Background: Morbidity can be high in the management of adult spinal deformity patients. Complications include blood loss (EBL), durotomy, radicular pain, and postoperative hardware failure. Utilization of one versus two spinal surgeons in spinal deformity correction reduces overall perioperative morbidity is unclear. Methods: All procedures were performed by surgeons at a single institution between January 2012-2015. Patients were followed for a minimum of one year and maximum of four years. We retrospectively reviewed 60 cases of adult spinal deformity. Our cohort was divided into 1 versus 2 surgeons (12 vs 48 cases). We analyzed these cases for estimated blood loss and peri-operative complications. Results: Cases involving long thoracic to pelvis correction (T3-T6) was 20.8% in the 2 surgeons group and 8.3% in the 1 surgeon group. The EBL >3.0 L for 1 versus 2 surgeon groups were 25% and 41.6% respectively. Major complications in the 1 versus 2 surgeon group were 25% and 47.9% and the revision rates were 25% versus 37.5%. The percentage of minor complications in the 1 versus 2 surgeon group was 33.3% versus 14.6%. Conclusions: Utilizing two surgeons did not reduce complication rates. Procedures performed by two surgeons were more extensive deformity corrections. The extent of correction is the likely explanation for differing complication rates.

OBJECTIVESpinal deformity causing spinal imbalance is directly correlated to pain and disability. Prior studies suggest adult spinal deformity (ASD) patients with rheumatoid arthritis (RA) have more complex deformities and are at higher risk for complications. In this study the authors compared outcomes of ASD patients with RA following thoracolumbar 3-column osteotomies to outcomes of a matched control cohort.METHODSAll patients with RA who underwent 3-column osteotomy for thoracolumbar deformity correction performed by the senior author from 2006 to 2016 were identified retrospectively. A cohort of patients without RA who underwent 3-column osteotomies for deformity correction was matched based on multiple clinical factors. Data regarding demographics and surgical approach, along with endpoints including perioperative outcomes, reoperations, and incidence of proximal junctional kyphosis (PJK) were reviewed. Univariate analyses were used to compare patients with RA to matched controls.RESULTSEighteen ASD patients with RA were identified, and a matched cohort of 217 patients was generated. With regard to patients with RA, 11.1% were male and the mean age was 68.1 years. Vertebral column resection (VCR) was performed in 22.2% and pedicle subtraction osteotomy (PSO) in 77.8% of patients. Mean case length was 324.4 minutes and estimated blood loss (EBL) was 2053.6 ml. Complications were observed in 38.9% of patients with RA and 29.0% of patients without RA (p = 0.380), with a trend toward increased medical complications (38.9% vs 21.2%, p = 0.084). Patients with RA had a significantly higher incidence of deep vein thrombosis (DVT)/pulmonary embolism (PE) (11.1% vs 1.8%, p = 0.017) and wound infections (16.7% vs 5.1%, p = 0.046). PJK occurred in 16.7% of patients with RA, and 33.3% of RA patients underwent reoperation. Incidence rates of PJK and reoperation in matched controls were 12.9% and 25.3%, respectively (p = 0.373, p = 0.458). At follow-up, mean sagittal vertical axis (SVA) was 6.1 cm in patients with RA and 4.5 cm in matched controls (p = 0.206).CONCLUSIONSFindings from this study suggest that RA patients experience a higher incidence of medical complications, specifically DVT/PE. Preoperative lower-extremity ultrasounds, inferior vena cava (IVC) filter placement, and/or early initiation of DVT prophylaxis in RA patients may be indicated. Perioperative complications, morbidity, and long-term outcomes are otherwise similar to non-RA patients.

Abstract Background Although excellent clinical outcomes of supercapsular percutaneously assisted total hip arthroplasty (SuperPath) have been reported, the peri-operative blood loss has rarely been reported. The current study determined the blood loss during SuperPath and compared the blood loss with conventional posterolateral total hip arthroplasty (PLTH). Methods This retrospective study enrolled patients who underwent unilateral primary THA between January 2017 and December 2019. The demographic data, diagnoses, affected side, radiographic findings, hemoglobin concentration, hematocrit, operative time, transfusion requirements, and intra-operative blood loss were recorded. The peri-operative blood loss was calculated using the OSTHEO formula. Blood loss on the 1st, 3rd, and 5th post-operative days was calculated. Hidden blood loss (HBL) was determined by subtracting the intra-operative blood loss from the total blood loss. Results Two hundred sixty-three patients were included in the study, 85 of whom were in the SuperPath group and 178 in the posterolateral total hip arthroplasty (PLTH) group. Patient demographics, diagnoses, affected side, operative times, and pre-operative hemoglobin concentrations did not differ significantly between the two groups (all P > 0.05). Compared to the PLTH group, the SuperPath group had less blood loss, including intra-operative blood loss, 1st, 3rd, and 5th post-operative days blood loss, and HBL (all P < 0.05). Total blood loss and HBL was 790.07 ± 233.37 and 560.67 ± 195.54 mL for the SuperPath group, respectively, and 1141.26 ± 482.52 and 783.45 ± 379.24 mL for the PLTH group. PLTH led to a greater reduction in the post-operative hematocrit than SuperPath (P < 0.001). A much lower transfusion rate (P = 0.028) and transfusion volume (P = 0.019) was also noted in the SuperPath group. Conclusion SuperPath resulted in less perioperative blood loss and a lower transfusion rate than conventional PLTH.

Abstract The purpose of this study was to determine the feasibility and clinical benefits of using 3D-printed hemipelvis models for periacetabular osteotomy preoperative planning in the treatment of hip dysplasia. This retrospective study included 28 consecutive cases in 26 patients, with two bilateral cases, who underwent periacetabular osteotomy between January 2017 and February 2020 and had routine radiographs, CT and MR imaging. Of these, 14 cases [mean patient age 30.7 (SD 8.4) years, 11 female] had routine preoperative imaging, and 14 cases [mean patient age 28.0 (SD 8.7) years, 13 female] had routine preoperative imaging and creation of a full-scale 3D-printed hemipelvis model from the CT data. The expected surgical cuts were performed on the 3D-printed models. All patients underwent Bernese periacetabular osteotomy. Operative times, including time to achieve proper acetabular position and total periacetabular osteotomy time, fluoroscopy radiation dose and estimated total blood loss were compiled. ANOVA compared outcome variables between the two patient groups, controlling for possible confounders. On average, patients who had additional preoperative planning using the 3D-printed model had a 5.5-min reduction in time to achieve proper acetabular position and a 14.5-min reduction in total periacetabular osteotomy time; however, these changes were not statistically significant (P = 0.526 and 0.151, respectively). No significant difference was identified in fluoroscopy radiation dose or total blood loss. Detailed surgical planning for periacetabular osteotomy using 3D-printed models is feasible using widely available and affordable technology and shows promise to improve surgical efficiency.

Background Previous studies and meta analyses have led to incongruent and incomplete results respectively when total intravenous anesthesia (TIVA) and inhalational anesthesia (IA) are compared in endoscopic sinus surgeries in regards to intraoperative bleeding and visibility. Objective To perform a more comprehensive meta-analysis on randomized controlled trial (RCTs) comparing TIVA with IA in endoscopic sinus surgery to evaluate their effects on intraoperative bleeding and visibility. Methods A systematic review and meta-analysis of studies comparing TIVA and IA in endoscopic sinus surgery for chronic rhinosinusitis was completed in May 2020. Utilizing databases, articles were systematically screened for analysis and 19 studies met our inclusion criteria. The primary outcome included intraoperative visibility scores combining Boezaart, Wormald and Visual Analogue Scale (VAS). Secondary outcomes included rate of blood loss (mL/kg/min), estimated total blood loss (mL), Boezaart, Wormald scores, VAS, heart rate, and mean arterial pressure (MAP). Results 19 RCTs with 1,010 patients were analyzed. TIVA had a significantly lower intraoperative bleeding score indicating better endoscopic visibility (Boezaart, VAS, and Wormald) than IA (−0.514, p = 0.020). IA had a significantly higher average rate of blood loss than TIVA by 0.563 mL/kg/min (p = 0.016). Estimated total blood loss was significantly lower in TIVA than IA (−0.853 mL, p = 0.002). There were no significant differences between TIVA and IA in the mean heart rate (−0.225, p = 0.63) and MAP values (−0.126, p = 0.634). The subgroup analyses revealed no significant difference between TIVA and IA when remifentanil was not utilized and whenever desflurane was the IA agent. Conclusion TIVA seemed to have superior intraoperative visibility scores and blood loss during endoscopic sinus surgery when compared to IA. However, the results are not consistent when stratifying the results based on the use of remifentanil and different inhaled anesthetics. Therefore, the conclusion cannot be made that one approach is superior to the other.

OBJECTIVERestoring the proper sagittal alignment in adult spinal deformity (ASD) can improve radiological and clinical outcomes, but pseudarthrosis including rod fracture (RF) is a common problematic complication. The purpose of this study was to analyze the methods for reducing the incidence of RF in deformity correction of ASD.METHODSThe authors retrospectively selected 178 consecutive patients (mean age 70.8 years) with lumbar degenerative kyphosis (LDK) who underwent deformity correction with a minimum 2-year follow-up. Patients were classified into the non-RF group (n = 131) and the RF group (n = 47). For predicting the crucial factors of RF, patient factors, radiographic parameters, and surgical factors were analyzed.RESULTSThe overall incidence of RF was 26% (47/178 cases), occurring in 42% (42/100 cases) of pedicle subtraction osteotomy (PSO), 7% (5/67 cases) of lateral lumbar interbody fusion (LLIF) with posterior column osteotomy, 18% (23/129 cases) of cobalt chrome rods, 49% (24/49 cases) of titanium alloy rods, 6% (2/36 cases) placed with the accessory rod technique, and 32% (45/142 cases) placed with the 2-rod technique. There were no significant differences in the incidence of RF regarding patient factors between two groups. While both groups showed severe sagittal imbalance before operation, lumbar lordosis (LL) was more kyphotic and pelvic incidence (PI) minus LL (PI-LL) mismatch was greater in the RF group (p < 0.05). Postoperatively, while LL and PI-LL did not show significant differences between the two groups, LL and sagittal vertical axis correction were greater in the RF group (p < 0.05). Nonetheless, at the last follow-up, the two groups did not show significant differences in radiographic parameters except thoracolumbar junctional angles. As for surgical factors, use of the cobalt chrome rod and the accessory rod technique was significantly greater in the non-RF group (p < 0.05). As for the correction method, PSO was associated with more RFs than the other correction methods, including LLIF (p < 0.05). By logistic regression analysis, PSO, preoperative PI-LL mismatch, and the accessory rod technique were crucial factors for RF.CONCLUSIONSGreater preoperative sagittal spinopelvic malalignment including preoperative PI-LL mismatch was the crucial risk factor for RF in LDK patients 65 years or older. For restoring and maintaining sagittal alignment, use of the cobalt chrome rod, accessory rod technique, or LLIF was shown to be effective for reducing RF in ASD surgery.
