Risk of developing seizure after percutaneous endoscopic lumbar discectomy.

Study Design: A retrospective analysis in patients who underwent percutaneous endoscopic lumbar discectomy (PELD) and developed seizures during the procedure; and to identify the risk of developing seizure during PELD by measuring cervical epidural pressure.

Objective: To evaluate clinical significance, characteristics, and risk factors for developing seizure and neck pain in patients undergoing PELD.

Summary And Background Data: Increased epidural pressure during PELD has been reported earlier.

CT-guided percutaneous vertebroplasty in the treatment of an upper thoracic compression fracture.

Percutaneous vertebroplasty (PVP) has been used to relieve pain and to prevent further collapse of the vertebral body in patients with an osteoporotic compression fracture. The most commonly affected site for the use of PVP is the thoracolumbar junction. There are few reports that have described on the usefulness of PVP in the treatment of a high thoracic compression fracture.

Computed tomography-guided percutaneous facet screw fixation in the lumbar spine. Technical note.

The authors describe a new minimally invasive technique for posterior supplementation using percutaneous translaminar facet screw (TFS) fixation with computed tomography (CT) guidance. Oblique axial images were used to determine facet screw fixation sites. After the induction of local anesthesia and conscious sedation, a guide pin was inserted and guided with a laser mounted on the CT gantry.

Low-dose botulinum toxin type A for the treatment of refractory piriformis syndrome.

Study Objectives: To evaluate the efficacy of a single, low-dose injection of botulinum toxin type A in relieving pain in Korean patients with piriformis syndrome resistant to conventional therapy, and to assess the drug's influence on these patients' quality of life.

Design: Prospective, single-site, open-label trial.

Setting: Rehabilitation medicine clinic in Seoul, Korea.

Operative failure of percutaneous endoscopic lumbar discectomy: a radiologic analysis of 55 cases.

Study Design: A retrospective study.

Objective: To determine the range of lumbar disc herniation that can be addressed effectively using current endoscopic techniques.

Summary Of Background Data: The current technical limitation of the procedure in terms of the location and size of the herniation has not been fully documented in previous studies.

Minimally invasive anterior lumbar interbody fusion followed by percutaneous pedicle screw fixation for isthmic spondylolisthesis.

Background Context: Most surgeons have thought that posterior decompression is necessary to treat isthmic spondylolisthesis with leg pain. However, the surgical procedure not only requires wide muscle dissection but can also lead to spinal instability. The authors' treatment concept for isthmic spondylolisthesis is one-stage anterior reduction and posterior stabilization with minimally invasive surgical procedure without touching the spinal thecal sac and nerve.

Percutaneous endoscopic lumbar discectomy for recurrent disc herniation: surgical technique, outcome, and prognostic factors of 43 consecutive cases.

Study Design: A retrospective study of 43 consecutive patients who underwent percutaneous endoscopic lumbar discectomy for recurrent disc herniation.

Objectives: To evaluate the efficacy of endoscopic discectomy for recurrent disc herniations and to determine the prognostic factors affecting surgical outcome.

Summary Of Background Data: Repeated open discectomy with or without fusion has been the most common procedure for a recurrent lumbar disc herniation.
