“…Given that most surgeons verify the deformity correction using intraoperative radiographs, it is crucial to elucidate risk factors for postoperative complications using these radiographs. According to previous studies, frontal plane correction measured using intraoperative supine radiographs is comparable with similar measurements made using the full-length postoperative standing radiographs 17 . Lehman et al 18 have reported that intraoperative prone long-cassette scoliosis film correlated with the immediate postoperative standing film for all curve correction and balance parameters.…”

Background:Incidence of complications and reoperations between pedicle screw (PS) and hybrid instrumentations (HI) are still controversial in adolescent idiopathic scoliosis (AIS) patients. A systematic review and meta-analysis were performed to compare overall complications, reoperations, and radiographic outcomes between the 2 constructs.Methods:Strictly followed the PRISMA 2009 guidelines, the MEDLINE, EMBASE, and the Cochrane Library databases were used to search for literatures up to April 2016, addressing PS versus HI in AIS patients. The Newcastle–Ottawa scale was adopted to assess the quality of the studies. Data on complications, reoperations, Cobb angle of major curve, thoracic kyphosis, and proximal junctional measurement were extracted from the included studies. RevMan 5.3 and SPSS 21.0 were used for statistical analysis.Results:Twenty-four case-control studies with a total of 3042 AIS patients (1582 PS, 1460 HI) were included, consisting of 1 randomized controlled trial, 1 prospective study, and 22 retrospective studies. Decreased overall complications (95% CI 0.42–0.87, P = .007; I2 = 38%) and reoperations (95% CI 0.22–0.62, P = .0001; I2 = 0%) were found in PS group compared with HI group. As regard to reasons for reoperations, increased incidence of pseudarthrosis (P = .005), dislodged instrumentation (P = .005), and deep infection (P = .016) occurred in HI group. PS group achieved a better coronal correction (95% CI −7.06 to −4.54, P < .00001; I2 = 34%), but HI group was more powerful in restoring thoracic kyphosis (95% CI −7.88 to −3.70, P < .00001; I2 = 60%), and no significant differences were found in proximal junctional measurement (95% CI −0.88 to 1.54, P = .59; I2 = 0%) between the 2 constructs.Conclusion:Compared with hybrid instrumentation, pedicle screw construct provides better coronal correction but less thoracic kyphosis restoring, with decreased incidence of overall complications and reoperations in AIS patients. As regard to the pedicle screw construct, the most common reasons for reoperation are malposition, deep infection, pseudarthrosis, and prominent implant.

Most studies have excluded postoperative drain volumes in analyzing blood loss associated with scoliosis surgery. We sought to analyze patient and surgical factors that influenced postoperative drain outputs. A retrospective review was conducted on 50 consecutive patients who had undergone posterior spinal fusion with pedicle screw instrumentation and subfascial drain placement over a 6-year period at a single institution for adolescent idiopathic scoliosis. Postoperative drain volumes were correlated to patient factors, surgical variables, and change in postoperative hemoglobin values. The association between drain output volumes and the need for allogeneic blood transfusion was also analyzed using univariate and multivariate analysis. Total postoperative drain volume positively correlated with Cell Saver volume (r=0.28, P=0.049), units of packed red blood cells transfused intraoperatively (r=0.31, P=0.03), and a number of Ponte osteotomies (r=0.43, P=0.002). On the basis of multiple linear regression analysis, only the number of osteotomies performed was associated with increasing total drain volume (R 2=0.25, P=0.003). Total drain output did not correlate with postoperative change in hemoglobin (P=0.85), the need for postoperative blood transfusion (P=0.22), or the total volume of blood transfused perioperatively (P=0.06). Patients with large intraoperative blood loss or multiple osteotomies are more likely to have higher postoperative drain volumes. Drain volume alone, however, should not be used as a trigger for recommending a postoperative blood transfusion.
