Transforaminal Endoscopic Solution to a Kyphoplasty Complication: Technical Note.

Kyphoplasty is a minimally invasive spine surgical procedure performed to stabilize and treat the pain caused by a spine compression fracture. Complications are rare with kyphoplasty and include cement extrusion into the vertebral canal leading to spinal cord or nerve root compression. Herein, the authors present a case of a 72-year-old woman who presented with symptoms of a right L2 radiculopathy after a kyphoplasty procedure. Computed tomography imaging showed leakage of the kyphoplasty cement into the neural foramen above and medial to the right L2 pedicle. A transforaminal endoscopic surgical approach was used to remove the cement and decompress the L2 nerve. The patient's postoperative clinical course was uneventful. Clinicians should be aware that for the treatment of complications to vertebroplasty and kyphoplasty procedures, minimally invasive transforaminal endoscopic surgery is one option to avoid the destabilizing effects of laminectomy and facetectomy.
