– See: – Burst Frx – Thoracic & Thoracolumbar Spine : – Posterolateral Decompression: – Discussion: – frx at this level are frequently due to relative immobility of thoracic spine compared to the lumbar spine; – upper thoracic spine (T1 … Read more
– See: – Burst Fractures – Thoracic and Thoracolumbar Spine: – Discussion: – results from hyperflexion, which produces wedge compression of one or more vertebral bodies; – due to the rigidity of the rib cage, most of these frxs are stable; – thoracic spinal … Read more
origin: the transverse process of the 6th to 10 Thoracic vertebrae; insertion: the spinous process of the 1st to 4th thoracic and 6th-7th cervical vertebrae; action: extends the spine and rotates it toward the opposite side; nerve supply: posterior rami of the thoracic nerves, T1 to T6; synergists: Longissimus Thoracis, Iliocostalis thoracis, Spinalis Thoracis
