Based on medullary traction as responsible for idiopathic syringomyelia (SMI), idiopathic scoliosis (ESCID), Arnold Chiari malformation (ARCH), platybasia (PTB), basilar impression (IMB), odontoid recess (RTO) kinking of the brain stem (KTC) and considering the medullary traction to be transmitted by the filum terminale (FT), a surgical technique for the section of FT (SFT) is described in three cases of SMI, one of ESCID, and one of ARCH with no lumbar dysraphia.


A 34-year-old woman with cervico-brachialgias, paresthesias, bilateral babinski and a centro-medullary cavity C3-C7. A 26-year-old male with cervico-brachialgias, hypoestesia in left hemybody, and cervicobulbar cavity. A 19-year-old female with ESCID since the age of 14th, with episodes of reacuting, and 38o of dorsolumbar curvature. A 67-year-old woman with intense headache, hypoesthesia of the hands, paraparesia and ARCH. A 23-year-old man with marked tetraparesia, bilateral babinski, anesthesia of both legs, SMI, ESCID, ARCH and hydrocephaly.


After SFT: in the SMIs the thermo-algesic, disesthetic and algic dissociation disappeared. In ESCID there was a reduction to 31o in the curvature in nine months. On ARCH the headaches ceased and there was recovery of touch and paraparesia.


SFT is a useful etiological treatment for SMI, ESCID, ARCH. Also, in ESCID it is possible to avoid stress on the medulla due to its surgical reduction.
