The lumbosacral joint is a joint of the body, between the last lumbar vertebra and the first sacral segment of the vertebral column. [1] [2] In some ways, calling it a "joint" (singular) is a misnomer, since the lumbosacral junction includes a disc between the lower lumbar vertebral body and the uppermost sacral vertebral body, as well as two lumbosacral facet joints (right and left ...
The lumbosacral ligament or lateral lumbosacral ligament is a ligament that helps to stabilise the lumbosacral joint. The ligament's medial attachment is at (the inferior border of) transverse process of lumbar vertebra L5; its lateral attachment is at the ala of sacrum .
The Milwaukee brace, also known as a cervico-thoraco-lumbo-sacral orthosis or CTLSO, is a back brace most often used in the treatment of spinal curvatures (such as scoliosis or kyphosis) in children but also, more rarely, in adults to prevent collapse of the spine and associated pain and deformity. It is a full-torso brace that extends from the ...
The Boston brace, a type of thoraco-lumbo-sacral-orthosis (TLSO), [1] is a back brace used primarily for the treatment of idiopathic scoliosis in children. [2] It was developed in 1972 by M.E "Bill" Miller and John Hall at the Boston Children's Hospital in Boston, Massachusetts. [2]
[2]: 45 It is thicker and broader in the lumbar region than in the thoracic region, and intimately blended with the neighboring fascia in both these regions. [3] Inferior to L4, the supraspinous ligament becomes indistinct, lost amid the prominent lumbar fascia. [4] J: Supraspinous ligament
The lumbar enlargement (or lumbosacral enlargement) is a widened area of the spinal cord that gives attachment to the nerves which supply the lower limbs. It commences about the level of T11 and ends at L2, and reaches its maximum circumference, of about 33 mm. Inferior to the lumbar enlargement is the conus medullaris. [1]
The sacrum is curved upon itself and placed very obliquely, its base projecting forward and forming the prominent sacrovertebral angle when articulated with the last lumbar vertebra. It is also known as the "lumbosacral angle". [1]
The anterior longitudinal ligament extends superoinferiorly between the basiocciput of the skull and the anterior tubercle of the atlas (cervical certebra C1) superiorly, and the superior part of the sacrum inferiorly; [1] inferiorly, it ends at the sacral promontory. [2] It broadens inferiorly. [1]
