| annulus fibrosus of intervertebral disc | The ring of fibrocartilage and fibrous tissue forming the circumference of the intervertebral disc; surrounds the nucleus pulposus, which is prone to herniation when the annulus fibrosus is compromised. Synonym: annulus fibrosus disci intervertebralis, annulus fibrosus, fibrous ring of intervertebral disc, fibrous ring. (05 Mar 2000) |
| articular disc | A plate or ring of fibrocartilage attached to the joint capsule and separating the articular surfaces of the bones for a varying distance, sometimes completely; it serves to adapt two articular surfaces that are not entirely congruent. Synonym: discus articularis, articular disk, fibrocartilago interarticularis, fibroplate, interarticular fibrocartilage, intra-articular cartilage. (05 Mar 2000) |
| articular disc of acromioclavicular joint | The articular disk of fibrocartilage usually found between the acromial end of the clavicle and the medial border of the acromion. Synonym: discus articularis acromioclavicularis, acromioclavicular disk, Weitbrecht's cartilage. (05 Mar 2000) |
| articular disc of distal radioulnar joint | The disk that holds together the distal ends of the radius and ulna; it is attached by its apex to a depression between the styloid process and distal surface of the head of the ulna, and by its base to the ridge separating the ulnar notch from the carpal surface of the radius. Synonym: discus articularis radioulnaris, radioulnar disk, radioulnar articular disk, triangular cartilage, triangular disk of wrist, triquetrous cartilage. (05 Mar 2000) |
| articular disc of sternoclavicular joint | The fibrocartilaginous disk that subdivides the sternoclavicular joint into two cavities. Synonym: discus articularis sternoclavicularis, sternoclavicular disk, sternoclavicular articular disk. (05 Mar 2000) |
| articular disc of temporomandibular joint | The fibrocartilaginous plate that separates the joint into upper and lower cavities. Synonym: discus articularis temporomandibularis, mandibular disk, temporomandibular articular disk. (05 Mar 2000) |
| bulging disc | <radiology> Broad-based disc extension outward in all directions with intact but weakened annulus fibrosus and posterior longitudinal ligament, age: greater than40 y.o (common finding), location: lumbar, cervical findings: concave anterior margin of thecal sac, nucleus pulposa hypointense on T1 and hyperintense on T2 (water loss through degeneration) see: degenerative disc disease (12 Dec 1998) |
| cervical disc herniation | <radiology> C6-7 (69%), C5-6 (19%), C7-T1 (10%), C4-5 (2%) see: degenerative disc disease (12 Dec 1998) |
| cervical disc syndrome | <syndrome> Pain, paresthesias, and sometimes weakness in the area of the distribution of one or more cervical roots, due to pressure of a protruded cervical intervertebral disc. Synonym: cervical compression syndrome. (05 Mar 2000) |
| micro-disc surgery | This describes a newer form of orthopaedic back surgery involving the insertion of a special hardware device through a small incision in the lower back. This form of surgery is indicated for those with intractable (unresponsive to medical therapy alone) disk disease of the lower spine (typically lumbar). The prolapsed disk is suction out of the back via a small tube inserted through the incision. (27 Sep 1997) |
| sacrococcygeal disc | A thin plate of fibrocartilage interposed between the sacrum and coccyx. (05 Mar 2000) |
| slipped disc | <orthopaedics> A condition that results in the abnormal protrusion (bulging), herniation or prolapse of a vertebral disc from its normal position in the vertebral column. The displaced disc may exert force on a nearby nerve root causing the typical neurologic symptoms of radiating pain (to an extremity), numbness, tingling and weakness. Recurrent episodes of severe back pain are common. Treatment includes non-steroidal anti-inflammatory drugs, corticosteroids and rest. More advanced cases may require surgical intervention (for example laminectomy, micro-disc surgery). (19 Jan 1998) |
| degenerative disc disease | <radiology> Plain film: narrowing of disc space; osteophytes; bone sclerosis, disc calcification, vacuum disc phenomenon (nitrogen at sites of negative pressure) MRI: endplate changes (Modic and deRoos), Type I (4%): decreased signal on T1; increased signal on T2; vascularised fibrous tissue, Type II (16%): increased T1; isointense T2; local fatty replacement of marrow, Type III: decreased T1; decreased T2; advanced sclerosis sequelae: disc bulging, disc herniation, disc sequestration, spinal stenosis (12 Dec 1998) |
