The case of an adult patient with lumbar radiculopathy (L:4) caused by a migrated silverclip, which was probably lost during the successful extirpation of a cerebellar tumor many years before is presented. The clip was removed surgically and the nerve root was submitted to a partial neurolysis. Increased tension in the root due to corrosion of the clip and scar formation is the proposed pathophysiological mechanism in this case.
本文介绍了一例成年患者，其因一枚移位的银夹导致腰神经根病（L4），该银夹可能是多年前在成功切除小脑肿瘤时丢失的。通过手术取出了银夹，并对神经根进行了部分神经松解术。该病例推测的病理生理机制是，银夹腐蚀和瘢痕形成导致神经根张力增加。
