3D打印人工椎体在脊柱肿瘤全椎体切除术中的疗效评价

目的　分析脊柱肿瘤全椎切除术后应用3D打印人工椎体进行脊柱重建的可行性。方法　选取11例接受脊柱肿瘤全椎切除术并应用3D打印人工椎体进行脊柱重建的患者资料。记录患者手术时间、术中出血量、住院时间、内固定稳定程度,采用视觉模拟评分（VAS）对术前、术后24 h、术后6个月及末次随访的疼痛程度进行评估,并依据日本骨科协会评估治疗分数（JOA）对上述时点脊柱功能进行评估。末次随访时,采用脊髓损伤Frankel分级对脊髓损伤严重程度进行评估,随访期间记录并发症发生情况。结果　全部患者随访8~15个月,平均11个月;患者手术时间（320.21±43.21）min、出血量（1 354.28±101.54）mL、住院时间（22.21±10.24）d。11例患者中10例末次随访时Frankel分级有至少1个等级的改善;所有患者均未出现椎弓根钉位置移动和断裂,假体无脱位。术前、术后24 h及术后6个月的VAS评分呈依次降低趋势（P＜0.01）,但末次随访VAS评分与术后6个月比较差异无统计学意义;除术前与术后24 h JOA评分差异无统计学意义以外,其余各时点JOA评分呈依次升高趋势（P＜0.01）;1例骨巨细胞瘤患者术后3个月复发,1例脊柱继发甲状腺癌患者术后9个月死亡。结论　脊柱肿瘤全椎切除术后应用3D打印人工椎体重建,稳定性高,并发症少,安全性较高,预后良好。

Full-Endoscopic versus Minimally Invasive Lumbar Interbody Fusion for Lumbar Degenerative Diseases : A Systematic Review and Meta-Analysis

ObjectiveAlthough full-endoscopic lumbar interbody fusion (Endo-LIF) has been tried as the latest alternative technique to minimally invasive transforaminal lumbar interobody fusion (MIS-TLIF) since mid-2010, the evidence is still lacking. We compared the clinical outcome and safety of Endo-LIF to MIS-TLIF for lumbar degenerative disease. MethodsWe systematically searched electronic databases, including PubMed, EMBASE, and Cochrane Library to find literature comparing Endo-LIF to MIS-TLIF. The results retrieved were last updated on December 11, 2020. The perioperative outcome included the operation time, blood loss, complication, and hospital stay. The clinical outcomes included Visual analog scale (VAS) of low back pain and leg pain and Oswestry disability index (ODI), and the radiological outcome included pseudoarthosis rate with 12-month minimum follow-up. ResultsFour retrospective observational studies and one prospective observational study comprising 423 patients (183 Endo-LIF and 241 MIS-TLIF) were included, and the pooled data analysis revealed low heterogeneity between studies in our review. Baseline characteristics including age and sex were not different between the two groups. Operation time was significantly longer in Endo-LIF (mean difference [MD], 23.220 minutes; 95% confidence interval [CI], 10.669–35.771; p=0.001). However, Endo-LIF resulted in less perioperative blood loss (MD, -144.710 mL; 95% CI, 247.941–41.478; p=0.023). Although VAS back pain at final (MD, -0.120; p=0.586), leg pain within 2 weeks (MD, 0.005; p=0.293), VAS leg pain at final (MD, 0.099; p=0.099), ODI at final (MD, 0.141; p=0.093) were not different, VAS back pain within 2 weeks was more favorable in the Endo-LIF (MD, -1.538; 95% CI, -2.044 to -1.032; p<0.001). On the other hand, no statistically significant group difference in complication rate (relative risk [RR], 0.709; p=0.774), hospital stay (MD, -2.399; p=0.151), and pseudoarthrosis rate (RR, 1.284; p=0.736) were found. ConclusionRelative to MIS-TLIF, immediate outcomes were favorable in Endo-LIF in terms of blood loss and immediate VAS back pain, although complication rate, mid-term clinical outcomes, and fusion rate were not different. However, the challenges for Endo-LIF include longer operation time which means a difficult learning curve and limited surgical indication which means patient selection bias. Larger-scale, well-designed study with long-term follow-up and randomized controlled trials are needed to confirm and update the results of this systematic review.     

Vertical split fracture of the vertebral body following oblique lumbar interbody fusion: A case report

Rationale:Oblique lumbar interbody fusion (OLIF) is an effective and safe surgical technique widely used for treating spondylolisthesis; however, its use is controversial because of several associated complications, including endplate injury. We report a rare vertebral body fracture following OLIF in a patient with poor bone quality.Patient concerns:A 72-year-old male patient visited our clinic for 2 years with lower back pain, leg radiating pain, and intermittent neurogenic claudication.Diagnoses:Lumbar magnetic resonance imaging revealed L4-5 stenosis.Intervention:We performed OLIF with percutaneous pedicle screw fixation and L4 subtotal decompressive laminectomy. We resected the anterior longitudinal ligament partially for anterior column release and inserted a huge cage to maximize segmental lordosis. No complications during and after the operation were observed. Further, the radiating pain and back pain improved, and the patient was discharged. Two weeks after the operation, the patient visited the outpatient department complaining of sudden recurred pain, which occurred while going to the bathroom. Radiography and computed tomography revealed a split fracture of the L5 body and an anterior cage displacement. In revision of OLIF, we removed the dislocated cage and filled the bone cement between the anterior longitudinal ligament and empty disc space. Further, we performed posterior lumbar interbody fusion L4-5, and the screw was extended to S1.Outcomes:After the second surgery, back pain and radiating pain in the left leg improved, and he was discharged without complications.Lesson:In this case, owing to insufficient intervertebral space during L4-5 OLIF, a huge cage was used to achieve sufficient segmental lordosis after anterior column release, but a vertebral body coronal fracture occurred. In patients with poor bone quality and less flexibility, a huge cage and over-distraction could cause a vertebral fracture; hence, selecting an appropriate cage or considering a posterior approach is recommended.
