Abstract Objective The aim of this study was to evaluate the GSH effect on functional and histological recovery after experimental spinal cord injury in rats. Methods Forty Wistar rats were subjected to spinal cord injury through the Multicenter Animal Spinal Cord Injury Study (MASCIS) Impactor system. The rats were sorted and divided into four groups, as follows: Group 1 ‒ Laminectomy and spinal cord injury; Group 2 ‒ Laminectomy, spinal cord injury and Saline Solution (SS) 0.9%; Group 3 ‒ Laminectomy, spinal cord injury, and GSH; and Group 4 ‒ lLaminectomy without spinal cord injury. GSH and SS were administered intraperitoneally. Groups 1 and 4 received no intervention. Results The rats were evaluated for locomotor function recovery at seven different times by the Basso, Beattie, and Bresnahan (BBB) scale on days 2, 7, 14, 21, 28, 35, and 42 after the spinal cord injury. On day 42, the rats were sacrificed to analyze the histological findings of the injured spinal cord. In the group submitted to GSH, our experimental study revealed better functional scores on the BBB scale, horizontal ladder scale, and cranial and caudal axon count. The differences found were statistically significant in BBB scores and axonal count analysis. Conclusion This study demonstrated that using glutathione in experimental spinal trauma can lead to better functional recovery and improved axonal regeneration rate in Wistar rats submitted to experimental spinal cord injury.

Abstract Study design Experimental study utilizing with a standardized model (MASCIS Impactor) of Spinal Cord Injury (SCI) in Balb C mouse model with implantation of mononuclear stem cells derived from the human umbilical cord and placenta blood in the early chronic phase of SCI. Objectives The aim of this study was to evaluate the nerve regeneration and motor functional recovery in Balb C mice with surgically induced paraplegia in response to the use of mononuclear stem cells, in early chronic phase (> 2 weeks and < 6 months), because there is yet potential of neuronal and functional recovery as the neuronal scar is not still completely established. Methods Forty-eight mice were randomly assigned to 6 groups of 8 animals. Group 1 received the stem cells 3 weeks after the trauma, and Group 2 received them six weeks later. In Group 3, saline solution was injected at the site of the lesion 3 weeks after the trauma, and in Group 4, 6 weeks later. Group 5 underwent only spinal cord injury and Group 6 underwent laminectomy only. The scales used for motor assessment were BMS and MFS for 12 weeks. Results The intervention groups showed statistically significant motor improvement. In the histopathological analysis, the intervention groups had a lower degree of injury (p < 0.05). Regarding axonal budding, the intervention groups showed increasing in axonal budding in the caudal portion (p < 0.05). Conclusions The use of stem cells in mice in the chronic phase after 3 and 6 weeks of SCI brings functional and histopathological benefits to them.

ABSTRACT Objective: To determine the epidemic profile of patients with spinal fractures referred for evaluation by Spine Group of IOT-HCFMUSP between 2019 and 2022. To enable the effect of the Covid-19 Pandemic on these epidemic profiles. Methods: We retrospectively analyzed the medical records of patients with spinal fractures referred by the São Paulo Center for the Regulation of Health Offers and Services (CROSS) to the Spine Group of IOT-HCFMUSP between 2019 and 2022. The epidemiological profile between the pre-pandemic Covid-19 period and the period of the Covid-19 pandemic until December 2022 in the city of São Paulo was compared. Results: The medical records of 427 patients were analyzed between March 2019 and December 2022. During the period, males accounted for 71.9% of cases, and the mean age was 46.7 years. Falls from heights were the most frequent trauma mechanism (63.7%), followed by motorcycle accidents (14.3%). The absence of neurological deficit occurred in 76.8% of the cases, and the most injured region was the lumbar region (39.3%). There were changes in the epidemiological profile during the Covid-19 pandemic compared to the pre-pandemic. Conclusions: A predominance of middle-aged males was observed, in addition to the trauma mechanism of falling from a height, as well as the absence of a neurological deficit in the initial evaluation. The lumbar and cervical regions were the most frequent sites of injury. The pandemic period interfered with the epidemiological profile presented and in the time interval between the injury and the evaluation at the IOT-HCFMUSP. Level of Evidence IV; Case Series.

Abstract Objective The aim of this study was to evaluate the best timing and feasibility of intrathecal application of sodium monosialoganglioside (GM1) after spinal cord contusion in Wistar rats as an experimental model. Methods Forty Wistar rats were submitted to contusion spinal cord injury after laminectomy. The animals were randomized and divided into four groups: Group 1 - Intrathecal application of GM1 24 hours after contusion; Group 2 - Intrathecal application of GM1 48 hours after contusion; Group 3 - intrathecal application of GM1 72 hours after contusion; Group 4 - Sham, with laminectomy and intrathecal application of 0.5 mL of 0.9% saline solution, without contusion. The recovery of locomotor function was evaluated at seven different moments by the Basso, Beattie, and Bresnahan (BBB) test. They were also assessed by the horizontal ladder, with sensory-motor behavioral assessment criteria, pre-and postoperatively. Results This experimental study showed better functional scores in the group submitted to the application of GM1, with statistically significant results, showing a mean increase when evaluated on known motor tests like the horizontal ladder and BBB, at all times of evaluation (p < 0.05), especially in group 2 (48 hours after spinal cord injury). Also, fewer mistakes and slips over the horizontal ladder were observed, and many points were achieved at the BBB scale analysis. Conclusion The study demonstrated that the intrathecal application of GM1 after spinal cord contusion in Wistar rats is feasible. The application 48 hours after the injury presented the best functional results.

ABSTRACT Introduction: In March 2020, WHO officially decreed that the world was going through a pandemic, that of Covid-19. In May 2022, in Brazil, the end of measures to deal with the pandemic was decreed. In 2022, there was a movement to return to normal care in the provision of care. Objective: In the present study, we carried out a retrospective descriptive analysis of the epidemiological scenario of the ward of the Spine Group at the Hospital das Clínicas of the Faculty of Medicine of the Universidade de São Paulo (HC-FMUSP). Method: Data analysis was performed from information gathered in patients’ medical records. Results: In the analyzed period, there were 152 consultations in hospitalization, with the main cause being spinal trauma. Of all the cases, only 23.68% were scheduled on an elective basis, which despite being a lower than expected number, was shaped by the demands of urgent care channeled to the service in question. Conclusion: Despite a higher number of cases hospitalized in the post-pandemic period, there is still the expectancy of more elective cases to be treated in the future.

ABSTRACT Objectives: To evaluate the functional and immunohistochemical effects of ganglioside GM1 and erythropoietin following experimental spinal cord injury. Methods: Thirty-two male BALB/c mice were subjected to experimental spinal cord injury using the NYU Impactor device and were randomly divided into the following groups: GM1 group, receiving standard ganglioside GM1 (30 mg/kg); erythropoietin group, receiving erythropoietin (1000 IU/kg); combination group, receiving both drugs; and control group, receiving saline (0.9%). Animals were evaluated according to the Basso Mouse Scale (BMS) and Hindlimb Mouse Function Score (MFS). After euthanasia, the immunohistochemistry of the medullary tissue of mice was analyzed. All animals received intraperitoneal treatment. Results: The GM1 group had higher BMS and MFS scores at the end of the experiment when compared to all other groups. The combination group had higher BMS and MFS scores than the erythropoietin and control groups. The erythropoietin group had higher BMS and MFS scores than the control group. Immunohistochemical tissue analysis showed a significant difference among groups. There was a significant increase in myelinated axons and in the myelinated axon length in the erythropoietin group when compared to the other intervention groups (p < 0.01). Conclusion: Erythropoietin and GM1 have therapeutic effects on axonal regeneration in mice subjected to experimental spinal cord injury, and administration of GM1 alone had the highest scores on the BMS and MFS scales.

RESUMO Objetivos: Avaliar complicações pós-cirúrgicas, incluindo infecções por COVID-19, entre pacientes cirúrgicos numa instituição terciária de saúde durante a pandemia, e desenvolver um perfil epidemiológico local de pacientes de cirurgias da coluna. Métodos: estudo descritivo e retrospectivo de todos os pacientes que passaram por cirurgias da coluna entre março de 2020 e 14 de janeiro de 2021, numa instituição terciária na América Latina. Todos os pacientes que passaram por cirurgias na coluna foram incluídos, sem restrição de idade. Os principais resultados foram complicações pós-cirúrgicas, incluindo a infecção por COVID-19. Resultados: 74 pacientes foram incluídos no estudo, 43 do sexo masculino e 31 do feminino. A média de idade foi de 49.6 anos. A duração média da hospitalização foi de 11.5 dias. Cirurgias urgentes foram realizadas em 60.81% dos casos. Durante a hospitalização, apenas 5 dos 74 pacientes foram diagnosticados com COVID-19, e apenas 1 deles teve envolvimento pulmonar estimado em mais que 50%. Em média, 1,9 desbridamentos cirúrgicos foram necessários após infecção do sítio cirúrgico. Conclusões: Durante o período de hospitalização, apenas 6,37% dos pacientes foram diagnosticados com infeção por COVID-19. A taxa de mortes devido à infecção por COVID-19 foi de 1 em 5. Infecções do sítio cirúrgico atingiram uma taxa de 10.8%, nível similar àquele prévio à pandemia. Nível de evidência IV ; Estudo observacional retrospectivo descritivo .

ABSTRACT Objectives: To assess postoperative complications, including COVID-19 infection, among patients undergoing surgeries at a tertiary institution during the pandemic, and to develop a local epidemiological profile of spine surgery patients. Methods: Retrospective descriptive study of all patients who underwent spine surgery between March 2020 and 14 January 2021 in a tertiary institution in Latin America. All patients who underwent spine surgery were included, without age restrictions. The main outcomes were postoperative complications, including COVID-19 infection. Results: 74 patients were included in the study, 43 males and 31 females. The average age was 49.6 years. The mean duration of hospitalization was 11.5 days. Urgent surgeries were performed in 60.81% of cases. During hospitalization, only 5 of 74 patients were diagnosed with COVID-19, and only 1 patient had pulmonary involvement estimated to be greater than 50%. On average, 1.9 surgical debridements were required after postoperative surgical site infection. Conclusions: During the hospitalization period, only 6.7% of patients were diagnosed with COVID-19 infection. The COVID-19 infection death rate was 1 in 5 cases. The postoperative surgical site infection rate was 10.8%, similar to the level before the pandemic. Level of Evidence IV; Observational retrospective descriptive study .

RESUMO Objetivo: Correlacionar os resultados dos questionários STarT Back Tool e DRAM, aplicados em um único tempo, a uma população com dor lombar. Métodos: Estudo transversal comparativo com 84 participantes portadores de dor lombar baixa submetidos aos questionários STarT Back Screening Tool (SBST) e DRAM. O grau de correlação entre os dois questionários foi analisado pela avaliação dos dados individualizados e do coeficiente de correlação de Spearman. Resultados: De acordo com o DRAM, 19% dos pacientes foram classificados como “normais”, 32,1% “em risco” e 48,8% se enquadraram no subgrupo “distressed”. De acordo com o SBST, 59,5% dos pacientes foram classificados como “baixo risco”, 31% “risco médio” e 9,5% “alto risco”. Ao aplicar o coeficiente de Spearman para avaliar o grau de correlação entre os dois questionários, foi obtido o valor de 0,4. Isso mostra que há uma correlação positiva entre os dois questionários, embora seja considerada correlação fraca (p < 0,001). Conclusão: Há uma correlação positiva entre os dois questionários, porém o DRAM mostrou tendência maior a identificar pacientes com algum grau de transtorno psíquico quando comparado com o SBST. Ambos os questionários são efetivos para identificar esses fatores, mas os dados sugerem que o DRAM talvez seja mais efetivo como ferramenta de triagem em pacientes com dor lombar baixa, em virtude do maior número de doentes identificados. Nível de evidência III; Estudo diagnóstico.

ABSTRACT Objective: To correlate the results of the STarT Back Screening Tool and DRAM questionnaires, applied simultaneously, in a population with low back pain. Methods: Comparative cross-sectional study with 84 participants with low back pain assessed by both STarT Back Screening Tool (SBST) and DRAM questionnaires. The degree of correlation between the two questionnaires was analyzed through the evaluation of individualized data and using the Spearman correlation coefficient. Results: According to the DRAM, 19% of the patients were classified as “normal”, 32.1% as “at risk” and 48.8% as “distressed”. According to SBST, 59.5% of patients were classified as “low risk”, 31% as “medium risk” and 9.5% as “high risk”. Applying the Spearman's coefficient to evaluate the degree of correlation between the two questionnaires, a value of 0.4 was obtained. This shows that there is a positive, but weak, correlation (p <0.001) between the two questionnaires. Conclusion: There is a positive correlation between the two questionnaires, but the DRAM showed a greater tendency to classify patients with some degree of psychological distress when compared to the SBST. Both questionnaires are effective in identifying these factors, but the data suggest that the DRAM may be more effective as a screening tool in patients with low back pain, in view of the higher number of patients identified. Level of evidence III; Diagnostic test study.

RESUMEN Objetivo: Correlacionar los resultados de los cuestionarios STarT Back Tool y DRAM, aplicados de una sola vez, en una población con dolor lumbar. Métodos: Estudio transversal comparativo con 84 participantes con dolor lumbar evaluados por los cuestionarios STarT Back Screening Tool (SBST) y DRAM. El grado de correlación entre los dos cuestionarios se analizó mediante la evaluación de datos individualizados y del coeficiente de correlación de Spearman. Resultados: Según DRAM, el 19% de los pacientes fue clasificado como “normal”, el 32,1% como “ en riesgo” y el 48,8% se encuadró en el subgrupo “distressed”. Según SBST, el 59,5% de los pacientes fue considerado como de “bajo riesgo”, el 31% de “riesgo medio” y el 9,5% de “alto riesgo”. Al aplicar el coeficiente de Spearman para evaluar el grado de correlación entre los dos cuestionarios, se obtuvo un valor de 0,4. Ello demuestra que existe una correlación positiva, pero débil (p <0,001) entre los dos cuestionarios. Conclusión: Existe una correlación positiva entre los dos cuestionarios, pero DRAM mostró una mayor tendencia a identificar pacientes con algún grado de trastorno psicológico en comparación con SBST. Ambos cuestionarios son eficaces para identificar estos factores, pero los datos sugieren que DRAM puede ser más eficaz como herramienta de detección en pacientes con dolor lumbar, debido al mayor número de pacientes identificados. Nivel de evidencia III; Estudio diagnóstico.

OBJECTIVE: In 2020, the COVID-19 pandemic brought a work and stress overload to healthcare workers, increasing their vulnerability to mental health impairments. In response, the authors created the COMVC-19 program. The program offered preventive actions and mental health treatment for the 22,000 workers of The Hospital das Clinicas da Faculdade de Medicina da Universidade de São Paulo (HCFMUSP). This paper aims to describe its implementation and share what we have learned from this experience. METHODS: Workers were able to easily access the program through a 24/7 hotline. Additionally, a mobile phone app that screened for signs and symptoms of emotional distress and offered psychoeducation and/or referral to treatment was made available. Data from both these sources as well as any subsequent psychiatric evaluations were collected. RESULTS: The first 20 weeks of our project revealed that most participants were female, and part of the nursing staff working directly with COVID-19 patients. The most frequently reported symptoms were: anxiety, depression and sleep disturbances. The most common diagnoses were Adjustment, Anxiety, and Mood disorders. CONCLUSIONS: Implementing a mental health program in a multimodal intervention was feasible in a major quaternary public hospital. Our data also suggests that preventive actions should primarily be aimed at anxiety and depression symptoms, with a particular focus on the nursing staff.

RESUMO Objetivo O uso de parafusos pediculares foi um marco para a cirurgia moderna de coluna vertebral. Esse tipo de fixação, devido a sua biomecânica superior, deu maior poder de fixação, maior capacidade de resistir às forças de arrancamento e, portanto, maior estabilidade e menores taxas de pseudoartrose. A fixação da junção lombossacra, mesmo com o desenvolvimento destes novos implantes, permanece um desafio devido, principalmente, às consideráveis taxas de pseudoartrose. O uso de parafusos de ilíaco resolve o problema biomecânico. Entretanto, seu uso mostra elevadas taxas de problemas na ferida operatória. O parafuso de S2-Alar-Ilíaco (S2AI) veio como solução para essas complicações. A falta de estudos acerca dos parâmetros anatômicos e antropométricos na população brasileira justifica o estudo realizado. Métodos Foram analisadas 11 tomografias de bacia de homens brasileiros adultos por 4 avaliadores. Foram considerados os lados direito e esquerdo. Em cada paciente foram feitas medidas de maior e menor comprimento ósseo, maior e menor diâmetro ósseo, distância do ponto de entrada na pele, ângulos sagital e axial relacionadas à hipotética inserção de um parafuso S2AI e comparadas às mesmas medidas obtidas em relação ao parafuso de ilíaco. Resultados O comprimento ósseo médio foi de 136,7 mm, maior diâmetro ósseo foi de 24,8 mm, o menor diâmetro ósseo de 19,7 mm e a distância do parafuso para a pele foi de 42,1 mm para o parafuso S2AI. Conclusão Os dados obtidos apresentam uma média da amostra que podem ser úteis na decisão da técnica cirúrgica no grupo estudado. Nível de evidência I; Estudo Diagnóstico (Investigação Anatômica).

ABSTRACT Objective The use of pedicle screws was a milestone for modern spinal surgery. This type of fixation, due to its superior biomechanics, gave greater fixation power, greater capacity to withstand the pulling forces and, therefore, greater stability and lower rates of pseudoarthrosis. Fixation of the lumbosacral junction, even with the development of these new implants, remains a challenge mainly because the considerable rates of pseudoarthrosis. The use of iliac screws solves the biomechanical difficulties. However, its use shows high rates of surgical wound problems. The S2-Alar-Iliac screw (S2AI) came as a solution to these complications. The lack of studies about anatomical and anthropometric parameters in the Brazilian population justifies the study. Methods Eleven hip tomographies of Brazilian adult males were analyzed by four evaluators. The right and left sides were considered. In each patient, measurements were made of greater and shorter bone length, greater and smaller bone diameter, distance from the entry point to the skin, sagittal and axial angles related to the hypothetical insertion of an S2AI screw and compared to the same measurements obtained with the iliac screw. Results The mean bone length was 136.7 mm, the greatest bone diameter was 24.8 mm, the smallest bone diameter was 19.7 mm and the distance from the screw to the skin was 42.1 mm for the S2AI screw. Conclusions The obtained data present an average of the sample that can be useful in the decision of the surgical technique in the studied group. Level of evidence I; Diagnostic Studies (Anatomical Investigation).

Este tipo de fijación, debido a su biomecánica superior, dio mayor poder de fijación, mayor capacidad de resistir a las fuerzas de tracción y, por lo tanto, mayor estabilidad y menores tasas de pseudoartrosis. La fijación de la unión lumbosacra, incluso con el desarrollo de estos nuevos implantes, sigue siendo un desafío debido principalmente a las considerables tasas de pseudoartrosis. El uso de tornillos ilíacos soluciona el problema biomecánico. Sin embargo, su uso muestra altas tasas de problemas en la herida quirúrgica. El tornillo S2-Alar-Ilíaco (S2AI) vino como solución para estas complicaciones. La falta de estudios sobre los parámetros anatómicos y antropométricos en la población brasileña justifica el estudio realizado. Métodos Se analizaron 11 tomografías de cadera de hombres brasileños adultos por 4 evaluadores, considerando los lados derecho e izquierdo. En cada paciente se realizaron medidas de mayor y menor longitud ósea, mayor y menor diámetro óseo, distancia del punto de entrada en la piel, ángulos sagital y axial relacionados con la inserción hipotética de un tornillo S2AI y comparados a las mismas medidas obtenidas en relación al tornillo ilíaco. Resultados La longitud ósea promedio fue de 136,7 mm, el mayor diámetro óseo fue de 24,8 mm, el diámetro óseo menor de ١٩,٧ mm y la distancia del tornillo a la piel fue de 42,1 mm para el tornillo S2AI. Conclusiones Los datos obtenidos presentan un promedio de la muestra que puede ser útil en la decisión de la técnica quirúrgica en el grupo estudiado.

RESUMO Objetivo: Reportar o uso de duas técnicas (radiocirurgia e vertebrectomia em bloco) no mesmo paciente, para o tratamento de metástases de um hemangiopericitoma intracraniano em dois locais da coluna. Hemangiopericitomas intracranianos são raros, consistindo em cerca de 2,4% dos tumores da meninge e menos de 1% de todos os tumores do sistema nervoso central, e metástases para a coluna são ainda mais raras: as maiores séries de casos publicada tinham 5 e 7 casos. Métodos: Um homem de 37 anos com diagnóstico de hemangiopericitoma intracraniano foi encaminhado para resecção em bloco de lesão metastática em T12 com a técnica de Tomita. Resultados: A doença evoluiu com metástase em T2, tratada com radiocirurgia (dose de 1600 cGy). O paciente morreu 1.706 dias após a resecção em bloco de T12 e 1.324 dias após a radiocirurgia de T2, livre de recorrência nessas localizações, devido a progressão sistêmica da doença (para fígado e sistema nervoso central). Conclusão: Este é o primeiro caso na literatura no qual duas técnicas diferentes foram usadas pra tratar lesões metastáticas da coluna de hemangiopericitoma intracraniano, único pelo uso de duas técnicas de tratamento no mesmo paciente. Nível de evidência V, relato de caso.

ABSTRACT Objective: To report the use of two techniques (radiosurgery and en bloc vertebrectomy) on the same patient for the treatment of two metastases in different sites of the spine arising from intracranial hemangiopericytoma. Intracranial hemangiopericytomas are rare, comprising approximately 2.4% of meningeal tumors and <1% of all tumors of the central nervous system. Metastases to the spine are even rarer: The largest case series reported in the literature has 5 and 7 cases. Methods: A 37-year-old man diagnosed with intracranial hemangiopericytoma was referred for a metastatic lesion in T12 and underwent en bloc resection using the Tomita technique. Results: The disease evolved with a metastasis to T2 treated by radiosurgery with 1600 cGy. The patient died 1,706 days after the en bloc resection of T12 and 1324 days after the radiosurgery of T2, and no recurrence occurred in these locations due to progression of the systemic diseases (liver and central nervous system). Conclusion: This is the first case reported in the literature in which two different techniques were used to treat metastatic lesions in the spine from an intracranial hemangiopericytoma and is unique for its use of two treatments in the same patient. Level of evidence: V, case report

RESUMO Objetivo: A escoliose idiopática do adolescente é caracterizada por deformidade rotacional e lateral da coluna vertebral. A medição da rotação vertebral é importante para o prognóstico e tratamento. Nosso objetivo foi avaliar se o método de Nash-Moe pode ser usado para medir a correção da deformidade axial com o tratamento cirúrgico usando a manobra de derotação em ambos os ápices e extremidades da deformidade em pacientes com EIA. Métodos: A rotação foi avaliada usando os critérios de Nash e Moe em radiografias pré e pós-operatórias. Também avaliamos a severidade no plano coronal pelo método de Cobb, a razão de correção alcançada, a densidade do parafuso e o número de vértebras envolvidas na instrumentação. Resultados: A correção do método de Cobb foi de 54,8%. Quando desconsideramos vértebras que apresentavam grau 0 no pré-operatório de Nash-Moe, encontramos, em média, 54,5% de correção mensurável na primeira vértebra não instrumentada acima, 69,2% na primeira vértebra instrumentada, 32,2% na vértebra apical, 36,8% na última vértebra instrumentada e 30% na primeira vértebra não instrumentada abaixo. Em nosso estudo, ٣٢,١٤٪ dos pacientes apresentaram uma correção mensurável na vértebra apical. Conclusão: No plano axial, a correção pode ser avaliada satisfatoriamente pelo método de Nash-Moe. Nível de Evidência VI. Série de casos.

ABSTRACT Objective: Adolescent idiopathic scoliosis (AIS) is characterized by rotational and lateral deformity of the spine. The measurement of vertebral rotation is important for prognosis and treatment. Our objective was to evaluate whether the Nash-Moe method can be used to measure axial deformity correction with surgical treatment using the rod derotation maneuver at both the apex and extremities of the deformity in patients with AIS. Methods: Rotation was assessed using the Nash and Moe criteria, on preoperative and postoperative radiographs. We also evaluated the severity on the coronal plane using the Cobb method, ratio of correction achieved, screw density, and number of vertebrae involved in the instrumentation. Results: The Cobb method correction average was 54.8%. When we disregarded vertebrae that presented preoperative Nash-Moe grade 0, the average measurable correction was 54.5% in the first non-instrumented vertebra above, 69.2% in the first instrumented vertebra, 32.2% in the apical vertebra, 36.8% in the last instrumented vertebra, and 30% in the first non-instrumented vertebra below. In our study, 32.14% of the patients presented a measurable correction in the apical vertebra. Conclusion: On the axial plane, correction can be satisfactorily evaluated using the Nash-Moe method. Level of Evidence VI. Case Series.
