Intravenous lidocaine in spine surgery: A meta-analysis of randomized controlled trials.

Background: This study aimed to evaluate the role of intravenous lidocaine as a supplemental pain control modality in patients undergoing spine surgery.

Methods: We conducted a meta-analysis of randomized controlled trials (RCTs) involving the use of supplemental intravenous lidocaine in spine surgery. We developed a comprehensive search strategy to adequately screen for randomized controlled trials involving intravenous lidocaine in spine surgery.

Sagittal Spinal and Pelvic Parameters in Patients With Scheuermann's Disease: A Preliminary Study.

Background: Sagittal spinopelvic parameters remain poorly defined in patients with Scheuermann disease (SD). For example, although pelvic incidence (PI) should approximate lumbar lordosis (LL) by 10°, this is not true in patients with SD. This retrospective radiographic study was conducted to propose a new mathematical relationship between sagittal spinopelvic parameters in skeletally mature patients with SD.

Prophylactic adjacent-segment vertebroplasty following kyphoplasty for a single osteoporotic vertebral fracture and the risk of adjacent fractures: a retrospective study and clinical experience.

OBJECTIVE This study investigated the benefit of prophylactic vertebroplasty of the adjacent vertebrae in single-segment osteoporotic vertebral body fractures treated with kyphoplasty. METHODS All patients treated with kyphoplasty for osteoporotic single-segment fractures between January 2007 and August 2012 were included in this retrospective study. The patients received either kyphoplasty alone (kyphoplasty group) or kyphoplasty with additional vertebroplasty of the adjacent segment (vertebroplasty group).
