Spinal cord herniation (SCH) is a rare cause of myelopathy. When reported, SCH has most commonly been described as occurring spontaneously in the thoracic spine, and being idiopathic in nature (anterior thoracic spinal cord herniation, ATSCH) [1-3]. Several theories have been proposed to explain its occurrence, including congenital, inflammatory, and traumatic etiologies alike [1-4]. Even more rarely, SCH has been described to occur in the cervical spine in association with brachial plexus avulsion injuries (BPAI-SCH). In our accompanying article, "Late Cervical Spinal Cord Herniation Resulting from Post-Traumatic Brachial Plexus Avulsion Injury," two cases of BPAI-SCH are presented and discussed in the context of the reviewed literature [5]. Here, pertinent accompanying follow-up data was collected and is presented for the cases, including postoperative radiographic outcome imaging. Furthermore, a table is presented comparing and contrasting ATSCH to BPAI-SCH. Although the two phenomena have been previously grouped together, this table highlights ATSCH and BPAI-SCH as distinct entities; more specifically, BPAI-SCH is a separate, long-term complicating feature of BPAI. This supplementary data helps treating physicians by increasing awareness and knowledge of BPAI-SCH as a distinct entity from ATSCH and cause of delayed neurological deterioration.
脊髓疝（SCH）是脊髓病的一种罕见病因。据报道，SCH最常见于胸椎自发出现，本质上为特发性（胸段脊髓前疝，ATSCH）[1-3]。人们提出了几种理论来解释其发生原因，包括先天性、炎症性和创伤性病因等[1-4]。更罕见的是，SCH被描述为与臂丛神经撕脱伤相关的颈椎病变（臂丛神经撕脱伤相关性脊髓疝，BPAI-SCH）。在我们的随附文章《创伤后臂丛神经撕脱伤导致的迟发性颈椎脊髓疝》中，介绍了两例BPAI-SCH病例，并结合文献进行了讨论[5]。在此，收集了相关的随诊数据并呈现这些病例，包括术后影像学结果。此外，还给出了一个表格，对ATSCH和BPAI-SCH进行比较和对比。尽管这两种现象之前被归为一类，但该表格突出了ATSCH和BPAI-SCH是不同的实体；更具体地说，BPAI-SCH是BPAI一种独立的、长期的并发症特征。这些补充数据有助于治疗医生提高对BPAI-SCH作为一种与ATSCH不同的实体以及延迟性神经功能恶化原因的认识和了解。
