The triangular fibrocartilage disc (TFC) is an articular discus that lies on the pole of the distal ulna. It has a triangular shape and a biconcave body; the periphery is thicker than its center. It has a triangular shape and a biconcave body; the periphery is thicker than its center.
An intervertebral disc (British English), also spelled intervertebral disk (American English), lies between adjacent vertebrae in the vertebral column.Each disc forms a fibrocartilaginous joint (a symphysis), to allow slight movement of the vertebrae, to act as a ligament to hold the vertebrae together, and to function as a shock absorber for the spine.
If hyaline cartilage is torn all the way down to the bone, the blood supply from inside the bone is sometimes enough to start some healing inside the lesion. In cases like this, the body will form a scar in the area using a special type of cartilage called fibrocartilage. [2]
The straight leg raise test is almost always positive in those with disc herniation, [5] and lumbar provocative discography may be useful to identify a specific disc causing pain in those with chronic high levels of low back pain. [47] Therapeutic procedures such as nerve blocks can also be used to determine a specific source of pain. [5]
Intradural disc herniation occurs when the disc material crosses the dura mater and enters the thecal sac. It is a rare form of disc herniation with an incidence of 0.2–2.2%. Pre-operative imaging can be helpful for diagnosis, but intra-operative findings are required for confirmation. [26]
Percutaneous disc decompression: A procedure that reduces or eliminates a small portion of the bulging disc through a needle inserted into the disc, minimally invasive. Spinal decompression: A non-invasive procedure that temporarily (a few hours) enlarges the intervertebral foramen (IVF) by aiding in the rehydration of the spinal discs.
[9] [10] This occurs ~2 1/2 months following injury, without associated neurological symptoms or pain, and typically resolves within 1 year. [ citation needed ] This sign is also sometimes seen as part of a " discontinuation syndrome " associated with certain psychotropic medications, such as selective serotonin reuptake inhibitors and ...
Lumbar disc disease is the drying out of the spongy interior matrix of an intervertebral disc in the spine. Many physicians and patients use the term lumbar disc disease to encompass several different causes of back pain or sciatica. In this article, the term is used to describe a lumbar herniated disc.
