A TLSO is primarily indicated for which of the following conditions?

Accepted Answer

Thoracolumbar burst fractures

Question 2

Which spinal orthosis is most appropriate for managing adolescent idiopathic scoliosis with a Cobb angle between 25° and 40°?

Accepted Answer

Boston brace

Answer

The Boston brace (TLSO) is the most widely prescribed orthosis for adolescent idiopathic scoliosis in the thoracolumbar and lumbar regions within that Cobb angle range.

Question 3

The three-point pressure principle used in spinal orthotics involves applying corrective forces in how many directions?

Accepted Answer

Three directions, with two forces on one side and one counterforce on the other

Answer

The three-point pressure system applies two forces on one side of the deformity and a single counterforce between them on the opposite side to achieve correction.

Question 4

A patient with an L4-L5 disc herniation and mild instability would most likely be fitted with which orthosis?

Accepted Answer

Lumbar corset with stays

Answer

A lumbar corset with rigid stays provides mild support and proprioceptive feedback for lumbar disc pathology without full rigid immobilization.

Question 5

Which of the following is a rigid lumbar orthosis that limits flexion, extension, and lateral bending but allows some rotation?

Chair-back LSO

Answer

The chair-back LSO uses rigid posterior uprights and abdominal apron to limit lumbar motion in three planes while permitting some axial rotation.
