Limbus vertebra is marginal interosseous herniation of the nucleus pulposus due to congenital abnormality, chronic stress and trauma to an immature spine during childhood and adolescence. The pathophysiology of limbus vertebra is likely to be similar and related to Schmorl’s nodes and Scheuermann’s disease.
How common is limbus vertebra?
The limbus vertebra is a rare condition poorly described in the medical literature. Marginal intrabody herniation of the nucleus pulposus resulting in the separation of a triangular bone fragment.
Is limbus vertebra a fracture?
A limbus vertebra is a bone tubercle formed by bone trauma on a vertebral body, bearing a radiographic similarity to a vertebral fracture. The anterior-superior corner of a single vertebra is the common site for this defect although it can also be seen at the inferior corner as well as the posterior or anterior margin.
What is a limbus?
Definition of limbus : the marginal region of the cornea of the eye by which it is continuous with the sclera.
How do you treat limbus vertebra?
Limbus vertebra is usually diasgnosed incidently and usually doesn’t need treetment. Symptomatic patients are treated conservatively but if conservative treatment fails surgical treatment may be needed. Usually total laminectomy is necessery for sufficient excision of limbus fragment [2].
What is a limbus fracture?
Introduction: Limbus vertebral fracture is an uncommon injury described in adolescents. It refers to the separation of a bony fragment from the unfused ring apophysis of lumbar vertebral end plate. It usually presents with back pain with/without radiculopathy masquerading an acute disc prolapse.
What can you do for limbus vertebrae?
What does the limbus do?
The limbus forms the border between the transparent cornea and opaque sclera, contains the pathways of aqueous humour outflow, and is the site of surgical incisions for cataract and glaucoma.
What is Schmorl node?
Schmorl nodes represent a herniation or an extrusion of the intervertebral disc nuclear material through the vertebral body endplate, with displacement of this material into the adjacent vertebral body [2]. The herniated tissue may form a defect in the upper or lower surface of the involved vertebra.
What does spondylosis pain feel like?
Patients often experience aching, stiffness, or pain in the mid back region described as a muscle spasm or tightness. If spondylosis causes pressure on the surrounding nerves there may be numbness, tingling or pain radiating into the chest, ribs, or abdominal areas known as radiculopathy.
What causes a limbus vertebra?
Limbus vertebrae result from an intrabody herniation of disc material. It can be mistaken for a fracture, infection or tumour.
What does limbus vertebra mean?
Limbus vertebra is a well-corticated unfused secondary ossification centre, usually of the anterosuperior vertebral body corner, that occurs secondary to herniation of the nucleus pulposus through the vertebral body endplate beneath the ring apophysis (see ossification of the vertebrae).
What is Limbus vertebrae?
Limbus vertebrae of the anterosuperior corner of a single vertebral body in the lumbar spine. Adult male with low back with no any history of remote or recent trauma. Limbus vertebrae result from an intrabody herniation of disc material. It can be mistaken for a fracture, infection or tumor.
