Introduction
IONM is used in a variety of spinal surgeries to assess spinal cord and nerve root function.
Relevant clinical symptoms
1. Foot drop. Foot drop is an abnormality in gait that makes it difficult to lift the foot. Injury to the deep peroneal nerve is the most common cause of foot drop. The peroneal nerve is a branch of the sciatic nerve that exits at nerve roots L4-S2 and innervates the anterior and lateral compartments of the leg, including the tibialis anterior, the muscle that allows us to lift our foot.
Spinal instrumentation
Scoliosis surgery
1. Introduction. Scoliosis is a deformity in the vertical alignment of the spine. Scoliosis is defined as a lateral curvature of the spine that includes rotation of the vertebrae. The misalignment can be in the shape of a C or an S. Scoliosis is diagnosed when there is at least a 10 degree angle in the alignment of the vertebrae as viewed in the anterior-posterior plane. Scoliosis is broadly classified as congenital, neuromuscular, and idiopathic in origin. Physicians characterize the type of scoliosis using the Lenke classification system.
