LUW explained

Brief explanation of the SV LUW Health Test - written by David Payne.

During the assessment, it is checked whether a lumbo-sacral transition vertebrae is present.

Transitional vertebrae have features of both the previous and the following spinal column section. Lumbosacral transition vertebrae (LUW), occur between the lumbar spine and sacrum (lumbosacral). Especially in the area of the vertebral arches and the transverse processes, they show a shape that deviates from the norm.

The investigation distinguishes between  four types : type 0 (normal anatomy), types 1, 2 and 3.

In Type 1, L7 (last lumbar vertebra) and S1 (first sacral vertebra) behave as in the normal lumbosacral junction, but there is an isolated one Spinous process at S1

Type 2  includes the more pronounced forms of the LUW with variations in the vertebral anatomy at L7 and /or S1. The changes can occur very differently. They are designed symmetrically here . The transitions are fluid here.

Type 3 includes the asymmetrical forms of the LUW.
