Purpose: Postoperative bracing treatment is widely used after surgery for lumbar degenerative diseases. However, the guidelines are lacking in this regard, and its use is mainly driven by individual surgeon preferences. The objective of the current review was to evaluate the available evidence on the use of postoperative bracing after surgery for degenerative disease of the lumbar spine., Methods: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed while conducting a systematic search of the PubMed/Medline, Scopus, and Cochrane databases from January 1990 to January 2019. High-quality studies were included that evaluated disability, pain, quality of life, the rate of fusion, complications, and rate of reoperations in patients who had surgery for lumbar degenerative disease, with and without postoperative bracing. The overall strength of evidence across the studies was assessed using the Grading of Recommendations Assessment, Development, and Evaluation framework., Results: Of the 391 citations screened, four randomized controlled trials met the inclusion criteria and were included in the review. Based on low- to moderate-quality evidence, postoperative bracing in patients with lumbar degenerative disease does not result in improved disability, pain, and quality of life compared to no bracing patients. Low-quality evidence suggests that there was no significant difference between the two groups in terms of the rate of fusion, complications, and the need for reoperation., Conclusions: To date, there is not a medical evidence to support the use of bracing after surgery for lumbar degenerative disease.

We present a case of Zenker's diverticulum in a 45-year-old woman, occurred as complication after anterior cervical discectomy and fusion for a cervical spine injury. The oesophageal complication occurred 12 months after vertebral cervical surgery and presenting symptoms were fever, dysphagia and neck pain with evidence of retropharyngeal infection. We performed a posterior cervical stabilisation C3-D1 by screws and rods and a second anterior left cervical approach with anterior plate removing and oesophageal wall break repairing with a sternohyoid muscle patch. Despite pharyngo-oesophageal diverticulum may be a complication of anterior cervical surgery (traction diverticulum), in case of an already present true Zenker's diverticulum, delayed complication may occur without cervical hardware pull-out., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2018.

Objective: To examine the long-term outcomes (minimum of 4.5 years) of endoscopic endonasal odontoidectomy (EEO) with preservation of anterior C1 ring to treat irreducible ventral bulbo-medullary compressions in rheumatoid arthritis (RA) and to illustrate a novel technique of anterior pure endoscopic craniovertebral junction (CVJ) reconstruction and fusion. In fact, long-term clinical studies are still lacking to elucidate the effective role of EEO and whether it can obviate the need for posterior fixation., Methods: From November 2008 to January 2012, clinical and radiologic data of 7 patients presenting with RA and associated irreducible bulbo-medullary compression treated with EEO were analyzed retrospectively. In all patients, decompression was achieved by EEO with anterior C1 arch preservation. In the last 2 patients, after EEO, we used the spared anterior C1 arch for reconstruction of anterior column of CVJ by positioning, under pure endoscopic guidance, autologous bone and 2 tricortical screws between the anterior arch of C1 and the residual odontoid. All patients were examined clinically with Ranawat classification and radiographically with computed tomography, magnetic resonance imaging, and dynamic radiography immediately after surgery and during follow-up., Results: Adequate bulbo-medullary decompression with anterior C1 arch preservation was obtained in all cases. At follow-up (average, 66.2 months; range, 51-91 months) all patients experienced an improvement at least of one Ranawat classification level and presented no clinical or radiologic signs of instability., Conclusions: EEO with anterior C1 arch sparing provides satisfying long-term results for irreducible ventral CVJ lesions in RA. The preservation of anterior C1 arch and, when possible, the reconstruction of anterior CVJ can prevent the need for posterior fusion., (Copyright © 2017 Elsevier Inc. All rights reserved.)

Until today the role of spinal instrumentation in the presence of a wound infection has been widely discussed and recently many authors leave the hardware in place with appropriate antibiotic therapy. This is a case of a 65-year-old woman suffering from degenerative scoliosis and osteoporotic multiple vertebral collapses treated with posterior dorsolumbar stabilisation with screws and rods. Four months later, skin necrosis and infection appeared in the cranial wound with exposure of the rods. A surgical procedure of debridement of the infected tissue and package with a myocutaneous trapezius muscle flap was performed. One week after surgery, negative pressure wound therapy was started on the residual skin defect. The wound healed after 2 months. The aim of this case report is to focus on the utility of this method even in the case of hardware exposure and infection. This may help avoid removing instrumentation and creating instability., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

Aim: Postoperative surgical site infections (SSI) are complication of spinal surgery. These complications may lead to a poor outcome with neurological deficits, spinal deformity and chronic pain. The purpose of this study is to explore the statistical value of diagnostic parameters and the proper therapy., Method: We retrospectively reviewed 550 patients who underwent spinal instrumentation at our department from January 2011 to December 2015. The SSI was present in 16 patients out of 550 operated. Diagnostic criteria of SSI were the positivity of the surgical wound swab or blood culture, the clinical findings, positivity of laboratory tests and radiological elements. All patients had peri-operative antibiotic prophylaxis. Diagnostic laboratory findings were compared with a homogeneous control group of 16 patients and analyzed by univariate statistical analysis with Chi-square test for the discrete variables. P<0,05 was considered statistically significant., Results: Matching the SSI patients with a group of control, fever was not statistically significant for diagnosis as number of leukocytes, neutrophils and lymphocytes. On the contrary values of ESR and CRP were statistically significant with p <0, 01. The hardware was removed only in 3 patients (18%) out of 16 SSI patients., Conclusion: In this study the statistically significant parameters to diagnose SSI are ESR and CRP values. The leucocytes count, number of lymphocytes and presence of fever integrates the data of ESR and CRP with no statistical significance. Most patients with SSI reach clinical healing with favorable outcome by means of target antibiotic therapy without hardware removal.

Objective: We sought to evaluate the long-term C1-C2 fusion rates, fracture healing, and functional outcomes in geriatric patients with type II odontoid fracture treated with posterior fixation with polyaxial C1 lateral mass screws and C2 pars screws., Methods: Twenty-one consecutive patients between 2005 and 2011 with Anderson and D'Alonzo type II odontoid fracture underwent a posterior atlantoaxial fixation with polyaxial C1 lateral mass screws and C2 pars screws. A long-term clinical and radiologic follow-up was achieved in all patients with a mean follow-up period of 53.28 ± 15.41 months (range 38-91 months)., Results: All 21 patients had bilateral C1 lateral mass screws and bilateral C2 pars screws. Correct positioning of the C1 lateral mass screws and C2 pars screws was observed in all 42 placements by postoperative computed tomography scans. No vascular or neurologic complication was noted. At the last follow-up, 20 patients (95.24%) had a solid fusion (defined as Lenke fusion grade A or B) while 1 patient (4.76%) had a partial fusion (Lenke fusion grade C). Overall, no hardware failures occurred in any patient. Odontoid fracture healing was achieved in 18 patients out of 21 (85.71%). The mean postoperative Neck Disability Index score was 12.73%, and neck motion was within normal physiologic limits at 12 months., Conclusions: This study adds to the evidence that posterior atlantoaxial fixation with polyaxial C1 lateral mass screws and C2 pars screws is a safe and effective surgical option in the treatment of odontoid fractures including long-term stability., (Copyright © 2016 Elsevier Inc.
