Abstract

BACKGROUND

An incidental dural tear is a well-known complication during spine surgery. A rare consequence is a postoperative nerve root herniation. The purpose of this report is to describe a case of such a herniation with entrapment in the facet gap joint and to present the first MR images of this rare surgical complication.

CASE PRESENTATION

We report a case of a patient who underwent lumbar decompression surgery and afterwards suffered a sudden intractable sciatica. Postoperative MRI showed a new facet joint gap effusion. During revision surgery an entrapped nerve root was found in the facet joint gap. In retrospective, the herniated nerve root is visible on postoperative MRI.

CONCLUSION

This case report highlights a rare complication during spine surgery. This finding is important as signs suggestive for nerve root herniation can easily be overlooked on MRI. Furthermore, this represents the first MRI documentation of this complication.

摘要

背景

硬脊膜意外撕裂是脊柱手术中众所周知的并发症。一种罕见的后果是术后神经根疝出。本报告的目的是描述一例这种疝出并嵌顿在小关节间隙的病例，并展示这种罕见手术并发症的首例磁共振成像（MRI）图像。

病例介绍

我们报告了一例患者，该患者接受了腰椎减压手术，随后出现突发的难治性坐骨神经痛。术后 MRI 显示新的小关节间隙积液。在翻修手术中，发现神经根嵌顿在小关节间隙中。回顾性分析，术后 MRI 上可见疝出的神经根。

结论

本病例报告强调了脊柱手术中的一种罕见并发症。这种发现很重要，因为 MRI 上神经根疝出的提示性征象很容易被忽视。此外，这代表了该并发症的首例 MRI 记录。
