文题释义:
颈椎前路椎体次全切除减压融合术:最早出现于20世纪60年代,经过不断改良被公认为治疗颈椎退变性病变的安全且有效的手术方式之一。由于能够对脊髓前方的压迫进行直接减压,同时维持颈椎局部的稳定性,该术式被国内外脊柱外科医生普遍采用。术中多采用钛制外科网填充自体碎骨作为切除椎体的替代物。
钛网下沉:又称为钛网沉陷,是颈椎前路椎体次全切除术后常见的并发症之一,指术后钛制外科网部分陷入手术节段相邻椎体内部,多表现为手术节段椎间高度的下降。当植入骨与周围骨质达到固定融合后,钛网下沉一般不再继续进展。目前,钛网下沉的发生被认为与骨密度、手术操作及钛网形态有关。
 
摘要
背景:颈椎前路椎体次全切除伴钛网植入术是颈椎脊髓压迫性病变常规有效的治疗方式之一,其术后并发症尤其是钛网下沉较为多见。钛网下沉的危险因素及对手术效果的影响目前仍存在争议。
目的:观察颈椎前路椎体次全切除伴钛网植入术后钛网下沉的发生情况及对修复效果的影响,分析其原因探索可能的危险因素。
方法:回顾性分析2015年3至9月于解放军第二军医大学附属长征医院脊柱二科行颈椎前路椎体次全切除伴钛网植入术34例患者的临床资料,随访12个月,测量患者手术节段椎间高度,计算颈椎JOA评分。随访时椎间高度较术后1 d下降超过3 mm即定义为钛网下沉,将患者分为下沉组及非下沉组。
结果与结论:①共有19例患者出现术后钛网下沉,发病率为56%,平均发生于术后(6.00±3.73)个月;②下沉组与非下沉组患者年龄、性别构成、手术节段数之间差异均无显著性意义(P=0.731,0.672,0.053);③通过颈椎JOA评分计算改善率,非下沉组患者术后改善率显著高于下沉组(P=0.01),提示钛网下沉与术后神经功能改善不佳可能有一定联系;④综上所述,颈椎前路椎体次全切除术后钛网下沉较为常见,而且会影响颈椎修复效果。患者年龄、性别、手术节段均不是钛网下沉的独立危险因素。

Abstract:

BACKGROUND: Anterior subtotal vertebrectomy and fusion using titanium mesh cage (TMC) is an effective surgical treatment for cervical spondylosis, while TMC subsidence usually occurs. The risk factors for TMC subsidence and its effect on the treatment outcomes remain controversial.

OBJECTIVE: To investigate the TMC subsidence after anterior subtotal vertebrectomy and TMC fusion and its effect on the treatment outcomes, thereby understanding the underlying mechanism and related risk factors.
METHODS: Clinical data of 34 patients undergoing anterior subtotal vertebrectomy and TMC fusion in the Second Department of Spine, Shanghai Changzheng Hospital Affiliated to the Second Military Medical University from March to September 2015 were analyzed retrospectively. After 12-month follow-up, the height of the fused segments was measured, and the neurologic outcomes were evaluated using the Japanese Orthopedic Association scores. The loss of the fused segments subsided more than 3 mm compared with that at 1 day postoperatively was considered as TMC subsidence, and all patients were allotted to TMC subsidence and control (without TMC subsidence) groups.
RESULTS AND CONCLUSION: (1) Totally 19 patients (56%) experienced TMC subsidence that occurred in postoperative (6.00±3.73) months averagely. (2) No significant differences were found in the age, sex or the level of fused segments between two groups (P=0.731, 0.672, 0.053). (3) The Japanese Orthopedic Association recovery ratio in the control group was significantly higher than that in the TMC subsidence group (P=0.01), suggesting that TMC subsidence might be correlated with the poor improvement of neurologic function after surgery. (4) To conclude, TMC subsidence is a common complication after anterior subtotal vertebrectomy, which does harm to the treatment outcomes. Moreover, age, sex or the level of fused segments are not independent risk factors for TMC subsidence.
