Razionale SInergy System
•
Dolore nocicettivo
•
Indicato nelle procedure di denervazione dell’articolazione
sacro-iliaca e per il dolore generato dei legamenti dorsali o
sacrali
•
Studi anatomici forniscono una guida per l’individuazione delle
branche laterali ed i forami sacrali. Le branche laterali sono
presenti ad ogni livello sacrale
•
Il numero delle branche laterali e della loro posizione (variabile)
superiore, inferiore e a diversa profondità dal piano sacrale,
necessita di lesioni ampie (1400-1500 mm3) a tutti I livelli trattati
S1-S3 in modo da creare ampie lesioni alle branche laterali

10
ESIGENZA DI TRATTAMENTO RF
•
Livello L5
– Lesione del ramo
dorsale primario/
ala sacrale
•
Livello S1, S2, S3
– Lesione di tutta la
branca laterale
all’uscita dal
forame

11
EFFETTIVA ABLAZIONE DELLA
BRANCA LATERALE
• Studi anatomici provvedono
alla localizzazione della branca
laterale
• Il sistema Cooled RF permette
una lesione ampia, controllata e
ripetibile
• Effettiva ablazione della branca
nervosa laterale nel trattamento
della giunzione sacro-iliaca

sacrale posteriore di S1, S2, S3 sotto immagine AP
• Infiltrare
• 1% Lidocaine nel sito d’ ingresso
– S1, S2: superiore, laterale, inferiore (R 2:30, 4, 5:30)
– S3: superiore, laterale (R 2,4)
• Inserire la cannula mandrinata fino al contatto con l’osso; misurare con
episilon le punte devono essere a 8-10 mm dal margine laterale del

• Fissare il marker sulla cute
• Rimuovere il mandrino(si estende per 6 mm oltre la punta della
cannula)

PROCEDURA
•
•
•
•
•
•
•
•
•
Posizionare il probe nella cannula(esce di 4 mm dalla cannula e di 2
mm dall’osso)
Proiezione laterale, per escludere di essere nel canale
Verificare l’impedenza 100 - 500 ohms
Iniziare il trattamento termico:
Durata: 2:30 mins
Temperatura 60°C ( durata applicazione 2,05 min.)
Rampa di 25 secondi
Rimuovere il probe,reinserire il mandrino, riposizionarsi sull’altro target
e ripetere il trattamento. Un solo punto di ingresso per ogni livello da
trattare
Per la lesione a L5 si utilizza una cannula standard da 18 gauge/ 10 mm

GEOMETRIA DI LESIONE
•
•
La lesione deve essere 8-10 mm dal margine laterale del forame
I siti da trattare dovrebbero essere ad una distanza di 50°
(1:40dell’orologio) per sopvrapporrre le lesioni

Il marker Epsilon può
essere usato per
giudicare la distanza dal
forame
La lesione deve essere a
8/10 mm dal margine
laterale del Psfa
Epsilon indica lo spazio
appropiato tra I siti
target; 2:30, 4:00, 5:30

CONCLUSIONI
• La metodica di ablazione con Sinergy system sembra
essere un opzione terapeutica estremamente
promettente per tutte le patologie dolorose della pelvi
oltre che dell’articolazione sacroiliaca.
• La casistica limitata non consente di dare una risposta
definitiva sul ruolo del Sinergy in confronto alla
neurostimolazione sacrale.
