RESUMO

Early-onset scoliosis (EOS) encompasses a wide variety of challenging to treat spinal deformities occurring in children before 10 years of age. The Classification of Early-Onset Scoliosis (C-EOS) has emerged as a useful classification for both clinical and research purposes, as have similar classifications of surgery and complications in the EOS population. Approaches to both nonsurgical and surgical management of EOS have changed dramatically in recent years. There has been a resurgence of interest in nonsurgical management of EOS following several reports of success with serial Mehta cast treatment. Distraction-based surgical approaches, whether rib- or spine-based, remain the mainstay of surgical treatment. The introduction and widespread adoption of magnetically controlled growing rods (MCGR) has altered the need for repeat surgeries for lengthening in distraction based surgery. However, it remains unclear whether overall complication and unplanned revision surgery rates will be improved over historical traditional growing rods or rib-based distraction. Conversion of growth-friendly instrumentation to a final fusion remains a challenging procedure, with high rates of complications and revision surgeries.

RESUMO

Objectives: To evaluate the effect of minimally invasive lateral lumbar interbody fusion (LLIF/OLIF) on the sagittal balance of adult degenerative scoliosis. Methods: From January 2014 to June 2017, a total of 23 patients with degenerative scoliosis underwent staged minimally invasive surgery in Shanghai Ruijin Hospital. All patients were implanted with LLIF or OLIF cage from the lateral approach first, and was followed by the posterior percutaneous pedicle screw fixation or pedicle screw fixation via Wiltse approach. If the sagittal deformity correction was not satisfactory after the first surgery, a posterior osteotomy can be performed during the second stage operation. A biplanar X-ray of the whole spine was taken with the EOS imaging system before and after surgery. The EOS software was used to measure and evaluate the patient's sagittal balance parameters including pelvic incidence (PI), pelvic tilt (PT), lumbar lordosis (LL), the sagittal vertical axis (SVA) and the coronal Cobb angle. The visual analogue scale (VAS) score for low back pain, the Oswestry Disability Index (ODI) score were evaluated before and after surgery. Paired t test or repeated measures ANOVA was used to compare the data before and after surgery. Results: There were 6 males and 17 females with a mean age of (72±4) years (62-79 years). Nine patients were treated with LLIF and 14 patients with OLIF. Sixteen cases were implanted with three cages, five with two cages and two with four cages. The mean follow-up period was 24.2 months (15-42 months). After the first operation, the Cobb angle of the patient was significantly improved (18°±7° vs 33°±8°, t=13.2, P<0.01). All the parameters for sagittal balance, including PI-LL (20°±8° vs 31°±8(o)), SVA ((5.3±2.0) cm vs (8.2±3.5) cm), PT (16°±6° vs 23°±4°) were all significantly improved as well (t=6.8, 4.5, 9.0, ALL P<0.01). At the last follow-up, the VAS score of low back pain (3.4±1.1 vs 6.3±1.0) and ODI scores (27.3%±3.0% vs 47.1%±5.9%) were also significantly improved (t=11.3, 17.8, both P<0.01). No major complications occurred in this group. Conclusions: Minimally invasive LLIF/OLIF can significantly improve the coronal and sagittal balance of adult degenerative scoliosis. Staged minimally invasive surgery can significantly alleviate pain and improve function in these patients.

RESUMO

AIMS: The aim of this study was to assess whether supine flexibility predicts the likelihood of curve progression in patients with adolescent idiopathic scoliosis (AIS) undergoing brace treatment. METHODS: This was a retrospective analysis of patients with AIS prescribed with an underarm brace between September 2008 to April 2013 and followed up until 18 years of age or required surgery. Patients with structural proximal curves that preclude underarm bracing, those who were lost to follow-up, and those who had poor compliance to bracing (<16 hours a day) were excluded. The major curve Cobb angle, curve type, and location were measured on the pre-brace standing posteroanterior (PA) radiograph, supine whole spine radiograph, initial in-brace standing PA radiograph, and the post-brace weaning standing PA radiograph. Validation of the previous in-brace Cobb angle regression model was performed. The outcome of curve progression post-bracing was tested using a logistic regression model. The supine flexibility cut-off for curve progression was analyzed with receiver operating characteristic curve. RESULTS: A total of 586 patients with mean age of 12.6 years (SD 1.2) remained for analysis after exclusion. The baseline Cobb angle was similar for thoracic major curves (31.6° (SD 3.8°)) and lumbar major curves (30.3° (SD 3.7°)). Curve progression was more common in the thoracic curves than lumbar curves with mean final Cobb angles of 40.5° (SD 12.5°) and 31.8° (SD 9.8°) respectively. This dataset matched the prediction model for in-brace Cobb angle with less mean absolute error in thoracic curves (0.61) as compared to lumbar curves (1.04). Reduced age and Risser stage, thoracic curves, increased pre-brace Cobb angle, and reduced correction and flexibility rates predicted increased likelihood of curve progression. Flexibility rate of more than 28% has likelihood of preventing curve progression with bracing. CONCLUSION: Supine radiographs provide satisfactory prediction for in-brace correction and post-bracing curve magnitude. The flexibility of the curve is a guide to determine the likelihood for brace success. Cite this article: Bone Joint J 2020;102-B(2):254-260.

RESUMO

AIMS: Idiopathic scoliosis is the most common spinal deformity in adolescents and children. The aetiology of the disease remains unknown. Previous studies have shown a lower bone mineral density in individuals with idiopathic scoliosis, which may contribute to the causation. The aim of the present study was to compare bone health in adolescents with idiopathic scoliosis with controls. METHODS: We included 78 adolescents with idiopathic scoliosis (57 female patients) at a mean age of 13.7 years (8.5 to 19.6) and 52 age- and sex-matched healthy controls (39 female patients) at a mean age of 13.8 years (9.1 to 17.6). Mean skeletal age, estimated according to the Tanner-Whitehouse 3 system (TW3), was 13.4 years (7.4 to 17.8) for those with idiopathic scoliosis, and 13.1 years (7.4 to 16.5) for the controls. Mean Cobb angle for those with idiopathic scoliosis was 29° (SD 11°). All individuals were scanned with dual energy x-ray absorptiometry (DXA) and peripheral quantitative CT (pQCT) of the left radius and tibia to assess bone density. Statistical analyses were performed with independent-samples t-test, the Mann-Whitney U test, and the chi-squared test. RESULTS: Compared with controls, adolescents with idiopathic scoliosis had mean lower DXA values in the left femoral neck (0.94 g/cm2 (SD 0.14) vs 1.00 g/cm2 (SD 0.15)), left total hip (0.94 g/cm2 (SD 0.14) vs 1.01 g/cm2 (SD 0.17)), L1 to L4 (0.99 g/cm2 (SD 0.15) vs 1.06 g/cm2 (SD 0.17)) and distal radius (0.35 g/cm2 (SD 0.07) vs 0.39 g/cm2 (SD 0.08; all p ≤ 0.024), but not in the mid-radius (0.72 g/cm2 vs 0.74 g/cm2; p = 0.198, independent t-test) and total body less head (1,559 g (SD 380) vs 1,649 g (SD 492; p = 0.0.247, independent t-test). Compared with controls, adolescents with idiopathic scoliosis had lower trabecular volume bone mineral density (BMD) on pQCT in the distal radius (184.7 mg/cm3 (SD 40.0) vs 201.7 mg/cm3 (SD 46.8); p = 0.029), but not in other parts of the radius or the tibia (p ≥ 0.062, Mann-Whitney U test). CONCLUSION: In the present study, idiopathic scoliosis patients seemed to have lower BMD at central skeletal sites and less evident differences at peripheral skeletal sites when compared with controls.

RESUMO

AIMS: It is uncertain whether instrumented spinal fixation in nonambulatory children with neuromuscular scoliosis should finish at L5 or be extended to the pelvis. Pelvic fixation has been shown to be associated with up to 30% complication rates, but is regarded by some as the standard for correction of deformity in these conditions. The incidence of failure when comparing the most caudal level of instrumentation, either L5 or the pelvis, using all-pedicle screw instrumentation has not previously been reported. In this retrospective study, we compared nonambulatory patients undergoing surgery at two centres: one that routinely instrumented to L5 and the other to the pelvis. METHODS: In all, 91 nonambulatory patients with neuromuscular scoliosis were included. All underwent surgery using bilateral, segmental, pedicle screw instrumentation. A total of 40 patients underwent fusion to L5 and 51 had their fixation extended to the pelvis. The two groups were assessed for differences in terms of clinical and radiological findings, as well as complications. RESULTS: The main curve (MC) was a mean of 90° (40° to 141°) preoperatively and 46° (15° to 82°) at two-year follow-up in the L5 group, and 82° (33° to 116°) and 19° (1° to 60°) in the pelvic group (p < 0.001 at follow-up). Correction of MC and pelvic obliquity (POB) were statistically greater in the pelvic group (p < 0.001). There was no statistically significant difference in the operating time, blood loss, or complications. Loss of MC correction (> 10°) was more common in patients fixated to the pelvis (23% vs 3%; p = 0.032), while loss of pelvic obliquity correction was more frequent in the L5 group (25% vs 0%; p = 0.007). Risk factors for loss of correction (either POB or MC) included preoperative coronal imbalance (> 50 mm, odds ratio (OR) 11.5, 95%confidence interval (CI) 2.0 to 65; p = 0.006) and postoperative sagittal imbalance (> 25 mm, OR 11.0, 95% CI1.9 to 65; p = 0.008). CONCLUSION: We found that patients undergoing pelvic fixation had a greater correction of MC and POB. The rate of complications was not different. Preoperative coronal and postoperative sagittal imbalance were associated with increased risks of loss of correction, regardless of extent of fixation. Therefore, we recommend pelvic fixation in all nonambulatory children with neuromuscular scoliosis where coronal or sagittal imbalance are present preoperatively.

RESUMO

AIMS: Intraoperative 3D navigation (ION) allows high accuracy to be achieved in spinal surgery, but poor workflow has prevented its widespread uptake. The technical demands on ION when used in patients with adolescent idiopathic scoliosis (AIS) are higher than for other more established indications. Lean principles have been applied to industry and to health care with good effects. While ensuring optimal accuracy of instrumentation and safety, the implementation of ION and its associated productivity was evaluated in this study for AIS surgery in order to enhance the workflow of this technique. The aim was to optimize the use of ION by the application of lean principles in AIS surgery. METHODS: A total of 20 consecutive patients with AIS were treated with ION corrective spinal surgery. Both qualitative and quantitative analysis was performed with real-time modifications. Operating time, scan time, dose length product (measure of CT radiation exposure), use of fluoroscopy, the influence of the reference frame, blood loss, and neuromonitoring were assessed. RESULTS: The greatest gains in productivity were in avoiding repeat intraoperative scans (a mean of 248 minutes for patients who had two scans, and a mean 180 minutes for those who had a single scan). Optimizing accuracy was the biggest factor influencing this, which was reliant on incremental changes to the operating setup and technique. CONCLUSION: The application of lean principles to the introduction of ION for AIS surgery helps assimilate this method into the environment of the operating theatre. Data and stakeholder analysis identified a reproducible technique for using ION for AIS surgery, reducing operating time, and radiation exposure.

RESUMO

Objective: To compare and analyze the correlations between thumb ossification composite index (TOCI), Risser sign and digital skeletal age (DSA) scores and to verify the possibility of TOCI as a supplementary to Risser sign in the evaluation of growth potential of adolescent idiopathic scoliosis (AIS) patients. Methods: Forty-nine AIS patients undergoing bracing treatment between May 2006 and May 2014 were selected from Nanjing Drum Tower Hospital. The follow-up interval was 4-6 months. The following data at each visit were routinely collected, including TOCI and DSA scores, as well as chronologic age and standing height. The height velocity (HV) at each visit was calculated based on the above data. All results were analyzed by Spearman correlation with TOCI and Risser sign. Results: There were strong correlations between TOCI and Risser sign and DSA scores (r=0.962, 0.813, both P<0.01). In AIS patients whose Risser sign were 0-1, the correlation between TOCI and DSA scores was more pronounced, compared with the correlation between Risser sign and DSA scores (0.918 vs 0.792, P<0.01). The HV averaged (7.1±2.1) cm/year in TOCI 5, significantly larger than these in other TOCI scores (all P<0.01). Conclusions: The TOCI 5 can be a sign of high height velocity and high growth potential in AIS patients. TOCI is a valid indicator of skeletal maturity evaluation and can be used as a helpful supplementary to Risser sign, whose predictive ability may be better than Risser sign.

RESUMO

BACKGROUND: It is understood that an effective brace therapy requires a primary curve angle reduction of 50% after administering the first orthotic brace. OBJECTIVES: The aim of the study was to determine the efficacy of conservative brace therapy for scoliosis with a curve angle above 20° and to determine possible influencing factors. MATERIALS AND METHODS: The current study included a cohort of 110 scoliosis patients with conservative brace therapy. The development of the scoliotic curve during brace therapy was documented for an average of 40 months. Influencing factors such as the initial Risser sign, age at the start of treatment, gender, curve patterns and body mass index were analyzed. RESULTS: The collective consisted of 88 patients with idiopathic and 22 with neuromuscular spinal deformities. At the beginning of the brace therapy, the average age was 12.2 ± 2.8 years with a mean scoliosis curve angle of 30.4°â€¯± 12.5°. The primary brace reduced the scoliotic curve by 31% to 20.9°. In children and adolescents with lower maturity status, the success of the brace therapy was greater than in patients with a higher Risser sign. In addition, children with obesity had less success during brace therapy than normal- or underweight children. CONCLUSIONS: The initial curvature correction of 50% required for effective brace therapy could only be achieved in one third of the patients. On average, the correction was 31%.

RESUMO

AIMS: The aim of this study was to compare the surgical and quality-of-life outcomes of children with skeletal dysplasia to those in children with idiopathic early-onset scoliosis (EOS) undergoing growth-friendly management. PATIENTS AND METHODS: A retrospective review of two prospective multicentre EOS databases identified 33 children with skeletal dysplasia and EOS (major curve ≥ 30°) who were treated with growth-friendly instrumentation at younger than ten years of age, had a minimum two years of postoperative follow-up, and had undergone three or more lengthening procedures. From the same registries, 33 matched controls with idiopathic EOS were identified. A total of 20 children in both groups were treated with growing rods and 13 children were treated with vertical expandable prosthetic titanium rib (VEPTR) instrumentation. RESULTS: Mean preoperative major curves were 76° (34° to 115°) in the skeletal dysplasia group and 75° (51° to 113°) in the idiopathic group (p = 0.55), which were corrected at final follow-up to 49° (13° to 113°) and 46° (12° to 112°; p = 0.68), respectively. T1-S1 height increased by a mean of 36 mm (0 to 105) in the skeletal dysplasia group and 38 mm (7 to 104) in the idiopathic group at the index surgery (p = 0.40), and by 21 mm (1 to 68) and 46 mm (7 to 157), respectively, during the distraction period (p = 0.0085). The skeletal dysplasia group had significantly worse scores in the physical function, daily living, financial impact, and parent satisfaction preoperatively, as well as on financial impact and child satisfaction at final follow-up, than the idiopathic group (all p < 0.05). The domains of the 24-Item Early-Onset Scoliosis Questionnaire (EOSQ24) remained at the same level from preoperative to final follow-up in the skeletal dysplasia group (all p > 0.10). CONCLUSION: Children with skeletal dysplasia gained significantly less spinal growth during growth-friendly management of their EOS and their health-related quality of life was significantly lower both preoperatively and at final follow-up than in children with idiopathic EOS.

RESUMO

Close suction drainage systems are widely used in orthopedics and spine surgeries. There are less studies investigating the outcomes of using subfascial closed suction drains in adolescent patients who had undergone idiopathic scoliosis surgery. We evaluated the outcomes of patients with and without closed suction drainage and to investigate whether close suction drainage is needed after adolescent idiopathic scoliosis (AIS) surgery.We retrospectively investigated 63 patients, who underwent posterior spinal surgery for AIS from January 2015 to January 2018. The patients were divided into the following groups: Groups A (drainage group) and B (nondrainage group). We evaluated the wound drainage (wound oozing), need for transfusion, preoperative and postoperative hemoglobin levels, length of hospital stay, and postoperative blood loss from closed suction drains. Patients' scoliosis was categorized according to the Lenke Classification System for Scoliosis. The level of instrumentations was also evaluated.The median postoperative hemoglobin level was lower in group A than in group B. Postoperatively, group A underwent more blood transfusions than group B. Postoperative hospital stay was also significantly longer in group A than in group B. There was no statistical difference in the infection rate between the two groups.Using drains after AIS surgery increases hospital stay duration, blood transfusion rate and patients' anxiety of drain tube removal. Thus, closed suction drainage may not be suitable after AIS surgery.

RESUMO

OBJECTIVE: Introduction: According to the data of the national statistics, the disease of the musculoskeletal system among the teenagers takes the third place among the main types of diseases. So, we decided to analyze and study the connection between the idiopathic scoliosis of the spine and dentognathic anomalies in children aged 12-15 years old in Uzhhorod (Ukraine). The aim: To determine the characteristic violations of the dentognathic system in adolescents with idiopathic scoliosis of the spine, taking into account the anatomical type of lesion. PATIENTS AND METHODS: Materials and methods: 225 people were examined, including 190 girls and 35 boys. All patients were under the control of an orthopedic physician. RESULTS: Results: The most common type of scoliosis is found to be thoracolumbar, which is noted in 114 patients. As a result of analysis it was found that the most characteristic disorders of the dentognathic system in patients with thoracolumbar scoliosis were distal bite (80 ± 2.0%), sagittal gap (37.5 ± 2.1%), deep bite (22.5 ± 2.3%). In the group of healthy children, without scoliosis, the prevalence of dentognathic anomalies is 2.6 times lower than in patients with idiopathic adolescent scoliosis. CONCLUSION: Conclusions: Regardless of the localization of deformation in the spine under scoliosis, all the groups of patients are characterized by the following signs: sagittal gap, shortening of the upper dentition, distal bite, crowding of the teeth on the lower jaw.

RESUMO

Objective: To evaluate the radiographic and clinical outcomes of sequential correction based on satellite rod technique in degenerative scoliosis (DS) with B-type coronal imbalance, and to investigate the efficacy of sequential correction in this cohort. Methods: Twenty-one DS patients with B-type coronal imbalance applying sequential correction from December 2015 to July 2017 in Nanjing Drum Tower Hospital were retrospectively reviewed. There were 4 males and 17 females in this group, the average age was (63±8) years. The coronal parameters including Cobb angle of main curve and distance between C(7) plumb line and center sacral vertical line (C(7)PL-CSVL), as well as sagittal parameters including global kyphosis (GK) and sagittal vertical axis (SVA) were assessed pre-operatively, post-operatively and at the last follow-up. The Scoliosis Research Society-22 (SRS-22) questionnaire was fulfilled before the operation and at each follow-up to evaluate the quality of life. Paired t test was performed for statistical analysis. Results: The patients were followed-up for (20±8) months. The post-operative Cobb angle of main curve was significantly improved from 52°±12° to 19°±7° (t=13.886, P<0.01), and it was 19°±8° at the last follow-up and no significant correction loss was attained (t=1.101, P=0.284). The values of C(7)PL-CSVL before the operation, after the operation and at the final follow-up were (46±11) mm, (12±7) mm and (12±7) mm, respectively; significant post-operative improvement achieved (t=19.718, P<0.01) while there was no correction loss at last follow-up (t=-1.393, P=0.179). After sequential correction, 20 patients (95.2%) improved to A-type coronal imbalance while 1 patient (4.8%) remained with B-type coronal imbalance. Significant post-operative improvements were found in terms of GK and SVA and no significant correction loss was found during follow-up. The scores of pain and self-image showed significant improvement at the last follow-up (t=8.706, 3.104, both P<0.01). In addition, there was no implant failure during follow-up. Conclusion: The sequential correction based on satellite rod technique in DS patients with B-type coronal imbalance corrects the deformity, relieves the clinical symptoms, improves the quality of life, and decreases the rates of post-operative coronal imbalance as well as implant-related complications.

RESUMO

Las escoliosis graves plantean dificultades y complicaciones en su resolución, en particular cuando se presentan con bajo peso, comorbilidades, edad temprana y/o por causas neurológicas o congénitas. Las técnicas mini-invasivas con anclaje bipolar se ha propuesto en los últimos años como una alternativa de tratamiento. OBJETIVO: Presentar las características y resultados en estos pacientes operados en el Hospital El Cruce con técnica mini-invasiva de estabilización con anclaje bipolar. METODOLOGÍA: Se evaluaron pacientes operados por escoliosis con técnica bipolar modificada en el Hospital El Cruce. La misma consistió en abordaje cefálico y caudal de 2 a 3 vértebras, con instrumentación de las mismas y fijación a barras previamente deslizadas en forma intramuscular paravertebral uniendo los dos abordajes. RESULTADOS: Se evaluaron cuatro pacientes intervenidos con técnica bipolar. Edad 11,5 años, dos mujeres. Tres silla-dependientes (neuromusculares) y uno congénito. Peso 27,5 kg (19-40). Tres curvas sinistroconvexa. El Cobb pasó de 105º a 45º.Tiempo de cirugía 187 minutos. La fijación fue en todas tóracolumbar y en un caso incluyó la pelvis. La media de vértebras incluidas fue de 14.Una paciente presentó complicaciones mayores resueltas durante la internación. CONCLUSIONES:La técnica bipolar impresiona una alternativa válida en pacientes con escoliosis graves de bajo peso, temprana edad, comorbilidades y etiologías no idiopáticas.


Severe scoliosis raises difficulties and complications in its resolution, particularly when they present with low weight, comorbidities, early age and / or due to neurological or congenital causes. Minimally invasive techniques with bipolar anchoring have been proposed in recent years as an alternative treatment. OBJECTIVE: is to present the characteristics and results in patients that had surgery at El Cruce Hospital with a minimally invasive technique of stabilization with bipolar anchoring. METHODS:We evaluated patients operated on scoliosis with a modified bipolar technique at El Cruce Hospital.It consisted of a cephalic and a caudal approach of 2 to 3 vertebrae,with instrumentation and anchoring ofthose vertebrae to rods previously sliced in a paravertebral intramuscular form by joining the two approaches. RESULTS:Four patients were evaluated using bipolar technique. Average age 11.5, 2 women. Three chair-dependents (neuromuscular) and one congenital. Weight 27.5 kg (19-40). Three curves were left sided. The Cobb went from 105º to 45º. Surgery time 187 minutes), fixation was in all thoracolumbar and in one case included the pelvis. The mean included vertebrae were 14. A patient with major complications resolved during hospitalization. CONCLUSIONS: The bipolar technique seems to be a valid alternative in patients with severe low-weight scoliosis, early age, comorbidities and nonidiopathic etiologies.

RESUMO

STUDY DESIGN: Retrospective review. BACKGROUND: Inferior facetectomies, with the utilization of segmental pedicle screw constructs for corrective fixation, can provide adequate flexibility and post less risk of neural tissue and blood loss. We analyzed outcomes of surgical treatment for adolescent idiopathic scoliosis (AIS) using inferior facetectomies and segmental pedicle screw constructs. We hypothesized that adequate main curve correction and suitable surgical outcomes would be observed using this technique. METHODS: We reviewed 38 AIS patients who underwent inferior facetectomies and segmental pedicle screw constructs by 2 surgeons at a single institution between May 2014 and December 2016. Coronal and sagittal radiographic measurements were evaluated over 1-year follow-up by 2 trained observers not associated with the surgeries. Surgical details, complications, and hospital length of stay (LOS) were also recorded. RESULTS: Mean fusion levels were 11.0 ±â€Š1.7. The mean Cobb angle of main AIS curves improved from 48.6±â€Š10.1 degree preoperatively to 11.8±â€Š6.2 degree postoperatively and 12.4±â€Š6.2 degree at 1-year follow-up, which percentage correction was 75.9% and 74.6%, respectively. The mean thoracic kyphosis (T5-12) angle was 20.7±â€Š11.6 degree preoperatively, 17.4±â€Š8.0 degree postoperatively, and 16.8±â€Š8.4 degree at 1-year follow-up. The mean surgical time, estimated blood loss, and LOS were 232.4 ±â€Š35.7 minutes, 475.0 ±â€Š169.6 mL, and 3.5 ±â€Š1.3 days. Twelve patients received blood transfusion. There were no neurological or wound complications. CONCLUSIONS: This case series demonstrated adequate correction of main AIS curves, acceptable thoracic kyphosis and blood loss, and short surgical time and LOS in AIS patients treated with inferior facetectomies and segmental pedicle screw constructs, potentially indicating that inferior facetectomies are adequate and suitable for AIS surgery when segmental pedicle screw constructs are utilized.

RESUMO

We aimed to clarify the position of the spinal cord relative to the vertebra in patients with Lenke type 1 adolescent idiopathic scoliosis (AIS). In all, 35 patients with Lenke type 1 AIS who underwent posterior spinal fusion using a pedicle screw construct and preoperative computed tomography (CT) after myelography were recruited. The following radiological parameters were measured on preoperative CT myelography: spinal cord-vertebral (SV) angle, entry-spinal cord distance (ESD), ESD-X, ESD-Y, spinal cord-pedicle (SP) angle, and rotation angle (RAsag). The SV and SP angles were the smallest at T9 level, followed by T8 and T7 levels, and tended to increase cranially and caudally. The ESD was the shortest at T9 level, followed by T8 and T10 levels. The ESD-X was the smallest at T9 level, followed by T8 level, while the ESD-Y was the smallest at T10 level, followed by T9 and T8 levels. Mean RAsag increased from T4 to T9 levels and decreased from T9 to T12 levels. The ESD was significantly negatively correlated to RAsag. Among all apical vertebrae, the SV and SP angles were negatively correlated to Cobb angle. The RAsag was positively correlated while the ESD was negatively correlated to the Cobb angle. The spinal cord is close to the vertebrae in the apical vertebral region and far from the vertebrae at the upper and lower thoracic vertebral levels in AIS. Therefore, the potential risk of spinal cord injury by pedicle screw is the highest in the apical vertebral region.

RESUMO

AIMS: The aim of this study was to determine the influence of pelvic parameters on the tendency of patients with adolescent idiopathic scoliosis (AIS) to develop flatback deformity (thoracic hypokyphosis and lumbar hypolordosis) and its effect on quality-of-life outcomes. PATIENTS AND METHODS: This was a radiological study of 265 patients recruited for Boston bracing between December 2008 and December 2013. Posteroanterior and lateral radiographs were obtained before, immediately after, and two-years after completion of bracing. Measurements of coronal and sagittal Cobb angles, coronal balance, sagittal vertical axis, and pelvic parameters were made. The refined 22-item Scoliosis Research Society (SRS-22r) questionnaire was recorded. Association between independent factors and outcomes of postbracing ≥ 6° kyphotic changes in the thoracic spine and ≥ 6° lordotic changes in the lumbar spine were tested using likelihood ratio chi-squared test and univariable logistic regression. Multivariable logistic regression models were then generated for both outcomes with odds ratios (ORs), and with SRS-22r scores. RESULTS: Reduced T5-12 kyphosis (mean -4.3° (sd 8.2); p < 0.001), maximum thoracic kyphosis (mean -4.3° (sd 9.3); p < 0.001), and lumbar lordosis (mean -5.6° (sd 12.0); p < 0.001) were observed after bracing treatment. Increasing prebrace maximum kyphosis (OR 1.133) and lumbar lordosis (OR 0.92) was associated with postbracing hypokyphotic change. Prebrace sagittal vertical axis (OR 0.975), prebrace sacral slope (OR 1.127), prebrace pelvic tilt (OR 0.940), and change in maximum thoracic kyphosis (OR 0.878) were predictors for lumbar hypolordotic changes. There were no relationships between coronal deformity, thoracic kyphosis, or lumbar lordosis with SRS-22r scores. CONCLUSION: Brace treatment leads to flatback deformity with thoracic hypokyphosis and lumbar hypolordosis. Changes in the thoracic spine are associated with similar changes in the lumbar spine. Increased sacral slope, reduced pelvic tilt, and pelvic incidence are associated with reduced lordosis in the lumbar spine after bracing. Nevertheless, these sagittal parameter changes do not appear to be associated with worse quality of life. Cite this article: Bone Joint J 2019;101-B:1370-1378.

RESUMO

Objective: To measure the length changes of the spine canal of patients with severe kyphosis after treatments of deformity using osteotomy surgeries. Methods: Retrospectively investigated the data of 10 severe kyphosis patients who were treated between August of 2016 and December of 2018 at Beijing Chaoyang Hospital (5 with Ponte and 5 with posterior vertebra column resection (VCR) osteotomy surgeries). For each patient, the full-spine X-Ray images were used to measure Cobb angles before and after the surgery; 3D CT images were used to construct a 3D model of the spine, including the T(2) to L(2) vertebrae and the spine canal. The 3D model was then used to measure the spinal canal lengths (SCLs) between the upper and lower vertebrae (U/LEV) and between T(2)-L(2) vertebrae at 5 locations on the spine canal cross section (anterior, central, posterior, left and right locations), and the vertical distance between the T(2) and L(2) vertebrae before and after the surgery. The data were statistically analyzed using t tests. Results: For the 5 patients of Ponte osteotomy, the Cobb angles were improved by 89°±17°(56%±11%) and 84°±16°(56%±8%) in the coronal and sagittal planes respectively after the surgery. The changes of the SCL between the T(2)-L(2) vertebrae were (9.9±4.8) mm and (6.0±12.7) mm, and those were (7.2±5.4) mm and (-0.5±7.9) mm between the U/LEV, respectively at the concave and convex sides of the canal. The vertical distance between the T(2)-L(2) vertebrae increased by (66.1±12.0) mm. For the 5 patients with VCR osteotomy, the Cobb angles improved by 83°±19°(60%±10%) and 82°±22°(56%±10%) in the coronal and sagittal planes, respectively. The changes of the SCL between the T(2)-L(2) vertebrae were (-5.5±5.3) mm and (-14.0±6.6) mm, and those were (-8.3±8.4) mm and (-20.7±11.6) mm between the U/LEV, respectively at the concave and the convex sides of the canal. The vertical distance between the T(2)-L(2) vertebrae increased by (41.5±12.4) mm. Conclusions: The Ponte osteotomy significantly elongates the SCLs, especially at the concave side, and the VCR osteotomy shortens the spinal canal, resulting in significant compression of the spinal cord at the convex side.

RESUMO

Objective: To investigate the clinical outcomes of one-stage posterior correction surgery and second-stage anterior debridement and fusion in treating children with thoracic tuberculosis complicated with kyphoscoliosis. Methods: From January 2008 to December 2014, a total of 17 children with thoracic vertebral tuberculosis complicated with kyphoscoliosis who underwent a one-stage posterior correction and second-stage anterior debridement and complementary fusion were included. There were 8 males and 9 females with an average age of (8±4) years (5-14 years). All patients underwent posterior correction and anterior debridement and bone graft fusion surgery. The neurological function was determined by Frankel grade. The operation time, estimated blood loss (EBL), levels fused and numbers of screws were recorded. The following radiographic parameters were measured: Cobb angle of the coronal curve, regional kyphosis and sagittal vertical axis (SVA). The incidence of intraoperative and postoperative complications was recorded. The data before and after the operation were compared with paired sample t test. Results: The tuberculosis lesions located in the thoracic vertebrae, and the abscess involved 2 to 4 vertebral segments. The average operation time was (4.1±0.8) h, the EBL was (526±275) ml, the levels fused were 7.6±2.3, and 173 pedicle screws were placed. The preoperative coronal curve averaged 12.6°±6.2°, and it was corrected to 4.2°±1.9° postoperatively (t=4.628, P<0.01), the regional kyphosis was 67.2°±19.4°, and it was corrected to 15.7°±8.2° postoperatively (t=8.192, P<0.01). The SVA improved from (8.1±5.0) mm to (3.0±1.7) mm postoperatively. The mean duration of follow-up for all the patients were (38±11) months. At final follow-up, SVA was reduced to (2.4±2.0) mm and the other parameter kept stable. Thirteen patients had more than one grade improvement of Frankel grade. The VAS score for all patients improved from 4.7±2.8 to 2.2±0.5 postoperatively (t=3.973, P=0.01), and improved to 0.5±0.5 at final follow-up (t=-7.880, P<0.01). No recurrence of primary spinal tuberculosis was seen at final follow-up of all patients. Conclusions: One-stage posterior correction and second-stage anterior complementary debridement and fusion is an effective procedure for children with thoracic tuberculosis complicated with kyphoscoliosis. Significant postoperative deformity correction could be achieved with satisfactory improvement of neurological function. Solid fusion and satisfactory correction maintenance were observed at mid-to long-term follow-up.
