Association between anterior talofibular ligament injury and ankle tendon, ligament, and joint conditions revealed by magnetic resonance imaging.

BACKGROUND: The lateral ankle ligament complex is the most frequently injured ligament secondary to strong ankle inversion movement during lateral ankle sprains (LAS). Among these injuries, anterior talofibular ligament (ATFL) injury is the most frequent condition (present in 66-85% of such injuries). The purpose of this research was to use magnetic resonance imaging (MRI) to determine the association between ankle tendon, ligament, and joint conditions and ATFL injuries. METHODS: A case-control MRI study was carried out to compare the presence of ankle muscle, tendon, ligament, and joint conditions in patients with injured ATFLs (case group; n=25) and non-injured ATFLs (control group; n=25). RESULTS: Achilles tendinopathy was present in 1/25 (4%) patients with injured ATFLs and 7/25 (28%) non-injured ATFL subjects (P=0.048). Injured calcaneofibular ligaments (CFLs) were present in 19/25 (76%) patients with injured ATFLs and 1/25 (4%) non-injured ATFL subjects (P<0.001). Finally, injured tibiotalar joints were present in 16/25 (64%) patients with injured ATFLs and 5/25 (20%) non-injured ATFL subjects (P=0.002). Other musculoskeletal structure injuries occurred at similar rates between patients with injured ATFLs and those with non-injured ATLFs (P≥0.05). CONCLUSIONS: Patients with ATFL injuries showed a greater presence of CFL and tibiotalar joint injuries than subjects with non-injured ATFLs.

Intra and Inter-rater Reliability between Ultrasound Imaging and Caliper Measures to determine Spring Ligament Dimensions in Cadavers.

The purpose was to evaluate intra and inter-rater reliability, repeatability and absolute accuracy between ultrasound imaging (US) and caliper measures to determine Spring ligament (SL) dimensions in cadavers. SLs were identified from 62 human feet from formaldehyde-embalmed cadavers. Intra and inter-observer reliability, repeatability and absolute accuracy of SL width, thickness and length between US and caliper measurements were determined at intra and inter-session by intraclass correlation coefficients, Pearson´s correlation coefficients, Student t tests, standard errors of measurement, minimum detectable changes, values of normality, 95% limits of agreement, and Bland-Altman plots. Excellent inter-session and inter-rater reliability, adequate absolute accuracy, almost perfect agreement and strong correlations were shown for caliper, US and their comparison for all SL dimensions. US measurements presented higher absolute accuracy than caliper measures for SL length and thickness dimensions, while caliper displayed greater absolute accuracy for SL width dimensions. Good repeatability (P > 0.05) was shown for all SL dimensions by US, caliper and their comparison, except for SL width dimension measured with US (P = 0.019). Both US and caliper could be recommended for all SL dimensions evaluation due to their excellent reliability and absolute accuracy in cadavers, although width dimensions should be considered with caution due to US repeatability differences.

Estudios experimentales de la biomecánica de la marcha durante el embarazo: revisión sistemática de ensayos clínicos. (2000-2018) / Experimental studies of gait biomechanics during pregnancy: Systematic review of clinical trials. (2000-2018)

Background: El embarazo es un momento en la vida de la mujer cuyos cambios fisiológicos, hormonales, y morfológicos generan grandes cambios corporales. Estos cambios se producen en un periodo de tiempo muy corto y provocan una pérdida de estabilidad y de cambios cinemáticos y cinéticos en su marcha que generan caídas y molestias musculoesqueléticas en el miembro inferior y pie. Métodos: Se ha realizado una revisión de la literatura científica para identificar los posibles estudios científicos sobre la marcha y embarazo. Se han consultado los principales buscadores y bases de datos biomédicas: Medline-pubmed, Enfispo, Scielo y Science Direct(R). El periodo de búsqueda estuvo comprendido febrero-junio de 2018. Resultados: En nuestra búsqueda hallamos 912 resúmenes de artículos con las palabras clave seleccionadas. 892 artículos de los anteriormente mencionados fueron excluidos tras leerlos por no cumplir los criterios de selección del estudio. Por lo tanto, obtuvimos 20 relevantes. Conclusión: Existen estudios experimentales que evidencian cambios en la cinemática, cinética de la marcha del tronco, pelvis, miembro inferior y pie en el embarazo y postparto

Background: Pregnancy is a moment in a woman's life whose physiological, hormonal, and morphological changes generate great bodily changes. These changes occur in a very short period of time and cause a loss of stability and a series of kinematic and kinetic changes in their gait that cause falls and musculoskeletal discomfort in the lower limb and foot. Methods: A review of the scientific literature has been carried out to identify possible scientific studies on gait and pregnancy. The main biomedical search engines and databases were consulted: Medline-Pubmed, Enfispo, Scielo and Science Direct®. The search period was comprised February-June 2018. Results: In our search we found 912 summaries of articles with the selected keywords. 892 articles of the aforementioned were excluded after reading them because they did not meet the selection criteria of the study. Therefore, we obtained 20 relevant. Conclusion: There are experimental studies that show changes in the kinematics, kinetics of the trunk, pelvis, lower limb and foot in pregnancy and postpartum
