What is spinal cord Untethering?
Tethered spinal cord syndrome is a neurologic disorder caused by tissue attachments that limit the movement of the spinal cord within the spinal column. These attachments cause an abnormal stretching of the spinal cord. This syndrome is closely associated with spina bifida.
What is Fibrolipoma of filum terminale?
Fatty filum terminale, also known as lipoma of the filum terminale or filar lipoma, is a relatively common finding on imaging of the lumbar spine, and in most cases is an incidental finding of no clinical concern. However, in some patients it may be associated with signs and symptoms of tethered cord syndrome.
What is sectioning of the filum terminale?
A section of the filum terminale (SFT) is used for the surgical treatment of isolated tethered cord or that resulting from neurulation disorders. More recently, it has been proposed for the management of the occult tethered cord syndrome (OTCS), though it is still under debate.
What is VBT for scoliosis?
Vertebral body tethering (VBT) is a surgical treatment for idiopathic scoliosis in growing children whose scoliosis continues to progress despite bracing. The treatment was approved by the FDA in August 2019.
Where does the filum terminale attach?
coccyx
The lower part, or filum terminale externum, closely adheres to the dura mater. It extends downward from the apex of the tubular sheath and is attached to the back of the first segment of the coccyx in a structure sometimes referred to as the coccygeal ligament.
What is filum terminale function?
The filum terminale (FT) is a fibrous band that extends from the conus medullaris to the periosteum of the coccyx, and its functions are to fixate, stabilize, and buffer the distal spinal cord from normal and abnormal cephalic and caudal traction.
Which accurately describes the filum terminale?
The filum terminale (“terminal thread”) is a delicate strand of fibrous tissue, about 20 cm in length, proceeding downward from the apex of the conus medullaris. It is one of the modifications of pia mater.
Where does the Filum terminale attach?
What is VBT in chemistry?
Valence bond (VB) theory assumes that all bonds are localized bonds formed between two atoms by the donation of an electron from each atom. Valence Bond theory describes covalent bond formation as well as the electronic structure of molecules.
What is VBT ASC?
There are two procedures of spinal tethering known as Anterior Scoliosis Correction (ASC) and Vertebral Body Tethering (VBT), the only difference is the eligibility criteria.
