Microdiscectomia lombar: acessos interlaminar e intertransverso com uso de afastador de Caspar tubular cilíndrico e dreno de Penrose como auxiliar no afastamento da musculatura – estudo de 502 casos

Resumo

Os autores fazem uma revisão da literatura abordando conhecimentos neuroanatômicos da raiz e do gânglio da raiz dorsal. Descrevem a técnica para os acessos interlaminar e intertransverso com o uso de afastador de Caspar tubular cilíndrico e dreno de Penrose como auxiliares no afastamento da musculatura. Basearam-se em 502 casos operados em 25 anos. O objetivo deste trabalho é descrever uma técnica com incisão pequena na pele, baixa agressividade para as estruturas anatômicas, sem perda funcional da musculatura paravertebral, campo cirúrgico amplo, facilidade de execução com as duas mãos, alta hospitalar precoce em torno de 24 horas e baixo custo.

Abstract

The authors review the literature addressing neuro-anatomical knowledge of the root and root ganglion dorsal. Describe the technique for the interlaminar and intertransverso access using tubular retractor Caspar cylindrical Penrose drain as an aid in muscular retraction. Based-seem 502 cases operated in 25 years. The objective of this paper is to describe a technique with small skin incision, low aggressiveness anatomical structures without functional loss of paraspinal musculature, broad surgical field, easy work with both hands, high early hospital about 24 hours and low cost.
