sacrospinaal

Sacrospinaal is an anatomical term used in Dutch to describe something relating to both the sacrum and the spine. The prefix sacro- refers to the sacrum, while spin- or spinal- refers to the spine, and the suffix -aal forms an adjective. The term functions as a descriptive label rather than naming a single distinct structure.

In practice, sacrospinaal is found in compound terms that designate structures associated with the sacral region and the vertebral column. Examples in historical and teaching literature include references to the sacrospinalis or sacrospinaal muscle group, which corresponds to the erector spinae muscles that run along the back. The adjective is also used in discussion of ligaments and fascia in the lumbosacral area, where connections between the sacrum and the spine form part of the supporting framework of the pelvis and posterior trunk.

Because sacrospinaal is a descriptive adjective, its exact usage can vary between authors and textbooks. It does not denote a single distinct anatomical entity, but rather a relation or group of structures that lie in the region where the sacrum meets the spinal column. When encountered, the term is typically understood from the context of the described structure or region.

References are found in standard anatomical dictionaries and Dutch medical texts that cover the vertebral column and pelvic region.
