vantaggio duraturo dell&#8217;intervento nei pazienti selezionati, ma conferma che anche senza intervento la maggior parte migliora.<\/li>\n\n\n<li><strong>Le linee guida.<\/strong> La linea guida della North American Spine Society su <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/24239490\/\" target=\"_blank\" rel=\"noopener\">Spine Journal (2014)<\/a> riassume queste prove: la diagnosi si basa sull&#8217;insieme di sintomi, visita e immagini, e l&#8217;intervento \u00e8 indicato nei casi selezionati.<\/li>\n\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>I limiti.<\/strong> Questi studi non sono tutti uguali: in SPORT molti pazienti hanno cambiato gruppo durante lo studio, e le percentuali di riassorbimento variano molto da uno studio all&#8217;altro. Per questo nessun numero sostituisce la valutazione della singola persona.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Domande frequenti<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Se l&#8217;ernia \u00e8 grande devo per forza operarmi?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">No. La grandezza dell&#8217;ernia da sola non decide. Anzi, le ernie grandi ed espulse sono quelle che pi\u00f9 spesso si riassorbono. Contano i sintomi, la forza e come va il dolore nel tempo.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Devo rifare la risonanza per vedere se l&#8217;ernia si \u00e8 ridotta?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Di solito no. Se stai meglio, l&#8217;immagine conta poco. Una nuova risonanza serve se i sintomi cambiano, se peggiorano o se stiamo valutando un intervento.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Le infiltrazioni servono?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">In alcune persone con sciatica forte un&#8217;infiltrazione vicino alla radice nervosa riduce il dolore per qualche settimana, il tempo necessario perch\u00e9 l&#8217;ernia si riduca e la riabilitazione faccia il suo lavoro. Non \u00e8 adatta a tutti e la valuto caso per caso.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Dopo l&#8217;intervento l&#8217;ernia pu\u00f2 tornare?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Pu\u00f2 succedere, in una parte dei pazienti. Per questo, dopo l&#8217;intervento, \u00e8 importante un percorso di riabilitazione e di rinforzo che protegga la schiena nel tempo.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Hai un referto e non sai cosa fare?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Se hai una risonanza con scritto &#8220;ernia del disco&#8221; e non sai come muoverti, possiamo guardarla insieme, con i tuoi sintomi, e decidere il passo giusto.
