RESUMO

Purpose: The aim of this study was to determine correlation between the spinopelvic parameters in sitting and standing positions (sacral slope [SS], lumbar lordosis [LL], spinopelvic tilt [SPT], pelvic incidence [PI], and pelvic femoral angle [PFA]), with hip function assessed using the modified Harris hip scores (mHHs) in patients with symptomatic femoroacetabular impingement (FAI) at diagnosis. Materials and Methods: A retrospective study of 52 patients diagnosed with symptomatic FAI was conducted. Evaluation of the spinopelvic complex in terms of SS, LL, SPT, PI and PFA was performed using lateral radiographs of the pelvis and lumbosacral spine in standing and sitting positions. Assessment of hip function at diagnosis was performed using the mHHs. Calculation of spinopelvic mobility was based on the difference (Δ) between measurements performed in standing and sitting position. Results: The median time of pain evolution was 11 months (interquartile range [IQR], 5-24 months) with a median mHHs of 66.0 points (IQR, 46.0-73.0) at diagnosis. The mean change of LL, SS, SPT, and PFA was 20.9±11.2°, 14.2±8.6°, 15.5±9.0°, and 70.7±9.5°, respectively. No statistically significant correlation was observed between spinopelvic parameters and the mHHs (P>0.05). Conclusion: Radiological parameters of the spinopelvic complex did not show correlation with hip function at the time of diagnosis in patients with symptomatic FAI. Conduct of further studies will be required in the effort to understand the effect of the spinopelvic complex and its compensatory mechanics, primarily between the hip and spine, in patients with FAI before and after hip arthroscopy.

RESUMO

Hypopressive exercises (HE) are part of the Low Pressure Fitness training program which is widely used by physical therapists in the rehabilitation of the pelvic floor, abdominal and spinal musculature. The aim of this study was to compare the effects of HE on the sagittal lumbo-pelvic posture in athletic and non-athletic females. It was hypothesized that a 5-week training program of HE could influence lumbo-pelvic position while reducing abdominal circumference and low back pain in athletic and non-athletic females. Twenty normoweight females (mean age = 24.8 (SD 3.5) years; body mass index = 22.4 (SD 1.6) kg/m2) participated in this study. Ten athletic females were rugby players (RG), and 10 females were non-athletic (SG). Participants completed twenty minutes of HE twice weekly for 5 weeks. Before and after the intervention, two-dimension photogrammetry was used to assess lumbar lordosis and pelvic horizontal alignment. A Visual Analog Scale was used to assess low back pain and cirtometry was used to assess abdominal circumferences at umbilical, supra and infra-umbilical levels. An analysis of variance between moments revealed no significant differences in lumbar lordosis and pelvic positioning but showed significant differences for abdominal circumferences between groups. No significant differences between groups were found for other variables. Significant correlations were found between the three different abdominal circumference measurements (p > 0.05) but not between lumbar lordosis and abdominal circumferences. These preliminary findings indicate that a 5-week HE intervention displayed non-significant changes in lumbar lordosis, pelvic horizontal alignment, and low back pain but a significant reduction in abdominal circumferences in non-athletic and athletic females.

RESUMO

Introducción Tenemos como objetivo, cuantificar los cambios de la lordosis fisiológica en las distintas posiciones, de pie y en decúbito ventral, sobre el Soporte de Cirugía Espinal (SCE) y evaluar indirectamente los cambios de diámetro de los distintos forámenes, midiendo la distancia interpedicular. Materiales y métodos 20 pacientes de 20 a 40 años. Se tomaron radiografías, en posición de pie y sobre el SCE. Se midió la lordosis lumbar en radiografías de pié, y sobre el SCE en dos posiciones (baja/alta) así como la distancia interpedicular de los forámenes de cada segmento. Resultados Se constata una pérdida de la lordosis en la primera posición de 21,65° (37,00%) y en la segunda posición de 28,75° (49,14%). Encontramos un aumento de la distancia interpedicular en todos los niveles tanto en la posición baja como alta del SCE. Los forámenes que presentaron mayor apertura fueron los segmentos de L4-L5, seguidos por L5-S1. Conclusiones Se encontró una pérdida promedio de la lordosis fisiológica del 37,00% y del 49,14% con la utilización del SCE en las dos posiciones utilizadas. En todos los casos existió un aumento de la distancia interpedicular, que vario entre un 10 y un 15%. Los forámenes que mayor apertura presentaron en las distintas posiciones fueron los segmentos L4-L5 seguido por L5-S1. La cifotización de los segmentos móviles permitirían una mejor liberación sacorradicular al aumentar el diámetro del canal y los forámenes. Nivel de Evidencia: IV

Background The aim of this study is to quantify the changes of the physiological lordosis in the different positions, standing and in ventral decubitus, on a Spinal Surgery Table (SST), and indirectly evaluate the changes in diameter of the different foramina, and measuring the interpedicular distance. Methods The study included 20 patients from 20 to 40 years old. X-rays were taken in standing position and on the SST. Lumbar lordosis was measured using the X-rays in the standing position, and on the SST in two positions (low/high), as well as the interpedicular distance of the foramina of each segment. Results A loss of lordosis was found in the first position of 22.65° (37.00%) and in the second position of 28.75° (49.14%). An increase was found in the interpedicular distance at all levels in both the low and high position of the SST. The foramina with the greatest opening were the L4-L5 segments, followed by L5-S1. Discussion A mean loss of 37.00% and 49.14%, respectively, was found in the physiological lordosis with the use the SST in the two positions used. In all cases there was an increase in the interpedicular distance, which varied between 10% and 15%. The foramina with the greatest openness in the different positions were segments L4-L5 followed by L5-S1. The kyphotisation of the mobile segments would allow a better sacrum-radicular release when increasing the diameter of the channel and the foramina. Evidence Level: IV

RESUMO

ABSTRACT Objective: Evaluate the discal height and lumbar lordosis gains, comparatively, according to the two lumbar arthrodesis techniques, transforaminal lumbar interbody fusion (TLIF) and posterior lumbar interbody fusion (PLIF), used in the treatment of spinal degenerative diseases. Methods: The present study, retrospective, was done with 60 patients who underwent decompression and 1 level lumbar arthrodesis in the Hospital Santa Casa de Misericórdia de Vitória (HSCMV), between January 2010 and December 2015. The patients were divided in two groups of 30 each, according to the utilized intersomatic arthrodesis technique: TLIF or PLIF. All patients presented pathologies at the L4-L5 level. In this study, the discal height gain and lumbar lordosis variation were evaluated by analyzing spinal radiographies of the pre and post-operatory periods from patients of the two groups, measured by the software Surgimap®. In addition, the pain intensity in the post-operatory period was estimated by the Visual Analog Scale for Pain (VAS Pain). Results: Both techniques presented a gain in the discal height in the post-operatory. There was no statistically significant difference between the discal height variation obtained with the PLIF technique when compared to the TLIF technique (p = 0.139). In the same way, there was no statistically significant difference in the lumbar lordosis variation between the two studied groups (p = 0.184). By the EVA Pain analysis, there was no significant difference in the pain intensity in the post-operatory period between both arthrodesis surgeries. Conclusion: There is no difference in the discal height gain and lumbar lordosis variation, as well as in the pain intensity in the post-operatory periods, in patients who underwent 1 level intersomatic arthrodesis when comparing the PLIF and TLIF techniques.

RESUMO

Objetivo: Evaluar las variables del plano sagital en pacientes con escoliosis idiopática del adolescente tratados mediante una artrodesis vertebral posterior instrumentada con tornillos pediculares y establecer relaciones entre ellas. Materiales y Métodos: Se evaluó retrospectivamente a 20 pacientes. Se compararon los cambios en la lordosis cervical, la cifosis torácica, la lordosis lumbar, la incidencia pelviana, el balance sagital global y la cifosis de la unión proximal en los espinogramas preoperatorio, posoperatorio inmediato y a los dos años de la cirugía. Se correlacionaron los cambios en la lordosis lumbar con la cifosis torácica y la incidencia pelviana. Resultados: Se observó una disminución significativa en la cifosis torácica y en la lordosis lumbar en el espinograma posoperatorio inmediato. Ambos parámetros mostraron un aumento en el espinograma a los dos años. Se halló un aumento significativo en la cifosis de la unión proximal y en la lordosis cervical entre el preoperatorio y el posoperatorio a los dos años. La única correlación posoperatoria significativa fue entre la lordosis lumbar y la incidencia pelviana en el espinograma a los dos años de la cirugía. Conclusiones: La artrodesis vertebral posterior instrumentada con tornillos pediculares en curvas Lenke 1 provoca una reducción posoperatoria de la cifosis torácica y de la lordosis lumbar, y un aumento posoperatorio de la lordosis cervical y de la cifosis de la unión proximal. A los dos años, se observó un aumento de la lordosis lumbar no instrumentada, y que dicha lordosis lumbar se correlaciona significativamente con la incidencia pelviana.

Objective: To evaluate the sagittal profile variables in patients with adolescent idiopathic scoliosis who underwent selective thoracic posterior spinal instrumentation and fusion with pedicle screws and to determine relationships among them. Methods: Twenty consecutive patients were retrospectively evaluated. Changes in cervical lordosis, thoracic kyphosis, proximal junctional kyphosis, lumbar lordosis, pelvic incidence and global sagittal balance were compared in standing lateral radiographs performed before surgery, at the immediate postoperative period, and two years after surgery. Changes in postoperative lumbar lordosis were correlated with changes in thoracic kyphosis and pelvic incidence. Results: There was a significant decrease in thoracic kyphosis and lumbar lordosis between preoperative and immediate postoperative radiographs, but both parameters showed an increase in the radiographs two years later. A significant increase in proximal junctional kyphosis and cervical lordosis was also found between preoperative and 2-year postoperative radiographs. The only significant postoperative correlation found was between lumbar lordosis and pelvic incidence at 2-year follow-up control. Conclusions: Posterior spinal instrumentation and fusion with pedicle screws in Lenke type 1 deformities reduces thoracic kyphosis and lumbar lordosis, and increases cervical lordosis and proximal junctional kyphosis. Uninstrumented lumbar lordosis increased at 2-year follow-up and it is strongly related to the pelvic incidence.

RESUMO

Diversas técnicas foram, e estão sendo, desenvolvidas para a identificação e adequação de possíveis problemas no sistema esquelético dos indivíduos. Esta revisão tem por finalidade descrever os principais métodos de diagnóstico postural da coluna lombar. Diversos descritores relacionados ao tema foram utilizados nas bases de dados ISI Web of knowledgeSM, SCOPUS, SciELO e Pubmed. Os resultados apresentam as vantagens de limitações dos métodos: Radiografia, Técnica de avaliação postural por imagem ou fotometria, Técnica quadro de referência postural (PRF), Goniometria, Plataforma de Força, Ultrassonografia, Spinal Mouse, Ressonância magnética, Cinemática e Eletromiografia (EMG). Pode-se verificar que as técnicas de maior facilidade são a Fotometria, a Técnica quadro de referência postural (PRF), Plataforma de força e Goniometria. Por outro lado, apesar de serem pouco aplicáveis, a(s) técnica(s): Radiografia, Spinal Mouse, Ressonância magnética, Cinemática, Eletromiografia (EMG) e o Ultrassom são as que apresentam maior precisão na medida da curvatura lombar.

Several techniques have been and are being developed for the identification and adequacy of potential problems in the skeletal system of individuals. This review aims at describing the main methods for posture diagnosis of the lumbar spine. Several descriptors related to the topic were used in databases ISI Web of KnowledgeSM, SCOPUS, SciELO, and Pubmed. We presented the benefits of limitations of methods: Radiography, Postural Assessment Technique by imaging or photometry, Postural Reference Frame Technique (PRF), Goniometry, Power Platform, ultrasound, Spinal Mouse, Magnetic Resonance Imaging, Kinematics, Electromyography (EMG). The easiest techniques were: photometry, postural reference frame technique (PRF), Power Platform and Goniometry. On the other hand, though rarely applied, Radiography, Spinal Mouse, Magnetic Resonance Imaging, Kinematics, Electromyography (EMG) and ultrasound were those with greater accuracy in measuring lumbar curvature.

RESUMO

Introducción: El escrutinio de la postura lordótica lumbar (PLL) no es práctico en grandes poblaciones por la dificultad técnica del estándar de oro. Objetivo. Comparar la utilidad de un marco de referencia postural (MRP) vs. el ángulo de Ferguson para el diagnóstico de PLL. Material y métodos: Evaluación de una prueba diagnóstica. Se evaluó la presencia de PLL con un marco de referencia postural (MRP) (marco de madera utilizando hilos como referencia para medir la distancia entre curvatura lumbar y los glúteos) en 110 jóvenes asintomáticos. El estándar de oro fue la evaluación radiológica del ángulo de Ferguson. Se determinó la especificidad, sensibilidad, valor predictivo positivo (VPP) y valor predictivo negativo (VPN) del MRP. Resultados: Se estudiaron 110 sujetos (58 mujeres, 52 hombres). Sus edades fueron 18.8 ± 3 años, peso 63 ± 12 kg, talla 164 ± 8 cm e índice de masa corporal (IMC) 23.2 ± 4 kg/m2. Con un punto de corte ≥ 7 cm, la especificidad de la prueba fue de 94%, la sensibilidad de 17%, VPP de 50% y VPN de 75%. Conclusión: La prueba tuvo una alta especificidad y es útil en el estudio de PLL en jóvenes asintomáticos.

INTRODUCTION: Studying lumbar lordosis (LL) in large patient populations is not a practical approach due to the technical limitations of the gold standard. OBJECTIVE: Determine the specificity of a postural reference frame (PRF) in the diagnosis of LL. METHODS: A PRF (wooden frame using strings as a reference for measuring the distance between lumbar curvature and the glutei) was used as a diagnostic test to asses LL. The Ferguson angle, a radiologic evaluation, was used as gold standard. Specificity, sensitivity, positive predictive value (PPV), and negative predictive value (NPV) of the PRF were determined. RESULTS: One hundred and ten subjects were studied (58 women, 52 men). Mean age was 18.8 +/- 3 years, weight 63 +/- 12 kg, height 164 +/- 8 cm and body mass index (BMI) 23.2 +/- 4 kg/m2. With a cut-off point 37 cm, test specificity was 94%, sensitiivity was 17%, PPV was 50%, and NPV was 75%. CONCLUSION: The postural reference frame as an assessment tool is highly specific and can aid in the diagnosis of LL among young asymptomatic patients.
