What is anterior wedging of T11?
Definition. An abnormality of the shape of the thoracic vertebra T11 such that it is wedge-shaped (narrow towards the front). [ from HPO]
What causes a wedged vertebrae?
This deformity occurs when the body of the vertebra becomes fragmented as in fracture crush, or when the bone becomes sufficiently softened from pathologic processes so that the body weight compresses the vertebra from above downward.
Is wedging of vertebrae a fracture?
Wedge fracture — This fracture usually occurs in the front of the vertebra, collapsing the bone in the front of the spine and leaving the back of the same bone unchanged, which results in the vertebra taking on a wedge shape.
What causes anterior wedging of vertebrae?
Anterior wedge fractures are fractures that occur when the vertebrae in the spine break down from some form of trauma. The fracture can also be caused by cancer, osteoporosis and any number of other conditions. Symptoms often include weakness and pain but can in rare cases cause nerve pains, tingling or incontinence.
What does wedging of vertebrae mean?
Introduction. A wedge fracture is a vertebral compression fracture occurring anteriorly or laterally. Viewed, the affected vertebra resembles a wedge. These fractures are more commonly found in the thoracic spine, which is rather rigid displaying only a few degrees of flexion and extension.
What is a T11 wedge fracture?
Compression fractures of the spine usually occur at the bottom part of the thoracic spine (T11 and T12) and the first vertebra of the lumbar spine (L1). Compression fractures of the spine generally occur from too much pressure on the vertebral body.
Where is the T11 vertebral body?
thoracic spine
The eleventh thoracic vertebra (T11) is located near the bottom of the thoracic spine. Generally, the spinal bones are larger and heavier the further down they are located. This helps each vertebra to support the weight of the vertebrae above it, as well as the weight of the skull and brain.
What is T11 vertebral body?
The T11 is one of the two lowest vertebrae in your spinal thoracic region. Like the other thoracic vertebrae, they are attached to your ribcage, which helps to protect them from direct harm, though they can be subject to damage from compression fractures.
What nerves are affected by T11 and T12?
At the T1 through T11 levels, the ventral ramus eventually becomes an intercostal nerve that travels along the same path as the ribs (specifically between the innermost and internal intercostal muscles that connect adjacent ribs). At T12, the ventral ramus becomes a subcostal nerve that travels beneath the twelfth rib.
