Bandverbindungen der Dornfortsätze der Wirbelsäule

In the cervical region the fibres of the interspinous and nuchal
ligaments pass in an anteroc ranial direction: they act against
diminishing of the cervical lordosis. In the thoracic region,
longitudinal bundles of fibres connect the tops of the spinous
processes; they act against an augmentation of the thoracal
kyphosis. Between thoracal kyphosis and lumbal lordosis there is no
exact course of the fibres of the interspinous ligts.
("thorakolumbaler "Übergangsbereich"). In the lumbar spine the
fibres of the interspinous ligts., being very strong, pass in a
posterocranial direction. They have the function of limitation the
range of flexion ventrally and of limiting backwards - shifting of
the cranial vertebra in dorsal-flexion. In the lumbosacral segment
additional fibres, arising from the top of the 5th lumbar spinous
process, pass in a posterocaudal direction and interlace with the
thoracolumbar fascia , whose fibres form — below the 4 th
lumbarvertebra — ascissor - latticed structure. The supraspinous
ligt. lies superficially to the thoracolumbar fascia. Its fibres
pass several spinous processes. I t ends caudally at the 4th lumbar
spinous process.
