ABSTRACT

ABSTRACT Objective: There is still no consensus as to the treatment options for thoracolumbar burst fractures, although these fractures are widely described in the literature. The aim of this study was to evaluate the clinical and radiological outcomes of percutaneous instrumentation without arthrodesis as a method of fixation of these lesions. Methods: This retrospective, cross-sectional study evaluated 16 patients by measuring regional kyphosis using the Cobb method and the scores for quality of life and return to work (Oswestry Disability Index, VAS, SF-36 and Denis). Results: Six months after surgical treatment, 62.5% of all patients showed minimal disability according to the Oswestry Disability Index, maintenance of regional kyphosis correction and no synthesis failure. Conclusions: The clinical and radiological outcomes of the study suggest that minimally invasive fixation is indicated for the treatment of thoracolumbar burst fractures. Level of evidence IV; Observational study: retrospective cohort.


RESUMO Objetivo: As fraturas toracolombares do tipo explosão, embora amplamente descritas na literatura, permanecem sem consenso quanto às modalidades de tratamento. O objetivo do presente estudo foi avaliar os resultados clínicos e radiológicos da instrumentação percutânea sem artrodese como método de fixação dessas lesões. Métodos: O estudo transversal retrospectivo avaliou 16 pacientes por meio da aferição da cifose regional pelo método de Cobb e dos escores de qualidade de vida e retorno ao trabalho (Índice de Incapacidade de Oswestry, EVA, SF-36 e Denis). Resultados: Seis meses depois do tratamento cirúrgico, verificou-se 62,5% dos pacientes com incapacidade mínima segundo o Índice de Incapacidade Oswestry, manutenção da correção da cifose regional e ausência de falha da síntese. Conclusões: Os desfechos clínicos e radiológicos do estudo sugerem que a fixação minimamente invasiva é relevante para o tratamento das fraturas toracolombares do tipo explosão. Nível de evidência IV; Estudo observacional: coorte retrospectiva.

ABSTRACT

ABSTRACT Objective To describe the spinopelvic parameters in patients with conservatively treated thoracolumbar burst fractures. Methods Twenty-six patients with thoracolumbar burst fractures treated conservatively between 2008 and 2017 participated in the study. Inclusion criteria were acute burst-type fractures, located between T11 and L2, which compromised a single vertebral segment, did not present a neurological deficit, and had a minimum of 6 months of follow-up, excluding injuries that presented distraction or rotation, pathological fractures, and surgically treated cases. The sagittal and spinopelvic alignment parameters, including vertical sagittal axis, sacral slope, pelvic tilt, pelvic incidence, lumbar lordosis, and regional kyphosis, were analyzed. Results The values obtained for the sample showed that there was an increase in regional kyphosis and that the mean sagittal parameters and lumbar lordosis were within the values considered normal in the literature. Conclusion Patients with thoracolumbar burst fractures treated conservatively had no alterations in the spinopelvic parameters. Level of Evidence II; Retrospective study.

ABSTRACT

QUESTION: In adolescents with idiopathic scoliosis, does combined aerobic and resistance training improve respiratory function, perceived exertion and functional exercise capacity more than aerobic training only? DESIGN: Randomised controlled trial with concealed allocation, blinded assessors and intention-to-treat analysis. PARTICIPANTS: Forty adolescents with idiopathic scoliosis and formal indication for surgical correction (spinal curvature ≥ 45 deg). INTERVENTION: Both groups undertook three 60-minute training sessions per week for 12 weeks. The experimental group performed combined aerobic and resistance training and the control group performed only aerobic training. OUTCOME MEASURES: At baseline and upon completion of treatment, participants completed: a 6-minute walk test with Borg scale (0 to 10) rating of exertion, spirometry, maximal respiratory pressures and peak expiratory flow measurement. RESULTS: After 12 weeks of training, the experimental group improved more than the control group on the 6-minute walk test (MD 22 m, 95% CI 4 to 40), with lower perceived exertion at the end of the test (MD -1.2, 95% CI -1.9 to -0.4). The experimental group also improved more than the control group on several respiratory measures, including: FEV1 (MD 270 ml, 95% CI 30 to 510), maximal inspiratory pressure (MD 4 cmH2O, 95% CI 1 to 8) and peak expiratory flow (MD 33 l/minute, 95% CI 7 to 58). CONCLUSION: In adolescents with idiopathic scoliosis, combined aerobic and resistance training improves functional exercise capacity and several respiratory outcomes more than a similar training regimen with aerobic training only. It is unclear whether the magnitude of the benefits is large enough to be worthwhile. TRIAL REGISTRATION: NCT02413788.

ABSTRACT

ABSTRACT Objective: To evaluate the profile of patients with fracture and / or dislocation of the subaxial cervical spine using the new AOSpine classification and to correlate it with the trauma mechanism and the type of neurological deficit. Methods: Analyses were performed of the medical records of patients admitted to a tertiary hospital with fracture and / or subaxial cervical dislocation during the period from 2009 to 2016. For the evaluation of the association between the two categorical variables, the Chi-square test was used with a significance level of p <0.05. Results: A total of 67 medical records were analyzed, in which a higher prevalence of type C fractures (49.3%) was observed. The neurological subclassification N4 (35.8%) was the most prevalent type found, followed by subtype N0 (26.9%). Among the main injury mechanisms found, the most prevalent was the motorcycle accident (29.9%). There was no statistically significant association between the injury mechanism and the AOSpine morphological classification (p> 0.05) or neurological deficit (p> 0.05). Conclusion: Cervical fractures of type C, due to automobile accidents were the most prevalent. It was not possible to determine an association between the degree of neurological involvement and the morphology of the injury. Level of Evidence II; Retrospective study.


RESUMO Objetivo: Avaliar o perfil dos pacientes com fratura e/ou luxação da coluna cervical subaxial por meio da nova classificação AOSpine e correlacionar com o mecanismo de trauma e o tipo de déficit neurológico. Métodos: Foram realizadas análises dos prontuários médicos dos pacientes admitidos em um hospital terciário com fratura e/ou luxação cervical subaxial entre o período de 2009 a 2016. Para a avaliação da associação entre as duas variáveis categóricas, utilizou-se o teste Qui-quadrado com nível de significância de p<0,05. Resultados: Foram analisados 67 prontuários, em que se obteve maior prevalência para as fraturas do tipo C (49,3%). A subclassificação neurológica N4 (35,8%) foi o tipo mais prevalente encontrado, seguido pelo subtipo N0 (26,9%). Entre os principais mecanismos de lesão encontrados, o mais prevalente foi o acidente motociclístico (29,9%). Não foi observada associação estatisticamente significativa entre o mecanismo de lesão com a classificação morfológica AOSpine (p > 0,05) ou com o déficit neurológico (p > 0,05). Conclusão: As fraturas cervicais do tipo C, devido a acidentes automobilísticos, foram as mais prevalentes. Não foi possível obter associação entre o grau de acometimento neurológico e a morfologia da lesão. Nível de evidência II; Estudo Retrospectivo.

ABSTRACT

STUDY DESIGN: Systematic review. OBJECTIVES: To assess the efficacy of kyphoplasty in controlling pain and improving quality of life in oncologic patients with metastatic spinal disease and pathologic compression fractures of the spine. METHODS: A literature search through medical database was conducted (using PubMed, EMBASE, Cochrane, and LILACS) for randomized controlled trials comparing balloon kyphoplasty versus the traditional treatment for compression fractures of the spine due to metastatic disease. Two investigators independently assessed all titles and abstracts to select potential articles to be included. Inclusion criteria consisted of randomized controlled trials involving patients with pathologic compression fractures due to spinal metastasis or multiple myeloma treated with balloon kyphoplasty procedure as one of the study interventions, while the control group was any other treatment modality. The risk of bias in individual studies was assessed. RESULTS: Two studies, with a combined total of 181 patients, met inclusion criteria. Because of data heterogeneity, the meta-analysis was not possible, and individual analysis of studies was performed. There is moderate evidence that patients treated with balloon kyphoplasty displayed better scores for pain (Numeric Rating Scale), disability (Roland-Morris Disability Questionnaire), quality of life (Short Form-36 Health Survey), and functional status (Karnofsky Performance Status) compared with those undergoing the conventional treatment. Patients treated with kyphoplasty also have better recovery of vertebral height. CONCLUSIONS: This study concluded that balloon kyphoplasty could be considered as an early treatment option for patients with symptomatic neoplastic spinal disease, although further randomized clinical trials should be performed for improvement of the quality of evidence.

ABSTRACT

ABSTRACT Objective: The objective of this study is to compare short posterior fixation to long posterior fixation in thoracolumbar burst fractures. Methods: Fifty-three patients were divided into Group I (n=24) treated with short instrumentation (one level above and one below the fracture) and into Group II (n=29) treated with long instrumentation (two or more levels above and below the fracture). The load sharing classification was used to stratify cases. The evaluation of the sagittal index was performed using the Cobb method. Results: In subgroups with load sharing classification ≤ 6, Group I had loss of correction of 4.2 degrees and a procedure failure in 14.3% of cases, Group II showed loss of correction of 5.4 degrees and failure in 21.7% of cases. In subgroups with load sharing classification ≥7, Group I had a loss of correction of 11.2 degrees and procedure failure in 70% of cases, and Group II showed a loss of correction of 9 degrees and failure of 46.7%. Group I had a tendency to worse outcomes, especially in the subgroup of patients with load sharing classification ≥7. Conclusion: Despite the tendency for poorer results in the short fixation group in the cases with load sharing ≥7, in no sample was there statistically significant difference between the groups studied.


RESUMO Objetivo: O objetivo deste estudo é comparar fixação posterior curta e longa em fraturas toracolombares do tipo explosão. Métodos: Cinquenta e três pacientes foram divididos em Grupo I (n = 24), tratados com instrumentação curta (um nível acima e um abaixo da fratura) e Grupo II (n = 29), tratados com instrumentação longa (dois ou mais níveis acima e abaixo da fratura). A classificação Load Sharing foi utilizada para estratificar os casos. A avaliação do índice sagital foi realizada pelo método de Cobb. Resultados: Nos subgrupos com classificação Load Sharing ≤ 6, o Grupo I teve perda da correção de 4,2 graus e uma falha do procedimento em 14,3% dos casos, o Grupo II apresentou perda da correção de 5,4 graus e falha de procedimento em 21,7% dos casos. Nos subgrupos com classificação Load Sharing ≥ 7, o Grupo I teve perda da correção de 11,2 graus e falha do procedimento em 70% dos casos, o Grupo II apresentou perda da correção de 9 graus e falha de 46,7%. O Grupo I apresentou tendência a piores resultados, principalmente no subgrupo dos pacientes que apresentavam classificação Load Sharing ≥ 7. Conclusão: Apesar da tendência de piores resultados no grupo de fixação curta nos casos com Load Sharing ≥7, em nenhuma avaliação desta amostra houve diferença estatisticamente significante entre os grupos estudados.


RESUMEN Objetivo: El objetivo de este estudio es comparar la fijación posterior corta y larga en fracturas toracolumbares del tipo explosión.

ABSTRACT

ABSTRACT Objective: To analyze the impact of a physiotherapy protocol in maximum inspiratory and expiratory pressure in patients with adolescent idiopathic scoliosis (AIS) by manovacuometry. AIS may change the respiratory dynamics and the performance of inspiratory and expiratory muscles, affecting ventilatory capacity. Methods: Patients with AIS aged 10 to 20 years old were randomly assigned to receive an aerobic exercise-training program or no treatment. They were evaluated for respiratory muscle strength before and after the treatment period by means of manovacuometry, thorax and spine radiographs. Physical therapy exercising protocol comprised three weekly sessions including stretching and aerobic exercises during four months. Results: Forty five patients received physical therapy and 45 patients received no treatment (control group). The mean maximum inspiratory pressure (Pimax) was -52.13 cm H20 and the maximum expiratory pressure (Pemax) was 62.38 cm H20. There was a significant increase of Pimax and Pemax (p=0,000) in the group receiving physical therapy. There were no drop-outs and no adverse events in this study. Respiratory muscle strength, scoliosis and kyphosis degrees were not statistically correlated. Conclusion: Exercising is beneficial to patients with AIS, who have shown significant increases in respiratory muscle strength after physical therapy. There was no correlation between respiratory pressure and spine deformity. Level of Evidence I, High quality randomized trial.

ABSTRACT

ABSTRACT Objective: To evaluate clinical and functional results of patients with lumbar degenerative spondylolisthesis treated with operatively or nonoperatively. Methods: Patients with degenerative spondylolisthesis treated either nonoperatively or operatively from 2004 to 2014 were selected from databases and a cross-sectional evaluation was performed. Outcome measures included back and leg visual analogue scales (VAS), Fischgrund criteria, Short Form-36 (SF-36) function score, and the modified Oswestry Disability Index (ODI). Results: 43 patients were evaluated: 20 with nonoperative treatment and 23 with operative treatment. Baseline characteristics were similar without significant differences between groups. Mean follow-up time was 43 months (range 10 - 72) for the nonoperative group and 36 months (range 6-80) for the operative group. Significant statistical difference in favor of operative group were found in back VAS (mean 4 versus 8, p = 0.000), leg VAS (mean 3 versus 6, p = 0.0015), SF-36 function score (mean 77 versus 35, p = 0.000), and ODI (mean 17 versus 46, p = 0.000). On the basis of the Fischgrund criteria, only 10 % of patients reported excellent or good health post nonoperative treatment versus 83% for those treated operatively (p = 0.000). Conclusion: In this cross-sectional study, we observed that symptomatic patients with degenerative spondylolisthesis who underwent operative treatment have superior clinical and functional scores compared to those that underwent nonoperative treatment.

ABSTRACT

Objective : To evaluate and compare radiographic and clinical evaluation of patients undergoing interbody fusion versus posterolateral fusion of the lumbar spine. Methods : Retrospective study of patients diagnosed with lumbar spondylosis that were surgically treated in the period from 2012 to 2014. The results were observed by clinical evaluation by the Visual Analogue Scale (VAS) for low back and leg pain. We evaluated functional results and quality of life through the application of the Oswestry Disability Index (ODI) and the Short Form-36 (SF-36) questionnaires, respectively. The pre and postoperative condition were compared in Group 1 (interbody fusion) and Group 2 (posterolateral fusion), in addition to evaluation of fusion by means of post-operative radiograph. Results : A total of 30 patients of 36 were eligible, 12 in Group 1 and 18 in Group 2. The mean follow-up was 10.1 months. Statistical analysis showed similar scores for back and leg pain VAS, SF-36 function scores and Oswestry between groups with interbody and posterolateral fusion, and compared within these groups regarding the pre- and postoperative condition, and found no statistical significance. The successful fusion was similar in both groups, with 11 of 12 patients in Group 1 showing bone fusion and 17 of 18 in Group 2 showing arthrodesis. Conclusion : No clinical or radiographic differences between patients who underwent posterolateral or interbody fusion were observed. Both methods showed improvement in functional outcome and pain reduction.


Objetivo : Avaliar e comparar a evolução radiográfica e clínica dos pacientes submetidos à artrodese intersomática em comparação com a posterolateral na coluna lombar. Métodos : Estudo retrospectivo de pacientes com diagnóstico de espondilose lombar, submetidos ao tratamento cirúrgico no período de 2012 a 2014. Os resultados foram observados por avaliação clínica pela aplicação da Escala Visual Analógica (EVA) para dor com relação à dor lombar e nos membros inferiores. Foram avaliados resultados funcionais e de qualidade de vida através dos questionários Oswestry Disability Index (ODI) e o Short Form-36 (SF-36), respectivamente. A situação pré e pós-operatória foi comparada no Grupo 1 (artrodese intersomática) e no Grupo 2 (artrodese posterolateral), além da avaliação da fusão por meio de radiografia pós-operatória. Resultados : Foram avaliados 30 pacientes de 36 elegíveis, sendo 12 do Grupo 1 e 18 do Grupo 2. O seguimento médio dos pacientes foi de 10,1 meses. Os resultados da análise estatística mostraram pontuações semelhantes para EVA lombar, EVA na perna, função no SF-36 e Oswestry entre os grupos com artrodese intersomática e posterolateral, assim como na comparação dentro desses grupos referente ao estado pré e pós-operatório, sem significância estatística. A fusão bem-sucedida foi semelhante nos grupos, com 11 de 12 no Grupo 1 mostrando sucesso e 17 de 18 no Grupo 2 também evidenciando artrodese. Conclusão: Não foram observadas diferenças clínicas ou radiográficas entre pacientes submetidos à artrodese intersomática e posterolateral. Ambos os métodos apresentaram melhora no resultado funcional e na redução da dor.

Los resultados del análisis estadístico mostraron puntuaciones similares para EVA lumbar, EVA de las extremidades inferiores, SF-36 y Oswestry entre los grupos con artrodesis intersomática y artrodesis posterolateral, así como la comparación dentro de estos grupos en relación con el estado de pre y postoperatorio y sin significación estadística. La fusión fue similar en ambos grupos con 11 de 12 en el Grupo 1 que tuvieron éxito y 17 de 18 en el Grupo 2 que presentaron artrodesis. Conclusión : No se observaron diferencias clínicas o radiográficas entre los pacientes sometidos a artrodesis intersomática y posterolateral. Ambos métodos mostraron una mejoría en los resultados funcionales y la reducción del dolor.

ABSTRACT

OBJECTIVES: To compare the clinical outcomes between patients with degenerative lumbar stenosis who were treated by decompression with those awaiting the same kind of treatment for the disease. METHODS: Retrospective study which divided patients with degenerative lumbar stenosis with surgical indication in 2 groups, operated and awaiting the procedure. The Oswestry Disability Index (ODI) questionnaire, visual analog scale and SF36 were applied. RESULTS: Twelve operated patients and 18 awaiting the procedure were included. The average age of those operated was 59 years (43-70), and 55 (37-82) (p=0.3) for those awaiting surgery. The operated group had a mean ODI of 38.67 against 59.72 (p<0.05) in the non-operated group. The pain analog scale had lumbar result of 5.33 and pain radiating to the lower limbs of 3.83 in operated patients, against 6.78 (p>0.05) and 7.22 (p<0.05) in the awaiting surgery patients, respectively. As for the SF36 scale, functional capacity, limitations due to physical aspects and pain had an average score of 36.25, 19.58 and 21.67 in the operated group against 35.94, 27.50 and 32.61 in the awaiting group (p>0.05), respectively. CONCLUSION: The operated patients showed improvement of referred pain in the lower limbs (leg VAS) and improved function (Oswestry), however showed no significant change in quality of life according to SF36 scale and low back pain (lumbar VAS) were found.

ABSTRACT

Previous studies have shown that sonication fluid cultures from removed orthopedic devices improved the microbiological diagnosis of orthopedic implant-associated infections; however, few of these investigations have applied sonication to the removed fracture fixation devices to evaluate its utility for the diagnosis of osteosynthesis-associated infection (OAI). We compared sonication fluid to conventional tissue cultures from 180 subjects with different sizes of plates and screws (n = 156), spinal implants (n = 26), and intramedullary nails (n = 3), of whom 125 and 55 subjects had OAI and noninfected osteosynthesis (NIO), respectively. The sensitivity for detecting OAI was 90.4% for sonication fluid culture and 56.8% for periprosthetic tissue cultures (P < 0.05), and the specificities were 90.9% and 96.4%, respectively. Sonication fluid culture detected more pathogens than peri-implant tissue culture (113 versus 71; P < 0.001), while polymicrobial infections were diagnosed by sonication fluid cultures and tissue cultures in 20.8% and 8% (P < 0.001), respectively. Microbiological diagnosis was achieved exclusively by sonication fluid cultures for 47 (90.4%) subjects, and among them, 18 (38.3%) had previously received antibiotics, whereas in five (9.6%) infected subjects, tissue culture was positive and the sonication fluid culture was negative. Among 39 (31.2%) OAI cases receiving antibiotics, the identification of the organisms occurred in 38.5% and 82.1% of the tissue and sonication fluid cultures, respectively (P < 0.049). We demonstrated that sonication fluid culture from removed osteosyntheses has the potential for improving the microbiological diagnosis of OAI.

ABSTRACT

OBJECTIVE: To analyze the clinical and radiographic changes in patients with postural rounded upper back. METHODS: 30 patients diagnosed with postural rounded upper back were studied, being 22 male and eight female, aged between 10 and 20 years, referred by the outpatient clinic of the Grupo de Cirurgia da Coluna of the Irmandade da Santa Casa de Misericórdia de São Paulo, SP, Brazil. Patients underwent assessment of posture, special tests to check for muscle retractions and radiographic examination to measure the curvatures of spine using the Cobb method. RESULTS/CONCLUSION: It is concluded that in the postural roundback there is a moderate increase of the thoracic kyphosis; the lumbar and cervical curvatures do not increase as a compensatory mechanism; the head appears anteriorized and the shoulder is also anteriorized and medially rotated; muscle retractions are present in the hamstrings, hip flexors, pectoralis minor and adductors of the shoulder muscles; the mobility of the lumbar spine is preserved and there is no relationship between the magnitude of thoracic curvature and the retraction of the hamstring muscles. .

ABSTRACT

Patients with adolescent idiopathic scoliosis (AIS) have lower potential for physical activity because of lung dysfunction and lower muscle strength, which can be reversed by the cardiorespiratory and musculoskeletal conditioning provided by standardized physical activities. We conducted a study to determine if a preoperative protocol of aerobic exercise would improve quality of life (QoL) both before and after training and if there would be any differences between patients who received the therapy and those who did not. Patients with the indication of surgical correction of AIS were randomized to receive or not receive a 4-month preoperative course of aerobic physical training. At baseline and after 4 months, they were evaluated with the Short Form-36 questionnaire (SF-36). QoL scores improved for the study group but did not change for the control group. In all QoL domains, the study group's mean score increased significantly between baseline and 4 months. We concluded that the proposed preoperative physical therapy protocol improved the QoL of patients with AIS.

ABSTRACT

PURPOSE: Because the medial patellofemoral ligament (MPFL) is the primary restraint to lateral dislocation of the patella, we aimed, in this controlled study, to verify whether the MPFL with different measurements could be considered another predisposing factor for patellar dislocation. METHODS: A group of 100 consecutive individuals without the criteria for patellar dislocation (trochlear dysplasia, patella alta and lateral patellar tilt) was recruited as a control group and underwent magnetic resonance imaging (MRI) study and another group of 50 patients with patellar instability. Femoral condyles, interepicondylar distance, length and thickness of the MPFL were measured. RESULTS: In the control group, the MPFL was 38-60 mm long. Individuals with patellar instability who had no episode of patellar dislocation had a 4.11-mm longer ligament than controls (p = 0.032), while patients with instability with a previous history of dislocation had a 13.54-mm longer MPFL than controls (p < 0.001). Thickness of the MPFL at the patellar insertion was lower in individuals with patellar instability with a history of dislocation (p < 0.001). An instability coefficient (IC) less than 1.3 indicates that the MPFL is insufficient. CONCLUSIONS: Individuals with patellar instability and previous patellar dislocation present with longer MPFL when compared to controls, and an associated IC less than 1.3 can be considered a predisposing factor for patellar dislocation. Treatment of patellar instability is a challenge, and it is difficult to identify what is the predisposing factor. This study has verified the measurements of the MPFL for the first time and presents values of thickness and length that can be considered as indications for surgical reconstruction. LEVEL OF EVIDENCE: III.

ABSTRACT

OBJECTIVE: Perform radiographic analysis of the use of Transverse Traction Device (DTT) with respect to fusion rate in patients submitted to vertebral arthrodesis for degenerative lumbar diseases. METHODS: We selected x-ray images on anteroposterior, lateral and oblique views and with maximum flexion and extension dynamics of 23 patients submitted to posterolateral arthrodesis of the lumbar spine with a minimum follow-up period of six months. The images were evaluated and classified by the Linovitz's system by two spine surgeons. RESULTS: We evaluated the radiographs of 23 patients after the minimum postoperative period of 6 months and of these, 11 have used DTT. With regard to the consolidation rate, seven patients (63.6%) in the group of DTT were classified as fusion as well as six patients (50%) who were not submitted to the treatment. There was no statistical difference between the groups regarding the consolidation rate. CONCLUSION: The use of transverse traction device in this study showed no significant difference in the rate of consolidation in radiographic evaluation. Studies on the effective participation of this device in the stability of pedicle fixation systems are still lacking in the literature. .

MÉTODOS: Foram selecionadas radiografias nas incidências anteroposterior, perfil, oblíquas e dinâmicas em flexão e extensão máxima de 23 pacientes submetidos à artrodese posterolateral da coluna lombar com seguimento pós-operatório mínimo de seis meses. As imagens foram avaliadas e classificadas pelo sistema de Linovitz, por dois cirurgiões de coluna. RESULTADOS: Avaliamos as radiografias de 23 pacientes no pós-operatório mínimo de 6 meses sendo que destes, 11 fizeram uso do DTT. Quanto à taxa de consolidação foram classificados como fusão sete pacientes (63,6%) no grupo que recebeu o DTT e seis pacientes (50%) naqueles em que o dispositivo não foi utilizado. Não observamos diferença estatística entre os grupos quanto à taxa de consolidação. CONCLUSÃO: A utilização do dispositivo de tração transversa neste estudo não apresentou diferença significativa quanto à taxa de consolidação na avaliação radiográfica. Ainda faltam na literatura estudos sobre a efetiva participação deste dispositivo na estabilidade dos sistemas de fixação pedicular. .

ABSTRACT

OBJECTIVE: To examine the sagittal curves of patients treated with CD instrumentation using exclusively pedicle screws. METHODS: Image analysis of medical records of 27 patients (26 M and 1 F) with a minimum follow-up of 6 months, who underwent surgical treatment in our service between January 2005 and December 2010. The curves were evaluated on coronal and sagittal planes, taking into account the potential correction of the technique. RESULTS: In the coronal plan the following curves were evaluated: proximal thoracic (TPx), main thoracic (TPp), and thoracolumbar; lumbar (TL, L), and the average flexibility was 52%, 52%, and 92% and the capacity of correction was 51%, 72%, and 64%, respectively. In the sagittal plane there was a mean increase in thoracic kyphosis (CT) of 41% and an average reduction of lumbar lordosis (LL) of 17%. Correlation analysis between variables showed Pearson coefficient of correlation of 0.053 and analysis of dispersion of R2 = <0.001. CONCLUSION: The method has shown satisfactory results with maintenance of kyphosis correction in patients with normal and hyper kyphotic deformities. .

ABSTRACT

STUDY DESIGN: Prospective observational study. OBJECTIVE: To assess patient quality of life before and after surgical treatment of adolescent idiopathic scoliosis (AIS) and determine whether an association exists between quality of life and curve magnitude, curve correction, and type of instrumentation. SUMMARY OF BACKGROUND DATA: Assessment of AIS surgery outcomes has always been based on analysis of radiographic measurements and postoperative curve correction. However, there is a current trend toward greater emphasis on patient-centered outcomes. Assessment of treatment success on the basis of these outcomes requires prospective use of quality-of-life surveys before and after AIS treatment. METHODS: Prospective study of 33 patients undergoing surgical treatment of AIS. Mean age was 15.6 years and mean Cobb angle was 70.5 degrees. Patients were randomly allocated into one of 2 instrumentation groups (hybrid and pedicle screws alone), and the Scoliosis Research Society-30 questionnaire (SRS-30) and Short Form-36 Health Survey (SF-36) questionnaires were administered preoperatively and at 3-, 6-, and 12-month follow-up. Statistical testing was performed to determine whether survey scores correlated with Cobb angle, curve correction, or type of instrumentation. RESULTS: SRS-30 and SF-36 scores improved significantly. The greatest changes occurred in the self-image and satisfaction with management domains of the SRS-30 survey. SRS-30 and SF-36 scores showed worsening pain and decreased function at 3-month follow-up, but significant improvement from baseline at 12 months. Total SRS-30 scores were significantly improved at 6- and 12-month follow-up, as were subscores in the general health, vitality, and social functioning domains of SF-36. Curve magnitude, percent curve correction, and type of instrumentation had no significant influence on final SRS-30 and SF-36 scores. CONCLUSIONS: Surgical treatment of AIS improved patient quality of life, as shown by significant improvement on all SRS-30 and SF-36 domains. Questionnaire scores did not correlate with Cobb angle, curve correction, or type of instrumentation.

ABSTRACT

Objective: This study evaluates the manual and digital reliability and reproducibility of five methods of measuring deformity (kyphosis) in thoracolumbar burst fractures. Method: Ninety (90) tomographic images were evaluated and, in each case, kyphotic deformity was measured, both manually and digitally, through the five most relevant methods described in the literature. For the assessment of intraobserver error, 20 cases were measured again. Results: The results show that all five methods are highly reliable and digitally reproducible, with estimated error near or lower than that indicated in the intraobserver error analysis. Cobb's method had the highest concordance (96%) while the sagittal index had the lowest concordance (75%). It is also suggested that digital assessment is more reliable then the manual method. Conclusion: All tested methods are highly reliable and digitally reproducible.


Objetivo: Avaliar a confiabilidade e reprodutibilidade manual e digital dos cinco métodos de aferição da deformidade (cifose) na fratura toracolombar tipo explosão. Métodos: Foram avaliadas 90 imagens tomográficas e, em cada caso, foi medido o valor angular da deformidade em cifose, tanto de forma manual como de forma digital, através dos cinco métodos mais relevantes descritos na literatura atual. Foram novamente aferidos 20 exames para avaliação do erro intraexaminador. Resultados: Todos os cinco métodos são altamente confiáveis e reprodutíveis de forma digital, com erro estimado próximo ou menor que o apontado na análise do erro intraexaminador, sendo o método de Cobb o de maior concordância (96%) e o índice sagital, o de menor concordância (75%). Sugere-se também que a aferição digital tenha confiabilidade superior à aferição manual. Conclusão: Todos os métodos testados são altamente confiáveis e reprodutíveis na forma digital.

ABSTRACT

Objective: To demonstrate the safety of soccer for adolescents in terms of chronic lesions of the lumbar spine, particularly spondylolysis. Methods: 54 young players underwent a pre-season assessment. The athletes were submitted to radiography of the lumbosacral spine. Players complaining of chronic low back pain were later submitted to more specific tests. Results: only 1 athlete (1.85 % of our sample) had complaints of chronic low back pain. In this case, the radiograph showed olisthesis grade I spondylolysis at the L5 level. Conclusion: Soccer proved to be a very safe sport in terms of the risk of developing chronic lesions of the lumbosacral spine. However, the actual incidence of spondylolysis in these athletes was not determined because only plain radiographs were used in this study.


Objetivo: Demonstrar a segurança da prática do futebol para adolescentes em relação às lesões crônicas da coluna lombar, em especial a espondilólise. Métodos: Cinquenta e quatro jovens jogadores realizaram a avaliação da pré-temporada. Os atletas foram submetidos a radiografias da coluna lombossacra. Jogadores com queixa de lombalgia crônica seriam submetidos posteriormente a exames mais específicos. Resultados: Apenas um atleta tinha queixa de lombalgia crônica. Neste caso, a radiografia evidenciou espondilólise bilateral de L5 com listese grau I (1,85% de nossa casuística). Conclusão: O futebol de campo mostrou ser um esporte bastante seguro quanto ao risco de desenvolvimento de lesões crônicas da coluna lombossacra. No entanto a real incidência da espondilólise nesses atletas não foi determinada, porque apenas radiografias simples foram utilizadas neste estudo.
