The minimally invasive surgical technique under local anaesthesia for the section of the extradural tract of the filum terminale can only have a possible skin infection at the level of the surgical incision as a complication.
To avoid this possibility, the protocol provides antibiotic prophylaxis in the operating room before the start of the surgery.
The skin cut is about 4 cm long and is made at the level of the sacral hiatus.
No bone tissue is removed from the vertebrae or sacrum.
The posterior sacrococcygeal ligament is removed, and using the microsurgical technique, which involves using the operating microscope, the extradural filum terminale is isolated and cut.

Having neither meninges nor nervous structures in the operating field, there can be no neurological damage or the appearance of meningitis.
The surgery takes about 25 minutes, and you can walk again after 60-120 minutes.
The patient is discharged from the hospital the day after the surgery.
The surgical intervention for anatomical reasons does not foresee the opening of the meninges; therefore, with this minimally invasive surgical technique, there are no conditions for the complication of the re-anchoring described in the surgical interventions with traditional surgery under general anaesthesia.
