Background Data: Although the use of Cotrel-Dubousset (CD) instrumentation has improved results of operative treatment of scoliotic deformities, this technique may be associated with increased risk of neurologic injury.
Case Histories: Two cases of neurologic complications immediately after insertion of lumbar laminar hooks during CD instrumentation for correction of scoliosis are reported.
Methods: Between 1986 and 1992, the authors performed 220 CD instrumentations for various spinal deformities. All patients were monitored with posterior tibial nerve somatosensory cortical evoked potentials (PTN-SSEPs).
Conclusion: These cases demonstrate that caution should be exercised during introduction of laminar hooks on the concave side during CD instrumentation for scoliotic deformities. Continuous neurophysiologic monitoring of spinal cord conduction may aid in early detection of local compression at the spinal cord or cauda equina level.

Introduction: Neuromuscular scoliosis (NMS) is associated with an abnormal muscle tone. Traditional conservative treatments, with the historical practice of early posterior fusion, have proven ineffective. Recently, growth-sparing techniques have gained traction owing to their ability to maximize trunk height.

Introduction: Traumatic injuries of the spine requiring surgery are rare in infancy. Fusion procedures in the very young are not well-described at the atlanto-occipital junction or subaxial spine. Here we describe novel segmental posterior instrumentation in a severe spinal column disruption in an infant.

Intracortical inhibition in motor cortex (M1) regulates movement and motor learning. If cortical and thalamic inputs target different inhibitory cell types in different layers, then these afferents may play different roles in regulating M1 output. Using mice of both sexes, we quantified input to two main classes of M1 interneurons, parvalbumin+ (PV+) cells and somatostatin+ (SOM+) cells, using monosynaptic rabies tracing.
