Abstract:
OBJECTIVES:In complex lumbosacral lipomatous malformation or retethering, 'crotch' dissection, an incision on the dura or lipoma at the site lateral to the lipoma-cord fusion line saving underlying roots, is often not easy. Attempts of this dissection in complex and obscured conditions may cause damage to the spinal cord or nerve roots. A method for caudal extension of untethering while positive areas on electrical stimulation were encountered during crotch dissection of lumbosacral lipomatous malformation is described. METHODS:After thinning out the negative-response area just caudal to the positive-response area, a small perforation is made at the negative-response area skipping the positive-response area with probing the dissection direction through the subarachnoid space by an inside out fashion. Subsequently, the procedure is continued caudally from the perforation site. RESULTS:Safe caudal extension of untethering is possible using this method. Illustrative operative photographs are shown. CONCLUSION:By using this method, safe untethering can be achieved avoiding root injuries in complicated lipomas such as chaotic or re-tethering cases.
