Fifty-six patients with ununited intracapsular fractures of the femoral neck were treated by internal fixation and muscle-pedicle bone grafting. All had some absorption of the femoral neck, and many had avascular necrosis of the femoral head. At operation the sclerosed surfaces of the fractures were freshened, the avascular femoral head was decompressed and the muscle-pedicle graft was fixed wi...

Introduction: This study is designed to explore the biomechanical principles of posterior bilateral pedicle screw on steps progressively and tight closure on every step for severe angular kyphosis and the indication conditions and clinical pathways of above new technique. Materials and Methods: A total of 90 patients have severe angular kyphosis, 37 males and 53 females, with an average age of ...

Most patients with spinal sagittal imbalance have a fusion mass that is either kyphotic or hypolordotic, with segments above or below the fusion that have subsequently degenerated. The four most common presentations include a patient who had a long fusion for adolescent idiopathic scoliosis with subsequent degeneration distally; a patient with degenerative sagittal imbalance in whom fusions hav...

STUDY DESIGN This study is a prospective, clinical study for lumbar degenerative kyphosis. PURPOSE To determine the factors affecting postoperative clinical outcomes in patients who undergo corrective osteotomy for lumbar degenerative kyphosis. OVERVIEW OF LITERATURE Only a small number of studies have reported clinical results for surgery for lumbar degenerative kyphosis. There are almost ...

The purpose of this retrospective study was to demonstrate the surgical outcomes of anterior spinal fusion (ASF) and posterior subtraction osteotomy (PSO) for osteoporotic vertebral collapse (OVC). Forty patients who underwent surgery for OVC at the thoracolumbar junction with neurological deficits were included in this study. ASF was primarily chosen for patients without vertebral compression ...

BACKGROUND Correction of fixed spinal imbalance in a sagittal and/or coronal plane frequently needs a tricolumnar wedge resection when the deformity is rigid. Complications associated with deformity correction surgery are pseudoarthrosis and implant failure located along the construct. The purposes of this study were to assess comparative rates of pseudoarthrosis (implant failure) at weaker poi...

PURPOSE OF THE STUDY The aim of the study is to present the technique of pedicle subtraction osteotomy (PSO) of the seventh cervical vertebra (C7) for correction of rigid kyphotic deformity of the cervicothoracic junction (C/Th) in patients with severe ankylosing spondylitis (AS).. MATERIAL AND METHODS The PSO technique for correction of rigid deformity of the C/Th spine was used in five pati...

neglected, untreated and delayed femur neck fractures are commonly encountered and the treatment dilemma arises especially when the patient is physiologically young and osteosynthesis is the preferred option. controversy exists in the current literature as the various head salvage surgeries like valgus subtrochanteric osteotomy, non-vascularized fibular bone grafting, muscle pedicle bone grafti...
