sacrospinalis

sacrospinalis

[sak′rōspīnal′is]
Etymology: L, sacer + spina, backbone
the superficial longitudinal muscle mass on either side of the vertebral column. It is sheathed in the fascia thoracolumbalis and arises in a broad, thick tendon from the sacrum, the ilium, and the lumbar vertebrae. It inserts into the ribs and into certain cervical vertebrae and is innervated by the branches of the dorsal primary divisions of the spinal nerves. It extends and flexes the vertebral column and the head, draws the ribs downward, and bends the trunk to the side. Also called erector spinae, sacrospinal muscle.

sacrospinalis

(sā″krō-spī-nāl′ĭs) [″ + spina, thorn]
A large muscle group lying on either side of the vertebral column extending from the sacrum to the head. Its two chief components are the iliocostalis and longissimus muscles.

After the removal of the balloon, 2 working ports, 11 mm and 5 mm in size, were inserted under finger guidance, one in the renal angle just below the 12th rib at the lateral border of the sacrospinalis muscle, and the other was inserted 11 mm above and anterior to the anterior superior iliac spine.
This has also been my experience with the needle, and it stands to reason--no stimulus would be expected with injection into the CSF or epidural vein, or other "soft spot" like the sacrospinalis muscle.

Some scholars thought the scar tissue around dura mater of the spinal cord was originated from the posterior injured sacrospinalis and the anterior injured anulus fibrosus as well as the posterior longitudinal ligament.
