Abstract
INTRODUCTION Value in health care is defined as the quotient of outcomes to cost. Both pediatric and adult spinal deformity surgeries are among the most expensive procedures offered today. With high variability in both outcomes and costs in spine surgery today, surgeons will be expected to consider long-term cost effectiveness when comparing treatment options. METHODS We summarize various methods by which value can be increased in complex spine surgery, both through the improvement of outcomes and the reduction of cost. These methods center around standardization, team-based and collaborative approaches, rigorous outcomes tracking through dashboards and registries, and continuous process improvement. RESULTS This manuscript reviews the expert opinion of leading spine specialists on the improvement of safety, quality and improvement of value of pediatric and adult spinal surgery. CONCLUSION Without surgeon leadership in this arena, suboptimal solutions may result from the isolated intervention of regulatory bodies or payer groups. The cooperative development of standardized, team-based approaches in complex spine surgery will lead to the high-quality, high-value care for patients.

Spine Deform 2019; 6:707-711. [PMID: 30348348 DOI: 10.1016/j.jspd.2018.03.010] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/18/2017] [Revised: 01/11/2018] [Accepted: 03/12/2018] [Indexed: 10/28/2022]
Abstract
STUDY DESIGN Multicenter review of prospectively collected data. OBJECTIVE The purpose of this study was to evaluate whether a UIV of T2 reliably results in level shoulders postoperatively. SUMMARY OF BACKGROUND DATA Adolescent idiopathic scoliosis (AIS) patients with a risk of a high left shoulder postoperatively are generally recommended to have instrumentation to T2, those with neutral shoulders a T3 UIV, and those with an elevated right shoulder are recommended a UIV of T4 or below in order to achieve postoperative shoulder balance. METHODS A prospective, multicenter AIS database was queried for subjects with minimum two-year follow-up who underwent posterior spinal fusion to correct their main thoracic deformity. Subjects were grouped based on their proximal fusion level. A high shoulder was defined as >1 cm difference on radiographs. RESULTS A total of 626 subjects met inclusion criteria and were divided by UIVs of T2 189, T3 205, and T4 232. Preoperatively, the groups had similar rates of balanced shoulders (T2 47%, T3 49%, T4 45%) and high left shoulders (T2 8.5%, T3 8.8%, and T4 7.3%). Postoperatively, there was a greater percentage of postoperative shoulder imbalance for T2 (45%) and T3 (48%) UIV groups as compared to T4 (34%, p = .008). As expected, the T2 (46%) and T3 (49%) groups had significantly better upper thoracic curve correction as compared to the T4 group (42%, p < .001). CONCLUSIONS The selection of a T4 UIV results in more shoulder balance postoperatively than T2 or T3, regardless of which shoulder was elevated preoperatively. The selection of a T2 UIV does not guarantee postoperative shoulder balance following posterior treatment of main thoracic curves; however, when compared to the more caudal UIV of T4, an improved upper thoracic curve correction can be anticipated.

Abstract
STUDY DESIGN Prospective database review. OBJECTIVES Determine if use of intraoperative 3D imaging of pedicle screw position provides clinical and cost benefit. SUMMARY OF BACKGROUND Injury or reoperation from malpositioned pedicle screws in adolescent idiopathic scoliosis (AIS) surgery occurs but is increasingly considered to be a never-event. To avoid complications, intraoperative 3D imaging of screw position may be obtained. METHODS A prospective, consecutive AIS database at a high-volume pediatric spine center was examined three years before and after implementation of an intraoperative low-dose computed tomographic (CT) scan protocol. All screws were placed via freehand technique and corrected if found to be outside optimal trajectory on the postplacement CT scan. Demographic and outcome data were compared between cohorts, along with number, location, and reason for screw change. Cost analysis was based on the average cost of revision surgery for screw malposition versus intraoperative CT use. RESULTS There were 153 patients in the pre-CT and 153 in the post-CT cohorts with a minimum 2-year follow-up. Two reoperations were needed for revision of improper screw placement in the pre-CT group and none in the post-CT group. Number of patients needed to harm was 76 (absolute risk increase = 1.31% [-0.49%, 3.11%]). Of those who had intraoperative CT scans, 80 (52.3%) needed on average 1.75 screw trajectories/lengths changed. Forty-three percent were medial breaches; of these, 39% were in the concavity. There were no differences between patients who did and did not need screw repositioning with regard to body mass index (BMI), age, curve size, surgeon/trainee side, screw density, or preoperative and one-year postoperative Scoliosis Research Society-22 patient questionnaire (SRS-22) scores. The average cost of reoperation for malposition was $4,900, whereas the cost of a single intraoperative CT was $232. CONCLUSION Intraoperative CT is an effective tool to prevent reoperation in AIS surgery for incorrect screw placement. Despite high volume, experience, and specialty training, incorrect trajectories occur and systems should be in place for preventable error. LEVEL OF EVIDENCE Level II.

Abstract
STUDY DESIGN Surgeon survey. OBJECTIVES To determine if magnetic resonance imaging (MRI) following implantation of magnetically controlled growing rods (MCGRs) is associated with any adverse events. SUMMARY OF BACKGROUND DATA Magnetically controlled growing rods have been shown to reduce the need for repeated surgical procedures and improve costs when compared to traditional growing rods, but concerns about MRI compatibility exist. MRIs are often clinically indicated in the EOS population. METHODS Pediatric spine surgeons who are members of the Growing Spine Study Group, Children's Spine Study Group, and early international users of this technology were surveyed regarding MRI use after performing MCGR surgery. RESULTS A total of 118 surgeons were surveyed. Four surgeons reported that 10 patients had an MRI with an implanted MCGR. Loss of fixation (0%, 0/10), movement of implants (0%, 0/10), unintended lengthening/shortening (0%, 0/10), or noticeable heating of MCGR (0%, 0/10) were not observed. No problems were observed with function of the MCGR following MRI, and a mean of 2.1 mm was obtained at the next lengthening (range, 0.5-3.0 mm). Two patients had brain MRIs, both of which could be interpreted. All cervical spine MRIs could be interpreted without excessive artifact (100%, 7/7). Six patients had MRIs of the thoracic or lumbar spine, but these were considered uninterpretable as a result of artifact from the MCGR device (0%, 0/6). CONCLUSION These are the first reported cases of MRI use in humans with MCGR. There were no adverse events observed. MCGR rods lengthened as expected following MRI. MRIs of the brain and cervical spine were able to be interpreted, but MRIs of the thoracolumbar spine could not be interpreted because of MCGR artifact. MRIs can be safely performed in patients with MCGRs; however, MRIs of thoracic and thoracolumbar spine may be of limited clinical benefit because of artifact. LEVEL OF EVIDENCE Level IV, case series.

Abstract
PURPOSE Severe, early-onset spinal deformity is common in patients with skeletal dysplasia. These deformities often present at young ages and are associated with significant pulmonary dysfunction. The objective of this study is to verify the effectiveness of growth-friendly spinal instrumentation systems in promoting growth in patients with skeletal dysplasia and early-onset kyphoscoliosis. METHODS A retrospective, multicenter comparative cohort study was performed. Twenty-three patients identified to have a skeletal dysplasia (SKD) were evaluated for diagnosis, age at treatment, gender, and type of growing rod construct (spine vs. rib constructs). Patients were matched by age and construct type with similarly treated patients with early-onset scoliosis (CON) without skeletal dysplasia. Radiographic parameters including maximum coronal and sagittal Cobb angle with levels, T1-S1 height, and T1-T12 height were measured. RESULTS T1-T12 (12.8 vs. 15.2 cm, p = .01) and T1-S1 (21.2 vs. 24.5 cm, p = .05) heights were significantly shorter for the SKD group at implantation, and kyphosis tended to be more severe in children with SKD (p = .80 and .07, respectively). Kyphosis did not improve with treatment. Scoliosis improved (p < .01), and ΔT1-T12 and ΔT1-S1 significantly increased in both groups (p < .01). Complication rates were similar between the two groups; however, patients with SKD had more intraoperative monitoring changes and hardware failures (p < .005). CONCLUSION Although patients with SKD start with shorter spine lengths, gains in spine length appear to be comparable to other forms of EOS. Neuromonitoring changes and implant failures are more common in the SKD group. SIGNIFICANCE The effectiveness of growth-friendly techniques in promoting growth in early-onset spinal deformities in patients with skeletal dysplasia has not been previously studied. We report the first comprehensive review of this topic. Growth-friendly techniques are an appropriate treatment option in this patient population.

Abstract
OBJECTIVE We hypothesized that women undergoing scoliosis surgery who became pregnant would go to full term, have uncomplicated pregnancies, and similar patient-reported outcome measures than non-pregnant patients and healthy controls. METHODS Two hundred five women with adolescent idiopathic scoliosis (AIS) undergoing scoliosis surgery between 1998 and 2015 at several institutions in 1 country and 173 healthy women, without AIS, parous and nulliparous, were selected at random. RESULTS One hundred eight women with scoliosis surgery and no pregnancy (SNP), 97 women with scoliosis surgery and pregnancy (SP), 91 healthy controls and no pregnancy, and 82 healthy controls and pregnancy (HP) were reviewed. Mean follow-up was 5 years in the SNP, 6 years in the SP, 5 years in the healthy controls and no pregnancy, and 5 years in the HP. The average time from surgery to childbirth was 5 years. Back pain (BP) during pregnancy was observed in 48% of the SP and 34% of the HP. BP after childbirth was present in 43% of the SP and 42% of the HP. Patients fused to L3 or L4 experienced more frequent low BP during pregnancy (40%) than those fused above L3 (P < 0.05). Cesarean section (CS) was performed for 64% and 33% in SP and HP, respectively (P < 0.05). As the lowest instrumented vertebra moved caudal to L4, the frequency of CS increased (P < 0.05; R = 0.8). The majority of CS in SP were performed in patients fused to L4 (55%) versus patients fused above and to L3 (45%) (P < 0.05). The most common analgesia for CS was spinal block (75% in SP and 86% in HP). Patients fused to L4 required general anesthesia significantly more often (7%) versus those fused above L4 (4%, P < 0.05). The health-related quality of life after spinal fusion showed general satisfaction and were similar for SNP and SP (mean 3.84 and 3.91, respectively). No sexual dysfunction was reported. CONCLUSIONS Women with a history of spinal fusion for AIS fused to L3 or L4 reported a higher incidence of low BP, and CSs are more frequently required. This risk increased to 55% when spinal fusion to L4 was performed. The quality of life and sexual function were at the same level in women after scoliosis surgery than in healthy controls.

Abstract
STUDY DESIGN Retrospective cross-sectional, longitudinal radiographic analysis. OBJECTIVE To report the natural history of spinopelvic parameters in achondroplasia. SUMMARY OF BACKGROUND DATA Sagittal spinal deformity is common in children with achondroplasia. However, few data exist on their normative spinal parameters. METHODS Lateral standing spine radiographs of children with achondroplasia were reviewed. Measurements included thoracic kyphosis, lumbar lordosis (LL), thoracolumbar kyphosis (TLK), pelvic incidence (PI), T1 pelvic angle (TPA), and sagittal balance (SVA). Comparison between age groups and longitudinal analysis of children with minimum five-year radiographic evaluation was performed; evolution of radiographic measurements was assessed. Children who underwent surgical correction of TLK were studied separately to describe changes of sagittal spinal parameters associated with TLK surgical correction. RESULTS In cross-sectional analysis, 745 radiographs (282 children) were measured. During the first three years, TLK decreased and LL and sacral slope increased significantly. After age 3 years, TLK decreased gradually until age 10. Afterwards, TLK decrease became non-significant. PI increased gradually after age 10. In the longitudinal group, 81 children were followed an average of 8.7 (5-19) years between age 4.4 and 13.1 years. TLK decreased; LL and PI increased significantly. TPA and SVA remained within the normal range although changes with growth were statistically significant. In the surgical group, 19 children underwent surgical TLK correction. Apart from TLK correction, no sagittal parameters changed significantly after surgery. These 19 children had higher TLK and lower LL compared with a nonsurgical group at similar average age. CONCLUSION In children with achondroplasia, TLK improvement occurs primarily before age 3 years; hyperlordosis at the lumbosacral level is the compensatory mechanism. Significant changes in the sagittal spinal parameters occur early in life, suggesting the importance of attention to sagittal malalignment to prevent any possible clinical sequelae of severe hyperlordosis.

Abstract
STUDY DESIGN Retrospective review of a prospective cohort. OBJECTIVE To identify patient and surgical factors that alter the length of postoperative intensive care unit (ICU) stays after spinal fusion/instrumentation in patients with neuromuscular scoliosis secondary to cerebral palsy (CP). SUMMARY OF BACKGROUND DATA High perioperative complication rates in patients with CP contribute to the practice of utilizing the ICU postoperatively for monitoring. However, this is costly and little is known regarding which patients truly need this increased acuity of care. METHODS A prospective, multicenter database was queried for patients with CP who underwent spinal fusion and instrumentation. Patients with an ICU length of stay (LOS) ≤1 day were assumed to not have required postoperative ICU admission. Demographic and surgical characteristics were compared between those with ICU LOS of ≤1 day versus >1 day. A classification and regression tree (CART) analysis was utilized to create a decision algorithm for postoperative ICU admission. RESULTS Three hundred twenty-four patients were identified with a mean ICU LOS of 4.7 days (range 0-47). Sixty-eight patients (21%) had an ICU LOS ≤1 day and 256 patients (79%) had an ICU LOS >1 day. CART analysis demonstrated that the institution where the surgery was performed was the primary predictor with two groups: sites that almost routinely had ICU stay >1 day (92%) and those that were split (50.5% >1 day). In the latter group, an operative time greater than 4 hours was a risk factor for a longer ICU stay. CONCLUSION Because of their heterogeneous makeup, CP patients should be evaluated individually and their postoperative disposition should not be based on institutional tradition but instead on objective surgical factors. For those patients with surgical times less than 4 hours, discussions should be held regarding the safety of a postoperative disposition to a regular floor. LEVEL OF EVIDENCE Level III.

Abstract
The evaluation and management of spinal disorders is complex and constantly evolving. Back pain and spinal deformity are substantial contributors to hospital and outpatient physician visits even for young patients. With new insights into the etiology, clinical presentation, and evaluation, children can be more accurately diagnosed and treated. Patients with adolescent idiopathic scoliosis may undergo selective fusion to preserve motion segments, and in some cases, vertebral body tethering or other growth-modification techniques may provide correction with motion preservation in this rapidly changing specialty. The understanding of spinopelvic parameters (pelvic incidence, pelvic tilt, sacral slope) and sagittal balance as they relate to clinical health status has provided surgeons with valuable guidance when managing pediatric and adult spinal deformity. An evidence-based approach to the management of spinal disorders across the continuum of ages has the goal of improving the value of care through optimization of outcomes and limitation of costs and complications. There are new paradigms in the management of spinal disorders and evidence-based approaches to the evaluation and management of patients across the ages.

Abstract
STUDY DESIGN Biomechanical numerical simulation analysis of implant design and density in adolescent idiopathic scoliosis posterior instrumentation. OBJECTIVES To evaluate the combined effect of pedicle screw design and density on deformity correction and construct load-sharing capacity. SUMMARY OF BACKGROUND DATA Screw density is an area of popular study because of the impact of cost and potential patient morbidity of higher-density constructs. Using fewer screws raises concern about reduced correction and greater forces on each screw. METHODS Personalized spinal numerical models were created for five patients. The correction techniques from five spine surgeons using both a high- and a low-density implant pattern (2 vs. 1.4 ± 0.22 screws/level) with uniaxial, multiaxial, and favored angle screws were simulated. The predicted correction and forces sustained by the implants were compared. The postoperative load-sharing capacity of a high- and a low-density construct, with or without crosslinks, was compared by simulating daily activities motions. RESULTS The major coronal curve correction was similar with high- and low-density constructs (73% ± 10% vs. 72% ± 10%; p > .05) but was higher when using uniaxial (77% ± 8%) compared to multiaxial (69% ± 11%) and favored angle screws (71% ± 10%; p = .009). High- and low-density constructs sustained similar intraoperative peak forces (305 ± 61 N vs. 301 ± 73 N; p = .23) regardless of screw design (all p > .05). Multiaxial and favored angle screws reduced the peak axial force by 23% and 38% compared to uniaxial screws (p = .007). The high-density construct reduced the postoperative loads sustained by each implant by 31% (p = .006). Crosslinks had no effect on load sharing (p = .23). CONCLUSION High- and low-density implant patterns achieved similar coronal correction with equivalent capacity to share corrective forces regardless of the screw design. Increased degrees of freedom of the screw head reduces the capacity to correct coronal deformity but generates lower bone-screw forces. The reduced number of screws increased the postoperative forces sustained by each screw, but its effect on potential complications requires further investigations. LEVEL OF EVIDENCE Level 4.

Abstract
STUDY DESIGN Retrospective review of prospectively collected data. OBJECTIVE To determine whether adolescent idiopathic scoliosis (AIS) patients with active complications at two-year follow-up demonstrate lower Scoliosis Research Society (SRS-22) questionnaire scores. SUMMARY OF BACKGROUND DATA There is limited evidence as to whether the SRS-22 is sensitive to complications in postoperative AIS patients. METHODS Surgical patients with SRS-22 scores completed at two-year follow-up were included. Five groups were created: no complication, minor complication resolved by 2 years, major complication resolved by 2 years, minor complication active, and major complication active at 2 years. Likelihood of reaching a minimal clinically important difference (MCID) for pain (0.20) and self-image (0.98) was evaluated. RESULTS 1,481 patients were identified. Major complications active at two years existed in 2.2% of patients. These patients had the lowest score in all domains and total scores (p < .05). If a minor complication was active, scores were impacted for pain, self-image, satisfaction, and total (p < .05). No differences were found between no complication and resolved complications. Patients with active major complications were more likely to have a pain score that worsened from pre- to two years reaching MCID (52%) compared to the other four groups (range 18%-29%, odds ratio [OR] 3.6, p < .001). They also had a nonsignificant decreased rate of improvement of self-image score at an MCID level (42% vs. range 51%-66%, OR 0.56, p = .10). CONCLUSIONS When timing is considered, the SRS-22 demonstrates the ability to discriminate between patients with and without a complication. Active experience of a major complication impacted SRS-22 scores, in particular, the rate of worsening scores for pain, self-image, function, and total score. LEVEL OF EVIDENCE Level III.

Abstract
INTRODUCTION Sagittal alignment abnormalities in Scheuermann kyphosis (SK) strongly correlate with quality of life measures. The changes in spinopelvic parameters after posterior spinal fusion have not been adequately studied. This study is to evaluate the reciprocal changes in spinopelvic parameters following surgical correction for SK. METHODS Ninety-six operative SK patients (65% male; age 16 years) with minimum 2-year follow-up were identified in the prospective multicenter study. Changes in spinopelvic parameters and the incidence of proximal (PJK) and distal (DJK) junctional kyphosis were assessed as were changes in Scoliosis Research Society-22 (SRS-22) questionnaire scores. RESULTS Maximum kyphosis improved from 74.4° to 46.1° (p < .0001), and lumbar lordosis was reduced by 10° (-63.3° to -53.3°; p < .0001) at 2-year postoperation. Pelvic tilt, sacral slope, and sagittal vertical axis remained unchanged. PJK and DJK incidence were 24.2% and 0%, respectively. In patients with PI <45°, patients who developed PJK had greater postoperative T2-T12 (54.8° vs. 44.2°, p = .0019), and postoperative maximum kyphosis (56.4° vs. 44.6°, p = .0005) than those without PJK. In patients with PI ≥45°, patients with PJK had less postoperative T5-T12 than those without (23.6° vs. 32.9°, p = .019). Thoracic and lumbar apices migrated closer to the gravity line after surgery (-10.06 to -4.87 mm, p < .0001, and 2.28 to 2.10 mm, p = .001, respectively). Apex location was normalized to between T5-T8 in 68.5% of patients with a preoperative apex caudal to T8, whereas 90% of patients with a preoperative apex between T5 and T8 remained unchanged. Changes in thoracic apex location and lumbar apex translation were associated with improvements in the SRS function domain. CONCLUSION PJK occurred in 1 in 4 patients, a lower incidence than previously reported perhaps because of improved techniques and planning. Both thoracic and lumbar apices migrated closer to the gravity line, and preoperative apices caudal to T8 normalized in more than two-thirds of patients, resulting in improved postoperative function. Individualizing kyphosis correction to prevent kyphosis and PI mismatch may be protective against PJK.

Abstract
Basilar impression is a cranial base abnormality associated with osteogenesis imperfecta (OI) with serious neurologic implications but controversial treatment options. Combined anterior and posterior decompression with long-segment posterior fusion is often recommended. We report a patient with OI (Sillence type III) with basilar impression treated with halo traction followed by posterior surgery. The patient was a 12-year-old female with a presentation of hiccups and change in upper extremity function. Diagnostic imaging revealed syringomyelia, compensated hydrocephalus, basilar impression, and Chiari type I malformation. The patient was treated with halo traction followed by posterior decompression fusion from the occipital bone to C2. Bone fusion and improved syrinx were evident on images during the 5 years of follow-up. Five years after surgery, syrinx recurred and the fourth ventricular catheter was revised. The treatment with halo traction followed by posterior-only surgery of basilar impression associated with OI resulted in a good postoperative outcome.

Abstract
BACKGROUND Proper contribution of the scapulothoracic joint is necessary for adequate shoulder complex function. Associations between trunk shape and abnormal scapular kinematics and subsequent shoulder dysfunction have been established; however, the extent of shoulder dysfunction in adolescent idiopathic scoliosis (AIS) is still poorly understood. The purpose of this study was to perform a comprehensive analysis of scapular kinematics during multiplanar arm motion in patients with AIS and compare kinematics and patient-reported function with that of a typically developing cohort. METHODS Typically developing adolescents (n=33) and patients with AIS (n=26) with no history of spine or shoulder surgery were recruited for this study. A 3-dimensional optoelectronic motion capture system was used to analyze scapular kinematics in 4 positions: rest, full abduction, forward reach, and hand to spine. Subjects in each group also completed the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire as a measure of patient-reported function. RESULTS The convex shoulders of the patients with AIS exhibited deficits in scapular upward rotation and posterior tilt in all positions and reduced protraction range of motion during reaching. The AIS group also reported worse patient-perceived shoulder function than the typically developing group; however, this dysfunction was not related to specific scapular kinematic patterns. CONCLUSIONS Patients with AIS show alterations in scapular kinematics that are associated with shoulder pathology. Despite displaying an unaffected ability to place the hand in space, the underlying joint mechanics place these adolescents at risk for future pathology. Accordingly, consideration of scapulothoracic and glenohumeral joint function is warranted in the treatment of AIS. LEVEL OF EVIDENCE Level III-cross-sectional comparison.

Abstract
INTRODUCTION Previous randomized controlled trials have demonstrated the efficacy of antifibrinolytic agents in the reduction of intraoperative blood loss in adolescent idiopathic scoliosis (AIS) surgery. Tranexamic acid (TXA) was found to be more effective at reducing total blood loss compared with epsilon-aminocaproic acid (AM) than placebo. We set out to study whether or not the level 1 evidence can be corroborated in a large multicenter, multisurgeon cohort. METHODS Estimated blood loss (EBL), cell saver transfused, and percent of total blood volume (%EBL) was retrospectively assessed from a prospective-collected multicenter AIS registry. Volume of allogeneic blood transfusion data was not uniformly available. The cohort was divided into: 1. TXA (N = 525; 2006-2014), 2. Amicar (N = 117; 2005- 2014), and 3. no antifibrinolytic (N = 1127; 2005-2013) groups. Comparisons between the three groups and between antifibrinolytic (Amicar or TXA) versus no antifibrinolytic (NA) groups were performed using ANOVA with Bonferroni correction and the t-test, respectively. Multivariate analysis was used to control for surgical and surgeon factors. RESULTS EBL, %EBL, and cell saver transfused was significantly lower in TXA (742.3 mL, 21.3% and 191.8 mL, respectively) than NA (1,010.6 mL, 29.8% and 276.6 mL, respectively) and AM (1,420.6 mL, 38.9% and 456.0 mL, respectively), (p < 0.0001), with AM having the greatest values among the three groups. These parameters were normalized by number of levels fused and Cobb magnitude. A similar pattern was observed, with AM having the highest normalized values and TXA group the lowest among all three groups. After further controlling for surgeon, total operative time, and osteotomy performed, multivariable analysis revealed that EBL/level, %EBL/level, and cell saver/level transfused were significantly lower in the TXA group compared to the NA group (p = 0.0014, p = 0.0058, and p = 0.0031, respectively), whereas, no difference was observed between the AM and NA groups (p = 0.1028, p = 0.2523, and p = 0.5274, respectively). The differences between TXA and AM were diminished (p = 0.5512, p = 0.6751, and p = 0.0978, respectively). CONCLUSION Intraoperative administration of TXA significantly reduces EBL, %EBL, and cell saver transfused during AIS surgery. After taking operative and surgeon factors into consideration, %EBL was not significantly different between TXA and Amicar groups in the practice setting.

Abstract
BACKGROUND Neuromuscular scoliosis is often treated with posterior spinal fusion, with or without anterior release, and either a same-day or staged, 2-day procedure. METHODS We retrospectively reviewed 222 patients from a prospectively collected, multi-center database of patients with cerebral palsy scoliosis with 2-year follow-up. Baseline characteristics, perioperative, radiographic, and HRQoL measures were compared in six sub-analyses: (1) staged versus same-day surgeries, (2) posterior-only fusion (PSF) versus anterior-posterior spinal fusion (APSF), (3) same-day versus staged PSF, (4) staged versus same-day APSF, (5) same-day PSF versus same-day APSF, (6) staged PSF versus staged APSF. RESULTS Staged patients had larger curves and more pelvic obliquity, longer anesthesia and surgical times, longer hospital and ICU stays (p < 0.001), and more days intubated (p = 0.021). The staged PSF group had larger curves (p = 0.006), longer anesthesia (p = 0.020) and surgeries (p = 0.007), hospital (p = 0.009) and ICU stays (p = 0.028) compared to same-day PSF. The staged APSF group had longer hospital (p < 0.001) and ICU stays (p = 0.004) and anesthesia and surgeries (p < 0.001). Same-day APSF was associated with larger curves (p < 0.002), longer anesthesia (p = 0.012) and surgeries (p = 0.042), greater residual curves (p = 0.035), and greater absolute correction (p = 0.007) compared to same-day PSF. The staged APSF group had longer anesthesia times (p < 0.001) compared to the staged PSF group. No sub-analysis revealed significant differences in baseline characteristics, complications, or HRQoL. CONCLUSION Staged and circumferential approaches tend to be used for greater deformity, but were not associated with superior deformity correction, and were associated with longer operative time, hospital stays, ICU stays, and days intubated. However, for the most severe deformity, other patient factors may play more important roles in treatment decisions given that patients treated with a staged PSF or an APSF, whether staged or not, were similar at baseline.

Abstract
CASE In a patient who underwent a thoracoscopic anterior release combined with a posterior spinal fusion for juvenile idiopathic scoliosis, unilateral loss of neuromonitoring signals was noted during the posterior instrumentation, and epidural pneumorrhachis was identified by intraoperative O-arm imaging. An immediate laminectomy and decompression of epidural fat and air were performed, resulting in return of the neuromonitoring signals. The patient had no clinical motor or neurological deficits postoperatively, and the posterior spinal fusion was completed successfully 3 days later. CONCLUSION Epidural pneumorrhachis is a possible complication of scoliosis surgery with pedicle screw fixation, which can result in the intraoperative loss of neuromonitoring signals; however, rapid identification and intervention can result in an excellent outcome.

Abstract
Aims The aim of this study was to compare the outcomes of surgery using growing rods in patients with severe versus moderate early-onset scoliosis (EOS). Patients and Methods A review of a multicentre EOS database identified 107 children with severe EOS (major curve ≥ 90°) treated with growing rods before the age of ten years with a minimum follow-up of two years and three or more lengthening procedures. From the same database, 107 matched controls with moderate EOS were identified. Results The mean preoperative major curve was 101° (90 to 139) in the severe group and 67° (33° to 88°) in the moderate group (p < 0.001), which was corrected at final follow-up to 57° (10° to 96°) in the severe group and 40° (3° to 85°) in the moderate group (p < 0.001). T1-S1 height increased by a mean of 54 mm (-8 to 131) in the severe group and 27 mm (-4 to 131) in the moderate group at the initial surgery (p < 0.001), and by 50 mm (-17 to 200) and 54 mm (-11 to 212), respectively, during distraction (p = 0.84). The mean number of complications per patient was 2.6 (0 to 14) in the severe group and 1.9 (0 to 10) in the moderate group (p = 0.040). Five patients (4.7%) in the severe group and three (2.8%) in the moderate group developed a neurological deficit postoperatively (p = 0.47). Conclusion Severe EOS can be treated effectively using growing rods, but the risk of complications is high. Cite this article: Bone Joint J 2018;100-B:772-9.

Abstract
UNLABELLED Bone disease is prevalent among patients with inflammatory bowel disease (IBD), though bone density screening remains underutilized. We used CT scans performed for other indications in IBD patients to identify and monitor osteopenia using CT attenuation values at the lumbar spine. Significant rates of bone disease were detected which would have otherwise gone undiagnosed. INTRODUCTION Osteoporosis affects about 14-42% of patients with IBD. Though screening is recommended in IBD patients with risk factors, it remains underutilized. In patients with newly diagnosed IBD, we used CT scans performed for other indications to identify and monitor progression of osteopenia. METHODS Using the Ocean State Crohn's and Colitis Area Registry, we identified adult patients with one or more abdominal CT scans. Each patient had two age- and gender-matched controls. Radiologists measured attenuation through trabecular bone in the L1 vertebral body recorded in Hounsfield units (HU). Generalized estimating equations were used to measure how HU varied as a function of gender, type of IBD, and age. RESULTS One hundred five IBD patients were included, and 72.4% were classified as "normal" bone mineral density (BMD) and 27.6% as potentially osteopenic: 8.6% with ulcerative colitis and 19.0% with Crohn's disease. We found a decrease in bone density over time (p < 0.001) and that BMD decreases more in Crohn's disease than in ulcerative colitis (p < 0.004). Sixty patients had two CT scans, and mean loss of 9.3 HU was noted. There was a non-significant decrease in BMD over time in patients exposed to > 31 days of steroids and BMD was stable with < 30 days of steroid exposure (p < 0.09). CONCLUSION Using CT scans obtained for other indications, we found low rates of osteopenia and osteoporosis that may otherwise have gone undiagnosed. Refinement of opportunistic screening may have advantages in terms of cost-savings and earlier detection of bone loss.

Abstract
BACKGROUND The true benefits of scoliosis surgery in cerebral palsy (CP) remain uncertain. Our aims were to determine the benefits of spinal fusion according to health-related quality of life (HRQoL) improvement at long-term follow-up and to explore the effect of surgery-related complications on clinical outcomes. METHODS The cases of consecutive patients who had Gross Motor Function Classification System (GMFCS) level-IV or V cerebral palsy with 5-year follow-up from a prospective, longitudinal, multicenter database were analyzed. Caregivers completed the Caregiver Priorities and Child Health Index of Life with Disabilities (CPCHILD) questionnaire and 4 Likert-type anchor questions preoperatively and at 1, 2, and 5 years of follow-up. Data on complications were collected prospectively. Preoperative CPCHILD scores were compared with postoperative scores at the 1, 2, and 5-year follow-up evaluations. Preoperative CPCHILD scores were compared with postoperative scores at the 1, 2, and 5-year follow-up evaluations using repeated-measures analysis of variance (ANOVA). Spearman correlation coefficient was used to explore the association between changes in the CPCHILD at 1, 2, and 5-year follow-up and the reported complications within the follow-up period. Similarly, a comparative analysis between the percentage distribution of the answers to the 4 anchor questions and the reported complications was also performed. RESULTS Sixty-nine patients with a mean age (and standard deviation) of 13.4 ± 2.6 years at enrollment were analyzed. The major Cobb angle was a mean of 81.9° ± 26.7° preoperatively and improved to a mean of 28.7° ± 14.4° at 2 years and 30.7° ± 15.3° at 5 years postoperatively. Significant improvements in CPCHILD personal care, positioning, and comfort domains were noted at all time points. The mean increase in the total score was 7.19 (p < 0.001) at 1 year, and the score gain was maintained at 2 and 5 years postoperatively. The overall complication rate was 46.4% at 1 year, 1.4% between 1 and 2 years, and 4.3% at 2 to 5 years postoperatively, with surgical intervention required in 6 patients within 1 year and in 2 additional patients within 5 years following scoliosis surgery. There was no correlation between complications and CPCHILD scores postoperatively at all time points, with the only exception of a weak correlation (ρ = -0.450, p = 0.002) with CPCHILD comfort score at 1 year after surgery. CONCLUSIONS Scoliosis surgery in patients with CP leads to a significant improvement in HRQoL, which is maintained 5 years following surgery. The substantial complication rate does not correlate with HRQoL changes postoperatively, suggesting that the benefits of surgery outweigh the risks in this fragile population.

Abstract
An adolescent male with late-onset Pompe disease (glycogen storage disease type II) presented with a history of restrictive airway disease and a near-cardiorespiratory arrest during anesthesia for a liver biopsy initially thought to be due to bronchospasm. During a subsequent posterior spinal fusion procedure, he suffered cardiorespiratory arrest resulting in the procedure being aborted. Bronchoscopy performed shortly after resuscitation revealed an undiagnosed narrowing of the distal trachea and bronchi. This is the first description of a patient with late-onset Pompe disease with undiagnosed critical tracheal stenosis due to the progression of thoracic lordosis, which was ultimately relieved by posterior spinal fusion.

Abstract
Despite recent research and improvements in spinal implants, complications remain frequent in patients who undergo pediatric spinal deformity surgery. Although the rate of neurologic injury after pediatric spinal deformity surgery is low, the rate of surgical site infection after pediatric spinal deformity surgery is high, particularly in patients who have neuromuscular scoliosis. Although symptomatic implant complications that require revision surgery are rare with the use of modern spinal fusion constructs, they are common in patients who have early-onset scoliosis. Patients who have perioperative respiratory or gastrointestinal complications benefit from early recognition and supportive treatment. The cause of perioperative complications in patients who undergo pediatric spinal deformity surgery often is multifactorial; therefore, surgeons should understand the numerous risk factors for and strategies for the prevention of pediatric spinal deformity surgery complications.

Abstract
ObjectivesTelemedicine is the use of telecommunication to provide healthcare remotely. We sought to quantify time/cost savings and satisfaction between a cohort of telemedicine and inperson visits in a tertiary paediatric orthopaedic clinic.MethodsTime for clinical visits and wait times were compared between telemedicine and inperson visits. Costs to patients and department were also calculated for both visit types. Parents completed a five-item satisfaction survey regarding their telemedicine experience.ResultsVisit times (15 vs 68 min, P<0.001) and wait times (2 vs 33 min, P<0.001) were shorter for telemedicine visits. Families saved 85 miles of driving and $50 in costs per telemedicine visit. Labour cost saved for a telemedicine visit was $24/patient. More than 90% of patients were satisfied with the telemedicine service.ConclusionTelemedicine can be used in a sports medicine setting to provide care that reduces costs while maintaining high levels of patient satisfaction.Level of evidenceLevel III.

Abstract
Morbid obesity is a barrier to kidney transplantation due to inferior outcomes, including higher rates of new-onset diabetes after transplantation (NODAT), delayed graft function (DGF), and graft failure. Laparoscopic sleeve gastrectomy (LSG) increases transplant eligibility by reducing BMI in kidney transplant candidates, but the effect of surgical weight loss on posttransplantation outcomes is unknown. Reviewing single-center medical records, we identified all patients who underwent LSG before kidney transplantation from 2011-2016 (n = 20). Post-LSG kidney recipients were compared with similar-BMI recipients who did not undergo LSG, using 2:1 direct matching for patient factors. McNemar's test and signed-rank test were used to compare groups. Among post-LSG patients, mean BMI ± standard deviation (SD) was 41.5 ± 4.4 kg/m2 at initial encounter, which decreased to 32.3 ± 2.9 kg/m2 prior to transplantation (P < .01). No complications, readmissions, or mortality occurred following LSG. After transplantation, one patient (5%) experienced DGF, and no patients experienced NODAT. Allograft and patient survival at 1-year posttransplantation was 100%. Compared with non-LSG patients, post-LSG recipients had lower rates of DGF (5% vs 20%) and renal dysfunction-related readmissions (10% vs 27.5%) (P < .05 each). Perioperative complications, allograft survival, and patient survival were similar between groups. These data suggest that morbidly obese patients with end-stage renal disease who undergo LSG to improve transplant candidacy, achieve excellent posttransplantation outcomes.

Abstract
BACKGROUND Small bowel necrosis after enteral feeding through a jejunostomy tube (tube feed necrosis, TFN) is a rare, serious complication of major abdominal surgery. However, strategies to reduce the incidence and morbidity of TFN are not well established. Here, in the largest series of TFN presented to date, we report our institutional experience and a comprehensive review of the literature. METHODS Eight patients who experienced TFN from 2000 to 2014 after major abdominal surgery for oncologic indications at the University of Cincinnati were reviewed. Characteristics of post-operative courses and outcomes were reviewed prior to and after a change in tube-feeding protocol. The existing literature addressing TFN over the last three decades was also reviewed. RESULTS Patients with TFN ranged from 50 to 74 years old and presented with upper gastrointestinal tract malignancies amenable to surgical resection. Six and two cases of TFN occurred following pancreatectomy and esophagectomy, respectively. Prior to TF protocol changes, which included initiation at a low rate, titrating up more slowly and starting at one-half strength TF, three of six cases of TFN (50%) resulted in mortality. With the new TF protocol, there were no deaths, goal TF rate was achieved 3 days later, symptoms of TFN were recognized 3 days earlier, and re-operation was conducted 1 day earlier. CONCLUSION This case series describes a change in clinical practice that is associated with decreased morbidity and mortality of TFN. Wider implementation and further refinement of this tube-feeding protocol may reduce TFN incidence at other institutions and in patients with other conditions requiring enteral nutrition.
