Meta-Analysis Review
BACKGROUND
To compare the clinical outcomes of C laminectomy and C laminoplasty at the C segment during French-door laminoplasty.
METHODS
The Cochrane Library, PubMed, Embase, and Web of Science databases were searched from inception to November 10, 2020 for studies comparing the clinical outcomes of two types of French-door laminoplasty in the treatment of multilevel cervical spondylotic myelopathy (MCSM). Review Manager 5.3 was used to analyze the following outcomes: operative time, intraoperative blood loss, preoperative and postoperative Japanese Orthopaedic Association (JOA) scores, recovery rate, cervical curvature, cervical range of motion (ROM), incidence of axial symptoms (AS), and C bony fusion rate.
RESULTS
A total of eight studies involving 776 patients were included; there were 424 patients in the C laminectomy group and 352 patients in the C laminoplasty group. The results of the meta-analysis showed that the C laminectomy group was superior to the C laminoplasty group in terms of operative time (P < 0.00001), cervical ROM (P = 0.04), and incidence of AS (P < 0.0001). However, no statistically significant differences between the two groups were noted regarding intraoperative bleeding (P = 0.44), preoperative JOA score (P = 0.57), postoperative JOA score (P = 0.09), recovery rate (P = 0.25), cervical curvature (P = 0.22), and C bony fusion rate (P = 0.06).
CONCLUSION
This meta-analysis demonstrated that both C laminoplasty and C laminectomy could effectively improve neurological function in patients with MCSM in French-door laminoplasty. However, C laminectomy can reduce the operative time, preserve cervical ROM, and reduce the incidence of postoperative AS.

Meta-Analysis Review
AIM
This systematic review and meta-analysis evaluated the clinical survival of axial and tilted implants in atrophic edentulous maxilla after three years of immediate loading and also the corresponding marginal bone loss.
SETTING AND DESIGN
This systematic review was conducted in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines (PRISMA).
MATERIALS AND METHODS
The relevant studies were retrieved from MEDLINE(PubMed), the Cochrane Central Register of Controlled Trials (CENTRAL), Science Direct, Google Scholar databases. The search was limited to studies published in the English language with no date restrictions. A further hand search was conducted on individual journals and reference lists of studies. The risk of bias in included studies was assessed by using the Evidence Project risk of bias tool.
STATISTICAL ANALYSIS USED
Statistical meta-analysis was conducted using RevMan 5.4 software. The assessment for the level of evidence was done using GRADEpro software.
RESULTS
Eleven studies were finalised. All were included in the meta-analysis for implant survival, while only seven studies were included in the meta-analysis of marginal bone loss. After three years, the meta-analysis results for implant survival showed no statistical difference between axial and tilted implants, with the forest plot neither favouring axial nor tilted implants (RR = 1.00 (95% CI: 0.98-1.01); P-value = 0.59). After three years, the meta-analysis results for marginal bone showed no statistical difference between axial and tilted implants, with the forest plot neither favouring axial nor tilted implants (MD = -0.02; 95% CI; -0.09-0.06; P-value = 0.69).
CONCLUSION
In the immediately loaded rehabilitation of completely edentulous atrophic maxillae, tilting of implants did not induce any significant alteration in their survival and their corresponding marginal bone loss levels compared to conventionally placed axial implants even after three years of function.

AIM
The aim of this review was to evaluate the survival rate of axial and tilted implants in rehabilitation of edentulous jaws using all on four concept.
SETTING AND DESIGN
Systematic Review.
MATERIALS AND METHODS
A literature review was performed in MEDLINE, PubMed Central (PMC), Google scholar, Embase, Cochrane Central Register of Controlled Trials. Hand searches were conducted of the bibliographic of related journals and systematic reviews. A total of 380 articles were obtained from the intial screening process. Of these articles, 25 articles fulfilled the inclusion criteria. The authors performed evaluation of articles independently as well as data extraction and quality assessment.
STATISTICAL ANALYSIS USED
Qualitative analysis.
RESULTS
The major prosthetic complication was the fracture of the acrylic prosthesis. The mean cumulative survival rate of implants (72-132 months) were 94% to 98%. The prosthesis survival rate (12 months) was between 99% to 100%. The averaged bone loss was 1.3 ±0.4 mm (12-60 months). No Significant difference was found between survival rates of axial and tilted implants nor between maxilla and mandible.
CONCLUSION
All on four concept can be employed successfully in the edentulous patients with resorbed ridges while improving their quality of life and reducing morbidity. However,randomized clinical trials with large sampling size and long term follow up should be incorporated.

Radiographic axial spondyloarthritis (also known as ankylosing spondylitis [AS]) is a chronic immune-mediated arthritis characterized by inflammation of the axial skeleton, peripheral joints, and entheses. It is estimated that 1 in every 200 people are affected by AS, making it an important healthcare and socioeconomic issue. In this review, we aim to explore the current understanding of AS risk factors and provide a comprehensive update. Multiple search strings were used to identify articles of interest published in PubMed between January 1, 2013, and February 1, 2021. On the basis of the literature review and analysis, we present up-to-date information on the risk factors of developing AS and our viewpoints on disease onset and progression. Multiple genetic and nongenetic risk factors have been suggested in the onset of AS. HLA-B27 is known to have a strong association with the disease, but other genes have been implicated in disease development. Aside from genetics, other factors are thought to be involved; up to 70% of patients with AS have subclinical intestinal inflammation, suggesting that the origin of the disease may be in the gut. The exact mechanism by which AS onset begins is most likely complex and multifactorial. Key Points • It remains unclear how interactions between genes, microbes, mechanical stress, gender, and other environmental and lifestyle factors predispose patients to the development of ankylosing spondylitis (AS). • The exact mechanisms of AS are complex and multifactorial which will require much future research • Recognizing the risk factors, as well as understanding gene-environment interactions, may offer valuable insights into the etiology of AS and have important implications for diagnosis and treatment strategies.

Meta-Analysis
For spinal load and muscle force estimation as well as for numerical model and experimental setup validation, data on human intradiscal pressure are essential. Therefore, the aim of the present meta-analysis was to summarise all in vitro measurements of human intradiscal pressure performed under defined boundary conditions, i.e. without external loading (intrinsic pressure), under axial loading (compression, traction, shear) and under single-planar bending loading (flexion, extension, lateral bending, axial rotation). Data were evaluated based on segmental level and normalised to force and moment. Regression analysis was performed to investigate coefficients of determination and statistical significance of relationships between intradiscal pressure and segmental level for the single loading conditions. 35 studies fulfilled the inclusion criteria, from which a total of 451 data points were collected for the meta-analysis. High coefficients of determination were found in axial compression (r2 = 0.875) and flexion (r2 = 0.781), while being low for intrinsic pressure (r2 = 0.266) and lateral bending (r2 = 0.385), all showing significant regression fitting (p < 0.01). Intradiscal pressure decreases from the upper cervical spine to the sacrum in all loading conditions, considering the same amount of loading for all segmental levels, while the intrinsic pressure exhibits a minimum of the regression curve in the mid-thoracic spine. Apart from its potential for numerical and experimental model validation, this dataset may help to understand the load distribution along the human spine.

Meta-Analysis Review
Despite being a common procedure, cranioplasty (CP) is associated with a variety of serious, at times lethal, complications. This study explored the relationship between the initial injury leading to decompressive craniectomy (DC) and the rates and types of complications after subsequent CP. It specifically compared between traumatic brain injury (TBI) patients and patients undergoing CP after DC for other indications.A comprehensive search of PubMed, Scopus, and the Cochrane Library databases using PRISMA guidelines was performed to include case-control studies, cohorts, and clinical trials reporting complication data for CP after DC. Information about the patients' characteristics and the rates of overall and specific complications in TBI and non-TBI patients was extracted, summarized, and analyzed.A total of 59 studies, including the authors' institutional experience, encompassing 9264 patients (4671 TBI vs. 4593 non-TBI) met the inclusion criteria; this total also included 149 cases from our institutional series. The results of the analysis of the published series are shown both with and without our series 23 studies reported overall complications, 40 reported infections, 10 reported new-onset seizures, 13 reported bone flap resorption (BFR), 5 reported post-CP hydrocephalus, 10 reported intracranial hemorrhage (ICH), and 8 reported extra-axial fluid collections (EFC). TBI was associated with increased odds of BFR (odds ratio [OR] 1.76, p < 0.01) and infection (OR 1.38, p = 0.02). No difference was detected in the odds of overall complications, seizures, hydrocephalus, ICH, or EFC.Awareness of increased risks of BFR and infection after CP in TBI patients promotes the implementation of new strategies to prevent these complications especially in this category of patients.

Meta-Analysis
OBJECTIVES
Magnetic resonance imaging (MRI) is currently the most accurate imaging tool used in axial spondyloarthritis regarding its diagnostic approach. MRI of the spine and sacroiliac joints (SIJ) might be relevant in the follow-up of axial spondyloarthritis for difficult cases, provided that its validity and correlation with clinical, biological and functional outcomes is ascertained. The aim of this study was to assess the effect of TNF alpha inhibitors (TNFi) on MRI scoring of inflammation on spine and SIJ and to evaluate their correlation with the parameters used in daily practice.
METHODS
A systematic review of the literature using PUBMED and the Cochrane library was performed until January 2016. All randomised controlled trials and controlled cohorts reporting the effect of TNFi on spine and SIJ MRI scores [Ankylosing Spondylitis spine MRI (ASspiMRI), Spondyloarthritis Research Consortium of Canada (SPARCC), and Berlin] were selected. The collected outcomes were: the change in scores between baseline and follow-up in TNFi and control groups, the correlation of these changes with C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), Bath Ankylosing Spondylitis Disease Activity Index/Functional Index (BASDAI/BASFI), Ankylosing Spondylitis Disease Activity Score (ASDAS), pain and morning stiffness. When appropriate, statistical analysis determined the pooled therapeutic effect of TNFi on MRI scores computed by meta-analysis.
RESULTS
Of 39 screened references, 55 studies were included. In studies using ASspiMRI at 12-week and 2-year follow-up, and in those using SPARCC spine score at 12-week follow-up, a non-significant decrease in MRI score between the TNFi group and control group was reported (p=0.36; p=0.73; p=0.12, respectively). Only a significant decrease in the SPARCC SIJ score was reported at 12 weeks in the TNFi group versus control (p<0.0001). The correlation between MRI spine and SIJ scores on the one hand, and the clinical and biological data on the other was very heterogeneous across the different reports. However, an association was usually reported between the MRI scores and CRP, ESR and ASDAS.
CONCLUSIONS
There is not sufficient evidence to distinguish the difference between changes in MRI inflammatory lesions of the spine and SIJ in patients with axial SpA related to TNF alpha inhibitor effects and those due to the natural course of the disease activity (alternating periods of flares and remission in axial SpA).

Review
Patients with sarcoma experience many physical and psychological symptoms, adversely affecting their health-related quality of life (HRQoL). HRQoL assessment is challenging due to the diversity of the disease. This review aims to unravel the heterogeneity of HRQoL of patients with sarcoma with regard to tumour location and to summarise the used measures in research. English-language literature from four databases published between January 2000 and April 2019 was reviewed. Studies that described adult sarcoma HRQoL outcomes were included and classified according to primary sarcoma location. Eighty-seven articles met the inclusion criteria covering sarcoma of the extremities (n=35), pelvis and axial skeleton (n=9), pelvis and extremities (n=5), head and neck (n=4), retroperitoneum (n=2) and multiple sarcoma locations (n=33), respectively. Urogenital and thoracic sarcoma were lacking. Fifty-four different questionnaires were used, most often cancer-generic or generic HRQoL questionnaires. Patients with sarcoma reported lower HRQoL than the general population. Distinctive patterns of HRQoL outcomes according to tumour location regarding symptoms, physical functioning, disability and psychosocial well-being were identified. In metastatic sarcoma, mostly constitutional symptoms were present. To comprehensively assess HRQoL, a sarcoma-specific measurement strategy should be developed and used covering the heterogeneity of sarcoma including location-specific issues to improve personalised HRQoL assessment in future research and clinical practice.

Meta-Analysis Review
BACKGROUND
Axial spondyloarthropathy (axSpA) is an inflammatory arthritis which affects the sacroiliac joints and the spine. Many females affected are of childbearing age. Studies on effects of pregnancy on axSpA disease activity and medication use have been limited, with divergent conclusions.
OBJECTIVE
To review literature on axSpA in pregnancy to determine the effect of disease on pregnancy outcomes.
METHODS
A systematic review of case-control trials, observational studies, cross sectional studies and case series (n>5) on axSpA in pregnancy. EMBASE, Medline (OVID), CINAHL, Maternity and Infant Care (MIDIRS online), and Web of Science were searched for keywords. Two reviewers reviewed articles to determine suitability for inclusion. The Newcastle Ottawa Scale was used to assess risk of bias. Data extraction was performed using a standardized template to streamline data to allow comparison and meta-analysis.
RESULTS
Search strategy returned 884 records, 130 full text articles were assessed for eligibility. Eighteen studies with a total of 3,166 axSpA participants were eligible for inclusion. There was an increased prevalence of pre-eclampsia (OR 1.3, 95% CI 0.92-1.82) and IUGR (OR 1.17, 95% CI 0.26-5.17) and a statistically significant increase in cesarean sections (OR 1.85, 95% CI 1.46-2.30) in axSpA females, with an especially high prevalence of elective cesarean sections (OR 2.26, 95% CI 1.74, 2.93). There was a trend towards increased prevalence of fetal complications in axSpA pregnancies (LBW OR 1.47, 95% CI 0.98-2.21; SGA OR1.66, 95% CI 0.93-2.95; congenital abnormalities OR 1.34, 95% CI0.63-1.24; NICU admissions OR 1.55, 95% CI 0.96-2.51) which did not reach significance.
CONCLUSION
AxSpA females have an increased prevalence of cesarean sections compared to the general population. There is a trend towards increased prevalence of pre-eclampsia, IUGR and certain fetal complications. Ongoing development of national registries could help to better understand axSpA in pregnancy.

Review
OBJECTIVES
Ankylosing spondylitis (AS) is a chronic rheumatic disease which affects the axial skeleton and sacroiliac joints. By impacting spinal mobility and physical functions, AS could also potentially impair gait. However, while published data are rather sparse, it appears that discrepancies exist regarding AS consequences on gait characteristics, tasks and analysis techniques used to assess gait ability of patients with AS. The review questions are twofold: (1) How is gait assessed in patients with AS? and (2) What are the consequences of AS on gait?
METHODS
Databases were systematically searched to identify studies satisfying the search criteria, using the synonyms of ankylosing spondylitis and gait. Two reviewers extracted from the articles study characteristics, methods and main results in relation to gait.
RESULTS
192 titles were extracted from databases and 21 studies were included in the review. 16 studies (76%) used clinical gait measurements and 5 (23%) used laboratory gait measurements. Only 7 involved a healthy control group. Studies used various protocols, instructions and parameters when assessing gait. Gait of patients with AS was associated with decreased stride length, pelvic movements and lower limbs angles in the sagittal plane, and increased hip abduction and external rotation compared to healthy controls.
CONCLUSIONS
Only few studies have assessed gait characteristics in patients with AS and published data evidence that kinematic parameters of gait is altered, but no consensus exists regarding gait analysis methods for patients with AS. Guidelines are provided to improve the design and methodology for future studies on gait and AS.
