Se estudia histológicamente el desarrollo del cerebelo en la rata y se compara cronológicamente con el humano. El cerebelo deriva del rombencéfalo y su esbozo se establece en E.sub.r15d/E.sub.h8s ...(Embrión días/semanas). La fuente de neuronas en el cerebelo es: 1) región subventricular, desde donde migran radialmente los precursores de las neuronas de Purkinje hacia la parte más dorsal del esbozo cerebeloso, formando múltiples capas (E.sub.r18d/E.sub.h13s), para más adelante organizarse en una sola hilera (P.sub.r6d/E.sub.h30s; Postnatal); 2) parte rostral del labio rómbico, a partir del cual y por migración tangencial hacia la zona dorsal, se genera la capa granular externa (EGL) (E.sub.r17d/E.sub.h10s). Desde la EGL, los granos migran hacia la profundidad sobrepasando los somas de Purkinje, para constituir la capa granular interna (IGL) (P.sub.r0-1d/E.sub.h20s). Posteriormente la EGL desaparece (P.sub.r20d/P.sub.h7meses), estableciéndose una única capa granular. La laminación primaria se inicia en E.sub.r20-21d/E.sub.h12s y la secundaria en P.sub.r0-1d/E.sub.h15s. Palabras clave: cerebelo, desarrollo, embrión, postnatal. We study the histological cerebellar development in rats and we compared it chronologically to humans. The cerebellum derives from the hindbrain, and its origin occurs in Er15d/Eh8w (embryo days/weeks). Sources of neurons in the cerebellum are: 1) subventricular region where precursors of Purkinje neurons migrate radially towards to the dorsal surface of the cerebellar anlage, where they organize in several layers (E.sub.r18d/E.sub.h13w). Later, Purkinje neurons arranged in a unique layer (P.sub.r6d/E.sub.h30w; Postnatal); 2) rostral part of the rhombic lip, from which granule cells precursors migrate tangentially to constitute the external granular layer (EGL) located next to the dorsal area of the cerebellar anlage (E.sub.r17d/E.sub.h10w). EGL granule cells migrate to a deeper possition, overcoming the Purkinje layer to form the internal granule layer (IGL) (P.sub.r0-1d/E.sub.h20w). Subsequently EGL disappears (P.sub.r20d/P.sub.h7months), establishing a single granular layer. The primary lamination starts in E.sub.r20-21d/E.sub.h12w and secondary lamination in P.sub.r0-1d/E.sub.h15w. Key words: cerebellum, development, embryo, postnatal.
La artrodesis de la articulación metatarsofalángica del hallux es una intervención quirúrgica indicada para el tratamiento de diversas dolencias, cuyo objetivo es aliviar el dolor y mejorar el apoyo ...del primer radio. Existen diversas técnicas quirúrgicas y métodos de fijación para llevar a cabo la artrodesis de dicha articulación, siendo la combinación de placa dorsal y tornillo interfragmentario la que ha demostrado en diversos estudios biomecánicos mayor estabilidad. Nuestro objetivo es analizar los resultados radiológicos tras artrodesis metatarsofalángica del hallux utilizando placa dorsal asociada o no a tornillo interfragmentario, valorando las diferencias en relación con la consolidación y las complicaciones en pacientes diagnosticados de hallux rigidus, hallux valgus, hallux varus y fracaso de cirugías previas.
Realizamos un estudio de cohortes retrospectivo de 55 casos con una edad media de 65,10 años, intervenidos de una artrodesis de la articulación metatarsofalángica del hallux con placa dorsal, divididos en 2 grupos de estudio, según asocien o no tornillo de compresión sin cabeza, con un seguimiento de al menos 6 meses postoperatorios. Valoramos los resultados radiológicos pre y postoperatorios basándonos en la variación de los ángulos estudiados (ángulo del hallux, ángulo intermetatarsal y ángulo metatarsofalángico dorsal del primer dedo), así como los casos de seudoartrosis encontrados en cada grupo de estudio.
En cuanto a los resultados radiológicos, únicamente se encuentran diferencias estadísticamente significativas (p<0,05) en relación con el ángulo de dorsiflexión posquirúrgico entre ambos grupos de estudio. No se encontraron diferencias estadísticamente significativas en relación con el análisis radiológico del ángulo del hallux e intermetatarsal pre y posquirúrgico, ya que se observa que disminuyen igual en ambos grupos de estudio. El grupo A, que asocia tornillo interfragmentario, presentó una tasa de consolidación del 92%, frente al grupo B, sin tornillo a compresión, que fue del 63%, siendo estas diferencias estadísticamente significativas (p<0,05).
La artrodesis metatarsofalángica del hallux con placa dorsal asociada a tornillo interfragmentario obtiene mejores resultados en lo que se refiere a consolidación y complicaciones respecto a aquellos casos en los que no se utiliza el tornillo interfragmentario.
The first metatarsophalangeal joint arthrodesis is indicated for the treatment of various pathologies as a technique to reduce pain and improve the support of the first radius. Numerous surgical techniques and fixation methods have been described, with the combination of a dorsal plate and an interfragmentary screw being the one that has shown to be the most stable construct in biomechanical studies. Our aim is to analyze the radiological results after metatarsophalangeal arthrodesis of the hallux using a dorsal plate associated or not with an interfragmentary screw. The differences in terms of consolidation rates and complications in patients diagnosed with hallux rigidus, hallux valgus, hallux varus and failure of previous surgeries were evaluated.
A retrospective cohort study of 55 patients with a mean age of 65.10 years in whom a dorsal plate was used was performed. Patients were divided into 2 groups depending on whether or not an interfragmentary screw was used. The minimum follow-up was 6 months after surgery. The assessment of the pre and postoperative radiological results was based on the variation of the hallux angle, the intermetatarsal angle and the dorsal metatarsophalangeal angle of the hallux, as well as the cases of nonunion identified in each study group.
The radiological results, statistically significant differences (p<0.05) were only found in the dorsal metatarsophalangeal angle between both study groups. No statistically significant differences were found regarding the radiological evaluation of the pre and postoperative hallux angle and intermetatarsal angle. An equal decrease of each angles was observed in both study groups. Regarding the consolidation rate, statistically significant differences (p<0.05) were found between group A, which associated an interfragmentary screw, presenting a consolidation rate of 92%, and group B, which did not associate an interfragmentary screw, and that presented a union rate of 63%.
Hallux metatarsophalangeal arthrodesis of the hallux with a dorsal plate and interfragmentary screw show best results regarding consolidation rate and complications compared to those cases in which an interfragmentary screw was not used.
To present a series of patients with elastofibroma dorsi (ED) in order to recall the pathology and justify its diagnostic and therapeutic management in the primary care setting.
Retrospective ...observational and longitudinal study of 12 patients with 18ED. Epidemiological, clinical and imaging characteristics were analysed. Treatment outcomes were assessed in terms of pain (VAS scale), shoulder function (Constant and Murley scale) and quality of life (EuroQol-5 dimension scale, EQ-5D). The mean follow-up of the cases was 60.5months (5years, range 1-161months).
Six patients were male and six were female, with a mean age at diagnosis of 59years. The diagnosis of suspicion in all cases was based in clinical and imaging findings. Only three required surgery. The results of all were satisfactory.
Both the diagnosis and the indication for treatment of an ED can be made in the primary care setting. In typical cases, which are the majority, the clinical history and an ultrasound study allow a diagnosis of certainty. The indication for conservative or surgical treatment depends on the informed patient. When there are diagnostic doubts or the patient wishes surgical resection of the tumour, the patient should be referred to a hospital specialist.

En el desarrollo del pie plano valgo adquirido del adulto ha cobrado gran importancia el fallo de la columna medial, y no tanto la rotura del tibial posterior, siendo principalmente la lesión del ...ligamento en hamaca calcaneonavicular (spring ligament) el determinante del desarrollo de esta deformidad.
Nuestro objetivo es analizar los resultados clínico-radiológicos de la reparación del ligamento en hamaca y valorar la utilidad e integración de las cuñas de titanio poroso en las osteotomías a las que se asocia la reparación ligamentosa.
Realizamos un estudio retrospectivo de 23 casos con una edad media de 63 años, diagnosticados de pie plano valgo adquirido del adulto estadio IIB de la clasificación RAM tras fallo de tratamiento ortoprotésico, valorando los resultados clínicos mediante la escala de la American Orthopaedic Foot and Ankle Society y los resultados radiológicos pre- y postoperatorios basándose en la variación de los ángulos estudiados (cobertura talonavicular y ángulo talar - 1.° metatarsiano en la proyección dorsoplantar y línea de Meary en la proyección lateral).
Los puntuación media en escala de la American Orthopaedic Foot and Ankle Society pasó de 52±10 preoperatorio a 88±6 (p<0,05). En cuanto a los resultados radiológicos, se demostró una mejoría estadísticamente significativa (p<0,05) en la variación de los ángulos en el postoperatorio.
La reparación de los estabilizadores mediales, asociada a técnicas óseas ofrece excelentes resultados clínico-radiológicos en el tratamiento del pie plano valgo adquirido del adulto estadio IIB.
Además, las cuñas de titanio poroso presentan una adecuada integración, evitando los problemas de pinzamiento de los peroneos asociada al uso de placas y la necesidad posterior de retirada.
The spring ligament has paramount role in supporting the arches and its fail causes the collapse of the medial longitudinal arc, inducing adult acquired flatfoot deformity. Our aim was to analyze the clinical and radiological outcomes of spring ligament repair and titanium wedges integration used in surgical osteotomies.
We performed a retrospective study of 23 cases with middle ages of 63, diagnosed with adult acquired flatfoot deformity stage IIB in RAM classification after ortho-prosthetic treatment failure, assessing the functional outcomes using the American Orthopedic Foot and Ankle Society scale and the radiological outcomes studying angles variation (talonavicular uncoverage, talo-first metatarsal angle and Meary axis).
The mean preoperative American Orthopedic Foot and Ankle Society score of the sample was 52±10 and the postoperative 88±6 (p<0.05). The radiological outcomes showed a statistically significant improvement.
Spring ligament repair associated to bone reconstruction offers large functional and radiological outcomes to adult acquired flatfoot deformity stage IIB treatment. Titanium wedges present an excellent bone integration.
