Abstract

The paraspinal space is intriguing in nature. There are several needle tip placements described in compact anatomical spaces. This has led to an incertitude regarding the appropriate anatomic locations for needle tip positions. Through our cadaver models we try to resolve the issues surrounding needle tip positions clarifying anatomical spaces and barriers. Further we propose an anatomical classification based on our findings in cadaveric open dissections and cross and sagittal sections.

Keywords

Cadaver;  Dissection;  Nerve block;  Paraspinal Muscles;  Regional Anesthesia;  Ultrasound

Resumo

O espaço paraespinhal é intrigante por natureza. Existem vários posicionamentos de pontas de agulha descritos em espaços anatômicos compactos. Isto levou a uma incerteza quanto aos locais anatômicos apropriados para as posições da ponta da agulha. Através dos nossos modelos de cadáveres tentamos resolver os problemas relacionados com a posição das pontas das agulhas, clarificando espaços e barreiras anatómicas. Além disso, propomos uma classificação anatômica baseada em nossos achados em dissecções abertas de cadáveres e cortes transversais e sagitais.
