Minimally invasive fenestration for decompression of C2-C3 spinal stenosis.

Conventional techniques in neurosurgery such as laminectomy have been extensively displaced by minimally invasive types, owing to the character of complexity of cervical spinal region. Spinal canal stenosis at C2-C3 level is documented in the literature with the majority being caused by intervertebral disc herniations.This case reports a patient who presented with classical myelopathy symptoms and significant thickening of ligamentum flavum, while minimal spondylosis was detected at C2-C3 level.

Implementation of New Technology in Patients with Chronic Deep Brain Stimulation: Switching from Non-Rechargeable Constant Voltage to Rechargeable Constant Current Stimulation.

Introduction: Deep brain stimulation (DBS) for movement disorders has been mainly performed with constant voltage (CV) technology. More recently also constant current (CC) systems have been developed which theoretically might have additional advantages. Furthermore, rechargeable (RC) system implantable pulse generators (IPG) are increasingly being used rather than the former solely available non-rechargeable (NRC) IPGs.

Position-Dependent Dysfunction of Deep Brain Stimulation in Tourette Syndrome: Diagnostic Clues.

Background: Detection of defective deep brain stimulation (DBS) contacts/electrodes is sometimes challenging.

Case Report: We report a patient with Tourette syndrome (TS), who presented with abrupt tic increase and mild generalized headache 9 years after DBS implantation. On the suspicion of a hardware defect, a fracture of the DBS electrode and extension lead was ruled out by radiography and standard implantable pulse generator readouts.
