Abstract
The transfer of part of the ulnar nerve to the musculocutaneous nerve, first described by Oberlin, can restore flexion of the elbow following brachial plexus injury. In this study we evaluated the additional benefits and effectiveness of quantitative electrodiagnosis to select a donor fascicle. Eight patients who had undergone transfer of a simple fascicle of the ulnar nerve to the motor branch of the musculocutaneous nerve were evaluated. In two early patients electrodiagnosis had not been used. In the remaining six patients, however, all fascicles of the ulnar nerve were separated and electrodiagnosis was performed after stimulation with a commercially available electromyographic system. In these procedures, recording electrodes were placed in flexor carpi ulnaris and the first dorsal interosseous. A single fascicle in the flexor carpi ulnaris in which a high amplitude had been recorded was selected as a donor and transferred to the musculocutaneous nerve. In the two patients who had not undergone electrodiagnosis, the recovery of biceps proved insufficient for normal use. Conversely, in the six patients in whom quantitative electrodiagnosis was used, elbow flexion recovered to an M4 level.
Quantitative intra-operative electrodiagnosis is an effective method of selecting a favourable donor fascicle during the Oberlin procedure. Moreover, fascicles showing a high-amplitude in reading flexor carpi ulnaris are donor nerves that can restore normal elbow flexion without intrinsic loss.

Premios Semergen (I): lesiones en la práctica profesional de la guitarra
http://www.condroprotectores.es/premios-semergen-i-lesiones-en-la-practica-profesional-de-la-guitarra/
Conocer la incidencia de lesiones en la práctica profesional de la guitarra y determinar las posibles causas que contribuyen a su aparición. Este fue el objetivo de un estudio descriptivo realizado por la Dra. Milagros Lucas, Médico Residente de Medicina Familiar y Comunitaria del Centro de Salud San Fernando de Badajoz. El trabajo ha sido premiado con una de las becas a la investigación en artrosis y condroprotección que Semergen otorgó durante su congreso nacional el pasado mes de octubre.
Premios Semergen (I): lesiones en la práctica profesional de la guitarra
Para el estudio se realizó una encuesta ad hoc para los participantes de uno de los Concursos Internacionales realizados en Extremadura en 2012. Los resultados mostraron que:
- El 88% de los encuestados había presentado alguna enfermedad relacionada con la práctica musical, predominando la patología a nivel de columna vertebral.
- El 40% realizaba estiramientos antes de tocar, el 32% a veces y el 28% nunca.
- Solamente el 64% consultó con un profesional sanitario (un 82% a su médico de atención primaria y un 36% a un fisioterapeuta).
Por todo ello, el estudio recomienda la realización de estiramientos previos a la interpretación musical desde la infancia, así como la adopción de posiciones adecuadas al toca, para evitar posibles lesiones músculo esqueléticas.
