ABSTRACT Introduction: The assessment of biomechanical changes related to the lower limbs is necessary in clinical practice to measure the potential risks of injury and the influences on existing dysfunction. Biomechanical changes related to previous ankle injuries are known to influence the performance of the entire lower limb. Objective: The aim of this study was to correlate muscle strength tests, performance tests and ankle stability with the Single Hop Test (SHT). Methods: 82 amateur runners were evaluated with isokinetic tests of quadriceps and hamstring muscle strength, as well as Y Balance Test (YBT), Weight-bearing Lung Test (WBLT), and the SHT. Results: The results showed there was a significant correlation between the SHT and the YBT in subjects with hamstring/quadriceps ratio (I/Q ratio) <0.55, and the length of the unilateral SHT with the peak torque of ipsilateral knee extensors. Conclusion: The study was successful in correlating the functional tests in question with the results obtained in isokinetic dynamometry. Level of Evidence V; Cross-Sectional Study.

Relação entre o índice de resistência vascular e o sucesso hemodinâmico de revascularizações distais dos membros inferiores / Vascular resistance index and the immediate hemodynamic success of lower limb distal artery revascularization

Resumo Contexto A cirurgia de revascularização é proposta para restaurar o fluxo sanguíneo para o pé nos casos de isquemia crítica (IC) devido a doença arterial obstrutiva periférica dos membros inferiores (MMII). O uso de ultrassonografia com Doppler (USD) vem despontando nos últimos anos como um método de grande valor para o planejamento cirúrgico dessa intervenção. Objetivos Avaliar a relação entre o índice de resistência (IR), mensurado por meio de USD, e o sucesso hemodinâmico imediato da cirurgia de revascularização dos MMII em pacientes com IC. Métodos O tipo de estudo empregado foi a coorte prospectiva, na qual foram avaliados 46 pacientes portadores de IC dos MMII submetidos à operação de revascularização infrainguinal por angioplastia ou em ponte de agosto de 2019 a fevereiro de 2022. Todos os pacientes foram submetidos à avaliação clínica vascular, à USD com medida do IR das artérias distais dos MMII, à arteriografia dos MMII e à aferição do índice tornozelo-braquial (ITB) no período pré-operatório. No pós-operatório imediato, todos os pacientes foram submetidos à nova aferição do ITB. Resultados Entre os 46 pacientes avaliados, 25 (54,3%) eram do sexo masculino. A idade variou de 32 a 89 anos (média de 67,83). Quanto ao sucesso hemodinâmico, avaliado pela comparação do ITB pré e pós-operatório, constatou-se que 31 (67,4%) pacientes apresentaram sucesso hemodinâmico após cirurgia de revascularização (aumento do ITB em 0,15 ou mais). Foi observada correlação positiva (p ≤ 0,05) entre o IR da artéria distal revascularizada do MMII e o sucesso hemodinâmico imediato avaliado pela aferição do ITB (IR menor e sucesso hemodinâmico). Conclusões Na presente pesquisa foi observada uma correlação positiva entre o índice de resistência arterial distal e o sucesso hemodinâmico nas revascularizações dos membros inferiores, avaliada através do índice tornozelobraquial, de forma que, quanto menor foi o IR, maior o sucesso hemodinâmico obtido.

Abstract Background Revascularization surgery is used to attempt to restore blood flow to the foot in patients with critical ischemia (CI) caused by peripheral arterial occlusive disease of the lower limbs (LL). Ultrasonography with Doppler (USD) SAH emerged in recent years as a highly valuable method for planning this surgical intervention. Objectives To evaluate the relationship between the resistance index (RI), measured with USD, and immediate hemodynamic success of LL revascularization surgery in patients with CI. Methods The study design was a prospective cohort assessing 46 patients with LL CLI who underwent operations to perform infrainguinal revascularization by angioplasty or bypass from August 2019 to February 2022. All patients underwent preoperative clinical vascular assessment with USD including measurement of the RI of distal LL arteries, LL arteriography, and measurement of the ankle-brachial index (ABI). All patients had their ABI measured again in the immediate postoperative period. Results Forty-six patients were assessed, 25 (54.3%) of whom were male. Age varied from 32 to 89 years (mean: 67.83). Hemodynamic success was assessed by comparison of preoperative and postoperative ABI, showing that hemodynamic success was achieved in 31 (67.4%) patients after revascularization surgery (ABI increased by 0.15 or more). A positive correlation (p ≤ 0.05) was observed between the RI of the distal revascularized LL artery and immediate hemodynamic success assessed by ABI (lower RI and hemodynamic success). Conclusions This study observed a positive correlation between the resistance index of the distal artery and immediate hemodynamic success of lower limb revascularizations, as assessed by the ankle-brachial index, so that the lower the RI the greater the hemodynamic success achieved.

Deformidad en equino del tobillo en edades pediátricas

La deformidad en equino del tobillo ocurre como consecuencia de múltiples entidades. Aunque la primera línea de tratamiento es la conservadora, las modalidades quirúrgicas son necesarias en la mayoría de los enfermos pediátricos. Estas últimas son las más empleadas por zonas del complejo músculo-tendinoso, en especial los alargamientos fraccionados y en forma de Z-plastia. El objetivo de este trabajo es actualizar y brindar información sobre los distintos procedimientos quirúrgicos en la corrección de la deformidad en equino del tobillo. En la búsqueda y análisis de la información se emplearon las siguientes palabras: equinus deformity, equino varus, equino valgus; drop foot deformity y Achilles tendon Z-lengthening. A partir de la información obtenida, se realizó unala revisión bibliográfica de un total de 187 artículos publicados en las bases de datos PubMed, Hinari, SciELO, EBSCO, Scopus, Medscape y Medline, mediante el gestor de búsqueda y administrador de referencias EndNote. De ellos se utilizaron 30, 28 de los últimos cinco años. Se hace referencia a la anatomía esencial de la zona, al igual que a la prueba de Silfverskiöld. Con relación a la imagenología, se describe la técnica para calcular la distancia del tendón a alargar. Se mencionan las técnicas quirúrgicas de alargamiento fraccionado, por Z-plastia, trasposición anterior del tendón de Aquiles y la hemiepifisiodesis.

Equinus deformity of the ankle occurs as a consequence of multiple entities. Although the first line of treatment is conservative, surgical modalities are necessary in most pediatric patients. The latter are the most used for areas of the muscle-tendinous complex, especially fractional and Z-plasty-shaped lengthening. The aim of this work is to update and provide information on the different surgical procedures in the correction of equinus deformity of the ankle. In the search and analysis of the information, the following words were used: equinus deformity, equinovarus, equinovalgus; drop foot deformity and Achilles tendon Z-lengthening. Based on the information obtained, a bibliographic review of a total of 187 articles published in PubMed, Hinari, SciELO, EBSCO, Scopus, Medscape and Medline databases was carried out using the search manager and reference administrator EndNote. Of these, 30 were used, 28 of the last five years. Reference is made to the essential anatomy of the area, as well as to the Silfverskiöld test. In relation to imaging, the technique to calculate the distance of the tendon to be lengthened is described. Fractional lengthening surgical techniques are mentioned, by Z-plasty, anterior transposition of the Achilles tendon and hemiepiphysiodesis.

Assessing the effect of prophylactic ankle taping on ankle and knee biomechanics during landing tasks in healthy individuals: A cross-sectional observational study

ABSTRACT BACKGROUND: Current research supports the fact that prophylactic ankle taping (AT) is effective in preventing ankle injuries in amateur and elite sports athletes. OBJECTIVE: This study aimed to investigate the effect of AT on balance, knee valgus during drop jump and single-leg countermovement jump (SL-CMJ) landings, and ankle range of motion (ROM) restriction in healthy participants. DESIGN AND SETTING: A cross-sectional observational study was conducted at the Universidad Europea de Madrid, Madrid, Spain. METHODS: Participants: Thirty-nine healthy individuals participated in this study and performed the movements under two conditions (with and without tape). Outcome measurements: ankle ROM, balance, SL-CMJ height, flight time, ground time, and knee valgus. Before any intervention, a random process was developed with a 1:1 allocation ratio, and the participants were assigned to groups A (tape-no tape) and B (no tape-tape). RESULTS: Significant differences between tape and no-tape moments were observed for drop jump knee valgus flexion (P = 0.007), with an increase in knee valgus in participants with ankle taping. Similarly, the Y-balance testshowed a significant decrease in all variables (P = 0.001 and), ankle dorsiflexion (P = 0.001) in participants with ankle taping. CONCLUSIONS: AT is effective for immediate ankle ROM restriction. However, an increase in knee valgus during drop jump task and a decrease in lower limb balance were observed during drop jump task. Based on these results, it can be concluded that AT application in healthy individuals should not be recommended as it results in increase in injury risk factors.

Is ankle taping effective to limit the ankle dorsiflexion in a single-training session? An observational study in semi-professional basketball players

ABSTRACT BACKGROUND: Ankle taping (AT) is effective in preventing ankle sprain injuries in most common sports and is employed in rehabilitation and prevention sports. OBJECTIVE: This study aimed to investigate the effectiveness of AT to restricting excessive frontal plane ankle movements in semi-professional basketball players throughout the training session. DESIGN AND SETTING: A cross-sectional study was performed at the Universidad Europea de Madrid. METHODS: Forty male and female semi-professional basketball players were divided into two groups. The ankle dorsiflexion range of motion (ROM) and interlimb asymmetries in a weight-bearing lunge position were evaluated at four time points: 1) with no tape, 2) before practice, at 30 min of practice, and 3) immediately after practice. RESULTS: In male basketball players, no differences were observed in the right and left ankles between the baseline and 30 min and between baseline and 90 min of assessment. In female athletes, significant differences were reported between baseline and pre-training assessments for the right ankle and also significant differences between baseline and 90 min in both ankles. CONCLUSIONS: Ankle taping effectively decreased the ankle dorsiflexion ROM in male and female basketball players immediately after application. However, ROM restriction was very low after 30 and 90 min, as assessed in a single basketball practice. Therefore, the classic taping method should be revised to develop new prophylactic approaches, such as the implementation of semi-rigid bracing techniques or the addition of active stripes during training or game pauses.

Distal tibiofibular syndesmosis fibular notch typing and its clinical significance based on CT / 解剖学报

Objective To investigate the morphological typing and clinical significance of the distal tibiofibular syndesmosis fibular notch based on CT images. Methods According to the inclusion and exclusion ceiteria‚ the imaging data of patients undergoing ankle joint CT examination were analyzed‚ and the inferior tibiofibular joint fibula notch was classified according to the morphological characteristics. The measurements included 8 distances. There were 123 males and 102 females‚ all of whom were Han nationality‚ aged 18-60 years old. Results Retrospectively analyzed the result of 225 patients from December 2013 to December 2022. The distal tibiofibular syndesmosis fibular notch was divided into four types according to morphological characteristics‚ C-shaped (50. 67%)‚ V-shaped (26. 67%)‚ flat-shaped (15. 11%) and L-shaped (7. 56%). The angle between the anterior and posterior facets of the flat shape (145. 56 ± 9. 25)° was the largest and the angle between the anterior and posterior facets of the L shape (125. 07 ± 13. 54)° was the smallest(P< 0. 05); the depth of the notch in the flat shape (3. 11 ± 0. 83) mm was the smallest and in the L shape (4. 47±1. 11) mm was the largest(P<0. 05);The posterior facet length (13. 06 ± 3. 56) mm and anterior tibiofibular gap (3. 83±1. 49) mm on left were larger than on the right side (P<0. 05); The posterior facet length (13. 36 ± 3. 46) mm‚ fibular notch depth (3. 93 ± 1. 10) mm and vertical distance of tibiofibular overlap (9. 10 ± 2. 55) mm larger in men than in women (P<0. 05). Conclusion In this study‚ the data related to the inferior tibiofibular syndesmosis notch were measured and divided into four types according to the shape. The flat inferior tibiofibular syndesmosis notch is more likely to have chronic ankle instability‚ and the fibula is more likely to move forward during anatomical reduction. The inferior tibiofibular syndesmosis of L-shaped and C-shaped notches is more prone to posterior displacement of fibula or poor rotation reduction during anatomical reduction.

Relationship of balance in static single-leg stance to muscle strength and position sense of ankle in individuals with functional ankle instability / 中国康复理论与实践

ObjectiveTo analyze the relationship of the static single-leg stance balance with ankle muscles strength and position sense in individuals with functional ankle instability (FAI). MethodsFrom March to May, 2023, 44 FAI individuals were recruited in Hebei Normal University, and the maximum isokinetic muscle strength (60°/s and 180°/s) and position sense as ankle flexion, extension, inversion and eversion were measured using isokinetic dynamometer; while the center of pressure (COP) sway distance and envelope area were measured as static single-leg stance with eyes open or closed using three-dimensional force plate. ResultsThe maximum isokinetic torque as ankle eversion at 180°/s correlated with the COP anterior-posterior sway distance with eyes closed (r = -0.378, P < 0.05). ConclusionExplosive ankle eversion strength is related with the balance in static single-leg stance, which may help to evaluate and intervent the ankle function of FAI individuals.

Profile of Ankle Isokinetic Strength and Proprioception in Elite Female Handball Players / Perfil de Fuerza Isokinética del Tobillo y Propiocepción en Jugadoras de Balonmano de Élite

SUMMARY: The evaluation of the invertor and evertor muscle strength and proprioception are important in terms of determining the risk of injury in handball players. The aim of this study was to determine the isokinetic strength and proprioception profile of the ankle invertor and evertor muscles of elite female handball players. Fifteen elite female handball players were included. Ankle invertor and evertor muscle strength and proprioception were evaluated using the isokinetic system. The isokinetic strength test was performed in concentric mode at 30°/s (5 repetitions) and 120°/s (10 repetitions). Proprioception sense was evaluated as active joint position sense. There was no statistically significant difference between the dominant and nondominant sides in terms of invertor and evertor muscle strength, evertor/invertor (Ever/Inver) ratio, and active joint position sense at both angular speeds (p>0.05). The Ever/Inver ratio on both sides was lower than normal values. It was concluded that the female handball players showed bilateral symmetry in the invertor and evertor muscles. However, the fact that the Ever/Inver strength ratio was lower than normal values on both sides suggested that caution should be exercised in terms of risks such as ankle sprain or chronic ankle instability. Pre-season evaluations should be made and it would be beneficial to add strengthening exercises to related muscle groups in training programs to normalize the unilateral ratios in these athletes.

La evaluación de la fuerza muscular inversora y eversora y la propiocepción son importantes para determinar el riesgo de lesión en los jugadores de balonmano. El objetivo de este estudio fue determinar la fuerza isocinética y el perfil de propiocepción de los músculos inversores y eversores del tobillo de jugadoras de balonmano de élite. Se incluyeron 15 jugadoras de élite de balonmano. La fuerza muscular inversora y eversora del tobillo y la propiocepción se evaluaron mediante el sistema isocinético. El test de fuerza isocinética se realizó en modo concéntrico a 30º/s (5 repeticiones) y 120º/s (10 repeticiones). El sentido de propiocepción se evaluó como sentido activo de posición articular. No hubo diferencias estadísticamente significativas entre los lados dominante y no dominante en términos de fuerza muscular inversora y eversora, relación eversor/inversor (Ever/ Inver) y sentido activo de la posición de la articulación en ambas velocidades angulares (p>0.05). La relación Ever/Inver en ambos lados fue inferior a los valores normales. Se concluyó que las jugadoras de balonmano presentaron simetría bilateral en los músculos inversores y eversores. Sin embargo, el hecho de que la relación de fuerza Ever/Inver fuera inferior a los valores normales en ambos lados sugirió que se debe tener precaución en términos de riesgos como el esguince de tobillo o la inestabilidad crónica de tobillo. Se deben realizar evaluaciones de pretemporada y sería beneficioso agregar ejercicios de fortalecimiento a los grupos musculares relacionados en los programas de entrenamiento para normalizar las proporciones unilaterales en estas atletas.

Fractura triplanar de tibia distal: Reporte de un caso y revisión de la literatura / Triplanar fracture of proximal tibia: A case report and literature review

Las fracturas triplanares de tibia distal, son fracturas complejas caracterizadas por afectación multiplanar, clasificándose como Salter Harris tipo IV, en el periodo de cierre fisiario. Son poco frecuentes, representando el 5-15% de las fracturas pediátricas. El mecanismo de lesión que ocurre con mayor frecuencia, consiste en supinación y rotación externa. La tomografía computarizada es actualmente el Gold Standard para el diagnóstico de este tipo de fractura, nos permite evaluar todos los planos, siendo la radiografía simple insuficiente para el diagnóstico ya que puede pasar desapercibida. Paciente de 14 años de edad con fractura triplanar en 2 partes de tibia distal, con resolución quirúrgica. Nuestro caso es un ejemplo de una fractura triplanar de tibia distal, la cual es de baja frecuencia, difícil diagnostico e interpretación. Presentamos imágenes preoperatorias, intraoperatorias y postoperatorias del manejo de esta lesión, obteniendo resultados satisfactorios clínicos, funcionales y en estudios de imágenes. Es indispensable lograr una reducción anatómica de la superficie articular para lograr una evolución satisfactoria. Se recomienda una tomografía computarizada para diagnosticar y manejar esta lesión de manera adecuada. El seguimiento postoperatorio es crucial para el manejo de este paciente, ya que se espera una discrepancia en la longitud de las extremidades y/o deformidad(AU)

Triplane fractures of the distal tibia are complex fractures characterized by multiplane effects. They are classified in the Salter-Harris system as type IV in the period of physeal closure. These fractures are rare and represent 5-15% of pediatric fractures. The most common mechanism of injury is supination and external rotation. Computed tomography is currently the Gold Standard for the diagnosis of this type of fracture since it allows us to evaluate all planes, while plain radiography is insufficient because the fracture can go unnoticed. The objective is to report the clinical case of a 14-year-old patient with triplanar fracture in 2 parts of the distal tibia with surgical resolution. This case is an example of a triplanar fracture of the distal tibia, which is of low frequency, and difficult to diagnose and interpret. Preoperative, intraoperative and postoperative images of the management of this lesion are presented, obtaining satisfactory clinical, functional and imaging study results. It is essential to achieve an anatomical reduction of the joint surface to achieve a satisfactory evolution. A CT scan is recommended to properly diagnose and manage this injury. Postoperative follow-up is crucial for the management of this patient, as a limb length discrepancy and/or deformity is expected(AU)

Complejo ligamentoso lateral de la articulación talocrural (tobillo): biometría y patrones de división / Lateral ankle ligamentous complex: biometrics and division patterns

El complejo ligamentoso lateral de la articulación talocrural o «tobillo» (CLT) contempla básicamente tres estructuras denominadas como ligamento talofibular anterior (LTFA), ligamento calcaneofibular (LCF) y ligamento talofibular posterior (LTFP). En los últimos artículos publicados en relación con la morfología del CLT, se clasifica al LTFA en tres tipos, basada en el número de bandas o fascículos. Esta variabilidad morfológica plantea nuevos desafíos de estudios anatómicos en la biomecánica y estabilidad de la región talocrural. El objetivo de este estudio fue profundizar la anatomía de este complejo, en base a disecciones por capa que nos permitan visualizar las relaciones existentes entre estos ligamentos y estructuras aledañas. Se utilizaron 10 piezas congeladas pertenecientes al Departamento de Anatomía y Medicina Legal de la Facultad de Medicina de la Universidad de Chile, cuyos ligamentos fueron localizados y medidos en ancho y longitud. Para el LTFA se observó un patrón único en 5 muestras, bifurcado en 4, mientras que en un caso se visualizó un patrón trifurcado. El conocimiento del complejo ligamentoso lateral de tobillo, así como de su dirección, biometría y bandas o fascículos son un importante aporte para la imagenología, rehabilitación, clínica y cirugías que aborden esta región.

SUMMARY: The lateral ankle complex (LAC) basically includes three structures called anterior talofibular ligament (ATFL), calcaneofibular ligament (CFL) and posterior talofibular ligament (PTFL). In recent works published in relation to the morphology of LAC, ATFL is classified into three types, based on the number of bands or fascicles. This morphological modification poses new challenges for anatomical studies in biomechanics and ankle stability. The objective of this is to deepen in greater detail the anatomy of this complex, based on dissections by layer that allow us to study the existing relationships between these ligaments and surrounding structures. 10 frozen pieces belonging to the Department of Anatomy and Legal Medicine of the Faculty of Medicine of the University of Chile were used; whose ligaments were located and measured in width and length. For ATFL, a single pattern was found in 5 samples, bifurcated in 4, while a trifurcated pattern was seen in one case. Knowledge of the lateral ligamentous complex of the ankle, as well as its direction, biometry and bands or fascicles, are an important contribution to imaging, rehabilitation, clinics and surgeries that address this region.

Flexible flatfoot in the childhood: negative influence of inappropriate footwear

An analysis was carried out in relation to the adverse effects produced by the use of inadequately made footwear in patients with flexible flat feet in pediatric ages; we carried out an anatomical-functional reminder of the foot as a basic structure for standing and walking. The functional adaptability of the feet was valued in those populations with the habit of walking barefoot, also making a description of the basic characteristics that a properly made footwear must have. We address the different therapeutic approaches and their behavior over time. We highlight the widespread use in our society of inappropriate footwear, mainly of the flip-flop type, and its negative influence on the feet of those children with flexible flat feet and valgus of the ankle.

Se llevó a cabo un análisis en relación a los efectos adversos producidos por el uso de calzados de confección inadecuada en los pacientes portadores de pies planos flexibles en edades pediátricas. Se realizó un recordatorio anatomo-funcional del pie como estructura básica para la bipedestación y la marcha. Se valoró la adaptabilidad funcional de los pies en aquellas poblaciones con hábito de andar descalzos, haciéndose, además, una descripción de las características básica que debe reunir un calzado adecuadamente confeccionado. Se abordó los diferentes enfoques terapéuticos y su comportamiento en el tiempo, destacando el uso generalizado en la sociedad cubana de calzados inapropiados, principalmente del tipo chancletas, y su influencia negativa sobre los pies de aquellos niños con pies planos flexibles y tobillo valgo.

Precisión y fiabilidad de la medición del índice tobillo-brazo utilizando un dispositivo oscilométrico versus el método Doppler / Accuracy and reliability of ankle-brachial index measurement using an oscillometric device versus the Doppler method

Introducción: la medición del índice tobillo-brazo (ITB) es una prueba de primera línea y con alta precisión diagnóstica para detectar la enfermedad vascular periférica (EVP). El método Doppler, considerado el estándar de oro, requiere del dispositivo y de un operador capacitado, lo que limita su uso en la atención primaria. Como alternativa, un método oscilométrico que emplea un dispositivo de presión arterial automático es una prueba simple y accesible que podría minimizar los sesgos del observador y eliminar la necesidad de capacitación especial. Objetivos: validar la capacidad diagnóstica de un dispositivo oscilométrico automatizado frente al método Doppler para la medición del ITB. Materiales y métodos: se incluyeron pacientes con diabetes mellitus tipo 1 y 2 (DM1 y DM2), mayores de 50 años, con uno o más factores de riesgo cardiovascular. Luego de que los pacientes permanecieran 5 minutos acostados, se registró la presión arterial sistólica (PAS) con tensiómetro Welch Allyn DS 45-11 y Doppler Vascular Contec Sonoline B 8 Mhz en ambas arterias tibiales posteriores y en arteria braquial derecha. Posteriormente se realizaron los mismos registros con monitor de presión arterial automático modelo Omrom HEM-7130. Se calculó el ITB de cada miembro inferior y las capacidades diagnósticas (sensibilidad [S-, especificidad [E], concordancia por coeficiente kappa, valor predictivo positivo [VPP] y valor predictivo negativo [VPN]) del método oscilométrico para detectar un ITB patológico por Doppler (≤0,90). Resultados: se evaluaron 66 pacientes, 52 varones y 14 mujeres, 7 con DM1 y 59 con DM2, 69 años de edad (DS 9,8), con una antigüedad de la DM de 18,05 años (DS 12,01). La prevalencia de EVP detectada por Doppler (ITB ≤0,90) fue del 16,7% (IC 95% 9,9-23,4). El método oscilométrico para detectar un ITB ≤0,90 por Doppler mostró una S del 72,7% (IC 95% 51,8-93,6), una E del 96,3% (IC 95% 92,4-100), una concordancia del 92,4% (IC 95% 87,5-97,3), un VPP del 80,0% (IC 95% 59,9-100) y un VPN del 94,6% (IC 95% 90,0-99,3). Conclusiones: el alto VPN hallado (condición esencial para un método de screening) significa que si el método oscilométrico da un ITB >0,90, hay un 94,6% de posibilidad de que el ITB por Doppler no sea ≤0,90. El VPP de 80% encontrado significa que si el ITB oscilométrico es ≤0,90, hay un 80% de posibilidad de que el ITB Doppler sea verdaderamente ≤0,90. Por lo tanto, consideramos que la simple medición del ITB con el método oscilométrico podría recomendarse en la atención primaria, donde se requieren métodos rápidos, fáciles y confiables.

Introduction: the measurement of the ankle-brachial index (ABI) is a first-line test with high diagnostic accuracy for the detection of peripheral vascular disease. The Doppler method, considered the gold standard, requires the device and a trained operator, which limits its use in primary care. Alternatively, an oscillometric method using an automated blood pressure device is a simple and affordable test that could minimize observer bias and eliminate the need for special training. Objectives: to validate the diagnostic capacity of an automated oscillometric device against the Doppler method for ABI measurement. Materials and methods: diabetes mellitus type 1 and 2 (DM1 and DM2) patients older than 50 years with 1 or more cardiovascular risk factors were included. After 5 minutes lying down, SBP was recorded with a Welch Allyn DS 45-11 sphygmomanometer and Contec Sonoline B 8 Mhz Vascular Doppler in both posterior tibial arteries and in the right brachial artery. Subsequently, the same recordings were made with an Automatic Blood Pressure Monitor Model Omrom HEM-7130. The ABI of each lower limb and the diagnostic capabilities (sensitivity [S], specificity [E], concordance by kappa coefficient, positive predictive value [PPV] and negative predictive value [NPV] of the oscillometric method to detect a pathological ABI were calculated by Doppler (≤0.90). Results: 66 patients were evaluated, 52 men and 14 women, 7 DM1 and 59 DM2, 69 years old (SD 9.8) with a history of diabetes of 18.05 years (SD 12.01). The prevalence of PVD detected by Doppler (ABI ≤0.90) was 16.7% (95% CI 9.9-23.4). The oscillometric method to detect an ABI ≤0.90 by Doppler showed an S of 72.7% (95% CI 51.8-93.6), an E of 96.3% (95% CI 92.4-100), a concordance of 92.4% (95% CI 87.597.3), a PPV of 80.0% (95% CI 59.9-100) and a NPV of 94.6% (95% CI 90 .0-99.3). Conclusions: the high NPV found (essential condition for a screening method) means that if the oscillometric method gives an ABI >0.90, there is a 94.6% chance that the Doppler ABI is not ≤0.90. The PPV of 80% found means that if the oscillometric ABI is ≤0.90, there is an 80% chance that the Doppler ABI is truly ≤0.90. Therefore, we consider that the simple measurement of ABI with the oscillometric method could be recommended in primary care, where fast, easy and reliable methods are adequate.

Lower 25-hydroxyvitamin D (25OHD) levels, diabetes and age are associated with foot and ankle fracture treatment complications

ABSTRACT Objective: This study investigated the nutritional status, 25-hydroxyvitamin D (25OHD), albumin and risk factors associated with complications in patients with foot and ankle fragility fractures. Subjects and methods: Prospective study, developed with patients who suffered fractures due to fragility of the foot and ankle (n = 108); the type of fractured bone, fracture mechanisms and classification were studied and also pseudoarthrosis, treatment, surgical dehiscence, anthropometry, 25OHD and albumin. The Chi-square or Fisher's exact test, Mann-Whitney and Kruskal-Wallis tests were used in the statistical analysis and the multiple logistic regression analysis was used to identify the risk factors associated with complications. Results: The factors that, together, were associated with treatment complications were the level of 25OHD (p = 0.0055; OR = 0.868 [1,152]; 95% CI = 0.786; 0.959 [1.043;1.272]) and diabetes (p = 0.0034; OR = 30,181; 95% CI = 3.087; 295.036). The factors that, together, were associated with the presence of any complication, were age (p = 0.0139; OR = 1.058; 95% CI = 1.011; 1,106) and 25OHD level (p = 0.0198; OR = 0.917; 95% CI = 0.852; 0.986). There was a complication probability above 0.40 associated with lower 25OHD levels (values below 20 ng/mL) and older age (over 50 years). Conclusion: Lower or abnormal levels of 25OHD were associated with pseudoarthrosis, and age and 25OHD were both risk factors for treatment complications in patients with foot and ankle fractures.

Acute ankle injuries: association between sprain severity and ancillary findings

ABSTRACT Objective To correlate the significance of osseous, chondral, tendon, and ligamentous injuries with anatomical variations in low-grade versus high-grade acute ankle sprains. Methods We retrospectively identified the magnetic resonance imaging findings of acute ankle sprains (<15 days). Participants with a history of previous sprains, arthritis, tumors, infections, or inflammatory conditions were excluded. Images were independently evaluated by two musculoskeletal radiologists and assessed for osseous, chondral, tendon, and ligamentous injuries and anatomical variations. Participants were divided into low-grade versus high-grade sprain groups, according to the presence of a complete tear in at least one component of the lateral ligament complex. Results The final study group comprised 100 magnetic resonance images (mean age, 36 years), the majority of males (54%), the right ankle (52%), and a mean sprain duration of 5 days. Participants with high-grade sprains presented with increased rates of medial malleolus edema (p<0.001), moderate and large articular effusions (p=0.041), and shorter calcaneonavicular distance (p=0.008). Complete tears of the anterior talofibular ligament and calcaneofibular ligaments were observed in 100% and 51.2% of the participants in the High-Grade Group, respectively. The deltoid ligament complex was partially torn in this group (55.8% versus 8.8%, p<0.001). Extensor tendon retinaculum lesions occurred significantly more frequently in this group (41.9%) compared to the overall study population (23%) (p<0.001). Conclusion Participants with high-grade ankle sprains presented with shorter calcaneonavicular distances and increased rates of medial malleolus edema, deltoid complex partial tears, extensor retinaculum lesions, and articular effusion.

Different kinesio taping tensions present similar benefits for postural control, dynamic balance, agility and instability sensation in individuals with chronic ankle instability: randomized clinical trial / Diferentes tensões de kinesio taping apresentam benefícios semelhantes para controle postural, equilíbrio dinâmico, agilidade e sensação de instabilidade em indivíduos com instabilidade crônica do tornozelo: ensaio clínico randomizado

Abstract Ankle sprain is the most common injury in the lower limbs of physically active individuals, and one of its complications is chronic ankle instability (CAI), for which Kinesio Taping (KT) can be an alternative treatment. The aim of this study was to compare two treatment protocols with KT at different tensions on postural control, dynamic balance, agility and instability in individuals with chronic ankle instability. This is a randomized clinical trial in which postural control was evaluated through the force platform, agility by the side Hop Test, dynamic balance by the modified Star Excursion balance Test, and application of the Cumberland Ankle Tool Instability and Foot and Ankle Outcome Score to assess self-reported instability and functional instability. An initial assessment was conducted, followed by 5 weeks of intervention with weekly applications of KT, and one week after the completion of the intervention, a reassessment was performed. 21 participants were distributed to the group KT with tension (KTT: n=11) and the group KT without tension (KTWT: n=10). KT improves postural control (anteroposterior velocity: p=0.006 and mediolateral: p<0.001; anteroposterior frequency: p<0.001 and mediolateral: p=0.043 of the area of the center of pressure), dynamic balance (p< 0.001), agility (p=0.001) and feeling of instability in individuals with ICT (p=0.001) for both groups. Only one variable, sports category of the FAOS-FOOT questionnaire showed significant change (p=0.008). KT, with or without tension, is able to improve postural control, balanced balance, postural control, and feelings of instability in young adults with ICT.

Resumo A entorse de tornozelo, uma lesão comum em indivíduos fisicamente ativos, frequentemente resulta em uma complicação chamada instabilidade crônica do tornozelo (ICT). A Kinesio Taping (KT) pode ser uma alternativa de tratamento para essa condição. O objetivo deste estudo foi comparar dois protocolos de tratamento com KT em diferentes tensões no controle postural, equilíbrio dinâmico, agilidade e instabilidade em indivíduos com instabilidade crônica do tornozelo. Trata-se de um ensaio clínico randomizado no qual o controle postural foi avaliado por meio da plataforma de força, a agilidade pelo side Hop Test, o equilíbrio dinâmico pelo Star Excursion balance Test modificado e para avaliar instabilidade funcional e autorrelatada aplicou-se o Foot and Ankle Outcome Score e o Cumberland Ankle Tool Instability. Foi realizada uma avaliação inicial, seguida de 5 semanas de intervenção com aplicações semanais de KT, e uma semana após o término da intervenção, foi realizada uma reavaliação. 21 participantes foram distribuídos para o grupo KT com tensão (KTT: n=11) e o grupo KT sem tensão (KTWT: n=10). KT melhora o controle postural (velocidade ântero-posterior: p=0,006 e médio-lateral: p<0,001; frequência anteroposterior: p<0,001 e médio-lateral: p=0,043 da área do centro de pressão), equilíbrio dinâmico (p<0,001), agilidade (p=0,001) e sensação de instabilidade em indivíduos com ICT (p=0,001) para ambos os grupos. Apenas uma variável, categoria esportiva, do questionário FAOS-FOOT apresentou alteração significativa (p=0,008). O KT, com ou sem tensão, é capaz de melhorar o controle postural, o equilíbrio equilibrado, o controle postural e a sensação de instabilidade em adultos jovens com ICT.
