Abstract
A method for needle positioning for lead implantation for sacral neuromodulation uses fluoroscopy to locate anatomical landmarks. Markings on the skin of the patient are made to determine optimal positioning of a foramen needle used to position the leads and electrodes of an implantable electrical stimulator.
Claims18
A method for positioning a foramen needle to implant a lead of an electrical stimulator for sacral neuromodulation of a patient, the method comprising:
- visualizing with fluoroscopy an anterior/posterior view of the sacrum and sacroiliac joints of the patient;
- marking on the skin of the patient a midline of the sacrum vertically and a horizontal line from one sacroiliac joint to the other sacroiliac joint;
- marking a first point on the horizontal line located a first distance in a first lateral direction from the sacral midline, wherein the first distance approximates a first midline of a desired sacral foramen;
- locating the first midline of the desired sacral foramen using the fluoroscopic anterior/posterior view and the first point and marking the skin of the patient with a first midline vertical line;
- marking the skin of the patient at a second distance and a third distance from the horizontal line superiorly on the first midline vertical line, thereby approximating where the desired foramen should be located to place the needle;
- marking the skin of the patient with a first medial vertical line representing the medial portion of the first sacral edge using the fluoroscopic anterior/posterior view;
- locating the desired sacral foramen with fluoroscopy in a lateral view;
- placing the needle through the skin at an angle using the skin markings at one of the second and third markings, beginning medially at the first midline vertical line and progressing laterally to the first medial vertical line until a distal end of the needle drops into the desired sacral foramen.

- marking on the skin of the patient a midline of the sacrum vertically and a horizontal line from one sacroiliac joint to the other sacroiliac joint;
- marking a first point on the horizontal line 2 cm in a first lateral direction from the sacral midline and a second point on the horizontal line 2 cm in a second lateral direction from the sacral midline;
- locating a first midline of a desired sacral foramen using the fluoroscopic anterior/posterior view and the first point and marking the skin of the patient with a first midline vertical line;
- locating a second midline of another desired sacral foramen using the fluoroscopic anterior/posterior view and the second point and marking the skin of the patient with a second midline vertical line, the another desired sacral foramen opposite the desired sacral foramen;
- marking the skin of the patient at 4 cm and 5 cm from the horizontal line superiorly on the first midline vertical line, thereby approximating where the desired foramen should be located to place the needle;
- marking the skin of the patient at 4 cm and 5 cm from the horizontal line superiorly on the second midline vertical line, thereby approximating where the another desired foramen should be located to place the needle;
- marking the skin of the patient with a first medial vertical line representing the medial portion of the first sacral edge using the fluoroscopic anterior/posterior view;
- marking the skin of the patient with a second medial vertical line representing the medial portion of the second sacral edge using the fluoroscopic anterior/posterior view;
- locating the desired sacral foramen with fluoroscopy in a lateral view;
- placing the needle through the skin at an angle using the skin markings at one of the 4 cm and 5 cm markings, beginning medially at the first midline vertical line and progressing laterally to the first medial vertical line until a distal end of the needle drops into the desired sacral foramen.
