Background context Correction of adult spinal deformity (ASD) by long segment instrumented fusion is an increasingly common surgical intervention. However, it associated with high rates complications and revision surgery, especially in the elderly patient population. The construct stiffness thoracolumbar has been postulated to lead a higher incidence proximal junctional kyphosis (PJK) failure (...

Background: Proximal junctional failure (PJF) is a known complication following posterior spinal fusion surgery and can be defined simply as proximal kyphosis that requires surgical revision of the instrumentation. PJF associated with pain, decreased neurologic function, infection, increased morbidity. There little literature on this topic in children especially specific techniques for surgery....

OBJECTIVE To evaluate the results of the surgical treatment of the spinal Kyphosis using the Ponte's technique (multiple posterior osteotomies). METHODS Ten patients (8 with Scheuermann's kyphosis and 2 with kyphosis after laminectomy) submitted to surgical correction of kyphotic deformity greater than 70° were retrospectively assessed. The age at the surgical time ranged from 12 to 20 years ...

Introduction: Children with severe kyphosis are prone to developing neurologic compromise, poor respiratory function and possible early death. Early identification and surgical intervention has proven to be effective. However they carry the highest surgical risk of all the spine deformities. Objectives: To present the surgical results and complications of patients with severe kyphosis treated a...

STUDY DESIGN Retrospective study. OBJECTIVE To compare 2 methods of selecting the lowest instrumented vertebra (LIV) on the rates of revision surgery for distal junctional kyphosis (DJK) following treatment for Scheuermann's kyphosis (SK). METHODS A retrospective review of patients who have undergone surgical treatment for SK was performed. Forty-four patients were divided into 2 groups bas...

BACKGROUND Incidence of complications and reoperations between pedicle screw (PS) and hybrid instrumentations (HI) are still controversial in adolescent idiopathic scoliosis (AIS) patients. A systematic review and meta-analysis were performed to compare overall complications, reoperations, and radiographic outcomes between the 2 constructs. METHODS Strictly followed the PRISMA 2009 guidelines...
