Tethering of the spinal cord in the lumbosacral region with myelomeningocele is a well-known phenomenon. Only sporadic cases of tethering along the rest of the neuraxis, including the hindbrain, cervical, and thoracic spinal cord have been documented, always along with some associated congenital malformations (hydrocephalus, Chiari malformation, myelomeningocele, meningocele, hamartomatous stalk, spina bifida occulta, intramedullary lipoma, intradural fibrous adhesions, the fusion of the sixth and seventh cervical vertebrae, split cord malformation, or low-lying cord). In this report, 14-year-old male developed symptoms related to tethering of the cervical spinal cord, but without any associated congenital malformations, that is the pure tethered cervical cord. This causes his moribund status and makes the manuscript unique and contributes to the hitherto literature. The authors discuss the diagnosis, treatment, and postoperative course of this entity. The uniqueness in treatment is that we have operated the case without the help of intraoperative somatosensory evoked potentials and motor evoked potential from posterolateral approach under local anesthesia.

Background:The existing Intraoperative MRI (IMRI) of developed countries is too costly to be affordable in any developing country and out of the reach of common and poor people of developing country at remote areas. We have used the pre-existing (refurbished) 3 side open “C” shaped 0.2 Tesla MRI for IMRI in a very remote area.Materials and Methods:In this technique the 0.2 Tesla MRI and the operating theatre were merged. MRI table was used as an operation table. We have operated 36 cases via IMRI from November 2005 to till date. First case operated was on 13th nov 2005.Results:Low (0.2) Tesla open setup costs very low (around Rs 40 lakhs) so highly affordable to management and thus to patients, used for diagnostic and therapeutic purposes both, the equipments like Nitrous, oxygen and suction is outside the MRI room so no noise inside operative room, positioning the patient didn’t take much time due to manual adjustments, no special training to nurses and technicians required because of low (0.2) Tesla power of magnet and same instruments and techniques, sequencing took only 1.31 mints per sequence and re registration is not required since we always note down the two orthogonal axis in x and y axis in preoperative imaging and we were able to operate on posterior fossa tumors as well because of no head fixation except with leucoplast strap. Moreover the images we got intraoperative are highly acceptable.Conclusion:Three side open 0.2 Tesla MRI system, if used for intraoperative guidance, is highly affordable and overcomes the limitations of western setup of IMRI. Postoperative MRI images were highly acceptable and also highly affordable too.
