UNASSIGNED: OBJECT @entity129 ( @entity129 ) @entity16 (SCNEN) is a cause of @entity1643 ( @entity1643 ) that can be misdiagnosed as a lumbar spine disorder. The clinical features and etiology of @entity1643 remain poorly understood. In this study, 5 @entity1 with intermittent @entity1643 due to SCNEN who had previously received conservative treatment underwent surgery. The findings are reported and the etiology of @entity1643 is discussed to determine whether it is attributable to SCNEN. METHODS Intermittent @entity1643 is defined as a clinical condition in which @entity158 is induced by standing or walking but is absent at rest. Between April 2012 and March 2013, 5 @entity1 in this study who had intermittent @entity1643 due to SCNEN underwent surgery. The @entity1 included 3 @entity1 and 2 @entity1 , with a mean age of 66 years. The affected side was unilateral in 2 @entity1 and bilateral in 3 (total sites, 8). The interval from symptom onset to treatment averaged 51.4 months; the mean postoperative follow-up period was 17.6 months. The clinical outcomes were assessed using the numerical rating scale (NRS) for @entity1643 , the Japanese Orthopaedic Association (JOA) scale, and the Roland-Morris Disability Questionnaire (RDQ) preoperatively and at the last follow-up; these data were analyzed statistically. RESULTS None of the 5 @entity1 reported @entity1643 at rest. Intermittent @entity1643 involving the iliac crest and buttocks was induced by standing or walking an average of 136 m. In 2 @entity1 with unilateral involvement, @entity1643 was improved only by @entity616 . Surgeries were performed on 6 sites in 5 @entity1 because the @entity616 was only transiently effective. @entity1 ' SCNs penetrated the orifice of the thoracolumbar fascia. @entity129 kinking at the orifice was exacerbated at the lumbar-extension provocation posture, and radiating @entity158 increased upon manual intraoperative compression of the @entity129 in this posture. After releasing the @entity129 surgically, disappearance of the @entity158 was intraoperatively confirmed by manual compression of the @entity129 with the @entity1 in the lumbar-extension posture. Surgery was effective in all 5 @entity1 , and all clinical outcome scores indicated significant improvement (p < 0.05). CONCLUSIONS To the authors' knowledge, this is the first report of @entity1 with intermittent @entity1643 due to SCNEN. Clinical and surgical evidence presented suggests that their @entity1643 was exacerbated by lumbar extension and that symptom relief was obtained by @entity616 or surgical release of the @entity129 entrapment. These results suggest that SCNEN should be considered as a causal factor in @entity1 for whom walking elicits @entity1643 .
