متن کاملIntra-operative identification of conjoined lumbosacral nerve roots: a report of three cases.
We report 3 cases of conjoined nerve root anomalies identified during micro-endoscopic discectomy (MED). Between 2009 and 2010, 61 men and 20 women aged 18 to 84 (mean, 42) years underwent MED for symptomatic lumbar disc herniation of L3-4 (n=1), L4-5 (n=44), and L5-S1 (n=36). Magnetic resonance imaging (MRI), myelogram, and postmyelo computed tomography did not identify the anomalies. All 3 pa...
متن کاملConjoined lumbosacral nerve roots: observations on three cases and review of the literature.
Lumbosacral nerve root anomalies are a rare group of congenital anatomical anomalies. Various types of anomalies of the lumbosacral nerve roots have been documented in the available international literature. Generally speaking, these anomalies may consist of a bifid, conjoined structure, of a transverse course or of a characteristic anastomized appearance. Firstly described as an incidental fin...
متن کاملAnomalies of the lumbosacral nerve roots.
The congenital anomalies of the lumbosacral nerve roots have frequently been found in the past as operative findings during surgery for protruded disc and are today diagnosed preoperatively with increasing frequency. They include the more cranial or more caudal origin of a nerve root, the conjoined structure of two roots and the anastomoses between two or more roots. This study reviews the larg...
متن کاملMR of enhancing nerve roots in the unoperated lumbosacral spine.
PURPOSE To evaluate prospectively the unoperated lumbosacral spine by gadolinium-enhanced MR for evidence of clinically correlative abnormal enhancement of nerve roots. METHODS Two hundred patients were prospectively studied with intravenous gadolinium- (0.1 mmol/kg) enhanced MR. Evidence was sought of intrathecal enhancement of lumbosacral nerve root(s), and the correlation of this enhanceme...
