Study Design Systematic review and meta-analysis Objectives This study’s objective is to provide a critical review of the current literature regarding the changes in pulmonary function (PF) in Adolescent idiopathic scoliosis (AIS) patients who have undergone posterior spinal fusion and instrumentation (PSF), with and without thoracoplasty (TP). Methods A comprehensive search was performed using the following databases: EMBASE, PubMed, EBSCOhost (CINAHL and Medline) and OpenGrey. Our focus was on studies that compared pre-and postoperative percent-predicted values of forced vital capacity (%FVC) or forced expiratory volume in 1 second (%FEV1) in AIS patients who had undergone PSF, with and without TP, with a minimum 2-year follow-up. The risk of bias for included studies was assessed using the ROBINS-I (“Risk Of Bias In Non-randomised Studies - of Interventions”) tool. Mean change scores were depicted using forest plots. Results Fifteen studies met our inclusion criteria. The results of our analysis suggest that PSF with TP caused a significant deterioration of %FVC in individuals with moderate AIS, with no significant effect on %FEV1. It also showed a minor improvement of FEV1% in individuals with moderate AIS after PSF only, but no significant change in %FVC. Conclusions PSF with TP caused a significant deterioration of % FVC while PSF alone caused a minor improvement of FEV1% in individuals with moderate AIS with a minimum 2-year follow-up.

Background: Early-onset scoliosis (EOS) is frequently associated with complex spine and chest wall deformities that may lead to severe cardiopulmonary impairment and malnutrition. The aim of this study is to evaluate the change in the nutritional status of EOS patients after treatment with magnetically controlled growing rod instrumentation (MCGR) in a single center. Methods: We prospectively collected data of patients treated with MCGR for EOS in a single center. Exclusion criteria were <2 years’ follow-up and incomplete weight-for-age Z-scores (WAZ) data. Preoperative and postoperative WAZ, radiographic parameters, including major coronal curve, kyphosis angle, space available for lung ratios, thoracic height, and unplanned returns to the operating room (UPROR), were analyzed. SD and 95% Confidence intervals (CI) are presented with means. Results: Sixty-eight patients (37 males/31 females) were included. The mean age at surgery was 8.2 years (SD 2.8, range 1.8–14.2), and the mean follow-up time was 3.8 years (SD 1.0, range 2.1–6.8). The study population was categorized by the primary diagnosis as follows: 23 neuromuscular, 18 idiopathic, 15 congenital, and 12 syndromic patients. The major coronal curve improved between the preoperative and latest visits by 40% (P<0.005, SD 27, CI 33–47), while the space available for lung ratios improved by 8% (P<0.005, SD 13, CI 5–12). Thoracic height increased by 25% (P<0.005, SD 13, CI 22–28), and kyphosis angle decreased by 25% (P<0.005, SD 26, CI 9–39). Eighteen patients (27%) required a total of 53 UPRORs. WAZ improved significantly between the preoperative and the latest follow-up (P=0.005). Regression analysis showed WAZ improvements were most significant in the underweight patients and the Idiopathic or Syndromic EOS patients. UPROR was not associated with deterioration in WAZ. Conclusions: Treatment of EOS patients with MCGR resulted in an improvement in nutritional status, as evidenced by the significant increase in WAZ. Underweight, Idiopathic and Syndromic EOS patients, and those who required UPROR all had significant improvement in their WAZ with MCGR treatment. Level of Evidence: Therapeutic Study—Level II.

Objectives Informed consent plays a vital role in managing patients undergoing knee arthroplasty (KA). Unfortunately, patient recall of informed consent remains poor. Evidence has suggested that telemedicine and teleconsent can be safe, cost-effective, and well-received by patients. The primary aim of this study was to evaluate the effect of an additional preoperative teleconsent session on patient recall of surgical risks 1 month after knee arthroplasty. The secondary aim was to assess its impact on patient satisfaction. Methods Sixty adult patients awaiting knee arthroplasty were randomly allocated to receive an additional preoperative teleconsent consultation (intervention group) or not (control group), along with the standard informed consent on the day of surgery. Participants were contacted 1 month after surgery to assess recall of surgical risks and satisfaction with the process. Demographics and education levels were recorded for each patient. Results The mean recall rates were 16% and 12% in the study and control groups, respectively, with no significant difference ( p = 0.42). There was a significant difference between the mean satisfaction scores in the intervention group and the control group (9.8/10 vs 9/10, p = 0.0004). Lastly, there was a significant positive correlation between the education level and the number of risks recalled in the study ( p = 0.05) and control groups ( p = 0.04). Conclusion The additional preoperative teleconsent session had no significant effect on the risk recall rate but improved patient satisfaction. Our findings suggest education level may play a role in information recall. We can advocate for the increased use of teleconsent and telemedicine in patients undergoing KA or any elective orthopaedic procedure due to its perceived positive effects on patient satisfaction rates.
