Study Design: Systematic review. Objectives: There is paucity of consensus on whether (1) the artery of Adamkiewicz (AoA) and (2) the number of contiguous segmental spinal arteries (SSAs) that can be safely ligated without causing spinal cord ischemia. The objective of this review is to determine the risk of motor neurological deficits from iatrogenic sacrifice of the (1) AoA and (2) its vicinity’s SSAs. Methods: Systematic review of the spine and vascular surgery was carried out in accordance to PRISMA guidelines. Outcomes in terms of risk of postoperative motor neurological deficit with occlusion of the AoA, bilateral contiguous SSAs, or unilateral contiguous SSAs were analyzed. Results: Ten articles, all retrospective case series, were included. Three studies (total N = 50) demonstrated a postoperative neurological deficit risk of 4.0% when the AoA is occluded. When 1 to 6 pairs of SSAs (without knowledge of AoA location) were ligated, the postoperative neurological deficit risk was 0.6%, as compared with 5.4% when more than 6 bilateral pairs of SSAs were ligated (relative risk [RR] = 0.105, 95% CI 0.013-0.841, P = .0337). For unilateral ligation of SSAs of two to nine levels, the risk of postoperative neurological deficit does not exceed 1.3%. Conclusion: The current best evidence indicates that (1) occlusion of the AoA and (2) occlusion of up to 6 pairs of SSAs is associated with a low risk of postoperative neurological deficit. This limited number of low quality studies restrict the ability to draw definitive conclusions. Ligation of AoA and SSAs should only be undertaken when absolutely required to mitigate the small but devastating risk of paralysis.

Study Design: Retrospective case series; systematic review. Objective: It is unknown whether the use of virtual surgical planning (VSP) to facilitate same-admission microsurgical reconstruction of the mandible following acute maxillofacial ballistic trauma (MBT) is sufficient to achieve definitive reconstruction and functional occlusion. Methods: A single-center retrospective analysis was conducted for patients who underwent microsurgical reconstruction of the mandible using VSP after acute MBT. The PubMed/MEDLINE, Embase, ScienceDirect, and Scopus databases were systematically reviewed using blinded screening. Studies were evaluated via thematic analysis. Results: Five patients were treated by same-admission and microsurgical reconstruction of the mandible using VSP. We observed an average of 16.4 ± 9.1 days between initial presentation and reconstruction, an average length of stay of 51.6 ± 17.9 days, 6.2 ± 2.8 operations, and 1.6 ± 0.9 free flaps per patient. Four types and 8 total flaps were employed, most commonly the anterior lateral thigh flap (37.5%). Care yielded complete flap survival. Each patient experienced at least 1 minor complication. All patients achieved centric occlusion, oral nutrition, and an approximation of their baseline facial aesthetic. Follow up was 191.0 ± 183.9 weeks. Systematic review produced 8 articles that adhered to inclusion criteria. Consensus themes in the literature were found for clinical goal and function of VSP when practicing MBT reconstruction, yet disagreement was found surrounding optimal treatment timeline. Conclusions: Same-admission microsurgical reconstruction after MBT is safe and effective to re-establish mandibular form and function. VSP did not delay reconstruction, given the need for preparation prior to definitive reconstruction.

Study Design: Retrospective case-control study. Objective: Neurological deficit is one of the dreaded complications of kyphotic deformity correction procedures. There is inconsistency in the reports of neurological outcomes following such procedures and only a few studies have analyzed the risk factors for neurological deficits. We aimed to analyze the factors associated with neurological deterioration in severe kyphotic deformity correction surgeries. Methods: We performed a retrospective study of 121 consecutive surgically treated severe kyphotic deformity cases (49 males, 56 females) at a single institute (May 1st 2008 to May 31st 2018) and analyzed the risk factors for neurological deterioration. The demographic, surgical and clinical details of the patients were obtained by reviewing the medical records. Results: 105 included patients were divided into 2 groups: Group A (without neurological deficit) with 92 patients (42 males, 50 females) and Group B (with neurological deficit) with 13 patients (7 males, 6 females) (12.4%). Statistically significant difference between the 2 groups was observed in the preoperative sagittal Cobbs angle (p < 0.0001), operative time (p = 0.003) and the presence of myelopathic signs on neurological examination (p = 0.048) and location of the apex of deformity (p = 0.010) but not in other factors. Conclusions: Preoperative Sagittal Cobbs angle, presence of signs of myelopathy, operative time and location of apex in the distal thoracic region were significantly higher in patients with neurological deterioration as compared to those without neurological deterioration during kyphotic deformity correction surgery. Distal thoracic curve was found to have 4 times more risk of neurological deterioration compared to others.

Introduction: Acute aortic dissection (AAD) is difficult to diagnose and if missed carries a significant mortality rate. Our aim was to assess the accuracy of history, physical exam and plain radiographs compared to advanced imaging in the diagnosis of AAD in adults presenting to the ED with a clinical suspicion of AAD. Methods: We conducted a librarian assisted systematic review. Databases searched: Pubmed, Medline, Embase and the Cochrane database from 1968 to January 2016. No restrictions for language were imposed. Studies were reviewed and data extracted by two independent reviewers. AAD was defined by CTA, MRI or TEE Prospective and retrospective studies of patients presenting with a clinical suspicion of AAD were included. Case series were excluded. Studies were combined if low clinical and statistical heterogeonity (I2<30%). Study quality was assessed using the QUADAS tool. Bivariate random effects meta analyses using Revman 5 and SAS 9.3 was performed. Results: We identified 792 records: 61 selected for full text review, 13 included and a further 7 from reference searches. 20 studies with 4721 participants were included (mean QUADAS score 12/14 SD 1.2, Kappa 0.8). Prevalence of AAD ranged from 9.6-76.1% (mean 39.1% SD 17.1%). Mean diagnosis in those without AAD varied between studies with ACS (30.3% SD 30.1%), Anuerysm(12.4% SD 9.8%), Chest wall pain(18.1% SD 13.3%) and PE(7.9% SD 7.85%) being the most common. The clinical findings most suggestive of AAD were, neurological deficit (specificity 94% LR 4.1 [95% CI, 3.1-5.2], I2 0%, n=9), hypotension(specificity 94% LR 2.6 [95% CI 1.6-4.2], I2 0%, n=8), pulse deficit (specificity 92% LR 3.4 [95% CI 1.8-6.4], I2 0%, n=9) and syncope (specificity 92% LR 1.4 [95% CI 1.1-1.8], I2 10%, n=6). The most useful for identifying patients less likely to have AAD were an absence of a widened mediastinum (sensitivity 80% LR 0.3 [95% CI 0.2-0.5], I2 20%, n=13) and an AHA Aortic dissection risk score <1 (n=2 sensitivity 91%,99% LR 0.02,0.22, [95% CI 0.003-0.128, 95%CI 0.2-0.3]). Conclusion: Suspicion for AAD should be raised with syncope, hypotension and pulse or neurological deficit in the appropriate clinical setting. Conversely the absence of a widened mediastinum and a low ADD score decreases likelihood. Clinical exam alone cannot rule out acute aortic dissection but it can help risk stratify for further testing.

AbstractObjective:A systematic review was performed to evaluate the role and effectiveness of head bandages after routine elective middle-ear surgery.Methods:Studies that compared the effectiveness of head bandage use after elective middle-ear surgery (e.g. myringoplasty, mastoidectomy and cochlear implantation) were identified using the following databases: Ovid Medline and Embase, the Ebsco collections, the Cochrane Library, PubMed, and Google Scholar. An initial search identified 71 articles. All titles and abstracts were reviewed. Thirteen relevant articles were inspected in more detail; of these, only five met the inclusion criteria. These included three randomised, controlled trials, one retrospective case series and one literature review.Results:The three randomised, controlled trials (level of evidence 1b) showed no statistically significant differences in post-operative outcomes (in terms of complications) associated with head bandage use in middle-ear surgery. This finding was supported by the retrospective case series involving patients undergoing cochlear implantation.Conclusion:Current available evidence shows no advantage of head bandage use after middle-ear surgery. Head bandages may not be required after routine, uncomplicated middle-ear surgery.

Knee Pathology

Background: Osgood-Schlatter disease (OSD) is a sport- and growth-associated knee pathology with painful osteochondrosis around the tibial tuberosity. Up to 10% of adolescents are affected by OSD. Treatment is primarily conservative or non-operative and includes injections, ice, braces, casts, tape and/or physiotherapy. However, treatment outcomes are often insufficiently described and there is lack of evidence for current best practice.Objective: The aims of this systematic review are to comprehensively identify conservative or non-operative treatment options for OSD, to compare their effectiveness in selected outcomes, and to describe potential research gaps. and to describe potential research gaps.Methods: This systematic review was conducted according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement. CENTRAL, CINAHL, EMBASE and MEDLINE via Ovid, and PEDro were searched through to January 6, 2020. In addition, ongoing and unpublished clinical studies, dissertations, and other grey literature on OSD were retrieved. We included prospective, retrospective, case control, randomised, and non-randomised studies reporting on the effectiveness of any conservative or non-operative treatment of 6- to 28-year-old OSD patients. Studies written in English, German, or French were included. The quality of the included studies was assessed using the PEDro scale and extracted outcome data were narratively synthesized. In addition, we also systematically retrieved review articles for extraction of treatment recommendations.Results: Of 767 identified studies, thirteen were included: two randomised controlled trials (RCTs), two prospective and eight retrospective observational studies, and one case series. Eight studies had no control group. The included studies were published from 1948 to 2019 and included 747 patients (563 male, 119 female, 65 sex not reported) with 937 affected knees. The study quality was poor to moderate. The two included RCTs examined the effectiveness of surplus dextrose-injection in OSD patients treated with local anaesthetics injection and came to opposite conclusions. Other than that, inter-study heterogeneity prohibited any descriptive cumulative analyses. Among the 15 review articles, the most prevalent treatment recommendations were activity modification (15/15), quadriceps and hamstring stretching (13/15), medication (11/15), ice (11/15), strengthening of the quadriceps (9/15), and knee straps or brace (8/15).Conclusion: Conflicting evidence exists to support the use of dextrose injections. Certain therapeutic approaches, such as stretching, seem to work, but no RCT comparing specific exercises with sham or usual care treatment exists. Carefully controlled studies on well- described treatment approaches are needed to establish which conservative or non-operative treatment options are most effective for patients with OSD.

Abstract Background The mainstay of the treatment for desmoid-type fibromatoses has been shifting from surgery to drug treatment, making accurate prediction of the efficacy of drug treatment of extreme importance. On the other hand, desmoid-type fibromatoses arise everywhere in the body. The purpose of this systematic review was to address the clinical question of whether tumour location has an impact on the efficacy of drug treatment. Methods A literature search from January 1990 to August 2017 was conducted. Four reviewers independently assessed and screened the literature for eligibility and determined the final articles. They rated each report according to the Grading of Recommendations Development and Evaluation approach. Based on the quality of ‘Body of Evidence’, our clinical guideline committee developed a recommendation for the clinical question. Results In total, 128 articles were extracted. After the screenings, 5 were chosen for the final evaluation. The drugs used in these articles were one each of toremifene, sorafenib, and methotrexate and vinblastine and of meloxicam. There were no randomized controlled trials, and two prospective and three retrospective case series were included. Therapeutic effects were observed slightly more markedly in extremity using meloxicam or methotrexate and vinblastine. In contrast, the efficacy of toremifene was slightly higher in non-extremity. However, the evidence level of all of the reports was judged to be low. Conclusions Considering the low evidence level, we concluded that the site-specific therapeutic effects of drugs could not be confirmed in desmoid-type fibromatoses.

OBJECT Minimally invasive transforaminal lumbar interbody fusion (MI-TLIF) and lateral lumbar interbody fusion (LLIF) are 2 currently popular techniques for lumbar arthrodesis. The authors compare the total risk of each procedure, along with other important complication outcomes. METHODS This systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Relevant studies (up to May 2015) that reported complications of either MI-TLIF or LLIF were identified from a search in the PubMed database. The primary outcome was overall risk of complication per patient. Secondary outcomes included risks of sensory deficits, temporary neurological deficit, permanent neurological deficit, intraoperative complications, medical complications, wound complications, hardware failure, subsidence, and reoperation. RESULTS Fifty-four studies were included for analysis of MI-TLIF, and 42 studies were included for analysis of LLIF. Overall, there were 9714 patients (5454 in the MI-TLIF group and 4260 in the LLIF group) with 13,230 levels fused (6040 in the MI-TLIF group and 7190 in the LLIF group). A total of 1045 complications in the MI-TLIF group and 1339 complications in the LLIF group were reported. The total complication rate per patient was 19.2% in the MI-TLIF group and 31.4% in the LLIF group (p < 0.0001). The rate of sensory deficits and temporary neurological deficits, and permanent neurological deficits was 20.16%, 2.22%, and 1.01% for MI-TLIF versus 27.08%, 9.40%, and 2.46% for LLIF, respectively (p < 0.0001, p < 0.0001, p = 0.002, respectively). Rates of intraoperative and wound complications were 3.57% and 1.63% for MI-TLIF compared with 1.93% and 0.80% for LLIF, respectively (p = 0.0003 and p = 0.034, respectively). No significant differences were noted for medical complications or reoperation. CONCLUSIONS While there was a higher overall complication rate with LLIF, MI-TLIF and LLIF both have acceptable complication profiles. LLIF had higher rates of sensory as well as temporary and permanent neurological symptoms, although rates of intraoperative and wound complications were less than MI-TLIF. Larger, prospective comparative studies are needed to confirm these findings as the current literature is of relative poor quality.

Study Design: A retrospective case-control study. Objectives: The usefulness of a drain in spinal surgery has always been controversial. The purposes of this study were to determine the incidence of hematoma-related complications after posterior lumbar interbody fusion (PLIF) without a drain and to evaluate its usefulness. Methods: We included 347 consecutive patients with degenerative lumbar disease who underwent single- or double-level PLIF. The participants were divided into 2 groups by the use of a drain or not; drain group and no-drain group. Results: In 165 cases of PLIF without drain, there was neither a newly developed neurological deficit due to hematoma nor reoperation for hematoma evacuation. In the no-drain group, there were 5 (3.0%) patients who suffered from surgical site infection (SSI), all superficial, and 17 (10.3%) patients who complained of postoperative transient recurred leg pain, all treated conservatively. Days from surgery to ambulation and length of hospital stay (LOS) of the no-drain group were faster than those of the drain group ( P < 0.001). In a multiple regression analysis, a drain insertion was found to have a significant effect on the delayed ambulation and increased LOS. No significant differences existed between the 2 groups in additional surgery for hematoma evacuation, or SSI. Conclusions: No hematoma-related neurological deficits or reoperations caused by epidural hematoma and SSI were observed in the no-drain group. The no-drain group did not show significantly more frequent postoperative complications than the drain use group, hence the routine insertion of a drain following PLIF should be reconsidered carefully.

AimTo investigate clinical characteristics, risk factors (RFs), neurologic deficits and medical care provided in children who had a stroke in China.MethodsWe conducted a retrospective case-series study using the medical records of children aged 1 month to 18 years with arterial ischaemic stroke (AIS) or haemorrhagic stroke (HS) (with the entry codes I60, I61, I62, I63 (ICD-10)), who were admitted to different hospitals in Beijing, between January 2018 and December 2018. We obtained the following information from the charts: demographic characteristics, clinical presentations, RFs for paediatric stroke, laboratory examination, neuroimaging records and neurologic sequelae.ResultsWe identified 312 first admissions for stroke (172 AIS and 140 HS). The mean age at onset was 8.6±3.9 years for patients who had an AIS and 8 (5–13) years for patients who had an HS. There were more males than females in both groups (AIS: 59.88% vs 40.12%; HS: 52.14% vs 47.86%). A known aetiology was identified in 92.44% and 86.43% of patients who had an AIS and HS, respectively. The leading cause of AIS was cerebrovascular diseases including moyamoya (68.6%), while that for HS was arteriovenous malformation (51.43%). The most common initial clinical presentation was hemiplegia (86.05%) in patients who had an AIS and headache (67.86%) in patients who had an HS. The use of healthcare, including acute treatment (antithrombotic in 17.44%, anticoagulant in 5.23%) and secondary prevention (antithrombotic in 6.39%, anticoagulant in 1.16%), varied and was significantly lower among patients who had an AIS. The most common complications were epilepsy (22.09%) and pneumonia (4.65%) in patients who had an AIS and epilepsy (17.14%) and hydrocephalus (12.14%) in patients who had an HS. Neurological deficits occurred in 62.8% of patients who had an AIS and 72.86% of patients who had an HS.ConclusionCerebral arteriopathy was a major RF for both AIS and HS in children living in China. Large epidemiological studies are required to identify RFs to prevent stroke as well as appropriate interventions.
