RESUMO

Objective: To investigate the safety and accuracy of robot-assisted pedicle screw implantation in the adolescent idiopathic scoliosis (AIS) surgery. Methods: The clinical data of 46 patients with AIS who were treated with orthopedics, bone graft fusion, and internal fixation via posterior approach between June 2018 and December 2019 were analyzed retrospectively. Among them, 22 cases were treated with robot-assisted pedicle screw implantation (robot group) and 24 cases with manual pedicle screw implantation without robot assistance (control group). There was no significant difference in gender, age, body mass index, Lenke classification, and preoperative Cobb angle of the main curve, pain visual analogue scale (VAS) score, Japanese Orthopaedic Association (JOA) score between the two groups ( P>0.05). The intraoperative blood loss, pedicle screw implantation time, intraoperative pedicle screw adjustment times, and VAS and JOA scores after operation were recorded. The Cobb angle of the main curve was measured on X-ray film and the spinal correction rate was calculated. The screw position and the accuracy of screw implantation were evaluated on CT images. Results: The operation completed successfully in the two groups. The intraoperative blood loss, pedicle screw implantation time, and pedicle screw adjustment times in the robot group were significantly less than those in the control group ( P<0.05). There was 1 case of poor wound healing in the robot group and 2 cases of mild nerve root injury and 2 cases of poor incision healing in the control group, and there was no significant difference in the incidence of complications between the two groups ( P=0.667). All patients in the two groups were followed up 3-9 months (mean, 6.4 months). The VAS and JOA scores at last follow-up in the two groups were superior to those before operation ( P<0.05), but there was no significant difference in the difference of pre- and post-operative scores between the two groups ( P>0.05). The imaging review showed that 343 screws were implanted in the robot group and 374 screws in the control group. There were significant differences in pedicle screw implantation classification and accuracy between the two groups (89.5% vs 79.1%)( Z=-3.964, P=0.000; χ 2=14.361, P=0.000). At last follow-up, the Cobb angles of the main curve in the two groups were significantly lower than those before operation ( P<0.05), and there was significant difference in the difference of pre- and post-operative Cobb angles between the two groups ( t=0.999, P=0.323). The spinal correction rateswere 79.82%±5.33% in the robot group and 79.62%±5.58% in the control group, showing no significant difference ( t=0.120, P=0.905). Conclusion: Compared with manual pedicle screw implantation, robot-assisted pedicle screw implantation in AIS surgery is safer, less invasive, and more accurate.

RESUMO

OBJECTIVE: Patient feedback surveys provide important insight into patient outcomes, satisfaction, and perioperative needs. Recent critiques have questioned provider-initiated surveys and their capacity to accurately gauge patient perspectives due to intrinsic biases created by question framing. In this study, the authors sought to evaluate provider-independent, patient-controlled social media Instagram posts in order to better understand the patient experience following scoliosis correction surgery. METHODS: Twitter and Instagram were queried for posts with two tagged indicators, #scoliosissurgery or @scoliosissurgery, resulting in no relevant Twitter posts and 25,000 Instagram posts. Of the initial search, 24,500 Instagram posts that did not directly involve the patient's own experience were eliminated. Posts were analyzed and coded for the following criteria: the gender of the patient, preoperative or postoperative timing discussed in the post, and classified themes related to the patient's experiences with scoliosis correction surgery. RESULTS: Females made 87.6% of the Instagram posts about their experience following scoliosis correction surgery. The initial postoperative stage of surgery was mentioned in 7.6% of Instagram posts. The most common theme on Instagram involved offering or seeking online support from other patients, which constituted 85.2% of all posts. Other common themes included concern about the surgical scar (31.8%), discussing the results of treatment (28.8%), and relief regarding results (21.2%). CONCLUSIONS: Social media provided a platform to analyze unprompted feedback from patients. Patients were most concerned with their scoliosis correction surgery in the period of time 2 weeks or more after surgery. Themes that were most commonly found on Instagram posts were offering or seeking online support from other patients and concern about the surgical scar. Patient-controlled social media platforms, like Instagram, may provide a useful mechanism for healthcare providers to understand the patient experience following scoliosis correction surgery. Such platforms may help in evaluating postoperative satisfaction and improving postoperative quality of care.

RESUMO

OBJECTIVE: To explore the characteristics of compensation of unfused lumbar region post thoracic fusion in Lenke 1 and 2 adolescent idiopathic scoliosis. BACKGROUND: Preserving lumbar mobility in the compensation is significant in controlling pain and maintaining its functions. The spontaneous correction of the distal unfused lumbar curve after STF has been widely reported, but previous study has not concentrated on the characteristics of compensation of unfused lumbar region post thoracic fusion. METHOD: A total of 51 Lenke 1 and2 AIS patients were included, whose lowest instrumented vertebrae was L1 from January 2013 to December 2019. For further analysis, demographic data and coronal radiographic films were collected before surgery, at immediate erect postoperatively and final follow-up. The wedge angles of each unfused distal lumbar segments were measured, and the variations in each disc segment were calculated at the immediate postoperative review and final follow-up. Meanwhile, the unfused lumbar curve was divided into upper and lower parts, and we calculated their curve angles and compensations. RESULTS: The current study enrolled 41 females (80.4%) and 10 males (19.6%). Thirty-six patients were Lenke type 1, while 15 patients were Lenke type 2. The average main thoracic Cobb angle and thoracolumbar/lumbar Cobb angle were 44.1 ± 7.7°and 24.1 ± 9.3°, preoperatively. At the final follow-up, the disc wedge angle variation of L1/2, L2/3, L3/4, L4/5 and L5/S1 was 3.84 ± 5.96°, 3.09 ± 4.54°, 2.30 ± 4.53°, - 0.12 ± 3.89° and - 1.36 ± 2.80°, respectively. The compensation of upper and lower coronal lumbar curves at final follow-up were 9.22 ± 10.39° and - 1.49 ± 5.14°, respectively. CONCLUSION: When choosing L1 as the lowest instrumented vertebrae, the distal unfused lumbar segments' compensation showed a decreasing trend from the proximal end to the distal end. The adjacent L1/2 and L2/3 discs significantly contributed to this compensation.

RESUMO

OBJECTIVE: To evaluate the effect of degenerative scoliosis on the difficulty and efficacy of minimally invasive transforaminal lumbar interbody fusion(MIS-TLIF) in the treatment of lumbar spinal stenosis. METHODS: From September 2016 to September 2019, 52 patients with lumbar spinal stenosis treated by MIS-TLIF were retrospectively analyzed, including 16 males and 36 females, aged from 42 to 71(63.44±5.96) years old, the course of disease from 1.5 to 6.5 years, with an average of (3.69±1.10) years. All patients had lower extremity root pain or numbness, 41 patients had intermittent claudication. There were 31 cases of L4, 5 and 21 cases of L5S1. There were 18 cases in scoliosis group, lumbar spinal stenosis combined withdegenerative scoliosis, and 34 cases in stenosis group, lumbar spinal stenosis alone. The perioperative data and postoperative complications were recorded, the postoperative interbody fusion was evaluated by CT, and the clinical outcomes were evaluated by VAS score, Oswestry Disability Index (ODI). RESULTS: All patients were followed up for 12 to 36 months, with an average of (19.58±5.33) months. The operation time and intraoperative bleeding in stenosis group were better than those in scoliosis group (P<0.05). There were no significant differences in postoperative drainage volume, postoperative Hb, CRP, postoperative landing time, discharge time, VAS score at discharge and follow-up, ODI score at 3 months and follow up, postoperative complications and interbody fusion rate between two groups (P>0.05). CONCLUSION: For patients with lumbar spinal stenosis undergoing MIS-TLIF, degenerative scoliosis can lead to prolonged operation time and increased bleeding. However, it has no significant effect on therelief of postoperative symptoms, postoperative complications and the recovery of lumbar function.

RESUMO

OBJECTIVE: To investigate the value of lumbar quantitative CT (QCT) in vertebroplasty for osteoporotic fracture combined with scoliosis. METHODS: The clinical data of 60 patients with osteoporotic fractures combined with different degrees of scoliosis treated by vertebroplasty from December 2017 to December 2019 were retrospectively analyzed. There were 18 males and 42 females, aged from 65 to 81 (72.63±3.34)years old. All patients were received QCT examination before surgery. According to the QCT value, the patients were divided into osteopenia group(QCT>80 g/L, 10 cases, 12 vertebrae), osteoporosis group(QCT 40-80 g/L, 35 cases, 48 vertebrae) and severe osteoporosis group(QCT<40 g/L, 15 cases, 22 vertebrae). The dispersion and leakage of bone cement in the injured vertebrae of patients with different degrees of QCT value were observed, and the QCT value in the selection of puncture point, correction of Cobb angle and recovery of vertebral height were analyzed in the patients. RESULTS: Among 60 cases of 82 vertebrae, 41 cases of 55 vertebrae were punctured by concave unilateral puncture, according for 67.07%. Among them, there were 2 cases with 2 vertebrae in osteopenia group, 26 cases with 35 vertebrae in osteoporosis group, and 13 cases with 18 vertebrae in severe osteoporosis group. There was significant difference in the number of cases with unilateral or bilateral puncture among the three groups (χ2=13.699, P=0.001); there was no significant difference in the number of cases with bone cement leakage among the three groups (χ2=1.403, P=0.496). The Cobb angle of scoliosis was significantly differentbetween preoperative and postoperative follow-up(P<0.05);the height of injured vertebral body was significantly different between preoperative and postoperative follow-up (P<0.05). CONCLUSION: For patients with osteoporotic fracture combined with scoliosis undergoing vertebroplasty, the severity of osteoporosis should be determined according to lumbar QCT detection, and the concave side of scoliosis should be selected for puncture, which is conducive to improving scoliosis, restoring spinal stability and improving surgical safety.

RESUMO

BACKGROUND: Surgical management of cervical kyphosis in patients with NF-1 is a challenging task. Presently, anterior-only (AO), posterior-only (PO) and combined anterior-posterior (AP) spinal fusion are common surgical strategies. However, the choice of surgical strategy and application of Halo traction remain controversial. Few studies have shown and recommended posterior-only approach for cervical kyphosis correction in patients with NF-1. The aim of this study is to evaluate the safety and the effectiveness of halo Traction combined with posterior-only approach correction for treatment of cervical kyphosis with NF-1. METHODS: Twenty-six patients with severe cervical kyphosis due to NF-1 were reviewed retrospectively between January 2010 and April 2018. All the cases underwent halo traction combined with posterior instrumentation and fusion surgery. Correction result, neurologic status and complications were analyzed. RESULTS: In this study, cervical kyphosis Cobb angle decreased from initial 61.3 ± 19.7 degrees to postoperative 10.6 ± 3.7 degrees (P<0.01), with total correction rate of 82.7%, which consist of 45.8% from halo traction and 36.9% from surgical correction. JOA scores were improved from preoperative 13.3 ± 1.6 to postoperative 16.2 ± 0.7 (P<0.01). Neurological status was also improved. There was no correction loss and the neurological status was stable in mean 43 months follow-up. Three patients experienced minor complications and one patient underwent a second surgery. CONCLUSION: Halo traction combined with PO approach surgery is safe and effective method for cervical kyphosis correction in patients with NF-1. A satisfied correction result, and successful bone fusion can be achieved via this procedure, even improvement of neurological deficits can also be obtained. Our study suggested that halo traction combined with PO approach surgery is another consideration for cervical kyphosis correction in patients with NF-1.

RESUMO

A new flat detector and pulsed fluoroscopy technology is available to further reduce radiation exposure in radiological monitoring during scoliosis treatment in children and adolescents. The aim of this study is to compare different settings of the system (opening area(OA) and image quality settings (IQS)) in order to find the optimal parameters with high image quality and the lowest possible radiation exposure. Therefore, we examined four cadaver spines (T1 to sacrum) with the flat detector technique using digital pulsed fluoroscopy and simulated the abdominal soft tissues. The images were merged and evaluated by three different investigators using an established scoring system. For comparison, we used digital radiography images of the cadaver spines. The values for the DAP increased from the small OA (33% ; 0.56 µGy·m²) to the maximum OA (100% ; 0.82 µGy·m²) by 45% (p = .003) and from the low image quality setting (0.57 µGy·m²) to the high setting (0.84 µGy·m²) by 48% (p = .028). Despite the low DAP, the setting 33% OA achieved the best point values for image quality, therefore this setting is clearly preferred. Using a digital fluoroscopy system allows a significant reduction of radiation exposure by a factor of 7.5 (3.88µGy·m² to 0.5µGy·m²) compared to slot- scanning x-ray (EOS). Due to this success, the flat detector and pulsed fluoroscopy technology can be an alternative to established methods such as X-ray and EOS in clinical use.

RESUMO

STUDY DESIGN: Retrospective review. OBJECTIVE: The objective of this study was to report on one institution's use of single bolus micro-dose intrathecal morphine as part of a rapid recovery pathway during posterior spinal fusion (PSF) for adolescent idiopathic scoliosis (AIS) and its comparison to patients whose pain was controlled with patient-controlled analgesia (PCA). SUMMARY OF BACKGROUND DATA: Narcotic substance addiction has risen across all patient populations, including pediatrics. Narcotics have been historically used in complex spine surgeries as a measure of pain control, predominantly provided as PCA and additional take-home medication. METHODS: AIS patients undergoing PSF from 2015 to 2019 were reviewed. In 2018, we instituted a standardized rapid recovery pathway for scoliosis patients undergoing PSF utilizing micro-dose intrathecal morphine (ITM-RRP). Before this, traditional protocol with PCA was used for postoperative management. Perioperative data, morphine consumption and prescription refill requests were compared. RESULTS: There were 373 AIS patients total in this study, of which 250 patients were in the PCA group and 123 in the ITM-RRP Group. Preoperative Cobb angles (P = 0.195), as well as levels fused (P = 0.481) and body mass index (P = 0.075) were similar. 69.4% of ITM-RRP patients had a length of stay ≤3 days, significantly >11.6% of PCA patients (P < 0.001). ITM-RRP patients began ambulating significantly earlier with 84.6% patients out of bed by postoperative day 1 versus 8% PCA patients (P < 0.001). Additionally, ITM-RRP patients had significantly lower VAS pain scores with activity and earlier initial bowel movements (P < 0.001).Postoperative emesis was similar (P = 0.11). No patients had pruritus, respiratory depression, or required supplemental oxygenation. CONCLUSION: This is the first study to show that a rapid recovery protocol utilizing single micro-dose ITM with oral analgesics have adequate recovery, significantly better postoperative pain control and superior perioperative outcomes to traditional protocols using PCA in the AIS population following PSF.Level of Evidence: 3.

RESUMO

STUDY DESIGN: Prospective, multi-centric, cross-sectional study. OBJECTIVE: To analyze the construct validity of the Tampa Scale of Kinesiophobia (TSK) in a cohort of patients with adolescent idiopathic scoliosis (AIS). SUMMARY OF THE BACKGROUND DATA: Back pain is not uncommon in AIS. The fear of movement (kinesiophobia) in response to pain is related to back pain. TSK psychometric properties in AIS patients have not been properly analyzed. METHODS: Patients with AIS and no prior spine surgery were prospectively included. They fulfilled the Spanish version of the TSK-11 questionnaire, a pain intensity numerical rating scale (NRS), refined SRS-22 (SRS-22r), the Hospital Anxiety and Depression Scale (HADS), and item 7 of the Core Outcome Measurement Index (COMI). The sample was split into two groups for the statistical analysis: adolescents and young adults. Cronbach alpha was used to assess internal consistency. Discriminant and concurrent validity were obtained by computing Pearson correlation coefficients between the TSK score and several criterion measures. RESULTS: A total of 275 patients were included-198 adolescents (mean age of 14.6 yrs) and 77 young adults (mean age of 26.9 yrs). The Cobb of largest curve means were 44.9° and 48.9°, respectively. In the adolescent group, the TSK mean (±SD) was 21.5 (±5.93), with a floor effect of 2.5%. In the adult group, the TSK mean was 24.2 (±6.63), with a floor effect of 3.9%. The ceiling effect was 0% in both groups. Cronbach alphas for the adolescent and adult groups were 0.76 and 0.79, respectively. No correlation was found in any group between the TSK score and the curve magnitude or pattern (Lenke classification). The TSK was significantly correlated with HAD depression and SRS-22r in both groups. However, these correlations were weaker in adolescents. In adults, the TSK also significantly correlates with NRS and work/school absenteeism. CONCLUSION: The Spanish version of TSK-11 is a reliable and valid instrument to analyze kinesiophobia in AIS. However, the weak correlation between kinesiophobia and pain intensity, disability, and emotional condition in adolescents requires further study.Level of Evidence: 4.

RESUMO

STUDY DESIGN: Single-center retrospective chart review with minimum 2-year follow up. OBJECTIVE: To determine incidence of pulmonary hypertension in adolescent idiopathic scoliosis patients and to determine the effect of scoliosis surgery on pulmonary hypertension. SUMMARY OF BACKGROUND DATA: Spinal deformity in adolescent idiopathic scoliosis can increase right atrial and ventricular pressures secondary to restrictive lung disease. Pulmonary hypertension leading to cor pulmonale is the most feared outcome, however mild pulmonary hypertension in adolescent idiopathic scoliosis (AIS) patients has been reported. No study has previously examined changes in the improvement of right heart function following scoliosis surgery. METHODS: Cobb angle, 2D-echo signs of structural heart disease, aortic root dimensions, tricuspid regurgitant jet velocity (TRV), pulmonary function tests (PFTs), arterial blood gas (ABG), and patient demographics reviewed. Right ventricular systolic pressure (RVSP) estimated using Bernoulli equation (4[TRV]2) and right atrial pressure. RVSP ≥36 mmHg is a surrogate marker for pulmonary hypertension. All echocardiograms were read by board certified Pediatric Cardiologists. Logistic regression used to assess for differences in TRV between groups. RESULTS: Mean preoperative RVSP was significantly elevated in AIS patients (26.9 ±â€Š0.49; P < 0.001) compared with controls (17.25 + 0.88). Only 47 (21%) Group 1 patients had elevated preoperative TRV (≥2.8 m/s) versus none in Group 2 (P < 0.001). Additionally, logistic regression showed AIS patients have odds ratio of 3.29 for elevated TRV (P = 0.007)-an indirect measure of pulmonary hypertension. In all Group 3 patients, the cardiac function normalized postoperatively (mean TRV = 2.09 + 0.23; P < 0.001). No association found between Cobb angle, aortic root parameters, or pulmonary function tests. CONCLUSION: This study found 13.9% of patients with adolescent idiopathic scoliosis had elevated TRV while controls had no TRV abnormalities. Additionally, RVSP measurements demonstrated mild pulmonary hypertension in AIS patients. These abnormal values normalized postoperatively, indicating the benefits of scoliosis surgery on cardiac function in adolescent idiopathic scoliosis.Level of Evidence: 3.

RESUMO

BACKGROUND: It remains unclear if Pilates is conducive to reducing spinal deformity and improving patients' quality of life (QOL) with scoliosis. The aim of this study was to systematically review the published evidence to determine whether Pilates exercise training is an efficacious therapy for scoliosis. METHODS: Searches was conducted in Medline, Embase, PubMed, Scopus, CINAHL, Physiotherapy Evidence Database (PEDro), Cochrane library, Baidu Scholar, and Green Medical to identify randomized studies that tested the effect of Pilates exercise training on Cobb angle, pain level, trunk range of motion (ROM), angle of trunk rotation, and QOL in idiopathic scoliosis. Separate meta-analyses were performed on the endpoints of these outcome measures. The PEDro scale was used to assess the methodological quality of the included studies. RESULTS: This review included 10 randomized controlled trials (n = 359). PEDro scores ranged from 3 to 10, with the mean score across all articles being 5.3/10 and judged to be of fair quality. The results indicated that Pilates exercises was effective in reducing Cobb angle (standardized mean difference [SMD] = 1.23, 95% confidence interval [CI] = 0.11-2.35), angle of trunk rotation (SMD = 1.37, 95% CI = 1.01-1.73), and pain level (SMD = 2.78, 95% CI = 1.55-4.01), as well as improving trunk ROM (SMD = 1.23, 95% CI = 0.45-2.00), and QOL (SMD = 3.05, 95% CI = 2.59-3.51) in patients with scoliosis. CONCLUSION: Pilates exercise training may reduce the Cobb angle and trunk rotation, relieve pain, increase trunk ROM, and improve QOL for patients with scoliosis. Due to the poor quality of the evidence, however, these results should be interpreted with caution.

RESUMO

BACKGROUND: Early versions of spinal muscular atrophy (SMA) scoliosis correction surgery often involved sublaminar devices. Recently, the utilization of pedicle screws has gained much popularity. Pedicle screws are generally believed to provide additional deformity correction, but pedicle size and rotational deformity limit their application in the thoracic spine, resulting in a hybrid construct involving pedicle screws and sublaminar wire. Studies of the efficacy of hybrid instrumentation in SMA scoliosis are often limited by the scarcity of the disease itself. In this study, we aimed to compare the surgical outcomes between hybrid constructs involving pedicle screws and sublaminar wire and sublaminar wire alone in patients with SMA scoliosis. METHODS: We retrospectively reviewed the clinical records and radiographic assessments of patients with SMA scoliosis who underwent corrective surgery between 1993 and 2017. The radiographic assessments included deformity correction and progressive changes in the major curve angle, pelvic tilt (PT) and coronal balance (CB). The correction of deformities was observed postoperatively and at the patient's 2-year follow-up to test the efficacy of each type of construct. RESULTS: Thirty-three patients were included in this study. There were 14 and 19 patients in the wiring and hybrid construct groups, respectively. The hybrid construct group demonstrated a higher major curve angle correction (50.5° ± 11.2° vs. 36.4° ± 8.4°, p < 0.001), a higher apical vertebral rotation correction (10.6° ± 3.9° vs. 4.8° ± 2.6°, p < 0.001), and a reduced progression of the major curve angle at the 2-year follow-up (5.1° ± 2.9° vs. 8.7° ± 4.8°, p < 0.001). A moderate correlation was observed between the magnitude of correction of the apical vertebral rotation angle and the major curve (r = 0.528, p = 0.002). CONCLUSION: This study demonstrated that hybrid instrumentation can provide a greater magnitude of correction in major curve and apical rotation as well as less major curve progression than sublaminar wire instrumentation alone in patients with SMA scoliosis. Level of evidence III.

RESUMO

BACKGROUND: Although recent studies have investigated the risk factors for PSI, few studies have focused on the impact of scoliotic correction on postoperative shoulder imbalance (PSI), especially in severe and rigid scoliosis (SRS). The purpose of the study was to study the effect of scoliotic correction on PSI in SRS. METHODS: The preoperative, postoperative, and minimum 2-year follow-up radiographs of 48 consecutive patients with SRS who underwent posterior spinal fusion surgery were evaluated. We regarded radiographic shoulder height (RSH) as a shoulder balance parameter and divided the patients into improved and aggravated groups of PSI from pre- to post-operation and from post-operation to last follow-up, respectively. In addition, patients were divided into nine groups based on the observed changes in PSI after surgery and at follow-up, and the correction rate ratios were calculated among the groups. Independent samples T test and Chi-squared test were performed between the improved and aggravated groups of PSI. RESULTS: After surgery, the proximal thoracic curve (PTC) flexibility (P = 0.040), correction rate of the main thoracic curve (MTC) (P = 0.010), and Cobb angle of the lumbar curve (LC) (P = 0.037) were significantly higher, while the ratio of the correction rate of the PTC to the MTC (P = 0.042) was smaller in the aggravated group. At follow-up, the improved group had significantly larger PTC flexibility (P = 0.006), larger ratio of the correction rate of PTC to MTC (P = 0.046), a larger ratio correction rate of PTC to LC (P = 0.027), and a smaller correction rate of LC (P = 0.030). The correction rate ratios of the groups after surgery were as follows: negative to negative (N-N) (1.08) > negative to balance (N-B) (0.96) > negative to positive (N-P) (0.67), B-N (1.26) > B-B (0.94) > B-P (0.89), and P-N (0.34) > P-P (0.83). The order of the correction rate ratio at follow-up was as follows: N-N (0.96) > N-B (0.51), B-B (0.97) > B-P (0.90), and P-B (0.87) > P-P (0.84). CONCLUSION: Harmonizing the correction rate ratio of the PTC, MTC, and LC should be recommended for intraoperative correction and postoperative compensation of PSI. In addition, greater PTC flexibility plays an important role in the spontaneous correction and compensation of PSI in SRS.

RESUMO

Intravenous tranexamic acid (TXA) has been administered to reduce intraoperative blood loss in scoliosis surgery. However, the therapeutic effect of TXA on spinal muscular atrophy (SMA) scoliosis surgery is not well demonstrated. Therefore, this study aimed to assess the efficacy of intravenous TXA in SMA scoliosis surgery. From December 1993 to August 2020, 30 SMA patients who underwent scoliosis surgery (posterior fusion with fusion level of thoracic second or third to pelvis) were retrospectively enrolled and divided into the TXA group and non-TXA (control) group, with 15 patients in each group. Survey parameters were the amount of blood loss, blood transfusion, crystalloid transfusion volume, intubation time, and associated pulmonary complications (including pneumonia, pulmonary edema, and pulmonary atelectasis). The TXA group had significantly lesser blood loss than the control group (p = 0.011). Compared with the control group, the TXA group had significantly lower blood transfusion (p < 0.001), crystalloid volume (p = 0.041), and total transfusion volume (p = 0.005). In addition, the TXA group had fewer postoperative pulmonary complications, and patients with pulmonary complications were associated with a higher relative crystalloid volume and relative total transfusion volume (p = 0.003 and 0.022, respectively). In conclusion, TXA can be effective in reducing intraoperative blood loss and crystalloid fluid transfusions during scoliosis surgery in SMA patients, which may aid in reducing postoperative pulmonary complications.

RESUMO

BACKGROUND: Finding an optimal treatment strategy for adolescent idiopathic scoliosis (AIS) patients remains challenging because of its intrinsic complexity. For mild to moderate scoliosis patients with lower skeletal growth potential (Risser 3-5), most clinicians agree with observation treatment; however, the curve progression that occurs during puberty, the adolescent period, and even in adulthood, remains a challenging issue for clinicians. The aim of the study is to investigate the efficacy of Schroth exercise in AIS patients with lower skeletal growth potential (Risser 3-5) and moderate scoliosis (Cobb angle 20°-40°). METHODS: From 2015 to 2017, data of 64 patients diagnosed with AIS in Peking University Third Hospital were reviewed. Forty-three patients underwent Schroth exercise were classified as Schroth group, and 21 patients underwent observation were classified as observation group. Outcomes were measured by health-related quality of life (HRQOL) and radiographic parameters. HRQOL was assessed using the visual analog scale (VAS) scores for back, Scoliosis Research Society-22 (SRS-22) patient questionnaire. Radiographic spinopelvic parameters were obtained from anteroposterior and lateral X-rays. The pre-treatment and post-treatment HRQOL and radiographic parameters were tested to validate Schroth exercise efficacy. The inter-rater reliability of the radiographic parameters was tested using the interclass correlation coefficient (ICC). The paired t test was used to examine HRQOL and radiographic parameters. Clinical relevance between C2-C7 sagittal vertical axis (SVA) and thoracic kyphosis was analyzed using Spearman correlation. RESULTS: In Schroth group, VAS back score, SRS-22 pain, and SRS-22 self-image domain were significantly improved from pre-treatment 3.0 ±â€Š0.8, 3.6 ±â€Š0.5, and 3.5 ±â€Š0.7 to post-treatment 1.6 ±â€Š0.6 (t = 5.578, P = 0.013), 4.0 ±â€Š0.3 (t = -3.918, P = 0.001), and 3.7 ±â€Š0.4 (t = -6.468, P < 0.001), respectively. No significant improvements of SRS-22 function domain (t = -2.825, P = 0.088) and mental health domain (t = -3.174, P = 0.061) were observed. The mean Cobb angle decreased from 28.9 ±â€Š5.5° to 26.3 ±â€Š5.2° at the final follow-up, despite no statistical significance was observed (t = 1.853, P = 0.102). The mean C2-C7 SVA value decreased from 21.7 ±â€Š8.4 mm to 17.0 ±â€Š8.0 mm (t = -1.224 P = 0.049) and mean T1 tilt decreased from 4.9 ±â€Š4.2 ° to 3.5 ±â€Š3.1° (t = 2.913, P = 0.011). No significant improvement of radiographic parameters and HRQOL were observed in observation group. CONCLUSIONS: For AIS patients with a Risser 3-5 and a Cobb angle 20°-40°, Schroth exercises improved HRQOL and halted curve progression during the follow-up period. Both cervical spine alignment and shoulder balance were also significantly improved after Schroth exercises. We recommend Schroth exercises for patients with AIS.

RESUMO

BACKGROUND: Adolescent idiopathic scoliosis (AIS) patients have lower physical activity levels than normal adolescents, and there is an association with poorer bone and muscle health. This study evaluated the effects of a home-based exercise intervention (E-Fit) on bone mineral density (BMD), muscle function, and quality of life (QoL) in AIS-affected girls. METHODS: A total of 40 AIS females aged 11 to 14 years were randomly assigned to the E-Fit or control group. The E-Fit group performed modified 7-min high-intensity interval training (HIIT) 5 days per week for 6 months. Outcome measures including BMD using dual-energy X-ray absorptiometry (DXA), muscle strength and endurance tests, physical activity levels, and QoL using self-reported questionnaires were assessed at baseline and at 6-month and 12-month follow-up. RESULTS: In total, 14 patients in the E-Fit and 16 in the control group completed the study. The E-Fit group showed a marginally significant interaction effect in the whole body areal BMD at the 6- (p = 0.096) and 12-month follow-ups (p = 0.085). The left arm lean mass in the E-Fit group showed a statistically significant interaction effect between the 6- and 12-month follow-ups (p = 0.046). The E-Fit group showed improvements in physical activity participation, as measured by the Modified Baecke Questionnaire (MBQ), with a significant interaction effect in work index (p = 0.043), sport index (p = 0.050), and total score (p = 0.016) from baseline to the 12-month follow-up. Improvement on self-image were noted in E-Fit group across time. CONCLUSIONS: The present results provided some evidence to support the positive benefits of E-Fit for bone health and muscle function in AIS girls.

RESUMO

BACKGROUND: Degenerative lumbar scoliosis (DLS) combined with spinal stenosis is increasingly being diagnosed in the elderly. However, the appropriate surgical approach remains somewhat controversial. The aim of this study was to compare the results of percutaneous transforaminal endoscopic decompression (PTED) and short-segment fusion for the treatment of mild degenerative lumbar scoliosis combined with spinal stenosis in older adults over 60 years of age. METHODS: Of the 54 consecutive patients included, 30 were treated with PTED and 24 were treated with short-segment open fusion. All patients were followed up for at least 12 months (12-24 months). Patient demographics, and perioperative and clinical outcomes were recorded. Visual analog scale (VAS) scores, Oswestry disability index (ODI) scores, and modified Macnab criteria were used to assess clinical outcomes. At the same time, changes in disc height, segmental lordosis, coronal Cobb angle, and lumbar lordosis were compared. RESULTS: The mean age was 68.7 ± 6.5 years in the PTED group and 66.6 ± 5.1 years in the short-segment fusion group. At 1 year postoperatively, both groups showed significant improvement in VAS and ODI scores compared with preoperative scores (p < 0.05), with no statistically significant difference between groups. However, VAS-Back and ODI were lower in the PTED group at 1 week postoperatively (p < 0.05). According to the modified Macnab criteria, the excellent rates were 90.0 and 91.6% in the PTED and short-segment fusion groups, respectively. However, the PTED group had a significantly shorter operative time, blood loss, postoperative hospital stay, postoperative bed rest, and complication rate. There was no significant difference in radiological parameters between the two groups preoperatively. At the last follow-up, there were significant differences in disc height, segmental lordosis at the L4-5 and L5-S1 levels, and Cobb angle between the two groups. CONCLUSION: Both PTED and short-segment fusion for mild degenerative lumbar scoliosis combined with spinal stenosis have shown good clinical results. PTED under local anesthesia may be an effective supplement to conventional fusion surgery in elderly patients with DLS combined with spinal stenosis.

RESUMO

Purpose: To assess whether the magnitude of lengthening in magnetically controlled growing rod (MCGR) surgeries has an immediate or delayed effect on spinal off-loading. Methods: 9 whole porcine spines were instrumented using two standard MCGRs from T9 to L5. Static compression testing using a mechanical testing system (MTS) was performed at three MCGR lengthening stages (0 mm, 2 mm, and 6 mm) in each spine. At each stage, five cycles of compression at 175N with 25 min of relaxation was carried out. Off-loading was derived by comparing the load sustained by the spine with force applied by the MTS to the spine. Micro-CT imaging was subsequently performed. Results: The mean load sustained by the vertebral body before lengthening was 39.69N, and immediately after lengthening was 25.12N and 19.91N at 2 mm and 6 mm lengthening, respectively; decreasing to 10.07N, 8.31N, and 8.17N after 25 minutes of relaxation, at 0 mm, 2 mm, and 6 mm lengthening stages, respectively. There was no significant difference in off-loading between 2 mm and 6 mm lengthening stages, either instantaneously (p = 0.395) or after viscoelastic relaxation (p = 0.958). CT images showed fractures/separations at the level of pedicle screws in six spines and in the vertebral body's growth zone in five spines after 6 mm MCGR lengthening. Conclusion: This study demonstrated MCGRs cause significant off-loading of the spine leading to stress shielding. 6 mm of lengthening caused tissue damage and microfractures in some spines. There was no significant difference in spine off-loading between 2 mm and 6 mm MCGR lengthening, either immediately after lengthening or after viscoelastic relaxation.

RESUMO

The automatic localization of the lumbar region is essential for the diagnosis of lumbar diseases, the study of lumbar morphology, and the surgical planning. Although the existing researches have made great progress, it still faces several challenges. First, the various lumbar diseases and pathologies cause different abnormalities in the lumbar shape and appearance. Second, the numbers of lumbar vertebrae are irregular (some people have an additional vertebra L6). To tackle these challenges, we propose a novel lumbar region localization method based on bone anatomy feature graphs. Specifically, a feature graph (called LS) considering the anatomy of the sacrum and the lumbar vertebra is proposed to locate the inferior boundary of L5 or L6. A feature graph (called TL) considering the anatomy of the thoracic vertebra and the lumbar vertebra is proposed to locate the superior boundary of L1. Extensive experimental analysis is performed on a public available dataset xVertSeg and a private dataset which contains 197 CT scans. The localization results show that the proposed method is robust and can be applied to normal scans, scoliosis scans, deformity scans, hyperosteogeny scans, 6 lumbar vertebrae scans and lumbar implant scans. The Dice and Jaccard coefficients are 98.09 ± 0.84% and 96.27 ± 1.62% respectively. Graphical Abstract Lumbar Region Localization Framework.

RESUMO

STUDY DESIGN: Retrospective comparative review. OBJECTIVE: The aim of this study was to determine the short-term impact of the COVID-19 pandemic on the demographic and clinical profile of new idiopathic scoliosis (IS) patients, with a particular focus on treatment and late referral. The COVID-19 pandemic has limited health-care services and public access and, as a result, the diagnosis and management of non-COVID-19 health conditions have been compromised. Delayed diagnosis of IS may limit conservative treatment options and subsequently, increase a patient's risk of requiring surgical intervention. METHODS: The volume of spine referrals received and new IS clinic visits were compared between March 15-October 15, 2019 and the same period in 2020. A chart and radiographic review detailed the patient profile at initial presentation. Descriptive statistics and comparative analyses examined the referral source, curve magnitude, skeletal maturity, and prescribed treatment. Late referrals were those with a curve magnitude ≥ 50°, or > 40° and Risser 2 or less. RESULTS: During the 2020 study period, the referral volume decreased 76% and clinic visits 55%. The 2019 cohort was similar in age (13.7 ± 2.1 years vs 13.3 ± 2.3 years, p = 0.08), Risser score distribution (p = 0.32), menarchal status (0.07), and curve magnitude (37.1° ± 3.8° vs 39.0° ± 16.0°, p = 0.22). During the pandemic, there was an increased proportion of referrals made by pediatricians (41 to 54%, p = 0.01). The proportion of brace prescriptions increased from 30 to 42% (p = 0.01). The proportion of surgical bookings and late referrals were increased but did not reach significance. CONCLUSION: Despite no significant increase in the magnitude of the curve at initial presentation or the proportion of late referrals, there was a marked decrease in referral volume, over the first 7 months of the COVID-19 pandemic. This suggests that the majority of expected new IS patients remain undiagnosed. A future increase in late referrals should be anticipated. LEVEL OF EVIDENCE: III.
