RESUMO
Minimally invasive surgery (MIS) is being recommended over more invasive methods. MIS advantages are less time in the operating room, less blood loss, a shorter recovery time, and shorter length of stay. A systematic review and meta-analysis were performed using the literature from minimally invasive and open surgery for adolescent idiopathic scoliosis (AIS). We conducted this analysis to see whether MIS has advantages over traditional surgery. A systematic review was conducted using PubMed, Embase, and Scopus to find articles comparing minimally invasive and open surgery techniques for AIS patients. Data extraction and meta-analysis were completed. The primary data points collected were correction rate and functional outcomes, including perioperative and postoperative parameters. A total of six studies were included in the final analysis. The MIS group had 123 patients, and the open surgery group had 150 patients. The correction rate and functional outcomes favored the open surgery group with a mean difference of 4.60 (95% confidence interval [CI], 0.08 to 9.12) and 0.11 (95% CI, 0.04 to 0.17), respectively. The duration of surgery, blood loss, number of patients requiring transfusion, and analgesic requirements favored the MIS group with a significant difference. Open surgery is better than MIS in achieving a better correction rate and good functional outcomes. MIS is better over open surgery when perioperative parameters are considered.
RESUMO
BackgroundOrthopedic surgical procedures involve a number of aerosol generating procedures; these include electrocautery, power instruments for bone cutting, burring and drilling, and tools for wound lavage. This assumes a great significance in the context of the current COVD-19 pandemic, as there are chances of aerosol-borne disease transmission in orthopedic surgical procedures. Hence, this systematic review and meta-analysis will be undertaken to assimilate and analyse the available evidence on bioaerosols in orthopedic surgical procedures and their significance with respect to SARS-CoV-2 virus transmission. ObjectivesTo determine the characteristics (amount and/or density, size, infectivity, and spread etc.) of bioaerosols found in orthopaedic operating rooms (ORs) and to determine the characteristics of aerosols generated by different orthopaedic power tools and devices. MethodsA systematic review and meta-analysis will be conducted. The PRISMA guidelines will be strictly followed. The primary search will be conducted on the PubMed, EMBASE, Scopus, Cochrane Library, medRxiv, bioRxix and Lancet preprint databases, using a well-defined search strategy. Any original research study (including cohort, case-control, case series, cadaveric studies and studies, animal models, laboratory based experimental studies) looking at aerosol generation in orthopedic surgical procedures, or aerosol generation by orthopaedic power tools and devices will included. Outcome measures will include characteristics (amount and/or density, size, infectivity, and spread etc.) of bioaerosols found in orthopaedic operating rooms (ORs) and those generated by various orthopaedics power tools and devices. Metanalysis using the random-effects model will be conducted to determined pooled estimates of the outcome variables. Heterogeneity will be assessed by the I2 test. Risk of bias will be assessed by the Risk of Bias in Studies estimating Prevalence of Exposure to Occupational risk factors (RoB-SPEO) tool. The overall strength of evidence will be assessed by the GRADE approach.
