Extensor digitorum brevis manus: a raremuscle on the dorsum of the hand

The extensor digitorum brevis manus is one of the rare anatomic variations which occur on the dorsum of the hand. Only some 295 articles were found worldwide in an extensive bibliographic review carried out in 2003. This muscle was dissected bilaterally on a male corpse at the Human Anatomy Laboratory of the Morphophysiological Department of the “Faculty of Medical Sciences of Minas Gerais”. It is an elongated, small muscle, originating at the carpal bones and at the extensor retinaculum and inserting into one of the tendons of the finger’s extensor muscle. Even though it does not present an essential function in the movement of the fingers nor the hand, it can lead to pain when hypertrophied, creating the need for clinical or even surgical treatment.

Dermolipectomias dorsais altas: técnicas e resultados / Upper dorsal dermolipectomies: techniques and results

Grandes emagrecimentos ou lipoaspirações de grandes volumes ocasionam o aparecimento de dobras cutâneas bastante desgraciosas na região dorsal. Em virtude de o tratamento desse problema exigir ressecções cutâneas com cicatrizes extensas, sem dobras cutâneas para dissimulá-las, pouco tem sido abordado sobre esse tipo de tratamento a não ser para casos severos de grandes perdas ponderais. Os autores apresentam técnica de excisão transversal, discutem considerações técnicas e apresentam resultados e a aplicabilidade para casos moderados.

Large weight loss or large volume liposuction may cause skin folds in the upper dorsal region. To correct that problem is necessary to excise skin, resulting large scars difficult to hide. For this reason the treatment is performed rarely and few papers are published about the theme and only in severe cases. The authors present the surgical treatment for mild and severe cases discussing indications, technique considerations and present results.

Dinamometria manual y espinal en escolares cubanos de 5 a 16 anos / Manual and spinal dynamometry in 5- to 16- year old Cuban school children

Se estudiaron 3 863 escolares de las provincias Habana, Ciudad de la Habana, Cienfuegos y Santiago de Cuba, en las edades comprendidas entre 5 y 16 anos; 1 867 del sexo femenino y 1 996 del sexo masculino. Se mostro el comportamiento de la fuerza muscular y los valores encontrados entre el 25 y 75 percentil para cada variable segun grupos de edades y sexos. Se detecto en este estudio que la fuerza muscular de ambas manos y de los musculos de la espalda es superior en el sexo masculino y que se incrementa a medida que evoluciona el desarrollo fisico. Los valores de las dinamometrias manual y espinal ubicados entre los percentiles 25 y 75, podran servir de medidas de referencia de la fuerza muscular, pues en la actualidad no se cuenta con normas cubanas de esta medida fisiometrica
