Transferencia de la cabeza larga del tríceps para la flexión del codo en secuela de lesiones del plexo braquial / Transfer of the long head of triceps for elbow flexion in braquial plexus sequelae

Resumen: La anatomía neurovascular independiente de la cabeza larga del tríceps braquial y su idoneidad como un colgajo muscular libre han sido ampliamente estudiadas. En cambio, la trasposición de esta porción del tríceps para mejorar la flexión de codo ha sido descrita pocas veces. Se describen en este artículo dos casos de secuela de lesión del plexo braquial, en los que se realizó trasposición únicamente de la cabeza larga del tríceps. Se logró mejorar la flexión del codo y se conservó la extensión del mismo.

Abstract: The independent neurovascular anatomy of the long head of the triceps brachii and its suitability as a free muscle transfer have been extensively studied. Instead muscle transposition of the long head of the triceps brachii to enhance elbow flexion has been rarely described. We describe in this paper two cases of injury of brachial plexus sequel in which transposition was performed only on the long head of the triceps. The elbow flexion was improved, the extension was preserved.

High prevalence of neuropathic pain in the hand of patients with traumatic brachial plexus injury: a cross-sectional study / Alta prevalência de dor neuropática em sujeitos com lesão traumática do plexo braquial: um estudo de corte transversal

ABSTRACT Objective To describe the pain profile of patients with traumatic brachial plexus injury. Methods We enrolled 65 patients with traumatic brachial plexus injury. The Douleur Neuropathique 4 questionnaire was used to classify pain and the SF-36 was used to evaluate quality of life. Results The patients with traumatic brachial plexus injury were predominantly young male victims of motorcycle accidents. Pain was present in 75.4% of the individuals and 79% presented with neuropathic pain, mostly located in the hands (30.41%). The use of auxiliary devices (p = 0.05) and marital status (p = 0.03) were both independent predictors of pain. Pain also impacted negatively on the quality of life (p = 0.001). Conclusions Pain is frequent in patients with traumatic brachial plexus injury. Despite the peripheral nervous system injury, nociceptive pain is not unusual. Pain evaluation, including validated instruments, is essential to guide optimal clinical management of patients with the condition.

RESUMO Objetivo Descrever o perfil de dor de sujeitos com lesão traumática do plexo braquial. Métodos Nós incluímos 65 indivíduos com lesão traumática do plexo braquial. O Douleur Neuropathique 4 foi usado para classificar a dor e o SF-36 foi usado para avaliar a qualidade de vida. Resultados Sujeitos com lesão traumática do plexo braquial eram em sua maioria homens jovens, vítimas de acidentes motociclísticos. A dor esteve presete em 75.4% dos indivíduos e 79% deles apresentaram dor neuropática, mais frequentemente localizada nas mãos (30.41%). O uso de dispositivos auxiliares (p = 0.05) e o estado civil foram, ambos, preditores independentes de dor. A dor ainda impactou negativamente da qualidade de vida (p = 0.001). Conclusões A dor é frequente em sujeitos com lesão traumática do plexo braquial. Apesar de envolver uma lesão do sistema nervoso a dor nociceptiva não é infrequente. A avaliação da dor, incluindo instrumentos validados, é essencial para direcionar as condutas clínicas de sujeitos com esta condição.

Comparacion de tecnicas de reconstruccion empleadas en cirugia de plexo braquial entre las lesiones supra e infraclaviculares / Comparison of brachial plexus surgical reconstruction techniques used between supra and infraclavicular lesions

Objective: to compare the thecnical procedures used for reconstruction in different groups of traumatic brachial plexus lesions (TBPL): supra and infraclavicular. Methods: all cases of brachial plexus lesions operated between September 2002 and March 2004 were included. Each case was analyzed separately and included in one of the two groups. Results: a total of 12 lesions were included in this presentation. Out of these, 8 were supraclavicular lesions, wich required neurorraphy in 4 nerves or trunks, neurotization in 11, and neurolisis in one. There were 4 infraclavicular lesions: 4 required neurolisis, and 2 neurorraphy. Conclusion: Eachs group of TBPL required a different surgical reconstruction technique
